［第１実施形態］
＜エアロゾル消火装置の全体構成＞
　図１を参照して、第１実施形態に係るエアロゾル消火装置１を説明する。第１実施形態に係るエアロゾル消火装置１は、設置面９０から突出するように設けられるタイプの消火装置であり、図１に示すように、容器１１、消火剤１２、点火具１３、冷却材層１４、スペーサ１５、及びシール材１６を含んで構成される。以下、エアロゾル消火装置１の各構成要素を順に説明する。 [First Embodiment]
<Overall configuration of aerosol fire extinguishing device>
With reference to FIG. 1, the aerosol fire extinguishing apparatus 1 which concerns on 1st Embodiment is demonstrated. The aerosol fire extinguishing apparatus 1 according to the first embodiment is a fire extinguishing apparatus of a type provided so as to protrude from the installation surface 90. As shown in FIG. 1, the container 11, the extinguishing agent 12, the igniter 13, and the coolant layer 14, a spacer 15, and a sealing material 16. Hereinafter, each component of the aerosol fire extinguishing apparatus 1 is demonstrated in order.
（容器）
　容器１１は、消火剤１２、冷却材層１４、スペーサ１５、及びシール材１６を収納する円筒状の部材である。容器１１は、後述するエアロゾルの発生により上昇する内圧（例えば、５ＭＰａ）に耐えられるように、例えばアルミニウムやステンレス鋼のような金属材料で作製される。 (container)
The container 11 is a cylindrical member that houses the fire extinguishing agent 12, the coolant layer 14, the spacer 15, and the sealing material 16. The container 11 is made of, for example, a metal material such as aluminum or stainless steel so that it can withstand an internal pressure (for example, 5 MPa) that rises due to generation of aerosol, which will be described later.
　容器１１は、設置面９０側の端部に開口部を有するとともに、開口部を形成する縁部から延設されたフランジ２１を有する。フランジ２１は、容器１１を例えばボルト４１，４２で設置面９０に固定するために設けられ、容器１１の本体と一体的に形成されている。したがって、容器１１を設置面９０に取り付けるための治具を別途用意する必要はない。 The container 11 has an opening at the end on the installation surface 90 side, and has a flange 21 extending from the edge forming the opening. The flange 21 is provided to fix the container 11 to the installation surface 90 with bolts 41 and 42, for example, and is formed integrally with the main body of the container 11. Therefore, it is not necessary to separately prepare a jig for attaching the container 11 to the installation surface 90.
　容器１１の開口部は、フランジ２１を覆うように装着されるカバー１７によって封止される。カバー１７は、例えばネジ留め、接着剤、かしめのような固定手段によってフランジ２１に固定されてよい。また、カバー１７は、消火剤１２の燃焼により生ずる熱がカバー１７を介して設置面９０へ伝導することを抑制するべく、設置面９０から離間した状態で設置面９０に取り付けられてもよい。カバー１７には、点火具１３を挿入するための孔２８が形成されている。 The opening of the container 11 is sealed by a cover 17 that is mounted so as to cover the flange 21. The cover 17 may be fixed to the flange 21 by fixing means such as screwing, adhesive, or caulking. Further, the cover 17 may be attached to the installation surface 90 in a state of being separated from the installation surface 90 in order to suppress heat generated by the combustion of the extinguishing agent 12 from being transmitted to the installation surface 90 via the cover 17. A hole 28 for inserting the ignition tool 13 is formed in the cover 17.
　容器１１における他方の端部、つまり開口部とは反対側の端部は、底面２２によって覆われている。底面２２には、エアロゾルの噴出孔２３，２４が形成されている。底面２２もまた、容器１１本体と一体的に形成されている。 The other end of the container 11, that is, the end opposite to the opening is covered with the bottom surface 22. Aerosol ejection holes 23 and 24 are formed on the bottom surface 22. The bottom surface 22 is also formed integrally with the main body of the container 11.
