How the filter bag is used is the key to its effectiveness
Filter bag is one of the most popular equipment in the purification industry and is widely used in our daily life. But as we all know, the filter bag is a kind of device to filter impurities, which needs to be replaced frequently. How to effectively extend its service life and reduce the frequency of replacement?
First of all, we should pay attention to the aging of the filter bag. Generally, aging is caused by the following reasons: hardening and shrinkage due to high temperature, reaction with acid, alkali or organic solution, and reaction with water. In case of aging, we should investigate the reasons and take corresponding measures. In another case, when the filter bag is blocked, the operating resistance will increase, which will affect the filtering effect. Usually, we will take the following measures: strengthening the ash cleaning to clear the blockage of the filter bag, replacing the filter bag or adjusting the installation and operation procedures. Finally, we should pay attention to the filter bag installation should not be too loose or too tight, too loose easy dust accumulation, too tight easy to pull out. For the replaced filter bag, it should be cleaned with compressed air first, and then checked for any damage. If any damage is found, it should be repaired or replaced in time.
