Description

High-efficient wet dust collector

Technical Field

Background

Industrial dust is one of the main sources of inhalable particles in the atmosphere, which often has harmful effects on the environment and human health, and before being discharged into the atmosphere, purification measures should be taken to process the industrial dust so as to ensure that the industrial dust meets the requirements of exhaust emission standards, and industrial waste gas mostly contains smoke dust, organic matters, peculiar smell, acid-base waste gas, chemical derivatives and the like. Currently, industrial dust is usually removed by a dust remover. Dust collectors are mainly dry type dust collectors and wet type dust collectors. The wet dust collector is commonly called as 'water dust collector', and is a device which makes dust-containing gas and liquid (generally water) closely contact, utilizes the inertia collision of water drops and particles or utilizes the full mixing action of water and dust and other actions to trap the particles or make the particles increase or remain in a fixed container to achieve the effect of separating water from dust.

Although the wet dust collector is low in power of the fan and low in operation cost in practical application, the dust collection effect is poor. Therefore, a wet dust removal device with high dust removal efficiency, which can atomize liquid to increase the specific surface area of the liquid and enhance the dust capture capacity is urgently needed in the field of waste gas purification.
