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.
