[0002] In the process of metal smelting, smoke containing more oil, grease, sulfide and alkaline substances will appear. The commonly used methods include: spraying + adsorption, spraying + demisting + sintering plate dust removal, bag + spraying, etc. However, since smoke is easy to stick together, the above treatment methods will result in poor treatment effect, or the treatment equipment is easy to be blocked, and the equipment service life is short.

[0003] Electrostatic adsorption dust removal is a dust removal method that uses a high-voltage direct current electric field to act on charged particles, causing the particles to move toward the electrode and attach to the collection plate, thereby removing dust particles from the airflow. It has the characteristics of high dust removal efficiency, low energy consumption, and suitability for high temperature and high pressure. It is widely used in air pollution control in the power, chemical, steel, cement and other industries, and is an ideal method for controlling atmospheric dust pollution. In order to prevent the cathode wire from shaking back and forth under the blowing force of the flue gas, the existing equipment with electrostatic adsorption dust removal function usually uses a fixing device to stretch the two ends of the cathode wire to make the cathode wire tense.
