Filter bag device and dust remover

Abstract

The invention discloses a filter bag device and a dust remover. The filter bag device comprises an elastic filter bag and a bag cage arranged in the elastic filter bag, wherein the bag cage can adjustthe size of filter holes of the elastic filter bag. According to the filter bag device, by adopting the elastic filter bag, the elastic filter bag can deform, and the bag cage capable of adjusting the size of the filter holes of the elastic filter bag is adopted, when the size of dust needing to be filtered is changed, the size of the filter holes of the elastic filter bag can be adjusted throughthe bag cage to meet the filtering requirement, the universality of the elastic filter bag is effectively improved, the requirements of different dust particle sizes can be met, namely the requirements of different smoke and different coal types are met, and the dust removing effect of the dust remover is improved; meanwhile, when the elastic filter bag is deformed, a dust layer on the elastic filter bag can fall off, and the service life of the elastic filter bag is prolonged; by adjusting the pore size of the filter holes of the elastic filter bag, the filtering resistance of the elastic filter bag is reduced, the energy consumption of a fan is reduced, and the service life of the elastic filter bag is prolonged.

Description

technical field [0001] The invention relates to the technical field of dust removal, more specifically, to a filter bag device and a dust collector. Background technique [0002] At present, the dust removal equipment of power plants generally adopts electric dust collector, bag dust collector, electric bag composite dust collector, etc. Among them, the bag dust collector and the electric bag composite dust collector are favored by users because of their high dust removal efficiency and small footprint. As the core component of the electric bag composite dust collector, the filter bag is used to filter the dust not captured in the front-stage electric field area, and is the last guarantee for ultra-low dust emission. [0003] The coal burned in the power plant is good and bad. Different coal combustion produces different sizes of dust. Even if the same coal is completely burned and incompletely burned, the size of the dust produced is also different. Therefore, the particle...

Problems solved by technology

Because the filter material in the filter bag is generally made of woven mesh cloth, the pore size of the woven mesh cloth is fixed after installation, and it can only filter and remove dust for specific dust, resulting in poor versatility of the filter bag and making the dust removal of the entire dust collector difficult. less effective

[0004] In addition, after the dust collector has been running for a period of time, a large amount of dust will accumulate on the surface and inside of the filter bag. Conventional methods such as pulse injection or vibrating cannot effectively remove the agglomerated dust inside and on the surface of the filter bag, and the resistance will gradually increase. The erosion life of the dust will also be shortened, resulting in the need to replace the filter bag after 2-4 years of use
