Embodiment Construction

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Such as figure 1 As shown, a double-rotating plate electrostatic precipitator of the present invention includes a dust collector housing (1), a fixed electric field (2), two rotary electric fields (15), (16), ash hopper (12), dust removal Brush (10), fixed electric field (2) is located at the front end of the dust collector against the air inlet (13), and the rotary electric field is located at the rear end of the dust collector against the air outlet (8). The fixed electric field is set at the front end of the dust collector because the workload of maintenance is relatively small, and the effect on the adsorption of coarse particles is better, and it is also to reduce the wear and tear on the high-investment rotary electric field; the rear end is set with two rotary electric fields. The first rotary electric field plays a key control role, so that the dust conce...

Abstract

The invention relates to an electric dust remover with double rotary polar plates. The electric dust remover comprises a dust remover shell, a fixed electric field, rotary electric fields, a dust hopper and a dust cleaning brush, and is characterized in that one or more fixed electric fields are arranged at the front end, close to an air inlet, of a dust remover body; two rotary electric fields are arranged at the rear end, close to an air outlet, of the dust remover. By the adoption of the technical, the concentration of dust entering the last-stage rotary electric field can be controlled effectively; moreover, the secondary dust re-entrainment can be prevented relatively well; the overall dust removal effect of the dust remover is improved; high-concentration dust-containing flue gas meets emission requirements easily, and key operating mechanisms work stably and reliably.

Description

technical field [0001] The invention relates to a novel double-rotating plate electric dust collector, which belongs to the field of flue gas dust removal for air pollution control. Background technique [0002] At present, most of the dust removal equipment in my country's coal-fired power plants, metallurgy, chemical industry, coal power, and building materials industries use electrostatic precipitators. Low resistance, simple and reliable use, low operating cost and no secondary pollution, but there are inherent disadvantages, one is the low efficiency of dust removal for dust with high specific resistance, and the other is the secondary pollution caused by vibrating the dust-absorbing plate. Secondary ash, the dust concentration at the outlet of the electrostatic precipitator is high, the performance is unstable, and the national environmental protection requirements cannot be met. In order to solve the above problems, as early as the late 1970s, some foreign companies be...
