How to choose a good quality bag filter:
1. When selecting the model of the bag filter, the first thing is to accurately grasp the dispersion degree of the dust. For example, if the particle size is more than 10υm, a cyclone dust collector can be selected. If the particle size is more than several micrometers, you should choose electrostatic precipitator and bag precipitator. For specific selection, you can make a preliminary selection by referring to the type and performance table of common precipitators according to the degree of dispersion and other requirements; then follow other conditions and introductions. The type and performance of the dust collector is determined. Dust density also has a great impact on the dust removal performance of the dust collector. The most obvious manifestations of this effect are gravity, inertial and centrifugal precipitators. A common feature of all baghouse dust collectors is that the smaller the bulk density, the more difficult the separation and capture of dust particles, and the more serious the second fly of dust, so special measures should be taken in operation and equipment structure.
2. In principle, dry dust removal equipment must be carried out at a temperature above the dew point of the dust-containing gas. In wet dust collectors, due to water evaporation and condensation after being discharged to the atmosphere, it should be treated at as low a temperature as possible. In the filter cartridge dust collector, the temperature for directly or indirectly processing the dust-containing gas should be lower than the heat resistance temperature of the filter cloth. The operating temperature of glass fiber filter cloth is generally below 260 ° C. Other filter cloths are between 80 and 200 ° C.
How to choose a good quality bag filter: 3. The amount of processing gas is the decisive factor in determining the size and type of the bag filter. For the air volume, you must choose a bag filter that can handle the air volume. If you use multiple It is often uneconomical to use a dust collector in parallel; for a smaller gas volume, it is more economical to compare which type of dust collector is the most economical and the easiest to meet the environmental requirements of dust source control and dust emission.
4. In the cyclone dust collector, the dust adheres to the wall due to centrifugal force, and there is a danger of clogging; the dust adhered to the bag dust collector may easily block the filter bag openings, and the electrostatic precipitator may cause the electrode and the collector The dust is extremely dusty.
5. The larger the dust concentration in the inlet, the higher the dust removal efficiency. However, this will increase the dust concentration in the outlet. Therefore, you cannot generalize that the dust treatment effect is good only from the high dust removal efficiency. Venturi tube dust collector, jet washing For wet-type dust collectors such as air cleaners, the initial dust concentration is preferably below 10g / m. For bag dust collectors, the lower the dust concentration, the better the removal performance, at higher initial concentrations. With continuous ash cleaning, pressure loss and discharge concentration can also meet environmental protection requirements.
