Abstract

The invention provides a multi-stage dust remover by adopting bionic vanes for improving dust removing efficiency. The multi-stage dust remover comprises an inertial dust removing device, a bionic vane device and a spraying wet-type dust removing device, wherein the inertial dust removing device is in through connection with the bionic vane device; the bionic vane device is in through connection with the spraying wet-type dust removing device. By skillfully integrating an ordinary inertial dust remover with bionic vanes, a dry-type dust removing device and the spraying wet-type dust removing device, the formed multi-stage dust remover can be used for processing life and industrial dust with the over-standard concentration, and has the advantages of being light in weight, simple in structure, low in price, easy to maintain, convenient to operate and manage and the like.

Description

technical field [0001] The invention relates to flue gas dust removal technology in the field of environmental protection, in particular to a multi-stage dust collector which uses bionic blades to improve dust removal efficiency. Background technique [0002] In the purification of dusty gas in industrial fields such as mining and coal preparation, dust pollutants with high concentration, high hardness and wide particle size range are often encountered. More and more stringent, so the flue gas purification equipment also put forward higher requirements. As the main equipment for controlling air pollution caused by solid particles, the dust collector is facing a huge opportunity for development. Inertial dust collectors are generally used for the treatment of metal or mineral dust with high density and coarse particles. It is not suitable for collecting dust with small density and fine particles or fibrous dust, so it is a commonly used pre-dust removal equipment; the theory...
