Description
Известно, что при сжижении газов детандирование более эффективно , чем дросселирование. В известных схемах с детандерами получение холода на самом низком температурном уровне, включа сжижение , происходит за счет дросселировани . Объ сн етс это тем, что в этой области детандер мало эффективен и, кроме того, осуществление ожижительной машины, в которой выдел етс жидкость, представл ет значительные технические трудности. В схемах с детандерами стрем тс увеличить долю газа, подаваемого в детандер, однако этому преп тствует уменьшение разности температур в теплообменнике.It is known that during gas liquefaction, expansion is more effective than throttling. In the known circuits with expanders, getting cold at the lowest temperature level, including liquefaction, occurs due to throttling. This is explained by the fact that in this area the expander is not very effective and, in addition, the implementation of a fluidizing machine in which liquid is released presents considerable technical difficulties. In schemes with expanders, the proportion of gas supplied to the expander tends to increase, but this is prevented by a decrease in the temperature difference in the heat exchanger.
Предлагаемый способ сжижени водорода путем глубокого охлаждени и сжати при высоком давлении по сравнению с известными аналогичными способами позвол ет снизить расход энергии и повысить процент сжижени газа. Этого достигают тем, что водород сначала охлаждают, подвергают расширению в детандере и затем дросселируют; водород перед дросселированием может быть охлажден неожнженной частью водорода.The proposed method of hydrogen liquefaction by deep cooling and compression at high pressure, in comparison with known similar methods, allows to reduce energy consumption and increase the percentage of gas liquefaction. This is achieved by first cooling the hydrogen, expanding it in an expander, and then throttling it; hydrogen before throttling can be cooled by an unbounded part of hydrogen.
На фиг. 1 и 2 приведены схемы сжижени водорода, по сн юш,ие осуш,ествление предлагаемого способа.FIG. Figures 1 and 2 show hydrogen liquefaction schemes, have been dried, and dried, the design of the proposed method.
Водород высокого давлени проходит через теплообменник 1 холодной зоны, поступает в детандер 2, где расшир етс до промежуточного давлени , затем дросселируетс в сборнике 3, откуда неожиженна часть водорода пропускаетс через теплообменник 1 (позицией 4 обозначен дроссельный вентиль, позицией 5 - ресивер). По этой схеме детандер легко включаетс в существующие ожижительные машины с дросселированием, с повышением их холодопроизводительности приблизительно на 40%.The high pressure hydrogen passes through the heat exchanger 1 of the cold zone, enters the expander 2, where it expands to intermediate pressure, then is throttled in the collector 3, from where the non-liquefied portion of hydrogen is passed through the heat exchanger 1 (position 4 denotes the throttle valve, position 5 the receiver). According to this scheme, the expander is easily incorporated into existing fluidizing machines with throttling, with an increase in their cooling capacity of approximately 40%.
Согласно другой схеме (фиг. 2) между детандером и дроссельным вентилем устанавливаетс дополнительный теплообменник 6, что дает некоторое дальнейшее снижение расхода энергии.According to another scheme (Fig. 2), an additional heat exchanger 6 is installed between the expander and the throttle valve, which gives some further reduction in energy consumption.
