[0002] Electric dust collectors are widely used in thermal power generation and industrial production, and are one of the mainstream technologies for treating particulate matter emissions. The basic principle is to ionize the dust-containing gas using a high-voltage electrostatic field, rapidly charge the smoke dust particles, and adsorb them on the opposite electrode under the action of the electric field force. The dust on the electrode is removed by shaking and other methods and falls into the ash hopper and is transported to the ash storage for storage.
[0003] With long-term operation of the equipment, the accumulation of particulate matter on the surface of the anode plate and cathode wire leads to dust wrapping and hardening, which not only reduces the dust removal effect, but also may cause equipment failure and even safety accidents. Therefore, it is necessary to take full advantage of the opportunity for shutdown maintenance for cleaning. However, the inside of the electric dust collector is hot and smoky, with insufficient light and inconvenient personnel movement, and the risk is high, so the maintenance quality cannot be guaranteed. Moreover, it is impossible to set up a lifting platform or scaffolding inside the electric dust collector, and the safety of personnel is entirely dependent on safety belts and anti-falling devices, which belongs to the category of high-risk and high-risk operations.
