[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially from chemical plants, steel mills, pharmaceutical plants, coking plants and refineries. The waste gas emitted has a strong odor, seriously polluting the environment and affecting human health. For waste gas containing sulfur and nitrogen, desulfurization and denitrification treatment equipment is needed to complete the desulfurization and denitrification treatment of waste gas. In actual use, it has the advantages of simple operation, stable treatment and good use effect.

The waste gas treatment device of the utility model can be used for the denitrification and desulfurization treatment process in the activated carbon adsorption method. The waste gas treatment device adopts a vertical activated carbon storage barrel storage structure to store activated carbon particles, which can effectively increase the contact area between the activated carbon and the gas, thereby improving the adsorption efficiency of the activated carbon. At the same time, the storage barrel adopts a lifting sealing structure, and the storage barrel can be quickly opened and closed by a hydraulic cylinder structure, thereby emptying the activated carbon particles in the storage barrel, so as to realize the rapid replacement of the activated carbon product in the storage barrel. Compared with the traditional horizontally placed activated carbon particle layer, it not only improves the waste gas treatment efficiency, but also can quickly realize the rapid collection and replacement of activated carbon particles.

This method of replacing activated carbon particles will affect the treatment efficiency of the exhaust gas desulfurization and denitrification of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
