Introduction of DMC single pulse jet bag filter
DMC single machine pulse bag type bag filter is widely used in mining, electric furnace smelting, machinery manufacturing, chemical products, cement building materials, grain processing and other industrial and mining enterprises for bin top, bin bottom, belt conveyor and local dust source dust removal. It has the advantages of flexible design, layout, small volume, large air volume, compact structure and convenient use.
The single pulse jet bag filter is mainly composed of fan, box, ash discharge device, pulse valve, control system, etc. according to the dust range and dust concentration, the processing air volume and filtering air speed are designed to meet the emission requirements. The paint film on the surface of the box can be treated with anti-corrosion and rust prevention, which has beautiful appearance, scientific structure, convenient and reliable operation. The lower part of the single pulse bag type dust collector is directly connected with the flange on the top of the warehouse, the bin, the belt transportation and other dust raising equipment for local dust removal, and the dust is directly recovered.
Structure of DMC single pulse jet bag filter
1. Upper box: it includes a liftable cover plate (or a fastening cover plate) and an air outlet.
2. Medium box: including perforated plate, access door, filter bag, keel, venturi, etc.
3. Lower box: including pressure measuring joint, etc.
4. Injection system: including pulse controller, electromagnetic pulse valve, injection pipe and air bag
Working principle of single pulse jet bag filter
The dusty gas enters the box through the air inlet, and the purified gas filtered by the filter bag is sucked in and directly discharged by the fan. With the increase of the filtering time, more and more dust accumulates on the filter bag, which increases the resistance of the filter bag, resulting in the gradual reduction of the treatment air volume. In order to work normally, it is necessary to control the resistance within the range and clean the filter bag. When cleaning the dust, the pulse controller triggers each control valve in sequence to open the pulse valve, The compressed air in the air bag is instantly injected into the filter bag through the pulse valve to each hole of the jet pipe, and the filter bag is rapidly expanded, so that the dust accumulated on the surface of the filter bag falls off, and the filter bag is obtained. The cleaned dust falls into the ash hopper or is discharged through the ash discharge valve, so that the dust accumulated on the filter bag is periodically pulsed for ash removal, so that the purified gas can pass normally and ensure the operation of the dust removal system.
