Background
The working principle of the electrostatic dust collector is that a high-voltage electric field is utilized to ionize smoke, and dust charges in airflow are separated from the airflow under the action of the electric field. The cathode is made of metal wires with different cross-section shapes, and is called a discharge electrode. The positive electrode is made of metal plates with different geometric shapes, and is called a dust collecting electrode. The performance of an electrostatic precipitator is influenced by three factors, namely the nature of the dust, the equipment construction and the flow rate of the flue gas. The specific resistance of the dust is an index for evaluating the conductivity, and has a direct influence on the dust removal efficiency. The specific resistance is too low, and dust particles are difficult to retain on the dust collecting electrode, so that they are returned to the air flow. The specific resistance is too high, the dust particle charges reaching the dust collecting electrode are not easy to discharge, and the local breakdown and discharge phenomena are generated by forming a voltage gradient between dust layers. Both of these cases cause a decrease in dust removal efficiency.
Dry electrostatic precipitators are one type of electrostatic precipitator. Electrostatic dust collection is a dust collection method in which gas is ionized by an electrostatic field to electrically adsorb dust particles to an electrode. The dust-containing gas is electrically separated into positive ions and electrons when passing through a high-voltage electrostatic field, the electrons run to the positive electrode and encounter dust particles, and the dust particles and the electrons are combined to be charged negatively and then adsorbed to the surface of the positive electrode to be collected.
