Description
本発明は、蒸気の自己分解伝播性の評価装置および評価方法に関する。詳しくは、自然発火性を有する蒸気の自己分解伝播性の評価にも好適な評価装置および評価方法に関する。 The present invention relates to an evaluation apparatus and evaluation method for vapor self-decomposition propagation. Specifically, the present invention relates to an evaluation apparatus and an evaluation method that are also suitable for evaluating the self-decomposition propagation property of steam having spontaneous ignition.
酸化エチレンガスは、アセチレンやエチレンと同じように、空気等の支燃性ガスが存在しなくてもそれ自体単独でエネルギーが与えられると分解伝播性を示すが、酸化エチレンの分解爆発実験を行い、分解反応のメカニズムを検討した事例が知られている（非特許文献１参照。）。
この実験においては、上部にガス導入用および排出用の金属管、圧力計が設けられたステンレス製の耐圧容器の胴部上方に温度測定のための熱電対を挿入した保護管、下部には２本の電極間にろう付けした白金線を、直流電流で溶断することによって着火エネルギーを付与する手段を設け、容器に酸化エチレンを充填し、白金線の溶断によって着火エネルギーを付与し、分解伝播による温度上昇の測定と、測定後のガス分析による酸化エチレンの残量から分解伝播の確認および解析を行っている。
しかしながら、この方法では、蒸気の自己分解伝播性を直接観察することができない。また、自己分解伝播速度は着火から熱電対で温度上昇を検出するまでの時間から求めることができるが、分解火炎が熱電対に到達するまでに消滅する部分伝播の場合には、自己分解伝播速度を求めることはできない。
Ethylene oxide gas, like acetylene and ethylene, exhibits decomposition propagation properties when it is given energy alone, even if no flammable gas such as air is present. An example of studying the mechanism of the decomposition reaction is known (see Non-Patent Document 1).
In this experiment, a metal tube for gas introduction and discharge at the top, a protective tube with a thermocouple for temperature measurement inserted above the barrel of a stainless steel pressure vessel provided with a pressure gauge, and 2 at the bottom A means for applying ignition energy by fusing a platinum wire brazed between two electrodes with a direct current is provided, filling the container with ethylene oxide, applying ignition energy by fusing the platinum wire, and by decomposition propagation Confirmation and analysis of decomposition propagation from the residual amount of ethylene oxide by measuring the temperature rise and gas analysis after the measurement.
However, this method cannot directly observe the self-decomposition propagation property of the vapor. The self-decomposition propagation speed can be calculated from the time from ignition until the temperature rise is detected by the thermocouple, but in the case of partial propagation where the decomposition flame disappears before reaching the thermocouple, the self-decomposition propagation speed Cannot be asked.
一方、有機金属等は空気中で自然発火性を有しており、しかも、その蒸気は空気が存在しなくても外部からのエネルギーによって自己分解を起こす可能性を有する物質であるが、実験の際に、自己分解による圧力上昇によって測定容器の外部に蒸気が漏洩した場合には、空気中の酸素によって発火する危険性を有するためからか、これまで実際に蒸気の自己分解伝播性を評価した例は見られない。
本発明の目的は、蒸気の自己分解伝播性を直接観察でき、自然発火性を有する蒸気でも安全に評価でき、更には、自己分解伝播速度を精度良く求めることができる蒸気の自己分解伝播性の評価装置および評価方法を提供することである。 The purpose of the present invention is to directly observe the self-decomposition propagating property of steam, and can safely evaluate even pyrophoric steam.

The present invention was completed by finding that it is possible to evaluate, and that the decomposition flame can be photographed with a high-speed video camera from the viewing window and the self-decomposition propagation speed can be accurately obtained from the imaging. This has led to the.

以下、図面を参照して本発明を詳細に説明する。図１は本発明の一実施形態である評価装置の断面模式図である。 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic sectional view of an evaluation apparatus according to an embodiment of the present invention.
評価装置１は、試料容器２と恒温槽３から構成されている。恒温槽３には覗き窓９、内部を不活性ガスで置換する手段である不活性ガスの供給管１４および排気管１５、恒温槽の温度を加熱制御するための手段１３（端子だけ図示している）が設けられ、更に分解エネルギー供給手段である放電電極４に通電するための通電手段１２（端子だけ図示している）が配置されている。
内部を不活性ガスで置換する手段で恒温槽内の雰囲気を不活性ガスで置換しておくことにより、試料が自然発火性であって、試料容器から仮に漏洩したとしても、発火することなく、安全に評価を行うことができる。
The evaluation device 1 includes a sample container 2 and a thermostatic chamber 3. The constant temperature chamber 3 has a viewing window 9, an inert gas supply pipe 14 and an exhaust pipe 15 which are means for replacing the inside with an inert gas, and a means 13 for controlling the temperature of the constant temperature chamber (only terminals are shown). In addition, an energizing means 12 (only the terminals are shown) for energizing the discharge electrode 4 which is a decomposition energy supply means is disposed.
