TECHNICAL FIELD

[0001] The utility model relates to the field of desulfurization and denitrification, especially to a desulfurization and denitrification environmental protection equipment for industrial power plant. BACKGROUND

[0002] Desulfurization and denitrification is the core process of industrial flue gas purification, and the core goal is to remove sulfur oxides and nitrogen oxides in flue gas to meet environmental emission standards, while reducing acid rain, haze and other air pollution. It is an essential environmental protection link for coal-fired power plants, steel, cement, chemical and other industries.

[0003] The patent application with publication number CN219482081U proposed in the prior art filters the dust in the flue gas through the filter bag during the entire use process. The filter bag can be repeatedly cleaned by the cleaning assembly, so it does not need to be replaced regularly, which greatly reduces the workload of the staff and makes it more convenient to use. During use, the electromagnetic valves connected to the two cleaning pipes can be alternately opened. In this way, the flue gas inside the dust treatment box can always have a path to the exhaust pipe, so that the entire equipment can remain in operation, thereby eliminating the need for shutdown for cleaning and effectively ensuring production efficiency.

[0004] However, when the smoke pipe enters the inside of the dust treatment box, the filter bag will be cleaned and accumulated inside the dust treatment box, which will cause the dust to be reabsorbed on the surface of the filter bag, resulting in clogging of the filter bag and reducing the filtering effect.

[0005] Therefore, it is necessary to provide a desulfurization and denitrification environmental protection equipment for industrial power plant to solve the above technical problems. SUMMARY

[0015] Preferably, the interior of the housing has two movable slots, and each of the two movable slots is slidably connected to a movable block.

[0016] Preferably, one side of each of the two movable blocks is fixedly connected to both ends of the cleaning brush.

[0017] Compared with related technologies, the desulfurization and denitrification environmental protection equipment for industrial power plants provided by this utility model has the following beneficial effects:

[0018] This utility model provides a desulfurization and denitrification environmental protection equipment for industrial power plants. A servo motor, in conjunction with a rotating rod, a torsion spring, and a support frame, causes multiple rotating plates to rotate to one side and then reset, thereby beating the filter bags and cleaning them.
