Description

Flue gas treatment device Technical Field The utility model relates to the technical field of flue gas treatment, in particular to a flue gas treatment device. Background In some industrial processes, a large amount of flue gas is produced, which needs to be treated and purified before being discharged to the atmosphere. At present, the flue gas is generally treated by using a gas-liquid reaction technology, specifically, the flue gas to be treated is conveyed into a reaction container, and a slurry conveying pipe provided with a slurry spray header is used for spraying reaction slurry for reacting with the flue gas into the reaction container, so that harmful substances in the flue gas are removed by using the reaction of the reaction slurry and the flue gas. However, the flue gas after reacting with the reaction slurry may also carry some small solid particles and small liquid droplets, and some solid particles and liquid droplets may also cause a certain pollution to the atmosphere, or if the flue gas is subjected to the next processing procedure, the flue gas carrying too many solid particles and liquid droplets may also cause damage to subsequent equipment (e.g. a pump). Disclosure of utility model It is an object of the present utility model to provide a flue gas treatment device that helps to reduce particles and droplets in the flue gas exiting the flue gas treatment device. In particular, the present utility model provides a flue gas treatment device comprising: A housing formed with a reaction space, and an air inlet and an air outlet communicating with the reaction space; A slurry delivery pipe disposed in the reaction space, the slurry delivery pipe being provided with a slurry shower head for spraying the reaction slurry into the reaction space, and The defogging structure sets up the thick liquid conveyer pipe with between the gas outlet, the defogging structure includes: The tip cover comprises two air passing plates, wherein the two air passing plates are connected with each other at the side edge close to the air outlet in the up-down direction and are separated from the side edge far away from the air outlet, the air passing plates are provided with air passing holes for allowing flue gas to flow from the bottom side to the top side of the tip cover, and The cleaning fluid conveying pipe is arranged between the two air passing plates and is provided with a plurality of spray heads for spraying cleaning fluid to the air passing plates.
