Abstract

A method and an apparatus for desalinating sea water and generating with the sea energy resource. The method comprises: firstly collecting the sea surging energy by an energy collecting device, pressurizing the sea water with the collected energy by a sea water booster pump, producing the fresh water by inputting the sea water high pressure pipe to the sea water desalinating system; guiding the tail water with the high pressure after sea water desalination to a hydraulic generator for generating.

Description

technical field [0001] The invention belongs to the technology of using renewable ocean energy to desalinate seawater and generate electricity, in particular to a method and device for desalinating seawater and generating electricity by using ocean energy on the sea surface. Background technique [0002] Nowadays, seawater desalination itself is a relatively mature technology. Desalination and purification of seawater is not a technical problem for human beings, but reducing energy consumption is an urgent problem to be solved in seawater desalination. As we all know, seawater desalination is a resource industry to solve the shortage of fresh water. There are many production processes such as multi-stage flash evaporation, reverse osmosis, multi-effect evaporation and hydration. The common problem is that the production process consumes a lot of energy and the cost of fresh water is very high. Countries and regions with an average economic level and urgent need for fresh wa...
