The air condensed in the left cavity will flow through the inner cavity of the frame 24. Through the design of the stainless steel woven mesh 282, the oil in the air can be intercepted by physical means, improving the oil separation effect, reducing the filtration load of the subsequent activated carbon, and extending the service life of the activated carbon.

The rubber sleeve 29 is fixedly connected to the inner wall of the final stage condenser 21 near the top. During the intervals of operation, the vibration motor 27 can be controlled to work, driving the stainless steel woven mesh 282 to vibrate, thereby shaking the oil intercepted on the stainless steel woven mesh 282 to the bottom of the inner cavity of the final stage condenser 21, facilitating subsequent collection.

The condensation pipe 23 is an existing device with circulating coolant inside. The condensation pipe 23 can cool the oil and gas, promoting oil condensation. The condensed oil will be temporarily stored at the bottom of the inner cavity of the final stage condenser tank 21. By opening the control recovery valve 215, the oil can be discharged. The air condensed in the left cavity of the final stage condenser tank 21 will flow through the inner cavity of the frame 24 and pass through the stainless steel braided... The design of mesh 282 can physically intercept oil in the air, improving the oil separation effect. During the intervals of operation, the vibration motor 27 can be controlled to work, driving the stainless steel woven mesh 282 to vibrate, thereby shaking the oil intercepted on the stainless steel woven mesh 282 to the bottom of the inner cavity of the final stage condenser tank 21. The air output from the exhaust pipe 214 will enter the inner cavity of the riser 31. Through the activated carbon inside the riser 31, the small amount of VOCs contained in the air can be adsorbed, which helps the exhaust gas to meet the standards.
