Abstract

The present invention discloses a system for recycling used tires. The disclosed system for recycling used tires comprises: a pyrolysis furnace that recycles inputted used tires using a carrier gas and decomposes the used tires through direct heating; and an oil collecting unit that collects oil by cooling and condensing hot steam generated by the pyrolysis furnace. The system also includes a carrier gas circulation line and a carrier gas circulation and supply device. The carrier gas circulation line circulates through the pyrolysis furnace and the oil collecting unit. The carrier gas circulation and supply device is connected to the carrier gas circulation line and comprises a sensing element that measures both the temperature inside the pyrolysis furnace and the pressure inside the carrier gas circulation line. In addition, the carrier gas circulation and supply device collects and stores a non-condensable gas generated by the pyrolysis furnace and selectively supplies the non-condensable gas to the pyrolysis furnace.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a system for recycling waste tires enabling to extract various energy sources from the waste tires by pyrolyzing the waste tires through a heating method, and more particularly, to a system for recycling waste tires enabling to achieve economical management and to enhance yield to extract oil by recycling a non-condensed gas produced during the pyrolyzing process as carrier gas.

[0003] 2. Description of the Related Art

[0004] Recently, the demand for tires is rapidly increasing according to the increasing of the demand for vehicles, and therefore the amount of the waste tires is also increased.

[0005] As well known, the waste tires are mainly composited high polymer compounds, and their caloric value is about 34 MJ / kg which is higher than 29 MJ / kg of a standard caloric value. Further, the general composition of tires is 43.5wt % of styrene-butadiene copolymer, 32.6wt % of carbon black, 21.7wt ...
