2 is a view showing the structure of a vapor-liquid-recovery tower of a vapor-liquid-liquid recovery apparatus according to the present invention.
3 is an enlarged view of part A of Fig.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

Referring to FIG. 1, a separate type vapor recovery apparatus using a cold source of an air conditioning refrigerator according to the present invention is provided for cooling and recovering vapor generated in the oil storage tank 100.

The oil storage tank 100 is generally installed in a basement such as a gas station, and receives and stores oil from an oil tanker or the like. The oil stored in the oil storage tank 100 may be, for example, gasoline, light oil or kerosene, and such oil may be volatile and generate vapor. Generally, the oil vapor generated in the oil storage tank 100 is discharged to the outside through the oil exhaust pipe 110 installed in the oil storage tank 100.

The apparatus for recovering vapor of vapor according to the present invention includes a refrigerator for air conditioning and a vapor-liquid-recovery tower 300 located apart from the refrigerator. That is, the present invention includes a vapor liquefaction recovery tower 300 disposed adjacent to the oil storage tank 100 so that the vapor is introduced from the remotely located refrigerator 200 and the oil storage tank 100.

The air conditioning refrigerator 200 includes a compressor, a condenser, an expansion valve, and an evaporator, and includes an apparatus having a refrigeration cycle capable of generating cooling energy by circulation of refrigerant. The air conditioner refrigerator 200 according to the present invention includes a cooler generally referred to as an air conditioner system. According to the present invention, the air conditioner refrigerator 200 includes a compressor and a condenser, and is connected to the vapor- And various devices capable of generating cooling energy by circulation of the refrigerant.

According to the embodiment of the present invention, the refrigerator may be a cooling system already installed in a gas station or the like, that is, an air conditioning system 200. In a place where the gas such as a gas station is handled, an office air conditioner 200, which is generally referred to as an air conditioner system 200, is installed in an office building 1 for a worker. The office building 1 is designed so as to ensure stability by being positioned apart from the oil discharge space of the oil storage tank 100.

Referring to FIG. 1, the air conditioner system 200 includes an indoor unit 210 installed in an office building 1 and an outdoor unit 220 installed outside the office building 1.

The outdoor unit 220 of the air conditioning system 200 includes a compressor 221 for compressing a refrigerant and a condenser 222 for dissolving and liquefying the compressed refrigerant by exchanging heat with outdoor air. An expansion valve 211 for reducing the pressure of the high-pressure refrigerant to a low pressure, and an evaporator 212 for vaporizing the low-pressure refrigerant to freeze by heat absorption.

The vaporizing and recovering apparatus according to the present invention uses the outdoor unit 200 including the compressor 221 and the condenser 222 of the air conditioning system 200 as a freezer to reduce the overall installation cost of the air conditioning system and the liquefying and recovering apparatus . Generally, the vapor-liquid separation and recovery device is not a device that is operated at all times. For example, it is known that the vapor-liquid separation and recovery device has an operation time of about one day or two days and about 30 minutes in a gas station. Therefore, if the refrigerator including the compressor 221 and the condenser 222 is installed and operated only for the vapor liquefaction recovery operation, the efficiency of installation and operation is low. However, if the refrigerator can also be used for the air conditioning system, the installation cost can be reduced because the refrigerator can be operated for cooling normally at a normal time and temporarily used for vapor recovery.

1, a pipe for purifying the refrigerant is formed between the indoor unit 210 and the outdoor unit 220, and a pipe between the condenser 222 of the outdoor unit 220 and the expansion valve 211 of the indoor unit 210 is provided between the indoor unit 210 and the outdoor unit 220. [ An inlet pipe 230 for supplying refrigerant to the vaporized liquid recovery tower 300 is connected to the piping of the indoor unit 210 and the piping of the indoor unit 210 and the compressor 221 of the outdoor unit 220 An outflow pipe 240 for discharging the refrigerant from the vapor-liquid-recovery tower 300 to the compressor 221 is connected. The piping between the indoor unit 210 and the outdoor unit 220 can be selectively controlled so that the refrigerant is circulated between the outdoor unit 220 and the vapor liquefaction recovery tower 300 or circulated between the indoor unit 210 and the outdoor unit 220. [ And the inlet pipe 230 and the outlet pipe 240 are provided with a valve system by valves 250 and controlled by the control unit 400. [

The control unit 400 controls the refrigerant flow so that the refrigerant is circulated between the outdoor unit 220 and the vapor-liquid-liquid recovery tower 300. At this time, the high-pressure refrigerant generated from the outdoor unit 220 is stored in the oil storage And then flows into the tank 100 to exchange heat with the vapor discharged from the oil storage tank 100 to liquefy the vapor. That is, the air conditioning system 200 normally performs cooling in the office building 10 such as a gas station, and then supplies the refrigerant generated in the outdoor unit 220 to the oil vapor discharged from the oil storage tank 100 Thereby performing liquefaction and recovery of the vapor.

