Abstract
This invention discloses a method for extracting carbon black from waste steel-wire tyres. The method comprises: acid washing the waste steel-wire tyres, placing in a reaction kettle, and heating to obtain carbon black. The method avoids cutting and pulverization procedures. The fuel gas produced during pyrolysis can be directly used for heating the reaction kettle, thus lowering fuel consumption.
Description
Technical field
The present invention relates to the extracting method of carbon black, particularly a kind of novel method of extracting carbon black from damaged tire.
Technical background
Carbon black has a wide range of applications at glue, print field, utilizes damaged tire to produce carbon black, has great significance to saving petroleum resources.In general, damaged tire extracts carbon black, insert hot cracked acquisition in the reactor after damaged tire need being cut apart, pulverized, this respect has many relevant patents to come out, as notification number is the patent application of CN1117517A, a kind of processing method of catalytic pyrolysis waste rubber and equipment, provide damaged tire preferably and cut apart, pulverized the processing method of inserting hot cracked output carbon black and oil product in the reactor, combustion gas, but to rail tyre, cut apart, pulverize very difficult, if, then can't make full use of extracting carbon black from scrap rail tire by above-mentioned technology and method.
Summary of the invention
The object of the present invention is to provide a kind of method of extracting carbon black from scrap rail tire, realized the thermo-cracking of whole steel scrap wire tire in reactor.
The present invention is achieved in that
A kind of method of extracting carbon black from scrap rail tire is characterized in that: at first with the steel scrap wire tire with 13% dilution heat of sulfuric acid pickling 10 minutes, put into reactor again and be heated to 260 ℃, the gas mixture of output flows out by pipeline; Continue to be heated to 420 ℃, oil gas has gone out, and forms carbon black, naturally cooling in the reactor.
The present invention has following advantage:
1, the steel scrap wire tire need not to cut apart, pulverize, through pickling directly into reactor, saved cut apart, the pulverizing program.
2, the combustion gas of output in the heat scission reaction is directly used in heating of reactor, has reduced the consumption of fuel.
3, byproduct is thick oil and steel wire, and good utility value is all arranged.
Embodiment
The invention will be further described below in conjunction with embodiment.
At first the dilution heat of sulfuric acid pickling with 13% in pickling tub of whole steel scrap wire tire was taken out in 10 minutes, put into reactor by the diameter cover and be heated to 260 ℃, the output gas mixture enters refrigerating unit by pipeline, the cooling back forms oil and combustion gas, oil separates through tripping device with combustion gas again, oil flows out from gas and oil separating plant, combustion gas enters the combustion chamber participation burning of reactor again by the anti feedback device from gas and oil separating plant, continue to be heated to 420 ℃, oil gas has gone out, carbon black forms in the reactor, gets the carbon black finished product behind the naturally cooling.
Claims (3)
1, a kind of method of extracting carbon black from scrap rail tire is characterized in that: at first with the steel scrap wire tire with 13% dilution heat of sulfuric acid pickling 10 minutes, put into reactor again and be heated to 260 ℃, the gas mixture of output flows out by pipeline; Continue to be heated to 420 ℃, oil gas has gone out, and forms carbon black, naturally cooling in the reactor.
2, the method for extracting carbon black from scrap rail tire according to claim 1 is characterized in that: above-mentioned tire with pickling is mounted in the reactor by diameter.
3, the method for extracting carbon black from scrap rail tire according to claim 1 and 2 is characterized in that: form oil and combustion gas by the effusive gas mixture of pipeline through cooling, separation, combustion gas enters the reactor combustion chamber and participates in burning.
