structure OF rotary kiln pyrolysis reactor
The structural design of a rotary kiln pyrolysis reactor directly affects the pyrolysis efficiency and product quality. A typical pyrolysis rotary kiln mainly includes the following parts:
Cylinder body
Material: Usually made of high-temperature and corrosion-resistant steel, lined with refractory bricks or ceramic coatings.
Design feature: The cylinder is usually arranged at an angle of 3 ° -5 °, relying on a rotating belt to move the animal material from the high end to the low end.
Heating system
Direct heating: The burner directly transfers heat to the cylinder and material.
Indirect heating: transferring heat through thermal oil, steam, or electric heating media, which is more suitable for volatile or flammable materials.
Cooling system
The solid product is cooled by a spiral cooler or water cooling system and discharged to protect the safety of subsequent equipment and personnel operations.
Drive system
Rotating mechanism: The motor and reducer drive the cylinder to rotate, and frequency conversion control is often used to adjust the speed.
Sealing device: The cylinder is equipped with high-temperature sealing devices at both ends to prevent oxygen from entering.
Exhaust gas treatment system
The condensing device is used to separate oil and water from volatile gases. Non-condensable gases are treated or reused through combustion.
Control system
It is equipped with PLC or DCS control system to achieve automated operation and monitor key parameters such as temperature, pressure, and speed.
pyrolysis process OF rotary kiln pyrolysis reactor
Pyrolysis is a chemical process that decomposes organic matter through thermal energy, mainly occurring in the temperature range of 200 ° C to 900 ° C. The rotary kiln pyrolysis reactor provides a closed or semi-closed environment, limiting oxygen supply to ensure that the main reaction is pyrolysis rather than combustion.
The core process of rotary kiln pyrolysis reactor is to decompose organic matter into gas, liquid, and solid three-phase products through high temperature, oxygen deficient or anaerobic environment inside the kiln. The specific process flow is as follows:
STEP1: Material pretreatment
Crush and dry the raw materials to the appropriate particle size and moisture content (generally moisture<15%). According to the pyrolysis requirements, catalysts or additives can be added to improve pyrolysis efficiency or optimize product distribution.
STEP2: Thermal decomposition process
Drying stage (<200 ° C): Water evaporates and the moisture content of the material decreases. Thermal decomposition stage (200-500 ° C): Organic matter undergoes thermal decomposition to produce volatile gases and solid carbon. Deep carbonization stage (>500 ° C): Solid carbonization further decomposes volatile substances to produce high-purity carbon.
STEP3: Cooling and discharge
The produced carbon material is cooled by a cooling device and discharged. Volatile gases enter the condensation system for separation and recovery of oil and gas.
STEP5: Exhaust gas treatment
Non-condensable gases enter the burner or recycling system as heat sources or chemical raw materials to reduce environmental pollution
