METHOD FOR PRODUCING WATER FROM AIR Russian patent published in 2017 - IPC E03B3/28 

FIELD: chemistry.

SUBSTANCE: method for producing water comprises using compressed air energy generators, cooling compressed air flow after generators in condensers with precipitation and moisture extraction. The compressed air energy generators are made in the form of membrane compressors, and the compressor membranes are made in the form of radially movable walls of vertical pipeline. The pipeline is provided with a float in the upper part, which ensures its positive buoyancy. The above-water part of the pipeline is equipped with a dart valve immediately stopping the relative movement of the pipeline and water in it when the valve is closed, thereby creating a hydraulic shock in the pipeline. The compressor membranes are driven by the energy of a hydraulic shock which occurs when the pipeline is vertically moved downward with the passage of a sea wave through the above-water part of the pipeline from ridge to depression. Air compression and injection are performed when a direct shock wave arises in the pipeline due to the closing of the dart valve. Absorption of atmospheric air is carried out by elastic forces of the membrane material when a backward rarefaction wave passes through the pipeline. A set of potential energy necessary for the occurrence of periodic hydraulic shock in the pipeline is carried out by vertical lifting of the pipeline to the height of the sea wave crest by the water buoyant force as the sea wave passes through the above-water part of the pipeline from the depression to the ridge.

EFFECT: reduced production cost of obtaining fresh water from moist sea air by using renewable energy of the sea wave.
