DOING continuous pyrolysis machine in China

In the growing field of waste recycling and energy recovery, continuous pyrolysis technology stands out. As a global supplier of pyrolysis machines, DOING Group offers advanced continuous pyrolysis machines that deliver unparalleled efficiency, sustainability, and profitability. If you're considering upgrading from a traditional batch system or considering an investment recovery solution, this introduction to our continuous pyrolysis machines will show you why it's a smart choice.

DOING continuous pyrolysis machine

A continuous pyrolysis machine is an advanced system designed to continuously thermally decompose waste materials (such as scrap tires, plastics, rubber, oil sludge, and other organic solids) into valuable end-products such as fuel oil, carbon black, and syngas. Unlike batch and semi-continuous pyrolysis machines, which require frequent cooling, unloading, and reheating cycles, a continuous pyrolysis system is equipped with automatic feeding and unloading devices and can operate 24/7 for approximately 40 days.

Machine Configuration

DOING Group's continuous pyrolysis machines are meticulously designed for seamless operation and optimized output. The core components include:

Automated Feeding System: The process begins with a multi-stage feeding mechanism, including a hydraulic feeder, screw conveyor, and sealed inlet. Waste materials are pre-shredded and fed continuously into the reactor at a controlled rate. This system uses variable-speed motors and sensors to prevent overfeeding, ensuring even distribution and avoiding pressure buildup.

Horizontal Rotary Reactor: The heart of the machine is a double-layer, horizontal cylindrical reactor made from high-grade boiler steel (Q245R, Q345R or other stainless steel materials) with 14-20mm thickness for durability under 300-400°C temperatures. Its internal design features a patented spiral decoking system that facilitates material flow and prevents residue adhesion. The reactor's length-to-diameter ratio optimizes residence time, allowing precise control over decomposition for maximum yield.

Heating and Combustion System: Efficient heating is provided by a multi-fuel burner (supporting wood, coal, diesel, natural gas, or syngas recycling) connected to the reactor's outer jacket. Our latest heating system is a hot air furnace. This heating method can not only maintain a high temperature continuously, but also avoids direct contact with open flames, resulting in a longer service life for the reactor.

Condensation and Oil Collection System: Vapors from the reactor are piped through a multi-stage condenser (horizontal and vertical types) cooled by water circulation. This system separates pyrolysis oil with a yield of 40-50%, while non-condensable gases are captured for reuse.

Discharging and Cooling System: At the reactor's outlet, a water-cooled screw discharger continuously removes carbon black at temperatures below 100°C, preventing re-polymerization.

2 Improved Economic Efficiency: Maximizes Return on Investment (ROI): High daily output and continuous operation directly contribute to increased revenue streams.

3 Reduced Labor Costs: Automation significantly reduces the need for labor, thereby lowering operating costs.

4 Energy Self-Sufficiency: Utilizing syngas for internal heating significantly reduces external energy consumption and costs.

5 Superior Safety and Environmental Compliance: Sealed System Design: Our continuous pyrolysis machines utilize a fully sealed system from feeding to unloading, ensuring zero leakage of hazardous gases and dust. This ensures a safe working environment and prevents environmental contamination.

6 Advanced Residue Management: A specialized reactor and piping design prevents clogging and residue buildup, ensuring long-term smooth operation and minimizing maintenance downtime.

7 Comprehensive Off-Gas Treatment: All process gases undergo rigorous treatment before discharge to meet environmental standards.

8 Precise Process Control and Product Quality: Adjustable Temperature and Residence Time: Operators can fine-tune these critical parameters to precisely control the pyrolysis process and optimize the quality and yield of fuel oil, carbon black, and syngas.

9 Adaptability and Reliability: Capable of processing a wide range of organic wastes such as waste tires, rubber, plastic, aluminum-plastic composites, medical waste, household waste, acrylic, resin powder, fiberglass, epoxy resin, photovoltaic panels, high-temperature die head materials, fan blades, rosin, diatomaceous earth, etc., our equipment flexibly meets diverse waste management needs.
