Description

A kind of integrated apparatus that achievable waste tire is cracked and is quickly cooled down completely
Technical field
The invention patent relates to waste tire cracking technique fields, and in particular to a kind of achievable waste tire cracks completely With the integrated apparatus being quickly cooled down.
Background technology
The cracking of waste tire is to solve waste tire to cause one of effective ways of environmental pollution.Waste tire is by splitting The cracking in host is solved, obtained pyrolysis product is carbon black and fuel gas, be can be obtained using subsequent processing after carbon black cooling It is worth higher activated carbon, various oil products and on-condensible gas can be obtained using subsequent processing after fuel gas cooling.Crack skill Art has begun the recycling field applied to waste tire, and related tire pyrolysis technology is also being constantly progressive at present.
Invention CN104031672A provide a kind of continuous thermal-cracking method and device of waste tire, and this method includes following Step:(1) waste tire material preheats to (15-25) minute at 230-250 DEG C, extracts under vacuum and is generated in warm Gas;(2) material that step (1) obtains is warming up to 340-360 DEG C, and cracks (8-12) minute at 340-360 DEG C, make day T PNR cracks, and the gas generated in cracking process is extracted under vacuum;(3) material that step (2) obtains is warming up to 440-460 DEG C, and (8-12) minute is cracked at 440-460 DEG C, so that butadiene rubber and butadiene-styrene rubber is cracked, cracking process is extracted under vacuum The gas of middle generation;(4) material that step (3) obtains is warming up to 540-560 DEG C, and (8-12) is cracked at 540-560 DEG C Minute, so that the carbonaceous sediment of carbon blacksurface is cracked, the gas generated in cracking process is extracted under vacuum.This method and device can The deposit for effectively removing carbon blacksurface improves the activity and quality of carbon black, and the company of waste tire cracking is realized with low energy consumption Continuous production.
It invents CN108018062A and a kind of waste rubber cracking method and system is provided, waste old is sequentially sent to anaerobic Or the Low Temperature Thermal cracking room of Hypoxic habitats, high temperature pyrolysis room, microwave cracking room;Wherein, waste old is in Low Temperature Thermal cracking room In carry out thermal cracking under the 200-400 DEG C of environment, carry out hot tearing under 500-800 DEG C of environment in high temperature pyrolysis room Solution carries out microwave cracking in microwave cracking room under 500-800 DEG C of environment;The cracked oil gas quilt generated in cracking process Continuous discharge Low Temperature Thermal cracking room, high temperature pyrolysis room, microwave cracking room;The solids generated in recycling cracking process.This hair It is bright effectively to reduce energy consumption in cracking process, improve waste tire lysis efficiency and cracking black carbon quality.
Although existing patent is improved on waste tire cleavage method and cracking apparatus, waste tire is improved Lysis efficiency reduces energy consumption when cracking.But there are still many technologies for waste tire continuous cracking equipment conventional at present Problem, the carbon black for one of the important products of cracking are all to use to be directly over after after-treatment device cools down to be discharged immediately Easily there is waste tire carbon black of output after cracking host cracking and cracks incomplete ask in the processing method of cracker Topic.In addition, the carbon black not cracked completely is quickly cooled down in after-treatment device, the directly cooling caused heat of high temperature carbon black will also result in Cold oil is attached to the problem on carbon black pellet when amount loss and cooling.Although existing patent can improve the quantum of output of carbon black, But all have ignored to pyrolysis product it is correct processing and recycling, cannot solve these problems so that the quality of cracking black carbon by To influence, while reducing the quantum of output of cracking oil gas again, also because thermal loss causes the waste of the energy.
