Definitions

  • the present invention relates to the field of heat treatment furnaces for solid materials, and more particularly pyrolysis (or thermolysis) furnaces intended to treat solids such as waste of any kind.
  • this type of installation remains complex in particular in terms of the shape of the cylinders; moreover the heating and smoke evacuation means not being fixed, problems may arise at the connections.
  • This type of installation like most ovens known rotary kilns, must be considered rotary kilns with external indirect heating.
  • the present invention represents an improvement of known rotary pyrolysis ovens
  • the heating means comprises at least one tubular element whose branch or branches are parallel to the longitudinal axis of the furnace, the branch or branches are connected by membranes, the assembly having a generally cylindrical shape.
  • a heat transfer fluid circulates in the co-current and / or counter-current heating means for solid materials.
  • the oven according to the invention can comprise tubular elements which are supplied independently of each other.
  • the heating means can constitute an element of generally cylindrical shape around or inside which are arranged resistive elements.
  • the type of oven illustrated in FIG. 1 comprises a rotating cylinder 1 with a horizontal axis or slightly inclined according to the needs for inventory and flow of solids.
  • This cylinder turning is mounted for example on rollers 2, themselves fixed on a base 3 which supports most of the equipment of the oven.
  • Said rotating cylinder is equipped with an assembly 4 which ensures its rotation at a speed preferably between 0.1 and 20 rpm.
  • the transfer from the hopper to the oven takes place in a line 12, in which the waste is more or less compacted if it is present in an abundant form in the raw state.
  • the waste progresses in the device 9 according to a more or less compact piston flow, while being preheated.
  • the waste falls by gravity into the rotating cylinder, and gradually flows longitudinally towards the outlet 8. The waste therefore goes back and forth in the oven.
  • the heating device 9 can consist of a set of tubular elements 20 connected to one another by membranes 21, ensuring continuity over the whole of the device which has a generally cylindrical shape.
  • the tubular elements are preferably grouped by 2, 4, 6, etc. in the form of pins in which a hot fluid circulates or in which a combustion operation is carried out. These pins are connected to a collector 13 fixed on the fixed part 5 or placed near this fixed part 5.
  • the manifold 13 comprises a zone 13a for the supply of hot fluid or for the supply of air and fuel, and a zone 13b for the discharge of the cooled fluid or the fumes. In any case, there is contact between the fluid or the fumes used for heating the tubes 20 on the one hand, and the gases contained in the cylinder 1 and the fixed part 5 on the other hand.
  • the device 9 consists of simple pins having two types of tubes 20: tubes of type 22 in which the fluid circulates cocurrently with the waste inside the device 9 and the tubes of type 23 interposed between the tubes 22 in which the fluid circulates against the current of the waste.
  • the gaseous fuel can be natural gas or even gases resulting from the pyrolytic treatment of waste, said gases having been previously and preferably treated to remove tar and particles which could lead to unwanted fouling phenomena.
  • the heating device 9 could just as easily consist of a substantially cylindrical tube, equipped with electric heating means such as resistors, wound around or at the inside said tube, helically, with connections carried outside to the level of a power supply unit.
  • the oven according to the invention is preferably intended for the treatment of waste at temperatures between 50 and 900 ° C., with final temperatures of the pyrolysis products leaving the oven preferably between 400 and 600 ° C.
  • the temperatures at the heater 9 are between 100 and 2000 ° C and preferably between 600 and 1000 ° C.
  • the tubes 20, 21, 22 provide a first heating (or preheating) of the waste by the internal face of the device 9, during the progression of the latter inside the device 9 itself. The calorific contribution to the waste continues when these have left the device 9, via the external face of said device 9.
  • the heating of the waste is then carried out by the external face of the device 9 which emits energy by radiation, either directly on the waste , or on the internal wall of cylinder 1 which then returns it to the waste.
  • a part of the internal face or of the external face can be hidden by an insulating mask 14, as indicated in FIG. 1, to control and limit the supply of heat at any point of the system.
  • the oven according to the present invention presupposes, a priori, the use for heating, of hot fluids or of clean fuels such as natural gas or pyrolysis gases rid of their tars and other particles.
  • the hot fluid can be air preheated, for example to a temperature between 500 and 1000 ° C., in a boiler which burns raw pyrolysis gases.
  • the present invention has a number of advantages in particular with respect to a conventional installation comprising a rotating cylinder heated externally by burners or a heat transfer fluid which surrounds the rotating cylinder.
