Description

  

      Installation    pour     l'épuration    des gaz d'échappement d'un moteur    L'invention a pour objet une installation  pour l'épuration des gaz d'échappement d'un  moteur à combustion interne, comprenant au  moins un récipient contenant une matière  épurante disposée sur un support. Cette ins  tallation se distingue des installations connues  par le fait que le récipient est     relié    au mo  teur de façon que les gaz d'échappement du  moteur soient obligés de traverser la matière  épurante dans le sens de haut en bas, afin  d'empêcher     l'entraînement    de cette matière  par les gaz d'échappement.  



  Le     dessin    annexé représente, schématique  ment et à titre d'exemple, une forme d'exécu  tion de l'objet de l'invention.  



  La     fig.    1 est une vue en élévation, avec  parties en coupe, de cette forme d'exécution,  laquelle comprend deux filtres successifs dis  posés sur une conduite d'échappement d'un  moteur.  



  La     fig.    2 représente une variante d'exé  cution d'un filtre.  



  A la     fig.    1, 1 représente un moteur à com  bustion interne présentant un tuyau d'échap  pement 2 dans lequel se trouve un clapet mo  bile 3. Ce dernier peut occuper deux positions,  dont une permet aux gaz d'échappement de  passer dans une conduite 4 présentant un       pôt    d'échappement de type connu et non re  présenté ; l'autre position du clapet 3 qui est    représentée au dessin oblige les gaz à passer  dans une conduite 5 d'une installation d'épu  ration. Cette conduite 5 aboutit dans un réci  pient 6 par un orifice d'amenée des gaz 7 qui  se trouve à la partie supérieure de ce dernier.  Un support 8 ajouré s'étend sur toute la sec  tion horizontale du récipient 6 et comprend  des cloisons sensiblement verticales 9.

   Ce sup  port est recouvert d'une couche de matière  épurante 10, constituée par du peroxyde de  fer     (Fe2    03), qui a pour but d'absorber le  soufre et différents goudrons contenus dans  les gaz d'échappement. En face de l'orifice 7  d'amenée des gaz dans le récipient 6 se trouve  un     déflecteur    11 pour empêcher ceux-ci     d7ar-          river    à     pleine    vitesse sur la matière épurante.  Ce     déflecteur    11 constitue un dispositif pour  répartir les gaz sur toute la surface de la ma  tière épurante.

   Après       avoir    traversé cette der  nière, les gaz quittent le récipient 6 par un  orifice 12 d'évacuation, qui se trouve à la  partie inférieure de ce dernier. Les gaz passent  ensuite dans une conduite 13 et débouchent  par un orifice 7a dans un récipient 6a en tous  points semblable au récipient 6 décrit ci-des  sus. Cependant, le support 8a du récipient da  est recouvert d'une couche de charbon     actif     14 destiné à absorber l'oxyde de carbone con  tenu dans les gaz d'échappement. Après avoir  traversé la couche 14, ces derniers peuvent  s'échapper à l'extérieur par une conduite 15.

        L'installation représentée à la     fig.    1 est  spécialement destinée à l'épuration des gaz  d'échappement d'un moteur se trouvant sur un  véhicule, et c'est pour cette raison que les cloi  sons verticales 9 sont prévues, afin d'empê  cher de grands déplacements de la matière  épurante lorsque le véhicule se trouve sur une  pente.  



  La     fig.    2 représente 'une     variante    d'un ré  cipient 6 comprenant une herse 16 dont les  pointes sont destinées à brasser la matière  épurante 10. Cette herse, qui     constitue    un dis  positif de brassage, est suspendue à la partie  supérieure du récipient 6 par des biellettes 17,  de sorte que les secousses du véhicule peuvent  provoquer des mouvements de la herse par  rapport à la matière épurante et brasser ainsi  cette dernière. De plus, la herse 16 comprend  un organe 18 permettant son     actionnement    de  l'extérieur du récipient.

