Pyrolysis is a thermochemical decomposition of orgnic material at elevated temperatures in the absence of oxygen. Pyrolysis typically occurs under pressure and at the operating temperatures at 430℃. Pyrolysis is a special case of thermolysis, and is the most commonly used for organic materials, being, therefore, one of the processed involved in charring. In general, pyrolysis os organic substances produces gas and liquid products and leaves a solid residue richer in carbon content. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization. The process is used heavily in the chemical industry, for example, to produce charcoal, activated carbon, methanol, and other chemicals from wood, to convert ethylene dichloride into vinyl chloride to make PVC, to produce coke from coal, to convert biomass into syngas, to turn waste into safely disposable substances, and for transforming medium-weight hydrocarbons from oil into lighter ones like diesel or gasoline. All these specialized used of pyrolysis may be called various names, such as dry distillation, destructive distillation, or cracking, but all same principle.
For us, we mainly specialized in manufacturing and supplying waste tire/plastic/rubber pyrolysis plant, mostly for processing the rubber products to get fuel oil. On one hand, with the modernization of the society, rubber industry develops at a rapid speed, rubber manufactures are widely used in many field of life. On the other hand, the pollution of scrap rubber or plastics is increasing for its difficulty in disposing safely, which is also called “Black Contamination”, has become a big threat to the environment and is getting increasingly serious.
In the early years, the most commonly used pyrolysis plant is mainly the batch operation process, which has low investment but complicated operation process and high labour cost. With the technology improving and customers’ requests, we DOING Company developed a new technology continuous pyrolysis plant. This continuous pyrolysis plant has fully automatic process, which can be controlled by PLC system or computer, thus to save the labour cost. And with the automatic and continuous feeding and discharge system, it can make the the pyrolysis system keep running 24/7 without stop, thus to save the valuable time and energy which are consumed in the batch manual operation system.
Fuel oil application
1. Fuel oil (45%-50%): Oil from fully automatic continuous tyre pyrolysis plant can be used as industrial fuel for burning.
2. Carbon black (30%): First, Carbon black from fully automatic continuous tyre pyrolysis plant is crude. You can sell it to the brick factory as internal combustion or to the factory which need it as raw materials, such as shoe, tire, cable and sealant companies. Second, could make further process, make carbon black powder into carbon black briquette, and use it for burning.
3. Steel wire (10-15%): It can be sold to the iron and steel company directly.
4. Waste gas (5%): we have a special design could recycling it into fire furnace for burning.
