【Abstract】:

Bag type dust removal filter bag is often used in dust removal equipment of a kind of accessories, and such an accessory can be said to be an important part of the whole dust removal device, with such a device, dust removal equipment can better play their role.

Bag type dust filter bag can not work alone, its work is to rely on dust removal equipment, and what we need to do is to install such a dust removal filter bag correctly in the dust removal equipment, it can play its own dust removal role.
Of course, just a simple installation seems not all of the work, to use it, we also need to know how to operate the dust removal equipment, so that the dust removal equipment and dust bag with the work, you can achieve the purpose of dust removal. After that, we need to say that in the correct use of dust filter bag, we also need to know the maintenance of dust filter bag, the better the maintenance work, then we can get more from it.
Tips to protect bag type dust filter bag:
1, filter wind speed: bag filter wind speed is too high, is the main reason for the damage of dust filter bag. In recent years, in order to increase the benefits, the ministry has improved the filter wind speed in the design of bag dust collector. In a short time, the user has no significant response, but the service life of the filter bag has been greatly shortened. Instead of saving money for the customer, this has brought a huge economic burden and wasted time.
2, the use of temperature accurately select the appropriate temperature of dust removal filter bag, is the key of dust removal filter bag. If the temperature is too high, the selected dust removal filter bag should exceed the normal operating temperature. If the filter bag is light, the service life will be shortened, and if it is serious, it will be burned in a short time. Therefore, when selecting filter bag, the inlet temperature of dust collector should be measured and calculated, and the corresponding filter bag should be selected.
3. The selection of dust medium bag dust filter bag fabric depends on the dust nature of the dust, and it is necessary to consider whether the dust is rich in acid, alkali or corrosive substances. According to the nature of the dust selection of suitable filter material, so that the filter bag can be normal adsorption dust, and does not affect its service life.
Dust bag is an important part of the cloth bag dust collector, dust bag is equivalent to the heart, other accessories to assist it to get the dust cleaning effect, when we find that the dust removal effect of the dust collector is not ideal, it is likely to dust bag aging. For the aging of dust removal filter bag, the aging of dust removal filter bag is mainly analyzed for the following reasons:
1. The dust removal filter bag is blocked.
After blockage, the resistance will be increased and the cleaning interval will be shortened. These factors will accelerate the aging of the dust filter bag. For the aging problem of dust filter bag, we generally take the following 4 measures:
(1) New technology and old cloth bags should not be mixed.
Avoid frequent replacement and maintenance with different damage time and affect the normal work of dust removal equipment.
(2) tightness of dust filter bag.
Should not hang too loose or too tight, too loose easy dust, too tight easy to pull bad.
(3) temporarily strengthen the cleaning of ash.
To prevent the dust filter bag blockage.
(4) Correct selection of dust filter bag.
Select the dust removal filter bag suitable for dust condition to avoid hardening and shrinkage of cloth bag due to abnormal high temperature.
2. Abnormal operating temperature.
If the temperature is too high, it will cause the dust filter bag to be burned black and burned. If the temperature is low, it will speed up the dedew phenomenon of the dust removal filter bag, which leads to the phenomenon of pasting the bag easily. Over time, the dust removal filter bag will be aging and even affect the service life.
3, acid base imbalance.
Dust bag and acid, alkali contact will cause dust bag corrosion, so a long time acid-base imbalance, will also lead to dust bag aging.
4. Moisture in smoke.
Some dust removal filter bags and water contact for a long time will be separated, such as polyester dust removal filter bag, so the water separation of dust removal filter bag is easier to aging.
