Description

Normal pressure Continuous Heat cracking junked tire extracts the equipment of oil plant
Technical field
The present invention relates to a kind of apparatus for thermal cleavage, especially the equipment of thermo-cracking junked tire powder, extraction oil plant.
Background technology
CN103589445A discloses the innoxious continuous pyrolysis device of a kind of junked tire powder, it comprises powder screw transfer roller, preheating chamber, heating type screw conveyor, Oil/Gas Pipe, carbon black worm conveyor and condenser, arranges several worm conveyors side by side and fuel chambers in preheating chamber.Junked tire powder sends into the worm conveyor in preheating chamber through powder screw transfer roller, after fuel chambers preheating, then send into heating type screw conveyor and carry out abundant thermo-cracking, the oil gas produced after thermo-cracking sends into condenser through Oil/Gas Pipe, becomes oil plant after condensation; Noncondensable gas is sent to fuel chambers as fuel; Carbon black after thermo-cracking is discharged through carbon black worm conveyor.The defect that this device exists is: in technique, be provided with twice heating (i.e. preheating and heating), extract oil gas more after the heating.But the temperature that it does not disclose preheating and heating is how many respectively, and how to control, particularly the main fuel of preheating is the self-produced noncondensable gas of this device, and the amount of this noncondensable gas is both unknowable, uncontrollable again, and then preheating temperature is unknowable, uncontrollable, and then heating cannot compensate the temperature of preheating, cause its temperature of whole thermal cracking processes unknowable, uncontrollable, thermal cracking temperature is too high or too low all can be able to have a negative impact to pyrolysis effect; Secondly, twice heating process will inevitably establish twice heating facility, not only makes that device is complicated, cost occupies high, also because preheating uses fuel, is bound to produce discharge; Again, the fuel first of preheating is not noncondensable gas, if Sweet natural gas or coal gas, then the use of this device is restricted, and maybe can cause investment; Finally, oil gas enters condenser and does not use external force to carry, and uses known condenser, and pre-heating fuel uses noncondensable gas, and these all imply that its oil yield is very low.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide the equipment that a kind of normal pressure Continuous Heat cracking junked tire extracts oil plant.
The object of the present invention is achieved like this:
1, junked tire powder (hereinafter referred to as powder) sends into operating apparatus for thermal cleavage through material loading screw feeder (being also screw conveyor), said apparatus for thermal cleavage is, several heating coil feeding machines are end to end, reciprocating layout from top to bottom, saidly end to endly refer to that the discharge port of a screw feeder docks with the opening for feed of next screw feeder, electrothermal tube is laid at the surface uniform of each screw feeder pipeline, with the bandage that lagging material is made, electrothermal tube is wrapped on the surface of steel pipe again, on the top of each screw feeder tube chamber, a pyrolysis gas pipeline is set, after the air outlet parallel connection of all pyrolysis gas pipelines, be communicated with prolong, the turning axle gear of all screw feeders engages successively, the turning axle gear of one of them screw feeder engages with driving toothed gear, said operation refers to that driving toothed gear rotates, to electrothermal tube energising, the temperature of electrothermal tube is 450-550 DEG C,
2, send into the powder in operation in apparatus for thermal cleavage, advanced successively until apparatus for thermal cleavage discharge port by several screw feeders, become carbon black; Powder is by several screw feeder Continuous Heat cracking in this process, in each screw feeder tube chamber produce pyrolysis gas and enter respective pyrolysis gas pipeline;
3, from apparatus for thermal cleavage discharge port carbon black out, be admitted to carbon black feed bin through the screw feeder with refrigerating unit, the said screw feeder with refrigerating unit is that screw feeder duct wall is sandwich structure, notes recirculated cooling water in interlayer;
Simultaneously, under the effect of induced draft fan, prolong is entered from pyrolysis gas pipeline pyrolysis gas out, said prolong is composed in series by front coil pipe, left pipe connecting, threeway straight pipe, right pipe connecting and rear coil pipe, and wherein the tie point of each coil pipe and adjacent pipe connecting is positioned at the port of respective coil pipe orlop pipe; A coil pipe is put, top-off cycle water in each cooling tank in each cooling tank; Left pipe connecting, threeway, right pipe connecting are positioned at outside cooling tank, and V-shaped, threeway is positioned at lowest part; Said induced draft fan is arranged on the port of rear coil pipe the superiors pipe.Pyrolysis gas is in front coil pipe, a part is condensed into oil plant, flow out from the bypass of threeway when flowing through threeway, the pyrolysis gas be not condensed is on oil plant, after threeway straight pipe enters, coil pipe continues condensation, the oil plant that condensation generates in rear coil pipe, flows to threeway under gravity until flow out.
Compared with CN103589445A, positively effect of the present invention is: change laser heating into by twice heating, eliminates preheating chamber and combustion chamber, make pyrolytic process and equipment simpler, and owing to using electric power, both can realize pyrolysis temperature controlled, not produce discharge again; In laser heating process, pyrolysis gas pipeline is set at the screw feeder of each heating, namely in pyrolytic process, extracts pyrolysis gas continuously, substantially increase pyrolysis gas extracted amount; The pyrolysis gas produced through twice condensation, substantially increases oil yield under the promotion of induced draft fan.
