Bypass booster type seat water desalination and power generation device utilizing tidal energy for two-way drive

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...

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
