Background

The wet dust collector is commonly called as a demister, 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 and other actions of water and dust to capture the particles or enlarge or retain the particles in a fixed container to achieve the effect of separating the water from the dust. The wet dust collector is produced by combining two forms of water bath and spraying, the dust-containing gas is pressed into a water tank filled with water with a certain height by utilizing the suction force of a high-pressure centrifugal fan, part of dust is adsorbed in the water by the water bath, the gas flows from bottom to top after being uniformly distributed and shunted, a high-pressure spray head in the wet dust collector sprays water mist from top to bottom to collect the rest dust particles, and the filtering efficiency of the wet dust collector can reach more than 85 percent. In industrial dust removal, wet dust collectors are widely used because of their advantages of low investment, no secondary dust emission, being resistant to adhesion, fire and explosion, and can effectively remove liquid or solid particles with a diameter of 0.1-20 μm from an air stream, and also remove a part of gaseous pollutants.
