Definitions

  • the present invention relates to a fire extinguisher apparatus in use for extinguishing a fire. More particularly, the invention relates to a fire extinguisher apparatus of the auxiliary pressure type, wherein a cartridge containing pressurized gas is used for pressurizing the fire extinguisher.
  • An extinguisher contains an extinguishing agent that can be thrown onto a fire by the action of internal pressure.
  • This pressure can be provided by a permanent pre-press (the permanent pressure system) or by the release of an auxiliary gas (very often carbon dioxide) contained in a cartridge (the auxiliary pressure system).
  • the extinguisher is provided with a gas cartridge, generally CO 2, totally hermetic.
  • a gas cartridge generally CO 2
  • the fact of enclosing the propellant in a cartridge makes it possible to avoid leaks, but it is necessary to "strike” the cartridge (to pierce it) to be able to use it: the gas is then released from the cartridge and fills the body of the extinguisher containing the extinguishing agent.
  • the extinguisher In an auxiliary pressure system the extinguisher is not under pressure before use, so there is no risk of leakage in handling and storage.
  • the pressure contained in the cartridge is discharged into the body of the apparatus by perforation thereof.
  • the pressure then relaxes in the body of the apparatus to stabilize at about 15 bar. It is a guarantee of having the necessary pressure for optimum operation even after long storage.
  • the apparatus does not require as control manometer is no pressure inside of the bottle before percussion of the cartridge CO2. This technique is therefore ideal for the private market. It is also better suited to large-scale distribution and automotive applications where the risks of shocks and vibrations exist, which could in the case of the permanent pressure system have unfortunate consequences (breakage of the valve for example and leakage of powder).
  • auxiliary pressure type fire extinguishers known in the prior art is the fact that the homogenization of the gas and the extinguishing agent, once the gas is released from the cartridge and fills the body containing the extinguishing agent, is not always optimal. This can result in leftover extinguishing agent (powders) piling up in the fire extinguisher. The capacity of the fire extinguisher is thus reduced.
  • the object of the present invention is to improve the operation of a fire extinguisher apparatus, preferably an auxiliary pressure extinguisher for extinguishing agent of the "dry powder" type. More particularly, the invention aims to improve the operation of a fire extinguisher by optimizing the drying out of the extinguishing powder and the homogenization of the propellant and the powder.
  • the present invention also aims to provide an extinguisher apparatus in which the pressurization of the extinguisher is improved, and in particular accelerated.
  • the invention relates to a fire extinguisher apparatus, and in particular a fire extinguisher of the auxiliary pressure type.
  • the apparatus is characterized in that the end (s) of the at least one ejection channel (s) are housed in one or more cells formed by a deflector (s). ) located on the outer wall of said tube.
  • the apparatus is characterized in that the cartridge is essentially cylindrical and provided with a neck containing a cover provided for the perforation of the cartridge.
  • the apparatus is characterized in that cartridge is placed upside down in said central tube with its neck and its lid oriented towards the base of the body.
  • the apparatus is characterized in that the central tube is divided into an upper part and a lower part whose outer diameter is smaller than the outer diameter of the upper part of said tube.
  • the cartridge is mounted within the upper portion of said central tube, and the outer diameter of said cartridge is smaller than the inner diameter of said upper portion of the tube, so that a circumferential gap is created between said cartridge and the upper part of said tube.
  • said apparatus is characterized in that said lower centering device is provided in the upper part of said central tube at the neck of said cartridge.
  • the apparatus is characterized in that the one or more propellant gas ejection channels are provided at a height between the lower half height and the lower third quarter of the internal height of said body.
  • said ejection channel or channels are directed downwards and pass from the inside of the central tube to the core of the powder mass.
  • the apparatus according to the invention is preferably characterized in that said upper centralizer is composed of a cylindrical chamber at the base of which is mounted a holding ring containing openings for the passage of the extinguishing agent.
