Abstract

The invention discloses an air acquisition device and method from water, which comprises the following parts: depression device 1, gas collection, storage and discharge device 2 and valve control structure 3, wherein the depression device 1 interconnects the gas collection, storage and discharge device 2 through gas-water separation unidirectional valve 12; the valve control structure 3 is set between the case 22 and depression device 1. The method comprises the following steps: first, adapting one sealing water depression device 1; second, proceeding the gas-water separation of evolved gas-water mixture through depression device 1; collecting the gas; third, purifying the collected gas; supplying the gas for operator. The invention saves heavy oxygen bottle, which doesn't limit the time for underwater operator and reduces the cost.

Description

technical field [0001] The present invention relates to a device and method for obtaining air from water. Background technique [0002] At present, foreign research on obtaining oxygen from water mainly adopts artificial gills to obtain oxygen from water. This technology was invented in the 1960s and has a history of 30 years. In 1964, American W.L.Robb developed a method of obtaining oxygen from seawater by using artificial gills made of silicone rubber membranes. This membrane allows dissolved oxygen in seawater to pass through smoothly, while water cannot pass through. The inventor's purpose is to provide submarines with oxygen. In 1967, C V Paganell and others used a different hydrophobic porous membrane instead of silicone rubber to make artificial gills. They used this artificial gill device to extract dissolved oxygen from water for the baby to breathe. They believe that this device can make people watch fish in the Niagara River. In 1987, the American Membrane Te...