　容器１１の内径は、開口部から底面２２に向かう途中において縮小し、段差２５を形成している。換言すれば、段差２５は、容器１１を開口部から底面２２に向かう途中で絞ることで形成される。段差２５から底面２２（正確にはシール材１６）までの容器１１の内面は、案内部２６を構成し、例えば砲身のように、エアロゾルが噴出孔２３，２４から図１の噴出方向Ａに噴出されるようにエアロゾルを案内する役割を果たす。かかる案内部２６の延在方向の長さは、エアロゾル消火装置１から噴出されるエアロゾルに求められる指向性、つまりエアロゾルがエアロゾル消火装置１からどれぐらい離れた消火対象物に届く必要があるか、に応じて決定されてよい。 The inner diameter of the container 11 is reduced on the way from the opening toward the bottom surface 22 to form a step 25. In other words, the step 25 is formed by squeezing the container 11 on the way from the opening to the bottom surface 22. The inner surface of the container 11 from the step 25 to the bottom surface 22 (more precisely, the sealing material 16) constitutes a guide portion 26, and aerosol is ejected from the ejection holes 23 and 24 in the ejection direction A of FIG. It plays the role of guiding the aerosol. The length of the guide portion 26 in the extending direction is the directivity required for the aerosol ejected from the aerosol fire extinguishing apparatus 1, that is, how far the aerosol needs to reach the fire extinguishing object from the aerosol fire extinguishing apparatus 1. May be determined according to
　本実施形態において、容器１１は一筒のみで構成されており、容器１１に直接、消火剤１２等の収納物が装着される。つまり、収納物を保持するための内容器を必要としない。したがって、組立ての簡素化及びコストダウンが可能となる。 In this embodiment, the container 11 is composed of only one cylinder, and a stored item such as a fire extinguishing agent 12 is directly attached to the container 11. That is, an inner container for holding the stored items is not required. Therefore, the assembly can be simplified and the cost can be reduced.
（消火剤）
　消火剤１２は、容器１１において開口部の近傍に収納され、燃焼によりエアロゾルを発生させる。消火剤１２は、塩素酸カリウムとエアロゾル発生成分とを含む非化薬の組成物でもよく、本実施形態では円盤状を呈している。消火剤１２の組成については追って述べる。 (Extinguishing agent)
The fire extinguisher 12 is stored in the container 11 in the vicinity of the opening, and generates aerosol by combustion. The fire extinguisher 12 may be a non-chemical composition containing potassium chlorate and an aerosol-generating component, and has a disk shape in this embodiment. The composition of the fire extinguishing agent 12 will be described later.
　消火剤１２は、開口部を臨む面に、点火具１３を装着するための窪み（凹部）３１を有する。かかる窪み３１は、底面２２側の表面まで貫通しておらず、点火具１３を底面２２側に露出させないように構成されている。つまり、窪み３１の深さは消火剤１２の厚みより小さい。かかる構成により、点火具１３より噴出し得る火花や火炎が噴出孔２３，２４から内部に飛び出すことを防止できる。これを防止することにより、容器１１内を有効に活用してエアロゾルを確実に案内することができる。また、かかる構成は、貫通構造で孔内に伝火具を挿入している構造と比べて、構造の簡素化とコストダウンにおいて有利である。 The extinguishing agent 12 has a recess (concave portion) 31 for mounting the igniter 13 on the surface facing the opening. The recess 31 does not penetrate to the surface on the bottom surface 22 side and is configured not to expose the igniter 13 to the bottom surface 22 side. That is, the depth of the recess 31 is smaller than the thickness of the extinguishing agent 12. With this configuration, it is possible to prevent sparks or flames that can be ejected from the igniter 13 from jumping out from the ejection holes 23 and 24. By preventing this, the inside of the container 11 can be effectively used to reliably guide the aerosol. Further, such a configuration is advantageous in terms of simplification of the structure and cost reduction, compared with a structure in which a fire transfer tool is inserted into the hole with a through structure.
