Adiabatic collector for recycling gas, liquefier for recycling gas, and recovery apparatus for recycling gas using same

A liquefier for recycling gas, the liquefier comprising:

• a non-mechanical (NM) compressor which when supplied with recycling gas in an adiabatic state, non-mechanically compresses the recycling gas by using a pressure difference caused by thermal expansion of the recycling gas, and then supplies the recycling gas in a liquid state;
• a dewar in fluid communication with the NM compressor, providing a storage space for storing the recycling gas in the liquid state, and having an opening provided at a side of the dewar so as to discharge the recycling gas in the liquid state through the opening;
• a cold finger protruding into the storage space after penetrating the dewar for liquefying the recycling gas by coming into contact with the recycling gas supplied from the NM compressor in a cryogenic state;
• a refrigerator for cooling the cold finger into a cryogenic state;
• a compressor for supplying refrigerant to the refrigerator;
• and
• a chiller for cooling the compressor,
• wherein, the NM compressor includes:
• an expansion chamber supplied with the recycling gas in the adiabatic state, changing the supplied recycling gas into high pressure recycling gas by supplying thermal energy thereto, and providing an expansion space for the recycling gas,
• a discharge valve in fluid communication with the expansion chamber and the dewar, and via which the high pressure recycling gas can be discharged into the dewar using a pressure difference between the recycling gas in the expansion chamber and the recycling gas in the dewar,
• an inflow valve in fluid communication with an inlet of the expansion chamber and a buffer container so as to allow the recycling gas to flow into the expansion chamber from the buffer container under influence of a pressure differential between the buffer container and the expansion chamber
• a liquefying tank forming the storage space;
• a first vacuum jacket forming a vacuum space along an outer surface of the liquefying tank so as to prevent heat loss from the liquefying tank;
• a refrigerant jacket forming a cooling space along an outer surface of the first vacuum jacket in which space the refrigerant can flow;
• and
• a second vacuum jacket forming a vacuum space along an outer surface of the refrigerant jacket so as to prevent heat loss from the refrigerant jacket;
• a purification jacket between the refrigerant jacket and the second vacuum jacket, the purification jacket having a first end in fluid communication with the discharge valve of the NM compressor and a second end in fluid communication with the liquefying tank, the purification jacket configured to effect a pre-cooling of the recycling gas by using coldness of the refrigerant jacket by routing the recycling gas from the NM compressor along the outer surface of the refrigerant jacket and to condense impurities in the recycling gas.
