The selection of the pulse bag filter should be matched with the fan. Usually, the high-pressure pulse bag filter is selected, and the bag is required to be waterproof and oil-proof. The pulse bag filter can select the low pressure pulse bag filter in the case of the low air pressure fan, and the high pressure pulse bag filter is preferred when the high pressure fan is dusted, because the back pressure of the low pressure pulse bag filter is relatively low. When the dust of the high-pressure fan is treated, the pressure difference between the inside and the outside of the bag is relatively small, and the dust on the bag is not easily blown back, which affects the dust removal efficiency. When the moisture content of the raw material is large, you need to choose a tarpaulin bag. The processing air volume of the pulse bag filter is selected according to the fan volume of 1.2 to 1.5 times. The selection of the cyclone unloader is very important, and the domestic cyclone unloader is mostly designed with reference to the centrifugal dust collector. The centrifugal dust collector functions as dust removal, while the cyclone discharger mainly plays the role of material-wind separation. Compared with the dust removal, there are many materials, and the effect of selecting the lower spin type is better. The 38, 45 and 55 centrifugal dust collectors on the market have short spiral sections, and the centrifugal separation effect of the wind material is very general. It is not suitable for large air volume and is generally used in the feed air delivery system below 5th. The unloader used in pneumatic conveying draws on the characteristics of the centrifugal dust collector and lengthens the lower rotating section to achieve a good separation effect. The general separation efficiency is about 98, and the dust content in the tail wind is small. The cyclone unloader of this structure is suitable for single-line processing capacity of 5~15th. The selection of the cyclone unloader must be matched with the air volume of the fan. If the cyclone unloader cannot effectively handle the fan air volume, a large amount of powder will be The fan is sucked away, and the load of the pulse bag filter is increased, which affects the overall processing capacity of the system.
