Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

INSTALLATION DE TRAITEMENT DE DECHETS HOSPITALIERS La présente invention concerne une installation de traitement de déchets hospitaliers qui fonctionne de manière autonome avec un apport d'énergie extérieure minimum.  The present invention relates to an installation for treating hospital waste which operates autonomously with a minimum supply of external energy.

Les déchets hospitaliers de type seringues, pansements usagés et autres, doivent être stérilisés dans un autoclave avant d'être broyés puis incinérés.  Hospital waste such as syringes, used dressings and others must be sterilized in an autoclave before being crushed and then incinerated.

Les installations de traitement de déchets hospitaliers existantes possèdent donc un dispositif de broyage des déchets ainsi qu'un autoclave permettant de stériliser ces déchets avant leur broyage.  Existing hospital waste treatment facilities therefore have a waste shredding device as well as an autoclave making it possible to sterilize this waste before shredding.

Les déchets broyés sont ensuite acheminés vers un incinérateur pour ordures ménagères classiques.  The crushed waste is then sent to an incinerator for conventional household waste.

Le transport de ces déchets à incinérer vers l'incinérateur augmente considérablement le coût de leur traitement.  Transporting this waste to be incinerated to the incinerator considerably increases the cost of its treatment.

Le but de la présente invention est de proposer une installation de traitement de déchets hospitaliers qui permet de réduire le coût de traitement de ces déchets.  The object of the present invention is to provide an installation for treating hospital waste which makes it possible to reduce the cost of treating this waste.

Ce but est atteint au moyen d'une installation de traitement de déchets hospitaliers qui comprend, de manière connue, un autoclave pour la stérilisation des déchets et un broyeur pour le broyage des déchets notamment stérilisés.  This object is achieved by means of a hospital waste treatment installation which comprises, in known manner, an autoclave for the sterilization of the waste and a grinder for the grinding of the waste, in particular sterilized.

Selon l'invention, de manière caractéristique, l'installation comprend également une chaudière d'incinération pour incinérer les déchets sortant du broyeur. According to the invention, typically, the installation also includes an incineration boiler for incinerating the waste leaving the crusher.

La chaudière étant sur le même site que l'autoclave et le broyeur, il est donc possible, par utilisation du dispositif de l'invention, de supprimer le coût du transport, et par la même, de réduire le coût global du traitement des déchets.  The boiler being on the same site as the autoclave and the shredder, it is therefore possible, by using the device of the invention, to eliminate the cost of transport, and by the same to reduce the overall cost of waste treatment .

L'énergie dégagée par la chaudière d'incinération est avantageusement recyclée pour alimenter l'autoclave et/ou un moteur à vapeur qui permet d'alimenter un alternateur qui fournit du courant électrique au broyeur.  The energy released by the incineration boiler is advantageously recycled to supply the autoclave and / or a steam engine which makes it possible to supply an alternator which supplies electric current to the crusher.

De préférence, la chaudière de l'installation de l'invention comprend un dispositif de traitement des fumées.  Preferably, the boiler of the installation of the invention comprises a device for treating smoke.

<Desc/Clms Page number 2> <Desc / Clms Page number 2>

En effet, les déchets hospitaliers sont susceptibles de dégager, lors de leur incinération, des fumées ou gaz plus ou moins toxiques ou polluants pour l'environnement.  In fact, hospital waste is likely to give off, when incinerated, more or less toxic fumes or gases or pollutants for the environment.

La vapeur, en sortant du moteur à vapeur, est avantageusement recyclée pour alimenter la chaudière d'incinération.  The steam, leaving the steam engine, is advantageously recycled to feed the incineration boiler.

La présente invention sera mieux comprise et ses avantages apparaîtront mieux à la lecture de la description qui suit et qui fait référence au dessin annexé qui représente un mode de réalisation particulier de l'installation de la présente invention et sur lequel : - la figure 1 représente un schéma de principe de l'installation de l'invention.  The present invention will be better understood and its advantages will appear better on reading the description which follows and which refers to the appended drawing which represents a particular embodiment of the installation of the present invention and in which: - Figure 1 represents a block diagram of the installation of the invention.

