Beschreibung
Zusammenfassung:	A preparation apparatus for anhydrous alcohol comprises an adsorber I (5) which possesses a molecular sieve adsorption membrane and performs adsorption dewatering on common-level alcohol, an adsorber II (6) which possesses a molecular sieve adsorption membrane and performs desorption processing on the alcohol subjected to adsorption dewatering by the adsorber I (5), and an alcohol circular processing device which is arranged between the adsorber I (5) and the adsorber II (6) and processes the alcohol subjected to adsorption dewatering by the adsorber I (5) to obtain common-level alcohol; and through the adsorber I (5), common-level alcohol is processed to obtain anhydrous alcohol, and through the adsorber II (6) and the alcohol circular processing device, the alcohol subjected to adsorption dewatering by the adsorber I (5) is processed to obtain common-level alcohol, and thus the preparation apparatus does not only comprise processing from common-level alcohol to anhydrous alcohol again. The anhydrous alcohol forming process is cycled, and the efficiency of preparing anhydrous alcohol is improved.
