Description
【０００１】[0001]
本考案は、高純度の炭酸ガスを使用する設備での炭酸ガス供給装置に関する。 The present invention relates to a carbon dioxide gas supply device in a facility that uses high purity carbon dioxide gas.
【０００２】[0002]
従来、高純度の炭酸ガスを必要とする場合、図２に示すように、液化炭酸ガス 貯蔵容器(51)と気化器(52)とで構成し、気化器(52)から導出した気体炭酸ガス導 出路(53)にガス減圧弁(54)を配置し、液体状態で貯蔵容器(51)から導出した炭酸 ガスを気化器(52)で気体に相変化させ、気化器(52)から導出された気体炭酸ガス をガス減圧弁で減圧して使用設備で使用するようにしていた。 Conventionally, when high-purity carbon dioxide gas is required, as shown in FIG. 2, it is composed of a liquefied carbon dioxide gas storage container (51) and a vaporizer (52), and is a gaseous carbon dioxide gas derived from the vaporizer (52). A gas pressure reducing valve (54) is arranged in the discharge path (53), and carbon dioxide gas, which is discharged from the storage container (51) in a liquid state, is phase-changed into a gas in the vaporizer (52) and is discharged from the vaporizer (52). The gas carbon dioxide gas was decompressed by the gas pressure reducing valve and used in the facility.
【０００３】[0003]
ところが、従来の炭酸ガス供給装置では、炭酸ガス貯蔵容器から気体導出路に 配置したガス減圧弁までの間がゲージ圧力１０Kg／cm2以上の圧力となることか ら、気化器自体も１０Kg／cm2・Ｇ以上の圧力に耐えられる構造が必要となり、熱 交換効率が悪く、気化器(熱交換器)自体が大型になるという問題があった。 本考案は、このような点に着目してなされたもので、気化器を小型に形成する ことのできる炭酸ガス供給装置を提供することを目的とする。However, in the conventional carbon dioxide gas supply device, the gauge pressure from the carbon dioxide storage container to the gas pressure reducing valve arranged in the gas outlet is 10 kg / cm 2 or more, so the vaporizer itself is 10 kg / cm 2. A structure that can withstand a pressure of 2 G or more is required, heat exchange efficiency is poor, and the vaporizer (heat exchanger) itself becomes large. The present invention has been made paying attention to such a point, and an object thereof is to provide a carbon dioxide gas supply device capable of forming a small vaporizer.

上述の目的を達成するために本考案は、液化ガス貯蔵容器と気化器の入り口と の間の液化ガス導出路に液減圧弁を配置し、この液減圧弁を気化器から導出した 気体導出路のガス減圧弁よりも気化器側に配設した圧力指示調節器からの指示に 基づき減圧調整するように構成したことを特徴としている。 In order to achieve the above-mentioned object, the present invention has a liquid decompression valve disposed in a liquefied gas discharge passage between a liquefied gas storage container and an inlet of a vaporizer, and the liquid decompression valve is led out from the vaporizer. It is characterized in that the pressure is reduced and adjusted based on an instruction from a pressure instruction controller arranged on the carburetor side of the gas pressure reducing valve.

本考案では、液化ガス貯蔵容器と気化器の入り口との間の液化ガス導出路に液 減圧弁を配置し、この液減圧弁を気化器から導出した気体導出路のガス減圧弁よ りも気化器側に配設した圧力指示調節器からの指示に基づき減圧調整するように 構成しているので、気化器に流入する液化炭酸ガスは液減圧弁の設定圧に減圧さ れ、その保有熱量が小さく、少ない入熱量でも確実に気化できることになる。 In the present invention, a liquid pressure reducing valve is arranged in the liquefied gas outlet passage between the liquefied gas storage container and the inlet of the vaporizer, and the liquid pressure reducing valve is vaporized more than the gas pressure reducing valve in the gas outlet passage led from the vaporizer. Since the decompression is adjusted based on the instruction from the pressure indication controller installed on the side of the vaporizer, the liquefied carbon dioxide gas flowing into the vaporizer is reduced to the set pressure of the liquid decompression valve, and the amount of heat retained is retained. It is small and can be surely vaporized even with a small heat input.
