At the same time, there are odors and dust in the exhaust gas, which cause certain harm to the body. At present, the exhaust gas absorption generally adopts one-stage or multi-stage falling film absorption tower, which can absorb harmful substances and dust in the exhaust gas.
[0003] The device absorbs and utilizes the tail gas in the chemical production process, but when it absorbs to a certain extent, the internal mesh will adhere to a lot of dust particles of the tail gas, causing blockage, thereby affecting the subsequent continuous production, and it is difficult to ensure the normal absorption efficiency and effect. The absorption tower needs to be disassembled and cleaned regularly. However, manual cleaning of the inside of the absorption tower is time-consuming and laborious.