　消火剤１２は、底面２２側の面において金網１８に当接している。したがって、消火剤１２は、カバー１７と金網１８との間に挟まれている。金網１８は、後述する金網３３，３４と同様に、通気性のよい素材で作製されている。したがって、消火剤１２において発生したエアロゾルは、金網１８を通過して冷却材層１４に流入することになる。 The fire extinguishing agent 12 is in contact with the wire mesh 18 on the bottom 22 side surface. Therefore, the fire extinguishing agent 12 is sandwiched between the cover 17 and the wire mesh 18. The wire mesh 18 is made of a material having good air permeability, like the wire meshes 33 and 34 described later. Therefore, the aerosol generated in the fire extinguisher 12 passes through the wire mesh 18 and flows into the coolant layer 14.
（点火具）
　点火具１３は、カバー１７の孔２８を介して消火剤１２の窪み３１に装着され、エアロゾルを発生させるべく消火剤１２に着火する。点火具１３は、例えば公知のイニシエータや雷管でよい。なお、火災の発生を点火具１３に伝えて作動させるために、図示しない熱センサが設けられてもよい。 (Ignition tool)
The igniter 13 is attached to the depression 31 of the extinguishing agent 12 through the hole 28 of the cover 17 and ignites the extinguishing agent 12 so as to generate aerosol. The igniter 13 may be a known initiator or detonator, for example. Note that a thermal sensor (not shown) may be provided in order to transmit the fire occurrence to the igniter 13 to operate.
（冷却材層）
　冷却材層１４は、容器１１において消火剤１２より底面２２側に収納される部材であって、冷却材３２と、冷却材３２を保持する金網３３，３４と、を含む。本実施形態では、冷却材層１４は、全体として円盤状ないし円柱状を呈しており、その径は、容器１１の開口部側の内径（大きい方の内径）より小さく、底面２２側の内径（小さい方の内径）より大きい。したがって、冷却材層１４は、容器１１に形成された段差２５に係止する。 (Coolant layer)
The coolant layer 14 is a member housed on the bottom surface 22 side of the fire extinguishing agent 12 in the container 11, and includes a coolant 32 and wire meshes 33 and 34 that hold the coolant 32. In the present embodiment, the coolant layer 14 has a disk shape or a columnar shape as a whole, and the diameter thereof is smaller than the inner diameter (larger inner diameter) on the opening side of the container 11, and the inner diameter ( The smaller inner diameter). Therefore, the coolant layer 14 is locked to the step 25 formed in the container 11.
　冷却材３２は、消火剤１２から発生したエアロゾルを冷却する。冷却材３２は、例えばアルミナ、シリカ、耐熱性セラミックのような無機酸化物を材料とする球体でもよいし、金属製の粒状体でもよい。あるいは、冷却材３２は、円筒状や円筒中空状を呈していてもよい。本実施形態では、複数のアルミナボールが冷却材３２を構成している。 The cooling material 32 cools the aerosol generated from the fire extinguishing agent 12. The coolant 32 may be a sphere made of an inorganic oxide such as alumina, silica, or heat-resistant ceramic, or may be a metal granule. Alternatively, the coolant 32 may have a cylindrical shape or a cylindrical hollow shape. In the present embodiment, a plurality of alumina balls constitute the coolant 32.
　金網３３，３４は、冷却材３２を挟み込んで保持する。金網３３，３４は、例えば、金属製の線材を網目状ないしメッシュ状に編むことで形成されてもよい。冷却材３２を構成する複数の球体を金網３３，３４で固定することにより、冷却材３２などの各部材における高さのバラつきを吸収することができる。なお、金網３３，３４は、例えば発泡性高分子素材や金属製板バネでもよい。 Metal meshes 33 and 34 hold the coolant 32 in between. The metal nets 33 and 34 may be formed, for example, by knitting a metal wire into a mesh or mesh. By fixing the plurality of spheres constituting the coolant 32 with the metal meshes 33 and 34, variations in height of each member such as the coolant 32 can be absorbed. The wire nets 33 and 34 may be, for example, a foamable polymer material or a metal leaf spring.
