Selection factors of the dust collector

The selection of dust collector must be based on the investigation and study, and according to the difference in the treatment of dust, mainly from the dust removal efficiency, processing capacity, power consumption and economic aspects to consider comprehensively. It should be determined through technical and economic comparison, the following are some points to note when selecting the dust collector: (1) The chemical composition, corrosivity, explosiveness, temperature, humidity, dew point, gas volume and dust concentration of dust-laden gas; (2) Dust chemical composition, density, particle size distribution, hydrophilicity, rubbing degree, specific resistance, adhesion, fiber and flammability, explosiveness, etc.; (3) Processing gas volume: Determine the amount of flue gas as the basis of the purification system design; (4) Dust collector pressure loss, dust removal efficiency; (5) Dust recovery value and recycling form; (6) Dust collector equipment costs, operating costs, service life, site layout and external water supply conditions; (7) The simplicity of maintenance management. When selecting and designing the dust collector, special attention should be paid to the following matching issues: The dust concentration of the purified gas at the outlet of the dust collector must be matched with the emission concentration requirements of the environmental protection regulations; The performance of the dust collector must match the gas properties and the nature of the dust being treated; The dust collection method of the dust remover should be matched with the method of removing the dust; The selected dust collector should be matched with environmental factors and must have certain environmental, economic and social benefits.
