Problems solved by technology

During this process, the dust particles adsorbed on the dust removal electrode plate will gradually increase. When the accumulation reaches a certain level, it needs to be cleaned, otherwise the dust removal effect of the electrostatic precipitator will be seriously affected.
[0003] At present, dust cleaning methods used in electrostatic precipitators include mechanical vibration and low-frequency sound wave cleaning, etc. This kind of dust cleaning methods will have relatively serious dust phenomenon during the cleaning process, especially the use of low-frequency sound wave cleaning The phenomenon of dust flying is particularly serious during ash removal, causing gas emissions to exceed the standard during ash removal, resulting in secondary pollution
This is a practical problem that exists in the online cleaning process of various electrostatic precipitators and cannot be effectively overcome.

Embodiment Construction

[0015] Such as figure 1 As shown, in the casing 1 of the electrostatic precipitator, there are three electrostatic fields arranged in sequence from the inlet 6 to the outlet 5. Each electrostatic field is composed of a number of dust removal electrode plates 2 arranged in parallel. Between two adjacent electrostatic fields There are corridors 3 vacated at intervals, and three electric roller shutter mechanisms 4 corresponding to each other are respectively installed on both sides of the top of the three electrostatic fields. That is to say, there are three electric roller shutter mechanisms 4 on each side of the electrostatic field, and the three electric roller shutter mechanisms 4 are adjacent to each other and arranged in a row. boards are connected. Thus, all the dust-removing electrode plates 2 in each electrostatic field are divided into three areas that can be sealed and isolated. According to the size of the electrostatic precipitator, each electrostatic field can be...

Abstract

The invention relates to an electric precipitator, designed for solving secondary dust pollution in online ash removal of electrical precipitator. The structure thereof includes that a case is internally provided with a plurality of electrostatic fields which are sequentially arranged from inlet to outlet, each electrostatic field is composed of a plurality of dust removal electrode plates which are arranged in parallel, a gallery is arranged between two adjacent electrostatic fields, and the tops of the two sides of at least one electrostatic filed of the electrostatic fields are respectively provided with an electric roller shutter which is in charge of partition isolation on the dust removal electrode plates in the electrostatic field. The electric precipitator of the invention makes the best of the original structure and layout in the electric precipitator, space volume occupying the interior of the electric precipitator is dispersive, and structure is simple, control is convenient, online ash removal without secondary dust pollution is realized, and environmental protection effect is improved.

Description

technical field [0001] The invention relates to a device for separating dispersed particles from gas by electrostatic effect, in particular to an electric precipitator. Background technique [0002] In the production process of iron and steel, metallurgy, electric power and other industries, the dust gas generated is generally purified by electrostatic precipitator. This type of electrostatic precipitator is generally provided with a number of electrostatic fields arranged in sequence from the inlet to the outlet in the casing. Each electrostatic field is composed of a number of dust removal electrode plates arranged in parallel. Between two adjacent electrostatic fields corridor. When the dust gas passes through the electrostatic precipitator, the dust particles in it are absorbed by the dust suction electrode plate, so as to achieve the purpose of purification and dust removal. During this process, the dust particles adsorbed on the dust removal electrode plate will grad...
