Device for carrying out gas production and gas injection by utilizing wave force to hoist nutritive salt on seabed

Abstract

The invention relates to an artificial upwelling device and aims to provide a device for carrying out gas production and gas injection by utilizing a wave force to hoist nutritive salt on a seabed. The device carrying out gas production and gas injection to hoist the nutritive salt on the seabed comprises a guide rail mechanism, a floating mechanism, a gas collecting mechanism, a gas conveying pipe and an upwelling mechanism; the floating mechanism is embedded on the guide rail mechanism; the gas collecting mechanism is fixed inside the guide rail mechanism; and the upwelling mechanism is connected with the gas collecting mechanism by the gas conveying pipe. The device directly utilizes fluctuation of waves to carry out gas collection and gas injection and utilizes wave energy to replace other forms of energy supplied by the ground, so that energy is effectively saved; an adopted gas injection hoisting method has high efficiency, a large upwelling ratio (i.e. a ratio of upwelling liquid flow to gas injection flow) and higher efficiency; and moreover, the device adopts the simple mechanisms, is low in cost and is very convenient to install and lay out.

Description

technical field [0001] The invention relates to an artificial upwelling device, in particular to a device for raising nutrient salts on the seabed by gas extraction and gas injection using wave force. Background technique [0002] Ocean upwelling is an important factor supporting fishery production, which is conducive to restoring the marine ecological environment and improving marine productivity. Nutrients are abundant in deep seawater, if they can be brought into the photic layer of the ocean, they will be ingested by phytoplankton, together with dissolved carbon dioxide and solar energy, organic matter can be produced through photosynthesis and rise to the photic layer Nutrients such as nitrogen and phosphorus can be converted to zooplankton and fish. Upwelling areas usually have higher primary productivity than other sea areas, and sea areas with significant upwelling are mostly famous fishing grounds. According to statistics, the upwelling sea area accounts for about...