3, the pipeline to which the outdoor unit 220 of the air conditioning system 200 and the liquefied gas recovery tower 300 are connected, that is, the condenser 222 of the outdoor unit 220, And an outlet pipe 240 through which the low-pressure refrigerant circulating from the vapor-liquid-collecting recovery tower 300 to the compressor 221 flows, are connected in the form of a double pipe. That is, the outlet pipe 240 is formed in a double pipe shape in which the inlet pipe 230 extends into the outlet pipe 240, and the outlet pipe 240 is formed to surround the inlet pipe 230 from the outside of the inlet pipe 230.

Since the outer pipe 220 and the oil pipe 230 are formed as a pipe in the form of a double pipe of the outlet pipe 240, the connection between the outdoor device 220 and the oil pump liquefaction and recovery tower 300 can be made as one pipe.

1, the air conditioner system 200 according to the present invention includes a compressor 221 for compressing a refrigerant, and a condenser 222 for dissolving and liquefying the compressed refrigerant through heat exchange with the outside air And the outdoor unit 220. The refrigerant generated from the outdoor unit 220 is heat-exchanged with the vapor discharged from the oil storage tank 100 to liquefy the vapor. Since it is already remotely located from the outdoor unit 220 of the air conditioner system 200 using electricity which is an explosion factor of the vapor flowing into the vapor-liquid-liquid recovery tower 300, it is not necessary to install a separate explosion-proof structure. That is, according to the present invention, the cost for forming an explosion-proof structure is reduced.

Referring to FIGS. 1 and 2, according to the present invention, the vapor-liquid-recovery tower 300 is capable of recovering liquefied vapor by the heat of evaporation of the refrigerant, which is absorbed by heat exchange with the vapor of the high-pressure refrigerant generated from the outdoor unit 220 .

A plurality of cooling fin modules 310 are installed in the vapor vapor-liquid recovery tower 300 in the height direction. That is, the cooling fin module 310 may be separated from the cooling fin module 310, and four cooling fin modules 310 may be provided.

The cooling pin module 310 is installed on a plane intersecting with the height direction of the refrigerant induction pipe to which the refrigerant supplied from the condenser 222 of the outdoor unit 220 is supplied and the cooling fin 311 is installed on the refrigerant induction pipe The cooling pin module 310 is configured such that the vapor rising through the through hole 313 between the refrigerant induction pipe and the cooling fin 312 is cooled through heat exchange. That is, the through hole 313 of the cooling fin module 310 becomes a rising path of the vapor.

According to the present invention, the inflow pipe 230 through which the refrigerant is supplied from the condenser 222 of the outdoor unit 220 to the vapor-liquid storage and recovery tower 300 is branched and connected to the cooling pin module 310, A flow regulated expansion valve 340 is installed in the branch pipe 231 of the inflow pipe that supplies the refrigerant to the refrigerant pipe 310. Each of the flow rate regulating expansion valves 340 is connected to each of the cooling fin modules 310 and functions to expand and expand the high pressure refrigerant through the cooling fin module 310 to facilitate evaporation. In addition, the flow regulated expansion valve 340 allows the flow rate of the refrigerant supplied to each cooling fin module 310 to be adjusted. The flow regulated expansion valve 340 may be formed by a combination of a flow regulating valve and an expansion valve, or the expansion valve may be configured to have a flow regulating function. That is, the flow rate regulating expansion valve 340 is disposed on the refrigerant inflow side of the cooling fin module 310 to allow the flow rate to be regulated while reducing the pressure.

Since the refrigerant flow rate is controlled by each flow control expansion valve 340, each cooling fin module 310 is configured to be able to regulate energy absorbed from the vapor, that is, cooling energy for each cooling fin module 310. That is, as the flow rate of refrigerant supplied to the cooling fin module 310 increases, the supplied cooling energy increases, and as the flow rate of the refrigerant decreases, the supplied cooling energy decreases.

