Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a horizontal washing tower. Background Art

[0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume, complex and diverse composition, and its pollution, resource and social nature, it needs to be harmless, resource-based, reduced and socialized. If it is not properly handled, it will pollute the environment, affect environmental hygiene, waste resources, destroy production and life safety, and destroy social harmony. A large amount of waste gas will be generated during the collection and treatment of garbage. These waste gases are accompanied by certain odors, which will seriously affect the surrounding environment and the health of workers, so a scrubber is needed to purify the gas. The scrubber is improved on the basis of the floating packing layer gas purifier. It is widely used in pre-treatment of industrial waste gas purification, dust removal, etc., and the purification effect is very good. Existing scrubbers are mostly set in a vertical direction, which is inconvenient for the maintenance and operation of the scrubber, and mainly rely on water washing, so the demand for water is large, which is easy to cause water waste.
