Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection devices, in particular to a spray dust removal and desulfurization tower. Background Art

[0002] The spray dust removal and desulfurization tower is an important industrial equipment, mainly used to treat sulfides and dust in industrial waste gas. It includes a tower body. Since the flue gas dust removal and desulfurization are carried out inside the tower body, when the dust content in the flue gas is high, the dust removal and desulfurization efficiency inside the tower body will be greatly affected.

[0003] The application document with application number CN202322297095.5 in the patent library discloses a high-efficiency flue gas desulfurization and dust collector, which arranges a filter cartridge in the dust inlet, effectively reducing the dust content inside the tower body and ensuring the desulfurization and dust removal efficiency. However, since the filter cartridge is at the top of the desulfurization and dust removal work, a large amount of dust will gather at the filter cartridge position, causing the dust inlet to be blocked, which requires regular replacement of the filter cartridge. When replacing the filter cartridge, all connected pipes need to be disassembled to complete the replacement, and during the replacement process, the dust inlet will be unusable, which makes the replacement of the filter cartridge more troublesome and cannot be carried out during the smoke intake work.
