Continuous tyre pyrolysis plants are employed to process waste tyre into carbon black and fuel oil. These plants typically add a pretreatment system, a continuous pyrolysis system plus a continuous discharge and feeding system controlled by way of a PLC system. The key component of these plants will be the pyrolysis system.
Ever since the feeding along with the discharge technique is continuous, this kind of pyrolysis plant is able to work non-stop or 24 / 7 that helps to conserve energy and time. Simultaneously, the PLC control system translates into far fewer labor costs.
The raw materials utilized in a continuous tyre pyrolysis plant include various different waste tyres produced from commercial and industrial sectors. The most prevalent waste matter include motorcycle tyres, bicycle tyres, OTR tyres, inner tubes, rubber overshoes, rubber hoses, truck tyres, car tyres, and more.
To preserve ongoing feeding and discharging, the waste tyres have to be small in dimensions. So before the pyrolysis process can commence, the types of materials are first shredded into smaller and much more manageable pieces. Listed below are more information connected with this process:
- Collect Waste Tyres
Waste tyres can be bought in many shapes and sizes from large OTR tyres to smaller car tyres.
- Shred Tyres
A specialized shredder can be used to process the tyres into 3 to 5cm pieces. This technique is really a fully automatic shredder that connects straight to the feeder. This step does away with having to transfer the types of materials in to the reactor.
- Feeding
Through a sealed unique feed-system, the broken down tyres are then fed right into a pyrolysis reactor which achieves a sustainable feeding process.
- Heating And Continous Pyrolysis Process
The pyrolysis reactor is heated by gas, LPG, or fuel oil. Throughout these heating processes, the reactor rotates 360 degrees, so that the tyre waste is uniformly heated. Once the temperature reaches around 300℃, the tyres crack and break up into oil gas.
- Cooling
The oil gas then flows right into a 3-stage condensing system, where gas cools down. The liquid oil produced through this procedure is then collected and stored in an oil tank. The leftover non-condensable gas will be employed to heat the pyrolysis reactor or stored.
- Discharge
Carbon black is likewise manufactured in this process. This device is discharged through a slag-discharge system. This method is sealed, making it eco friendly.
- Pyrolysis Oil
The pyrolysis oil is either sold directly or reprocessed into gasoline and diesel via waste-oil distillation equipment. Pyrolysis oil is likewise useful being an industrial fuel material for burning.
- Carbon Black
Carbon black can also be sold directly or reprocessed into high-quality carbon by way of a carbon-black processing machine. Carbon black is likewise used to produce carbon bricks.
- Steel Wire
Steel wire extracted from the waste tyres are widely used to make iron or steel rods or reprocessed for other uses.
- Combustible Gas
The combustible gas produced with the pyrolysis process is recycled then used as fuel to handle on providing a method to obtain heat on the reactor.