   Il arrive, en effet,  que les différents corps gras contenus dans  les gaz d'échappement forment une croûte à  la surface de la matière épurante, cette croûte  étant assez résistante pour empêcher les mou  vements de la herse provoqués par les secous  ses du véhicule. On peut alors briser cette  croûte en actionnant l'organe 18. Dans cette  forme d'exécution, on n'a pas prévu de cloi  son verticale 9, car la herse 1,6 empêche, dans  une certaine mesure, les déplacements laté  raux de la matière épurante 10, mais     il    est  bien entendu que des cloisons verticales pour  raient être ajoutées si on le désire.  



  Il est bien entendu que les deux réci  pients 6 et 6a successifs pourraient être mon  tés en série dans un ordre quelconque et qu'on  pourrait prévoir plus de deux récipients for  mant filtre et contenant chacun une matière  épurante différente.



      Installation for the purification of the exhaust gases of an engine The subject of the invention is an installation for the purification of the exhaust gases of an internal combustion engine, comprising at least one receptacle containing a purifying material placed on a support. This installation differs from known installations in that the receptacle is connected to the engine so that the exhaust gases from the engine are forced to pass through the purifying material from the top to the bottom, in order to prevent the entrainment of this material by the exhaust gases.



  The appended drawing represents, schematically and by way of example, one embodiment of the object of the invention.



  Fig. 1 is an elevational view, with parts in section, of this embodiment, which comprises two successive filters arranged on an exhaust pipe of an engine.



  Fig. 2 represents an alternative embodiment of a filter.



  In fig. 1, 1 shows an internal combustion engine having an exhaust pipe 2 in which there is a movable valve 3. The latter can occupy two positions, one of which allows the exhaust gases to pass through a pipe 4 having an exhaust pipe of a known type and not shown; the other position of the valve 3 which is shown in the drawing forces the gases to pass through a pipe 5 of a purification installation. This pipe 5 ends in a receptacle 6 via a gas supply orifice 7 which is located at the upper part of the latter. A perforated support 8 extends over the entire horizontal section of the container 6 and comprises substantially vertical partitions 9.

   This support is covered with a layer of purifying material 10, consisting of iron peroxide (Fe2 03), the purpose of which is to absorb the sulfur and various tars contained in the exhaust gases. Opposite the orifice 7 for supplying the gases into the receptacle 6 is a deflector 11 to prevent the latter from arriving at full speed on the purifying material. This deflector 11 constitutes a device for distributing the gases over the entire surface of the purifying material.

   After passing through the latter, the gases leave the receptacle 6 through an evacuation orifice 12, which is located at the lower part of the latter. The gases then pass through a pipe 13 and open through an orifice 7a into a container 6a in all respects similar to the container 6 described above. However, the support 8a of the container da is covered with a layer of activated carbon 14 intended to absorb the carbon monoxide contained in the exhaust gases. After passing through the layer 14, the latter can escape to the outside through a pipe 15.

        The installation shown in fig. 1 is specially intended for the purification of the exhaust gases of an engine located on a vehicle, and it is for this reason that the vertical partitions 9 are provided, in order to prevent large displacements of the material clean when the vehicle is on a slope.



  Fig. 2 shows a variant of a receptacle 6 comprising a harrow 16, the points of which are intended to stir the purifying material 10. This harrow, which constitutes a stirring device, is suspended from the upper part of the receptacle 6 by connecting rods 17, so that the shaking of the vehicle can cause movements of the harrow relative to the purifying material and thus stir the latter. In addition, the harrow 16 comprises a member 18 allowing its actuation from outside the container.

   It happens, in fact, that the various fatty substances contained in the exhaust gases form a crust on the surface of the purifying material, this crust being strong enough to prevent the movements of the harrow caused by the shaking of the vehicle. This crust can then be broken by actuating the member 18. In this embodiment, there is no provision for a vertical wall 9, because the harrow 1.6 prevents, to a certain extent, lateral movements of the purifying material 10, but it is understood that vertical partitions could be added if desired.



  It is understood that the two successive receptacles 6 and 6a could be assembled in series in any order and that more than two receptacles forming a filter could be provided, each containing a different purifying material.