According to the present invention, the coolant flow rate is regulated by the flow rate regulating expansion valve 340 such that the cooling energy provided by the cooling fin module 310 is reduced as the cooler pin module 310 is positioned lower. In this way, it is possible to control the temperature in the position corresponding to the position of each cooling fin module 310 inside the vapor-liquid-recovery tower.

The vapor contains air, moisture and vaporized oil. When a large amount of cooling energy is supplied from the cooling pin module 310 located at the lower end for liquefaction of the vapor, the moisture in the vapor is frozen in the lower cooling pin module 310 and is supplied to the through hole 313 of the lower cooling pin module 310, And the rising airflow of the vapor is blocked, which causes the stability of the vapor recovery tower.

Therefore, according to the present invention, the flow rate control valve 340 installed in the lower part of the vapor-liquid-liquid recovery tower 300 reduces the opening amount of the refrigerant to be supplied from the flow rate control valve 340 installed in the upper part, The temperature is adjusted to be gradually lowered at the position of each cooling fin module 310 of the tower 300. For example, in the cooling pin module 310 located at the bottom, the ambient temperature is formed at a lower temperature than the freezing point, so that moisture in the vapor is condensed and condensed so as to be dropped. Since the moisture in the vapor is gradually removed from the lower part to the upper part, even if the cooling pin module 310 located at the upper part provides cryogenic cooling energy for liquefying the oil in the vapor, do. According to the present invention, by controlling the cooling energy supplied by varying the flow rate of the coolant depending on the position of the cooling fin module 310, that is, the heat taken away from the vapor, the cooling pin module 310 of the vapor- Can be controlled. To this end, each cooling pin module 310 may further include a temperature sensor.

According to the present invention, the through hole 313 of the cooling fin module 310 gradually decreases toward the upper part of the cooling fin module 310. This is because there is less fear of freezing as it goes to the upper part of the vapor-liquid-liquid recovery tower 300 and the contact density between the cooling-fin module 310 and the vapor is increased to further lower the cooling temperature so as to further improve the liquefaction performance. The refrigerant passing through each cooling fin module 310 evaporates and combines while absorbing the heat of the vapor, and is transferred to the compressor 221 of the outdoor unit 220 through the outflow pipe 240.

The refrigerant flowing into the vapor-liquid-recovery-recovery tower 300 is vaporized while passing through the cooling-fin module 310, and takes heat as much as the heat of vaporization, thereby cooling and liquefying the vapor passing through the cooling-fin module 310. The refrigerant passing through the cooling fin module 310 is combined and delivered to the compressor 221 of the outdoor unit 220 through the outlet pipe 240 and is again liquefied and circulated by the compressor 221 of the outdoor unit 220.

A water-oil separator 350 is formed at the lower end of the vapor-liquid-recovery tower 300. The oil water separating unit 350 is a place where water and oil which are liquefied in the cooling fin module 310 collect and which are separated into oil and moisture using a difference in specific gravity between oil and water. The oil water separating unit 350 includes a oil outlet 352 through which the oil separated from the oil vapor is discharged and a water outlet 353 through which moisture separated from the oil vapor is discharged. And the water is discharged through the water outlet 353 provided at the lower part. The oil discharged to the oil outlet 352 is collected and stored in the oil storage tank 100.

The air with the oil and moisture removed through the vapor recovery ladle 300 is discharged to the outside air through the air discharge port 354 installed in the upper part of the vapor liquid recovery and recovery tower 300.

An adsorbent 320 for adsorbing and removing moisture and oil remaining in the air through the cooling fin module 310 may be installed on the inner upper part of the vapor recovery ladle 300.

The air discharged through the air discharge port 354 flows into the energy recovery chamber 355 and is discharged from the oil storage tank 100 through the oil discharge pipe 110 and is discharged through the oil supply pipe 130, And may be configured to precool the vapor flowing into the recovery tower 300 in the energy recovery chamber 355. To this end, the vapor supply pipe 130 is connected to the lower portion of the vapor-liquid collection tower 300 via the energy recovery chamber 355. The vapor liquefaction recovery tower 300 provides cooling energy to recover moisture and oil from the vapor, so that the purified air is discharged to a low temperature. Energy efficiency is improved by recovering the cooling energy possessed by air discharged to the outside air through the energy recovery chamber 355.

