Adjustable converter electrostatic precipitator

Abstract

The invention discloses an adjustable alternating-current electric dust collector. By the adoption of the adjustable alternating-current electric dust collector, the problem that according to an existing electric dust collector, the back corona phenomenon and severe secondary flying are prone to happening to high-specific-resistance (ultrafine) dust in smoke, and consequentially the dust collection efficiency is affected is solved. According to the adjustable alternating-current electric dust collector, an adjustable electric field which can change the advancing path of airflow is installed in a shell (9), and the electric field is divided into a plurality of small electric fields (8); an airflow distribution device (6) is installed between every two adjacent small electric fields (8); the multiple small electric fields (8) are connected with independent adjustment mechanisms (5) respectively; various different airflow advancing paths can be formed in the electric field by changing the inclination angles of anode plates (2) in the small electric fields (8).

Description

technical field [0001] The invention relates to an electric precipitator, in particular to an adjustable variable current electric precipitator composed of a flue gas inlet, a casing, an ash hopper and a flue gas outlet. Background technique [0002] At present, such an electrostatic precipitator is disclosed in the market. Its structural features are: it includes a flue gas inlet, a shell, an ash hopper, and a flue gas outlet. , an ash hopper is installed under the casing, a plurality of anode rows are arranged in the casing, and a plurality of cathode wires are arranged between two adjacent anode rows. After adopting this structure, the flue gas with dust The inlet enters the casing, and then the anode plate and cathode line installed in the casing are charged and dust collected. Since the flue gas moves in a straight line in the casing, it is easy to cause the high specific resistance (ultrafine) dust in the flue gas to have a reverse corona phenomenon. And the larger se...
