The evaporator tube 442 is cooled in the heat exchange tank 441 by the compressor 41, and the temperature inside the heat exchange tank 441 is lowered. After the gas enters the heat exchange tank 441 in the low-temperature environment, oil gas in the gas is cooled and condensed to form oil liquid, and the oil liquid is output from the liquid outlet 403 to the flow channel recovery pipe 3. And the oil gas content of the gas after the condensation treatment is greatly reduced, so that the gas exhausted from the exhaust pipe 2 can be cleaner, and the requirement of environmental protection can be met.

Further, in order to improve the condensing efficiency, the evaporator 44 is disposed in the heat exchanging tank 441 in a serpentine coil. The evaporation tube 442 is arranged in the heat exchange tank body 441 in a winding and bending mode to increase the contact heat exchange area between the evaporation tube 442 and the gas, and further more effectively perform condensation treatment on oil gas in the gas.
