1. A device for continuous low-temperature pyrolysis, which continuously supplies a waste tire chip, performs low-temperature pyrolysis to generate carbon black and a pyrolysis gas, and condenses the pyrolysis gas to generate oil, the device comprising:
a waste tire chip supply module configured to supply the waste tire chip;
a pyrolysis module configured to pyrolyze the waste tire chip supplied from the waste tire chip supply module to generate the carbon black and the pyrolysis gas;
a conveyor configured to convey the carbon black generated by the pyrolysis module to an outside of the pyrolysis module;
a carbon black recovery module configured to convey and store the carbon black, which is conveyed by the conveyor, into a carbon black storage tank;
a condenser configured to condense the pyrolysis gas generated by the pyrolysis module to generate the oil; and
an oil recovery tank configured to recover the oil generated by the condenser,
wherein for continuously supplying the waste tire chip by an intake method and a blowing method, the waste tire chip supply module includes:
a waste tire chip supply hopper configured for inputting the waste tire chip into a pyrolysis reactor of the pyrolysis module;
a waste tire chip silo configured for temporarily storing the waste tire chip supplied from the waste tire chip supply hopper, and supplying the waste tire chip into a first conveyor of the pyrolysis module;
a silo selection valve configured for supplying the waste tire chip by alternately selecting the waste tire chip silo so that the waste tire chip is continuously supplied into the first conveyor; a back filter configured for collecting (adsorbing) and filtering out a foreign substance introduced into the waste tire chip silo; and
a waste tire chip supply blower configured for sucking air introduced into the waste tire chip silo, and blowing the waste tire chip together with the air into the waste tire chip silo to supply the waste tire chip and the air,
wherein the waste tire chip silo is installed in a plurality of parallel structure,
wherein a waste tire chip supply blocking unit configured for selectively supplying or blocking the waste tire chip is installed in a lower portion of the waste tire chip silo,
wherein a nitrogen gas inlet is installed in a lower portion of the waste tire chip silo to prevent an explosive reaction caused by an introduction of the air into the pyrolysis reactor of the pyrolysis module,
wherein the waste tire chip supply blocking unit configured for supplying a waste tire chip into the pyrolysis reactor in a state that nitrogen gas (N2) has been supplied into the pyrolysis reactor, and a waste tire chip supply blower is driven to re-suck air from a back filter module, and blow and feed the waste tire chip together with a sucked air into the waste tire chip silo, and the air inside the waste tire chip silo is sucked and removed to supply only the waste tire chip into the pyrolysis reactor and block introduction of the air,
wherein the carbon black recovery module includes:
a carbon recovery hose connected to a carbon black discharge part of the conveyor at a gap (G) to introduce external air;
a carbon black recovery silo connected to the carbon recovery hose to recover and store the carbon black;
a carbon black collection blower configured for sucking the carbon black into the carbon black recovery silo through the carbon recovery hose, such that a vacuum pressure (negative pressure) is formed inside the carbon black recovery silo, and the carbon black is collected while the external air is sucked through the gap (G);
a back filter configured for filtering out a foreign substance inside the carbon black recovery silo; and
an actuator configured for controlling the gap G,
wherein a movable flange is formed in the carbon recovery hose, and a screw rod of the actuator is coupled to the movable flange in a screw structure, so that as the actuator rotates the screw rod, the movable flange moves up and down (in the drawings') to adjust a size of the gap G, in which a black carbon suction amount is adjusted by adjusting an external air introduction amount while expanding or reducing the gap G by control of the actuator, and thus the carbon black is recovered.
