[0002] The working principle of an exhaust gas treatment tower is mainly to separate, transform, or remove harmful substances in exhaust gas through physical, chemical, or biological processes. Specifically, the exhaust gas first enters the tower and comes into contact with the absorbent or adsorbent through the packing layer and spray layer, undergoing adsorption, absorption, chemical reaction, or biodegradation processes, thereby removing or transforming harmful substances in the exhaust gas into harmless substances. Finally, the treated clean air is discharged from the top of the tower, achieving the purpose of purifying the exhaust gas.

[0003] After long-term use, dust and other insoluble particulate matter in the exhaust gas will gradually accumulate inside the packing material of the exhaust gas treatment tower. If these accumulations are not cleaned for a long time, they will easily cause blockages.
