Abstract

The application discloses an air water taking device based on gel water absorption and dehydration and application thereof. The device comprises a pipeline, pipeline supports, a long rod with a light-heat material on the surface and long plates with water absorption gel on the surface. The pipeline supports are arranged at two ends of the pipeline. The long rod is arranged in the pipeline and is coaxially arranged with the pipeline. The long plates are arranged at intervals. Compared with the traditional method, the air water taking device utilizes the water absorption gel and the light-heat material to create a temperature gradient and a concentration gradient in the longitudinal direction, so that efficient water collection is possible. The device can be applied to saline-alkali land and solves the technical problem of high energy consumption of the existing water taking device.
