Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization reactors, in particular to an SDS desulfurization reactor. Background Art

[0002] At present, there are three general desulfurization methods: desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. Many flue gas desulfurization processes have been widely used in industry, and they also have important practical significance for the treatment of tail gas from various boilers and incinerators.

[0003] A Chinese patent with publication number CN213725775U was searched and disclosed, which discloses an SDS desulfurization reactor. By setting a partition plate, the bubbles inside the reaction tower are dispersed more evenly, a large number of bubbles react fully with the solution, and the bubbles are divided again by the air permeable plate into small bubbles, thereby accelerating the reaction rate.

[0004] Based on the above search and combined with the prior art, it was found that the above patent has certain defects. The direct input of gas through the outlet hole on the exhaust pipe and the reaction with the solution are not sufficient. The reaction of gas and solution produces impurities, which mostly stay at the outlet position and are prone to precipitation and clogging. Moreover, the gas after passing through the air permeable net cannot be evenly distributed and cannot completely contact and react with the sprayed solution, which reduces the utilization efficiency of the desulfurization reactor.
