Electrostatic dust remover for continuously winding and moving dust collecting plates

Abstract

The invention provides an electrostatic dust remover for realizing flue gas cleaning by continuously winding and moving dust collecting plates. The electrostatic dust remover comprises a dust remover, wherein a dust exhaust apparatus is arranged at the dust remover, discharge electrodes and dust collecting electrodes are arranged in a housing of the dust remover, and the dust collecting electrodes are flexible and strip-shaped dust collecting plates; and the dust collecting plates are wound on guide rolls, the guide rolls comprise driving guide rolls and induction guide rolls, multiple induction guide rolls are divided into two layers and are arranged in equidistant and parallel manners, the dust collecting plates are repeatedly and continuously wound on the up-down corresponding induction guide rolls, the discharge electrodes are arranged in gaps between adjacent two dust collecting plate arrays, the driving guide rolls are mounted at two sides below the induction guide rolls in parallel, and a dust removing device for cleaning the dust collecting plates is further mounted between the driving guide rolls. According to the electrostatic dust remover for continuously winding and moving the dust collecting plates, the structure is simple, the dust collecting area is increased, the dust removing effect is improved, the ash removal is facilitated, the maintenance is free, and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of electrostatic precipitators, in particular to an electrostatic precipitator (ESP) capable of purifying flue gas by continuously winding a moving dust collecting plate. Background technique [0002] Electrostatic precipitator technology has been widely used. Generally, the electrostatic precipitator used in industry, the dust adsorbed on the fixed dust-collecting electrode is removed by frequent vibration, which not only has a complex structure, but also consumes a lot of power, and there is a problem that the dust-collecting electrode does not fully remove the dust and affect the dust-removal efficiency. . The air purification device of the air conditioner in daily use needs to be manually removed and cleaned regularly, which is time-consuming and laborious, and also affects the ventilation effect. [0003] The mobile dust removal plate, originally developed by Hitachi, Japan, is used to improve the dust collecti...

AI Technical Summary

Problems solved by technology

[0003] The mobile dust removal plate, originally developed by Hitachi, Japan, is used to improve the dust collection efficiency of high specific resistance dust. It is an annular tank belt structure hinged by rigid metal plates. A dust removal device is composed of multiple sets of tank belts, and each tank belt has a Independent rotation and cleaning device, complex structure suitable for large electrostatic precipitator

Later, some manufacturers replaced rigid tank belts with flexible fabrics. The Ohio State University of the United States conducted corresponding research on the dust collection performance of flexible fabrics. The overall structure still maintains the design of Hitachi. Each group of annular flexible fabrics has independent driving and cleaning Ash device, only suitable for large dust collection device
