The Reason For The Efficiency Of The Filter Bag

The reason for the efficiency of the Filter Bag
       The reasons for the efficiency of the Filter Bag generally have the following:
       First, Filter Bag material
       Filter Bag material selection and application, is the core technology of bag-type dust collection equipment, the performance of the Filter Bag plays a decisive role. Due to the dust dust collection environment, the nature of dust, temperature, technical requirements are not the same, for different conditions, choose a different filter material, and only to the appropriate technical protection measures, the requirements of the Filter Bag materials include the following Performance: Filter Bag material for different temperatures, good stripping, easy to clean, good ventilation, low resistance, high filtration efficiency, high strength, can withstand high-intensity cleaning, long life, cheap.
        Second, the air leakage
       Air leakage directly affect the Filter Bag dust collection effect and life, requiring leakage rate <3%. Bag filter are generally negative pressure operation, such as leakage easily formed a small loop short circuit. Dust collection system handling air volume is not enough to form a positive pressure dust. Leakage will also reduce the system temperature, easy to tide paste bag, increase the dust collection resistance, reduce the filtering effect.
       Third, filter the wind speed
       Filtration wind speed is a very important parameter that affects the performance of the dust collector, but also an important parameter to measure the advanced nature of the Filter Bag. The filtration wind speed is closely related to the dust concentration, the particle size of the dust particles, the application, the viscosity, the gas temperature, the moisture content and the cleaning method. When the dust particle size is thin, temperature, humidity, high concentration, large viscosity, the filter wind speed should be taken lower, and vice versa optional high value. Filtration wind speed is too large, will increase the Filter Bag load, increase the filtration resistance, resulting in Filter Bag life is short, low efficiency.
