  Procédé pour la     production    continue de réactions chimiques entre corps solides en  fines particules et corps     fluides.       La présente invention comprend un pro  cédé pour la production continue de réac  tions chimiques entre corps solides en fines  particules et corps fluides, et un appareil  pour sa mise en     aeuvre.     



  Suivant ce procédé et     contrairement     aux procédés     connus    jusqu'ici clans     lesquels     (les corps     pulvérulents    et des corps fluides  devant réagir ensemble, sont     introduits    clan;  l'espace où doit. se passer la réaction au  moyen ('un appareil éjecteur utilisant la  force vive du fluide. la     réacti:)n    se passe       complètement.         < i        l'intérieur    même de l'appa  reil éjecteur, de construction appropriée, et  le produit terminé est expulsé de celui-ci par  sa propre force vive.  



  Les corps solides peuvent être amené       gracluellenment    et continuellement     \t    l'en  droit de réaction par un     moyen    connu quel  conque, tel qu'une vis sans fin, un piston  ou par la pesanteur. Ces corps, au     moment     où ils arrivent ainsi dans l'espace précédant  l'orifice d'éjection, rencontrent au moins  un jet chi fluide, qui les entraîne vers l'ori  fice commun, en causant un mélange favori-    saut la réaction.

   Ces embouchures d'où sor  tent les jets de fluide sont de préférence  disposées de façon à ce qu'il se produise  un     mouvement        tourbillonnant    du mélange,  afin     d'augmenter    le chemin que celui-ci     doit     parcourir     jusqu'à    l'orifice d'éjection et, par  conséquent, permettre à la. réaction de s'ef  fectuer entièrement à l'intérieur de l'appa  reil.  



  Afin de favoriser ce     mouvement    tourbil  lonnant et (le le soumettre à des lois vou  lues, on donne de préférence au paris de  l'appareil la     forme    d'un corps de révolution.  tel que cône,     paraboloïde    etc.  



  Le dessin annexé     représente,    à litre  d'exemple, plusieurs variantes d'un appa  reil de réaction     servant        dr    la mise en     oeuvre     du procédé.  



  La     fig.    1 est une coupe schématique d'un  appareil à chambre de réaction conique;  La     fig.    2 en est une coupe suivant     a-a;     Les     fig.    3 et     lî    se rapportent à des varian  tes de l'appareil.  



  Dans la     fig.    1, 1 désigne un tube coudé  dans lequel est disposée une vis sans fin 2.      Le tube 1 se termine par une partie de       forme    tronconique enfermant la chambre  3 de réaction. 4-4 sont des tuyères qui re  lient une     conduite    annulaire 11 à la chambre  de réaction 3 et qui sont     disposées    autour  de cette chambre     clans    une position oblique  et gauche par rapport à l'axe du tube 1. La  conduite     11    elle-même est reliée a une  tuyère 5 centrale qui pénètre clans le tube  1 et est. placée dans l'axe. de la partie ver  ticale de celui-ci.

   Cette tuyère est     terminée     par une partie effilée qui pénètre dans la  chambre 3 de réaction.  



  6     clésigne        1 orifice    de sortie de cette  chambre.  



  Pour la mise en     oeuvre    du procédé au  moyen de cet appareil, la matière pulvéru  lente, par exemple du carbure de calcium,  est amenée à l'intérieur du tube 1 par la vis  sans fin ? vers la chambre de réaction 3. A       mesure    que la matière solide     arrive,    elle est       soufflée    par les jets de fluide, de l'azote par  exemple, sortant sous pression des tuyères 4.  Grâce à la position oblique de ces dernières  par rapport à l'axe du tube 1, les jets de       fiuide    impriment aux matières pulvéru  lentes un     mouvement        tournant    dans la  chambre 3.

   Le fluide se     rnélaiige    auxdites  matières et ce mélange se dirige vers l'ori  fice 6 de la chambre 3. De cette manière, le  chemin due parcourt le mélange est     aug-          ioenté,    de sorte que la réaction a le temps  (le se produire dans la chambre 3.

   Le produit  de la réaction s'échappe soit sous     l'influence     (le sa     propre    vitesse, soit aidé par un ,jet  auxiliaire de fluide sortant de la tuyère cen  trale 5, par l'ouverture 6 en     un    jet ou une       nappe    plis ou moins conique,     suivant    la po  sition des tuyères 4, l'obliquité des parois  de la     chambre    3 et la force du jet de 5.  



  La variante de l'appareil représentée en       fig.    3 possède une chambre de réaction 7. de  section parabolique. Le but de cette forme  est     d'augmenter    de plus en plus l'angle que  fait. le courant des matières en réaction avec  l'axe de l'appareil à mesure qu'il. se rap  proche de l'orifice 6 de ce dernier, comme  cela est indiqué par le trait. mixte. De cette    manière, le temps de réaction à     l'intérieur     de la chambre 7 est augmenté et le produit  de réaction est- projeté suivant un cône  aplati en dehors de la chambre 7.  



  Dans la forme de l'appareil représentée  en     fig.    4, les tuyères sont remplacées par  une fente annulaire 8, prévue sur le pour  tour de la chambre de réaction. Le     fluide     arrive par cette fente 8 en un jet, conique et  se mélange aux corps solides qui arrivent  par le tube 1 et qui réagissent, avec le fluide.  Un jet de fluide amené. par la tuyère cen  trale 9 chasse le produit final par l'orifice  10 (le la chambre (le réaction. On peut, si  l'on veut, animer le fluide d'un mouvement.  de rotation avant. sa sortie de la fente annu  laire 8, en     l'introduisant    tangentiellement  clans la conduite annulaire 1l, de manière       i@    obtenir clans la     chambre    (le réaction une  nappe tourbillonnante.  



