Embodiment Construction

[0028] see Figure 1-Figure 7 200 kg of whole waste tires that do not need to be crushed or cut and only cleaned and descaled are sent to the feed port 10 through the conveyor belt 32, the discharge furnace door 36 is closed, the feed furnace door 17 is opened, and the waste tires are put into the waste tires in sequence. In the liner 3, since the kettle body and the ground maintain a 30-50° inclination angle 9, the waste tires will slide down freely in the liner 3 relying on gravity, and continuous feeding can make the waste tires arranged in the inner tube 3 until Full of, close charging furnace door 17. Open hot-blast stove 31, provide the hot air flow that temperature is 600-800 ℃, enter heating layer 5 from the hot air inlet 4 of cracking kettle 1 and circulate and heat liner 3, be provided with shunt channel 15 in heating layer 5, heat layer The inner tank 5 is divided into multiple passages to increase the heat transfer rate so that the temperature of the inner tank 3 ...

Abstract

This invention discloses a technique for pyrolyzing whole waste tires in a specially designed inclined rectangular pyrolysis kettle. The technique comprises: (1) putting whole waste tires into the pyrolysis kettle, and pyrolyzing at 350-450 deg.C and 100-300 mmH2O for 30-60min; (2) cooling and separating the discharged pyrolysis gases to obtain mixed fuel oils and flammable gases; (3) recovering the residual solid materials discharged from the bottom of the pyrolysis kettle to obtain carbon black and steel wires. The technique has such advantages as simple equipment, shortened process flow, low coat and no secondary pollution.

Description

technical field [0001] The invention relates to a process for cracking and recovering fuel oil, combustible gas, carbon black and steel wire from waste tires. Background technique [0002] With the rapid development of the automobile industry, the amount of waste tires is also increasing day by day, causing serious pollution to the environment. At present, the most ideal method of environmental protection treatment of these wastes at home and abroad is to use high-temperature pyrolysis, that is, to put the waste tire blocks into a certain cracking furnace for dry distillation and cracking, and recover fuel oil, combustible gas and carbon black therefrom. This method not only eliminates environmental pollution, but also enables comprehensive utilization of waste, turning waste into wealth, and generating considerable economic benefits. Designing a suitable pyrolysis equipment is the key to success in the realization of the pyrolysis process. The rationality and applicability...