　金網３３，３４は、上述したように網目状ないしメッシュ状を呈することから、気体を通過させることができる。したがって、開口側から金網３３に流入したエアロゾルは、アルミナボール（冷却材３２）の間を通り、金網３４を通過して、底面２２側に抜けることになる。 Since the metal meshes 33 and 34 have a mesh shape or a mesh shape as described above, gas can pass therethrough. Therefore, the aerosol that has flowed into the wire mesh 33 from the opening side passes between the alumina balls (coolant 32), passes through the wire mesh 34, and escapes to the bottom surface 22 side.
　本実施形態では、冷却材層１４は一層のみ設けられている。したがって、例えば大小のアルミナボールをそれぞれ含む２層の冷却材層を有するタイプのエアロゾル消火装置と比べて、構造が簡素であるから、組立が容易であるとともに、コストダウンにつながる。 In this embodiment, only one coolant layer 14 is provided. Therefore, for example, the structure is simple as compared with an aerosol fire extinguishing apparatus having two coolant layers each including large and small alumina balls, which facilitates assembly and leads to cost reduction.
（スペーサ）
　スペーサ１５は、消火剤１２（金網１８）と冷却材層１４との間に設けられて両部材を離間させる。スペーサ１５は、例えば容器１１の内周面に沿って配置されるリング部材でもよく、消火剤１２と冷却材層１４とを一定距離だけ離間させるように一定の厚みを有する。 (Spacer)
The spacer 15 is provided between the fire extinguishing agent 12 (metal mesh 18) and the coolant layer 14, and separates both members. The spacer 15 may be, for example, a ring member disposed along the inner peripheral surface of the container 11 and has a certain thickness so that the extinguishing agent 12 and the coolant layer 14 are separated by a certain distance.
（シール材）
　シール材１６は、底面２２の噴出孔２３，２４を封止するとともに、容器１１の内圧が所定値を超えると噴出孔２３，２４からエアロゾルを噴出させる。シール材１６は、防水・防油・防湿用シーラントであり、例えばアルミニウム層の３０～８０μｍと、５０μｍの粘着剤層とを有してもよい。 (Seal material)
The sealing material 16 seals the ejection holes 23 and 24 on the bottom surface 22 and causes the aerosol to be ejected from the ejection holes 23 and 24 when the internal pressure of the container 11 exceeds a predetermined value. The sealing material 16 is a waterproof / oilproof / moistureproof sealant and may have, for example, an aluminum layer of 30 to 80 μm and a 50 μm pressure-sensitive adhesive layer.
＜消火剤組成物＞
　ここで、本実施形態で用いられる消火剤組成物について説明する。消火剤組成物としては、火薬の分類に属するものであっても属しないものであっても、種々の消火剤組成物を用いることができる。なかでも、本実施形態における消火剤１２としては、例えば、燃料（Ａ成分）２０～５０質量％及び塩素酸塩（Ｂ成分）８０～５０質量％を含有し、更に前記燃料及び前記塩素酸塩の合計量１００質量部に対して、６～１０００質量部のカリウム塩（Ｃ成分）を含有し、熱分解開始温度が９０℃超～２６０℃の範囲の消火剤組成物を好適に使用することができる。 <Fire extinguisher composition>
Here, the fire extinguisher composition used in the present embodiment will be described. As a fire extinguisher composition, various fire extinguisher compositions can be used regardless of whether they belong to the classification of explosives or not. Among them, the extinguishing agent 12 in this embodiment includes, for example, 20 to 50% by mass of fuel (component A) and 80 to 50% by mass of chlorate (component B), and further includes the fuel and the chlorate.

