Field of the Invention The present invention relates to a fire extinguisher, and more particularly to a fire extinguisher in which a powder fire extinguishing agent is directly added to the fire extinguishing water and the fire extinguishing water and the powder extinguishing agent are mixed in proportion.

れも多量の水が必要である。2. Description of the Related Art Conventionally, as a fire extinguishing device using fire-fighting water, there are a water extinguishing system using only water such as a so-called fire hydrant and a foam extinguishing device using a foam extinguishing agent. It is known that fire is extinguished by the cooling effect of air and the suffocation effect of foam, but both require large amounts of water.
【０００３】また完全に消火し再燃を防止させるために
はさらに多量に放水する必要があり、多量の水による水
損が発生したり火災現場が複数で離れている場合は消防
用水が不足するという問題点がある。Further, in order to completely extinguish a fire and prevent re-burning, it is necessary to discharge a large amount of water. If a large amount of water causes water damage or if fire sites are located at a plurality of places, fire water is insufficient. There is a problem.
【０００４】粉末消火薬剤には再燃抑制作用があること
が知られており、粉末消火薬剤水溶液は可燃物，特に一
般火災の対象物である建築物の木材等に放水すると木材
に含浸し熱によりガラス状皮膜となり表面を覆うために
火炎を防ぎ再燃抑制効果が生じる。It is known that a powder fire extinguishing agent has an effect of suppressing re-flammability. When an aqueous solution of a powder fire extinguishing agent is discharged to a combustible material, particularly to a building fire, which is a target of general fire, it impregnates the wood and generates heat. Since it becomes a glassy film and covers the surface, a flame is prevented and a reburn suppression effect is produced.
【０００５】粉末消火薬剤水溶液を使用した消火装置と
しては、再燃抑制剤である粉末消火薬剤水溶液を消火器
容器に充填して放射する消火器は存在するが、固定消火
設備，化学消防自動車の消火装置等の大規模な消火装置
には利用されていない。As a fire extinguisher using an aqueous solution of a powder fire extinguishing agent, there is a fire extinguisher that irradiates a fire extinguisher container by filling an aqueous solution of a powder extinguishing agent, which is a reburn suppressant, with a fire extinguisher. It is not used for large-scale fire extinguishers such as equipment.
【０００６】これは消火器の場合は使用水溶液量が少な
いために事前に粉末消火薬剤を水溶液にしてもその貯蔵
や運搬等に労を要しないが、大規模な消火装置の場合は
水溶液量が多量となり貯蔵や運搬等の取り扱いも不便で
あり、また維持管理も繁雑となるという問題点がある。[0006] In the case of a fire extinguisher, the amount of aqueous solution used is small. Therefore, even if a powder fire extinguishing agent is used in advance as an aqueous solution, no labor is required for storing and transporting the solution. There is a problem that the amount is large, handling such as storage and transportation is inconvenient, and maintenance is complicated.

たり溶解することができなくなるという問題点もある。Further, it is very difficult to mix and dissolve the powder fire extinguishing agent at a fire site, and it is very difficult to maintain and adjust the mixing ratio. In particular, when the powder fire extinguishing agent is directly injected into the pressurized fire fighting water such as a fire hydrant, the powder extinguishing agent is injected. There is also a problem that the powder fire extinguishing agent absorbs moisture in the portion and solidifies into a gel mass, so that it cannot be transferred or dissolved.

火災の再燃抑制効果を十分に生じさせることができる。That is, the powder fire extinguishing agent, which is a fire relapse inhibitor, is directly mixed into the fire extinguishing water and is proportionally dissolved in accordance with the flow rate of the fire extinguishing water, so that the powder fire extinguishing agent can be discharged at a constant concentration. It is possible to sufficiently prevent the re-ignition of the fire by preventing the ignition of the fire caused by the fire or jumping fire.