En référence à la figure 1, l'installation de l'invention comprend un autoclave 1, un broyeur 2 à déchets qui, dans l'exemple, sont déjà décontaminés et une chaudière 3. Les déchets hospitaliers contaminés notés D sont introduits dans l'autoclave 1, dans lequel ils sont stérilisés. Les déchets stérilisés D'sont ensuite broyés dans le broyeur à déchets décontaminés 2. Les déchets décontaminés et broyés D"sont ensuite introduits dans la chaudière d'incinération 3.  With reference to FIG. 1, the installation of the invention comprises an autoclave 1, a waste shredder 2 which, in the example, is already decontaminated and a boiler 3. The contaminated hospital waste denoted D is introduced into the autoclave 1, in which they are sterilized. The sterilized waste D 'is then ground in the decontaminated waste mill 2. The decontaminated and ground waste D "is then introduced into the incineration boiler 3.

La vapeur d'eau produite dans la chaudière d'incinération 3 est utilisée pour alimenter l'autoclave 1 et, si le débit de vapeur est assez important, pour alimenter un moteur à vapeur 4.  The steam produced in the incineration boiler 3 is used to feed the autoclave 1 and, if the steam flow is large enough, to feed a steam engine 4.

A cet effet, une partie de la vapeur produite est introduite dans l'autoclave 1 via une conduite de recyclage 3a et une autre partie de la vapeur est recyclée via une conduite de recyclage 3b vers le moteur à vapeur 4. Le moteur à vapeur 4 alimente un alternateur 5 qui fournit de l'électricité au broyeur à déchets décontaminés 2.  To this end, part of the steam produced is introduced into the autoclave 1 via a recycling line 3a and another part of the steam is recycled via a recycling line 3b to the steam engine 4. The steam engine 4 supplies an alternator 5 which supplies electricity to the decontaminated waste crusher 2.

La vapeur du moteur à vapeur 4 est condensée dans un condenseur 4a, puis passée sur une bâche alimentaire atmosphérique 6, en sorte de réalimenter la chaudière d'incinération 3 via la conduite 4b. La chaudière d'incinération 3 est également équipée d'un dispositif de traitement des fumées 7 qui permet de dépolluer les gaz produits par l'incinération des déchets hospitaliers.  The steam from the steam engine 4 is condensed in a condenser 4a, then passed over an atmospheric food tank 6, so as to replenish the incineration boiler 3 via the pipe 4b. The incineration boiler 3 is also equipped with a smoke treatment device 7 which makes it possible to clean up the gases produced by the incineration of hospital waste.

Il est possible, en utilisant l'installation de la présente invention, de traiter 10 tonnes par jour de déchets hospitaliers.  It is possible, using the installation of the present invention, to treat 10 tonnes per day of hospital waste.

<Desc/Clms Page number 3> <Desc / Clms Page number 3>

La chaudière d'incinération 3 fonctionne, dans l'exemple précis décrit, avec une pression de 6 bars et un flux de vapeur de 1500 kg/heure.  The incineration boiler 3 operates, in the precise example described, with a pressure of 6 bars and a steam flow of 1500 kg / hour.

600 kg/heure de la vapeur produite par la chaudière d'incinération 3 sont utilisés pour alimenter l'autoclave 1 alors que 800 kg de cette même vapeur sont utilisés pour alimenter le moteur à vapeur 4.  600 kg / hour of the steam produced by the incineration boiler 3 is used to feed the autoclave 1 while 800 kg of this same steam is used to feed the steam engine 4.

Dans l'exemple représenté, on a dissocié le broyeur de l'autoclave, mais le principe s'applique aux installations utilisant des broyeurs logés dans l'autoclave.  In the example shown, the shredder has been separated from the autoclave, but the principle applies to installations using shredders housed in the autoclave.

Sont également prévus des moyens d'alimentation du courant électrique délivré par le réseau de distribution. Means are also provided for supplying the electric current delivered by the distribution network.
