Abstract

Device making it possible to protect the water inside water towers against all atmospheric pollution of nuclear, biological and chemical origin. This device operates automatically and without energy merely by changing the water level in the water towers. It consists of a filter body (1) in which is placed an active-carbon filter (2) through which flows the air (7) automatically drawn in at the time of the water consumption. An air outlet (10) provided with a nonreturn delivery valve (11) operates automatically at the time when the water tower is being filled and by virtue of the nonreturn valve (8) situated at the filter outlet (2). For operation during a period when there is no pollution an aeration (13) operating freely is provided, but is equipped with a valve (15) for enabling the filtration to be stopped or brought into service.

Description

La présente invention concerne un dispositif pour protéger la potabilité de l'eau des châteaux d'eau, au moment de retombées Nucléaires, Biologiques,
Chimiques (N.B.C). The present invention relates to a device for protecting the potability of water from water towers, at the time of nuclear, biological fallout,
Chemical (NBC).

Les châteaux d'eau sont actuellement pourvus de simples évents qui ne sont équipés d'aucun système permettant l'anti-contamination de l'eau lors du passage d un nuage N.B.C. Une telle contamination interviendrait obligatoirement par les évents actuels, au moment de l'aspiration de l'air extérieur par tirage de 1 eau aux robinets par les utilisateurs. La vie de ces derniers serait compromise. Water towers are currently equipped with simple vents which are not equipped with any system allowing the anti-contamination of water during the passage of a cloud N.B.C. Such contamination would necessarily occur through current vents, when the outside air is sucked in by drawing water from the taps by users. Their lives would be compromised.

Le dispositif selon l'invention permet d'utiliser sans aucun risque liteau du robinet, et ce, malgré toute pollution atmosphérique. Il s'installe facilement, directement ou par réduction, sur les châteaux d'eau en lieu et place des évents actuels. En période de pollution, ce dispostif fonctionne automatiquement: à l'aspiration par tirage de l'eau par les utilisateurs; au refoulement, sans repassage dans le filtre spécial anti-N.B.C, par remplissage du château d'eau. Le dispositif comprend, pour éviter une consommation inutile du filtre pendant les périodes non polluées, un fonctionnement libre: aspiration-refoulement, avec clapet de fermeture à commande manuelle et ou électronique qui permet la mise en fonction ou l'arrêt de la filtration. The device according to the invention makes it possible to use the tap strip without any risk, despite any atmospheric pollution. It is easily installed, directly or by reduction, on water towers in place of current vents. In times of pollution, this device works automatically: on suction by drawing water by users; at the discharge, without ironing in the special anti-N.B.C filter, by filling the water tower. The device includes, to avoid unnecessary consumption of the filter during non-polluted periods, free operation: suction-discharge, with manually or electronically controlled shut-off valve which enables filtration to be switched on or off.

Les dessins annexés illustrent l'invention:
La figure 1 représente, en coupelongitudinale, le dispositif selon l'invention.The accompanying drawings illustrate the invention:
Figure 1 shows, in longitudinal section, the device according to the invention.

La figure 2 représente la vue de dessus.Figure 2 shows the top view.

En référence à ces dessins, le dispositif comporte:un corps de filtre (1) démontable pour permettre le remplacement de la cartouche filtrante (2) à charbon actif, un pot de condensation (3) au passage de la prise d'air (4) protégée à son entrée par un préfiltre (5) pour éviter toute pénétration d'insectes et autres. Un joint d'étanchéité (6) est prévu entre le corps du filtre (1) et la cartouche filtrante (2) pour assurer une filtration homogène et parfaite de l'air aspiré (7). Après passage dans le filtre (2) à charbon actif l'air aspiré (7) passe par un clapet anti-retour (8) avant de se rendre à l'intérieur du château d'eau (9). With reference to these drawings, the device comprises: a removable filter body (1) to allow the replacement of the filter cartridge (2) with activated carbon, a condensation pot (3) in the passage of the air intake (4 ) protected at its entry by a prefilter (5) to prevent penetration of insects and others. A seal (6) is provided between the filter body (1) and the filter cartridge (2) to ensure uniform and perfect filtration of the intake air (7). After passing through the activated carbon filter (2) the sucked air (7) passes through a non-return valve (8) before going inside the water tower (9).

Pour éviter une surpression à l'intérieur du château d'eau (9), le tropplein d'air s'évacue par la sortie (10) équipée d'un clapet de refoulement anti-retour (11), et d'un filtre (12) pour éviter les pénétrations d'insectes. To avoid overpressure inside the water tower (9), the overflow of air is evacuated through the outlet (10) equipped with a non-return discharge valve (11), and a filter (12) to avoid insect penetration.

Pour une ventilation normale en période de non contamination atmosphérique, une aération (13) à fonctionnement libre dans les deux sens: aspirationrefoulement, avec un filtre anti-insectes (14) est prévue. Cette aération (13) est équipée d'un clapet (15) à commande manuelle ou électrique permettant à volonté, la mise en fonction ou l'arrêt de la filtration. For normal ventilation in periods of non-atmospheric contamination, a ventilation (13) with free operation in both directions: suction suction, with an insect filter (14) is provided. This ventilation (13) is equipped with a valve (15) with manual or electric control allowing at will, the starting or stopping of the filtration.

Le dispositif d'aération protégée est installé directement en lieu et place (16), sans ou avec réduction, des évents classiques actuellement utilisés.  The protected ventilation device is installed directly in place of (16), with or without reduction, the conventional vents currently used.