By replacing the atmosphere in the thermostatic chamber with an inert gas by means of replacing the inside with an inert gas, even if the sample is pyrophoric and temporarily leaks from the sample container, it will not ignite, Evaluation can be performed safely.
試料容器（以下、単に容器と言うことがある。）２の上部には、試料の導入口５およびその栓６、試料の導入と内部ガスの排気を行う配管７およびバルブ８、および分解エネルギー供給手段４が取り付けられている。
試料容器２としては、ステンレスなどの金属製、ガラス製のものが用いられる。分解火炎を眼またはビデオカメラで観察するには、透明ガラス容器が用いられる。
試料の導入口５およびその栓６、試料の導入と内部ガスの排気を行う配管７およびバルブ８、分解エネルギー供給手段４の取り付け位置は特に限定されるものではないが、通常、試料の導入口５およびその栓６、試料の導入と内部ガスの排気を行う配管７およびバルブ８は容器の上部に、分解エネルギー供給手段４は下方に取り付けられる。
In the upper part of the sample container (hereinafter sometimes referred to simply as a container) 2, a sample inlet 5 and its stopper 6, a pipe 7 and a valve 8 for introducing the sample and exhausting the internal gas, and supply of decomposition energy Means 4 are attached.
As the sample container 2, one made of metal such as stainless steel or glass is used. A transparent glass container is used to observe the decomposition flame with an eye or a video camera.
The sample introduction port 5 and its stopper 6, the pipe 7 and valve 8 for introducing the sample and exhausting the internal gas, and the attachment position of the decomposition energy supply means 4 are not particularly limited, but usually the sample introduction port 5 and its stopper 6, a pipe 7 for introducing the sample and exhausting the internal gas, and a valve 8 are attached to the upper part of the container, and the decomposition energy supply means 4 is attached to the lower part.

固体試料を評価する場合には、通常、試料は導入口５から容器内に入れ、内部ガスの排気を配管７およびバルブ８で行う。なお、液体試料も導入口５から容器内に入れることは可能である。液体またはガス試料を評価する場合には、通常、配管７およびバルブ８を介して試料の導入、内部ガスの排気が行われる。配管７の先端にはバルブ８を開けても容器内のガスと容器外のガスが接触しないようにシリコン栓が取り付けられている。 When evaluating a solid sample, the sample is usually put into the container through the inlet 5 and the internal gas is exhausted by the pipe 7 and the valve 8. A liquid sample can also be put into the container from the inlet 5. When evaluating a liquid or gas sample, the sample is usually introduced and the internal gas is exhausted via the pipe 7 and the valve 8. A silicon stopper is attached to the tip of the pipe 7 so that the gas inside the container does not come into contact with the gas outside the container even if the valve 8 is opened.
自己分解伝播の評価は、自己分解伝播が発生した場合には、容器２内に分解火炎が発生し、導入口５に挿入してある栓６が飛び出すので、覗き窓から栓６の飛び出しを目視によって観察する。試料容器として透明ガラス容器を使用し、発生する分解火炎を目視によって観察してもよいし、また、透明ガラス容器を使用し、ビデオカメラを覗き窓の外部に配置し、分解火炎を撮影し、その撮像から確認してもよい。
撮像における分解火炎の移動距離とその時間から自己分解伝播速度を精度良く求めることができる。その際、ビデオカメラとしたは、高速度ビデオカメラを使用するのが好ましい。

Observe by. Using a transparent glass container as a sample container, the generated decomposition flame may be observed visually, or using a transparent glass container, placing a video camera outside the viewing window, photographing the decomposition flame, You may confirm from the imaging.
The self-decomposition propagation speed can be obtained with high accuracy from the moving distance and time of the decomposition flame in imaging. In this case, it is preferable to use a high-speed video camera as the video camera.
