Description

Technical Field

[0001] The utility model relates to the technical field of boiler waste gas treatment, in particular to a boiler waste gas treatment device with multiple filtering components. Background Art

[0002] Boiler exhaust gas contains a large amount of harmful substances, such as sulfur oxides, nitrogen oxides, particulate matter, etc. These substances directly discharged into the atmosphere will have a serious impact on the environment and even threaten human health.

[0003] According to the patent name: A boiler exhaust gas treatment device (patent announcement number: CN217909666U, patent announcement date: 2022-11-29), through the setting of the moving mechanism and the rotating plate, when the end of the rotating plate connected to the active plate rotates to the far left, the movement of the driven plate drives the gear block to move counterclockwise along the trajectory of the gear on the inner wall of the through groove to the next gear gap on the inner wall of the through groove. When the end of the rotating plate connected to the active plate rotates to the far right, the movement of the driven plate drives one end of the gear block to move in the direction of the pointer against the gear gap on the inner wall of the through groove. The gear block causes the inner gear ring to move along the inner wall of the spray tower. The movement of the rotating plate drives the nozzle to evenly sprinkle water on the packing layer, thereby expanding the actual spraying range. When a nozzle is blocked, the nozzles arranged on other sides of the nozzle tube can still evenly sprinkle water on the top of the packing layer without affecting the treatment of the exhaust gas by the packing layer.

[0004] Based on the above-mentioned prior art, the existing boiler exhaust gas treatment device still has the following problems: the existing boiler exhaust gas treatment device mainly relies on a single filtering device to perform the exhaust gas filtering task. However, this single treatment method often cannot achieve comprehensive and efficient filtration of complex harmful substances in the exhaust gas. Since boiler exhaust gas usually contains a variety of pollutants, such as particulate matter, sulfur oxides, nitrogen oxides, etc., each pollutant requires a specific treatment method to be effectively removed. Therefore, a single filtering device is often difficult to cope with this diversified combination of pollutants, resulting in poor filtering effect and difficulty in achieving ideal emission standards. For this reason, the utility model provides a boiler exhaust gas treatment device with multiple filtering components. Utility Model Content