  • the invention relates to a fire extinguishing method in which preferably an extinguisher apparatus according to the invention is implemented.
  • the process is characterized in that the propellant is expelled at the outlet of the cartridge into the extinguishing agent through one or more ejection channels passing through the transverse wall of the central tube and directed downwards, the gas being propelled at an angle of at least 30 ° with respect to the ejection direction by means of one or more deflectors.
  • the method is characterized in that the propellant gas is expelled at the outlet of the cartridge at a height between the lower half height and the lower third quarter of the internal height of the body of the fire extinguisher apparatus.
  • the mixture of the propellant and extinguishing agent enters the interior of the central tube through the base of said tube and is transported inside the central tube along said cartridge towards the extinguisher head.
  • the expulsion of the propellant and the penetration into the central tube of the mixture of propellant and extinguishing agent are preferably spatially separated.
  • the pressurization of said extinguisher and the emptying of the extinguishing agent are carried out simultaneously. According to another embodiment, the pressurization of said extinguisher and the emptying of the extinguishing agent are carried out consecutively.
  • the operating principle of this device is as follows.
  • the propellant gas contained in the cartridge is released precipitately into the body (the bottle) of the extinguisher and directly into the mass of the extinguishing powder by one or more ejection channels placed suitably in one or more cells formed by one or more deflectors along the central tube.
  • This action aims to detach the powder contained in the bottle to form a homogeneous mixture of propellant and powder.
  • the opening of the fire extinguisher head (the shut-off valve) then allows the evacuation of the extinguishing powder.
  • the propellant is expelled at the outlet of the cartridge directly into the mass of extinguishing powder.
  • the propulsion of gas into the powder can be carried out by one or more ejection channels. Propulsion of the gas into the powder can be carried out at different levels as long as it is in the powder mass.
  • the ejection channel or channels are preferably provided at a height between the lower half height and the lower third quarter of the internal height of the body of the fire extinguisher.
  • the ejection channel (s) are also preferably directed downwards and pass from the inside of the central tube to the core of the powder mass.
  • the end of the ejection channel or channels are housed in one or more cells formed by one or more baffles located on the outer wall of the central tube.
  • the present invention therefore makes it possible to considerably reduce the charge of the powder residue after emptying it at once, in accordance with the requirements of the EN3 standard (applicable to "portable fire extinguishers") for which the residual charge for this type of powder is currently not more than 10% of the powder mass initially contained in the fire extinguisher.
  • the propellant gas enters directly into the extinguishing powder at the outlet of the cartridge, while the mixture of the propellant and the extinguishing agent enters the central tube at the lower end of said tube, and is transported inside the central tube along said cartridge towards the extinguisher head.
  • the output of the propellant gas from the cartridge and the entry of the mixture of gas and powder are therefore carried out at different levels.
  • the propellant must not flow through the central tube before being discharged into the mass of extinguishing powder. This results in a saving of time: the gas is released more quickly in the extinguishing powder, homogenization of the propellant and the powder is accelerated, and the pressurization of the fire extinguisher is more quickly obtained.
  • An auxiliary pressure type fire extinguisher generally consists of a body, preferably a metal cylinder, a valve (also known as a fire extinguisher or stopcock), a central tube and a cartridge. gas.
  • Portable fire extinguishers are equipped with a handle to carry the fire extinguisher and to strike the cartridge.
  • the terms "extinguisher” or “fire extinguisher” are used as synonyms.
  • the propulsion of the gas contained in the cartridge and the control of the apparatus have been improved by introducing operating elements at the outlet of the cartridge and the head of the extinguisher.
  • the apparatus has been improved so that the ejection of the propellant gas into the bottle is confronted by means of one or more ejectors housed in one or more cells formed by one or more deflectors.
  • This or these baffles are used to direct the propellant in the powder mass and allow better homogenization of the gas and extinguishing agent and thus a better de-packing thereof.
