Asymmetric electrostatically enhanced electrostatic bag-coupled precipitator

Abstract

The invention discloses an asymmetric electrostatic reinforced electric bag coupling dust collector, which comprises an inlet flue, a casing, an ash hopper, a clean air chamber and an outlet flue. At least two electric field channels and a bag area are arranged in the shell, and the inlet flue is connected with the electric field channel and the bag area in turn. The electric field channel includes a non-porous anode plate for generating an electric field, a folded anode plate and a cathode wire frame arranged therein, and the pocket area is arranged between the two electric field channels. The folded anode plate is shared according to the electric field channel and the pocket area. The folding anode plate is provided with a number of folding slits which can communicate with the electric field channel and the cloth bag area, so that the air flow can pass through the folding slits in a bypassing manner. A number of filter bags are arranged in the cloth bag area, and a separation bucket is arranged at the bottom. The separating hopper is located on the top of the ash hopper, and the bottom of the separating hopper forms an ash discharge channel that communicates with the ash hopper. The upper part of the ash discharge channel is provided with a star-shaped ash discharger or a middle partition. The invention has the advantages of high dust removal efficiency, reduced bag load, extended life of the cloth bag, and the like.

Description

technical field [0001] The invention relates to an asymmetric electrostatic reinforced electric bag coupling dust collector, which belongs to the technical field of dust removal. Background technique [0002] In recent years, as the country continues to promote the in-depth removal of air pollutants, composite electric bag dust removal technology has become one of the main technical routes to achieve ultra-low emission of soot due to its long life and high efficiency. Among them, the embedded compact composite electric bag technology utilizes the staggered arrangement of the electrostatic area and the cloth bag area to realize the coupling of the electrostatic area and the cloth bag area, so as to achieve high filtering wind speed, low resistance and efficient operation. In order to improve the dust removal efficiency of the electrostatic area, the prior art has adopted methods including a front electrostatic dust removal area without openings, opening holes on the dust coll...

Problems solved by technology

However, the effect is not good in actual operation. First, the airflow at the bottom of the electric field area and the bag area is short-circuited; second, the holes on the dust collection plate make the particles of this structure insufficiently charged, and the dust collection area is too small, resulting in static electricity. The dust removal efficiency cannot be effectively improved, increasing the filter load of the bag, resulting in increased resistance, and ultimately affecting the dust removal efficiency and other issues
