During the subsequent disassembly, it is easy to cause problems such as inconvenience in disassembly and replacement of the filter medium. Therefore, an industrial waste gas dust removal and deodorization device is needed to assist in solving this problem. Utility Model Content

After being ejected from the air outlet 62, it reacts with the oxidant solution inside the reaction tube 1. The overall odor of the exhaust gas is removed by the reaction between the exhaust gas and the oxidant solution. The removed gas is discharged through the exhaust pipe 2 for subsequent processing.
