Abstract

The invention discloses a novel environment-friendly electrostatic dust collector and application thereof. A pole plate mounting hanging beam is mounted on a main frame in the dust collector. A positive discharge and dust collection integrated pole plate and a negative discharge and dust collection integrated pole plate are mounted on the pole plate mounting hanging beam by hoisted positive and negative discharge and dust collection integrated pole plate insulators. The power supply positive high-voltage output of a dual-output high-frequency soft stable power supply is connected with the positive discharge and dust collection integrated pole plate, the power supply negative high-voltage output end of the dual-output high-frequency soft stable power supply is connected with the negative discharge and dust collection integrated pole plate, and the power grounding end is connected with the grounding end of a dust collector shell. The dust of the positive and negative discharge and dust collection integrated pole plates is removed by a brush roller in an up-and-down rotating mode.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and relates to a novel environment-friendly electrostatic precipitator and its application, and more specifically relates to an electrostatic precipitator with dual power supply, discharge and dust collection integrated pole plate, and brush roller dust removal. Background technique [0002] Electrostatic precipitator is a kind of flue gas dust removal method. The electric field of the dust collector is mainly formed by the cathode of the discharge burr wire and the anode of the dust collecting plate. When the dusty flue gas passes by, the dust particles and negative ions are combined with negative charges, and tend to the surface of the anode to deposit. At present, the common electrostatic precipitator basically adopts the method of hanging the cathode line to discharge and the anode plate to collect dust; while the dust on the anode plate and cathode line is rapped or sound vibration m...
