[0002] Waste gas collection is the first step in waste gas treatment. The design of the gas collection device is not only related to the waste gas collection efficiency and unorganized emissions, but also affects the operation and maintenance of production equipment and the layout changes of production equipment and production workshops. At present, most gas collection devices are installed in open and fixed types. The defect of the open type is that the gas collection air volume must be increased to ensure the gas collection efficiency, which causes the subsequent treatment equipment to have a large air volume load. Once the gas collection air volume is too small, the gas collection efficiency will drop significantly and the unorganized emissions will increase sharply. Fixed installation interferes with the operation and maintenance of production equipment on the one hand, and cannot adapt to the adjustment of production equipment or production workshop layout on the other hand.
