Waste tire recycling system

Abstract

Disclosed is a waste tire recycling system. More particularly, the present invention relates to a waste tire recycling system having a pyrolysis furnace in which waste tires injected are recycled with a carrier gas and decomposed by a direct heating method, an oil-collecting means for cooling and condensing hot steam generated from the pyrolysis furnace and collecting oil, and a carrier gas recycling line through which a carrier gas is recycled back into the pyrolysis furnace via the pyrolysis furnace and the oil collecting means, the waste tire recycling system comprising a carrier gas feeder connected to one end of the carrier gas recycling line to selectively feed a carrier gas by controlling a valve, the carrier gas feeder having a filling element filled with a carrier gas containing at least one of methane, ethane, propane, butane, pentane, hexane and ammonia group components in a mixed form.

1 . A system for recycling waste tires including a pyrolyzing furnace which pyrolyzes the waste tires by a direct heating method using a carrier gas, an oil collecting means which cooling condenses the high temperature steam produced in the pyrolyzing furnace and collects oil, and a carrier gas circulating line which passes the pyrolyzing furnace and an oil collecting means and recycles to the pyrolyzing furnace, the system comprising:
 a carrier gas provider  50  which is connected to one end of the carrier gas circulating line (cl) and selectively provides carrier gas through the control of a valve  53 , and it is provided with an element which is filled with carrier gas consist of methane, ethane, propane, butane, pentane, hexane, ammonia based gas or composition thereof.   
     
     
         2 . The system according to  claim 1 , wherein the carrier gas provider  50  is composed of a carrier gas tank  51  which is connected to the carrier gas circulating line (cl) and which is filled with the carrier gas therein; an oxygen detector  52  which detects oxygen present in the carrier gas circulating line (cl); and an oxygen burner  30  which is connected to the oxygen detector  52 , receives the detected information, and selectively removes the oxygen in the carrier gas circulating line (cl) by burning 
     
     
         3 . The system according to  claim 1 , wherein further comprising: a carrier gas circulating provider  20  which is connected to the carrier gas circulating line (cl), provided with a sensor for measuring the temperature in the pyrolyzing furnace  1  and the pressure in the carrier gas circulating line (cl), collects and reserves the non-condensed gas produced in the pyrolyzing furnace  1  and selectively circulates it to the pyrolyzing furnace  1 . 
     
     
         4 . The system according to  claim 3 , wherein the carrier gas circulating provider  20  is pipe-connected to the carrier gas provider  50 , selectively receives carrier gas and provides the carrier gas in the carrier gas circulating line (cl). 
     
     
         5 . The system according to  claim 3 , wherein the carrier gas circulating provider  20  includes a pressure measurer  21  which measures the pressure in the carrier gas circulating line (cl) and a temperature measurer  23  which measures the temperature in the pyrolyzing furnace  1 , as a sensing element. 
     
     
         6 . The system according to  claim 3 , wherein the carrier gas circulating provider  20  includes a non-condensed gas reserving tank  27  connected to the condensed gas circulating line (cl) and selectively reserving the non-condensed gas, and control valves  25  and  29  connected to a pipe which connects the non-condensed gas reserving tank  27  to the condensed gas circulating line (cl) and they selectively provide the non-condensed gas to the non-condensed gas reserving tank  27  or provide the non-condensed gas in the non-condensed gas reserving tank  27  to the condensed gas circulating line (cl). 
     
     
         7 . The system according to  claim 3 , wherein the carrier gas circulating provider  20  provides the non-condensed gas flowing in the condensed gas circulating line (cl) in the non-condensed gas reserving tank  27  when the pressure in the condensed gas circulating line (cl) is over 100 mmAq and the temperature in the pyrolyzing furnace  1  is over 200° C. 
     
     
         8 . The system according to  claim 1 , wherein the condensed gas circulating line (cl) is installed with an oxygen removing heater  30  having a heating element which is selectively heated by an electric source to completely burn the oxygen contained in the condensed gas.
