Description
Technical field:
The present invention relates to the energy and power technology field, specifically refer to: adopt the hot and cold pump combination technique of liquid-gas phase transition to draw the heat energy in the normal-temperature water and convert thermal gradient energy to, adopt the liquid-gas phase transition generator set thermal gradient energy to be converted to a kind of technique device of electric energy then.
Background technique:
It is predicted: to the fifties in this century, three big main energy sources (oil, coal, rock gas) in the world all will exhaust, and all can not fundamentally solve problem of energy crisis as multiple new energy such as solar energy, wind energies at present.Scientist thinks: Hydrogen Energy most possibly becomes a kind of termination energy in 21 century; Yet ITER highly visible plan, its input quite huge (tentatively dropping into 10,000,000,000 Euros), and just entered development, the result is difficult to prediction.
People know that solar energy is the source of all things on earth energy on the earth, but its energy that arrives ground disperses, be difficult to by focus utilization, and 70% be the water surface on the earth, and the thermal capacitance of water is very high 1.0Carl/g. ℃, so a huge solar energy receiver is not only in the ocean, also be a huge energy accumulator simultaneously; People wish always and can extract utilization to the heat energy in the water such as ocean for a long time.
After products such as the air-conditioning that adopts contrary Carnot's cycle, refrigerator come out, it is found that heating with process of refrigerastion is not the process of transformation of energy, be not subjected to the restriction of the energy conversion efficiency limit 100%, in the liquid-gas phase transition process, can carry a lot of heats with electricity seldom, thereby form certain thermal gradient energy; So the someone wants that the thermal gradient energy that utilizes contrary Carnot's cycle to form generates electricity very early, but because the conversion efficiency of low temperature difference power generation system is too low, can't develop such electricity generating device at all.
Afterwards along with the progress of hanging down temperature difference liquid-gas phase transition generator set and liquid-gas phase transition heat pump techniques, people seen again from normal-temperature water, draw heat energy generate electricity can success a thread dawn, the someone has applied for that relevant patent is (as application number: 200410097600 disclosed " utilizing the energy source technological scheme of heat pump and double fluid circulation generating equipment ").But this method with phase transformation heat pump techniques and phase transformation generation technology simple combination, analyzing from actual engineering level to become stand alone generating system.Usually the temperature difference of heat pump generation is about 40 ℃, and at this moment, the efficient of liquid-gas phase transition generator is extremely low, generally is no more than 20%.Under the situation of water-cooled, heat pump or cold pump performance coefficient are generally less than 5.0, then, the coefficient of performance * low temperature difference generating efficiency＜5.0 * 20%=100%, promptly the electric energy that sends of system self is less than the electric energy of autophage, so system can not set up.Even conversion efficiency is a little more than 20%, system does not have use value yet.
We find after deliberation, use two contrary Carnot's cycles of heat pump and cold pump simultaneously, just can make heat pump and cold pump individual system under the same temperature difference (as 40 ℃), do not reduce the coefficient of performance, and can produce two times or higher thermal gradient energy, according to the conversion efficiency of existing low temperature difference liquid-gas phase transition generator set under this temperature difference, just can produce a kind of generating system apparatus that can utilize heat energy in the water at normal temperature.
Summary of the invention:
The objective of the invention is under existing engineering level, propose a kind of technological scheme that thermal power transfer in the water at normal temperature is become the electric energy be convenient for people to use etc. technically.
One, about utilizing the basic principle of the heat energy power-generating in the water at normal temperature
People know, high again temperature if there is not the temperature difference, is impossible externally do work, and in fact thermal gradient energy is only the energy that can be used to do work.The process of heat pump or cold pump work is exactly the process that produces the temperature difference, and this process is not a conversion process of energy, be not subjected to the restriction of the energy conversion efficiency limit 100%, but be subjected to the restriction of contrary Carnot's cycle efficiency, the coefficient of performance is represented or be called to its efficient with the COP value, just be heating efficiency when heating, just be coefficient of refrigeration during refrigeration, it is to heat or the ratio of refrigerating capacity and input power.In the liquid-gas phase transition process, produce a large amount of heat of liquefactions when refrigerant or thermal medium liquefy under highpressure, and when lowpressure is vaporized, absorb a large amount of vaporization heat, make less electric energy can carry more heat energy, form higher thermal gradient energy.The heat pump water heater utilization of Shi Yonging is exactly this principle in a large number.
