低温液体供气系统

Cryogenic Iiquid air-supply system

对低温液体（液氮、液氩、液氧）供气系统的工作原理、贮存运输优越性、低温液体贮槽、气化器以及供气系统做了介绍。低温液体贮运具有效率高、供气质量好、压力稳定、成本低、使用安全以及洪气快速简便等优点。适用于电子工业、机械加工行业大量使用高纯氮气、氩气做保护气体。液氧经气化后由供气系统供给无任何污染的纯氧气代替工业氧气钢瓶为医院病员提供干净的呼吸氧气。

The operating principle of the cryogenic liquid(liquid nitr ogen,liquid argon and liquid oxygen)air-supply systetn has been introduced in this paper,The advantage of storage and transport.cryogenic liquid tank,evaporatorand air-supply systeln have been described. The storage and transport of cryogenic liquid have several advantages such as high efficiencv,stable pressure,low cost,safe use and quick,simple air-supply etc,This svstem can be used in electronic industry and machining which use a great quantity of highly pure nitrogen,argon as protective gases.After evaporation of liquid oxygen,the air-supply system will offer pure oxygen without any pollution。Instead of industry oxygen bottle and provide patients with clean respiratory oxygen.
