Description

Technical Field

[0001] This invention relates to the field of demisting equipment technology, specifically to a gas phase demisting device at the top of a nicotinic acid tower. Background Technology

[0002] The flue gas exiting the chimneys of power plants contains large amounts of harmful substances such as sulfur dioxide. These substances are emitted directly into the atmosphere without treatment, polluting the environment. Currently, wet desulfurization technology is commonly used to remove sulfur dioxide and other harmful substances from the flue gas. However, during operation, wet desulfurization absorption towers easily generate large amounts of water mist. The flue gas is discharged with a large amount of water mist, which often contains sulfuric acid and sulfates, easily causing corrosion of fans, heat exchangers, and flue ducts. Therefore, it is necessary to perform demisting treatment on the gas purified by wet desulfurization.

[0003] In the prior art, application number CN201921686600.2, entitled "A Flat Plate Desulfurization Demister," describes a technical solution that includes an upper fixing plate for demister blades, a lower fixing plate for demister blades, demister blades, connecting bolts, and positioning blocks. Demister blades are evenly spaced between the upper and lower fixing plates. The demister blades are fixedly connected to the upper and lower fixing plates via connecting bolts. Demister blade locking blocks, which mate with the demister blades, are evenly spaced on the surface of the upper fixing plate. These locking blocks are integral with the upper fixing plate, and bolt mounting holes for mates with the connecting bolts are provided on the locking blocks. This results in a more secure connection between the demister blades and the upper and lower fixing plates.

[0004] The aforementioned flat-plate desulfurization demister is prone to corrosion and damage under long-term use. The demister blades and fixing plate in the above technical solution are an integrated structure. When a demister blade is damaged, the entire unit needs to be replaced, which is inconvenient for maintenance and has high maintenance costs. Summary of the Invention
