Device for subcooling low-boiling liquefied gases

摘要

Apparatus for subcooling low - boiling liquefied gases, comprising an insulated container (3) for receiving a cooling bath (10) fed from a low pressure partial stream of a low - boiling liquefied gas withdrawn from a reservoir (6), and means (24) for Discharge of the gas phase from the insulated container (3), and a means for regulating the liquid level in the cooling bath (10), further comprising a with the reservoir (6) flow-connected outlet line (5, 9) is provided for the to be cooled low-boiling liquid, the with a device (4) for heat transfer from the under-cooling low-boiling liquid in the outlet (5, 9) on the cooling bath (10) is flow-connected, characterized in that for the purpose of feeding the cooling bath (10) a plurality of with the reservoir (6 ) flow-connected, in each case with a blocking fitting (16, 17, 18, 19) equipped supply lines (1 2, 13, 14, 15) in the insulated container (3), each of the locking fittings (16, 17, 18, 19) with a device for detecting the filling height of the cooling bath (10) is operatively connected such that the locking device ( 16, 17, 18, 19) when falling below a predetermined Grenzfüllhöhe the respective supply line (12, 13, 14, 15) opens, but closes when exceeding the Grenzfüllhöhe, wherein for at least two leads (12, 13, 14, 15) each different Grenzfüllhöhen are given.
