Air driven spray is a new type of spray dust removal device, which is composed of fan, centrifugal pump, reservoir, etc. During operation, the water is purified by sedimentation and transported to the fan port, where atomized particles are sprayed out through the nozzles arranged in an orderly manner on the fan port. This device not only has a simple structure, a large dust removal coverage, and good dust removal effect, but also has low requirements for water quality. It can directly use rainwater and other recycled water, thereby significantly reducing investment costs.
