Description

Technical Field

[0001] The invention relates to the technical field of waste gas purification, and in particular to a horizontal acid-base waste gas washing tower. Background Art

[0002] Most of the scrubbers available on the market are vertical scrubbers, with the water tank separated from the tower body, occupying a large area; it is difficult to replace the filler and clean the tower body. The acid and alkali waste gas treatment equipment of the electronics factory is generally placed in the indoor exhaust room. Due to the influence of the air duct, bridge, dosing and drainage pipelines in the space, the height of the scrubber is limited. Therefore, the vertical scrubber is generally not suitable for the acid and alkali waste gas treatment of the electronics factory.

[0003] However, when the existing horizontal scrubber is spraying acid and alkali waste gas, particulate impurities will flow back to the water tank with the liquid medicine for storage, and the water tank needs to be cleaned regularly by humans, otherwise the particulate impurities will pollute the liquid medicine. The current cleaning process is relatively laborious and the cleaning efficiency is low.

[0004] For this purpose, a horizontal acid-base waste gas washing tower is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problems mentioned in the above background technology, and the present invention provides a horizontal acid-base waste gas washing tower.
