Abstract

The invention relates to a process for preparing carbon black by utilizing electric arc to crack waste and old tires, which utilizes a closed container and electric arc to regulate and control oxygen to constitute an electric-arc cracking furnace, and waste and old tires are cracked in the electric-arc cracking furnace. Steel lines in the waste tires are fused in the electric-arc temperature, steel ingots are directly prepared to recycle, the chemical bond of rubber in the waste and old tires are fractured under the electric-arc temperature and are cracked into carbon black, carbon monoxide, hydrogen gas and the like. The carbon black which is prepared by the upper method has the advantages of big specific surface area, high activity and high utilization valve, the surface characteristic of the carbon black which is originally added in the waste and old tires is restored and improved after the electric-arc temperature. Gases such as carbon monoxide, hydrogen gas and the like which are produced in the electric-arc temperature can be directly utilized by city gas after the process of de-oiling and desulfurizing, the process has no waste gas to be discharge and no pollution.

Description

The method of preparing carbon black by electrocracking waste and old tyre
The present invention relates to a kind of method of harmless treatment junked tire, especially the cracking junked tire is produced the method for carbon black and town gas.
Background technology:
The main method of handling junked tire at present is to utilize sealed furnace, and indirect heating destructive distillation junked tire makes rubber vaporization, cracking in the junked tire, obtains fuel oil, combustible gas and carbon black.Aforesaid method, because indirect heating, therefore heat is imitated low; Simultaneously, the steel wire in the junked tire is clipped in the charcoal layer, needs once more mechanical separation to reclaim, and pollution is arranged; The carbon black specific surface that pyrolysis temperature obtains down is little, and utility value is low.
Summary of the invention:
Task of the present invention provides a kind of pollution-free, and the cracking junked tire is directly produced steel ingot and reached the method for town gas.
Technical scheme: for solving above-mentioned task, the solution that the present invention adopts is: utilize airtight container and electric arc, regulation and control oxygen, arcing pyrolyzer, cracking junked tire in arc cracking furnace.Steel wire in the junked tire melts under arc temperature, directly produces steel ingot and reclaims; Rubber in the junked tire is under arc temperature, and chemical bond rupture is cracked into gases such as carbon black, carbon monoxide and hydrogen; The carbon black that add in waste tire rubber Central Plains under arc temperature, is directly deviate from from rubber; Carbon black is with gas flow such as carbon monoxide and hydrogen; Gas such as carbon monoxide and hydrogen is deviate from carbon black through temperature regulation, is recovered as town gas through de-oiling, desulfurization again.The Residual oil of deviating from returns arc cracking furnace again, continues to be subjected to electrocracking.Said process operation capable of circulation.
Owing to adopted arc cracking furnace in the above-mentioned solution, therefore regulation and control oxygen do not have exhaust gas emission and pollution; Arc temperature is the high-end temperature of essential substance in the cracking junked tire, therefore, adopts directly cracking junked tire of arc temperature, and the fusing steel wire reclaims steel ingot; The carbon black of producing under the arc temperature, specific surface area is big, and is active strong, the utility value height.The carbon black that add in junked tire Central Plains, through behind the arc temperature, surface property is repaired and is improved; Gases such as carbon monoxide that arc temperature produces down and hydrogen are through de-oiling, desulfurization is handled can be directly as the town gas utilization.
