【発明の詳細な説明】
(産業上の利用分野)
この発明は、石油コンビナート等における消防自動車に
よる消防方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a firefighting system using fire engines in petroleum industrial complexes and the like.
(従来の技術)
石油コンビナート等の石油に関連するプラントにあって
は、泡消化液を放射する化学消防車、泡原液搬送車、高
所放水車がそれぞれ連携して消火活動をする。(Prior Art) In petroleum-related plants such as petroleum complexes, chemical fire engines that emit foam extinguishing liquid, foam concentrate transport vehicles, and high-altitude water cannon trucks work together to extinguish fires.
化学消防車には放水用のポンプと、泡原液槽と、泡原液
を水に注入する泡原液ポンプと、泡原液を水に混合する
泡原液混合器(以下混合器とする)とを積載している。The chemical fire truck is equipped with a water spray pump, a foam stock tank, a foam stock pump that injects the foam stock solution into water, and a foam stock mixer (hereinafter referred to as the mixer) that mixes the foam stock solution into water. ing.
そして、この化学消防車においては、放水用ポンプで吸

いる泡原液を混合器に注入して、放水用ポンプから吐出
する水に混合し、この泡混合消火液をノズルより放射す
る。そして泡原液槽内の泡原液不足分を次に挙げる泡原
液搬送車によって補給する。In this chemical fire engine, the water pump sucks water and discharges water, but at that time, the foam concentrate pump is injected into the mixer and mixed with the water discharged from the water discharge pump. This foam mixture extinguishing liquid is ejected from the nozzle. Then, the shortage of foam concentrate in the foam concentrate tank is replenished by the following foam concentrate transport vehicle.
泡原液搬送車は泡原液槽と泡原液ポンプとを積載し、こ
の泡原液ポンプによって自軍の泡原液を前記化学消防車
に移送する。The foam concentrate transport vehicle carries a foam concentrate tank and a foam concentrate pump, and the foam concentrate pump transfers the foam concentrate of the army to the chemical fire engine.
(発明が解決しようとする問題点)
石油コンビナートにおける実際の消防活動にあっては、
消火用の水源に消火栓を使うことが多い。(Problems to be solved by the invention) In actual firefighting activities at petroleum complexes,
Fire hydrants are often used as a water source for extinguishing fires.
この場合第2図のように、化学消防車aのポンプ吸水部
を消火栓すに連結する。この状態で化学渭防草aからは
放水管dによって泡原液を混入した泡消化液を放射する
ことができるが、次のような諸問題がある。In this case, as shown in Figure 2, the pump water suction part of the chemical fire engine a is connected to the fire hydrant. In this state, a foam extinguishing liquid mixed with a foam concentrate can be emitted from the chemical weed control a by the water discharge pipe d, but there are the following problems.
化学消防車にあっては、一般に放水用ポンプと泡原液用
ポンプは消防自動車のエンジンによって、それぞれギヤ
ーを介して運転する装置で、二つのポンプは並列に制御
されて、単独に制御する場合は一方をエンジンから切り
離して行うようになっている。In a chemical fire engine, the water spray pump and the foam concentrate pump are generally operated by the fire engine's engine through gears, and the two pumps are controlled in parallel, and when controlled independently, One side is separated from the engine.
そして積載している混合器は、放水圧力と泡原液の注入
圧力とが規定以内でないと、所定量の泡原液を水に注入
できず、消火性能が極端に低下する。The loaded mixer cannot inject a predetermined amount of foam concentrate into water unless the water discharge pressure and the injection pressure of the foam concentrate are within the specified range, and the fire extinguishing performance will be extremely reduced.
化学消防車の放水ポンプの吸水水頭が0〜7mと正常使
用状態では泡原液の水への混合は所定通りの濃度となる
が、ポンプ給水部にO〜約100mという十水頚値をも
つ消火栓を連結した場合には放水用ポンプの吸水圧力が
高いので、ポンプの吐出圧力は平水面から吸水する場合
に比べ、十水頭分だけ高くなるが、同一エンジンで放水
用のポンプと泡原液ポンプとを駆動しているため、十水
頭に比例して泡原液ポンプの吐出圧力は増加せず、泡原
液の混合器における混合比率は低下する。Under normal operating conditions, when the water suction head of the water pump of a chemical fire engine is 0 to 7 m, the foam concentrate is mixed into the water at the specified concentration. When the water discharge pump is connected, the suction pressure of the water discharge pump is high, so the pump discharge pressure is 10 water heads higher than when water is sucked from the flat water surface. , the discharge pressure of the foam concentrate pump does not increase in proportion to the ten-hydro head, and the mixing ratio of the foam concentrate in the mixer decreases.
したがって、化学消防車で消火栓を水源として所定濃度
の泡消化液を放射するため仁は、化学消防車aの放水ポ
ンプはエンジン駆動せず停止し、泡原液ポンプのみ駆動
制御し、混合器において泡原液を水に規定比率混入させ
る。Therefore, in order to emit foam extinguishing fluid of a predetermined concentration using a fire hydrant as a water source in a chemical fire engine, the water spray pump of chemical fire engine a should be stopped without driving the engine, only the foam stock pump should be driven and controlled, and the foam should be foamed in the mixer. Mix the stock solution into water at the specified ratio.
この状態では、化学消防車aにおける放水圧力は消火栓
の水圧力以下であるので、高所放水には使えない、その
ために放水管dに、さらに新たな消防ポンプ車eを連結
し、この消防ボン1車eのポンプによって放水圧力を上
げて消火活動しているのが実情である。In this state, the water discharge pressure in the chemical fire engine a is lower than the water pressure of the fire hydrant, so it cannot be used for discharging water to high places.Therefore, a new fire pump vehicle e is connected to the water discharge pipe d, and this fire hydrant is used. The reality is that firefighting efforts are being carried out by increasing the pressure of water discharged using one vehicle e's pump.
この発明は、上述する石油コンビナート火災における消
防方式において、ポンプ車を2台連結しなければならな
いという極めて不経済な現状に鑑み、新たな発送による
消防方式を提供するものである。In view of the extremely uneconomical current situation in which two pump trucks must be connected in the above-mentioned firefighting method for oil complex fires, this invention provides a new firefighting method using dispatch.

