When choosing a multi bag filter housing, several important factors need to be considered to ensure that you choose the product that suits your specific filtration needs. There are various choices in the market, and making a decision can be overwhelming. Therefore, we have compiled this selection guide to help simplify the process and ensure that you choose the best multi bag filter housing for your application.
1. Inlet and outlet diameter:
The selected filter inlet and outlet diameter should not be less than the inlet diameter of the matching pump, usually consistent with the inlet pipe diameter to avoid excessive fluid resistance.
2. Nominal pressure:
Determine the pressure rating of the filter based on the maximum working pressure that may occur in the filtering pipeline, ensuring that the equipment can safely withstand system pressure.
3. Filtering accuracy (number of pores):
Select the appropriate number of filter bag pores based on the size of the impurities to be intercepted and the process requirements. Different specifications of filters can intercept particles of different sizes.
4. Material:
The material of the bag filter should match the material of the connected process pipeline, and materials such as cast iron, carbon steel, low-alloy steel, or stainless steel can be selected according to the actual working conditions.
5. Number of filter bags and filtration area:
Select the appropriate number of filter bags and filtration area according to the processing capacity requirements. The more bags there are, the larger the diameter, and the corresponding processing capacity is enhanced.
6. Resistance loss:
Considering the pressure loss generated during the filtration process, for water bag filters, the pressure loss at rated flow rate is generally calculated to be 0.52-1.2kPa, which needs to be considered in the design.
7. Medium characteristics:
If the medium has high viscosity or contains a large amount of hard impurities, it may be necessary to adjust the equipment selection, such as choosing more wear-resistant filter bag materials or increasing the filtration area.
8. Convenience of maintenance:
Considering the convenience of replacing and cleaning filter bags, if production continuity is strong, a design that facilitates quick replacement of filter bags should be selected to reduce downtime.
9. Flow rate:
Determine the maximum and average flow rates, select filters with corresponding diameters, and ensure sufficient processing capacity.
Temperature range: The temperature of the filter medium may affect the selection of filter materials, and it is necessary to confirm that the filter can operate within the expected temperature range.
10. Chemical compatibility:
Confirm the chemical compatibility between the filter material and the filter medium to avoid corrosion or reaction