　かかるＢ成分の塩素酸塩としては、例えば塩素酸カリウム、塩素酸ナトリウム、塩素酸ストロンチウム、塩素酸アンモニウム及び塩素酸マグネシウムのうちの少なくとも１種から選ばれるものが好ましい。 The B component chlorate is preferably selected from at least one of potassium chlorate, sodium chlorate, strontium chlorate, ammonium chlorate and magnesium chlorate.
　ここで、Ａ成分の燃料とＢ成分の塩素酸塩の合計１００質量％中の含有割合は、以下のとおりである。
　Ａ成分：２０～５０質量％
　　　　　好ましくは２５～４０質量％
　　　　　より好ましくは２５～３５質量％
　Ｂ成分：８０～５０質量％
　　　　　好ましくは７５～６０質量％
　　　　　より好ましくは７５～６５質量％ Here, the content ratio in 100 mass% of the fuel of component A and the chlorate of component B is as follows.

Preferably 25-40% by weight
More preferably 25 to 35% by mass
B component: 80-50 mass%
Preferably 75-60% by weight
More preferably 75 to 65% by mass
　次に、Ｃ成分のカリウム塩は、Ａ成分とＢ成分の燃焼により生じた熱エネルギーによりエアロゾル（カリウムラジカル）を発生させるための成分である。 Next, the potassium salt of component C is a component for generating aerosol (potassium radical) by the heat energy generated by the combustion of component A and component B.
　かかるＣ成分のカリウム塩としては、例えば酢酸カリウム、プロピオン酸カリウム、クエン酸一カリウム、クエン酸二カリウム、クエン酸三カリウム、エチレンジアミン四酢酸三水素一カリウム、エチレンジアミン四酢酸二水素二カリウム、エチレンジアミン四酢酸一水素三カリウム、エチレンジアミン四酢酸四カリウム、フタル酸水素カリウム、フタル酸二カリウム、シュウ酸水素カリウム、シュウ酸二カリウム及び重炭酸カリウムのうちの少なくとも１種から選ばれるものが好ましい。 Examples of the potassium salt of component C include potassium acetate, potassium propionate, monopotassium citrate, dipotassium citrate, tripotassium citrate, ethylenediaminetetraacetic acid monohydrogentripotassium, ethylenediaminetetraacetic acid dipotassium dihydrogen, ethylenediaminetetraacetate. Preference is given to at least one selected from tripotassium acetate hydrogen acetate, tetrapotassium ethylenediaminetetraacetate, potassium hydrogen phthalate, dipotassium phthalate, potassium hydrogen oxalate, dipotassium oxalate and potassium bicarbonate.
　Ｃ成分の含有割合は、Ａ成分とＢ成分の合計量１００質量部に対して、６～１０００質量部であるのが好ましく、より好ましくは１０～９００質量部である。 The content ratio of the C component is preferably 6 to 1000 parts by mass, more preferably 10 to 900 parts by mass with respect to 100 parts by mass of the total amount of the A component and the B component.
　更に、本実施形態の消火剤組成物は、熱分解開始温度が９０℃超～２６０℃の範囲のものであり、好ましくは１５０℃超～２６０℃のものである。このような熱分解開始温度の範囲は、上記のＡ成分、Ｂ成分及びＣ成分を上記の割合で組み合わせることで調製することができる。 Furthermore, the fire extinguisher composition of the present embodiment has a thermal decomposition starting temperature in the range of over 90 ° C. to 260 ° C., preferably over 150 ° C. to 260 ° C. Such a range of the thermal decomposition start temperature can be prepared by combining the A component, the B component, and the C component in the above ratio.

It can be ignited and burned to generate an aerosol (potassium radical) derived from the C component and extinguish the fire.
