Lens electric-bag complex dust collector

Abstract

The invention relates to a lens-type electric bag composite dust collector which utilizes the characteristics that a lens-type electric dust collector has higher dust collecting efficiency of a dust collecting space than a wire-plate electric dust collector and better adaptability to high specific resistance dust and superfine dust, an electric field of the pre-stage lens-type electric dust collector collects the most of the dust containing the high specific resistance dust and the superfine dust in advance and reduces the high specific resistance dust and the superfine dust in the dust which enters a post-stage bag dust collector to the utmost extent, thus ensuring the gathered dust to have better looseness and permeability, reducing the running resistance and the working load of the post-stage bag dust collector, further reducing the comprehensive cost of the dust collector and prolonging the service life.

Description

technical field [0001] The invention belongs to the technical field of air dust removal, and mainly relates to a novel composite dust collector which is a combination of a lens type electric dust collector and a bag type dust collector. Background technique [0002] Because a large amount of flue gas and fly ash will inevitably be produced in industrial production, and the flue gas also contains a large amount of fine particle dust, the direct discharge of these dusts will cause serious pollution to the environment, cause varying degrees of damage to the ecological environment, and bring harm to people. Therefore, environmental protection organizations around the world continue to strengthen the protection of the environment, especially the control of air pollution, and enforce purification measures for industrial waste gas emissions; It played a very important role in it, and the contribution is indispensable; however, with the continuous improvement of people's living envi...

Problems solved by technology

However, due to the disadvantage of poor adaptability to high specific resistance dust and fine dust in the line plate dust collector, and these dusts are the main factors leading to the increase of the running resistance of the filter bag of the bag filter; because only the dust layer on the surface of the filter bag The larger the dust particles and better looseness, the better the permeability and the smaller the running resistance; also, because the high specific resistance dust can hardly be ionized and charged by the electric field of the wire plate electrostatic precipitator, and these dust It is very easy to form agglomerates in the dust layer of the filter bag, which will seriously affect the permeability of the dust layer and increase the running resistance

Therefore, the electric bag combined dust collector in this form still has a large running resistance, so it still has a great impact on the life of the filter bag.
