This invention relates to an improvement in an argon purification device suitable for use in conjunction with a direct-boot gas separation device.

ンガスと合流する。Figure 1 is a system diagram of an argon purification device conventionally attached to and used in an air separation device. Crude argon (approximately 96% Ar) separated in the air separation device M10 is taken out through a conduit and compressed with argon. After being pressurized to a predetermined pressure in a machine 11 and cooled in an aftercooler 12, it is passed through a conduit. On the other hand, hydrogen gas generated in the hydrogen generator 13 and taken out through the conduit 21 is pressurized to a predetermined pressure by the hydrogen compressor 141, and then passes through the conduit 21 and merges with the crude argon gas flowing through the conduit 21. .

気分離装［１０に再び戻される。The combined crude argon gas and hydrogen gas become a mixed gas and are supplied to the catalyst tank 15 through conduit addition, where the oxygen and hydrogen gas in the crude argon gas react to form water, and the oxygen in the crude argon gas is removed. . The acid is supplied to a primary cooler 16 that is cooled with cooling water, for example, and after being cooled there, it is supplied through a conduit n to a secondary cooler 17, which is a Freon cooler, for example, where it is cooled to a predetermined temperature. After being dried, it is supplied to the dryer 18 through a conduit. The crude argon gas from which moisture has been completely removed in the dryer 18 is returned to the air separation device [10] via the conduit 6.

ストおよびメンテナンスコストが増大し経済性が低下す
ると共に、据付面積も広くなるといった欠点があった。In such argon purification equipment, the crude argon gas is pressurized to a predetermined pressure by the argon compressor, so if the pressure of the hydrogen gas generated from the hydrogen generator is low, the pressure will be higher than the discharge pressure of the argon compressor. The hydrogen gas produced by the hydrogen generator must be pressurized using a hydrogen compressor to achieve this. Therefore, it is necessary to install a hydrogen compressor and its peripheral equipment, which increases initial costs, running costs, and maintenance costs. There were drawbacks such as lower economic efficiency and larger installation area.
なお、水素圧縮機を設けずに、低圧のまま水素ガスをア
ルゴン圧縮機の吸入側に合流させることも考えられる。Note that it is also conceivable that the hydrogen gas is allowed to flow into the suction side of the argon compressor at a low pressure without providing a hydrogen compressor.
しかし、一般の圧縮機では水素ガスと酸素を含んだガス
の圧縮は、燃焼あるいは爆発を引起す恐れがあり危険で
ある。However, using a general compressor to compress a gas containing hydrogen gas and oxygen is dangerous as it may cause combustion or explosion.

これらに付随する制御方式も複雑となり、したがって価
格も高くなるという欠点がある。Furthermore, a known example of a special compressor is the so-called Natush compressor, which compresses gas containing hydrogen and oxygen by injecting water on the suction side of the compressor, but because it requires water injection, the water quality is poor. It is unsuitable for use in many locations, and the associated control systems, including the installation of a water and gas separator at the outlet of the Natsch compressor, are complex and, therefore, expensive.

In the catalyst tank 15, the oxygen and hydrogen gas in the crude argon gas react to form water, and at the same time as the oxygen is removed, the crude argon gas, whose temperature has risen to about 300°C due to the heat of reaction, passes through the conduit n to the primary cooler 16. supplied to

本実施例のようなアルゴン精製装置では、次のような効
果がある。The argon purification apparatus as in this embodiment has the following effects.
（１） アルゴン圧縮機の吸入側に水素ガスを導入させ
ることになるが触媒槽で水素は酸素と反応して水となる
ため、水素と酸素の混合ガスの圧縮はな４なり、燃焼あ
