Abstract
A cryogenic system adapted to trap or pump waste industrial gasses and characterized by a cryogenic assembly having a cryogenically cooled member sealed within an inner enclosure, a thermal switch assembly for injecting and removing gas from within the inner enclosure, and a flush assembly for removing the solid and liquid residues of the industrial gasses from the trap assembly. The inner enclosure may be covered with a sacrificial material such as copper to chemically react with the reactive gasses. The use of a thermal switch assembly permits rapid regeneration of the system because the cryogenically cooled member does not have to be shut down during the regeneration cycle.
Claims8
A cryogenic system comprising:
- a cryogenic assembly including:
- refrigeration means having a cold member capable of being chilled to cryogenic temperatures;
- an inner enclosure surrounding said cold member to provide a sealable inner chamber with said cold member within, said inner enclosure being provided with orifice means;
- and
- an outer enclosure surrounding said inner enclosure to provide a sealable outer chamber, said outer enclosure being provided with an inlet and an outlet communicating with said outer chamber;
- thermal switch means including:
- a source of thermally conductive fluid;
- and
- means for selectively injecting and removing said thermally conductive fluid into and out of said inner chamber through said orifice means;
- and
- flush means including:
- a source of flush fluid;
- and
- means coupling said source of flush fluid to said inlet of said outer enclosure.
