Description

Combined Water and Power System

The present invention relates to a water-electricity simultaneous production system, and more particularly to a water-electricity simultaneous production system including a generator for producing electricity and a water-producing unit for producing water.

Generators using diesel engines or gas engines generate engine heat and exhaust gas heat (arrangement) during operation.

At this time, generally, engine heat is cooled using cooling water and a radiator, and the arrangement is recovered and used as heat energy such as steam or hot water.

Unlike the arrangement in which the heat is recovered by heat energy, the engine heat is low in quality, and it is difficult to recover heat, so it is cooled using cooling water and a radiator. 1, the high temperature cooling water CWH warmed by the generator G flows into the radiator RA, is cooled down to the low temperature cooling water CWL through the cooling fan FA, So that the engine is thermally cooled. Therefore, circulation of the cooling water and operation of the cooling fan correspond to a process requiring additional energy.

On the other hand, even in the case of heat energy recovered from the array, seasonal demand fluctuations occur. In general, demand is high in winter, while demand in summer is very low.

To compensate for this, additional absorption refrigerator units may be installed in the generator to produce cooling energy from the heat energy recovered from the arrangement and used for engine thermal cooling.

However, the absorption type cold and hot water generating apparatus installed in the generator has a problem that maintenance is difficult. In addition, the absorption type cold / hot water heater apparatus is expensive and its accessibility is very low in a general generator installation environment.

Here, a request is made to more efficiently secure an energy supply source for engine thermal cooling. The inventors of the present invention have studied for a long time in order to solve the requests in the field, and after trial and error, have come to complete the present invention.

An embodiment of the present invention provides a water-electricity simultaneous production system that efficiently recovers engine heat from an abandoned power plant in a power plant producing a large amount of electricity to produce water.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

A water-electricity simultaneous production system according to an embodiment of the present invention includes: a power generation unit including an engine power generation system that receives cooling water from a cooling water line; A constantifying unit connected to the generators through a raw water line and having the high temperature coolant discharged from the generators as raw water; And a constant storage unit connected to the water leveling unit through a circulation line and circulating the low temperature water to the water leveling unit and flowing a constant converted from the raw water by the water leveling unit.

And a discharge line connected to the water leveling unit, wherein the raw water can be discharged to the outside through the discharge line through the water leveling unit.

The cooling water before the cooling water is introduced into the power generation unit may be heat-exchanged with the constant water before the cooling water is introduced into the water-cooling unit from the cooling water line, and the first heat exchanger is disposed on the cooling water line and the circulation line. .

And a second heat exchanger disposed on the cooling water line and the discharge line, wherein the cooling water before being introduced into the power generation section is heat-exchanged with the raw water discharged from the constantifying section in the second heat exchanger.

The cooling water may flow through the first heat exchanger and the second heat exchanger sequentially to the power generation unit.

And an exhaust line connected to the generators, wherein the exhaust gas discharged from the generators can be exhausted to the outside through the exhaust line.

And a third heat exchanger disposed on the raw water line and the exhaust line, wherein the raw water before the raw water is allowed to exchange heat with the exhaust gas in the third heat exchanger.

And a pretreatment unit disposed on the cooling water line, wherein the organic and inorganic materials contained in the cooling water before the cooling water is introduced into the power generation unit can be removed from the pretreatment unit.

The cooling water may flow through the first heat exchanger, the second heat exchanger, and the pretreatment unit sequentially to the power generation unit.

And a power line connected to the generators to transmit power generated by the generators to the outside, wherein the power line is disposed on the power line.

Further comprising a constant line connected to the constant storage unit to supply the constant to the outside, wherein the constant supplied to the outside from the constant storage unit is a constant value, At least one of disinfection, pH adjustment and hardness adjustment may be performed in the post-treatment section.

This technology can provide a water-electricity simultaneous production system that efficiently recovers engine heat from an abandoned power plant in a power plant producing a large amount of electricity to produce water.

