本考案は低温液化ガスの減圧取り出し装置に関

から水分や炭酸ガス等が分離されるようにしてい
る。(Prior art) In order to remove moisture, carbon dioxide, etc. contained in gas such as air used in conventional vacuum equipment, the air is passed through a cold trap 1 as shown in Fig. 2. A low-temperature liquid nitrogen tank 2 is placed in the cold trap 1, and liquid nitrogen is supplied from the liquid nitrogen storage tank 3 into the tank 2 to exchange heat with the air to lower the temperature of the air. Water, carbon dioxide, etc. are separated from the water.

器１１を通じてガスとして他用途に使われている
場合が多く、一般に液体窒素貯槽３内の液体窒素
の圧力は７Kg／cm2と高く、このためこれを減圧し
て供給する必要がある。 In such a device, it is preferable that the liquid nitrogen tank 2 placed inside the cold trap 1 be made of a thin metal plate to improve heat exchange, but the liquid nitrogen is used for other purposes as a gas through an evaporator 11. In many cases, the pressure of liquid nitrogen in the liquid nitrogen storage tank 3 is generally as high as 7 kg/cm 2 , and therefore it is necessary to reduce the pressure and supply it.
又供給液化ガスの圧力が高いと液化ガスが高圧
のため吹き飛ばされこれを槽２内に溜めることが
できないことが多い。 Further, when the pressure of the supplied liquefied gas is high, the liquefied gas is often blown away due to the high pressure and cannot be stored in the tank 2.
このため従来装置では高圧の貯槽３とコールド
トラツプ１内の槽２間の配管に実公昭57−6944号
公報に示すような気液分離器４を介挿し液体窒素
の圧力を0.5〜１Kg／cm2に低下せしめている。 For this reason, in the conventional device, a gas-liquid separator 4 as shown in Japanese Utility Model Publication No. 57-6944 is inserted in the piping between the high-pressure storage tank 3 and the tank 2 in the cold trap 1, and the pressure of liquid nitrogen is increased from 0.5 to 1 kg/kg. cm2 .
尚５は電磁弁、６は液面センサーである。 Note that 5 is a solenoid valve, and 6 is a liquid level sensor.
然しながらこのような装置では下記のような欠
点がある。 However, such a device has the following drawbacks.
(1) 設備費が非常に高くつく。(1) Equipment costs are very high.
(2) 気液分離装置にも液体窒素センサーを取り付
けて液面制御をしなければならない。(2) A liquid nitrogen sensor must also be installed in the gas-liquid separator to control the liquid level.
(3) トラブル発生の原因となる個所が多くなる。(3) The number of points that can cause trouble increases.
(4) トラツプ槽の強度を高めなければならない。(4) The strength of the trap tank must be increased.
（考案の目的）
本考案の目的は上記のような欠点を除去した低
温液化ガスの減圧取り出し装置を得るにある。(Object of the invention) The object of the invention is to obtain a reduced pressure extraction device for low temperature liquefied gas which eliminates the above-mentioned drawbacks.
（考案の構成）

特徴とする。(Structure of the invention) The low-temperature liquefied gas depressurization extraction device of the present invention has a vacuum between a high-pressure liquefied nitrogen supply source and a low-pressure side pipe with a diameter larger than that of the above-mentioned pipe filled with a water-permeable filler and a desired length. A pipe is inserted therein, and a gas-liquid separation filter is provided at the outlet of the low-pressure side of the pressure reducing pipe.

はグラスウール等の長手方向に通水性のある通路
が形成される充填材７を充填した、配管より十分
大径で且つ十分な長さを有する減圧管８を用い
る。(Embodiment of the invention) In the present invention, instead of using the gas-liquid separator 4 as shown in FIG. 1, a filler material having water-permeable passages in the longitudinal direction such as asbestos, beads, or glass wool is used inside the gas-liquid separator 4. A pressure reducing pipe 8 filled with 7 is used and has a diameter sufficiently larger than that of the pipe and a sufficient length.
尚９は減圧管８の両端開口に設けた穴あき蓋
体、１０は配管途中から侵入した熱によりできた
ガスを液体より分離する焼結フイルターである。 Note that 9 is a perforated lid provided at both ends of the pressure reducing tube 8, and 10 is a sintered filter that separates gas generated by heat entering from the middle of the pipe from liquid.
本考案の低温液化ガスの減圧取り出し装置は上

流量を損なうことなく通路抵抗による圧力の低下
のみを達成することができ、低温液化ガスを所望
の圧力に減圧することができる。 Since the low-temperature liquefied gas vacuum extraction device of the present invention has the above-described configuration, when the low-temperature, high-pressure liquefied gas passes through the pressure reducing pipe 8, the liquefied gas flows through a large number of mutually parallel lines formed by the filler 7; It will pass through a passage with a length of As a result, only the pressure reduction due to passage resistance can be achieved without impairing the overall flow rate, and the low temperature liquefied gas can be reduced to a desired pressure.
尚本考案における減圧管８の直径、長さ及び充
填材７の種類は用いる液化ガスの種類、圧力によ
つて種々異なるものとするのが好ましい。 In the present invention, it is preferable that the diameter and length of the pressure reducing tube 8 and the type of filler 7 vary depending on the type and pressure of the liquefied gas used.
（考案の効果）
上記のように本考案装置によれば極めて簡単な
構成により高圧の液化ガスを所望の低圧に減圧せ
しめ得る大きな利益がある。(Effects of the Invention) As described above, the device of the present invention has the great advantage of being able to reduce the pressure of high-pressure liquefied gas to a desired low pressure with an extremely simple configuration.
