As the automotive industry continues to grow, the production of discarded tires increases in proportion. Consequently, it is reasonable to assume that waste tire pollution is worsening every day. Consequently, people worldwide have developed various methods for disposing of discarded tires to limit and prevent pollution.
What Are the Different Methods for Disposing of Used Tires?
Currently, the most common methods for disposing of waste tires include waste tire recycling to recover rubber, tire retreading, and pyrolysis technology. Of these, pyrolysis technology is one of the most promising. This is due to the vast number of waste tires that pollute the environment.
What Is a Tire Pyrolysis Plant?
A tire oil plant is equipment that transforms discarded tires, as well as plastics and other solid waste, into oil, carbon black, and uncondensed gas. Using discarded tires as raw material in a tire pyrolysis plant helps recycle waste, thereby aiding in environmental conservation. In business, by selling the by-products of this process, investors can generate substantial profits.
The Workflow Steps of a Tire Pyrolysis Plant
Step 1: Feeding the raw materials
Automatic feeding equipment introduces waste tires or plastics into a pyrolysis reactor. The reactor should be loaded to a third of its volume to allow for smoother rotation. Ensure the inlet of the feeding machine is securely closed.
Step 2: Heating
The fuel material (LPG, tire oil, wood, natural gas, or coal, produced from waste tire/plastic to fuel oil pyrolysis plant) is gently heated in the pyrolysis reactor.
Step 3: Separation of the By-Products
When the temperature reaches 100°C (the top output rate interval is 250-280°C), the oil gas is emitted. The heavy oil gas separated from the manifold should liquefy and collect in the heavy oil tank. The lighter gas will rise to the oil condensers, where it condenses and is stored as oil. Lastly, the non-condensable gas is desulfurized and dedusted before being fed into the furnace, which heats the pyrolysis reactor for recycling.
Step 4: Cooling
The reactor should be cooled after all the fuel oil has been produced. When the temperature drops below 40 degrees, carbon black will be automatically expelled.
Step 5: Steel Wool Removal
If the source materials are discarded tires, steel wires are removed from the reactor using hooks once the temperature has dropped below 50 degrees Celsius.
Step 6: Purification of Exhaust Gas
If there is any remaining exhaust gas, it can be purified using a smoke cleaning system to bring it to emission standards.
In Conclusion
You can recycle scrap tires into renewable energy using the tire pyrolysis process. The best part is that you can do all of this without polluting the environment in the process. To prevent air and water pollution, ensure your waste tire pyrolysis facility includes a smoke cleaning system, tail gas cleaning system, odor elimination system, and water circulation system.
