Insulation shaft insulation box of electrostatic precipitator

Abstract

The present invention discloses an insulation shaft insulation box of an electrostatic precipitator. According to the present invention, the insulation shaft insulation box is connected with an electrostatic precipitating box; a rotation shaft insulator is arranged inside the insulation shaft insulation box; one end of the rotation shaft insulator is connected with a motor drive shaft, the other end of the rotation shaft insulator is connected with a vibration and beating shaft; the insulation shaft insulation box further comprises an air duct arranged on the insulation shaft insulation box; the air duct is communicated with an inner chamber of the electrostatic precipitating box by the insulation shaft insulation box. With the present invention, hot air is blown to the low end surface of the contacting position of a conical insulation casing and the electrostatic precipitating box by the air duct to form an air curtain, and is blown to the surrounding of the vibration and beating shaft to form an air curtain, the air curtains and a quartz plate for supporting the vibration and beating shaft collectively provide a shielding effect; the pressure of the air curtain is slightly higher than the pressure of the process gas, such that the process gas can not invade the support insulator insulation box and the insulation shaft insulation box, the surface of the insulator can not be contaminated, the normal operation of the system is not affected, the balance of the gas pressure of the production system is not damaged so as to always protect the smooth production.

Description

technical field [0001] The invention relates to an electric precipitator, in particular to an insulating shaft insulation box of the electric precipitator. Background technique [0002] The electrostatic precipitator is a device that uses a high-voltage electric field to separate dust that is highly suspended in the gas. The electrode that sends high voltage is the cathode, and the electrode that collects dust is grounded. The dust adsorbed on the electrode is shaken off by vibration and discharged from the ash hopper. There are three faults of electrostatic precipitator recognized by dust collectors at home and abroad. One is that the cathode line breaks and falls off, causing the cathode and anode to be connected and cannot be powered on; The cathode support insulator is polluted, and the insulation fails to transmit high voltage. Replacing thin metal wires with rigid cathode wires can make the cathode uninterrupted, and replacing the split hammer with a whole hammer can...

AI Technical Summary

Problems solved by technology

When the electrostatic precipitator is running, the surface of the insulator is in contact with the process gas. If water vapor, acid, etc. in the process gas condense and adhere to the insulator, the surface insulation will fail, resulting in surface leakage. The insulator is burned out and cracked or broken. Some particles in the process gas adhere to the surface of the insulator and cause insulation damage. The traditional treatment method is manual cleaning or blowing cleaning, which fails to solve the problem fundamentally
