Waste plastic to oil machine

Waste plastic to oil machine is able to heat waste plastics through high temperature crack into oil, non-condensable gas and carbon black. As we all know, plastic not only brings convenience to our life, but also brings great trouble to our life. Obviously, the trouble is mainly environmental pollution. Waste plastic pollution was even once called "white pollution", attracting much attention. Now DOING group has developed waste plastic to oil machine for this practical problem.

Waste plastic to oil machine

Basic operation process of waste plastic to oil machine:

1. Collection of waste plastics

Collect a lot of waste plastic. Waste plastics that can be used as raw materials are mainly thermoplastics: there are usually three types of thermoplastics that can be used as raw materials for processing, and corresponding types of plastics will have different oil yield.

1. Polyvinyl chloride, polyethylene: PE (such as film, bottle, electrical insulation materials, handbags, pipes, drums, bottles/calcium bottles, daily necessities, etc.) pure plastic oil production rate is about 95%.

2. Polypropylene(PP): the oil production rate of polypropylene (such as film, plastic rope, tableware, POTS, barrels, furniture, bags, hats, car bumpers, etc.) is 90%.

3. Polystyrene(PS): Oil production rate (such as electrical appliances, stationery, cups, food containers, electrical shells, electrical accessories, foam products, toys, etc.) is 90%.

2. Pretreatment

A dryer is used to remove the water from the waste plastic so that it can be quickly cracked in the reactor. The larger plastic products are crushed into small pieces by plastic crusher, so that the contact area can be increased and the cracking reaction efficiency can be improved.

3. Feeding

Use automatic feeder to transfer the processed waste plastic to the reactor.

4. High-temperature heating

Continuous heating, waste plastics begin to undergo crack reaction with the increase of temperature. When the temperature reaches a certain level, waste plastics will be cracked into oil gas.

5. Cooling

Condense the oil gas into liquid oil and collect it into the oil tank. For non-condensable but combustible oil gas, directly into the reactor for combustion.

6. Slag discharge

When the reaction is finished, carbon black is dicharged and collected.

Advantage of DOING Waste plastic to oil machine 

Advantages of DOING waste plastic to oil machine:

1.High safety

The pyrolysis reactor of the waste plastic to oil machine is equipped with a sealing system around it, which can prevent air from entering and ensure the safety of the whole plastic pyrolysis process.

2.High oil yield

The circulating water cooling system is an important part of the waste plastic pyrolysis system. The cooling area of the waste plastic to oil machine is sufficient to fully cool down the oil gas and then improve the oil yield.

3.Good environmental protection

With the circulating water cooling system, the water discharge is almost zero. For the tail gas, DOING’s waste plastic to oil machine specially designed tail gas treatment system used to treat the tail gas, and the treated gas can be directly discharged into the air without causing pollution.

The use of waste plastic to oil machine to achieve the national and government advocated by the energy recovery and recycling. It will benefit future generations.
