Waste and old tire cracking device and cracking method thereof

Abstract

A cracking unit of waste tyres is provided, which comprises a cracking furnace, a heating mechanism and a collecting mechanism of cracking materials. The unit is characterized in that: the cracking furnace comprises a combustion chamber on the bottom and a high temperature cracking room over the combustion chamber and the combustion chamber and the high temperature cracking room are separated by a division board between the two; the heating mechanism is positioned in the combustion chamber; the collecting mechanism of cracking materials comprises a solid collector for collecting solid products and a condenser for collecting gaseous products, wherein, the air inlet of the condenser is connected with the high temperature cracking room through an air shooter and the product outlet of the condenser comprises a gas phase outlet for outputting unset gas and a liquid phase outlet for outputting condensate, and the gas phase outlet is connected with the heating mechanism; the front end of the high temperature cracking room is connected with a feeding conveyor mechanism. A moving bed pyrolysis boiler has simple structure and compact dimension and is used for processing the waste tyres with simple decomposition and processing technology process and short processing period, and can adjust and control the yield of the products through changing the decomposition temperature and controlling the detention time of the tyres in the pyrolysis chamber. In addition, the system can independently operate relying on itself without additionally supplying burning fuels and making best use of all materials.

Description

technical field [0001] The invention relates to a cracking and recycling device for waste tires and a cracking method thereof, in particular to a cracking device and a cracking method for waste tires which can crack the whole tire and operate independently without additional energy consumption. Background technique [0002] With the rapid development of the automobile industry, the number of waste tires is also increasing day by day, causing serious pollution to the environment. To this end, countries have invested a lot of manpower and material resources in researching the recycling and utilization of waste tires. At present, the most ideal treatment method for these wastes at home and abroad is to use pyrolysis method, that is, put the waste tires into the pyrolysis furnace for pyrolysis, and recover useful substances from the pyrolysis products for reuse. This method not only eliminates environmental pollution, but also enables comprehensive utilization of waste, turning...

AI Technical Summary

Problems solved by technology

The waste tire pyrolysis device is evenly heated; the coarse carbon black and scrap steel wire after tire feeding and pyrolysis can slide out of the kettle along the slope under the action of its own gravity, which saves the conveying device of the material in the kettle; but the pyrolysis cycle is relatively short. long, low production efficiency
