① Selection of filter bag material for bag dust collector. Because the environment of the dust collection point, the nature, temperature, and technical requirements of the dust are different, the corresponding filter bag material of the dust collector is also different. To make the filter bag material temperature suitable, good stripping, easy to clean, good breathability, low resistance, high filtration efficiency, high strength, can withstand high-strength cleaning, long service life, it is necessary to choose materials according to local conditions and technical requirements .
② The filtering air speed 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 speed 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 wind speed should be lower, and vice versa. The smaller the dust particles, the smaller the filtering air speed. Excessive filtering air speed 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 directly affects the dust collection effect. Bag dust collectors are generally operated under negative pressure, such as air leakage is easy to form a short circuit short circuit, the dust collection system does not handle the air volume enough, forming positive pressure dust. The air leakage also forms a system to reduce the temperature of the system, easy to condense the paste bag, increase the dust collection resistance, and reduce the dust collection effect.
④Insulation is also a must for bag collection. Insulation is to maintain the temperature of the gas and avoid condensation bags.
