In August 2020, Mingjie Group helped a Thai customer upgrade batch pyrolysis plant to semi-continuous waste plastic pyrolysis plant. The original pyrolysis unit was purchased from South Korea to process waste plastics from landfills. After the upgrade, the processing capacity of the waste plastic pyrolysis plant was expanded from 5T/D to 10T/D.
In order to solve the problem of low efficiency of the original pyrolysis device, Mingjie Group equipped it with an automatic feeding and automatic slag discharging system. It can realize feeding at high temperature, greatly improving efficiency.
In terms of environmental protection, the semi-continuous pyrolysis plant performs well. During the treatment process, it has extremely strict control over pollutants. The pyrolysis reaction is carried out in an oxygen-free or low-oxygen sealed environment, which greatly reduces the generation of harmful gases. At the same time, the gas generated by pyrolysis is discharged after purification, which has less pollution to the environment.
Waste Plastic Pyrolysis Plant Manufacturer
Mingjie Group is a professional waste plastic pyrolysis plant manufacturer. We are committed to providing customers with one-stop waste pyrolysis solutions and establishing long-term cooperative relationships with customers.
From the appearance, the semi-continuous waste plastic pyrolysis plant consists of pyrolysis reactor, screw feeder, water-cooled screw slag discharger, oil-gas separation system, and flue gas purification system.
The pyrolysis reactor is the core component of the plastic pyrolysis plant, usually made of stainless steel material. It can withstand high temperature and high pressure working environments.
The screw feeder is installed at one end of the pyrolysis furnace, and the motor drives the spiral blade to rotate. So that the plastic particles are smoothly fed into the pyrolysis reactor.
The water-cooled screw slag discharger is installed at the other end of the pyrolysis furnace, responsible for timely discharge of the slag after pyrolysis.
The oil-gas separation system are used to collect and separate the oil and gas generated during the pyrolysis process. In order to ensure the environmental protection of the production process. The oil and gas produced during the pyrolysis process can be cooled and separated to obtain fuel oil and syngas, which are valuable energy resources.
The harmful gas emissions generated by the semi-continuous pyrolysis equipment are extremely low. After being treated by an advanced flue gas purification system, it can meet strict environmental emission standards.
Comparison Between Semi-continuous and Batch Pyrolysis Plant
Semi-continuous waste plastic pyrolysis plant has shown excellent efficiency in processing volume and production cycle. The waste processing capacity of semi-continuous pyrolysis plants can reach 15T/D. The actual processing capacity of batch pyrolysis equipment of the same size can reach 10T/D.
In terms of production cycle, batch equipment usually takes a long time to complete a series of operations such as feeding, pyrolysis, discharging and cooling. Batch pyrolysis equipment may take 24 hours or even longer from feeding to discharging of waste plastics, plus cooling time.
The semi-continuous waste plastic pyrolysis plant adopts a spiral feeding and water-cooled spiral slag discharging system. The feeding and discharging process can be carried out almost uninterruptedly, greatly shortening the production cycle. Compared with the batch pyrolysis equipment, the semi-continuous equipment only takes about 16 hours to process the same waste plastic, and the production efficiency is increased by about 33%.
