Graded efficient electric precipitator

Abstract

The invention relates to a graded efficient electric precipitator, comprising a cathode ray, a baffling plate type anode plate with a dust collection ditch; wherein the cathode ray is a tube with two symmetrical edges, a transverse section of each anode plate is folded into four folds to form two concave zones and two convex zones, concave zones of the two adjacent rows of anode plates are corresponding to concave zones of the two adjacent rows of anode plates and convex zones of the two adjacent rows of anode plates are corresponding to convex zones of the two adjacent rows of anode plates; symmetric center points of the two concave zones of the two adjacent rows of the anode plates are vertically arranged on the cathode ray, the two symmetrical edges of the cathode ray are respectively faced the concave zones of the two adjacent anode plates, multiple 'Y'-shaped bent splinters are welded on the two symmetrical edges of the cathode ray from top to bottom at uniform spacing, two bent cuspidal points at the head part of the 'Y'-shaped bent splinters are respectively faced with the two board surfaces of the concave zones of the anode plates. In the invention, the two bent cuspidal points at the head part of the 'Y'-shaped bent splinters are respectively faced with the anode board surfaces, so that critical coronal current and breakdown voltage of the cathode ray is increased, which in turn improves efficiency of dust collection; in addition, height of the two bent cuspidal points of the 'Y'-shaped bent splinters can be adjusted, requirements on dust collection of different power can be met and the application range is wide.

Description

technical field

[0001] The invention relates to a very high-efficiency electric precipitator which utilizes a high-voltage electric field to separate and collect dust suspended in gas. Background technique

[0002] Using high-voltage DC electric field to separate and capture the dust in the gas is to install cathodes and anodes arranged at intervals in a closed device, apply DC high voltage to the cathode, and form a high-voltage DC electric field with the grounded anode, and the dust-laden gas flows Over time, a corona discharge is generated between the two poles to charge the dust. Under the action of the electric field force, the charged dust moves toward the two poles and is adsorbed on the cathode and anode. The dust adsorbed on the electrodes is peeled off by vibration and falls into the The ash hopper is discharged, and the gas flowing out of the electrostatic precipitator is the clean gas after dust removal. When the electrostatic precipitator is running with electr...
