Description

A device for raising seabed nutrients by gas production and gas injection using wave force

technical field

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. the

Background technique

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 0.1% of the world's ocean area, and its fish catch accounts for as much as 50% of the total amount of marine fish catch. the

The existing artificial upwelling technology is divided into two categories according to the implementation method: the first type is to transform the seabed topography to form artificial submarine mountains, and generate ocean upwelling under the action of ocean currents; the second type is to deploy artificial upwelling on the sea surface Flow devices such as water pumps, wave pumps, standpipes and gas injection lifting equipment, etc., pump nutrient-rich seawater from the deep ocean to the euphotic layer of the ocean to form upwelling. However, the disadvantage of the first method is that it will conflict with the future development of offshore oil, gas, mineral deposits and other resources; moreover, whether a large amount of building materials will be put into the seabed will pollute the marine environment remains to be further observed. In the existing solutions of the second type of method, the energy consumption of the water pump is large and the efficiency is low. Although the wave pump has a simple structure and low price, the flow rate is small. the

Professor Liang Naikang of National Taiwan University in my country applied the theory of air lift to the field of artificial upwelling research, pumping compressed air into a vertical pipe in the sea, using the mixture of air bubbles and water to be lighter than seawater, and the seawater rises under the action of the kinetic energy of bubble buoyancy The mechanism is to raise the seawater rich in high nutrients in the deep sea to the upper layer, so as to increase the productivity of the sea area, improve the environmental conditions of the sea area, and provide a set of feasible methods for marine aquaculture. However, domestically, there is no device that directly utilizes wave energy to inject gas to the seabed by means of sea surface devices. the
