How To Extend The Life Of The Bag Filter?

Jan. 17, 2020

Generally, when using such equipment as a bag filter, it is important to maintain it, because its price is more expensive, and it is a very important device. If the bag filter is not maintained properly, its service life will be reduced, but in addition to the maintenance, there are many problems that everyone needs to pay attention to during normal use. So how to extend the service life of the bag filter? Next, PPC Bag Type Dust Collector Supplier will come to tell you.


Bag dust collectors are widely used in thermal power plant boiler flue gas treatment due to their advantages such as high dust removal efficiency, low energy consumption, simple process principle, and adaptability to different types of coal. In the process of using a bag filter, you need to understand the factors that affect the service life of the filter bag, so that users can take measures such as inspection, maintenance, and maintenance to improve the service life of the bag filter in a timely manner.

Factors affecting the service life of the bag filter:

1. The influence of high temperature on the filter bag. When the exhaust temperature exceeds 160°C, the temperature has a significant impact on the life of the filter bag. As the temperature rises, the life of the filter bag will gradually increase, and the filter material will be burned when the temperature is reached. Therefore, the exhaust temperature should be strictly controlled during operation, long-term over-temperature operation and sudden temperature rise in a short period of time.

2. The influence of the material of the filter bag; the material of the filter bag should be selected to block the passage of fine dust, the perforations of the fabric warp and weft threads are small, the warp and weft lines are thin, the fabric fluff is long and elastic, can cover the perforations, and has strength.

3. The influence of high temperature on the filter bag. When the exhaust temperature exceeds 160°C, the temperature has a significant impact on the life of the filter bag. As the temperature rises, the life of the filter bag will gradually increase, and the filter material will be burned when the temperature is reached. Therefore, the exhaust temperature should be strictly controlled during operation, long-term over-temperature operation and sudden temperature rise in a short period of time.

4. The impact of destructive dust removal on the filter bag. In order to keep the pressure difference of the filter bag at the design value, the fly ash attached to the surface of the filter bag should be cleaned regularly.

5. The influence of filtering wind speed on the filter bag. Filtering wind speed is an important factor in determining the performance of the dust collector. For dusty flue gas with high dust concentration, fine particles and high abrasion, the filtering wind speed should be smaller, otherwise the wind speed should be higher.


Pay attention to the following points when extending the use of Bag Type Dust Collector:

1. It adopts patented technology to produce the bag type dust collector, so that the scale can be complete. Good performance

2. At the beginning of design, it should be strong. In this way, the use time of the filter bag of the dust collector can be prolonged as much as possible;

3. There should be as few removable equipment as possible, and fewer replacement parts can prolong life;

4. Select special stainless steel materials such as round, oval and lantern as the dust collector bag cage. To do a good job in the maintenance of bag dust collectors, we must proceed from the influencing factors and take regular inspections. Lintong Boda Environmental Protection will provide you with technical support for the use of bag dust collectors to help you get out of the "green" road.


When using a bag filter, pay attention to these problems can also prevent the service life of the bag filter from being shortened. The above is the introduction of Electromagnetic Pulse Valve Manufacturer.
