Abstract
圧縮機33で圧縮した高圧の被液化ガスをアフタクーラ37で冷却し、被液化ガスの一部を膨張機(膨張タービン)28,29で断熱膨張させ、この膨張により得られた低圧低温ガスにより多段熱交換器22〜27を介して段階的に残りの被液化ガスを冷却し、この高圧ガスを断熱膨張させてガスの液化を行なう低温液化冷凍装置において、圧縮機33から排出される廃熱を動力源としたケミカル冷凍機(吸着冷凍機)38及びアンモニア冷凍機40を設け、アフタクーラ37の後段でかつ前記多段熱交換器の前段において高圧ガスを予冷する。
Description
図5は、特許文献1に開示されたヘリウム液化冷凍装置の系統図である。図5において、01は、外部からの熱侵入を防止するために真空に保持された保冷槽、02から06までは、保冷槽01内に配置された第1から第5までの熱交換器であり、07,08がそれぞれ第1及び第2膨張タービン、09がジュール・トムソン(JT)膨張弁、010が液体ヘリウム011を分離する気液分離器である。なお012は圧縮機(コンプレッサ)、013は高圧ライン、014は低圧ライン、015はタービンライン、016は液体窒素の冷却ラインである。
一方従来の液化冷凍装置においては、圧縮機から吐出された高圧常温の吐出ガスは、断熱のため真空に保持されたコールドボックスと呼ばれる保冷槽内に設けられた多段の熱交換器に導入される前に、液化冷凍装置の冷凍効率低下を防止するために、通常水冷式アフタクーラにより室温(常温)程度まで冷却された後、コールドボックスに入ることになる。
従って圧縮機の軸動力を低減することはできず、また圧縮機のモータ廃熱及び圧縮機から吐出される高温高圧ガスの顕熱が無駄に廃却されている。
即ち本発明は、高効率のケミカル冷凍機や蒸気圧縮式冷凍機を用いて圧縮機出口ガスを冷却することにより、低温の液化用ガスを圧縮機に吸入させ、もって圧縮機軸動力を低減させ、かつ液化冷凍効率を向上させることを目的とする。
必要に応じて、圧縮機吐出側の被液化ガスの一部を分岐させ膨張タービン等の膨張器を通して断熱膨張させることにより低温低圧ガスとし、その低温低圧ガスを気液分離器から圧縮機に戻る低温低圧ガスに供給することにより、低温低圧ガスを所望の温度に調整することができる。
また(c)においては、さらにアンモニア冷凍機40が設けられ、熱交換器39の後段の高圧ライン34に設けられた熱交換器41においてアンモニア冷凍機40で冷却した低温冷媒により高圧ガスをさらに冷却する構成となっている。図1中の数値は各工程での温度を示す。
そのため軸動力は、(a)の装置の100%に対し、(b)の装置が92%に、(c)の装置が85%に低減され、またヘリウムガスの冷却に要する熱交換器の段数も低減され、吸着冷凍機38及びアンモニア冷凍機40で圧縮機33の廃熱や軸動力を利用している点から装置の冷凍効率も向上している。
またコールドボックスの第1段熱交換器に供給される被液化ガスの温度を低減することができるため、被液化ガスの冷却に要する多段熱交換器の段数を低減させることができ、コンパクト化を達成できる。
また前記構成に加えて、ケミカル冷凍機で冷却された低温冷媒の一部を蒸気圧縮式冷凍機の凝縮器に凝縮用冷媒として供給するように構成し、同低温冷媒によって蒸気圧縮式冷凍機の凝縮温度を下げることで、凝縮工程時の圧力を低減して、同蒸気圧縮式冷凍機の冷凍効率を向上させることができる。

高圧ガスは、2次アフタクーラ55で冷却された後、精密オイルセパレータ64を経て、コールドボックスと呼ばれる保冷槽65に供給される。
圧縮機51の吐出側高圧ガスを1次アフタクーラ54で冷却した後、コールドボックス65に入る前に、2次アフタクーラ55で前記低温水によって高圧ガスを予冷することができるため、コールドボックス65に入る高圧ガスの温度を低減することができる。
また圧縮機51から排出される潤滑油が保有する熱を回収して吸着冷凍機61の駆動熱源としているため、装置全体の冷凍効果を向上することができる。
またアンモニア冷凍機92は、吸着冷凍機61の低温水の冷熱を凝縮用に利用しているため、装置全体としての冷凍効率を大幅に向上できる。
また装置効率FOM(1/成績係数COP;単位体積当りの圧縮機の所要動力)は、(a)の従来装置に比べて、(b)は約8%改善され、(c)は約11%改善されている。
またケミカル冷凍機105は、圧縮機101の軸動力から発生する潤滑油等の排熱を利用して駆動されるので、装置全体の冷凍効率を向上させることができる。
