Novel high-voltage pulse power supply applied to electric precipitation

Abstract

The invention discloses a novel high-voltage pulse power supply applied to electric precipitation. The high-voltage pulse power supply comprises a rectifier, an inverter and a transformer, wherein the inverter comprises a motor, two input electric brushes and two output electric brushes, wherein a commutator and two output electrodes are arranged on a rotation shaft of the motor; the commutator is a sleeve ring which is fixed on the rotation shaft and rotates together with the rotation shaft; the commutator is provided with a pair of conductive blocks; an included angle of 180 degrees is formed between the conductive blocks; the two input electric brushes are in contact with the commutator and are opposite to each other; the two conductive blocks are communicated with the two output electrodes respectively; the two output electric brushes are communicated with the two output electrodes respectively. According to the high-voltage pulse power supply, the rectifier inputs direct current, namely the polarity of the current of the input electric brushes is stationary; the conductive blocks continuously rotate around the motor, so that the conductive blocks are in contact with different input electric brushes, thus the alternating current can be led out of the output electric brushes. The inverter adopting the manner is free of electronic devices; all the loss only comprises circuit loss and motor loss; the energy efficiency ratio is greatly increased.

Description

technical field [0001] The invention relates to the technical field of electrostatic dust removal, in particular to a power supply for electrostatic dust removal. Background technique [0002] The working principle of the electrostatic precipitator is to use the high-voltage DC uneven electric field to ionize the gas molecules in the flue gas, generate a large number of electrons and ions, move to the poles under the action of the electric field force, and encounter the dust particles in the air flow during the movement. It is charged, and the charged dust is separated from the airflow under the action of the electric field force and moves to the polar plate or polar line with the opposite polarity. When the charged dust reaches the polar plate or polar line, it is adsorbed on the polar plate or polar line by electrostatic force, and passes through The rapping device makes the dust fall into the ash hopper to purify the flue gas.