In addition, this technology can provide a simultaneous water-electricity production system capable of simultaneously producing water and electricity in an energy-efficient manner.

In addition, the present technology can reduce the energy consumption considerably because a separate radiator for cooling is not required, and power generation efficiency can be greatly improved by recovering engine heat that has not been recovered in the past and utilizing it as a heat source for constantization.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

Hereinafter, the most preferred embodiment of the present invention will be described. In the drawings, the thickness and the spacing are expressed for convenience of explanation, and can be exaggerated relative to the actual physical thickness. In describing the present invention, known configurations irrespective of the gist of the present invention may be omitted. It should be noted that, in the case of adding the reference numerals to the constituent elements of the drawings, the same constituent elements have the same number as much as possible even if they are displayed on different drawings.

2 is a diagram showing a detailed configuration of a water-electricity simultaneous production system 1 according to an embodiment of the present invention.

2, the water-electricity simultaneous production system 1 includes a power generation unit 10 composed of a plurality of generators, a water supply unit 20 for converting raw water into a constant water, and a constant storage unit 30).

It also includes a cooling water line L1, a raw water line L2, a discharge line L3, a circulation line Lc and a constant line Lw.

The cooling water line L1 introduces cooling water SW for cooling the power generation portion from the outside to the power generation portion 10. The raw water line L2 introduces raw water SW for constantization from the power generating section 10 to the water generating section 20. The discharge line (L3) discharges the raw water (SW) passing through the water supply section (20) to the outside. The circulation line (Lc) circulates a constant for constantization from the constant storage section (30) to the constantifying section (20). The constant line Lw supplies a constant FW from the constant storage unit 30 to the outside.

Each of the lines L1, L2, L3, Lc, and Lw may be formed in the form of a pipe through which cooling water, raw water, or constant can flow. As described later, since the cooling water may be seawater or fresh water, aluminum or stainless steel (SUS), which is excellent in corrosion resistance to salt, can be applied as a material of the lines. Particularly, a material excellent in corrosion resistance can be applied to the cooling water line L1, the raw water line L2 and the discharge line L3, which have relatively high salinity.

The power generation section 10 includes a plurality of water-cooled engine generators 11, 12 and 13. Many engine generators constitute an engine power generation system. The water-electricity simultaneous production system 1 according to the embodiment of the present invention may be a power generation plant in that it includes a power generation unit composed of a plurality of generators.

In the power generation section, three generators are connected in parallel to each other, and the power produced by each of them is collected into a power line Lp, which is one line, and can be supplied to the outside, that is, to the power consumer. Although three generators are shown in the drawing, the present invention is not limited to the number.

The engine can be of various types, such as a diesel engine, a gasoline engine, a gas engine, or a hybrid engine.

The cooling water SW applied to the generators 11, 12, 13 may be seawater or fresh water. That is, seawater or fresh water can be directly used as cooling water flowing in the engine.

Therefore, a material such as aluminum or SUS excellent in corrosion resistance to saline can be applied to the inside of the engine. For example, the water jacket inside the engine can be made of aluminum or SUS.

Through the cooling water line L1 described above, seawater or fresh water flows directly into the engine of each of the generators.

As another example, the engine may be cooled by the presence of separate cooling water (an antifreeze such as ethylene glycol) circulating in the engine of the generators, and heat exchange with the cooling water SW flowing into the power generation portion. That is, the cooling water SW flows into the power generation section through the cooling water line L1, and the introduced cooling water SW exchanges heat with the antifreeze circulating in the engine while passing through the engine of the power generation section. It can be provided as raw hot water. In either case, the cooling water SW flowing into the generator through the cooling water line is the same in that heat is obtained from the engine.

The generators can share one cooling water line (L1) in series or in parallel. That is, seawater or fresh water flows from the outside through one cooling water line L1, and the engines of the generators can receive seawater or fresh water from one cooling water line L1.

The cooling water SW is heated to 50 ° C or higher as it passes through the engines in the generators, and the water-making unit 20, which will be described later, directly converts the cooling water SW having the high temperature into raw water.

