Description

An ultrasonic cleaning mechanism for a honeycomb electrostatic precipitator

technical field

The utility model relates to a cleaning mechanism inside an electrostatic precipitator, in particular to an ultrasonic cleaning mechanism for a honeycomb electrostatic precipitator.

Background technique

The dust removal efficiency of the electrostatic precipitator is high at the initial stage of operation, but as the operating time increases, dust with strong adhesion is easy to accumulate on the anode tube, and the dust accumulates and scabs, resulting in shortened and uneven distance between the two stages of the electrostatic precipitator, frequent discharge, and poor operation. Unstable, dust removal efficiency drops. At the same time, because the cathode has more burr-shaped emitters and a larger radius of curvature, the ideal corona discharge effect can be achieved. When there is a little dust on the cathode, the radius of curvature of the burr will be reduced, and the initial voltage of the corona will be increased. Reduce the safety and reliability of the electrostatic precipitator, reduce the corona discharge effect, further reduce the life of the cathode, increase the number of replacement cathodes, and eventually cause unstable operation, decrease in dust removal efficiency and waste of resources .