　なお、室内にある可燃物として一般的な木材の引火温度は２６０℃であり、火気を取扱う場所に設置する自動火災報知設備の熱感知器の一般的な作動温度である９０℃以下では起動しない条件に熱分解開始温度を設定することで、速やかな消火ができると共に、前記熱感知器の誤作動も防止できる。特に、熱感知器の最大設定温度は１５０℃であるため、熱分解開始温度の下限値を１５０℃超に設定することで高い汎用性が得られる。 In addition, the flammable temperature of common wood as a combustible material in the room is 260 ° C, and it does not start below 90 ° C, which is the general operating temperature of the heat detector of automatic fire alarm equipment installed in a place where fire is handled. By setting the thermal decomposition start temperature as a condition, it is possible to quickly extinguish the fire and prevent malfunction of the heat sensor. In particular, since the maximum set temperature of the heat detector is 150 ° C., high versatility can be obtained by setting the lower limit value of the thermal decomposition start temperature to over 150 ° C.
＜エアロゾル消火装置の組立て及び使用＞
　上述した構成を有するエアロゾル消火装置１は、例えば次のように組み立てられる。
　まず、容器１１を用意し、底面２２にシール材１６を張り付ける。次いで、冷却材層１４を取り付ける。例えば、金網３４を容器１１に挿入し、段差２５に係止する。その状態で複数のアルミナボール（冷却材３２）を金網３４上に一様に載置し、更に金網３３をアルミナボール上に載置する。そして、スペーサ１５を挿入し、更に金網１８を挿入する。この状態で、金網１８上に消火剤１２を載置する。 <Assembly and use of aerosol fire extinguishing device>
The aerosol fire extinguishing apparatus 1 having the above-described configuration is assembled as follows, for example.
First, the container 11 is prepared, and the sealing material 16 is attached to the bottom surface 22. Next, the coolant layer 14 is attached. For example, the wire mesh 34 is inserted into the container 11 and locked to the step 25. In this state, a plurality of alumina balls (cooling material 32) are uniformly placed on the wire mesh 34, and the wire mesh 33 is further placed on the alumina ball. Then, the spacer 15 is inserted, and the wire mesh 18 is further inserted. In this state, the fire extinguishing agent 12 is placed on the wire mesh 18.
　このようにして容器１１に全ての収納物を収めたうえで、容器１１の開口部をカバー１７で塞ぐ。このとき、消火剤１２の上面（窪み３１が形成された面）をカバー１７で押し込むようにして、消火剤１２を容器１１の内部に納める。このようにすることで、消火剤１２や冷却材３２の寸法のバラツキは、金網１８，３３，３４の変形によって吸収される。併せて、カバー１７をはんだ付け、かしめ、ネジ止めなどにより封止してもよい。 In this way, after all the stored items are stored in the container 11, the opening of the container 11 is closed with the cover 17. At this time, the fire extinguishing agent 12 is placed inside the container 11 such that the upper surface of the extinguishing agent 12 (the surface on which the recess 31 is formed) is pushed in by the cover 17. By doing in this way, the dispersion | variation in the dimension of the fire extinguisher 12 or the cooling material 32 is absorbed by the deformation | transformation of the metal mesh 18,33,34. In addition, the cover 17 may be sealed by soldering, caulking, screwing, or the like.
　そして、点火具１３を、カバー１７の孔２８を介して消火剤１２の窪み３１に装着し、シール材で封止する。併せて、必要な温度センサ（不図示）を点火具１３に接続してもよい。 Then, the igniter 13 is mounted in the depression 31 of the extinguishing agent 12 through the hole 28 of the cover 17 and sealed with a sealing material. In addition, a necessary temperature sensor (not shown) may be connected to the igniter 13.
　このようにして組み立てられたエアロゾル消火装置１は、容器１１のフランジ２１が設置面９０に例えばネジ止めされることで、設置面９０に固定される。このとき、容器１１の底面２２が消火対象物に対向するように、エアロゾル消火装置１を設置するとよい。 The aerosol fire extinguishing apparatus 1 assembled in this way is fixed to the installation surface 90 by, for example, screwing the flange 21 of the container 11 to the installation surface 90. At this time, the aerosol fire extinguishing apparatus 1 may be installed so that the bottom surface 22 of the container 11 faces the fire extinguishing target.
