As the requirements of the national environmental protection policy become stricter, and the dust content of export emissions is required to be close to ultra-clean emissions, dust filter bags have become more commonly used dust removal environmental protection products, and their dust removal rate makes them popular in industrial production. , The reasons for this aging phenomenon, the specific influencing factors are ① hardening and shrinkage due to abnormal high temperature, ② due to contact reaction with acid, alkali or organic solvent vapor, ③ reaction with moisture, ④ filter bag clogging, resistance after clogging will increase, and the cleaning interval will be shortened, these factors will accelerate the aging of the dust collector fabric bag.
There are several reasons:
1. The temperature of the working condition is abnormal. If the temperature is too high, the dust collector bag will be burned black and burned; if the temperature is low, the condensation phenomenon of the dust collector bag will be accelerated, which will lead to the occurrence of sticky bags.
Like, over time, the dust collector bag will age, and even affect the service life.
2. The acid-base imbalance, the contact of the dust collector bag with acid and alkali will cause the dust collector bag to be corroded, so the long-term acid-base imbalance will also cause the dust collector bag to age.
3. Moisture in the flue gas, some dust collector bags will be decomposed if they are in contact with moisture for a long time, such as dust collector bags made of polyester, so the dust collector bags decomposed by water are easy to age.
4. The filter sleeve is blocked. After the blockage occurs, the resistance will increase, and the cleaning interval will be shortened. These factors will accelerate the aging of the filter socks.
Dust collector bag is a commonly used dust removal tool today, but improper use will cause premature aging and failure. Therefore, careful selection of materials and reasonable use are the keys to ensuring the "longevity" of dust collector bags. Blockage, because the dust collector fitlter sock becomes easy to wear, perforate and fall off after it is blocked. In order to solve the blockage, it is necessary to shorten the cleaning interval and strengthen the cleaning strength, which will easily cause damage to the dust collector bag and accelerate aging. Rational use of dust collector filter sleeves.
