Abstract

一种低温汽轮机和一种反冲式液体汽轮机的联合循环运行装置。反冲式液体汽轮机的作用是把高压高温的液体通过反冲式液体汽轮机内的节流膨胀器绝热膨胀后，在低压容器内得到低温液体和气体，并且使气体的焓值减小。如用高压低温的液体氮在低温下吸热气化，并在更低的温度-195℃的状态下膨胀做功。得到-195℃的低温低压气体氮。用-220℃的高压液体氢去冷却-195℃的气体氮，并使氮气全部液化。得到高压-195℃的液体氢，并通过反冲式液体汽轮机内的节流膨胀器绝热膨胀，在低压容器内得到-250℃的液体氢和气体氢，用气体压缩机，把低压气体氢压缩至-220℃饱和压力的气体氢，把-250℃液体氢增压后去冷却-220℃的气体氢，并使其全部液化，以此完成低温汽轮机的整个循环运行。

Description

低温汽轮机及其循环装置
技术领域：本发明涉及的是一种低温汽轮机及其循环装置。
背景技术：低温汽轮机就是利用低温工质。如氨、氟利昂、乙烷、甲烷、氧、氮等物质，在常温或低温下，利用高压液体吸热气化得到低温高压气体，然后在更低的温度下膨胀做功的汽轮机，但由于低温低压气体无法液化，使低温汽轮机无法连续循环运行。
发明内容：针对上述缺陷，本发明解决了低温低压气体液化问题，使得低温汽轮机能够连续循环运行。
一种反冲式液体汽轮机，其作用是利用高温高压的液体通过反冲式液体气轮机内的节流膨胀器绝热膨胀后，在低压容器内得到低温低压的液体和气体，并且使气体的焓值减少。假设低压容器内气体的焓值仅为10％时，则低温汽轮机不但能够连续循环运行，并且能够向外界输送动能。假设低压容器内气体的焓值为50％时，则低温汽轮机仅能够连续循环运行，不能向外界输送动能。
具体实施方式：一假设高温高压液体通过反冲式液体汽轮机内的节流膨胀器绝热膨胀后，在低压容器内得到的气体的焓值为10％时，则用氨气汽轮机在常温至-33℃下的状态下循环，用甲烷气汽轮机在-33℃至-165℃的状态下循环，用氮气汽轮机在-165℃至-195℃的状态下循环，用-220℃的液体氢去冷却-195℃的氮气气体，得到-195℃的液体氢并交换热量Q。把-195℃的液体氢通过反冲式液体汽轮机在-220℃的状态下绝热膨胀，在低压容器内得至低温液体和气体，气体的焓值是10％Q，用-240℃的液体氦去冷却-220℃的气体氢得到-220℃的液体氦并交换热为10％Q，把-220℃的液体氦通过反冲式液体汽轮机内的节流膨胀器在-260℃的状态下绝热膨胀，得到-260℃的低温液体氦和气体氦气体的焓值为2×0.1Q×10％，把0.02Q焓值的氦气用制冷压缩机压缩至-240℃的饱和气体，用-260℃的液体氦去冷却-240℃的气体氦，交换热量0.1Q，并使气体氦液化，以此完成整个循环。
