Insulation-box air-curtain shielding electrical dust remover

Abstract

The invention relates to an insulation-box air-curtain shielding electrical dust remover, which comprises a support-insulator insulation box and a rotating-shaft insulation box which are supported on an electrical dust removal box, wherein a first wind pipe is arranged in the support-insulator insulation box and is communicated with the inner cavity of the electrical dust removal box through the inner cavity of a tapered insulating sleeve; and a second wind pipe is arranged on the rotating-shaft insulation box and is communicated with the inner cavity of the electrical dust removal box through the inner cavity of the rotating-shaft insulation box. Hot wind is blown to the connecting position with the electrical dust removal box by adopting the wind pipes to form an air curtain, so that process gas can not invade into an insulator chamber, and the surface of an insulator can not be polluted. The condition that the insulator is polluted to be damaged can be eliminated fundamentally, the occupied ratio of air curtain wind mixed in the process gas is smallest, the normal operation of the system is not influenced, the balance of gas pressure of the production system can not be damaged, and the stable production can be always protected.

Description

technical field [0001] The invention relates to an electric precipitator, in particular to an insulating box air curtain shielding 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 n...

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
