Abstract

The invention relates to an electrostatic dust remover with a movable electrode plate. A fixed anode plate and a cathode wire are respectively arranged in each of a first electric field and a second electric field, and a movable electrode plate dust removing device is arranged in a third electric field and consists of a driving shaft (7), a driven shaft (10), a chain (11) and a movable electrode plate (8), a pair of steel wire dedusting brushes (14) rotating in opposite directions are arranged at two sides of the lower part of the movable electrode plate and matched with the movable electrode plate, the upper part of the movable electrode plate dust removing device is provided with an upper electrode plate guide frame (11a) and the lower part of the movable electrode plate dust removing device is provided with a lower electrode plate guide frame (11b). The electrostatic dust remover has the advantages that an integrated fastened-type anode plate is applied to each of the first electric field and the second electric filed, the top parts and side parts of the first electric field and the second electric filed are in a working mode of vibrating and hitting coexistence, thereby ensuring the dedusting capability of a previous-grade electric field; and the movable electrode plate dust removing device is applied to the third electric field, thereby thoroughly eliminating the anti-corona phenomenon which is very common in a conventional dust remover, and solving a technical difficulty that the conventional dust remover can hardly remove high-viscidity dust.

Description

technical field

[0001] The invention relates to a novel mobile plate electrostatic precipitator, which belongs to the field of flue gas dedusting equipment for air pollution control. technical background

[0002] At present, most of the dust removal equipment in my country's coal-fired power plants use electrostatic precipitators. Normal operation under atmospheric humidity conditions. However, the conventional electrostatic precipitator is greatly affected by the combustion medium and the operating conditions of the boiler, and changes in the specific resistance and particle size of the dust seriously affect the dust removal efficiency of the electrostatic precipitator.

[0003] In order to solve the above problems, Hitachi proposed the technology of using the mobile plate in the electrostatic precipitator, which can effectively solve the above problems, but in the actual use of the mobile plate, there are still some shortcomings, such as the front stage electric field anod...
