Step by Step Pyrolysis Process Introduction Video

In this video, we walk through the pyrolysis process using DOING Company's pyrolysis equipment. The focus is on the steps of operation, from preparing materials to collecting outputs. This overview is based on our standard waste pyrolysis production line setup, which handles materials like waste tires and plastics efficiently.

Step 1: Feedstock Preparation（Mainly For Semi-Continuous/Fully Auotmatic Pyrolysis Process）

Before any material enters a pyrolysis reactor, proper preparation is often key to maximizing operational efficiency and final product quality. For waste tires, DOING pyrolysis plant includes options to remove steel wires and grind the tires into smaller rubber pieces. Plastics are typically shredded into uniform sizes. This step ensures even heating and better results inside the reactor. Preparation can be adjusted depending on the material type and the specific setup of your pyrolysis plant.

Step 2: Feeding the Reactor

Once prepared, the feedstock moves to the feeding system. DOING pyrolysis plants use reliable methods like screw conveyors or hoppers to load materials into the reactor without interruptions. For some setups, manual feeding works well for smaller batches. This stage keeps the process running smoothly by delivering consistent amounts of material.

Step 3: The Pyrolysis Reaction

At the heart of the DOING pyrolysis plant is the reactor, where the main transformation happens. The system heats the feedstock to temperatures between 300°C and 600°C in an oxygen-free environment. Heating can come from various fuels like coal, wood, fuel, natural gas, and the reactor is well designed to maintain stable conditions. As heat builds, the organic components break down through thermal decomposition, producing oil vapors, syngas, and solids.

Step 4: Product Separation and Collection

After the reaction, the outputs from the reactor enter the separation phase. Oil vapors pass through condensers in the pyrolysis system, where they cool and turn into pyrolysis oil, while non-condensable gases are separated. These gases can be piped back to heat the reactor, helping to reduce overall energy use. At the same time, solid leftovers like carbon black collect at the reactor's base and are discharged through the residue outlet for further handling.

Step 5: Exhaust Gas Handling

DOING pyrolysis plants include systems to clean exhaust gases before release. These filters and scrubbers remove impurities, ensuring compliance with global EIA standards. This keeps the operation compliant and minimizes emissions during the full process.
