Description
The present invention relates to a kind of method and device thereof with damaged tire system petrol and diesel oil and carbon black.
Along with socioeconomic growing, all produce a large amount of waste rubbers every year, and wherein the overwhelming majority is a damaged tire.According to the data introduction in 92 years of document statistics, 2,000,000 tons of damaged tires of the annual generation of the European Community, the U.S. is about 2,000,000 tons, and Japan is 700,000 tons, and USSR (Union of Soviet Socialist Republics) is 1,500,000 tons, and Canada is 220,000 tons, and the U.S. is 400,000 tons, and China is about 400,000 tons every year.Most damaged tires are accumulated in the out of door place, are difficult to degraded, very easily cause fire and produce a large amount of pollutents.And contain a large amount of useful industrial product such as carbon black, oil product, inflammable gas etc. in the damaged tire.And itself be exactly a kind of fuel of high heating value, its thermal value is generally 40MJ/kg, typical the elementary composition of damaged tire is: charcoal 85%, hydrogen 8%, sulphur 1.2%, ash content 5%, the annual depleted tire in the whole world is 9,000,000 tons, so just be equivalent to 9,000,000 tons of annual loss crude oil, day by day under the intense situation, utilize damaged tire to be extremely important at the present energy.But in the prior art, be batch still formula operation mostly, working pressure and temperature are higher, moreover, the circulation heating of heating kettle and cooling loss a large amount of heats, therefore cause energy consumption height, process cost height.
Goal of the invention of the present invention provides the operation of a kind of continuous production, pressure is low, cracking temperature is low, energy consumption is low damaged tire system petrol and diesel oil and the method and the device thereof of carbon black.
The method of damaged tire system petrol and diesel oil of the present invention and carbon black is carried out as follows:
(1) scrap tire powder is broken into the 2-10cm fragment, cleans then, dry;
(2) material after will drying is sent in the pyrolysis reactor, logical carrier gas;
(3) pyrolysis reactor heats, and is warming up to 370-500 ℃, and residence time of material is 5-20 minute, obtains liquefied gas, petrol and diesel oil mixing oil and thick carbon black;
(4) liquefied gas returns pyrolysis reactor as thermal source, and thick carbon black is through iron removal by magnetic separation, and screening obtains the finished product carbon black, and the petrol and diesel oil mixing oil is removed impurity and moisture through adsorbents adsorb, enters distillation tower;
(5) mixing oil that enters distillation tower obtains gasoline, solar oil, heavy gas oil through fractionation.
Aforesaid carrier gas is nitrogen, water vapor, combustion exhaust.
In the anterior carrier gas that can feed some amount of pyrolysis reactor heating,, and guarantee that thermal cracking gas leaves the heating zone to avoid thermo-cracking for the second time in the regular hour with the air of carrying secretly in the eliminating material.
Aforesaid sorbent material is a gac, activated carbon fiber etc.
Aforesaid fractionation can adopt the prior art in the refining of petroleum to realize.
In order to reach the purpose of aforesaid method, must the design specialized pyrolysis reactor.
The present invention is made up of cylindrical shell, feeder, heat air inlet, ash discharging hole, oil product vapor outlet, carbon black outlet, tail gas outlet and screw rod for the designed pyrolysis reactor of aforesaid method, it is characterized in that described screw rod is that front end is to become tight spiral shell square, the spiral shell square of middle part for widening, terminal no screw thread is equipped with the carbon black plate washer in the cylindrical shell of screw rod end.
Screw front end in the pyrolysis reactor is for becoming tight spiral shell square, to play the effect that the anti-gas of sealing flows backwards, middle part spiral shell square is widened so that cracked gas has an expansible space, and in cylindrical shell, take cracked gas product out of reactor rapidly under the effect of carrier gas, in case oil product gas cracking for the second time, the terminal no screw thread of screw rod separates carbon black rapidly.
Method and apparatus of the present invention compared with prior art has following advantage:
(1) realized the serialization of reaction process.
(2) working pressure is a normal pressure, and temperature of reaction is low, and the operating time is short, and power consumption is few.
(3) introduced gas of carrier gas, split product mixed oil and gas yield is improved, the carbon black quality improves.
(4) sulphur content of mixing in the oil product reduces.
Describe method of the present invention and pyrolysis reactor in detail below by drawings and Examples.
Fig. 1 is the structural representation of pyrolysis reactor of the present invention.
Fig. 2 is the A-A view of Fig. 1.
As shown in the figure, 1 is that an end is connected with gear-box 2, the cylindrical shell of other end sealing, 3 are ends with Gear in the gear-box 2 connects and is positioned at the screw rod of cylindrical shell 1, produces before this screw rod to be the tight spiral shell square of change, in Section is for widening the spiral shell square, terminal no screw thread, the 4th, the charging on the cylindrical shell 1 that gear-box 2 one ends are arranged Mouthful, the 5th, the air inlet on the cylindrical shell between screw rod front portion and the middle part, the 6th, be positioned at screw rod 3 middle parts With heating air inlet mouth 7, tail gas outlet 8 and ash discharging hole 9,10,11 heating jacket, the 12nd, be positioned at spiral shell Oil product vapor outlet on the bar 3 terminal cylindrical shells 1, the 13rd, be positioned at the carbon black outlet on the screw rod 3 terminal cylindrical shells 1, The 17th, be in screw rod 3 ends, the carbon black plate washer in the cylindrical shell 1.
