Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, in particular to a waste gas treatment device for herbicide production. Background Art

[0002] Herbicides are agents that can cause weeds to die completely or selectively. Herbicide production generates waste gas, and various waste gas collection and treatment devices have been proposed in the prior art. For example, Chinese Utility Model Patent Publication No. CN221207433U proposes a glufosinate-ammonium herbicide tail gas collection device. This tail gas collection device is designed with a water treatment component, a sterilization component, and an adsorption treatment component. The water treatment component serves as the first step in treating the tail gas. Treatment water and a solvent are added to the interior of a bottom box. The tail gas enters the water and first dissolves harmful substances in the water before being discharged. After discharge, the tail gas passes through the sterilization component for the second step. A high-temperature sterilization lamp sterilizes and dries the gas ejected from the water. The gas is then further sterilized by an ultraviolet light panel. Finally, the gas enters the top box. The inner box of the top box can be filled with alkaline adsorption and filtration materials to finally treat harmful substances in the waste gas. This process can fully treat the waste gas and effectively save consumables costs.

[0003] However, when the exhaust gas collection and treatment device uses ultraviolet lamps and high-temperature sterilization components to treat exhaust gas, the exhaust gas has a short contact time with the ultraviolet lamps and high-temperature sterilization components, resulting in reduced exhaust gas treatment effect. Utility Model Content
