【考案の詳細な説明】
本考案は、可燃液状物貯留タンクの周囲に形成
した漏洩液状物貯留空間に発泡消火剤を供給する
消火装置に関する。[Detailed Description of the Invention] The present invention relates to a fire extinguishing device that supplies a fire extinguishing foam to a leaked liquid storage space formed around a combustible liquid storage tank.
従来、漏洩液状物が火災を生じてもその熱によ
つて損傷されないように、混合器を漏洩液状物貯
留空間から遠くに離して設置していた。 Conventionally, the mixer has been installed far away from the leaked liquid storage space so that it will not be damaged by the heat even if the leaked liquid causes a fire.
しかし、混合器から漏洩液状物に発泡消火剤を
供給するに、発泡消火剤が長いパイプを通過する
ために比較的長時間を要し、殊に液化天然ガスや
液化石油ガスのように気化しやすく、かつ引火性
の強い可燃液状物を対象とする場合、火災が発生
しやすく、また、火災が大きくなりやすいために
消火が困難になる欠点があつた。 However, supplying foam fire extinguishing agent from a mixer to a leaking liquid requires a relatively long time as the foam passes through a long pipe, especially when it is vaporized such as liquefied natural gas or liquefied petroleum gas. When using combustible liquid materials that are easily flammable and highly flammable, there are disadvantages in that fires tend to occur, and the fires tend to grow larger, making it difficult to extinguish them.
本考案の目的は、タンクから可燃液状物が漏洩
した時に漏洩液状物貯留空間への発泡消火剤供給
を迅速に行えるようにして、火災発生防止を効果
的に行え、かつ、たとえ火災が発生しても迅速に
消火できるようにする点にある。 The purpose of this invention is to make it possible to quickly supply fire extinguishing agent to the leaked liquid storage space when flammable liquid leaks from a tank, thereby effectively preventing the occurrence of a fire, and even if a fire occurs, The aim is to extinguish the fire quickly.

構造体を設けたことにあり、その作用効果は次の
通りである。 The characteristic configuration of the present invention is that a mixer connected to pipes for separately supplying a plurality of liquids for producing fire extinguishing foam, and a valve mechanism attached to each of the pipes are arranged adjacent to a leakage liquid storage space. With,
A heat insulating structure is provided to protect the mixer and valve mechanism from radiant heat caused by a fire in the leaked liquid storage space, and its effects are as follows.
つまり、断熱構造体によつて火災から保護でき
るようにして混合器及び弁機構を漏洩液状物貯留
空間に隣接配置してあるから、発泡消火剤を漏洩
液状物に対して極めて迅速に供給でき、漏洩液状
物の火災発生を効果的に防止できると共に、たと
え漏洩液状物が火災を生じても、火災を大きくせ
ずに効果的に消火できる。 In other words, since the mixer and the valve mechanism are arranged adjacent to the leaked liquid storage space so as to be protected from fire by the heat insulating structure, the foam extinguishing agent can be supplied to the leaked liquid very quickly. To effectively prevent a fire from occurring due to leaked liquid, and even if a fire occurs due to leaked liquid, the fire can be extinguished effectively without increasing the size of the fire.
また、断熱構造体によつて混合器及び弁機構を
雨等から保護できるから、混合器や弁機構の経年
劣化を抑制でき、長期にわたつて信頼性の高い状
態で火災防止及び消火を行える。 Further, since the mixer and the valve mechanism can be protected from rain etc. by the heat insulating structure, deterioration of the mixer and the valve mechanism over time can be suppressed, and fire prevention and extinguishing can be performed in a highly reliable state over a long period of time.
その結果、タンク内の可燃液状物がたとえ液化
天然ガスや液化石油ガス等のように引火性の強い
ものであつても、可燃液状物の漏洩に伴う火災を
効果的に防止でき、もし火災が発生したとして
も、迅速かつ確実に消火でき、安全性向上を十分
に図れるようになつた。 As a result, even if the flammable liquid in the tank is highly flammable, such as liquefied natural gas or liquefied petroleum gas, it is possible to effectively prevent a fire caused by a leak of flammable liquid, and if a fire occurs, Even if a fire does occur, it can be extinguished quickly and reliably, making it possible to sufficiently improve safety.
