After the waste tires are recycled, the waste tires are generally decomposed into fuel oil, carbon black and steel wires by oil refining equipment, so that the resources are recycled. In the cracking process of the tire, the fuel oil generated by the reaction can be directly discharged out of the cracking reaction kettle in a gas state and is condensed into liquid fuel oil through a condensing mechanism; after the cracking of the tire is finished, carbon black generated by the reaction can be discharged out of the cracking reaction kettle through a slag discharging system. However, after oil refining, a small amount of residual oil gas generally exists in the cracking reaction kettle, and the residual oil gas enters a slag discharge system when a slag discharge valve is opened and adheres to the inner wall of the slag discharge valve to form a layer of oil sludge film.
