Fixed-point dust removing device for flying dust treatment in dusting point

Abstract

The invention relates to a fixed-point dust removing device for flying dust treatment in a dusting point. The device comprises a shell (2), a centrifugal fan (5), a cyclone dust remover (4), a high-voltage electrostatic absorber (6) and a medium-effect air filter (9); the high-pressure electrostatic absorber (6) includes a closed cavity, multiple connected cathode electrodes (8), multiple connected anode dust collecting plates (7) and a dust unloading valve (11) below the closed cavity; the closed cavity is divided into multiple small cavities with opened upper and lower parts by the anode dust collecting plates (7); the cathode electrodes (8) are arranged in the small cavities like goads; multiple needle-shaped barbs are fixed on the peripheries of the goad lengths; and the anode dust collecting plates (7) are metal corrugated boards. The device has the advantages of good dust removing effect and energy conservation.

Description

technical field [0001] The invention relates to a fixed-point dedusting device for industrial and mining enterprises to disperse dust-generating points for dust treatment. Background technique [0002] At present, in the iron and steel metallurgy industry and the ore mining powder processing industry, there are various dust generation points in enterprises containing powder, fly ash or broken materials, such as stockyards, loading and unloading equipment in iron and steel enterprises , Unloading chute, transfer station, pit, ash unloading bin, etc. These dusting points are randomly scattered in various places in the factory area, and the dust pollution in the air of these workplaces is very serious. In order to solve the problem of scattered dust in the factory area of ​​iron and steel industrial and mining enterprises, most industrial and mining enterprises use color steel plates to surround the dust scene and use watering to prevent the dust from escaping. However, due to ...

Problems solved by technology

In order to solve the problem of scattered dust in the factory area of ​​iron and steel industrial and mining enterprises, most industrial and mining enterprises use color steel plates to surround the dust scene and use watering to prevent the dust from escaping. However, due to the unreasonable design of the enclosure structure and the temporary construction of color steel plates The enclosure is very simple, and the dust will still escape from various gaps, causing the dust pollution at the dust point to not be fundamentally controlled; industrial and mining enterprises also use large-scale bag dust removal systems to collect and filter scattered dust points However, on the one hand, it is not conducive to implementation because of the large investment, and on the other hand, it is not economical and reliable because the final centralized dust treatment after bagging system dust collection cannot be effectively processed.
