FIELD: heating.
SUBSTANCE: gaseous helium cooling and cleaning device includes a cryostat, a liquid nitrogen level transmitter, a heat exchanger arranged in gaseous nitrogen environment, a heat exchanger placed in liquid nitrogen, a filter collecting frozen hazardous impurities, a helium electric heater and a nitrogen electric heater for regeneration of saturated filter. Device is equipped with two units installed in parallel after the filter, each of which includes an in-series located electropneumatic valve and a check valve. One unit is connected to the heat exchanger located in gaseous nitrogen environment and provided with two cavities, and the other one is connected to helium supply pipeline to the consumer after additional check valve installed after helium electric heater.
EFFECT: high cleaning quality of helium from hazardous impurities at provision of requirement for widening the temperature range of the environment and tanks filled with cryogenic fuel components.
