Method and apparatus for pyrolytic decomposition of trash
Abstract
Abstract INDUSTIRAL AND MUNICIPAL TRASH IS FED INTO ONE END OF A ROTATABLY SUPPORTED,ELONGATED DRUM, WHICH TURNS AT A RELTAIVELY SLOW RATE OF ROTATION AND THE CARBONIZED RESIDUE IS DISCHARGED FROM THE OTHER END. TRAPDOOR ARRANGEMENTS AT THE ENTRANCE AND EXITS ENDS ALLOW MATERIAL TO BE FED INTO AND DISCHARGE FROM THE DRUM AS THE LATTER REVOLVES, WITHOUT OPENING THE INTERIOR OF THE DRUM TO THE ATMOSPHERE. INTERNAL GAS BURNERS AT ONE END OF THE DRUM ARE OPERATED AT THE START OF OPERATIONS TO HEAT UP THE DRUM AND CONTENTS TO HIGH TEMPERATURE,CAUSING DESTRUCTIVE DISTILLATION OF CARBONACEOUS MATERIAL WITH RESULTANT PRODUCTION OF COMBUSTIBLE GAS. FUEL SUPPLY TO THE BURNERS IS THEN CUT OFF AND AIR IS ADMITTED THROUGH BURNERS AT A CONTROLLED RATE TO MAINTAIN COMBUSTION OF GASES WITHIN THE INTERIOR OF THE DRUM TO THE EXTEND REQUIRED GAS IS EXOPERATING TEMPERATURES. EXCESS UNBURNED GAS IS EXHAUSTED AND COOLED, AND VOLATILE LIQUIDS ARE CONDENSED OUT.
