Description
TECHNICAL FIELD The present invention relates to a pyrolysis apparatus for industrial waste, and more particularly, to a continuous pyrolysis apparatus for a waste tire configured to pyrolyze a waste tire while continuously introducing a waste tire, thereby separating and extracting an available energy source.
Polymer wastes, including waste tires, are being incinerated and buried in large quantities worldwide. There is no case of using heat of combustion by incineration, but there is a great concern about environmental pollution and the recycling efficiency of resources is extremely low.
Therefore, a technology for pyrolyzing waste tires in an oxygen-free state to extract recyclable resources has been proposed (refer to Korean Patent Registration Nos. 10-0619393 and 10-1147788). And the waste tires are heated in an anaerobic atmosphere to extract oil that can be used as fuel. However, the conventional pyrolysis apparatus can not use a conventional tire, and in most cases, it has a batch type process, so that the productivity is low. This is because the heat loss is large and the time required for cooling and reheating is required because the process is required to lower the temperature every time the material is introduced into the pyrolysis furnace, to remove the air, and to heat again.
In response to such a problem, Korean Patent Laid-Open No. 10-2011-0089924 proposes a continuous pyrolysis system. However, this has a problem in that energy consumption is increased by using scrapped tires in advance and using electricity as a heat source.
