① Selection of filter bag material for bag dust collector. Because the environment, the nature, temperature, and technical requirements of different dust collection point are different, the corresponding filter bag material of the dust collector is also different. If you want the filter bag to have good dust removal performance, good air permeability, low resistance, high filtration efficiency, high strength, can withstand high-strength dust removal, and long service life, you must choose the appropriate one according to different working conditions. material.
② The filtering air velocity is an important parameter that determines the efficiency of the dust collector, and it is also an important parameter to measure the advanced nature of the bag dust collector. The filtering air velocity is closely related to the dust concentration of the dust-containing gas, the particle size of the dust particles and the method of cleaning. Generally, when the dust concentration is high, the filtering air velocity should be lower, and vice versa. The smaller the dust particles, the smaller the filtering air velocity. Excessive filtering air velocity will increase the load of the filter bag and increase the filter resistance, resulting in a short service life and low efficiency of the filter bag.
③ Air leakage will directly affect the dust collection effect. Bag dust collectors generally also operate under negative pressure. If air leakage is likely to cause a short circuit in a small circuit, the dust collection system will not handle enough air volume, which will cause positive pressure to raise dust. Air leakage will also cause a decrease in system temperature, resulting in dew condensation and bagging, increasing the resistance of dust collection and reducing the dust collection effect.
④Insulation is also important for filter bag dust collection. Insulation is to keep the temperature of the gas, so as to avoid condensation and sticky bags.
