Anti-pollution hanging device for cathode system of electrostatic precipitator

Abstract

The invention relates to the technical field of electrostatic precipitation, in particular to an anti-pollution hanging device for an electrostatic precipitator cathodic system. The technical scheme includes the anti-pollution hanging device for the electrostatic precipitator cathodic system comprises a hanging rod, an insulating guard, an porcelain insulator and a base; the insulating guard, theporcelain insulator and the base are arranged from top to bottom sequentially, the hanging rod penetrates the insulating guard, the porcelain insulator and the base sequentially, a conical groove is formed in the upper end of the base, a circular air-guide groove is formed in the bottom surface of the conical groove, the lower end face of the porcelain insulator covers the opening of the circularair-guide groove along the circumference partially, the base is provided with an air outlet running through the upper end and the lower end thereof and disposed on the inner side of the circular air-guide groove, the hanging rod penetrates the base through the air outlet, a circular air-guide plate is arranged on the lower end face of the insulating guard, and is used for guiding air of an air-guide passage to the outer wall of the porcelain insulator. According to the technical scheme, the device can prevent the porcelain insulator from pollution flashover.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitator, in particular to an antifouling hanging device for a cathode system of an electrostatic precipitator. Background technique [0002] Electrostatic precipitator is a high-efficiency dust removal equipment used to capture fine dust in gas. It uses electrostatic force to separate solid or liquid particles from airflow, thereby purifying dusty flue gas. When a high-voltage direct current is applied to form an electric field between the discharge electrode and the dust collection electrode arranged at intervals inside the electrostatic precipitator, a space sufficient to ionize the gas is maintained, and the gas around the discharge electrode will be ionized to form gas ions and electrons. When the dust-containing gas passes through the electric field, ions and electrons are attached to the surface of the dust particles to charge them during the movement. The purpose of separation f...
