Waste plastic pyrolysis recycling is an effective means of treating waste plastics through pyrolysis equipment. Plastic pyrolysis equipment converts waste plastics into high-value products under high temperature and oxygen-free conditions. It provides an effective way to solve plastic pollution and recycle resources.

Plastics are composed of high molecular polymers, which are connected by chemical bonds to form long chain structures. The principle of waste plastic pyrolysis recycling is to apply high temperature to waste plastics in an oxygen-deficient or low-oxygen environment.

Plastic Pyrolysis Recycling Process

The pyrolysis plant is the core equipment for recycling waste plastics. During the plastic waste pyrolysis recycling process, the pretreated waste plastics are fed into the pyrolysis reactor. In an oxygen-free or low-oxygen environment, the waste plastics are heated to a specific temperature range by external heating. Under this high temperature condition, the chemical bonds in the plastic molecules are broken, and the high-molecular polymers are gradually decomposed into low-molecular compounds.

The plastic pyrolysis equipment is heated to 300℃-800℃, the chemical bonds within the plastic molecules are broken, and the original long-chain macromolecules are broken into relatively small molecular fragments. These small molecular fragments exist in the form of gas, liquid oil and solid carbon black. 

The pyrolysis plastic plant separates the oil and gas through the condensation system and purification system, and converts them into pyrolysis oil and synthesis gas.

Advantages of Plastic Waste Pyrolysis Equipment

First, its investment is relatively small and the plastic pyrolysis plant cost is low. The plastic pyrolysis plant mainly includes pyrolysis reactor, condensation and cooling system, heating temperature control device and feeding and discharging device. For some enterprises with relatively limited funds or small plastic recycling plants, it has certain appeal.

Secondly, the pyrolysis process principle is easy to understand and master, and the pyrolysis machine operation is relatively simple. Mingjie batch pyrolysis equipment is equipped with a dewaxing device, which can effectively avoid the pipe blocking problem during the plastic pyrolysis treatment process.

Finally, in order to improve the purity of pyrolysis oil, Mingjie distillation equipment can further distill and refine black pyrolysis oil into bright diesel or gasoline base oil.
