Abstract
The invention relates to a novel oil gas recovery device, comprising an anti-explosion compressor, an oil storage tank, a primary refrigeration system and a secondary refrigeration system. The anti-explosion compressor is added before oil gas condensation, oil gas pressure is improved, oil gas saturation temperature is increased, and the primary evaporative condenser of the primary refrigeration system is an evaporator of the primary refrigeration system and a condenser of the secondary refrigeration system and is used for cooling compressed oil gas and condensing refrigerating fluid methane vapour into liquid; and the evaporator of the secondary refrigeration system condenses and recovers oil gas into the oil storage tank. The original three-stage overlaid type refrigeration is simplified to be secondary two-stage overlaid type refrigeration, device is effectively simplified, oil gas condensation temperature can be increased to about minus 115 DEG C from about minus 170 DEG C, stability is good, and equipment investment, operating cost and investment cost are reduced.

Description of drawings
Fig. 1 is a device for recovering oil and gas structural representation block diagram of the present invention.
The specific embodiment
The device for recovering oil and gas structural representation comprises explosion-proof compressor 1, one-level evaporative condenser 2, a stage compressor 3, first-stage condenser 4, one-level flow regulating valve 5, secondary evaporimeter 6, split compressor 7, secondary condenser 8, two-step throttle valve 9, petrol storage tank 10 as shown in Figure 1.Collect the one-level evaporative condenser that enters first order refrigeration system after good oil gas boosts through explosion-proof compressor 1 earlier, enter the secondary evaporimeter 6 of second stage refrigeration system after the preliminary cooling, enter petrol storage tank 10 after oil gas condenses.Whole refrigeration system is the cascade refrigeration system, first order refrigerant is an ethene, and second stage refrigerant is a methane, enters first-stage condenser 4 behind the ethene process one-level refrigerating compressor 3, after one-level flow regulating valve 5, enter one-level evaporative condenser 2 cooling oil gas and methane then; Methane is entering secondary condenser 8 through behind the split compressor 7, and the one-level evaporative condenser 2 that enters first order refrigeration system more further cools off, and passes through two-step throttle valve 9 then, enters the purpose that secondary evaporimeter 6 and oil gas heat exchange reach the oil gas that condenses at last.
Install explosion-proof compressor 1 before the oil gas condensation additional, improve oil-air pressure, rising oil gas saturation temperature.What oil gas adopted in explosion-proof compressor boosts process is polytropic compression, by explosion-proof compressor outside the radiating gill or the water jacket of cooling cooling is housed, and makes oil gas be compressed to but non-detonating of higher pressure, thus easier condensation.
One-level evaporative condenser 2 be the evaporator of one-level refrigeration system be again the condenser of two-stage system cooling system, be used to cool off the oil gas after overdraft and be liquid the refrigerant methane devaporation of two-stage system cooling system; Secondary evaporimeter 6 reclaims the oil gas condensation and enters petrol storage tank 10 as the evaporator of two-stage system cooling system.Regenerative apparatus is reduced to the secondary cascade refrigeration by three grades of original cascade refrigerations.Corresponding cost of investment and the over-the-road expense of having reduced is for the engineering practical application provides technical basis.
