Reverse osmosis well utilizing buoyancy and application thereof

Abstract

Belonging to the field of water treatment and seawater desalination, the invention discloses a reverse osmosis well utilizing buoyancy and application thereof. The reverse osmosis well provided by the invention utilizes buoyancy and other natural force, and consists of tubular objects. According to the relationship of depth and pressure, flow rate and differential pressure ratio, a conical supercharger is installed at the bottom end, the supercharger is in seal connection with an installed reverse osmosis module, the reverse osmosis module and a tube well are connected by a mechanical component, bonding or other means so as to fix the reverse osmosis module and no leakage exists between a membrane and the tube well wall of the reverse osmosis well, and the reverse osmosis module can have an anti-high pressure ability. By utilizing the natural pressure difference of the supercharger inside and outside the reverse osmosis well, seawater or to-be-treated water remains in a freshwater tube well of the reverse osmosis well through filtration of the reverse osmosis module, and then the freshwater is sent into a pipeline or a water holding device by a freshwater/purified water suction pipe. The water holding device can be a bucket, a palte, a basin and other utensils. Thus, the purpose of seawater desalination or pure water production can be realized.

Description

Technical field [0001] The invention discloses a reverse osmosis well using buoyancy and its use, belonging to the field of water treatment and seawater desalination. Background technique [0002] Among the 20 kinds of desalination technologies that have been developed, distillation, electrodialysis, and reverse osmosis have reached industrial scale production applications. They are all driven by energy consumption without exception. For example, the reverse osmosis seawater desalination and water filtration devices used therein rely on high-pressure water pumps to generate high pressure, so that the water has enough pressure to penetrate the reverse osmosis membrane. There is no report about reverse osmosis devices that fully utilize natural buoyancy. Summary of the invention [0003] The purpose of the present invention is to provide a reverse osmosis well that utilizes buoyancy, which is powered by the buoyancy generated by the reverse osmosis well itself in the water volume d...
