When the bag blockage occurs, the resistance increases, which can be shown by the increase in the reading of the differential pressure meter. Bag clogging is the main cause of bag wear, perforation, shedding and other phenomena. Causes of dust bag blockage, according to the table for inspection and maintenance.

I Generally take the following measures

1.  Temporarily strengthen the dust cleaning to eliminate the clogging of the bag.
2. Partial or complete replacement of bags.

3. Adjust the installation and operating conditions.

II Measures to prevent clogging of dust bag
Bag wetting Leakage of dust collector box and other parts Eliminate water leakage, drying, repeated dust cleaning.
Dust wet Identify the cause Eliminate the root cause, repair.
Insufficient bag tension Suspension method Adjustment, repair.
Clogging of the lower part of the bag Identify the cause Adjustment, repair.

Bad installation of cloth bag Installation method Adjustment, repair.

III Poor ash cleaning
1. The ash hopper is not sealed.
2. Ash cleaning mechanism failure.
3. Insufficient backblowing air volume.

4. Insufficient blowing pressure adjustment, repair.

IV Bag shrinkage to identify the cause
1. The filter speed is too high, air volume, adjust.
2. The dust filter bag breakage. The shape of the bag and the bag installation methods and institutions to determine the location of the bag is prone to breakage, according to which inspection and repair can be carried out. But mainly caused by the following reasons bag breakage, such as the occurrence of breakage phenomenon can refer to the following table for inspection.
(1) ash cleaning cycle is too long adjustment, shortening filter bag aging to identify and eliminate the cause
(2) dust cleaning time is too long adjustment, shorten the filter bag due to heat hardening to identify and eliminate the cause
(3) Insufficient bag tension adjustment, strengthening burned Re-research the filter bag material
(4) the bag is too loose adjustment, leakage of dust to identify and eliminate the cause

(5) bad installation of bags adjustment, reinforcement too high filter speed adjustment to reduce

V Dust bag aging
Mainly due to the following reasons, the cause must be investigated, take measures to eliminate and replace the dust filter bag.
1. Due to abnormal high temperature and hardening shrinkage.

2. Due to the contact reaction with acid, alkali or organic solvent vapor.

3. Reaction with moisture.

VI The filter cloth should not be hung too loose or too tight, too loose easy to accumulate dust, too tight easy to pull bad.

VII The new process should not be mixed with the old bags to avoid damage to different times affect the normal work of dust removal equipment.

VIII Replace the down cloth bag, first blow clean with compressed air, and then check whether there are holes, there are holes repaired and left for replacement. Such as dust paste bags, rinse with water, cool and dry, and then set aside for replacement.
Anhui Yuanchen Environmental Protection Technology Co., Ltd ("Yuanchen Technology") is a high-tech enterprise integrating R&D, production and sales of dust removal bags and denitrification catalysts. The dust bags (mainly PPS, PTFE, P84 and composite series filter materials) and SCR denitrification catalysts have been widely used in cement, steel, glass kilns, waste incineration power generation, biomass power generation, non-ferrous metal smelting and other industries. In the future, Yuanchen Technology will be guided by "becoming the guardian of global ecological environment", always rooted in environmental protection, and insist on the great cause of guarding the blue sky and white clouds. Leveraging on the national ecological civilization construction pattern, we will continue to deepen technology, optimize management, strengthen brand, refine industry and solidify advantages, and create synergistic value for industry through comprehensive and integrated governance and services.
