  • Patent number: 6173790
    Abstract: A process and a device for atomization of a liquid extinguishing medium, in which the liquid extinguishing medium and a liquid inert gas are mixed in a mixing unit to form a liquid extinguishing medium mixture. The mixture is conveyed through a conduit to a distributing device such as extinguishing nozzles. As the mixture exits the distributing device the mixture is atomized, forming an aerosol spray for extinguishing a fire within an extinguishing area defined by the aerosol spray. A detector arranged in the extinguishing area for detection of parameters relating to extinguishing of the fire is connected to an evaluation device which in turn is connected to a control valve. The control valve regulates the quantity of liquid inert gas supplied to the mixing unit.

  • Patent number: 6044910
    Abstract: A device for introducing CO.sub.2 into a preferably liquid extinguishing medium includes a housing (1) with a feed line (2) for extinguishing fluid, a feed pipe (4), provided with a metering valve (3), for CO.sub.2, as well as an outlet line (5). The housing (1) is aligned with its longitudinal axis vertical; the feed line (2) for extinguishing fluid is connected to the housing at the lower end thereof; the outlet line (5) branches off from the upper end of the housing. The CO.sub.2 feed pipe (4) opens into the housing from above, extends as far as the lower end thereof and is provided at the pipe end with injection fluid (6). The CO.sub.2 is directed in the feed pipe in the opposite flow direction to the extinguishing fluid; the length of the feed pipe between the metering valve (3) and injection fluid (6) is dimensioned such that during operation with the metering valve (3) closed a gas cushion (7) forms on its downstream side.