  Dans toutes les variantes représentées  de l'appareil, le fluide peut être réchauffé       avant        d'arriver    aux tuyères 4, 5, 9, par exem  ple, au début (le l'opération par des moyens  quelconques connus, soit, par exemple, des  arcs ou résistances électriques, soit en le  faisant passer par des tubes d'amenée, dis  posés dans les environs immédiats de la  chambre de réaction, ou des caniveaux mé  nagés dans les parois de la chambre de ré  action etc.  



  L'appareil de réaction peut être avanta  geusement disposé à l'intérieur d'un espace  fermé en forme de corps (le révolution ver  tical, dont la base est fermée par une sole  tournante refroidie servant à recueillir le       produit.    final     pulvérulent.    tandis que le  sommet. de ce corps de révolution est muni       d'ouvertures    par où s'échappe le fluide en.  excès     pour    être utilisé de nouveau, les parois  en matières réfractaires étant. pourvues de  canaux où peuvent circuler les fluides avant  de se diriger vers la chambre de réaction.  Tut autre forme de chambre peut d'ailleurs  être employée.



  Process for the continuous production of chemical reactions between solid bodies in fine particles and fluid bodies. The present invention comprises a process for the continuous production of chemical reactions between fine particulate solids and fluid bodies, and apparatus for carrying them out.



  According to this process and unlike the processes known hitherto in which (the pulverulent bodies and fluid bodies to react together, are introduced into the space where the reaction is to take place by means ('an ejector device using live force The reaction takes place completely inside the ejector apparatus, of suitable construction, and the finished product is expelled from it by its own force.



  Solid bodies can be fed smoothly and continuously into reaction by any known means, such as a worm, a piston or by gravity. These bodies, at the moment when they thus arrive in the space preceding the ejection orifice, encounter at least a fluid chi jet, which carries them towards the common orifice, causing a mixture to favor the reaction.

   These mouths from which the jets of fluid exit are preferably arranged so that there is a swirling movement of the mixture, in order to increase the path that the latter must travel to the orifice of. ejection and, therefore, allow the. reaction to take place entirely inside the appliance.



  In order to promote this swirling vortex movement and (subject it to desired laws, the bet of the apparatus is preferably given the form of a body of revolution, such as a cone, paraboloid, etc.



  The appended drawing represents, by way of example, several variants of a reaction apparatus for carrying out the process.



  Fig. 1 is a schematic sectional view of an apparatus with a conical reaction chamber; Fig. 2 is a section along a-a; Figs. 3 and 11 relate to variations of the apparatus.



  In fig. 1, 1 designates a bent tube in which is disposed an endless screw 2. The tube 1 ends with a part of frustoconical shape enclosing the reaction chamber 3. 4-4 are nozzles which connect an annular pipe 11 to the reaction chamber 3 and which are arranged around this chamber in an oblique and left position with respect to the axis of the tube 1. The pipe 11 itself is connected to a central nozzle 5 which enters the tube 1 and is. placed in the axis. of the vertical part of it.

   This nozzle ends with a tapered part which enters the reaction chamber 3.



  6 keys sign 1 outlet from this chamber.



  For carrying out the process by means of this apparatus, the slow pulverized material, for example calcium carbide, is brought into the interior of the tube 1 by the worm? to the reaction chamber 3. As the solid matter arrives, it is blown by jets of fluid, nitrogen for example, exiting under pressure from the nozzles 4. Thanks to the oblique position of the latter with respect to the 'axis of the tube 1, the jets of fluid impart to the slow pulverized materials a rotating movement in the chamber 3.

   The fluid collects with said materials and this mixture goes to port 6 of chamber 3. In this way, the path due through the mixture is increased, so that the reaction has time to take place in bedroom 3.

   The reaction product escapes either under the influence (at its own speed, or aided by an auxiliary jet of fluid exiting the central nozzle 5, through the opening 6 in a jet or a sheet of folds or less. conical, depending on the position of the nozzles 4, the obliquity of the walls of the chamber 3 and the force of the jet of 5.



  The variant of the apparatus shown in FIG. 3 has a reaction chamber 7. of parabolic section. The purpose of this shape is to increase more and more the angle made. the flow of materials reacting with the axis of the apparatus as it. comes close to the opening 6 of the latter, as indicated by the line. mixed. In this way the reaction time inside the chamber 7 is increased and the reaction product is thrown in a flattened cone outside the chamber 7.



  In the form of the apparatus shown in FIG. 4, the nozzles are replaced by an annular slot 8, provided on the circumference of the reaction chamber. The fluid arrives through this slit 8 in a conical jet and mixes with the solid bodies which arrive through the tube 1 and which react with the fluid. A jet of fluid brought in. through the central nozzle 9 drives the final product through the orifice 10 (the chamber (the reaction. One can, if one wishes, animate the fluid of a movement. of rotation before. its exit from the slit annu air 8, by introducing it tangentially clans annular pipe 11, so i @ obtain clans chamber (the reaction a swirling sheet.



  In all the variants of the apparatus shown, the fluid can be heated before reaching the nozzles 4, 5, 9, for example, at the start (the operation by any known means, that is, for example, arcs or electrical resistances, either by passing it through supply tubes, placed in the immediate vicinity of the reaction chamber, or through channels in the walls of the reaction chamber, etc.



  The reaction apparatus can advantageously be arranged inside a closed body-shaped space (the vertical revolution, the base of which is closed by a cooled rotary hearth serving to collect the final powdery product. the top of this body of revolution is provided with openings through which the excess fluid escapes to be used again, the walls of refractory materials being. provided with channels through which the fluids can circulate before heading towards the reaction chamber Any other form of chamber can also be used.
