In recent years, many people have earned lucrative profits from plastic pyrolysis plants. They want to dispose more waste plastic to get more earnings. DOING high capacity continuous plastic pyrolysis plant is the best choice, which can process 10-50 tons waste plastic per day and the whole process is controlled by PLC, thus higher efficiency and less operating costs than batch pyrolysis plant.

DOING high capacity continuous waste plastic pyrolysis plant is improved and designed on the basis of batch plastic pyrolysis, so the overall process is not much different:

1. Plastic Pretreatment

This is the first step. If your plastic has a higher water content, it has to be dried firstly. Then crush the plastic into small piece. This will not only save space but also accelerate the pyrolysis speed of waste plastics in the reactor, and in short, it can improve the operating efficiency of the equipment.

2. Feed plastic

After the above pretreatment work is completed, put the raw material into the reactor through continuous feeding system. But when feeding the waste , ensure that you have left at least 1/3 of the space in the reactor empty to allow smoother rotating.

3. Heat the reactor

Use wood, coal, natural gas LPG, wood, or any other type of fuel to heat the reactor. When the temperature reaches between 150 degrees and 200 degrees, the high capacity continuous waste plastic pyrolysis plant will release oil gas. The higher output rate occurs when the temperature hits between 280 degrees and 350 degrees.

4. Oil gas condensation

Once again, the oil gas that has been cracked enter the condensing system. When the hot oil gas meets cold, it is liquefied into fuel oil and falls into the oil tank. Our condensing system includes 2 vertical condensers, 2 horizontal condensers and 2 cooling tower, thus to get fully cooling effect and higher oil yield.

5. Discharge carbon black

After the oil gas has completely entered into the oil tank , the carbon black will be discharged by the auto screw discharger.

For the treatment of the three wastes of waste gas and waste water generated during the operation of the high capacity continuous waste plastic pyrolysis plant, DOING launched a desulfurization and deodorization tower to thoroughly help customers solve the problem of factory odors and the exhaust gas drained out meet European and American environmental protection and emission standards.
