[0030] An air suction fan 12 is installed on one side of the treatment box 1, and the air suction fan 12 is connected with the treatment box 1 through an air suction pipe 13.

[0031] In the above embodiment, the suction fan 12 sucks air into the treatment box 1 through the suction pipe 13, the oil gas enters the second connecting pipe 4 through the air inlet cover 7 and the air inlet pipe 6, and then enters the condenser 2, so that the components in the oil gas are condensed into liquid, and then the condensed liquid enters the treatment box 1 through the first connecting pipe 3 and the discharge cover 5, and then the oil liquid is filtered through the filter plate 9. The liquid oil can be filtered to remove impurities and improve the quality of the liquid oil. The filtered oil liquid flows to one side of the treatment box 1 through the inclined plate 27 to facilitate oil liquid discharge. Then the control valve 11 is opened, and the oil liquid is discharged through the liquid discharge pipe 10 to complete the recovery of the oil liquid for subsequent use.

[0032] Wherein, the filter screen 8 is provided, which can perform preliminary filtering when the oil gas enters, so that the equipment can work more efficiently, and the risk of blockage and damage is reduced.
