Abstract
The invention provides a non-contact method for dehumidifying liquid and a dehumidifier. The method comprises the following steps that: dehumidifying saline solution and air are separated by a membrane; when the air flows from the surface on one side of the membrane, water vapor in the air passes through the membrane selectively to reach the other side of the membrane; and then, the water vapor is absorbed by the dehumidifying saline solution contacted with the membrane, but salt molecules and liquid water cannot pass through the membrane so as to dry the air. The dehumidifier comprises a shell, an air passage and a saline solution passage, wherein the air passage and the saline solution passage are separated by the membrane; and the membrane is placed in the shell, and is a permselective membrane, so that the water vapor can pass through the membrane but the saline solution cannot pass through the membrane. The method and the dehumidifier can effectively prevent salt in the solution from being brought into the air, thereby preventing occurrence of corrosion.
