High-efficiency purification electrostatic dust collector

Abstract

The invention relates to a high-efficiency purification electrostatic dust collector, aiming at solving the problem that the dust removal efficiency is reduced, caused by reverse corona and secondarydust rising. The high-efficiency purification electrostatic dust collector comprises a gas inlet, a gas outlet, a dust collection plate, a discharging wire and an ash bucket, wherein the dust collection plate is provided with an ash cleaning device; ash cleaning boxes with a special design are adopted and are used for squeezing dust swept by an ash cleaning brush at the top of the box body, so that the secondary dust rising is avoided; two ash cleaning boxes form one group, and form a loop through a rope; when one ash cleaning box is ascended, the other ash cleaning box is descended to clean ash. The ash cleaning brush is designed to keep vertical with the dust collection plate in an ash cleaning process; when the ash cleaning brush is ascended to be reset, a brush head is folded, so thatthe service life is prolonged. According to the dust collector provided by the invention, the disadvantages of a conventional electrostatic dust collector that the specific resistance is high, ultrafine dust and high-viscosity dust are difficult to collect and clean, the secondary dust rising is easy to cause and the like are overcome, and the defects of a bag dust collector that the equipment resistance is great, the operation cost is high, the working amount of daily maintenance is great, high-temperature and high-humidity flue gas is difficult to treat and the like are also made up; the high-efficiency purification electrostatic dust collector is simple in structure, high in ash cleaning efficiency, low in cost and easy to maintain.

Description

technical field [0001] The invention relates to the field of electrostatic precipitators, in particular to an efficient purification electrostatic precipitator. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection and the country's increasing emphasis on environmental protection, the pollutant discharge standards are also increasing. At present, many electrostatic precipitators used in various industries have not reached the new dust discharge standards and are facing renewal and remodel. [0003] The problems existing in conventional electrostatic precipitators are mainly the back corona caused by high specific resistance dust and the secondary dust caused by rapping, which greatly affects the dust removal efficiency of electrostatic precipitators, which is also the main problem faced by conventional electrostatic precipitators at present. technical bottleneck. [0004] High specific resistance dust is likely to c...
