Semi-continuous Pyrolysis Plant

Semi-continuous pyrolysis plant is a popular type of Beston. This type of equipment can process waste continuously. The degree of automation is higher than that of batch equipment. This model can realize automatic feeding and automatic discharging. It can help customers save a part of labor. At the same time, the efficiency of the entire pyrolysis process is improved, and the oil yield is higher than that of the batch type. If you’re interested in the type, keep watching.

What is Semi-continuous Pyrolysis Plant?

Semi-continuous pyrolysis plant refers to the pyrolysis equipment that can feed and discharge automatically and continuously. The machine converts some of the waste into alternative fuels under sealed, oxygen-free conditions. Besides, this machine can harmlessly dispose of some waste, like oil sludge.

This production line is generally divided into automatic screw feeding system, pyrolysis system, automatic water cooling discharge system, combustible gas recovery system, and de-dusting system. For these systems and other extra systems, Beston provides customized services. Please take a look at the following site picture of the Netherlands.

Video of Beston Semi-continuous Pyrolysis Machine

Look at the four sets of BLL-16 Beston semi-continuous pyrolysis plant installed in China in 2021 from the following video. These equipment are used to treat local oil sludge. The treated sludge will not pollute the local environment. In the video, these plants were installed under the guidance of Beston experienced engineers. The installation process was smoothly. Please watch the video.

Raw Materials for Semi-continuous Waste Pyrolysis Plant

There are many types of raw materials that can be processed by this type of waste pyrolysis equipment, including tires, plastics, sludge, and rubber. When feeding, there are requirements for the size of the tire waste. The tires are generally tire powder/blocks. Please see the classification of raw materials.

Why Choose Beston Semi-continuous Pyrolysis Machine?

High Efficiency Compared with batch equipment, this equipment can process three pyrolysis furnaces of raw materials in two days.

High Oil Yield Since this type requires the size (small) of raw materials, the oil yield of this equipment is higher than that of batch equipment.

Short Pyrolysis Process The time for this model to process a batch of raw materials (14.7/batch) is much shorter than that of the batch type (23h/batch).

Low Work Intensity Since this equipment adopts automatic screw feeding and automatic water-cooling slag removal, the whole production line has low requirements on working strength. high degree of automation.

Good Working Environment When using this device, it is not necessary to draw out the wire inside the furnace. At the same time, the carbon black is discharged by water-cooling and low-temperature sealing.

How to Operate Semi-continuous Waste Pyrolysis Machine?

  • Make sure the raw material fits the size of the incoming material. The raw materials will be transported to the main pyrolysis furnace by the screw feeding system. The whole conveying process is well-sealed. Little air gets in.
  • Add suitable fuel and heat the main furnace. When the temperature rises, the raw materials gradually undergo chemical and physical reactions in the main furnace. Eventually, pyrolysis oil (carbon black) is gradually precipitated. Raw material size is small. The whole pyrolysis process is very sufficient. High oil yield.
  • The recyclable combustible gas in the main furnace enters the gas bag and condensation pipe. The treated recyclable combustible gas can be directly used as fuel for heating the main furnace. The excess combustible gas will be burned through the exhaust chamber. This system can help customers save part of their fuel costs.
  • The exhaust gas will be discharged up to the standard after being treated by the condenser and the dust removal tower. Beston can customize the dedusting tower according to the situation of the customer’s country to meet the different needs of customers.
