Description

{RECOVERY APPARATUS OF OIL VAPOR} FIELD OF THE INVENTION [0001]

The present invention relates to a vapor liquefaction apparatus using metering and mist injection during the unloading operation and more specifically, collecting vapor generated when gasoline unloaded from a gas station is stored in a tank, and discharging it in the form of mist together with cold cooling water And more particularly, to a vapor liquefaction apparatus using metering and mist injection during the unloading operation, which causes the vapor to condense back to gasoline.

Generally, the oil supply to the oil storage tank embedded in the underground of the gas station or the oil reservoir is made by the tanker, and a large amount of the oil vapor is generated inside the tank when the oil is loaded.

The vapor contains toxic substances harmful to the human body, that is, benzene, toluene, xylene, ethylene and the like, which causes air pollution, so that atmospheric emissions are strictly restricted.

Therefore, the air containing the vapor should be discharged into the atmosphere with the vapor removed by using a separate treatment device

There have been developed various devices for preventing the release of vapor in the air and liquefying it to enable recovery of the vapor.

1 is a view showing a configuration of such a vapor recovery device disclosed in Korean Patent Publication No. 10-1521721.

Referring to FIG. 1, the apparatus for recovering vapor in the first embodiment of the present invention has a structure in which the vapor generated in the oil tank 1 is drawn out by the blower 2 to be introduced into the first cooling chamber 3, The water vapor is removed by cooling and dehumidifying, and some oil is liquefied. The primary cooling and dehumidifying vapor in the first cooling chamber 3 flows into the second cooling chamber 7 and is secondarily cooled. The oil contained in the vapor is condensed and separated in the cryogenic cooling state. The water and the oil discharged from the first and second cooling chambers 3 and 7 are separated from each other by the oil separator 6 so that the oil is returned to the oil tank 1 again.

In the above-described conventional vapor recovery apparatus, the first and second cooling chambers 3 and 7 are provided in the first and second cooling chambers 3 and 7 so as to increase the recovery efficiency of the vapor. Cooling system (4, 5) must be provided, which increases the overall equipment and consumes a relatively large amount of energy.

Therefore, it is necessary to develop a configuration capable of increasing the recovery efficiency of the vapor even if the size of the facility is reduced by providing a single cooling system.

As shown in FIG. 2, the present invention includes a simple tank 100 for collecting gasoline unloaded from a tank lorry, and an underground storage tank 200 for storing gasoline introduced from the simplified tank 100.

The simple tank 100 is provided with a gas collecting portion 10 for collecting gasoline to be unloaded on the upper side and a gas storage portion 10 for storing gasoline discharged from the gas collecting portion 10, A liquefying device 30 for liquefying the vapor generated in the storage tank 200 and disposed in the oil collecting part 10; And an oil water separator 40 separating the liquefied vapor introduced from the oil separator 40 into gasoline and water.

The oil collecting unit 10 includes an inlet pipe 11 formed at a side surface to allow gasoline to be unloaded from the oil tanker to flow inwardly and a connecting pipe 11 located at a bottom surface of the oil collecting unit and connected to a transfer pipe 20 And includes a first outlet (12) and a second outlet (13).

The bottom of the oil collecting part 10 is tapered in the direction of the first discharge port 12 so that the volatiles flowing through the inflow pipe 11 can be transported in the direction of the transfer pipe 20. A droplet is formed on the upper surface of the first outlet 12 to prevent the occurrence of a whirl due to the volatiles flowing into the transfer pipe 20 and a meter 222 formed on one side of the transfer pipe 20 Make accurate weighing possible.

The first discharge port 12 and the transfer pipe 20 can be located on the same line and one end of the transfer pipe 20 is formed in a funnel shape so that a large amount of gasoline can be injected into the transfer pipe 20 So that it is possible to shorten the time for which the gasoline stays in the oil collecting unit 10 and to prevent the liquefier 30 located in the oil collecting unit 10 from being trapped in the collected gasoline.

The transfer pipe 20 is located below the oil collecting unit 10 and is connected to the first transfer pipe 21, the second transfer pipe 22 and the third transfer pipe 23 continuously, So that it can flow into the storage tank 200 which will be described later without a separate pump.

The first transfer pipe 21 has a large upper diameter and a narrower lower diameter and is formed in the form of a funnel. Since the space on the upper side is formed to be wide, when the flow rate is controlled by the solenoid valve 221 described later, So that it can be prevented from flowing back into the oil collecting part (10).

A thermometer 211 and a pressure gauge 212 are provided on one side of the first transfer pipe 21 to measure the temperature and pressure of the gasoline flowing in from the oil collecting unit 10, 22 so as to adjust the amount of gasoline to be transferred.

The second conveyance pipe 22 is connected to one end of the first conveyance pipe 21 and a solenoid valve 221 and a meter 222 are formed on the inner side so that the amount of the gasoline to be transferred can be controlled and metered accurately .

The third transfer pipe (23) is connected to the other end of the second transfer pipe (22) and can transfer the gasoline into the storage tank (200). The third transfer pipe 23 is connected to the vapor discharge pipe 34 of the liquefier 30 to allow the remaining amount of the vapor generated from the liquefaction device 30 to be introduced therein.

Therefore, the gasoline unloaded from the oil tanker carries into the oil collecting unit 10 through the inflow pipe 11, and the inflow gasoline flows into the transfer pipe 20 through the first discharge port 12, So that it can be transported into the storage tank 200 where it is installed. The gasoline transported according to the above flow is installed with a thermometer and a meter to measure the amount of oil unloaded by the temperature conversion method (Kg), and the oil temperature, the specific gravity flow rate, .

As described above, the gasoline introduced into the storage tank 200 generates the vapor, and the vapor can be introduced into the liquefier 30 by the bead opportunity water pipe 211, and adsorbed with the introduced vapor and water So that it can be reduced to gasoline.

The liquefier 30 includes a flow pipe 31 for introducing the vapor generated in the storage tank, a mist generator 32 positioned at one side of the flow pipe 31 and injecting mist-like water, A remaining amount of water vapor recovery pipe 33 installed at one end of the flow pipe 31 to recover the remaining amount of the residual vapor and a drain pipe 33 located at one side of the remaining amount water vapor recovery pipe 33 and discharging the remaining amount of the vapor in the storage tank And a vapor discharge pipe (34).

The liquefier 30 is located on the upper side of the simple tank 100 and can be located inside the oil collecting part 10.

The flow pipe 31 is formed in a tubular shape and is bent upward and downward so that the moving distance of the vapor is long so that the pressure and the temperature included in the moving vapor can be lowered. Inside the flow pipe 31, 311 are formed on the upper surface of the flow pipe 31 and an injection device 312 is formed in the upper bending section of the flow pipe 31.

The mixture of water and vapor can be collected in the lower bending section of the flow pipe 31 and can be introduced into the oil water separator 40 through the mixture discharge pipe 313 (see FIG. 4).

A filter 311 is formed on the inside of the flow pipe 31 in the same direction as the flow pipe 31 so that water and vapor can be adsorbed by the rotation of the filter ).

At this time, the mist generating unit 32 discharges only water from the water and gasoline separated from the oil water separating unit 40 described later, and draws up water through the motor 321 formed at one side, (See Fig. 6). As described above, since the water adsorbed in the vapor is not discharged to the outside but reused, it has an effect of reducing environmental pollution.

The storage tank 200 means a tank in which oil vapor is generated, such as a gasoline storage tank used in a gas station or a volatile solvent tank used in a chemical plant.
