The suction unit 120 is made of a material through which water vapor can pass, and the fluid introduced from the inlet unit 110 is formed to be lower than the external atmospheric pressure, so that the steam can be collected. This is because the pressure of the fluid flowing through the suction unit 120 is lower than the pressure of the air flowing through the suction unit 120, so that an air flow from the outside to the inside of the suction unit 120 is generated due to the pressure difference. In addition, since the suction unit 120 is made of a material through which water vapor can pass selectively, only water vapor flows in the material constituting the air, and the air introduced into the suction unit 120 flows into the inside And flows to the discharge portion 130 together with the fluid.

Alternatively, the plurality of membranes 100 and the plurality of membrane modules 200 may be controlled to selectively control the flow of the fluid or the valve 30 connected to the selected membrane or membrane module to maintain the dehumidification level.

The membrane 100 of the present invention may be formed of a polysulfone hollow fiber membrane and may be formed by coating a polyamide layer with a thickness of 100 nm to 200 nm in order to increase the selectivity of water vapor in the air.

Also, the inner hollow portion of the membrane 100 may include a circular tube, and may be formed in various shapes such as a round triangle, a rounded corner, a triangle, and a square.

The membrane 100 may be formed of a very thin film having a thickness of about 0.5 mm to 1.2 mm through which water vapor can be structurally structured, but the present invention is not limited thereto.

The membrane 100 having the above structure has the effect of minimizing leakage and evenly distributing the water vapor penetrated into the membrane 100. Further, the dehumidification performance of the membrane 100 having a small volume can be achieved with high efficiency.

In addition, the suction part 120 may be formed of a fine membrane made of a material such as chloroethylene, fluorocarbon tuffs and polyimide, have. At this time, the water vapor has a large polarity, and the solubility constant is larger than that of the molecule, and the permeation constant is also large, so that it can be separated faster than other components such as oxygen and nitrogen in the air. According to the present invention, a low-pressure fluid in the suction unit 120 flows on the basis of the nature of the water vapor, so that only water vapor in the air can be separated.
