1. Water curtain dust removal, as the name implies;
2. The spray tower sprays water through the top of the tower, and a multi-layer filter screen is made in the tower, so that the water forms a water film on the filter screen and the dusty air passes through the water film, and the dust removal efficiency is similar to that of the water curtain, generally 70%;
3. Venturi dust collector is based on Venturi principle, which makes water and air merge with dusty air through instantaneous contraction and expansion. The dust removal efficiency is high, generally 3-5 microns can be treated up to 95%. The only drawback is that it requires too much pressure and consumes electricity.
4. Water-washing dust collector is also called centrifugal wet dust collector, and its working principle is as follows: primary dust removal: dusty air enters the water through negative pressure ventilation; Deep dust removal refers to making a circulating vortex plate in the rising space of water level when negative pressure is drawn away from the water level, so that dusty air and water can be fully mixed to achieve the purpose of high-efficiency dust removal. The dust removal efficiency of this kind of dust removal is basically similar to that of Venturi, reaching 98% at 3-5μm, and its pressure is lower than that of Venturi.
