Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to an air purification device based on electrostatic dust removal. Background technique [0002] Electrostatic dust removal is a kind of gas dust removal method. Dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. After dust particles and negative ions are combined with a blessing point, they tend to discharge and deposit on the surface of the anode. Electrostatic dust removal is used in metallurgy, chemical industry and other industries. To purify gas or recover useful dust particles. Electrostatic dust removal is a dust collection method that uses an electrostatic field to ionize the gas so that the dust particles are charged and adsorbed to the electrode. It has the advantages of high dust removal efficiency, large air volume purification, simple structure, small pressure loss, and long-distance operation. [...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing electrostatic precipitator, as time goes by, the dust particles accumulated on the anode plate gradually increase, resulting in the decline of the anode plate’s ability to absorb negatively charged dust particles, thereby reducing the dust removal efficiency of the device. Not only that, The air purification ability of the electrostatic precipitator is affected by the air velocity. When the air velocity of the dust-laden airflow is too high, it takes a certain time for the dust to deposit on the electrode plate after being charged in the electric field. The air velocity is too high, and the charged dust has no time to settle. At the same time, if the flow rate of the flue gas is too high, it is easy to cause the dust deposited on the electrode plate to fly again, which increases the dust content of the purified air, affects the air purification effect, and leads to the existing static electricity. Reduced practicality of dust removal and air purification devices
