Definitions

  • the present invention relates to the field of heat treatment of solid materials, and more particularly pyrolysis (or thermolysis) ovens intended for treat solids such as waste of any kind.
  • the ovens targeted are generally cylindrical and rotate around their axis of symmetry.
  • the calorific intake necessary for pyrolysis can consist of solids or gases in contact or not with the solids to be treated.
  • patent application FR-A- 2,668,774 shows an oven pyrolysis in which heating can be carried out outside the oven by burners supplied with pyrolysis gases; according to another embodiment, heat transfer solids are supplied in contact with the waste to be pyrolyzed in the oven itself. A additional reactor is then necessary to heat the solids heat transfer fluids.
  • This type of installation is a complex implementation, and is reveals to the heavy consumer use of energy.
  • the document DE-A- 29 03 280 discloses a compact rotary oven in which the waste to be treated successively passes through a first cylinder turning then a rotating ring coaxial with the cylinder. Waste are heated by heat transfer gases circulating around the cylinders. An external rotating envelope delimits the area of heater.
  • this type of installation remains particularly complex in terms of the shape of the cylinders; Moreover the means of heating and smoke evacuation not being problems may arise at the level of connections.
  • This type of installation like most ovens known turning points (see US-A-1 508 578), must be considered as ovens rotary external indirect heating.
  • the present invention represents an improvement of ovens known pyrolysis turning points
  • this invention avoids the problems of obstructions by solids large, inert or not yet thermally degraded; the risks of snagging are almost non-existent, very clearly reduced compared to known systems.
  • the thermal efficiency is further improved by the fact that the highest temperatures are clearly located at center of the system.
  • a solid material heat treatment oven comprising a rotating element in which said longitudinally circulates solid materials, and a heating means therefor materials, which extends longitudinally in the oven, the solid materials progressing in about two lengths to inside the rotating element.
  • the heating means is fixed, intended for channel solid materials and ensure their preheating and / or their heating.
  • the heating means is fixed, arranged coaxially and inside the rotating element so that that in the axial zone delimited by the heating means, the solid materials exhibit the highest temperatures.
  • the heating means comprises at least a tubular element whose branch (s) are parallel to the axis longitudinal of the oven, 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 of solid materials.
  • the oven according to the invention can comprise tubular elements which are independently supplied each other.
  • the oven according to the invention allows easier reuse of hot fluids than in the case of a rotary heating system; this is still a way to increase the energy performance of the installation, since it is possible to efficiently recover the sensible heat from fumes produced.
  • the heating means may constitute an element of generally cylindrical shape around or inside which resistive elements are arranged.
  • the type of oven illustrated in Figure 1 has a cylinder turning 1 with a horizontal or slightly inclined axis depending on the inventory and disposal requirements for solids.
  • This cylinder turning is mounted for example on rollers 2, themselves fixed on a base 3 which supports most of the furnace equipment.
  • Said rotating cylinder is equipped with a set 4 which ensures its rotation at a speed preferably between 0.1 and 20 rpm.
  • the cylinder is connected to a fixed part 5, via a connection 6 which ensures a complete seal between the atmosphere in the oven and outside.
  • This bond 6 can be what man of art commonly calls for a rotary joint.
  • Said fixed part 5 has an outlet 7 for the gases produced in the cylinder turning and an outlet 8 for the solids resulting from the treatment.
  • This same fixed part supports a fixed element 9, of form substantially cylindrical having one end or "outlet" 9a.
  • Element 9 preferably extends over almost the entire length of cylinder 1.
  • the device 9 is used for heating from inside the oven and channeling the waste to the end of the rotating cylinder 1 opposite to that into which said said are introduced waste to be treated.
  • the waste comes from a hopper or any storage device 10. They are introduced into the oven at a controlled flow rate thanks to a push device 11 such as shown in Figure 1, or by any other known device those skilled in the art (worm gear for example).
  • waste is more or less compacted if it present in abundant form in the raw state. Waste progress in the device 9 following a piston flow more or less compact, while being preheated. At the end 9a of the heating element 9, the waste falls by gravity into the rotating cylinder, and gradually flow longitudinally towards exit 8. The waste therefore goes back and forth in the oven.
  • the heater 9 can consist of a set of tubular elements 20 connected between them by membranes 21, ensuring continuity on the whole of the device which has a generally cylindrical shape.
  • the tubular elements are preferably grouped together by 2, 4, 6, etc. in the form of pins in which a hot fluid or in which an operation of combustion. These pins are connected to a collector 13 fixed on the fixed part 5 or placed near this fixed part 5.
  • the collector 13 includes a zone 13a for the supply in hot fluid or for air and fuel supply, and a zone 13b for the evacuation of the cooled fluid or the fumes. In no case, there is contact between the fluid or the fumes used for the heating of 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 is made up simple pins having two types of tubes 20: type tubes 22 in which the fluid circulates co-current from the waste to the interior of the device 9 and of the type 23 tubes interposed between the tubes 22 in which the fluid circulates against the current of the waste.
  • the tubes can be heated for example by combustion of a gaseous fuel.
  • the gaseous fuel can be natural gas or even gases from the pyrolytic treatment of waste, said gases having been beforehand and preferably treated to remove tar and particles that could lead to phenomena unwanted fouling.
  • the heater 9 could just as well consist of a substantially cylindrical tube, equipped with electric heating means like resistors, coiled around or inside said tube, helically, with connections carried outside to the level of a box feed.
  • the oven according to the invention is preferably intended for waste treatment at temperatures between 50 and 900 ° C, with final temperatures of the pyrolysis products in oven outlet preferably between 400 and 600 ° C.
  • the temperatures at heater 9 are included between 100 and 2000 ° C and preferably between 600 and 1000 ° C.
  • the tubes 20, 21, 22 provide a first heating (or preheating) waste by the internal face of the device 9, during progression of these inside the device 9.
  • the calorific intake 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, ie directly on the waste, i.e. on the internal wall of cylinder 1 which then returns it to the waste.
  • Part of the internal face or the external face can be hidden by an insulating mask 14, as shown in Figure 1, to control and limit the supply of heat at any point in the system.
  • the oven according to the present invention presupposes, a priori, use for heating, hot fluids or fuels clean such as natural gas or pyrolysis gases free of their tars and other particles.
  • the hot fluid can be preheated air for example at a temperature between 500 and 1000 ° C, in a boiler which burns gases of gross pyrolysis.
  • the present invention has a number of advantages, in particular with regard to a conventional installation including a heated rotating cylinder externally by burners or a heat transfer fluid which surrounds the rotating cylinder.
