Quality appraisal of radial flow electrostatic precipitator

radial electrostatic precipitator is a radial industrial electrostatic precipitator technology that adopts a rotating transverse electrode electric field structure and the moving anode plate is made of nickel-based foam metal material.
is different from the structure of the wet electrostatic precipitator. Its structural arrangement is that the anode plate of the dust collector is perpendicular to the direction of the air flow, so that the direction of the electric field force and the induced wind are on the same horizontal line. Under the joint action of the wind field and the electric field force, the dust particles are clamped on the new anode plate. The device is mainly composed of a shell, a distributor, an anode device, a cathode device, a spray system, a hot air system and a power supply.
In the quality case of radial flow electrostatic precipitator, quality appraisal is an essential link. Zhongke Testing provides quality appraisal services for run-off electrostatic precipitators.

1, radial flow electrostatic precipitator (body, power supply) quality
2, on-site installation quality
3, user's operation and maintenance level

was entrusted by a court to analyze the cause of the failure of the "run-off electrostatic precipitator" in which the dust removal efficiency decreased. The expert group discussed the relevant information and on-site investigation and inspection of the "run-off electrostatic precipitator" involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
1. The "run-off electrostatic precipitator" involved was inspected and studied. Finally, it was believed that the quality of the "run-off electrostatic precipitator" involved was not problematic, and all indicators were in compliance with national standards.
2. After verifying the design with other solutions, it was found that the user's untimely operation and maintenance caused the dust removal efficiency to decrease. It is recommended that after each shutdown of the furnace, check the dust accumulation on the pole plates, pole lines, and distribution plates. If the thickness of the dust accumulation is 1-3 mm, it is normal. If the dust accumulation exceeds 5 mm, manual cleaning is required (compressed air cleaning or water flushing can be used). At the same time, find out the cause and eliminate the fault. If the rapping is normal but the dust accumulation is thick, the rapping time needs to be extended or the rapping cycle shortened.
