The quality of dust emitted by industrial dust collectors in the exhaust gas varies widely, and the emission requirements are different. therefore. To choose a cost-effective dust-removal device, in addition to fully grasping the performance of various dust-proof devices, you must also fully understand the situation of the source of the pollution, such as gas flow, temperature, pressure, moisture content, corrosiveness, viscosity, explosiveness, and dust Concentration, particle size and distribution, density, corrosivity, hygroscopicity, electrical conductivity, adhesion, etc., in addition to the requirements of emissions, the purpose of dust removal and the actual situation on the site.
1. Reasonably select the dust collector according to the gas discharge amount. For example, if the gas amount is large, it is more advantageous to use a cyclone dust collector.
2. Select the dust collector according to the physical properties of the dust. If sticky dust is used, dry dust removal should be adopted;
3. Bag type dust collectors are not suitable for high temperature and high humidity gases; wet dust collectors should be used for smoke containing gaseous pollutants such as SO2 and NO2;
4. For gas with high dust concentration in industrial dust collectors, it is not suitable to directly use bag-type or electric dust collectors, and low-resistance primary purification devices should be provided in advance;
Fifth, consider the treatment capacity after capture. If the process itself is equipped with a mud treatment system or hydraulic conveying mode, wet dust removal should be used;
