Description

High-efficient dust collecting equipment of sandblast waste gas Technical Field The utility model relates to the field of environmental engineering and industrial air purification, in particular to high-efficiency dust removal equipment for sand blasting waste gas. Background The high-efficiency dust removing equipment for the sand blasting waste gas is environment-friendly equipment for treating waste gas and dust generated in the sand blasting process. The sand blasting is a surface treatment process, and the purposes of cleaning, rust removal, surface roughening and the like are achieved by spraying sand grains or other abrasive materials on the surface of a workpiece at a high speed. However, this process generates a large amount of dust and fine particles, which not only pollute the environment, but may also cause harm to the health of operators. At present, most dust removing equipment on the market generally faces a problem after long-time operation, namely, along with the increase of service time, a large amount of dust is gradually accumulated on the surface of a filter bag, and the situation causes the continuous increase of resistance when air flows pass through the filter bag, so that the overall working efficiency of the dust removing equipment is obviously reduced, and the phenomena of slow filtering speed, increased energy consumption, weakened purifying effect and the like are particularly shown, long-term dust accumulation not only increases the burden of the equipment, but also can cause premature abrasion of filter bag materials to influence the service life of the filter bag, and the maintenance cost and the downtime are greatly improved due to frequent manual cleaning or replacement of the filter bag. Aiming at the problems, a sand blasting waste gas high-efficiency dust removing device needs to be designed.
