Problems solved by technology

After adopting the above structure, since the electrostatic precipitator is only installed at the front end of the precipitator, the dust is charged in the electric field in the electrostatic precipitator, and in the process of flowing into the bag filter, due to a certain flow distance, the charge of the dust will be lost. , or even become uncharged dust, so that the dust gap ratio on the outer surface of the filter bag is low, increasing the dust removal resistance, thus affecting the dust removal efficiency

Embodiment Construction

[0010] As shown in the drawings, the multi-compound electric bag composite dust collector of the present invention is composed of an inlet smoke box 6, a shell 2, an outlet smoke box 1, and an ash hopper 5, which are sequentially intersected in the shell 2 close to the inlet smoke box 6 along the airflow direction. An electric dust removal device 4 and a bag dust removal device 3 are provided; a small electric dust removal device 4 capable of charging is arranged between the bag dust removal devices 3 .

[0011] During industrial manufacturing, in the multi-compound electric bag composite dust collector, the housing 2 is divided into several dust removal chambers along the airflow direction, and an electric dust removal device 4 is installed in each room, and the electric field anode in each electric dust removal device 4 It consists of 2 to 3 anode plates and is supported on the upper I-beam. The lower end of the pole plate is connected with the striking rod, and one end of t...

Abstract

The invention discloses multiple electrostatic fabric filters for solving the problems of dust charge loss and the like of the prior electrostatic fabric filter. In the multiple electrostatic fabric filters, an electric dust-removing device (4) and a bag dust-removing device (3) are sequentially and crosswise arranged inside a shell (2) close to an inlet smoke tank (6) along an air flow direction. Thus, the multiple electrostatic fabric filters have the advantages of adequate dust charge, high gap rate, easy dust cleaning and the like.

Description

Technical field: [0001] The invention relates to a dust removal device, in particular to a multi-complex electric bag composite dust collector composed of an inlet smoke box, a casing, an outlet smoke box and an ash hopper. Background technique: [0002] Chinese patent CN2730484 discloses such an electric bag composite dust collector. Its structural characteristics are: it is composed of an inlet smoke box, a shell, an outlet smoke box, and an ash bucket. Electric dust removal device, flue gas flow equalization device and bag dust removal device. Chinese patent CN2000951372 discloses such an electric bag composite dust collector, which is composed of an inlet smoke box, a shell, an outlet smoke box, and an ash hopper. An electric dust collector and a bag dust collector are arranged in the shell along the direction of air flow. The upper part of the electrostatic precipitator is provided with an inlet smoke box which can make the direction of the air flow vertically downward...