The water supply unit 20 can constantize the raw water by using a membrane distillation method (Membrane Distillation (MD)). Membrane distillation is a method of using thermal energy and a membrane in which a porous membrane exists. Membrane distillation methods applicable to the constant-temperature processes include direct contact membrane distillation (DCMD), air-gap membrane distillation (AGMD), vacuum membrane distillation (VMD), vacuum gas membrane distillation (SGMD), sweep gas membrane distillation (OMD), and osmotic membrane distillation (OMD).

Also, the present invention is not limited to this, and the water supply unit can constantize the raw water by using a membrane contactor having a wider concept than the membrane distillation method. The method of transferring the influent water in the form of water vapor using the membrane and heat, and then producing the water by condensing and recovering it. The effect of producing the constant water is the same although the detailed application method is different depending on the presence of the air and the hydrophilic / hydrophobic material.

For convenience of explanation, it is assumed in the present invention that the water supply unit 20 directly converts the raw water by using the contact membrane distillation method, but the present invention is not limited thereto.

The water supply unit 20 according to an embodiment of the present invention may include a vaporizer for receiving high temperature raw water, a condenser for flowing low temperature water, and a membrane for separating high temperature raw water and low temperature constant. For example, the evaporator may be a region corresponding to the lower portion of the humidifier 20 shown in FIG. 1, the condenser may be a region corresponding to the upper portion of the humidifier 20 shown in FIG. 1, And may be an area corresponding to an intermediate portion of the water supply unit 20 shown in FIG. The four arrows through the middle indicate the direction of the steam flow.

The hot raw water flowing into the water producing unit is discharged to the outside through the evaporating unit. The low-temperature constant introduced into the water-producing unit passes through the condensing unit and is recovered to a constant-storage unit, which will be described later. Then, the membrane is subjected to a direct contact type membrane distillation reaction so that hot raw water passing through the evaporation portion is brought into contact with the membrane surface and converted into a constant. That is, the steam pressure difference between the high-temperature raw water on the evaporator and the low-temperature constant on the condenser, which is divided by the membrane, is made constant by the driving force. For this purpose, the membrane can be formed of a hydrophobic polymer membrane capable of passing water vapor, and the membrane can be formed by passing water vapor present in the high-temperature raw water flowing into the evaporator unit through a plurality of pores formed in the membrane, .

The raw water of high temperature flows into the water generating unit 20 through the raw water line L2 described above.

The water supply unit 20 supplies high temperature raw water, that is, high temperature cooling water SW, from the power generation unit 10 through the raw water line L2, and performs the water treatment.

For this purpose, the water supply unit 20 is connected to the power generation unit 10 through the raw water line L2. That is, the water leveling unit 20 is connected to the generators 11, 12 and 13 of the power generation unit through the raw water line L2.

That is, the water supply unit constantly flows the high-temperature cooling water SW discharged from the generators through the raw water line L2 as raw water.

The high temperature cooling water SW passing through the water generating unit 20 is discharged to the outside through the discharge line L3 described above.

Further, in order to make such a constant, a low temperature constant is introduced from the constant storage section 30 into the water conditioning section 20 through the circulation line Lc.

That is, the water supply unit 20 receives a low temperature constant from the constant storage unit 30 through the circulation line Lc, and performs a constantization process.

In other words, the water supply unit 20 receives the high-temperature raw water through the raw water line L2 and receives the low-temperature constant through the circulation line Lc to perform the constantization process.

For this purpose, the constant storage unit 30 is connected to the water conditioning unit 20 through the circulation line Lc.

The low temperature constant is maintained at a low temperature by cooling to a level similar to the atmospheric temperature due to heat loss through the constant storage section 30 and the circulation line Lc.

The constant storage unit 30 receives a constant converted from raw water by the water conditioning unit 20 while circulating a low temperature constant to the water generating unit 20, and stores the constant.

