Definitions

  • the invention relates to a method for dispensing an extinguishing agent from an extinguishing agent container of a fire extinguisher with the aid of a compressed gas escaping from a pressure container.
  • the invention further relates to a fire extinguisher consisting of a pressure container for compressed gas and an extinguishing agent container from which the extinguishing agent can be expelled by the compressed gas and can be sprayed in finely divided form from a spray nozzle under the pressure of the compressed gas.
  • the invention particularly relates to manual fire extinguishers.
  • fire extinguishers have an extinguishing agent container which is designed to be pressure-resistant (as a "pressure container” according to the Pressure Container Ordinance) and in which the highest possible pressure with a compressed gas is formed to expel the extinguishing agent.
  • the compressed gas can be in the extinguishing agent container in the permanent state. This type is called "permanent pressure extinguisher".
  • the compressed gas is in its own pressure container and only reaches the pressure-resistant extinguishing agent container in use, in order to form the pressure cushion there with which the extinguishing agent, which can be powdery or liquid , is expelled via a spray nozzle.
  • Such fire extinguishers are called “charging extinguishers” because the extinguishing agent container is only “charged” with the pressure when it is used.
  • fire extinguishers should generally be portable and that a high compressive strength leads to a high weight of the extinguishing agent container. In order to ensure the portability of the fire extinguisher, a maximum total weight must be observed.
  • An advantageous increase in the pressure of the pressurized gas for spraying the extinguishing agent which leads to an increase in the weight of the extinguishing agent container, must be compensated for by reducing the weight of the extinguishing agent, that is to say by reducing the amount of extinguishing agent.
  • a common compromise for conventional fire extinguishers is an operating pressure of 17 bar. The degree of distribution that can be achieved for liquid and solid extinguishing agents is naturally limited.
  • a method for dispensing an extinguishing agent from an extinguishing agent container of a fire extinguisher using a pressurized gas escaping from a pressure container is characterized in that the pressurized gas is directed past an opening of the extinguishing agent container in such a way that the extinguishing agent comes out of the container is sucked out and sprayed with the compressed gas.

  • the compressed gas is thus stored in a pressure container, as in the design of the charging extinguisher, but the compressed gas is not introduced into the extinguishing agent container. Rather, with the aid of the compressed gas, a negative pressure is generated at the opening of the extinguishing agent container, so that the extinguishing agent is sucked out of the extinguishing agent container and sprayed with the compressed gas via a spray nozzle. Accordingly, it is possible to design the extinguishing agent container with a low compressive strength, so that the extinguishing agent container is made of a simple material, e.g. Recycled plastic with relatively thin walls can exist.
  • a relatively small pressure vessel is required for the compressed gas, which can easily be designed for pressures of 150 to 300 bar. Accordingly, the extinguishing agent can also be sprayed at this high pressure, as a result of which droplet sizes of 0.01 to 0.1 mm can be achieved, for example, with liquid extinguishing agents which are at least 10 times smaller than droplet sizes achieved conventionally with operating pressures of 17 bar .
  • the extinguishing agent can be transported into the area of the opening with the aid of at least one suction line, but also, for example, by atomizing a liquid extinguishing agent by mechanical or pressure swirling (for example with the aid of a portion of the compressed gas), so that in the area of the opening there is always enough extinguishing agent available that is sucked in and gets into the stream of compressed gas.

Abstract

Pour réduire le poids d'un extincteur (1, 1', 1', 1''') et augmenter sa capacité d'extinction, l'agent d'extinction (15) est extrait du réservoir (4, 4', 4', 4''') le contenant, à l'aide d'un gaz comprimé situé dans un réservoir sous pression (6). Le gaz comprimé est guidé de manière à passer devant un orifice (13) du réservoir (4, 4', 4', 4''') contenant l'agent d'extinction, de sorte que ledit agent (15) soit aspiré hors du réservoir (4, 4', 4', 4''') le contenant, et soit pulvérisé conjointement avec le gaz comprimé. Dans ce type de structure, le réservoir (4, 4', 4', 4''') contenant l'agent d'extinction n'est pas exposé à la surpression du gaz comprimé régnant dans le réservoir sous pression (6). Ce procédé permet d'obtenir un réservoir (4, 4', 4', 4''') pour l'agent d'extinction de l'extincteur (1), de poids réduit et pouvant contenir un volume plus important d'agent d'extinction (15). Le gaz comprimé peut en outre être maintenu à très haute pression (⊃ 150 bar).
