Principle: dusty gas through the high-voltage electrostatic field is electrically separated, dust particles and negative ions combined with negatively charged, tend to the anode surface discharge and deposition.
Under the action of the electric field, the free ions in the air to move to the poles, the higher the voltage, the higher the electric field strength, the faster the movement of ions. As a result of the movement of ions, a current is formed between the poles.
In the beginning, the free ions in the air is less, the current is less. After the voltage is increased to a certain value, the ions near the discharge electrode gain higher energy and speed, and when they hit the neutral atoms in the air, the neutral atoms break down into positive and negative ions.
Because of the chain reaction, the number of ions moving between the poles greatly increased, high voltage capture incidental bacterial particles, instantaneous conductive breakdown of the cell wall composed of proteins, to achieve the killing of bacteria adsorption and dust removal.

Precautions for the operation of the electric dust collector:
1, the electric dust collector shell, anode plate, rectifier transformer, control cabinet, power cabinet, power distribution cabinet, etc. should be well grounded.
2, operation is prohibited near the rectifier transformer high-voltage part, high-voltage isolation switchgear should be padlocked, and equipped with the necessary fire fighting equipment.
3, the electric precipitator before power supply, the operator should be with the maintenance personnel **** with the inspection to confirm that no staff and debris inside the electric field, close all the manhole door before power supply.
4. It is strictly prohibited to touch the exposed part of the running or standby energized equipment with hands, and it is strictly prohibited to operate the switch or button with wet hands.