In the figure, a foam concentrate transport vehicle 1 is loaded with a foam concentrate pump and a foam concentrate mixer for mixing the foam concentrate into water, and a fire hydrant 2 is connected to the water intake part of a fire pump vehicle 3 via the foam concentrate mixer. A method characterized in that the foam concentrate loaded in the foam concentrate transport vehicle 1 is injected and mixed with water in a foam concentrate mixer using a foam concentrate pump, and the mixed foam extinguishing liquid is radiated by a fire pump vehicle 3. It is.

00m or more, but the foam concentrate pump can be operated independently and mixes the foam concentrate with water at a specified mixing ratio in the mixer.
The fire extinguishing fluid can be emitted by the fire pump truck 3 depending on the scale of the fire.
当然のことながら消防ポンプ車eはポンプをもつ化学消
防車、高所放水車を使うことができる。Naturally, fire pump truck e can be used as a chemical fire truck with a pump or a high-altitude water cannon truck.
消防ポンプ車3が従来通り混合器を積載する化学消防車
である場合は、この混合器を使用しないでよい。If the fire pump vehicle 3 is a conventional chemical fire engine that carries a mixer, this mixer may not be used.
またこの泡原液搬送には、他の泡原液搬送車が泡原液を
補給することは従来通りである。Further, in this foam stock solution transportation, other foam stock transport vehicles replenish the foam stock solution as usual.

できる。(Effects of the Invention) The firefighting system according to the present invention includes a foam mixer loaded on a conventional foam stock transport vehicle, and when mixing the foam stock solution into water coming from a fire hydrant in the foam stock transport vehicle,
By controlling the foam concentrate pump loaded on the foam concentrate transport vehicle to operate independently, the foam concentrate can be easily mixed into water at a predetermined ratio. A large amount of foam concentrate can also be used from the beginning using this carrier.
消防ポンプ車も従来のように2台連結する必要なく、極
めて合理的かつ経済的な消防方式である。There is no need to connect two fire pump trucks as in the past, making it an extremely rational and economical firefighting system.
泡原液を混入した水を吸水して放射する消防ポンプ車は

等多くの特長をもつものである。Fire pump trucks that absorb and release water mixed with foam concentrate do not use a foam concentrate mixer, so there is little pressure loss in water discharge pressure, and the water discharge pump is operated independently.
It has many features, such as being able to emit fire extinguishing foam without any restrictions on operation control, and being able to extinguish fires in expensive oil tanks in industrial complexes.
