Environmentally Friendly Waste Tyre Pyrolysis Line
In recent years, with the increasing number of cars, China's waste tires have increased at an annual rate of 8% to 9%. The resulting environmental pollution, waste of resources and safety hazards have become more prominent, especially used tires. The problem of “secondary pollution” caused by processing technology and equipment in the comprehensive utilization process has become an urgent problem for the development of circular economy in China. As the pollution caused by waste tires is becoming more and more serious, the recycling of waste tires and the reuse of secondary resources have received more and more attention. In the past, waste tires were treated by open-air accumulation or landfill, heat recovery by combustion incineration, tire retreading, and production of recycled rubber. These methods have the disadvantage of wasting a lot of chemical raw materials and environmental pollution. In view of this, the environmentally-friendly waste tire pyrolysis line can process these wastes more effectively.
Thermal pyrolysis is by heating the used tires at high temperatures to break them down into fuel oil, combustible gas, and carbon black. The oil obtained by thermal cracking is similar to the characteristics of commercial fuel. It can be used for direct combustion or mixed with petroleum-extracted fuel. It can also be used as rubber processing softener. The obtained combustible gas is mainly composed of hydrogen and methane, and can be used as fuel. It is also possible to burn the heat decomposition process in situ, the obtained carbon powder can be used instead of carbon black or processed to form a special adsorbent. This adsorbent has a strong filtration effect on toxic metals such as mercury in water. In addition, the pyrolysis products are also waste steel wires.
The data shows that the waste tires can be converted to 40%-45% fuel oil after being treated by thermal pyrolysis technology. And these fuels can be used as a substitute for oil after deep processing.