A distribution pipe 120 is installed in the oil exhaust pipe 110 through which the oil vapor is discharged from the oil storage tank 100 so that the oil vapor discharged from the oil storage tank 100 passes through the oil recovery and recovery tower 300, And can be discharged directly to the outside air through the piping 120. Such a distribution pipe 120 is a stabilizing device that functions to prevent explosion by forcibly discharging the oil vapor to the outside when an overpressure is formed in the oil storage tank 100 so as to compromise safety and there is a risk of explosion .

The control unit 400 is connected to the valves 250 and the flow rate regulating expansion valve 340 to control the refrigerant circulation between the outdoor unit 220 of the airconditioning system 200 and the vaporized liquid recovery and recovery tower 300, And controls the flow rate of refrigerant supplied to each of the cooling pin modules 310. The control unit 400 may function together with the control unit of the air conditioning system 200 or may be connected to the control unit of the air conditioning system 200 to selectively operate the vapor recovery and recovery system and the air conditioning system.

Hereinafter, the operation of the vapor-liquid separation and recovery apparatus according to the embodiment of the present invention will be described.

For example, when a certain amount of time has elapsed after the amount of oil tankers loaded with the oil in the gas station has stored the oil in the oil storage tank 100 of the gas station, overpressure due to the oil vapor occurs in the oil storage tank 100.

The control unit 400 controls the valves 250 for controlling the circulation path of the refrigerant by the signal of the sensing unit for detecting the occurrence of the overpressure to circulate the refrigerant between the outdoor unit 220 and the vapor- . At this time, the indoor unit 210 is temporarily stopped. The outdoor unit 220 of the remotely located air conditioner system 200 is operated to compress the refrigerant at high temperature and high pressure in the compressor 221 and heat the refrigerant by heat exchange with the outside air at the condenser 222, And is circulated to the compressor 221 of the outdoor unit 220 via the cooling fin module 310. The compressor 300 is connected to the evaporator 300 through the cooling fan module 310,

At this time, an inflow pipe 230 through which the high temperature high-pressure refrigerant supplied from the condenser 222 of the outdoor unit 220 flows to the vapor-liquid-liquid recovery tower 300 and the air- The low temperature low-pressure refrigerant flows through the outflow pipe 240 in the form of a double pipe so that the cooling oil vapor liquefaction performance can be improved through heat exchange between the inflow pipe 230 and the outflow pipe 240.

The vapor of the predetermined pressure generated in the oil storage tank 100 flows into the vapor-liquid recovery tower 300 through the vapor discharge pipe 110 and the vapor supply pipe 130. The vapor is operated to discharge to the atmosphere only when the pressure is set and the pressure is at risk of explosion.

The vapor is composed of moisture, oil gas and air.

The vapor flowing into the vapor-liquid-recovery tower 300 flows upward through the cooling-fin module 310 and exchanges heat with the refrigerant. The liquefied vapor inside the vapor-liquid-recovery-recovery tower 300 condenses on the surface of the cooling-fin module 310 and flows down to the oil-water separator 350.

The water in the vapor is also liquefied while passing through the cooling fin module 310 and flows down to the oil water separator 350. The flow rate of the refrigerant supplied to each of the cooling pin modules 310 in the vapor-liquid condensing and recovering tower 300 is controlled individually, and the flow rate of the refrigerant supplied to the cooling pin modules 310 located in the lower portion is controlled to be relatively small. Type expansion valve 340 is controlled. In view of the rising path of the vapor, the temperature gradually falls inside the vapor-liquid-recovery tower 300, and the cooling-pin module 310 located at the lowermost part provides cooling energy at a temperature at which freezing of water can be prevented So that water can be liquefied while preventing freezing of water. The cooling fan module 310 located at the lower end raises the rough vapors to a state in which the moisture therein is removed to a certain degree, so that even if the lower cooling module 310 provides the lower cooling energy, Can be prevented from clogging.

The air in the vapor is discharged to the outside through the air outlet 354 and is supplied to the energy recovery chamber 355 to precool the vapor flowing into the vapor recovery ladle recovery tower 300 to improve the vapor liquefaction efficiency.

At this time, the refrigerant passes through the cooling fin module 320 and takes heat from the vapor and is vaporized. The vaporized refrigerant is again liquefied and circulated by the compressor 221.

The oil flowing into the oil water separating unit 350 is recovered to the oil storage tank 100 through the oil outlet 352 and the moisture is discharged to the outside through the water outlet 353.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It should be understood that various modifications made by the person skilled in the art are also within the scope of protection of the present invention.
