Filter principle: work into the dust hopper dust stream from the lower box, bag filter device, since sudden expansion of the air flow cross-sectional area, flow rate lowered dedusting equipment workshop, part of a stream of large particles, dust and high density agglomeration of dust particles in the centrifugal force and gravity along the tube wall spin off the hopper; tiny dust particles fine grain size, density of the suspension in the gas flow distribution by means uniformly dispersed into the filter chamber gap in the bag by bag inertial impaction surface, sieve and other effects deposited in the bag surface, dust collector parts, polishing dust removal equipment, purge gas discharged from the main fan. Filtration velocity selection filtration velocity level, Jiaozuo dust removal equipment, depending on the nature of dust, and into the dust of gas dust concentrations size, and can be determined with reference to the following: the entrance of dust concentration ≤30g / m3, filtration velocity = 0.8 ~ 1.2m / min; the entrance of dust concentration ≥30g / m3, filtration velocity = 0.5 ~ 0.8m / min. Polishing dust removal equipment, environmental protection three wins (online consultation), dust removal equipment supplied by Henan Jiaozuo three wins Environmental Technology Limited. Henan three wins Environmental Technology Limited (www.hnsshbkj.com) (www.hnsshbkj.com) is a leader in Zhengzhou, dust removal equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the three wins environmental leadership with the staff warmly welcome all inquiries negotiations to create environmentally friendly three wins better future.
