Structure Composition of A Plastic Pyrolysis Plant

Plastic pyrolysis technology can convert waste plastics into fuel oil, combustible gas, and carbon black, and is widely used in the fields of environmental protection and renewable energy. The structural design of its core equipment directly affects processing efficiency, operational stability, and emission levels. Below are the main structural components of a plastic pyrolysis plant.

🔩Feeding System

The feeding system is responsible for continuously and stably feeding the pre-treated waste plastics into the pyrolysis reactor, and mainly consists of the following parts:

Screw conveyor or hydraulic feeder

Storage hopper

⚙️Pyrolysis Reactor

The reactor is the core component, where waste plastics are heated and decomposed into oil and gas vapors under oxygen-free or low-oxygen conditions.

Key structural elements include:

Reactor shell made of high-temperature-resistant steel

Internal refractory lining

Rotary or fixed reactor chamber

Sealing system

Temperature sensors

🔥Heating System

This system provides the heat required for pyrolysis and may include:

Burners

Electric heaters for small-scale units

Thermal insulation layers around the reactor

💧Condensation System

The oil and gas vapors produced by pyrolysis need to be cooled before they can be converted into fuel oil.

The system includes:

Condensers

Oil-gas separator

Circulating water cooling system

🍃Combustible Gas Purification & Recycling System

Pyrolysis produces a large amount of syngas, which can be partially recycled for heating after purification, thus reducing operating costs.

Typical components:

Gas filters

Cooling tank or cooling tower

Safety flare system

Gas recycling pipelines

⛽Oil Storage System

After pyrolysis, a small amount of carbon black or residue is produced. The residue is mainly collected in the following ways:

Automatic discharge port

Screw slag conveyor

Closed collection containers

The plastic pyrolysis plant consists of modules for feeding, pyrolysis, condensation, and exhaust gas treatment, with each component working in conjunction to ensure efficient oil production and compliance with environmental standards.
