Description
本発明は、消火性能と延焼防止性能を併せ持つ消火薬剤及び消火設備に関する。 The present invention relates to a fire extinguishing agent and fire extinguishing equipment having both fire extinguishing performance and fire spread prevention performance.
各種の消火設備で使用されている消火薬剤として、水に浸潤剤を添加した水系消火薬剤や機械泡消火薬剤が知られている。水系消火薬剤と機械泡消火薬剤には、それぞれ一長一短があり、水系消火薬剤は消火性能に優れるものの、防火対象物にかかった薬剤は直ちに他方へ流れ落ちてしまうため、延焼防止性能に難があり、一方、機械泡消火薬剤は防火対象物に付着して容易に脱落しないため延焼防止性能に優れるものの、立体物などの隙間には入り込み難いため、消火性能に難がある。このため、消火設備では、防火対象物に応じて選択して使用している（例えば、特許文献１、２参照）。 As fire extinguishing agents used in various fire extinguishing facilities, water-based fire extinguishing agents obtained by adding a wetting agent to water and mechanical foam extinguishing agents are known. Water-based fire extinguishing chemicals and mechanical foam fire-extinguishing chemicals have their merits and demerits. Although water-based fire-extinguishing chemicals are excellent in fire extinguishing performance, chemicals applied to the fire prevention object immediately flow down to the other side, so there is a difficulty in preventing fire spread. On the other hand, although a mechanical foam fire-extinguishing agent adheres to a fire prevention object and does not easily fall off and has excellent fire spread prevention performance, it is difficult to enter a space such as a three-dimensional object, so fire fighting performance is difficult. For this reason, in fire extinguishing equipment, it selects and uses it according to a fire prevention object (for example, refer to patent documents 1 and 2).
上記のように、水系消火薬剤と機械泡消火薬剤にはそれぞれ一長一短があり、消火設備では、防火対象物に応じて選択して使用されているのが実情であるが、消火性能と延焼防止性能を併せ持つ消火薬剤が望まれる。
本発明者等は、このような要望に応えるべく試験研究を重ねた結果、水系消火薬剤に発泡成分を添加することに着目し、本発明を完成するに至った。
As mentioned above, water-based fire extinguishing agents and mechanical foam fire-extinguishing agents have their merits and demerits, and in fire extinguishing equipment, it is the actual situation that they are selected and used according to the fire prevention object, but fire extinguishing performance and fire spread prevention performance A fire extinguishing agent having both of these is desired.
As a result of repeated test and research to meet such demands, the present inventors have focused on adding a foaming component to an aqueous fire extinguishing agent, and have completed the present invention.

また、消火性能と延焼防止性能を併せ持つことにより、消火効果と延焼防止効果を得るのに必要な消火薬剤の量を従来の消火薬剤に比べ少なくすることができ、コストの削減を図ることができる。
According to the fire-extinguishing agent according to claim 1, since the foaming component is added to the water-based fire-extinguishing agent in which an infiltrant is added to water, a part of the fire-extinguishing agent is foamed by passing through a foaming device when discharged from the fire-extinguishing equipment. The fire extinguishing agent that is released in a state of being applied to the object to be fired is applied to the object to be fired. It is possible to have a fire spread prevention performance by preventing the object from coming off from the object immediately and maintaining an adhesion state for a certain period of time.
In addition, by having both fire extinguishing performance and fire spread prevention performance, it is possible to reduce the amount of fire extinguishing agent necessary to obtain the fire extinguishing effect and fire spread preventing effect compared to conventional fire extinguishing agents, and to reduce costs. .

請求項３に記載の泡消火設備によれば、泡を含んだ消火薬剤を放出するので、放出された消火薬剤は、消火性能と延焼防止性能を併せ持ち、消火効果と延焼防止効果を発揮することができ、これにより、消火効果と延焼防止効果を得るのに必要な消火薬剤の量が少なくなるので、結果として、設備がコンパクトなものとなり、設備コストの削減、占有空間の削減が可能となる。 According to the foam fire-extinguishing equipment according to claim 3, since the fire-extinguishing agent containing foam is released, the released fire-extinguishing agent has both the fire extinguishing performance and the fire spread prevention performance, and exhibits the fire extinguishing effect and the fire spread preventing effect. As a result, the amount of fire extinguishing agent required to obtain a fire-extinguishing effect and a fire spread-preventing effect is reduced. As a result, the equipment becomes compact, and the equipment cost and the occupied space can be reduced. .
以下、本発明に係る消火薬剤の実施の形態の一例を詳細に説明する。
本例の消火薬剤は、水に浸潤剤を添加した水系消火薬剤に、発泡成分を添加したものからなる。水に浸潤剤を添加した水系消火薬剤にあっては、公知の水系消火薬剤が使用されるものであって、本例では燃焼反応の負触媒効果をもたらす成分としてリン酸アンモニウムが使用されている。本例で使用される水系消火薬剤において、リン酸アンモニウムは全体の３３重量％〜４７重量％の割合で添加されている。
Hereinafter, an example of an embodiment of a fire extinguishing agent according to the present invention will be described in detail.
