Device for generating power and desalinating seawater by using tidal energy

Abstract

The invention discloses a device for generating power and desalinating seawater by using tidal energy, which is characterized in that tidal energy seawater and a tidal energy sea dam are fixedly connected with a U-shaped louver-type water inlet valve dam, the U-shaped louver-type water inlet valve dam and a U-shaped louver-type water drain valve dam form a closed buoyancy pool, a piston vessel is arranged in the center of the closed buoyancy pool and is movably connected with the closed buoyancy pool, the piston vessel is movably connected with a pool cylinder sleeve through a piston and a piston ring, the bottom of the closed buoyancy pool with the pool cylinder sleeve inside is fixedly connected with the pool cylinder sleeve through a pool cylinder sleeve water inlet valve and a pool cylinder sleeve water inlet and drain passage, the pool cylinder sleeve is fixedly connected with a high-pressure water conservation reservoir through a high-pressure water inlet valve and a high-pressure water inlet passage, the high-pressure water conservation reservoir is fixedly connected with a power generator set or a seawater desalinating device through a water diversion pipe, and the U-shaped louver-type water drain valve dam with a louver-type valve inside is connected with the sea. The device can convert tidal energy into power for desalinating seawater through buoyancy, gravity, pressure and hydraulic power, not only has a simple structure and is safe and reliable, but also is economical and practical, has long-term benefits and realizes sustainable development of renewable energy.

Description

technical field [0001] The invention mainly relates to a kind of marine resource and the field of renewable energy development. In particular, a device that uses tidal energy to generate electricity and desalinate seawater. Background technique [0002] At present, electric energy and fresh water are indispensable and commonly used energy for human beings, and clean renewable energy is the most ideal energy for human beings to pursue. Existing electric energy is mainly supplied by hydropower, thermal power, solar energy, wind energy, nuclear power and other power stations, all of which have many advantages and disadvantages: Although hydropower generates a large amount of power, it is affected by a large number of immigrants, earthquakes, and war consequences. Thermal power plants consume a lot of coal and emit a lot of carbon dioxide. Although solar energy and wind power are clean, there is no sunlight. The wind power is too small and the power is unstable and the power ...

Problems solved by technology

The existing electric energy is mainly supplied by power stations such as hydropower, thermal power, solar energy, wind energy, and nuclear energy. They all have many advantages and disadvantages: Although hydropower generates a large amount of electricity, it is affected by a large number of immigrants, earthquakes, and war consequences.

Seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, and reverse osmosis method. At present, the reverse osmosis method using reverse osmosis membrane quickly occupies the market due to its advantages of simple equipment, easy maintenance and equipment modularization, and gradually replaces distillation. The most widely used method, but the cost of using expensive high-pressure water pumps, pumping equipment and per ton of desalinated seawater consumes two or three kilowatt-hours of electricity, and correspondingly emits a large amount of carbon dioxide
