DMC dehydration device

The utility model relates to the technical field of dimethyl carbonate production, in particular to a DMC dehydration device which comprises a raw material storage tank, a concentrate storage tank is placed on the other side of the raw material storage tank, and the output end of the raw material storage tank is communicated with a dehydration assembly used for dehydrating DMC through a pipeline. The dehydration assembly comprises a heating part, a screening part, a penetrating fluid condensation part and a product condensation part, the heating part is communicated with the raw material storage tank, the screening part is communicated with the heating part, the penetrating fluid condensation part is communicated with a gas outlet of the screening part, and the product condensation part is communicated with a gas outlet of the product condensation part. Compared with a pressure swing adsorption dehydration process, the inorganic membrane dehydration adopted by the utility model does not generate light wine an