The application technology of present liquid-gas phase transition generator set is comparative maturity, and efficient is very high, its working principle is: thermal energy transfer is given the thermal source medium (cryogenic fluid) in the steaming plant (heat exchange/heating), the heat absorption of thermal source medium flashes to the vapour-liquid mixed phase vapor stream that has the hot pressing difference, enter decrease temperature and pressure expansion acting in the power engine, with thermal power transfer is mechanical power, drives generator for electricity generation; With oil hydraulic pump the condensed liquid heat source medium of acting is returned steaming plant, heat exchange/heating so moves in circles again.
Be a kind of desirable system schematic of utilizing the heat energy power-generating in the water at normal temperature shown in the accompanying drawing 1, at first auxiliary starting system provides electric power, allows the such heat pump with liquid-gas phase transition ability heat output; In the process of heating, heat pump absorbs heat in water; Thermal gradient energy between the heat energy of heat pump output and the water of cooling offers power generation system (promptly low temperature difference liquid-gas phase transition generator set) by heat conductor etc., after generator set runs well, external power is disconnected, an electric energy part that allows system send feeds back to heat pump and keeps its work, has more the electric power output of part; Heat energy in the water at normal temperature device that is used to generate electricity has just been realized so.System absorbs energy from water at normal temperature and is converted to the successful key of electric power output, is the electric energy of the electric energy that sends of power generation system greater than the whole system autophage.
Two, about utilizing the heat energy power-generating theory analysis in the water at normal temperature
(1) the heat pump temperature difference and coefficient of performance analysis thereof
The temperature difference that contrary Carnot's cycle forms is generally not high.Heat pump temperature difference t=output temperature one ambient temperature, and Δ t * COP has individual maximum value.In other words, the very high coefficient of performance just can not produce the high temperature difference; Otherwise producing the very high temperature difference just can not have the very high coefficient of performance.Particularly the condenser temperature of heat pump can not be too high, not only can reduce heating efficiency after temperature is too high, influences the working life of heat pump simultaneously.Why numerous the water-exit temperature of heat pump water heater product generally be up to 65 ℃, is to be 25 ℃ with average temperature of the whole year, and the best temperature difference is 40 ℃ and sets.
The heat pump utilization be heat energy in air (air-cooled), absorb by working medium promptly that airborne normal temperature thermal source heats, as the heating efficiency up 4.0 of the JKR series product of market sale.The water-cooled air-conditioning is when heating, and reality also is a heat pump, is that working medium absorbs the heat energy in the normal-temperature water.According to data: the air-cooled and coefficient of refrigeration water-cooled air-conditioning is respectively: its coefficient of refrigeration of SPLIT AIR-CONDITIONING SYSTEM (air-cooled) is lower, is generally 2.6～3.0; The coefficient of refrigeration of water-cooled unit is higher, generally greater than 5.0; System also produces the heat of same equivalent in refrigeration, and the heat that unit self power consumption produces is not easy to utilize, so actual effectively heating efficiency is approximately equal to coefficient of refrigeration, the temperature difference that air-conditioning produces is much smaller than 40 ℃.Through to the evaluation of above-mentioned aggregation of data: the water of normal temperature is as the thermal source of heat pump, and the heating efficiency when 40 ℃ of the temperature difference is about 5.0.In other words, it is electric to consume 1 degree, can produce to be equivalent to the heat energy that 5 degree electricity produce.
When conducting the thermal gradient energy of heat pump to the phase transformation generator set by heat conductor, because the influence of heat conductor self thermal resistance, the thermal gradient energy that arrives the phase transformation generator set will have certain loss, so the temperature difference is when 40 ℃ of left and right sides, and the effective heating efficiency of system is less than 5.0.
(2) about hanging down the internal efficiency analysis of temperature difference phase transformation generator set
For the heat energy power-generating unit of the low temperature difference, the conversion efficiency of vapour-liquid mixed phase vapor stream generator set is the highest, and particularly people improve its efficient after Bretton backheat technology (as in the accompanying drawing 2 45) is applied to vapour-liquid fluid-driven power generator group greatly.Data shows: the more existing enterprises of China produce this class liquid-gas phase transition generator set at present, and its single-machine capacity has kind more than ten from 100-1500kw; Its heat source temperature between 90 ℃ of 90-1 or heat source temperature be slightly less than under the situations such as 90 ℃, the generating internal efficiency can be up to 65-80% when 40-100% loads.
