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.