　エアロゾル消火装置が設置された状態においては、温度センサの計測値が所定の設定値を超えると、点火具１３は、消火剤１２を燃焼させるべく消火剤１２に点火する。消火剤１２の燃焼により発生したエアロゾルは、冷却材層１４において冷却され、容器１１の案内部２６内に充満する。そして、エアロゾルにより容器１１の内部圧力が所定値まで高まると、シール材１６が破れて、エアロゾルが噴出孔２３，２４から噴出する。このとき、エアロゾルは、案内部２６に沿って案内されることにより、図１の噴射方向Ａに方向づけられる。このようにしてエアロゾルが消火対象物に飛散することで、消火対象物が消火ないし抑制される。 In the state where the aerosol fire extinguishing device is installed, when the measured value of the temperature sensor exceeds a predetermined set value, the igniter 13 ignites the fire extinguisher 12 to burn the fire extinguisher 12. The aerosol generated by the combustion of the extinguishing agent 12 is cooled in the coolant layer 14 and fills the guide portion 26 of the container 11. When the internal pressure of the container 11 is increased to a predetermined value due to the aerosol, the sealing material 16 is broken and the aerosol is ejected from the ejection holes 23 and 24. At this time, the aerosol is guided in the injection direction A of FIG. In this way, the aerosol is scattered on the fire extinguishing object, so that the fire extinguishing object is extinguished or suppressed.
＜第１実施形態の効果＞
　第１実施形態に係るエアロゾル消火装置１によれば、フランジ２１が容器１１の本体と一体的に設けられる。また、冷却材層及び消火剤は容器１１に直接装着され、これら部材を取り付けるために内容器は利用されない。したがって、部品点数を減らすことができ、組立及び取付が容易になるとともに、コストの削減につながる。 <Effects of First Embodiment>
According to the aerosol fire extinguishing apparatus 1 according to the first embodiment, the flange 21 is provided integrally with the main body of the container 11. Further, the coolant layer and the fire extinguishing agent are directly attached to the container 11, and the inner container is not used for attaching these members. Therefore, the number of parts can be reduced, and assembling and mounting are facilitated, and the cost is reduced.
　また、消火剤１２の開口部側に形成された窪み３１は、底面２２側に貫通していないので、点火具１３から発生した火花や火炎が底面２２の噴出孔２３，２４から飛び出ることが防止される。また、このような構成により、伝火具が不要となるので、構造の簡素化を図ることができる。 Further, since the depression 31 formed on the opening side of the extinguishing agent 12 does not penetrate to the bottom surface 22 side, it is possible to prevent sparks and flames generated from the igniter 13 from jumping out from the ejection holes 23 and 24 of the bottom surface 22. Is done. Moreover, since such a structure eliminates the need for a fire transfer tool, the structure can be simplified.
　更に、エアロゾル消火装置１を構成する主要な部品は、容器１１、消火剤１２、点火具１３、冷却材３２、１個のスペーサ１５、３個の金網１８，３３，３４で足り、部品点数の減少によるコスト削減が可能となる。 Further, the main components constituting the aerosol fire extinguishing apparatus 1 are the container 11, the fire extinguishing agent 12, the igniter 13, the coolant 32, the one spacer 15, and the three wire meshes 18, 33, 34, and the number of parts is sufficient. Cost reduction by reduction is possible.
　上記の構成を有するエアロゾル消火装置１では、常温での燃焼最大内圧を５ＭＰａ以下、例えば０．５～１．５Ｍｐａレベルにまで抑えることが可能である。したがって、容器１１の厚みを薄くしたり、軽量の材料を用いることができたりするので、装置全体の軽量化及び小型化を図ることができる。 In the aerosol fire extinguishing apparatus 1 having the above-described configuration, the maximum combustion internal pressure at room temperature can be suppressed to 5 MPa or less, for example, 0.5 to 1.5 MPa level. Therefore, since the thickness of the container 11 can be reduced or a light material can be used, the entire apparatus can be reduced in weight and size.

