Problems solved by technology

A typical method of gathering ocean energy is wave energy or tidal energy, which uses tapered channels to send seawater to a certain height to form a potential difference. However, using this method to increase the height of seawater is limited, so only relying on flow The method of improving the potential energy of seawater by the channel structure is far from enough, because the pressure difference is not large, its efficiency is often relatively low, and it is not easy to use

Embodiment Construction

[0107]A method of seawater desalination and power generation driven by tidal energy. Firstly, a storage tank is built on the seashore, and the high-level seawater in the sea is used to impact the rotation of the water turbine and / or store water after ebb tide when the high tide flows into the storage tank. The high-level seawater in the pool impacts the water turbine to rotate in the process of flowing to the sea. The water turbine drives the high-pressure pump through the gearbox to generate high-pressure seawater. The high-pressure seawater first flows through the reverse osmosis membrane module to produce fresh water. About 60% of the original seawater, the concentrated seawater at this time still maintains high pressure, and the high-pressure concentrated seawater discharged from the reverse osmosis membrane module flows through the turbine and impacts the turbine to rotate, and the turbine drives the generator to generate electricity to realize the comprehensive utilization...

Abstract

The invention discloses a bypass booster type seat water desalination and power generation device utilizing tidal energy for two-way drive. The device comprises a water storage tank, a first water turbine, a second water turbine, a transmission box, a gear box, a high pressure pump, a reverse osmosis membrane assembly, a booster pump, a turbine motor, a generator and a motor. The device impacts the first water turbine and the second water turbine to rotate respectively in the process that high level seawater in the sea in a rising tide flows into the water storage tank and in the process that high level seawater in the water storage tank in an ebb tide flows to the sea, utilizes the gear box to drive the high pressure pump to work to produce high pressure seawater and utilizes the booster pump to form booster bypass stabilizing system water pressure. High pressure dense seawater discharged from the reverse osmosis membrane assembly impacts the turbine motor to rotate, and the turbine motor drives the generator to rotate to produce electric energy to achieve comprehensive utilization and conversion of tidal energy. A system does not require additional power and is low in operation cost. The tidal energy is a renewable energy source, has sustainable development performance and has good social value and application value.

Description

[0001] This application is a divisional application with a filing date of December 4, 2010 in China, application number 2010105815528, and a divisional application titled "Method and device for seawater desalination and power generation driven by tidal energy". technical field [0002] The invention relates to a seawater desalination and power generation device, in particular to a seawater desalination and power generation device driven by tidal energy. Background technique [0003] Water is an important substance for the survival of human beings and all living things. The earth has sufficient water resources. The total amount of water reaches 1.4 billion cubic kilometers. However, there are very few fresh water resources that can be used by human beings, and the reserves only account for the total amount of water in the world. 2.53% of the total, and 68.7% of the fresh water exists in the form of solid glaciers, which are difficult to exploit. The only fresh water that h...
