Description

Electrostatic dust collector

Technical Field

The utility model relates to an electrostatic precipitator belongs to industrial dust collecting equipment technical field.

Background

An electrostatic precipitator is a device for treating air pollution, which can collect dust in dust-containing gas to purify the dust-containing gas. 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 negative pole is supported by metal wires with different end surface shapes, and is called a discharge motor. The positive pole is made of metal plates of different geometries and is called a dust collecting motor. 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 it has a direct influence on the dust 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.

At present, the temperature of a conventional electrostatic dust collector needs to be controlled below 80 ℃ to operate so as to prevent the body of the electrostatic dust collector from being damaged, however, the conventional electrostatic dust collector lacks the cooling capacity for flue gas and influences the service life of the electrostatic dust collector.
