High-voltage electrostatic dust collector cathode plate

Abstract

The invention provides a high-voltage electrostatic dust collector cathode plate which is arranged in a dust removal chamber through a connecting part and connected with a cathode of a constant-current high-voltage power source. The cathode plate is composed of multiple modules sequentially arranged between a large left framework and a large right framework from top to bottom. The modules are installed on the large left framework and the large right framework in a hung manner through flexible vibration reducing and damping structures. An independent high-frequency vibrator is arranged on eachmodule. Each module is of a latticed structure composed of a small framework and a cathode bar on which cathode pins are distributed uniformly. Lattices in each module are connected in a non-closed manner. The cathode plate is novel in design, when the vibrators are started or stopped, resonance energy is little, after the vibrators are started, long-time stable resonance-free high-frequency vibration can be generated, dust can be removed efficiently, the discharging ability can be ensured effectively, the service life is long, and the electrostatic dust collector cathode plate has outstandingpracticality and remarkable economic value.

Description

technical field [0001] The invention relates to a cathode plate of a high-voltage electrostatic precipitator, in particular to a cathode plate suitable for high-frequency vibration dust removal, and belongs to the technical field of flue gas purification. Background technique [0002] With the intensification of air pollution and the rapid development of social economy, the country has introduced more stringent air pollution prevention and control laws, and set higher standards for smoke emissions. As a simple and efficient dust removal method, electrostatic precipitator technology is widely used in the field of flue gas purification. However, the lack of cathode plate ash removal technology in existing electrostatic precipitators has seriously affected the long-term efficient and stable operation of electrostatic precipitators, and ultimately affected To the continued application of electrostatic precipitator technology under the new emission standards.

AI Technical Summary

Problems solved by technology

However, because high-frequency vibration can easily lead to fatigue damage of stress-concentrated parts of structural parts, greatly reducing the service life of components, therefore, it is difficult to apply high-frequency vibration to the dust cleaning operation of existing electrostatic precipitators

In addition, if the vibration damping and isolation effect of high-frequency vibration is not good, especially the resonance elimination in the start and stop stages is not good, the vibration will be directly transmitted to other non-vibrating parts of the dust collector, and the overall structure of the dust collector will be damaged.
