What are the common questions in the use of bag filters?

In terms of sewage treatment, the bag filter can achieve a precision of 1 micron, and has the characteristics of small size, large processing capacity and energy saving. However, many people will encounter many problems in daily use, so let's take a look with the editor!

First,When to replace the filter bag?

There are two methods in practice to determine when to replace the filter bag

1. Roughly determine the time of replacement according to experience.

2. Pressure gauges are installed on the inlet and outlet pipes of the bag filter. The time to replace the filter bag is determined by the pressure difference displayed by the front and rear pressure gauges. Usually, the acceptable pressure difference for the filter bag is 0.5~1kg/cm2 When the pressure difference reaches this range, the filter bag should be replaced in time to prevent the filter bag from breaking and affecting the filtering effect.

Second,Can the series device complete the step-by-step filtration?

The series device can complete the step-by-step filtration.

If the device is used at the front end of the high-precision filter, the cost of filtration can be greatly reduced. In the same way, filtration methods such as sand filtration can also be combined with bag filtration, which can then improve filtration quality and reduce the cost of filter bags.

Combining self-cleaning filters, centrifugal and bag filters, it can also be used in series with other filters to achieve the desired effect.

Third,How to complete uninterrupted filtering?

The parallel bag filter can ensure the continuity of filtration, or increase the flow, as shown in the figure in parallel, replace the filter bag, you can maintain continuous filtration.

The above are some common questions in the use of bag filters, I hope to help you.
