An Overview of Dry Electrostatic Dust Precipitator

1. Working principle of dry electrostatic dust precipitator

Dry electrostatic precipitators can also be simply called electrostatic dust precipitators.

The dry electrostatic dust precipitators is composed of air inlet and outlet, shell, ash hopper and other main parts. The airflow containing pollutant particles will first pass through the air inlet and distribute the airflow evenly through the distribution plate under the action of the fan; the uniformly distributed airflow containing pollutant particles enters the electric field with a voltage of tens of thousands of volts, the cathode line electrolysis electric field The internal air charges the pollutant particles, moves to the anode plate under the action of the electric field, and finally adheres to the anode plate; the dry electrostatic precipitator vibrates the anode to shake off the particles attached to the anode plate. Collected through the ash bucket. In the airflow passing through the electric field, most of the particulate matter will be collected, and the processed airflow will pass through the trough plate to leave some large particulate matter, and finally be removed by the outlet for other processing or discharge.

The above is the main principle of dry electrostatic dust precipitator, other forms of dry electrostatic dust precipitators are improved and optimized on this basis, so that the dust removal efficiency is higher, the emission is lower, and the low emission requirements are finally achieved.

2. The advantages of electrostatic dust precipitators

Electrostatic precipitator is the most basic kind of precipitator, and it still has some advantages in some aspects. The electrostatic precipitator is relatively simple in structure and convenient to install. It does not require too many complicated piping structures. It is all composed of steel structure. The production and transportation process is also relatively safe. The electrostatic precipitator can withstand relatively high flue gas temperatures, with a limit temperature of nearly three. At 100 degrees Celsius, for example, after sintering, the flue gas can enter the dust collector electric field through the pipe for dust removal operation; the routine maintenance of the electrostatic precipitator is relatively simple and convenient, and the later investment and operation cost is lower.
