Description

Pulse bag type desulfurization and denitrification dust collector for easy dust sliding

technical field

The utility model relates to a dust collector, in particular to a pulse bag type desulfurization and denitrification dust collector which is convenient for dust to fall, and belongs to the technical field of cloth bag dust collectors.

Background technique

A bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. The action settles down and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified.

A bag filter is a dry dust filter. After the filter material is used for a period of time, due to the effects of sieving, collision, retention, diffusion and static electricity, a layer of dust accumulates on the surface of the filter bag. As the dust accumulates on the surface of the filter material, the efficiency and resistance of the dust collector increase accordingly. , When the dust on the surface of the filter bag continues to increase, causing the resistance of the equipment to rise to the set value, the time relay (or differential pressure controller) outputs a signal, the program controller starts to work, and the pulse valves are opened one by one, so that the compressed air passes through the nozzle to filter The bag is sprayed to clean the dust, so that the filter bag suddenly expands. Under the action of the reverse air flow, the dust attached to the surface of the filter bag quickly escapes from the filter bag and falls into the ash hopper. Some dust will be blocked in the gaps without belts, resulting in incomplete ash fall each time, so that the filtering effect and work efficiency will decrease during subsequent dust removal.