The constant FW stored in the constant storage unit 30 through the constant line Lw is supplied to the outside, that is, to the constant consumer.

The cooling water SW which is seawater or fresh water flows into the power generation section 10 through the cooling water line L1 and the cooling water of the high temperature heated by cooling the engines of the power generation section flows through the raw water line L2, The low temperature water flowing from the water storage unit 30 is circulated to the water supply unit 20 through the inlet and discharge line L3 and the cooling water SW which is the seawater or fresh water is circulated through the constant water FW ).

As described above, the simultaneous water-electricity production system according to the embodiment of the present invention produces electric energy by using fossil fuel as a power generation plant, and applies seawater or fresh water as engine cooling water to directly heat the heated cooling water to a high temperature It is a method that can produce water and electricity at the same time.

According to the embodiment of the present invention, a radiator for separate cooling as shown in FIG. 1 is not required, and energy consumption is greatly reduced. In addition, the power generation efficiency is greatly improved by recovering the engine heat that has not been recovered and using it as a heat source for constantization.

3 is a diagram showing a detailed configuration of a water-electricity simultaneous production system 2 according to another embodiment of the present invention.

The simultaneous water-electricity production system of FIG. 3 differs from the water-electricity simultaneous production system of FIG. 2 in that it further includes a plurality of heat exchangers. For convenience of explanation, .

Referring to FIG. 3, the water-electricity simultaneous production system 2 may further include heat exchangers 40, 50 and 60. The heat exchangers may include a first heat exchanger (40), a second heat exchanger (50), and a third heat exchanger (60).

Various heat exchangers such as a liquid-liquid heat exchanger and a liquid-gas heat exchanger may be used as the heat exchanger. According to the embodiment of the present invention, the first heat exchanger and the second heat exchanger may be a liquid- The heat exchanger, and the third heat exchanger may be liquid-gas heat exchange type heat exchangers.

The first heat exchanger 40 is disposed on the cooling water line L1 and the circulation line Lc described above. That is, the cooling water line and the circulation line may be formed to pass through the first heat exchanger. For example, the cooling water line and the circulation line may pass through the first heat exchanger.

In the first heat exchanger (40), heat can be transferred from the low temperature constant circulating in the circulation line (Lc) to seawater or fresh water flowing along the cooling water line (L1). The heat transfer from the low temperature constant corresponding to a relatively high temperature to the sea water or the fresh water corresponding to a relatively low temperature can be made.

The constant stored in the constant storage unit 30 is circulated through the water supply unit 20 as described above. At this time, some heat exchange with the hot water at the high temperature can be performed, and thus, the temperature is stored in the constant storage unit . This may result in an increase in the temperature of the water flowing into the desalination part, thereby lowering the water production efficiency.

Accordingly, the first heat exchanger 40 according to the embodiment of the present invention reduces the temperature of the water flowing into the water generating section 20 from the water storing section 30 (that is, So that it can be maintained at an optimum temperature condition for water supply).

For example, when the constant temperature of 20 ° C is partially exchanged with the raw water of high temperature of 80 ° C and the temperature of the water is 25 ° C, the heat is exchanged with the seawater of 10 ° C Lt; RTI ID = 0.0 > C, < / RTI >

At this time, although the seawater is preheated before being introduced into the generator by the first heat exchanger, the higher the temperature is, the more favorable the water supply is, so that it is preferable from the viewpoint of the overall energy efficiency.

The heat exchange system using the temperature difference between the two liquids in the first heat exchanger (the low-temperature constant water flowing into the water-producing unit-the seawater or fresh water flowing into the power generation unit) does not require any additional energy, It has the advantage of matching.

Subsequently, referring to FIG. 3, the second heat exchanger 50 is disposed on the cooling water line L1 and the discharge line L3 described above. That is, the cooling water line and the discharge line may be formed to pass through the second heat exchanger. For example, the cooling water line and the discharge line may pass through the second heat exchanger.

