Description

Technical Field

[0001] The utility model relates to the technical field of bag dust removal, in particular to a novel boiler bag dust removal device. Background Art

[0002] In industrial production, boilers, as crucial thermal energy conversion equipment, are widely used in power generation, heating, chemical engineering, and other fields. However, the boiler combustion process produces large amounts of exhaust gas containing smoke, particulate matter, and harmful gases. If these exhaust gases are directly discharged into the atmosphere, they will seriously pollute the environment, affecting human health and the ecological balance. Therefore, effectively treating boiler exhaust gas and reducing pollutant emissions have become urgent issues in the environmental protection field.

[0003] Traditional boiler exhaust gas treatment equipment often utilizes wet dust removal or electrostatic dust removal technologies, but these methods have numerous shortcomings in practical application. While wet dust removal can effectively remove some particulate matter, it can easily cause secondary pollution, and the treated wastewater is difficult to handle. While electrostatic dust removal offers high dust removal efficiency, it has limited effectiveness in capturing fine particles, and the equipment is complex and requires high maintenance costs. Bag filter technology, as an efficient and stable dust removal method, has gained widespread application in boiler exhaust gas treatment due to its simple structure, high dust removal efficiency, and strong adaptability.

[0004] However, existing boiler bag filters still have some shortcomings. First, because boiler exhaust contains a large amount of hot, humid, and highly viscous soot and particulate matter, these particles easily form lumps on the bag surface, causing blockage and affecting dust removal efficiency. Second, over time, large amounts of dust accumulate on the bag surface. If not cleaned promptly, this not only reduces dust removal efficiency but can also damage the bags, shortening the life of the equipment. Utility Model Content
