DOING® Waste Tyre to Pyrolysis Oil Recycling Plant

Waste tire pyrolysis oil recycling plant

1.What is Tire Pyrolysis Technology?

Pyro = heat. Lysis = break down.

Pyrolysis is chemical reaction. This reaction involves molecular breakdown of larger organic molecules into smaller molecules in presence of heat. Pyrolysis is also known as thermal cracking, cracking, thermolysis, depolymerization, etc. It differs from combustion (oxidation) and effectively avoids the generation of harmful substances.

Tire pyrolysis specifically involves placing waste tires in a closed, anaerobic or low-oxygen reactor and subjecting them to a pyrolysis reaction at a high temperature of approximately 400 to 450 degree Celsius. During this tire pyrolysis process, the organic polymers (rubber) in the waste tires decompose into gaseous, liquid, and solid products. This is a green and environmentally friendly process that converts waste into industrial fuels like TPO/TDF (tire pyrolysis oil/tire derived fuel), carbon black, steel wire, and combustible gas(hydrocarbon gas).

Pyrolysis is a great and sustainable way of recycling large amounts of tires, which can not only work as a solution for tyre treatment&management, but also produce alternative fuel for profits.

2. DOING® Waste Tire to Pyrolysis Oil Recycling Plant

DOING® waste tire to pyrolysis oil recycling plant is a high-tech device specifically designed for the efficient processing of waste tires. It effectively decomposes the complex long-chain polymers (containing over 50,000 carbon atoms, linked in cross-linked or straight-chain form) in waste tires into shorter chains, converting them into fuels and materials with high utilization value.

2.1 Core Advantages of the Tire to Pyrolysis Oil Recycling Equipment

High Oil Yield: Optimized pyrolysis reactor design ensures a high conversion rate of waste tires and excellent oil quality.

Safe and Reliable: Strictly adhering to national and industry safety standards, equipped with a complete safety interlock system, over-temperature and over-pressure alarms, and pressure relief devices to ensure safe and stable equipment operation.

Environmentally Compliant: Waste gas, wastewater, and waste residue are all properly treated. The exhaust gas undergoes multi-stage purification to meet emission standards or can be recycled; wastewater is recycled; and slag (carbon black) is treated harmlessly or further processed.

Environmental devices of tire pyrolysis oil production plant

Energy-efficient and high-performance: Utilizing advanced heat exchange systems and combustible gas recovery technology, energy consumption is significantly reduced, optimizing operating costs.

High degree of automation: Automated feeding and discharging systems and PLC control systems can be configured according to customer needs, reducing labor costs and improving production efficiency.

Strong adaptability: It can process not only waste tires but also various organic wastes such as waste plastics, waste oil sludge, and waste rubber through pyrolysis.

2.2 Tire to Pyrolysis Oil Recycling Process Working Principle Overview

①Pretreatment: Waste tires undergo pretreatment processes such as crushing and fiberization, or are fed whole (depending on the equipment model).

②Closed feeding: The treated waste tires are fed into the pyrolysis reactor via an automated or manual system.

③Heating and pyrolysis: In an oxygen-free environment, the reactor is externally heated, causing the tires to undergo a pyrolysis reaction at a preset temperature (400-450°C).

④Condensation and Separation: The oil-gas mixture produced by pyrolysis enters the cooling system, where it undergoes multi-stage condensation to separate the pyrolysis oil.

⑤Exhuast Gas Treatment: The uncondensed combustible gas (syngas) is purified. Part of it is returned to the combustion chamber as fuel to heat the tyre pyrolysis reactor, saving fuel investment for the operation of tyre pyrolysis oil production plant.

⑥Carbon Black and Steel Wire Discharge: After pyrolysis, the carbon black and steel wire in the reactor are discharged under sealed conditions, cooled, and then processed further.
