[0002] Oily waste gas is a common source of pollution in chemical fiber plants, refineries, chemical plants, oil production plants, paint plants, and enameled wire plants. Its composition is complex and difficult to treat. Direct discharge without treatment can severely harm environmental quality. Activated carbon, as an adsorbent, is commonly used in high-volume, low-concentration VOC treatment. Because activated carbon releases oily waste gas during desorption, conventional degreasers utilize sedimentation degreasing, which imposes certain wind speed requirements. Excessively high wind speeds prevent effective oil removal, leading to significant limitations.

[0003] Therefore, the market urgently needs to develop a mechanical oil removal device for processing desorbed waste gas to solve the above-mentioned technical problems. Utility Model Content
