1.Sort by cleaning method
The cleaning method is an important factor in determining the performance of the bag filter. It is proportional to the dust removal efficiency, pressure loss, filtration wind speed and filter bag life. The classification standard of the national bag dust collector is classified according to the cleaning method. . According to the cleaning method, the bag filter can be divided into five categories: mechanical vibration, nozzle back-blowing, chamber back-blowing, vibration back-blowing, and pulse blowing. In addition, bag filters can be classified according to their appearance, scope of application, and use.
2.Classification according to the pressure in the bag filter
According to the pressure classification of the bag filter, it can be divided into two types: negative pressure type dust collector and positive pressure type dust collector. Positive pressure type dust collector, the fan is set before the dust collector, and the dust collector works under positive pressure. Since the dust-containing gas passes through the fan first, the wear of the fan is serious, so it is not suitable for dust with high concentration, coarse particles, high hardness and strong corrosiveness. Negative pressure type dust collector, after the fan is placed in the dust collector, the dust collector works under the negative pressure state. Since the dust-containing gas is purified and then enters the fan, the wear of the fan is small, and this method is adopted more.
