After the organic waste gas is filtered in sequence by the coarse filter element 21 and the fine filter element 22, the filtered organic waste gas will enter the air inlet cavity 4 through the air inlet 13. When the organic waste gas enters the inlet When the organic waste gas is inside the air cavity 4, it will enter the circulation cavity 6 through the copper tube 12, and enter the air outlet cavity 7 through the circulation cavity 6 and the copper tube 12, and then be discharged from the air outlet 14 to the external air outlet pipe through the air outlet cavity 7, so that the organic waste gas circulates in the recovery tank 3 through the copper tube 12.
