Retort/furnace for processing large scrap tires

Abstract

Disclosed is a batch pyrolysis reactor for the recovery of pyrolysis products by batch processing waste material. The reactor includes a heating chamber, a removable retort for insertion into and withdrawal from the heating chamber, and a control unit for cycling the temperature of waste material in the pyrolysis chamber. The retort includes a pyrolysis chamber having an opening for receiving and extracting solids.

1 . A furnace vessel that provides a heat source to a retort vessel. 
     
     
         2 . A retort vessel that contains scrap tires that is inserted into claim No.  1 . 
     
     
         3 . A lid that seals the retort and furnace vessels stated in claims No.  1  and  2 . 
     
     
         4 . A heat source included in claim No.  1  that provides the heat needed to conduct the pyrolysis process used in claim No.  2 . 
     
     
         5 . Spacers to lift the bottom located tire in the retort and separate any additional tires placed on top or on the sides placed in claim No.  2 . 
     
     
         6 . Nitrogen injection system applied to claim No.  2  to evacuate all oxygen contained within claim No.  2  prior to the application of the heat source in claim No.  4  as contained within claim No.  1 . 
     
     
         7 . A circulation fan contained within claim No.  2  and mounted within the lid of claim No.  3 . 
     
     
         8 . Multiple individual turning vanes to guide internal circulation within claim No.  2  and supporting circulation generated by claim no.  7 . 
     
     
         9 . The ability to insert smaller tires within the void spaces of the larger tires while still operating in the same manner. 
     
     
         10 . The ability to use the retort vessel without the very large tires and utilize with numerous bales of smaller tires while still operating in the same manner. 
     
     
         11 . A batch pyrolysis reactor for the recovery of pyrolysis products by batch processing waste material comprising,
 a heating chamber having a chamber opening, having a removable lid for obtaining access to the chamber opening, having heating ports for receiving combusted gases for heating the heating chamber and having an exhaust for exhausting combusted gases,   a removable retort for insertion into and withdrawal from the heating chamber through the chamber opening and for enclosure in the heating chamber by the lid for heating of the retort, the retort including,
 a pyrolysis chamber having an opening for receiving and extracting solids, 
 a port for porting pyrolysis gas from the reactor during a pyrolysis period to leave a solid residue in the pyrolysis chamber after the pyrolysis period, 
   a control unit for cycling the temperature of waste material in the pyrolysis chamber over a pyrolysis period whereby after the pyrolysis period the retort is removed from the heating chamber and the solid residue is removed from the retort.
