In the cracking process of the tire, fuel oil generated by reaction can be directly discharged out of a cracking reaction kettle in a gas state and enters a gas bag for condensation; 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. In the initial stage of slag discharge, when the layer of oil sludge film meets the hot carbon black, the oil sludge film can be evaporated in a narrow slag discharge valve to form oil fume, explosion can be caused under certain conditions, and the safety production of a factory is seriously influenced.
