WAVE CRYOGENERATORS APPLIED IN TECHNOLOGIES OF RARE GAS SEPARATION
The processes of gas refrigeration by an expansion method in turboexpanders are usually used in cryogenic installations. However, generators of cold have a complicated design and restrict application; it’s not possible to create safe efficient aggregates at little consumption. Therefore along with expansion machines, the apparatuses without a refrigerating plant are used. One of such perspective devices is a wave (resonance) cooler, the operation of which is based on thermal non-equilibrium state in the layer of pulsating gas. Now in cryogenic engineering, in particular in rare gas production jet signal generators are widespread. An arranged differential pressure given by limits of technological processes may be used as a drive mechanism. Incorporation of wave generators in the schemes of the installations for rare gas separation demands coordination of consumed characteristics of the apparatus with the main technological process. The authors have proposed an original design solution of a cooler with changeable geometry of the flow part without a refrigerating plant. The method of cooling in the Hartmann-Schprenger tube has been examined; it is of great scientific and practical interest. Impressive quantity of publications and patents is evidence of a wide range of applied problems that can be solved by means of wave cryogenerators in the field of refrigeration engineering, cryogenics, aviation and gas industry. Wave coolers fit successfully in global tendency of current technology that is perfection of safety of separate assemblies and the system as a whole at the expense of diminution of numbers of moving elements. Taking into account incontestable advantages of gas-dynamic apparatuses without refrigerating plants one can prognosticate with confidence their increasing role in cryotechnologies in future.
