Operation includes: to close absorption valve, opens desorption valve, and the stripping gas that sieve adsorpting bed A comes out enters light after cooler condenses
Wine tank opens vacuum line stop valve K9, system is controlled to a vacuum pump after pressure is gradually decreased to normal pressure, further removes
Absorption water in molecular sieve after reaching requirement, closes vacuum line stop valve K9, system and vacuum pump is disconnected.
10. it is according to claim 8 production absolute alcohol power-economizing method, it is characterised in that: sieve adsorpting bed A and point
The part absolute alcohol steam come out after son sieve adsorbent bed B dehydration, enters two molecular sieves after superheater heats from top to bottom and inhales
Attached bed is rinsed, and rinses gas after condenser condenses, into light wine tank, the light wine in light wine tank is pumped to rectifying work through light wine
