Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a pre-charged bag type dust removal equipment. Background Art

[0002] The flue gas of industrial furnaces contains dust and fine particles. Bag dust collectors are usually used to separate dust and fine particles from the gas to purify the flue gas to meet the requirements of environmental emission standards or the requirements of downstream processes on the dust concentration of the flue gas. When the number of fine particles in the flue gas is large, the particle size is small, or the emission standards are strict, the purification efficiency of conventional bag dust collectors cannot meet the requirements. In this context, additional pre-charging technology can be used to improve the capture efficiency, that is, first use a pre-charging device to charge the fine particles in the flue gas, and then use a bag dust collector to remove the charged dust to achieve efficiency improvement.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN203790782U, which discloses a pre-charged bag dust collector. The utility model includes a pre-charge device 1 and a bag dust collector 2. The bag dust collectors 2 are arranged in double rows in parallel. The pre-charge device 1 is arranged between the two rows of bag dust collectors 2 to form an air inlet channel for the two rows of bag dust collectors 2; the pre-charge device 1 includes a top plate 9, an inclined bottom plate 10, a discharge electrode 4, and a grounding electrode 8; the grounding electrode 8 is installed on both sides and the center of the top plate 9 and the inclined bottom plate 10, and the space formed by the top plate 9, the inclined bottom plate 10, and the grounding electrode 8 forms an air inlet channel 3, and the air inlet channel 3 is arranged between the two rows of bag dust collectors 2; a discharge electrode 4 is arranged in the air inlet channel 3, and the discharge electrode 4 is suspended in the form of an assembly through an insulating hanging porcelain bottle 5. The utility model organically combines the pre-charging device and the bag dust collector into a whole, has a compact structure, strengthens the capture effect of fine particles in the flue gas, is particularly suitable for efficiency improvement of traditional large-scale bag dust collectors, saves investment and is easy to implement.

[0004] Although the above-mentioned pre-charged bag dust collector solves the problem of low efficiency in capturing fine particles such as PM2.5 due to the lack of a pre-charging device, after the dust in the flue gas passes through the pre-charging device, the fine particles are charged and form a loose powder cake structure on the surface of the filter bag, which is loose and porous sponge-like. This powder cake structure can effectively capture fine particles in the flue gas, and then these powder cake structures remain in the dust removal equipment, making it inconvenient to clean them, reducing the functionality of the dust removal equipment, and reducing the dust removal work efficiency.