The high basic reason of above-mentioned vapour-liquid fluid-driven power generator group efficient is that system can be according to the work of thermomechanics triangle circulation theory, i.e. brayton cycle backheat application technology.Wherein the vaporization heat of considerable part and heat of liquefaction are cancelled out each other, and thermal loss is little, and efficient exceeds 60% than the Rankine cycle of no backheat.If but the temperature difference is too low, the conversion efficiency of generator set is very low.It is reported: the ocean thermal energy conversion unit with ammonia as cryogenic fluid, the existing small test power station of Japan, more comprehensive research has been done by the U.S., the conversion efficiency of system only has 6.8～9% during 20～27 ℃ of the low temperature difference, add that the TV university part of sending also will be used to draw water ... and 6.8～9% conversion efficiencies have been represented present international highest level, for 40 ℃ of left and right sides temperature difference, by being that linear relationship is calculated between the temperature difference and the efficient, its conversion efficiency is about 40 ℃ of ÷, 27 ℃ * 9% ≈ 13%, considers that so the non-linear factor influence also is difficult to make its conversion efficiency greater than 20%.
(3) to the judgement of the heat energy power-generating system that utilizes water at normal temperature shown in the accompanying drawing 1
For 40 ℃ of left and right sides temperature difference, the heating efficiency of heat pump * low temperature difference generating efficiency=5.0 * 13%=65%＜1.0, promptly system self electricity can be less than the electric energy of autophage, so system can not set up.Even conversion efficiency reaches 20%, the heating efficiency of heat pump * low temperature difference generating efficiency=5.0 * 20%=100%=1, or be a bit larger tham 1, system does not have use value yet.In addition, this system is when ambient temperature is low, and the conversion efficiency of heating efficiency and generator set all will reduce.Therefore, this system can not realize.
(4) about improving the basic method analysis of system's generating efficiency
The problem of attached system shown in Figure 1 is that the phase transformation generator set is too low in low temperature difference timeliness rate.Two kinds of solutions are generally arranged: the first improves the generator set conversion efficiency, but under the so low temperature difference, present generating efficiency is near limiting value, so the impossible raising of conversion efficiency is a lot.It two is the temperature difference that improve heat pump, but meanwhile heating efficiency has reduced, and the whole conversion efficiency of system does not improve.
In view of above-mentioned analysis, solution of the present invention is: use two pumps simultaneously, promptly one is used to heat, another is used for refrigeration, if the temperature difference of temperature and environment all is 40 ℃ during the heat pump system of setting hot and cold pump refrigeration, allow (temperature difference the is about 80 ℃) thermal gradient energy between hot and cold pump offer the phase transformation generator set, the phase transformation generator set can have higher generating internal efficiency so.Positive so-called " quantitative change to qualitative change ", such disruptive technology scheme, heat or coefficient of performance of refrigerating and help improving under the situation of this coefficient of performance not influencing, the temperature difference that allows contrary Carnot's cycle produce doubles, and makes the liquid-gas phase transition generator set can use Bretton backheat technology well.According to the relevant information in the above-mentioned vapour-liquid fluid-driven power generator group, select suitable low-temperature heat source medium, the generating internal efficiency is at least 65%.
System as shown in Figure 2, produced simultaneously heat can be utilized by heat pump again in cold pumping system process of refrigerastion, so the heating efficiency of heat pump will be much larger than 5.0.Mean value can be greater than 6.0 for its systematic function coefficient of conservative estimation (heat and freeze).The generating coefficient of whole system is:
η＞the temperature difference coefficient of performance * generating internal efficiency * system effectiveness (supposition 90%)=6.0 * 0.65 * 0.9=3.5, obviously system's generating efficiency has improved a lot.
(5) attached system shown in Figure 2 is utilized the feasibility analysis of the heat energy power-generating of water at normal temperature
The data of above-mentioned analysis are taken from the product introduction of two above enterprises of family substantially, and therefore, it has authenticity and operability; Generating coefficient η＞3.5 of whole system show: consumption 1 degree electricity, can send out 3.5 degree at least; After disconnecting auxiliary actuating apparatus, system feedback part electric energy uses for hot and cold pump group and correlation control unit, and total system does not need other electric power can continuous service, and can export a part of electric energy.The conversion coefficient of then exporting electric energy only is approximately: η is clean=and 3.5-1.0=2.5.
Here the data of not getting rid of analysis have the possibility that a little bias or some other X factor are not considered, even one times of deviation, the generating coefficient of system: η '=3.5 ÷ 2=1.75＞1.0 at least.Therefore native system can be used as the application of independent generator group fully.
Three, the technical problem that mainly solves of the present invention and the technological scheme of employing
1. pass through the thermal gradient energy generator of the hot and cold pump combination technique formation of employing liquid-gas phase transition.When the extraction transformation of energy becomes thermal gradient energy the water under normal temperature, do not reduce the coefficient of performance (COP), but make the temperature difference of output increase by one times, improved the thermal gradient energy conversion coefficient greatly.