In the second heat exchanger 50, heat can be transferred to the seawater or fresh water flowing along the cooling water line L1 from the hot raw water SW discharged through the discharge line L3. The heat transfer from the relatively hot high temperature raw water to the relatively low temperature sea water or fresh water can be made.

Although some heat loss is generated for the production of water in the constantifying unit, the raw water of high temperature (that is, high-temperature concentrated water) passing through the water making unit 20 still contains a lot of heat energy. .

The second heat exchanger 50 according to the embodiment of the present invention reduces the temperature of the high-temperature concentrated water discharged from the water supply line 20 through the discharge line L3 (that is, The water-heat simultaneous production system can be operated in an eco-friendly manner by taking the heat of the water and transferring it to the seawater flowing into the power generation section).

For example, the high-temperature concentrated water of 75 캜 discharged from the water-producing unit can be discharged to the outside at a low temperature of 30 캜 by preliminarily exchanging the concentrated water with seawater at 10 캜 before discharging.

At this time, the seawater is heated before being introduced into the generator by the second heat exchanger. However, as described above, the higher the temperature after passing through the generator, the more favorable the water supply.

Further, the heat exchange system using the temperature difference between the two liquids in the second heat exchanger (the seawater or the fresh water flowing into the high-temperature concentrated water-power generation unit discharged from the constantifying unit) does not require any additional energy, The temperature can be adjusted.

According to an embodiment of the present invention, the cooling water flowing into the power generation unit can flow into the power generation unit 10 sequentially through the first heat exchanger 40 and the second heat exchanger 50. The temperature of the high-temperature concentrated water passing through the second heat exchanger is much higher than the low temperature constant passing through the first heat exchanger, so that it is preferable to pass the first heat exchanger and then the second heat exchanger considering the heat transfer efficiency. If the first heat exchanger passes first, there may be a situation where the cooling water has a temperature higher than the low temperature constant due to the influence of the high-temperature concentrated water, and this situation results in the fact that the temperature of the low temperature constant is rather increased in the first heat exchanger .

Subsequently, referring to FIG. 3, the third heat exchanger 60 is disposed on the raw water line L2 described above. And is disposed on the exhaust line Le, which will be described later.

The exhaust line Le is provided in the water-electricity simultaneous production system 2 as a component for discharging the exhaust gas discharged from the generators 11, 12, 13 to the outside.

As described above, the three generators are connected in parallel to each other in the power generation section, and the exhaust gas discharged from each generator engine can be collected into an exhaust line Le, which is one line, and exhausted to the outside. Further, the generators may share one exhaust line Le. The exhaust line Le may be configured in the form of a pipe through which the exhaust gas can flow.

The raw water line L2 and the exhaust line Le may be formed to pass through the third heat exchanger 60. [ For example, the raw water line and the exhaust line may pass through the third heat exchanger.

In the third heat exchanger 60, heat can be transferred from the hot exhaust gas G discharged through the exhaust line Le to the hot raw water flowing along the raw water line L2. Since the exhaust gas is as small as 200 DEG C to as large as 800 DEG C, heat transfer can be performed from the exhaust gas corresponding to a relatively high temperature to the raw water of a high temperature corresponding to a relatively low temperature. Heat transfer takes place between the liquid and the gas.

By this third heat exchanger, the temperature of the raw water flowing into the water-supplying unit can be increased (the water-cooling efficiency tends to increase as the temperature of the raw water increases), and thus, (That is, the third heat exchanger formed in the exhaust line) is present, the amount of the raw water flowing into the water supply portion can be increased to such a degree that a more favorable condition for the water supply can be created.

For example, the high temperature raw water of 60 ° C flowing into the water supply line through the raw water line is heat-exchanged with the exhaust gas of 300 ° C in advance so as to be introduced into the constantizing section at a temperature condition favorable for further watering at 70 ° C can do.

In addition, for example, the amount of the raw water flowing into the constantifying section through the raw water line is doubled, and therefore, even if the raw water is at a temperature lower than the above-mentioned example of 30 ° C, The exhaust gas can sufficiently flow through the exhaust gas at 300 ° C to be introduced into the water-producing section in the raw water state at a high temperature of 70 ° C.

