Description

technical field

[0001] The invention relates to a spray gun used in desulfurization and denitrification operations. Background technique

[0002] The desulfurization and denitrification tower is mainly composed of a flue gas conveying system, an absorption tower, a spray system, a slurry circulation system, and a slurry recovery system.

[0003] The industrial waste gas transports a large amount of sulfur dioxide, carbon dioxide, etc. waste gas to the absorption tower through the flue gas conveying system. A large amount of desulfurization agent in the absorption tower is transported to the tower body by the spray system. The desulfurizer and industrial waste gas with a certain pressure and detachment ability Full contact produces a chemical reaction. In order to make the sulfur dioxide in the waste gas form a precipitate and flow to the bottom of the tower, it is discharged from the slurry circulation system to the outside of the tower for recycling. After desulfurization a...