2. constitute the liquid-gas phase transition cold and heat pump systems and the liquid-gas phase transition power generation system of thermal gradient energy generator,, the coefficient of performance of thermal gradient energy generator and the conversion efficiency of liquid-gas phase transition power generation system all are improved by the backheat technology of brayton cycle.
3. the heat that produces after the cold pumping system of liquid-gas phase transition freezes offers heat pump again through heat distribution pipeline and heats, and has further improved the average behavior coefficient of thermal gradient energy generator.
4. change according to the water temperature of Various Seasonal,, normal-temperature water is flowed into the sequencing conversion of cold pump and heat pump, but the output temperature of balance heat pump and cold pump then makes the cryogenic fluid of phase transformation generator set be operated in the optimum state by its switched system device.Reduced the influence of climatic change to systematic function.
5. just because of the employing of above-mentioned several key technologies, make system after starting by auxiliary power, the electric energy that system sends is much larger than the electric energy of system's autophage; After auxiliary power was disconnected, system did not only depend on the electric power continuous service that feeds back, and can also export a part of electric energy or power.

Embodiment:
The invention will be further described below in conjunction with accompanying drawing 2
A kind of generating system apparatus that utilizes heat energy in the water at normal temperature, system is made up of inlet and outlet system 1, the cold pumping system 2 of liquid-gas phase transition, liquid-gas phase transition heat pump 3, liquid-gas phase transition power generation system 4, temperature difference energy, heat conductor 51 and heat conductor 52, auxiliary power startup and output unit 6 and heat distribution pipeline 7, is characterized in: be made of the temperature difference generator of one group of cold pumping system 2 of liquid-gas phase transition with 3 combinations of liquid-gas phase transition heat pump at least.Wherein, the condenser 21 of the cold pumping system 2 of liquid-gas phase transition and liquid-gas phase transition heat pump 3 is connected through heat distribution pipeline 7.
In the thermodynamic system that constitutes the cold pumping system 2 of liquid-gas phase transition and liquid-gas phase transition heat pump 3 and liquid-gas phase transition power generation system 4, a regenerator 25, regenerator 35 and regenerator 45 are set at least respectively.
Workflow of the present invention is:
The cold pumping system 2 of liquid-gas phase transition is by water-cooling pattern the heat that condenser 21 produces to be taken away, allow vaporizer 23 produce a large amount of colds, compressor 22 and throttle valve 24 are basic elements of character that cold pumping system is realized contrary Carnot's cycle, regenerator 25 is that system allows and need after the refrigerant of preheating and the condensation to need the mutual heat-shift of refrigerant of cooling before the compression, to improve system's coefficient of refrigeration, for the cold pump under 40 ℃ of left and right sides temperature difference, effect is obvious.Liquid-gas phase transition heat pump 3 is by the hydro-thermal mode cold that vaporizer 31 produces to be taken away, allow condenser 33 produce a large amount of heats, compressor 32 and throttle valve 34 are basic elements of character that heat pump is realized contrary Carnot's cycle, the effect of regenerator 35 is the same, can obviously improve the heating efficiency of system.
In the liquid-gas phase transition power generation system 4, vaporizer 41 allows working medium obtain heat and forms the High Temperature High Pressure gas, liquifier 43 is to make the internal working medium gentle pressure drop of liquefying low, thereby make the internal motivation machine two ends of generator set 42 form draught head, the acting so that High Temperature High Pressure steam state working medium expands is that mechanical power drives generator for electricity generation with thermal power transfer.44 of liquid pump valves need to consume electric power seldom, just can deliver to the zone of high pressure to the liquid refrigerant of same molecular weight from low pressure area.The main effect of regenerator 45 is the heat that the origin of heat that absorbed when allowing the systematic working medium vaporization is emitted when it liquefy, and with the conversion efficiency of raising thermal gradient energy, effect is quite obvious.
In one embodiment of the present of invention, heat conductor 51 is that the circulation by media such as oils passes to liquifier 43 to the cold of vaporizer 23; Heat conductor 52 is that circulation by media such as oils is the heat transferred vaporizer 41 of condenser 33.
The effect of described heat distribution pipeline 7 be heat that condenser 21 is emitted by cooling water (temperature is higher than normal temperature) heat transferred vaporizer 31, be equivalent to the temperature difference of liquid-gas phase transition heat pump 3 has been reduced, thereby the raising heating capacity also is equivalent to the coefficient of performance that has improved the thermal gradient energy generator.