Similarly, the heat exchange system using the temperature difference between the liquid-gas (the hot raw water flowing through the raw water line and the exhaust gas flowing through the exhaust line) in the third heat exchanger does not require any additional energy, And the like.

4 is a diagram showing a detailed configuration of a water-electricity simultaneous production system 3 according to another embodiment of the present invention.

The simultaneous water-electricity production system of FIG. 4 differs from the water-electricity simultaneous production system of FIGS. 2 and 3 in that it further includes a preprocessing unit, a power storage unit, and a post-processing unit. We will focus on the differences.

4, the water-electricity simultaneous production system 3 may further include a preprocessing unit 70, a power storage unit 80, and a post-processing unit 90.

The pretreatment unit 70 is disposed on the above-described cooling water line L1.

Therefore, the organic and inorganic substances contained in the cooling water before being introduced into the power generation section can be removed from the pretreatment section.

The pretreatment unit is a component for removing organic and inorganic substances such as colloids, microorganisms, and sand except for the ionic substances contained in seawater or fresh water, and a process using one or more of physical, chemical and biological methods can be used .

The power storage unit 80 may be disposed on the power line Lp described above.

Thus, the electric power produced from each of the generators may be collected into one electric power line Lp and stored in the electric power storage unit 80 before being supplied to the electric power consumer.

The power storage unit 80 may be an ESS (Energy Storage System). The power storage unit may include a battery such as a lithium ion battery, a sodium sulfur battery, a redox flow battery, or a super capacitor.

The power storage unit saves the electric energy generated by the power generation unit when there is no demand for the electric power, and supplies the electric power to the demand source when necessary, thereby improving the power use efficiency.

The post-processing unit 90 is disposed on the above-mentioned constant line Lw.

Therefore, the water may be supplied to the customer after at least one of disinfection, pH adjustment, and hardness adjustment is performed in the post-treatment unit before being supplied to the water user from the water storage unit 30. [

Fig. 5 is a flowchart schematically showing an operation method of the water-electricity simultaneous production system 3 of Fig. 4 according to the passage of time.

Referring to FIG. 5, it is determined whether there is an electric power demand from the electric power consumer (S10).

As a result of the determination in step S10, if there is a demand for electric power, the power generator is operated (S20).

If it is determined in step S10 that there is no power demand, the process goes to step S11 in which it is determined whether there is a demand to be stored in the power storage unit.

As a result of the determination in step S11, if there is a demand for power storage, the power generation unit is operated (S20).

If it is determined in step S11 that there is no power storage demand, the process goes to step S12 for determining whether there is a constant demand from the constant consumer.

As a result of the determination in step S12, if there is a constant demand, the power generation unit is operated (S20). If there is no constant demand as a result of the determination in step S12, the power generation unit is terminated (S13). The power generation section end step (S13) may include not only terminating the power generation section in operation but also confirming the stationary state of the power generation section that is not in operation.

Subsequently, after the power generation unit is operated, it is determined whether there is a constant demand from the constant consumer (S30).

If it is determined in step S30 that there is a constant demand, the constantizing unit is operated (S40). If it is determined in step S30 that there is no constant demand, the process proceeds to step S31 to determine whether there is a demand to be stored in the constant storage unit.

As a result of the determination in step S31, if there is a constant storage demand, the constantifying unit is operated in step S40. If it is determined in step S31 that there is no constant storage demand, the constantifying unit is terminated in step S32. The step S32 for ending the watering part may include not only terminating the watering part in operation but also checking the stopping state of the watering part that is not in operation.

Subsequently, after the constantifying section is activated, the process may proceed to step S10. The subsequent steps are the same as described above.

As described above, according to the embodiment of the present invention, it is possible to provide a water-electricity simultaneous production system that efficiently recovers exhausted engine heat in a power generation plant producing a large amount of electricity to produce water.
