Continuous tyre pyrolysis plants are widely used to process waste tyre into carbon black and fuel oil. These plants typically incorporate a pretreatment system, a continuous pyrolysis system plus a continuous discharge and feeding system controlled from a PLC system. The key part of these plants will be the pyrolysis system.
Since the feeding and also the discharge technique is continuous, this kind of pyrolysis plant will be able to work non-stop or around the clock which assists to save time and energy. As well, the PLC control system results in far fewer labor costs.
Raw Materials
The raw materials employed in a continuous waste tyre pyrolysis plant (máquina para pirólisis de plásticos) include a number of different waste tyres produced by commercial and industrial sectors. The most frequent waste matter include motorcycle tyres, bicycle tyres, OTR tyres, inner tubes, rubber overshoes, rubber hoses, truck tyres, car tyres, and a lot more.
Working Process
To preserve ongoing feeding and discharging, the waste tyres have to be small in dimensions. So before the pyrolysis process can commence, the type of material are first shredded into smaller and much more manageable pieces. Listed below are more info related to this method:
- Collect Waste Tyres
Waste tyres are available in many sizes and shapes from large OTR tyres to smaller car tyres.
- Shred Tyres
A specialized shredder is utilized to process the tyres into 3 to 5cm pieces. This product is actually a fully automatic shredder that connects right to the feeder. This task does away with having to transfer the type of material to the reactor.
- Feeding
Via a sealed unique feed-system, the separated 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. Through these heating processes, the reactor rotates 360 degrees, to be sure the tyre waste is uniformly heated. After the temperature reaches around 300℃, the tyres crack and breakdown into oil gas.
- Cooling
The oil gas then flows right into a 3-stage condensing system, the location where the gas cools down. The liquid oil produced through this procedure will be collected and held in an oil tank. The leftover non-condensable gas is then used to heat the pyrolysis reactor (proceso de tratamiento de lodos de petroleo crudo) or stored.
- Discharge
Carbon black is also produced in this method. This device is discharged using a slag-discharge system. This product is sealed, so that it is environmentally friendly.
Final Products From The Continuous Tyre Pyrolysis Plant
- 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 as an industrial fuel material for burning.
- Carbon Black
Carbon black can also be sold directly or reprocessed into high-quality carbon using a carbon-black processing machine. Carbon black is also used to produce carbon bricks.
- Steel Wire
Steel wire extracted from the waste tyres are used to make iron or steel rods or reprocessed for other uses.
- Combustible Gas
The combustible gas produced from the pyrolysis process is recycled then used as fuel to hold on providing a supply of heat on the reactor.