次にこの評価装置１を使用して蒸気の自己分解伝播性を評価する方法について説明する。
グローブボックス内に試料容器２を設置し、グローブボックス内を不活性ガスで置換する。室温で試料１０が固体の場合は、配管７およびバルブ８を介して容器２内も不活性ガスで置換する。試料導入口５の栓６を取り外して試料１０を容器２内に所定量入れた後、栓６を取り付け、配管７から真空ポンプによって容器２内の不活性ガスを排気する。
Next, a method for evaluating the self-decomposition propagation property of steam using the evaluation apparatus 1 will be described.
The sample container 2 is installed in the glove box, and the inside of the glove box is replaced with an inert gas. When the sample 10 is solid at room temperature, the inside of the container 2 is also replaced with an inert gas via the pipe 7 and the valve 8. After removing the stopper 6 from the sample inlet 5 and putting a predetermined amount of the sample 10 into the container 2, the stopper 6 is attached and the inert gas in the container 2 is exhausted from the pipe 7 by a vacuum pump.
室温で試料１０が液体の場合は、まず、シリンジに液体試料を入れておく。次に、配管７およびバルブ８を介して真空ポンプにより容器２内を真空にした後、バルブ８を閉じ、配管７の先端にシリコン栓を取り付ける。再びバルブ８を開け、液体試料を入れたシリンジの針を、シリコン栓を通して配管７から容器２内に挿入し、容器２内に液体試料を所定量入れた後、シリンジの針を引き抜く。シリコン栓によって、容器２内へグローブボックス内の不活性ガスが侵入することを防止する。 When the sample 10 is liquid at room temperature, first, the liquid sample is put in a syringe. Next, after the inside of the container 2 is evacuated by a vacuum pump through the pipe 7 and the valve 8, the valve 8 is closed and a silicon stopper is attached to the tip of the pipe 7. The valve 8 is opened again, and the syringe needle containing the liquid sample is inserted into the container 2 from the pipe 7 through the silicon stopper. After a predetermined amount of the liquid sample is put into the container 2, the syringe needle is pulled out. The silicon stopper prevents the inert gas in the glove box from entering the container 2.
グローブボックスから試料１０を入れた容器２を取り出し、恒温槽３内に容器２を設置する。恒温槽３内の雰囲気を不活性ガスで置換した後、恒温槽３を設定温度まで加熱し、試料１０の設定温度における飽和蒸気１１を容器２内に形成させる。次に、分解エネルギー供給手段４である放電電極に電圧をかけて放電電極の間に電気火花を発生させ、分解エネルギーを試料蒸気に与える。 The container 2 containing the sample 10 is taken out from the glove box, and the container 2 is installed in the thermostatic chamber 3. After replacing the atmosphere in the thermostat 3 with an inert gas, the thermostat 3 is heated to a set temperature, and a saturated vapor 11 at the set temperature of the sample 10 is formed in the container 2. Next, a voltage is applied to the discharge electrode as the decomposition energy supply means 4 to generate an electric spark between the discharge electrodes, and the decomposition energy is given to the sample vapor.
自己分解が伝播して試料蒸気全体が自己分解を起こすと、容器２の内部圧力の上昇により栓６が容器２の導入口５から飛び出す。この栓６の飛び出しの有無を覗き窓９から確認し、試料蒸気１１の自己分解伝播性の有無を判定する。また、容器２として透明ガラス容器を使用し、発生する分解火炎を目視によって観察し、また、透明ガラス容器を使用し、ビデオカメラを覗き窓の外部に配置し、分解火炎を撮影し、その撮像から自己分解伝播性の有無を確認してもよい。 When self-decomposition propagates and the entire sample vapor undergoes self-decomposition, the stopper 6 jumps out of the inlet 5 of the container 2 due to an increase in the internal pressure of the container 2. The presence or absence of this plug 6 is confirmed from the viewing window 9 and the presence or absence of self-decomposition propagation property of the sample vapor 11 is determined. Also, a transparent glass container is used as the container 2 and the generated decomposition flame is visually observed. Also, the transparent glass container is used, the video camera is placed outside the viewing window, the decomposition flame is photographed, and the image is taken. The presence or absence of self-decomposition propagation property may be confirmed.
更に、ビデオカメラの撮像における分解火炎の移動距離とその時間から自己分解伝播速度を求める。この時、高速度ビデオカメラを用いて行うのが好ましい。この方法によって精度良く自己分解伝播速度を求めることができる。 Furthermore, the self-decomposition propagation velocity is obtained from the moving distance and time of the decomposition flame in video camera imaging. At this time, it is preferable to use a high-speed video camera. By this method, the self-decomposition propagation velocity can be obtained with high accuracy.
