The positive electrode of the electrostatic precipitator is a dust collecting electrode and is made of metal plates with different geometric shapes. The performance of an electrostatic precipitator is affected by three factors, namely dust properties, equipment configuration and flue gas flow rate. The specific resistance of dust is an index for evaluating the conductivity, which has a direct effect on the dust removal efficiency. The specific resistance is too low and dust particles are difficult to keep on the dust collecting electrode, causing it to return the air flow. The specific resistance is too high, so that the dust particles reaching the dust collecting electrode are not easy to discharge, and the voltage gradient formed between dust layers can generate local breakdown and discharge phenomena. Similar conditions can cause a decrease in dust removal efficiency. The power supply of the electrostatic precipitator consists of a control box, a step-up transformer and a rectifier. The voltage output by the power supply has great influence on the dust removal efficiency.
The existing electrostatic dust collector is connected with the mains supply, so that the energy-saving effect is poor, and in addition, the existing electrostatic dust collector is not thorough in dust collection and low in efficiency, and needs to be further improved.
