Description

TECHNICAL FIELD

[0001] The present application relates to the field of pulse jet bag filter, in particular to a pulse jet bag filter maintenance method. BACKGROUND

[0002] The pulse jet bag filter is a dry physical filtration and purification device for removing dust from waste gas, which plays an important role in modern production and waste gas treatment. Dust-containing waste gas needs to be controlled as an important air pollution factor, and the pulse jet bag filter is one of the important facilities for the above-mentioned waste gas treatment. The pulse jet bag filter generally includes a shell, a plurality of filter bag assemblies are arranged in parallel in the shell, dust-containing waste gas enters the shell along the waste gas channel through the induced draft fan, the dust in the waste gas is intercepted by the filter bag assembly, the relatively pure waste gas passes through the filter bag assembly and is discharged to the surrounding environment through the exhaust port on the shell, and the dust is collected at the bottom of the shell and discharged periodically. It is suitable for capturing small, dry and non-fibrous dust, the filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by using the filtering effect of the fiber fabric. When the dust-containing gas enters the filter bag type dust collector, the dust with large particles and high specific gravity is settled down due to the action of gravity and falls into the ash bucket, and the gas containing fine dust is blocked when passing through the filter material, so that the gas is purified.

[0003] During the operation of the pulse jet bag filter, bag breakage accidents often occur. After the bag breaks, the dust removal ash often accumulates in the broken bag and flows into other surrounding bags, causing the "sausage" problem of the filter bag. Therefore, it is necessary to remove the accumulated ash in the "sausage" bag and replace the bag.

[0004] At present, during the replacement of the dust removal bag, the maintenance personnel first need to take out the bag cage from the bag, and then replace the dust removal bag. However, due to the "sausage" problem of the bag, a large amount of dust removal ash accumulates in the bag cavity, and the maintenance personnel cannot take out the bag cage, so it is necessary to remove the dust removal ash in the "sausage" bag first.

[0005] The traditional method for processing the "sausage" bag is that the maintenance personnel need to drill into the interior of the pulse jet bag filter from the maintenance manhole door set on the dust collector ash bucket, climb high and use a knife to dissect the "sausage" bag from the outside, so that the dust removal ash accumulated in the "sausage" bag leaks into the dust collector ash bucket, and then the broken bag is taken out from the dust removal ash bucket. The dust removal bag is usually ≥7-10m long, the working space is small, which is extremely unfavorable for personnel safety, and the labor load is large. The attached impurities are easy to fall off and cause secondary pollution, and the fine dust not only causes secondary pollution but also contains toxic and harmful substances in the dust removal ash, which seriously threatens the health of the maintenance personnel.

[0006] In addition, some "enema" cloth bag is not damaged, but due to the damage of the cloth bag beside it, the dust falls into it, and this part of the cloth bag can continue to be used as long as the dust in the inner cavity is effectively removed, thereby effectively saving the maintenance cost.

[0061] The dust cleaning head is selected according to the dust accumulation state in the cloth bag, which is dust cleaning head 19 or dust cleaning head 20 or dust cleaning head 21.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.
