A device and method for realizing subsea nutrient salt lifting by using the principle of inertial pump

Abstract

The invention relates to a device and a method for utilizing the principle of an inertia pump to realize lifting of subsea nutrient salts. The device comprises a heat collecting device, an inertia pump set, a deep-sea heat supplying device and a positioning device, wherein the heat collecting device is positioned on sea water and is used for collecting solar energy; the inertia pump set is communicated with the heat collecting device by a round sealing guiding rail; the deep-sea heat supplying device is communicated with the bottom end of the inertia pump set; the positioning device is used for fixing the relative positions of all inertia pumps. The device and method have the advantages that the principle of the inertia pump is utilized, the position of the inertia pump set is fixed by a positioning anchor chain and a positioning floater, the heat collecting device floats up and down along with waves, and the round sealing guiding rail fixed on the heat collecting device enables insulated metal pipes to slide in and out of the heat collecting device; the solar energy is absorbed for heating a water body, and the relative movement needed by operation of the inertia pumps can be realized by utilizing the wave energy, so that the energy is effectively saved and the green and environmental-friendly effects are achieved.

Description

technical field [0001] The invention belongs to the field of marine technical equipment, and relates to a device and a method for realizing the lifting of seabed nutrient salts by utilizing the principle of an inertial pump. Background technique [0002] Marine economy has become an important part of our national economy. After more than 50 years of development, my country's marine fishery has doubled the annual catch of aquatic products through technological progress, expansion of production sea areas and equipment renewal. The rich seafood has made a significant contribution to improving the living standards of our people. my country has a vast sea area, well-developed marine resources, and great potential for marine economic development. However, in recent years, due to the intensification of marine engineering activities, excessive discharge of land-based pollutants, and overfishing of offshore fishery resources, my country's offshore ecological environment has deterior...

Problems solved by technology

When working, since the two chambers of the thermal insulation water bladder are almost simultaneously compressed under the action of waves, it is equivalent to simultaneously pressurizing the thermal insulation conduits at both ends of the U-shaped heating device, so it is difficult to realize the circulation of the working fluid. The flow efficiency of working medium water in the insulation pipe is not high

Therefore, the energy utilization efficiency of the device is not high
