Cathode component of electrostatic dust collection device

Abstract

The invention provides a cathode component of an electrostatic dust collection device, relates to the field of electrostatic dust collection, and specifically relates to a cathode component of an electrostatic dust collection device. The cathode component comprises a cathode main body and a discharge component, wherein the cathode main body comprises more than two cathode cylinder single bodies which are arranged along the axis direction; and the adjacent cathode cylinder single bodies are detachably connected together. According to the invention, through the design that the cathode componentcomprises more than two cathode cylinder single bodies and the adjacent cathode cylinder single bodies are detachably connected, the traditional manual welding is replaced by the connecting mode of connecting the adjacent cathode cylinder single bodies through threads, so that the consistency of the connecting quality is ensured, the cathode cylinder single bodies are convenient to assemble and process, and the production and installation efficiency is effectively improved; and the number of the cathode cylinder single bodies can be increased through threaded connection according to the dust collection requirement, so that the height of the cathode component is increased, the dust collection effect is improved, and the installation is safe.

Description

technical field [0001] The invention relates to the field of electrostatic dust removal, in particular to a cathode part of an electrostatic dust removal device. Background technique [0002] Electrostatic dust removal is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through a high-voltage electrostatic field. After the dust particles and negative ions are combined with negative charges, they tend to discharge and deposit on the surface of the anode; they are used to purify gases in metallurgical, chemical and other industries. Or recover useful dust particles. 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. In the strong electric field, the air molecules are ionized into positive ions and electrons, and the electrons encounter dust particles in the process of rushing to the positive electrode, so that the dust particles are...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing electrostatic precipitators usually use cylinders with upper and lower openings as the cathode structure, and the cathode cylinders are usually connected by manual welding during assembly. Manual welding is inefficient and cannot guarantee consistent welding quality and when encountering higher dust removal requirements, the dust removal requirements can only be met by increasing the height of the electrostatic precipitator area (cathode and anode area), that is, only on the basis of the cathode cylinder and welding another Cathode cylinder, this process often needs to work at high altitude, the welding quality cannot be guaranteed, and the high-altitude operation is very dangerous, threatening the safety of construction personnel;

[0005] 2. When the cathode part of the electrostatic precipitator is damaged, it is necessary to replace and repair the damaged part of the cathode part. However, because the existing electrostatic precipitator is assembled in a way where the cathode and the anode are nested, maintenance is troublesome. high cost;

[0006] 3. The existing electrostatic precipitator uses burrs on the cathode part as the discharge tip. The processing method is rough, and the positions of the burrs on the cathode part are random and inconsistent, which cannot guarantee the formation of a three-dimensional power grid, resulting in the electrostatic dust removal of the device.