The fire extinguisher of this example consists of what added the foaming component to the water-based fire extinguishing agent which added the infiltrant to water. In the water-based fire extinguishing agent in which an infiltrant is added to water, a known water-based fire extinguishing agent is used. In this example, ammonium phosphate is used as a component that brings about a negative catalytic effect of the combustion reaction. . In the water-based fire extinguishing agent used in this example, ammonium phosphate is added at a ratio of 33 wt% to 47 wt% of the whole.
水系消火薬剤に添加される発泡成分にあっては、蛋白泡消火薬剤、合成界面活性剤泡消火薬剤などの公知の発泡成分が使用される。浸潤剤入り水系消火薬剤に添加した発泡成分の添加量は、浸潤剤入り水系消火薬剤１００に対し０．５重量％〜６．０重量％の割合で添加されている。 As the foaming component added to the water-based fire extinguishing agent, known foaming components such as a protein foam extinguishing agent and a synthetic surfactant foam extinguishing agent are used. The addition amount of the foaming component added to the water-based fire extinguishing agent containing the infiltrant is added in a ratio of 0.5 wt% to 6.0 wt% with respect to the water-based fire extinguishing agent 100 containing the infiltrating agent.
このように配合された消火薬剤は、消火設備からの放出時に、泡ノズルや泡ヘッド等の発泡装置を通すことにより放出される。発泡装置を通った消火薬剤は、一部が発泡した状態で放出され、泡を含んだ消火薬剤が防火対象物にかかる。消火薬剤は、添加されている浸潤剤の作用により防火対象物の隙間等へ浸透することにより消火性能を発揮するとともに、含まれている泡により防火対象物の表面に付着し、防火対象物からの直ぐの脱落が阻止され一定時間付着した状態が保たれることにより延焼防止性能を発揮する。 The fire extinguishing agent blended in this way is released by passing through a foaming device such as a foam nozzle or a foam head at the time of release from the fire extinguishing equipment. The fire-extinguishing agent that has passed through the foaming device is released in a partially foamed state, and the fire-extinguishing agent containing bubbles is applied to the fire-protecting object. The fire extinguishing agent exerts fire extinguishing performance by penetrating into the gaps of the fire prevention object due to the action of the added infiltrant, and adheres to the surface of the fire prevention object by the contained foam, and from the fire prevention object This prevents fires from falling off immediately and keeps them attached for a certain period of time.
本例では、浸潤剤入り水系消火薬剤に添加した発泡成分の添加量は、浸潤剤入り水系消火薬剤１００に対し０．５重量％〜６．０重量％の割合で添加されている。浸潤剤入り水系消火薬剤に添加した発泡成分の添加量を、浸潤剤入り水系消火薬剤１００に対し０．５重量％〜６．０重量％の割合で添加することにより、消火性能と延焼防止性能を併せ持つ消火薬剤を得ることができる。
発泡成分の添加量が０．５重量％未満であると、放出された消火剤の発泡率が低く、防火対象物にかかった消火剤は延焼防止性能を発揮するまでに至らず、また６．０重量％を超えると発泡率が高くなり、泡が消火薬剤の浸潤剤が添加されている消火薬剤の浸透を阻止し消火性能に難が生じる。
In this example, the addition amount of the foaming component added to the water-based fire extinguishing agent containing the infiltrant is added at a ratio of 0.5 wt% to 6.0 wt% with respect to the water-based fire extinguishing agent 100 containing the infiltrating agent. Firefighting performance and fire spread prevention performance by adding the amount of foaming component added to the water-based fire-extinguishing agent containing the infiltrating agent at a ratio of 0.5% to 6.0% by weight with respect to the water-based fire-extinguishing agent 100 containing the infiltrating agent. Can be obtained.
If the added amount of the foaming component is less than 0.5% by weight, the foaming rate of the fire extinguisher released is low, and the fire extinguishing agent applied to the fire prevention object does not reach the fire spread prevention performance. If it exceeds 0% by weight, the foaming rate becomes high, and the foam prevents the penetration of the fire-extinguishing agent to which the infiltration agent of the fire-extinguishing agent is added.
上記の消火薬剤は、泡ノズルや泡ヘッド等の発泡装置を備えた泡消火設備で使用される。
泡消火設備は、泡を含んだ消火薬剤を放出するので、放出された消火薬剤は、消火性能と延焼防止性能を併せ持ち、消火効果と延焼防止効果を発揮することができ、これにより、消火効果と延焼防止効果を得るのに必要な消火薬剤の量が少なくなるので、結果として、泡消火設備がコンパクトなものとなり、泡消火設備コストの削減、占有空間の削減が可能となる。
The above fire extinguishing agent is used in a foam fire extinguishing facility equipped with a foaming device such as a foam nozzle or a foam head.
Since the foam fire extinguishing equipment emits foam-containing fire extinguishing agent, the fire extinguishing agent released has both fire extinguishing performance and fire spread prevention performance, and can exhibit fire extinguishing effect and fire spread preventing effect, thereby reducing the fire extinguishing effect As a result, the amount of fire extinguishing agent necessary to obtain the effect of preventing the spread of fire is reduced. As a result, the foam fire extinguishing equipment becomes compact, and it is possible to reduce the cost of the foam fire extinguishing equipment and the occupied space.
