Description

Electrostatic precipitator for uniformly atomizing corona and collecting dust

Technical Field

The utility model relates to the technical field of electrostatic dust collection, in particular to an electrostatic dust collector for uniformly atomizing dust by corona.

Background

The working principle of the electrostatic precipitator is that the high-voltage electric field is utilized to ionize the flue gas, and dust charge in the air flow is separated from the air flow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, called discharge electrode. The positive electrode is made of metal plates with different geometric shapes, called dust collecting electrodes. The performance of an electrostatic precipitator is affected by three factors, namely dust properties, equipment construction 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. These conditions all cause a decrease in dust removal efficiency.
