DOING waste plastic pyrolysis plant is an environmental protection system which adopt the pyrolysis technology and catalytic breakdown reaction to convert waste plastics into renewable resources, such as pyrolysis oil, carbon black, combustible gas and so on. The obtained pyrolysis oil can be used in boiler and generators directly as fuel, or come into high ranking diesel by our pyrolysis oil distillation plant. Other names of waste plastic pyrolysis plant include waste plastic pyrolysis machine, waste plastic recycling plant, plastic to oil machine, plastic to fuel conversion plant, plastic to oil conversion machine and so on.
DOING waste plastic pyrolysis plant
Main components of waste plastic pyrolysis plant
Doing Group's waste plastic pyrolysis plant mainly includes pyrolysis reactor, oil and gas separator, vertical/horizontal condenser, water seal, vacuum device, oil tank, dust removal and deodorization device, control cabinet, heating furnace, etc.

Environmental protection configuration
In order to meet the stringent environmental assessment standards in Europe and the United States and other countries, Doing Group has adopted the concept of exhaust gas and waste water recycling as far as possible to achieve zero emissions. Through water seals, oil-water separators, tail gas deodorization device and desulfurization & purification tower, the separation of water, oil gas, and waste slag can be achieved, whereby oil gas are recovered, waste generated is recycled, and the entire production process is environmentally friendly.

The main working process of waste plastic pyrolysis plant
1. Put raw material into pyrolysis reactor by an automatic pusher. If your waste plastics is wet, you should dry first. This way can save operation time. The pyrolysis reactor is supposed to be left 1/3 space for rotating more smoothly. Then make sure the door of feed port is closed.
2. Heat pyrolysis reactor gently by burning the fuel material (coal, wood, natural gas, LPG or plastic oil generated from last batch can be choosed). The oil gas will be released when the temperature reached 160℃ (The most oil is produced at 220℃-280℃).
3. The oil gas will flow into cooling system and some of them will be cooled into liquid oil in there. Then store the liquid oil into oil tank. The left incondensable gas through tail gas cleaning and odor removal and desulfurization & purification tower will be led to the heating furnace for recycling.
4. After all the above work has been done, cool down the reactor. Then discharge the carbon black by carbon black discharge device.When all the work has been done, you can start the next batch.
