Electrostatic precipitator; The main method is to use a high-voltage electric field to ionize the flue gas, and the dust in the airflow is charged and separated from the airflow under the action of the electric field. The power supply of an electrostatic precipitator mainly consists of a control box, a step-up transformer, and a rectifier. The impact of power supply voltage on dust removal efficiency.

Compared with other dust removal equipment, electrostatic precipitators consume less energy and are mainly suitable for removing dust particles of 0.01-50 μ m from flue gas. They can also be used in situations where the flue gas temperature is high and the pressure is high. Practice has shown that the larger the amount of flue gas processed, the more economical the investment and operating costs of using electrostatic precipitators.

An electrostatic precipitator is a device that uses high-voltage electrostatic principles to purify dusty gases. After applying high-voltage direct current between the anode and cathode, a high-voltage electrostatic field is formed. The gas ionizes under the action of the electric field force, producing a large number of electrons and ions. When the dust containing gas enters the electric field, the dust particles combine with these electrons and ions, making the dust particles charged. Under the action of electric field force, charged dust particles tend towards electrodes with opposite electrical properties, and then release charges on the electrodes and deposit on them. When the dust deposits to a certain amount, it falls into the ash hopper through the action of the vibration device, and the purified gas from which the dust particles are removed is discharged into the atmosphere through the electric field.

When installing an electrostatic precipitator, some issues need to be noted:

Before installing the lower platform foundation of the dust collector, check and confirm the requirements of the acceptance design drawings to install the various components of the electrostatic precipitator. Based on the confirmed acceptance foundation, determine the center installation benchmark of the electrostatic precipitator and use it as the installation benchmark for the anode cathode system.

Check the flatness, column spacing, and diagonal error of the basic plane.

Thirdly, inspect the shell components and correct any deformation during transportation, installing them layer by layer from bottom.
