Electrostatically-enhanced electric-bag compound dust remover

Abstract

An electrostatically-enhanced electric-bag compound dust remover comprises a high-voltage power supply arranged outside a casing and a compound dust removing area arranged in the casing; the compound dust removing area comprises a forestage electrostatic dust removing area and a rear-stage bag type dust removing area, wherein the forestage electrostatic dust removing area comprises a high-voltage discharge polar line and a dust collecting pole plate; filtering bags uniformly distributed are arranged in the bag type dust removing area; conductive cage bones are arranged in the filtering bags; vertical reinforcement bars in the conductive cage bones are connected with the ground and the negative pole of a high-voltage direct-current power supply, and each two adjacent vertical reinforcement bars are opposite in polarity; a plurality of insulating rings are arranged in the vertical direction; the vertical reinforcement bars are fixed on the insulating rings. The electrostatically-enhanced electric-bag compound dust remover has the characteristics that a non-uniform electric field is added in the bag type dust removing area, so that charged dust particles are distributed non-uniformly on the surfaces of the filtering bags; meanwhile, the particles are polarized into chains through the electric field, and then the probability of collecting the particles can be increased, so that the air-to-cloth ratio can be improved, the filtration resistance can be lowered at the same time, the soot cleaning frequency can be reduced, and the dust remover has the advantages of low energy consumption and long service life.

Description

technical field [0001] The invention relates to an electric bag type composite dust removal equipment, which belongs to the technical field of industrial dust removal. Background technique [0002] With the rapid development of my country's industry, industries such as electric power, metallurgy, and chemical industry will produce a large number of dust particles every year, causing serious damage to the environment. In particular, the smoke and dust emitted by coal-fired power plants contain a large amount of inhalable particulate matter (such as PM2.5) that can enter the human body from the respiratory tract. Because the surface of these fine particles is easier to accumulate a large amount of heavy metals, it is very harmful to human health. [0003] At present, my country's dust removal equipment is mainly divided into three types: electrostatic precipitator and bag filter, and the electric bag composite dust collector developed in recent years. [0004] The electrosta...

Problems solved by technology

However, due to the unreasonable spatial distribution of the electric field intensity generated by the electrodes, the effect of the electric field force is limited.
