Background
The electric dust collector is widely used for various waste gas treatment, removes particulate matters in waste gas by electric field force, and is the most effective particulate matter trapping and gas purifying device. Traditional electrostatic precipitator contains discharge electrode and collection dirt utmost point, and the collection dirt utmost point of the board-like structure of wide use is used for collecting the particulate matter. Along with the continuous progress of the collection process, on the one hand, a large amount of particles (including solid particles, oil drops, aerosol and the like) cannot automatically drop by means of gravity, and along with the positive attachment of the particles, the electric field characteristics such as discharge intervals and the like are greatly influenced, and the dust collection efficiency is greatly reduced. And also affects the life of the dust collecting electrode. Cleaning of the collecting electrode, such as vibration, high pressure water spraying, high pressure steam spraying, etc., is required periodically or aperiodically, and even manual cleaning, the cleaning process affects the electric field, so that the collecting process needs to be stopped intermittently. The production process is seriously influenced; on the other hand, the dust collector is not easy to cool or heat, if the dust collector needs to be cooled or heated, a heat exchange device needs to be added, and the system is complex and large. Therefore, the traditional dust collecting electrode material cannot simultaneously and effectively collect dust and convey collected particles, cannot input cleaning substances such as cleaning agents and the like, cannot convey energy (such as cooling or heating) and cannot intermittently and efficiently and continuously operate due to the fact that an electric dust collector manufactured by the traditional dust collecting electrode needs to be intermittently cleaned and the like.
