Small pyrolysis machine – BLJ-16 is a cost-effective solution for waste management. Through pyrolysis technology, BLJ-16 can realize resource utilization and treatment of waste such as plastics, oil sludge, and tyres. This pyrolysis process produces end products like pyrolysis oil and carbon black, both of which have wide applications in industrial and commercial sectors. At present, this equipment has become the choice of many investors for waste recycling projects.
Typically, pyrolysis equipment is composed of feeding system, reactor, condenser, discharger, and waste gas treatment system.
⚙️ Working Principle: Small pyrolysis plant is designed to operate in batch mode, processing one furnace of raw materials per day. In each batch run, raw materials such as plastics, oil sludge, or tyres are fed into the reactor and undergo pyrolysis for a specific period. Once the pyrolysis stage concludes, the entire operation of BLJ-16 shifts into the cooling phase. After cooling, the by-products are discharged and the system is reloaded with raw materials to start the next batch.
While different feedstocks bring distinct processing challenges, our BLJ-16 small pyrolysis machine incorporates specialized upgrades to overcome typical bottlenecks and unlock higher profitability:
3000 tons/year processing capacity
Applies catalytic dewaxing technology to break down heavy wax components during pyrolysis, effectively preventing wax oil condensation and blockage for stable, continuous operation.
4000 tons/year processing capacity
Employs precise thermal control during pyrolysis to reduce TPH in carbon black, followed by grinding and pelletizing to upgrade it into high-value N330/N550/N660 grades.
6000 tons/year processing capacity
Combines decanter centrifuge + thermal washing + pyrolysis technology to remove impurities and reduce thermal resistance, significantly lowering the risk of coking and improving reaction stability.

Note:
The end products produced by small scale pyrolysis equipment of each raw material are different. In particular, the reaction of each raw material produces syngas. It is reused in the pyrolysis reaction. The remaining products have a wide range of applications in various fields.
Use a burner to preheat the small pyrolysis reactor. Generally, natural gas, diesel, and heavy oil are used as preheating fuels.
When the temperature of the reactor reaches 180℃, the reaction begins. When the reaction reaches 280-350℃, the reaction tends to stabilize. The entire reaction involves the following processes:
When the oil yield decreases and the oil turns dark brown, the oil extraction process is essentially complete. After the reaction is completed, the small pyrolysis plant is cooled down. This is to prepare for the subsequent discharging.
Small pyrolysis machine adopts flexible component layout and modular design. Therefore, you can customize the configuration according to site conditions and production requirements. By the way, these configuration options are an important part of small pyrolysis plant cost.
The feeding system of small scale pyrolysis equipment can be divided into three categories according to working efficiency: manual, hydraulic and screw feeding:
| Feeding Method | Feeding Size | Working Efficiency |
|---|---|---|
| Manual | less than 1.2m | low |
| Hydraulic | less than 1.2m | high |
| Screw | less than 5cm | high |
The reactor of a small scale pyrolysis unit is the core component for the reaction. The reactor material must be selected based on the characteristics of different pyrolysis feedstocks. For example, plastics require a higher pyrolysis reaction temperature, which demands greater heat resistance from the reactor material. The following are three commonly used materials.
| Furnace Material | Features | Suitable Raw Materials |
|---|---|---|
| 310S Stainless Steel | Can withstand high temperature of 1035℃; High temperature oxidation corrosion resistance; Acid corrosion resistance. | waste plastic |
| 304 Stainless Steel | Can withstand high temperature of 600-700℃ | oil sludge, scrap tyre |
| Q345R Steel | Can withstand high temperature of 450℃ | oil sludge, scrap tyre |
After pyrolysis, the solid residue needs cooling. The discharge system of small-scale pyrolysis equipment uses a water-cooled screw discharger, available with one or three units. The 3 screw discharger choice has a shorter cooling time for the reactor and the solid residue.
| Discharging Method | Furnace Cooling Temperature | Cooling Time | Solid Residue Temperature |
|---|---|---|---|
| 1 screw conveyor | 50-60℃ | long | 100-150℃ |
| 3 screw conveyors | 150℃ | short | 50-80℃ |
For small plastic pyrolysis machine, catalytic tower can solve the problem of wax oil blocking pipeline during pyrolysis process. Thus, it improves reaction efficiency and oil quality.
For tyre pyrolysis machine equipped with screw feeding, tyre need to be processed into rubber powder. The equipment can achieve tyre cutting, crushing and steel wire removal, etc.
This equipment further purifies the pyrolysis oil through distillation. The pyrolysis oil is converted into naphtha and non-standard diesel, which has higher utilization and commercial value.
In order to meet the high emission standards in some regions, we provide high-end exhaust gas treatment equipment. The exhaust gas treated by this equipment can meet EU standards.
The function of the nitrogen system is to introduce nitrogen for gas replacement before ignition and discharge. Through nitrogen replacement, the residual combustible oil gas in the reactor can be effectively removed. This can prevent the flash explosion of the reactor, thereby ensuring the safe and stable operation of the small pyrolysis machine.
The floating seal technology adopts a sealing method that combines carbon fiber and high-temperature soft filler. Compared with the traditional graphene packing sealing technology, this combined sealing form has high temperature resistance, corrosion resistance and wear resistance. This technology can stably guarantee the sealing of pyrolysis process for a long time.
The intelligent control mode integrates PLC/DCS systems with optional IoT monitoring, ensuring efficient, automated operation. Real-time data insights enable quick adjustments, reduce manpower needs, and improve the working environment. This advanced control approach enhances overall operational efficiency while giving customers greater visibility and flexibility in managing production.
Excess syngas may cause safety hazards of small pyrolysis unit overpressure and storage. Emergency incidents such as power outages that may occur during equipment operation. To prevent these potential safety hazards, the flare system can be quickly activated in the event of pressure or power abnormalities. This ensures the safe discharge of syngas and prevents system overpressure.
