Abstract
The invention discloses a carbonization cracking system for waste plastics. The system utilizes a molten salt furnace to provide heating heat for a cracking furnace, so that a material in the crackingfurnace is continuously cracked, and a combustible gas generated by cracking of the material is used as a fuel of the molten salt furnace to maintain continuous heating of the molten salt by the molten salt furnace; the molten salt circularly flows in the cracking furnace and the molten salt furnace, so that a cracking chamber is heated continuously; and because a specific heat capacity of the molten salt is larger, the molten salt has a temperature of about 500 DEG C when flowing out from the molten salt furnace, and the molten salt has a temperature of about 480 DEG C when flowing back to the molten salt furnace, a cracking temperature difference is only about 20 DEG C, so that the entire carbonization cracking process is performed in a very stable temperature range. According to the system provided by the invention, in the above way, firstly, the material can be fully cracked; and secondly, the combustible gas generated by cracking is directly utilized, so that the molten salt furnace does not need to consume an external combustible gas, energy consumption of the carbonization cracking system is reduced, and a utilization rate of the material is improved.
