Tire recycle machine pyrolysis

Types of tire recycle machine pyrolysis

The tire recycle machine pyrolysis processes used tires using high-temperature conditions in the absence of oxygen. Several designs exist to carry out this reaction, and they can be categorized by their heating method or their degree of integration.

• By heating method

Indirect heating machines use another unit to generate heat that will then be transferred to the reactor. This is often done using thermal oil. The unit responsible for the heat generation will be outside of the reactor. For instance, the oil could be heated by a natural gas burner. When using indirect heating, the reactors can be smaller and easier to handle.

Direct heating pyrolysis machines have the heat source directly in contact with the reactor. Sometimes, the reactor will be rotated to evenly distribute the heat and ensure uniform processing of the feedstock. Directly heated reactors have a higher thermal efficiency.

• By degree of integration

Integrated units combine shredding and pyrolysis into one machine. Usually, it is a continuous feeding system that includes a shredder before the pyrolysis chamber. The waste material is then fed into the reactor belt. These types of machines are more energy efficient.

Separating units are standalone shredders that process the material before it goes into the pyrolysis chamber. Many shredder units are now designed to integrate smoothly with the feed mechanism of existing pyrolysis reactors.

Specifications and maintenance of tire recycle machine pyrolysis

Specifications

• Capacity:

  The capacity of a tire pyrolysis machine is typically expressed in tons per day (TPD) or batches per day. Common capacities range from 5-15 TPD, meaning the machine can process 5 to 15 tons of tires in a 24-hour period.

• Feeding method:

  Automatic feeding systems use mechanisms like conveyor belts or augers to continuously supply shredded tires into the reactor. Semi-automatic systems require operators to periodically batch and feed the tires into the reactor. Manual feeding is suitable for smaller capacity machines that cannot process large volumes at once.

• Heating method:

  The three common heating methods for tire recycling machines are electric heating, coal or wood firing, and natural gas or other combustible gas. Electric heating uses built-in electric heaters to raise the temperature of the reactor. Coal or wood firing requires burning solid fuels in an external furnace to heat the pyrolysis reactor. Natural gas heating uses a flame directly inside a burner situated below the pyrolysis reactor to provide indirect heating.

• Oil output:

  The type and amount of oil produced depend on factors such as the machine's configuration, operating conditions, and the composition of the recycled tires. Generally, tire pyrolysis machines can yield around 30% to 50% of the processed tires' weight as pyrolysis oil.

• Condensing system:

  The Condensing system in a tire recycling machine collects and cools down the vapor released during the pyrolysis process. This system is typically equipped with condensers and cooling units to effectively cool the vapor and convert it into liquid oil.

• Gas treatment system:

  The gas treatment system is responsible for handling the gaseous byproducts generated during pyrolysis. It typically includes filters, scrubbers, and other cleaning devices to remove harmful components and ensure the safe emission of gases.

Maintenance Tips

Regular maintenance and timely repair of the waste tire recycling machine Can not only ensure product quality but also extend its service life. Here are some maintenance tips for waste tire recycling machines for buyers:

• Check the fasteners regularly: Check the fasteners on the recycling machine, such as screws, bolts, etc., to ensure they are in the proper state. If they are loose, which requires fastening, this can prevent equipment failure or safety hazards caused by loosening.
• Lubrication maintenance: Pay attention to the lubrication of movable parts of the recycling machine. Lubricating oil can reduce friction and abrasion between parts, so keep them clean and add the appropriate lubricating oil.
• Keep the machine clean: Regularly clean up the waste material and dust on the recycling machine to prevent blockage and overheating. Dust is easily flammable, so cleaning also helps to improve safety.
• Check electrical lines: Periodically check the electrical lines and connectors of the recycling machine and ensure that they are not worn or loose, which helps to maintain stable equipment operation.
• Cooling system maintenance: The waste tire recycling machine's cooling system is vital for dissipating heat. Regularly clean the radiators and cooling fans to avoid overheating parts.
• Pay attention to operating parameters: During operation, pay attention to the machine's operating parameters (e.g., temperature, pressure, etc.) to ensure that they are within the prescribed limits and promptly deal with abnormalities.

How to choose tire recycle machine pyrolysis

Choosing the right tire recycling machine involves more than just picking a model. It is about understanding the entire system and supply chain. Here are some key factors to keep in mind when selecting a tire recycling machine.

• Capacity: When investing in a tire recycling machine for business purposes, it is essential to consider the machine's capacity. Will it meet the project's needs? An industrial-scale machine with a high capacity is typically large and costly. Ensure that personnel, facilities, and budget can all accommodate the new investment.
• Quality of end products: Evaluate the final products each machine produces and determine whether they will have commercial value. Research their markets, and ensure the machine selected can create products whose quality is good enough to meet market demands.
• Waste management system: A tire recycling machine is part of a larger waste management system. Ensure that its feeding, sorting, processing, and extracting technologies easily integrate with other machines—like conveyor belts and shredders—and that they work like a well-oiled machine.
• Return on investment and carbon footprint: Calculate the return on investment based on operating costs, revenue from selling recycled products, and carbon footprint. Selecting a machine with a larger processing capacity may reduce carbon emissions and lessen the impact of climate change, largely because it can handle large volumes of tires at once, thereby decreasing the frequency of machine use.
• Supplier's after-sales support: Always prioritize a machine's after-sales service over its initial cost. Finding a local supplier who can provide timely parts and repair services is essential. Even though suppliers may initially offer a lower price, consider the long-term investment and potential complications that may arise if they cannot provide adequate technical support.