＜エアロゾル消火装置の組立て及び使用＞
　上述した構成を有する第２実施形態に係るエアロゾル消火装置５は、例えば次のように組み立てられる。 <Assembly and use of aerosol fire extinguishing device>
The aerosol fire extinguishing apparatus 5 according to the second embodiment having the above-described configuration is assembled as follows, for example.
　まず、用意した容器５１に消火剤５２を挿入する。その際、消火剤５２を、窪みが形成された面が容器５１の底面６２に対向するように配置する。次いで、支持板５８、スペーサ５５、冷却材層５４、スペーサ５６の順に、容器５１内に挿入する。 First, the fire extinguishing agent 52 is inserted into the prepared container 51.

　かかるエアロゾル消火装置５の使用方法は、第１実施形態と同様であり、図示しない温度センサが所定値以上の温度を検知すると、点火具５３が消火剤５２に点火し、エアロゾルを発生させる。発生したエアロゾルは、冷却材層５４において冷却された後、案内部６５に送られる。そして、容器５１の内部圧力が所定値を超えると、シール材５７が破れ、エアロゾルが噴出孔６３，６４から外部に噴出する。そのとき、エアロゾルは、案内部６５において噴出方向Ｂに方向付けられる。そして、エアロゾルが消火対象物に飛散することで、消火対象物が消火ないし抑制される。 The method of using the aerosol fire extinguishing apparatus 5 is the same as that of the first embodiment. When a temperature sensor (not shown) detects a temperature equal to or higher than a predetermined value, the igniter 53 ignites the fire extinguishing agent 52 to generate aerosol. The generated aerosol is cooled in the coolant layer 54 and then sent to the guide portion 65. When the internal pressure of the container 51 exceeds a predetermined value, the sealing material 57 is broken and the aerosol is ejected from the ejection holes 63 and 64 to the outside. At that time, the aerosol is directed in the ejection direction B in the guide portion 65. And, the fire extinguishing object is extinguished or suppressed by the aerosol scattering to the fire extinguishing object.

　第２実施形態に係るエアロゾル消火装置５によれば、フランジ６１が容器５１の本体と一体的に設けられる。また、冷却材層５４及び消火剤５２は、容器５１に直接装着される。したがって、部品点数を減らすことができ、組立及び取付が容易になるとともに、コストの削減につながる。 <Effects of Second Embodiment>
According to the aerosol fire extinguishing apparatus 5 according to the second embodiment, the flange 61 is provided integrally with the main body of the container 51. Further, the coolant layer 54 and the fire extinguishing agent 52 are directly attached to the container 51. Therefore, the number of parts can be reduced, and assembling and mounting are facilitated, and the cost is reduced.
　また、消火剤５２に形成された窪み７１により、点火具５３から発生した火花や火炎が底面の噴出孔から飛び出ることを防止することができる。また、伝火具が不要となるので、構造の簡素化を図ることができる。 Also, the depression 71 formed in the extinguishing agent 52 can prevent the spark or flame generated from the igniter 53 from jumping out from the bottom ejection hole. Moreover, since a fire transfer tool is not required, the structure can be simplified.
　更に、エアロゾル消火装置５を構成する主要な部品は、容器５１、消火剤５２、点火具５３、冷却材層５４、２個のスペーサ５５，５６、支持板５８だけで足り、更なる部品点数の減少によるコスト削減が可能となる。 Further, the main components constituting the aerosol fire extinguishing apparatus 5 are only the container 51, the fire extinguishing agent 52, the igniter 53, the coolant layer 54, the two spacers 55 and 56, and the support plate 58, and the number of additional parts is increased. Cost reduction by reduction is possible.
　また、コネクタ形式の点火具５３は、点火具５３の装着及び交換を容易にするので、組立や点検の作業を軽減させることにつながる。 In addition, the connector-type igniter 53 facilitates the mounting and replacement of the igniter 53, leading to a reduction in assembly and inspection work.
