Abstract
The pollution-less waste tyre treating and reusing method includes the steps of cracking in a reactor by adding molecular sieve and AlCl3 as catalyst at 200-550 deg.c and 0.03 MPa, separating and collecting oil and gas produced in the cracking; separating steel wire and other iron containing matter with electromagnet from the residual dry and heavy matter; and dry distilling the residum at 500-700 deg.c and 0.03 MPa to obtain carbon black. The said process can eliminate environmental pollution caused by waste tyre and reuse the resource.
Description
Technical field:
The present invention relates to the nuisanceless processing and utilizing method of a kind of junked tire.
Background technology:
At present junked tire does not have good treatment to utilize method, abandons everywhere and is difficult to natural degradation, has caused the severe contamination to physical environment, and this also is a kind of waste of resource simultaneously.
Technology contents:
The purpose of this invention is to provide the nuisanceless processing and utilizing method of a kind of junked tire, to alleviate to the pollution of environment and the waste of resource.
Processing method of the present invention comprises following process:
Catalytic cracking:
Junked tire is inserted reactor, adds 0.05～0.1 part molecular sieve and AlCl
3As Cuiization agent, molecular sieve and AlCl
3Ratio be 1: 1～3, be that 200～550 ℃, pressure are lower than and carry out cracking under the 0.03MP condition in temperature, oil, gas that cracking produces are separated, and are collected;
Dried, heavy substance is handled:
Residue behind oil, the gas is done with having separated, the steel wire in the heavy substance etc. is drawn with electro-magnet and separated, surplus materials is inserted 500～700 ℃ of temperature, pressure be lower than to do under the 0.03MP condition to slip and obtain carbon black, the carbon black that obtains can be inserted the granularity that is ground to needs in the spheroidal graphite machine according to service requirements and be got final product.
The oil of separating in the above-mentioned catalytic cracking program is preferably inserted in the following subnormal ambient of 200～400 ℃ of temperature, 0.03MP and is carried out secondary cracking, obtains refining fuel oil, and residue can be used as rubber filling oil.
The present invention carries out nuisanceless processing and utilizing with junked tire, has eliminated junked tire and has arbitrarily abandoned the environmental pollution that caused and the waste of resource, turns waste into wealth.
Description of drawings:
Accompanying drawing is a processing sequence synoptic diagram of the present invention.
