In the process of rubber pyrolysis into oil, waste rubber materials are heated in an oxygen-free or oxygen-deficient environment, undergoing thermal decomposition to generate a variety of valuable products, such as fuel oil, carbon black, and synthesis gas.
Changes that occur during rubber pyrolysis:
1. Thermal decomposition:
At high temperatures, rubber molecules are destroyed and decomposed into smaller hydrocarbon molecules.
2. Product generation:
These decomposed molecules will form a variety of products, mainly including:
Fuel oil: can be directly burned as an industrial fuel, or distilled to obtain non-standard diesel, and then further processed by refineries to produce commercial diesel.
Carbon black: It is a solid substance produced during the pyrolysis process and can be used as a colorant, enhancer, etc.
Synthesis gas: It is a mixture of various gases, the main components of which are hydrogen and carbon monoxide, which can be used as a fuel or chemical raw material.
Working process of waste rubber pyrolysis equipment:
- Feeding: Put the whole tire or tire fragments into the reactor.
- Pyrolysis: Pyrolysis is carried out at high temperature to decompose the tire into oil and other products.
- Oil-gas separation: The flue gas generated by pyrolysis flows through the oil and gas separator, the heavy oil sinks and is stored in the residual oil tank, and the gaseous components enter the cooling system.
- Cooling: The gaseous components pass through the cooling system and become liquid oil.
- Oil-water separation: Liquid oil is separated from water, light oil is stored, and a small amount of oily wastewater is atomized and used as fuel.
- Discharge: After the reactor is cooled, carbon black and steel wire are discharged.
The whole process of waste rubber into oil will inevitably produce some pollution. However, HUAYIN Waste Rubber Pyrolysis Equipment is equipped with an advanced dust removal system, and sewage/waste gas can be discharged in compliance with standards after treatment.
