GAS DRYER
This gas dryer includes: a first drying tower having a first desiccant provided therein; and a second drying tower having a second desiccant provided therein. Either the first drying tower or the second drying tower is switched to a drying circuit side for drying hydrogen gas of an electric device, and another of the first drying tower or the second drying tower is switched to a reactivation circuit side for reactivating the first desiccant or the second desiccant provided therein. The gas dryer includes a cooler which is provided on the reactivation circuit side and which, with only supply of compressed air, generates air having such a temperature that can condense moisture in the gas on the reactivation circuit side.
1 . A gas dryer for drying hydrogen gas of an electric device in which the hydrogen gas is sealed, the gas dryer comprising:
a first drying tower having a first desiccant provided therein; and
a second drying tower having a second desiccant provided therein, wherein
either the first drying tower or the second drying tower is switched to a drying circuit side for drying the hydrogen gas of the electric device, and another of the first drying tower or the second drying tower is switched to a reactivation circuit side for reactivating the first desiccant or the second desiccant provided therein, and
the gas dryer includes a cooler which is provided on the reactivation circuit side and which, by a vortex principle using compressed air, generates air having a temperature of which a maximum temperature difference from the compressed air is −75° C. and which enables condensation of moisture in the hydrogen gas on the reactivation circuit side, thus cooling the hydrogen gas, and
the cooler is provided with an air compressor for supplying the compressed air.
