Technical Field
[0001] This utility model relates to the field of composite electric field electrostatic dust removal technology, and in particular to a composite electric field electrostatic dust removal device. Background Technology
[0002] Electrostatic dust removal is a method of gas dust removal. When dust-laden gas passes through a high-voltage electrostatic field, it is electrically separated. Dust particles combine with negative ions and become negatively charged. They then tend to discharge and deposit on the anode surface. It is used in metallurgical, chemical and other industries to purify gases or recover useful dust particles. It is a dust collection method that uses an electrostatic field to ionize the gas, thereby charging the dust particles and adsorbing them onto the electrodes.
[0003] The working principle of an electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas. The dust in the airflow becomes charged and separates from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes and is called the discharge electrode, while the positive electrode is made of metal plates with different geometric shapes and is called the dust collection electrode.
