Technical Field

[0001] The utility model belongs to the technical field of industrial oil fume purification, and specifically relates to a cleaning device for an electrostatic tar precipitator. Background Technique

[0002] An electrostatic tar precipitator refers to a primary cooler for coke oven gas that separates tar droplets and gas by using the action of a high-voltage direct current electric field. After a general electrostatic tar precipitator is used for a period of time, it needs to be cleaned. However, the cleaning device of the general electrostatic tar precipitator cleans through a spraying device, and the spraying device is usually arranged at the upper part of the electrostatic tar precipitator. After a long time, a large amount of oil stains will adhere to the spraying device and block the spraying ports. For this reason, we propose a cleaning device for an electrostatic tar precipitator.
