Common application problems with filter bags

High-temperature dust bag filter cloth filter bag factory technical staff detailed introduction to common application problems:.

1. When to replace the filter bag?

There are two ways to determine when to replace the filter bag in practical applications.
1) completely in accordance with experience to roughly determine the time of replacement.
2) In the bag filter inlet and outlet pipe are installed with a pressure gauge, the pressure difference shown by the front and rear pressure gauge to determine the time to replace the filter bag, the general filter bag can withstand the pressure difference of about 0.5 to 1kg/cm2, when the pressure difference reaches this range, the filter bag should be replaced in time to avoid the bag rupture, affecting the filtering effect, do not lose a lot because of small.

2. Filtration step by step

Bag filter can be installed in series to achieve step-by-step filtration.
If installed in the front of the filter machine for high-precision filtration, it can significantly reduce the cost of filtration. Likewise, sand filtration and other filtration methods can be combined with bag filtration, thus further improving the quality of filtration and reducing the cost of filter bag consumption.
Combining self-cleaning machine, centrifugal and bag filter, we can use them individually or in tandem with other principles of filtration to achieve the desired effect.

3. How to achieve uninterrupted filtration?

Bag filter installed in parallel can ensure the continuity of filtration, or increase the flow rate, as shown in the figure parallel installation, alternately replace the filter bag, you can maintain continuous filtration.
