As a specific embodiment of the oil gas recovery processing device provided by the present invention, please refer to fig. 3 and fig. 4, further comprising: a heat conducting member 8, a heat exchange cover 9 and two sealing plates 10. A cavity for oil gas to circulate is arranged in the heat conducting piece 8, one end of the heat conducting piece is communicated with the oil gas port, and the other end of the heat conducting piece is communicated with the underground storage tank 7; the heat exchange cover 9 is covered on the heat conducting piece 8; the two sealing plates 10 are used for sealing with the heat exchange cover 9 to form a sealing body which is arranged outside the heat conducting piece 8 in an enclosing mode, one sealing plate 10 is communicated with the air outlet 5 of the vacuum pump 6, and the other sealing plate 10 is provided with a conveying opening. Because the vacuum pump 6 does work on the oil gas, the temperature of the oil gas rises, if the oil gas is directly introduced into the underground storage tank 7, the temperature of the underground storage tank 7 is high, and accidents are easily caused, so that a cooling device needs to be installed between the vacuum pump 6 and the underground storage tank 7, the traditional cooling device is air-cooled, and although the effect is high, the waste of certain resources is caused. And connect heat exchange cover 9 with the oil gas that vacuum pump 6 flowed out, and the oil gas that flows out from underground storage tank 7 flows into in the heat-conducting piece 8, because the inside diffusion cavity that is of chamber spare, the circulation volume of gas has been increased, heat exchange cover 9 is established to the outside cover of heat-conducting piece 8, and it is sealed through two closing plates 10, the high temperature oil gas that flows into heat exchange cover 9 through closing plate 10 carries out heat exchange with the oil gas from underground storage tank 7, thereby the temperature of discharging into the oil gas from vacuum pump 6 has been reduced, and the oil gas temperature that produces from underground storage tank 7 risees, thereby the contact efficiency with active carbon layer 4 has been strengthened, because whole journey all need not plus the energy, energy-concerving and environment-protective purpose has been reached, the oil gas that simultaneously passes through the heating can strengthen the adsorption effect with active carbon layer 4, further absorption efficiency has been improved.
As a specific embodiment of the oil gas recovery processing device provided by the present invention, the heat conducting member 8 is a copper member, and the copper member can improve heat conducting efficiency and improve heat transfer between oil gases.
As a specific embodiment of the oil gas recovery processing device provided by the present invention, please refer to fig. 7, which further includes: a heat conducting box 19 and a U-shaped tube 21. The heat conduction box 19 is buried at the ground bottom, and a heat conductor 20 is contained in the heat conduction box; one end of the U-shaped pipe 21 is communicated with the conveying port, the other end of the U-shaped pipe 21 is communicated with the underground storage tank 7, and adsorption oil is placed in the U-shaped pipe 21, so that impurities in oil gas are adsorbed; the heat in the oil gas is conducted to the heat conductor 20 through the U-shaped pipe 21, and the heat conductor 20 conducts the heat to the soil through the heat conduction box 19. In order to further reduce the oil gas from vacuum pump 6 exhaust, can bury heat conduction box 19 underground, and hold heat conductor 20 in heat conduction box 19, add adsorption oil in U type pipe 21, the dust that the active carbon produced or filter inadequately, it is difficult to clear up just after discharging into underground storage tank 7, and let in adsorption oil with oil gas in, filter the impurity in the oil gas through oil, thereby the cleanness that gets into underground storage tank 7 oil gas has been guaranteed, and because soil temperature is lower, the high temperature of oil gas passes through U type pipe 21 and transmits to heat conductor 20, heat conductor 20 is again with heat transfer to heat conduction box 19 finally give off to in the soil, because this process need not the external energy, and the cooling effect is better, and the filter capacity is stronger, thereby the cleanliness factor of oil gas has been guaranteed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
