Abstract

Disclosed in the present invention is a waste gas treatment system, at least comprising a fume treatment system and an oil mist treatment system. The fume treatment system comprises a gas collection hood, fume ductwork, a cyclone dust collector, a bag filter and a first fan, wherein the gas collection hood, which is used for collecting fumes, is arranged above the area where fumes / dust are generated; the gas collection hood is connected to the cyclone dust collector via the fume ductwork, the cyclone dust collector, the bag filter and the first fan are connected in sequence, and the first fan is connected to a first exhaust stack. The oil mist treatment system comprises an oil mist collection hood, oil mist ductwork, a pneumatic cyclone tower, an electrostatic adsorption device, an activated carbon adsorption device, and a second fan, wherein the oil mist collection hood is connected to the pneumatic cyclone tower via the oil mist ductwork, the pneumatic cyclone tower, the electrostatic adsorption device, the activated carbon adsorption device, and the second fan are connected in sequence, and the second fan is connected to a second exhaust stack. The present invention enables effective removal of various waste gases generated during enterprise production and processing.
