Coulomb electric precipitator

Abstract

The invention discloses a coulomb electric precipitator which comprises a dedusting tank body, wherein the two ends of the dedusting tank body are provided with an air inlet tank and an air outlet tank; one side, which is adjacent to the air inlet tank, of the dedusting tank body is provided with a front electric field which comprises fixed polar plates and corona discharge electrodes; the fixed polar plates and the corona discharge electrodes are arranged alternately; the fixed polar plate is provided with fixed polar plate air vents through which smoke passes; an electric field channel is formed between adjacent fixed polar plates; a rear electric field comprises movable polar plates and the corona discharge electrodes, and the movable polar plates and the corona discharge electrodes are arranged alternately; the movable polar plates are connected with an elevator mechanism for driving the movable polar plates to move up and down; rotary brushes are arranged below the movable polar plates, and the corona discharge electrodes are provided with negative electrode rappers; ash buckets are arranged below the rotary brushes; and the movable polar plates are provided with movable polar plate air vents through which the smoke passes, and an electric field channel is formed between adjacent movable polar plates. The Coulomb electric precipitator can effectively prevent secondary dust flying in the dedusting process, maintains stable and high dedusting efficiency and lowers the cost.

Description

technical field [0001] The invention relates to a high-voltage electrostatic precipitator for industrial dust particles. Background technique [0002] The current known electrostatic precipitator, its circuit principle is: the negative end of the DC high-voltage power supply output end is electrically connected to the corona discharge electrode, the positive end of the output voltage is electrically connected to the dust collection plate and grounded, and the corona discharge electrode and the dust collection electrode are electrically connected to each other. The plates form an electrostatic field. [0003] The dust-collecting plate in the electric field adopts a shielded flat plate structure, that is, a vertically suspended flat plate-like closed fixed plate, and the upper or lower part is hammered to remove the dust accumulated on the plate. The way the flue gas flows in the electric field is to make the flue gas go straight forward in the channel parallel to the dust co...
