The process of dust and gas is actually aprocess of separation of dust and toxic gases from contaminated air stream; trying to "keep them" before being discharged into the environment and can bedone invarious ways. In fact it is often combined treatment with toxic dust and, wet with the device: empty gas washing tower, tower padding, foam, centrifugal filter deviceinertia. andVentury equipment. Dust wet method was researched and studied on a radial pattern similar experiments in the field and applications based on the effect of swirling air flow with the shock pulse generated finemist particles, the size reasonable density to increase efficiency filter dust and toxic gases. The device worked and installed at several production facilities that is cheaper than others, but (or very high filtration efficiency, simple operation and special equipment are working with very stable performance regulations; overcome some disadvantages that other classical devices of tenasblockages in the device result in the deviceto work with unstable performance. The device worked and installed at several manufacturing facilities.
