The utility model belongs to the technical field of gas separation, in particular to a device for separating water vapor from moist air. The device of the utility model includes: a filter, a blower, a composite membrane separator, a compressor, a condenser, some control valves and necessary pipelines. The moisture-containing raw air first enters the filter to filter out the particulate matter, and then is sent to the composite membrane separator through the blower. The low partial pressure water vapor first contacts the composite membrane adsorption layer and will be adsorbed and enriched. Under the action of preferentially passing through the membrane separator, the output is water vapor through the compressor outlet, and the liquid water can be obtained continuously and efficiently through the condensation technology, while the lean water vapor is discharged from the stagnant side of the membrane separator to the outside of the system. Compared with the simple membrane separation method, the simple adsorption separation method, or the direct compression method, the utility model has higher efficiency, and the separation process can be carried out continuously. |
