Waste plastic pyrolysis plant

Plastic products are widely used, everywhere plastic waste. There is a serious impact on 

our environment from both visual pollution and potential hazards. Visual pollution means 

the aesthetic perception of a living city that is affected by waste plastic everywhere. 

Potential hazards mainly refers to waste plastics resistant to degradation, affecting crop 

nutrient and water absorption, reduce production; otherwise, animals will be unconscious 

death. The recycling of waste plastics has increasingly become an important part of 

environmental protection. DoingGroup has developed a waste plastic pyrolysis plant in 

addition to plastic waste. The device can also handle waste solid waste organic waste such 

as waste tires / waste rubber / waste acrylic / garbage / medical waste / oil shale, the 

operation of the device is as follows:

Waste plastic pyrolysis plant

1. The waste plastics and other organic solid waste by the conveyor belt to the bunker by 

the automatic feeding system to the cracking furnace, rotating the main furnace can control 

the positive and negative reversing switch control switch to adjust the organic raw 

materials in the main furnace of the material distribution, the total amount of material 

control in the total volume below two thirds, close the feed sealing door, and then open 

the heating system.
2. When the temperature reaches about 150 ℃, gas will be generated (most of the gas is the 

exhaust gas at this time). When the temperature reaches about 220 ℃, oil and gas will 

start to enter the multi-function separator. After the multi-function separator, there will 

be some oil separation down, the pipeline into the residual tank, the pump into the 

cracking furnace to continue heating cracking.
3. Oil and gas into the cooling system through the multi-function separator, the condensed 

oil and water flows into the oil-water separator through the pipe for oil-water separation 

measurement. Under the action of negative pressure, the non-condensable gas enters the 

micro-vacuum system through the cooling system piping and is filtered again.
4. The pyrolyzed flue gas enters the powerful atomization dedusting tower through the flue 

pipe to spray dust and cool down, and is discharged into the industrial exhaust gas 

purifier by the induced draft fan, finally reaching innocuous discharge.

Waste plastic pyrolysis plant is not only able to degrade the plastic waste in life, reduce environmental 

pollution, but also produce more renewable energy to ease the energy crisis, more and more 

because of its own advantages as follows:
1.Reactor is made according to the standard of pressure production, using 16mm thick 

boiler special steel and arc compression head, can withstand high pressure and high 

temperature.
2. 2 High-standard 3-step welding process, not easy to crack, long service life.
3. Pinion rotation device, power is small, not directly contact the reactor, less heat 

transfer, not easy to deformation.
4. The three-stage cooling system uses tube condensation, also known as a heat exchanger, 

and is currently the most commonly used and best performing condenser in the oil industry. 

Can ensure that the cracked oil and gas fully cooled, high oil yield.
5. Safety device oil-water separator, water seal, vacuum device, to ensure safe and 

efficient operation of equipment.
After the reactor cracking will produce lysis oil, carbon black, combustible gas.
Fuel Oil: Steel Plant, Boiler Heating, Heavy Oil Generator, Cement Plant.

Fuel oil application

Carbon black: pressure ball burning, refining flour. Which refined flour and can be used for new tires, rubber, plastic, paint manufacturing.

Carbon black application

Combustible gas: It is recycled by the waste plastic pyrolysis plant  for combustion heating of the reactor.
Waste plastics and other waste is the simplest way to deal with landfill and simple 

incineration. Landfills need a lot of valuable land resources. Since the development of 

waste rubber, waste plastics , fuel oil pyrolysis equipment has become a common research and 

attention of all levels of government issues. It not only saved valuable land resources for 

human beings, but also created a new topic of new energy. Waste plastic pyrolysi plant  investment occupies 

450 square meters of production space, plant simple, rich source of raw materials, low 

cost, large profit margins, the recovery of fuel oil is widely used. Running one day there 

will be tens of thousands of dollars of revenue. Domestic customers can recover all the 

investment within three months, Southeast Asia investment customers a month and a half to 

recover all the investment.
