A pyrolysis machine is a complex system designed to thermally decompose materials in the absence of oxygen, producing valuable by-products such as oil, gas, and carbon black. The primary components of a pyrolysis machine include the feeding system, pyrolysis reactor, discharging system, syn-gas recycling system, and de-dusting system. These components work together to ensure efficient waste treatment, energy recovery, and compliance with emission standards. The feeding system delivers raw materials to the reactor, where high-temperature pyrolysis occurs, while the discharging system handles the solid residues. The syn-gas recycling system recovers combustible gases for reuse, and the de-dusting system ensures that emissions meet environmental standards. Additional components like the cracking furnace, heating system, and condenser further enhance the system's functionality.

Key Points Explained:

1. Feeding System:

   • The feeding system is responsible for delivering raw materials (e.g., waste plastics, tires, or biomass) into the pyrolysis reactor.
   • It operates in a fully sealed manner to prevent the escape of gases and ensure safety.
   • Automation in the feeding system enhances efficiency and reduces manual labor.

2. Pyrolysis Reactor:

   • The reactor is the core component where high-temperature pyrolysis occurs, typically in the range of 300-900°C.
   • Inside the reactor, raw materials undergo thermal decomposition, resulting in the breakdown of complex molecules into simpler compounds.
   • The reactor is designed to withstand high temperatures and pressures, ensuring durability and safety.

3. Discharging System:

   • The discharging system handles the removal of solid residues, such as carbon black, from the reactor.
   • It often includes a water-cooling pipe to cool the residues before storage or further processing.
   • This system ensures the continuous operation of the pyrolysis machine by efficiently removing by-products.

4. Syn-Gas Recycling System:

   • The syn-gas recycling system captures and recycles combustible gases produced during pyrolysis.
   • These gases, primarily composed of methane, hydrogen, and carbon monoxide, can be used to heat the reactor, reducing the need for external fuel.
   • This system enhances the overall energy efficiency of the pyrolysis process.

5. De-Dusting System:

   • The de-dusting system is crucial for purifying the emission gases before they are released into the atmosphere.
   • It removes particulate matter and harmful pollutants, ensuring compliance with environmental regulations such as EU emission standards.
   • This system is essential for minimizing the environmental impact of the pyrolysis process.

6. Cracking Furnace:

   • The cracking furnace is an additional component that facilitates the thermal cracking of larger hydrocarbon molecules into smaller, more valuable ones.
   • It works in conjunction with the pyrolysis reactor to enhance the yield and quality of the pyrolysis products.

7. Heating System:

   • The heating system provides the necessary thermal energy for the pyrolysis process.
   • It can be powered by external fuel sources or by the combustible gases recovered from the syn-gas recycling system.
   • Efficient heating is critical for maintaining the optimal temperature within the reactor.

8. Condenser:

   • The condenser is used to cool and liquefy the vapor-gas mixture produced during pyrolysis, resulting in the collection of pyrolysis oil.
   • In some designs, the condenser may be excluded if the primary goal is to obtain solid residues, and the vapor-gas mixture is burned in the furnace.
   • The condenser plays a key role in maximizing the recovery of valuable liquid products.

9. Energy Module (Furnace):

   • The energy module, often integrated with the reactor, provides the heat required for the pyrolysis process.
   • Some designs combine the reactor and energy module to reduce energy losses, although this may complicate temperature control and require higher-quality materials.
   • The energy module is essential for maintaining the continuous operation of the pyrolysis machine.

10. Driving Device, Base, Main Furnace, and Casing:

    • The driving device ensures the mechanical operation of the pyrolysis system, such as rotating the reactor in some designs.
    • The base provides structural support for the entire system, ensuring stability during operation.
    • The main furnace houses the pyrolysis reactor and is designed to withstand high temperatures and pressures.
    • The casing encloses the system, providing insulation and protection from external elements.

By understanding these components, a purchaser can make informed decisions about the type of pyrolysis machine that best suits their needs, ensuring efficient waste treatment, energy recovery, and compliance with environmental standards.
