The performance indexes of vulcanizate is still not so good as the damaged tire before processing, while production process high temperature high pressure dynamic desulfurization in glue
Journey also has energy consumption height, and added value is low, generates the disadvantages of secondary pollution outstanding problem.
Tire has very high calorific value (2937MJ/kg), and the calorific value of per kilogram is higher than timber by 69%, higher than bituminous coal
10%, it is higher than coke by 4%, therefore, directly as the heat energy utilization method (cement kiln, Industrial Boiler, electricity generation boiler etc.) of fuel
It is that waste tire integrated treatment utilizes an important method.But hypertoxic carcinogenic substance dioxin is also easy to produce during oxy combustion,
Therefore its high equipment cost and complicated fume treatment auxiliary must be configured in order to reach the environmental requirement that can be discharged.
The pyrolysis of damaged tire refers to that under anaerobic or anoxic operating condition and temperature appropriate, main chain has unsaturated bond in rubber
Macromolecule fracture, product is mainly monomer, dimer and fragment, and product is polymerized to a variety of alkene again, thus deviate from volatilization
Property substance and the process for forming solid carbon, product are mainly pyrolysis oil, solid and not condensation combustible gas based on coarse carbon black.It presses
Pyrolysis temperature can be divided into high temperature pyrolysis (>1000 DEG C), medium temperature pyrolysis (600~700 DEG C) and low temperature pyrogenation (<600 DEG C).It is pyrolyzed work
The advantage of skill is, due to being anaerobic decay, is conducive to mitigate the secondary pollution to atmospheric environment, can control the production of dioxin
Raw and pollution;The harmful components such as sulphur, heavy metal in waste are largely fixed in solid black wood charcoal and effective recycling.
