Waste Tyre Pyrolysis Plant
- Capacity: 10-20 t/d
- Equipment: condenser system, gas cooler, gas treatment, etc.
A waste tyre pyrolysis plant is a technology plant that breaks down used tyres into kinds of usable resources. Waste tyre pyrolysis plants adapt pyrolysis method to turn waste tyres into fuel oil, carbon black, steel wire and combustible gas. This process not only cracks waste tyres, but also generates useful oils and chemicals of great economic value.
Pyrolysis Process Of Waste Tires
- STEP 1: Raw material crushing: Tire crushing system remove steel wire, and crush waste tyre into particle size less than or equal to15mm colloidal particles.
- STEP 2: Preheat dehydration: The material enters the flue gas preheat dehydration dryer, evaporative moisture as much as possible, and enters the reaction still. The material mixes with the reactor’s energy ball that is put into the reactor in advance of the process.
- STEP 3: Deep dehydration and primary distillation: The material gradually heats up in the reactor, and dehydration and preliminary pyrolysis at around 150-350 ℃. Water and light component oil enter the heat transfer system in the initial distillation section cooling condensation. The liquid enters the tank for another use. The dry gas is purified and is used in the heating furnace for burning and pyrolysis.
- STEP 4: High temperature pyrolysis: The material enter high temperature pyrolysis process, fully heated and distillate gaseous substances such as oil under 500-700℃. The oil and dust are sent to separator of heat exchange system in high temperature section. Dust and reconstituted oil separator is initially condensed and separated by heat transfer, the liquid enter the tank for another use.
- STEP 5: Separation of slag and energy ball: The energy ball run in bottom in the role of the guide groove and separated by the separation net.the energy ball continue to circulate in the reactor, and the slag material falls into the slag extractor.
- STEP 6: Slagging: The material enter one stage slag extractor to discharge. Then enter two stage slag extractor to reduce temperature. Finally enter three stage dust removal, heat exchange slag extractor to discharge to temporary storage.
- STEP 7: Dry gas purification: The dry gas enter dry gas purification treatment system, then is sent to the heating furnace through the dry gas burner, finally heat reactor.
- STEP 8: Flue gas heat transfer and purification: The furnace heat and dehydrate the raw material in a waste heat utilization device. Then enter the flue gas treatment system. Finally enter denitrification desulfurizer to let out.
Waste Tire Pyrolysis Treatment Equipment
Preparation system
Tire cut into little particle through wire tire shredder and tire shredder. Then it further broken into smaller particles through cutter or hammer.
Condenser system
It is composed including irculation water tank, pipeline, control valve and condenser, condensing tower. Condenser adapt combination of four horizontal and four vertical tubular condenser arrays, ensure achieve gas and liquid separate.
Pyrolysis system
The reactor is composed of one stage dehydrating initial distillation reactor, two stage high-temperature pyrolysis carbonization reactor, an energy ball circulation device and an outlet gas sealing device.
Flue gas treatment system
Combustion and pyrolysis in the combustion chamber should be gradually removed by the water scrubber. After desulfurization, and activated carbon adsorption treatment. It is discharged through the exhaust pipe. At the same time, dust producing sections such as crushing, feeding, carbon black packaging dedust post-treatment discharge.

Waste Tyre Pyrolysis Plant Prospect
Waste tyre pyrolysis is a sustainable environmental industry. It not only reduces pollution that is caused by waste tyres, but also turns waste tyres into useful oils and chemicals, then puts them back on the market. In addition, the cost of waste tyre pyrolysis is increasingly reduced. For example, pyrolysis equipment could be miniaturized. It reduces depreciation costs and transportation costs. These elements together promote the development of waste tyre pyrolysis plant.
