Abstract

A device for limiting consequences of a fire, in a room, including a reservoir including a vessel containing a liquid, the reservoir including one or more chambers in communication with a storage cell and one or more other chambers. The reservoir also includes at least a first overflow tank and at least a second overflow tank, both integral, placed on either side of the reservoir, each tank configured to receive the liquid when the liquid exceeds a predetermined given height in the vessel.

First claim

The invention claimed is:

1. A device for limiting consequences of a fire in a room in which the fire occurs, comprising:
a reservoir including a vessel containing a liquid, the reservoir including one or more chambers having a first opening in communication with the vessel and a second opening in communication with the room and one or more other chambers having a third opening in communication with the vessel of the reservoir and a fourth opening in communication with an area external to the room such that a flow path is formed between the room and the area external to the room;
the reservoir further including at least a first overflow tank and at least a second overflow tank, both integral, placed on either side of the vessel and separate from the flow path, each tank being separated from the vessel by a sidewall of the vessel and communicating with the vessel by way of openings formed in said side wall such that each tank being configured to receive the liquid when the liquid exceeds a predetermined given height in the vessel, wherein the room being a storage cell installed in a confinement enclosure the other chambers being in communication with the confinement enclosure and including one or more bubbling chambers being separated from the chambers by separation elements arranged orthogonally, at a bottom of the reservoir, the separation elements including wave-breaker devices, formed by plates fixed on bottom ends of the separation elements and which are oriented towards an inside of at least one bubbling chamber.

2. A device according to claim 1 , the bubbling chambers communicating with a retardation chamber situated in an upper part of the reservoir and communicating with the confinement enclosure by one or more openings.

3. A device according to claim 2 , the retardation chamber including a droplet catcher.

4. A device according to claim 1 , the bubbling chambers including a bubble splitting device.

5. A device according to claim 1 , the bubbling chambers including an anti-splatter device.

6. A device according to claim 5 , wherein the anti-splatter device is kept secured to the bubble splitting device by at least one basket and holding rods.

7. A device according to claim 1 , further comprising:
separation walls situated on either side of all the bubbling chambers and chambers, each of the separation walls being immersed in the liquid and being situated between a chamber and an inlet of one of the overflow tanks.

8. A device according to claim 7 , one of the walls comprising orifices in an upper part on a lateral face of a plate.

9. A device according to claim 1 , further comprising:
a system for regulating liquid levels in the reservoir, the regulation system including a circuit for supplying the reservoir with liquid.

10. A device for limiting consequences of a fire in a room in which the fire occurs, comprising:
a reservoir including a vessel containing a liquid, the reservoir including one or more chambers having a first opening in communication with the vessel and a second opening in communication with the room and one or more other chambers having a third opening in communication with the vessel of the reservoir and a fourth opening in communication with an area external to the room such that a flow path is formed between the room and the area external to the room;
the reservoir further including at least a first overflow tank and at least a second overflow tank, both integral, placed on either side of the reservoir and separate from the flow path, each tank configured to receive the liquid when the liquid exceeds a predetermined given height in the vessel, wherein the room being a storage cell installed in a confinement enclosure, the other chambers being in communication with the confinement enclosure and including one or more bubbling chambers; and channels configured to pour the liquid into the overflow tanks when its level reaches the predetermined given height.

11. A device for limiting consequences of a fire in a room in which the fire occurs, comprising:
a reservoir including a vessel containing a liquid, the reservoir including one or more chambers having a first opening in communication with the vessel and a second opening in communication with the room and one or more other chambers having a third opening in communication with the vessel of the reservoir and a fourth opening in communication with an area external to the room such that a flow path is formed between the room and the area external to the room;
the reservoir further including at least a first overflow tank and at least a second overflow tank, both integral, placed on either side of the reservoir and separate from the flow path, each tank configured to receive the liquid when the liquid exceeds a predetermined given height in the vessel;
a system for regulating liquid levels in the reservoir, the regulation system including a circuit for supplying the reservoir with liquid, the regulation system including a float valve, an opening of the float valve supplying liquid to the reservoir.

12. A device according to claim 11 , the supply of liquid being achieved by a forced supply independent of the regulation system.
