Description

Technical Field

[0001] The utility model relates to the technical field related to desulfurization towers, in particular to a multi-stage spray type desulfurization tower. Background Art

[0002] A desulfurization tower is a tower-type equipment used to reduce sulfur dioxide emissions in industrial waste gas. The main function of a desulfurization tower is to convert SO2 in sulfur-containing flue gas into a harmless or easy-to-handle form through chemical processes or physical effects, thereby reducing environmental pollution. With the development of technology, desulfurization towers are gradually made of materials such as fiberglass, making them lighter and more corrosion-resistant. In addition, desulfurization towers can achieve the effects of dust removal and desulfurization at the same time by adding different dust removal agents. Therefore, a multi-stage spray desulfurization tower is particularly needed.

Secondly, when the flue gas is discharged into the desulfurization tower, the flue gas may float out of the smoke inlet of the desulfurization tower, causing pollution to the environment.
