Definitions

  • the subject of the present invention is a method of heat treatment of waste, especially waste household and industrial, but not exclusively, and installation for its implementation of the kind including a rotating combustion cell in which are introduced waste by a loading end, while at the other end are collected the slag, while the gases are recovered upstream or downstream of the cell, as described in document-WO-A-8 802 284.
  • bottom ash has a content of unburnt from 2 to 10% under form of carbon.
  • This new process also aims to produce gases fuels rich in CO, CH4, various tars which are burnt at 1200 ° C in self-combustion in a room specific. These weakly charged gases pollutants due to low temperatures, require treatment whose complexity and dimensions are significantly lower than incineration.
  • the installation includes a rotating cell composed of a cylinder and of a truncated cone rotating on the same axis.
  • Pyrolysis takes place in the cylindrical part of the cell and, as it is greedy in energy, this is supplied by the coke produced by itself and whose combustion takes place in the truncated cone defined as being the pyrolysis heat generator.
  • the reduction thermal, pyrolysis / combustion of coke, takes place at countercurrent, the gases produced circulating against the current solids.
  • the fundamental characteristic of the installation of heat treatment of the waste in question resides basically in the fact that it has this area of intimate contact with waste determined by a threshold of reserved retainer between the cylindrical part and the part frustoconical of the rotating cell.
  • crossing this threshold obliges the waste, during coking, to form a volume of which the constituents are brought into close contact with each other, while receiving some oxygen.
  • the waste reaction temperature is approximately 700 ° C. This restraint, artificially created by the threshold, allows obtaining a coke which serves, in the cone generator, to fuel to provide the hot gas flow needed to pyrolysis.
  • the combustion air is distributed under ignition coke by a network of nozzles fed by channels.
  • the single figure is a schematic view of the waste heat treatment installation according to the invention.
  • reference 1 designates the rotating cell rotated by schematic mechanical means under references 2.
  • arrow 3 indicates the waste loading hopper fitted with a flap 4 and a push button 5.
  • the pyrolysis gas recovery chimney is designated by the reference 6.
  • an ashtray 7 for the evacuation of slag or coke symbolized by the arrow 8.
  • the rotating cell 1 is constituted, according to the invention, of a cylindrical part 9, constituting the pyrolyzer, associated with a frustoconical part 10 forming the generator. Between cylinder 9 and truncated cone 10 is reserved a zone 11 connecting the end 12 of the cylinder 9 and the large base 13 of the truncated cone 10. This zone 11 constitutes a waste retention threshold affecting a significant taper resulting from the difference in diameter between the cylinder 9 and the truncated cone 10.
