Tyre or plastic pyrolysis refers to an irreversible thermochemical reaction that uses high temperature to decompose organic compounds in waste tyre or plastic under the condition of no oxygen or lack of oxygen to escape volatile products and travel solid coke. If there is too much oxygen in the cracking process, the waste tyre or plastic will react with oxygen during the cracking process to become carbon dioxide and water. Therefore, the pyrolysis of waste tyre or plastic must be performed under anaerobic or anoxic conditions.The equation for absence of oxygen cracking of waste tires or plastics is as follows:
(-CH2-CH2-)n→n[C+H2+CH4+C2H6+C3H8+C4H10+C5H12+...+C11H24+C20+H42+...]
The principle of pyrolysis technology is the process of cracking long chain molecules of organic matter in waste tyres or plastics into short chain molecules in the absence of oxygen. If the waste tyres or plastic is heated in the presence of oxygen, the process is not pyrolysis, but burned.
Principle of pyrolysis technology
The composition of waste tyres or plastics after combustion is very complicated. In addition to a large amount of carbon dioxide, sulfur dioxide, carbon black (dense smoke caused by incomplete combustion) nitrogen oxides, and some toxic organic substances such as dioxins, it is very polluting to the environment.
The pyrolysis of waste tyres or plastics is performed by heating outside the thermal pyrolysis reactor and anaerobic thermal pyrolysis. The sealed reactor body containing waste tyres or plastics ensures that no gas is leaked during the production process, which fundamentally eliminates the safety hazards and secondary pollution problems caused by gas leakage during the production process.
The sealed reactor body of waste tyre/plastic pyrolysis plant
Waste tyre pyrolysis plant is a professional equipment for the anaerobic pyrolysis of waste tyres or plastics. The equipment adopts a rotary furnace design, which increases the heat transfer area during the pyrolysis process, rotates slowly, and evenly heats, improving the pyrolysis efficiency. Pyrolysis plant is a machine that takes waste tyre and plastic through pyrolysis process to obtain fuel oil and carbon black as main products.
The main product of waste tyre pyrolysis plant
Waste tyre pyrolysis plant not only effectively handles the accumulation and pollution of waste thres and waste plastics, but also obtains fuel that can be reused by the market during the process.
This device serves two purposes and is the perfect choice for recycling waste tyres and waste plastic.
