An electric tar catcher refers to a coke oven gas primary cooling equipment that uses the action of a high-voltage direct current electric field to separate tar droplets and coal gas. The electric tar catcher can be installed before or after the coke oven gas blower. Compared with mechanical tar removers, electric tar catchers have the characteristics of tar capture, low resistance loss, and large gas processing capacity. Not only can it meet the requirements for gas quality in subsequent processes and improve product recovery rates, but it can also significantly improve the operating environment.

The electric tar catcher adopts three structural forms: concentric circle, tube, and honeycomb. Regardless of the structure, its working principle is to apply high-voltage direct current between the metal wire and the metal tube wall [or electrode plate] to maintain an electric field sufficient to ionize the gas, forming a corona zone between the anode and cathode.

effect:

The tar capture efficiency is high, and the tar mist content in the exported gas can be reduced to below 50mg/m3. During production operation, the temperature of the surrounding space of the insulator in contact with gas should be kept stable, and the insulator should be wiped regularly. The dirt on its surface. If the surrounding space of the insulator is sealed with nitrogen gas, it can extend the operating cycle of the equipment.
