Apparatus for containing toxic spills employing hybrid thermosyphons

摘要: The present invention is directed to a hybrid thermosyphon which may be rapidly deployed create frozen soil barrier for containing toxic spills. In particular embodiment, plurality of thermosyphons are freezing the around and under defined area soil; each contains working fluid includes an evaporator section contact with removing heat therefrom by evaporation fluid. A condenser in flow communication remote from transfers ambient exchange subsequent condensation when lower than temperature soil. An active refrigeration stage relation at least portion removes above temperature. Sensors provided sensing selectively operating stage.
