Wet electrostatic demister
Principle of wet electrostatic demister
Under the action of high DC voltage, the metal discharge wire ionizes the surrounding gas, and the dust is charged in the electric field and under the action of the electric field force It moves towards the dust collecting pole. When it moves to the surface of the dust collecting pole, it is removed as the liquid film remains.
The device applies tens of thousands of volts of DC high voltage between the anode plate (cylinder) and the cathode wire. Under the action of the strong electric field, a corona layer is generated around the corona wire, and the air in the corona layer undergoes avalanche ionization. This produces a large amount of negative ions and a small amount of cations. This process is called corona discharge. The dust ions entering the wet electrostatic demister with the process airflow collide with these positive and negative ions and are charged. The charged dust ions are charged by high-voltage static electricity. Under the action of the field Coulomb force, after reaching the two poles respectively, the charges carried by each are released, and the dust particles are collected by the cathode and anode, and are separated from the gas by flowing downward by gravity. Some of the dust particles themselves Due to its inherent viscosity, it adheres to the anode plate (cylinder) and cathode wire, and is removed by flushing.
