Tidal energy, solar energy, and mechanical vapor recompression integrated seawater desalination system

Abstract

The invention belongs to the technical field of seawater desalination, and especially relates to an integrated seawater desalination system, which utilizes the tidal energy and solar energy to generate power to drive a mechanical vapor recompression seawater desalination comprehensive utilization device to produce fresh water and refine salt-containing minerals. The system comprises a tidal energy power generation system, a solar energy power generation system, and an MVR evaporation system. The tidal energy power generation system is a tidal energy power station, which supply power to the system. The solar energy power generation system is a solar plate-type pre-heater, which can absorb the optical energy and convert the optical energy into electric energy and thermal energy, supplies power to the system, and preheats seawater in the pipes of the preheater. The MVR evaporation system is used to condense and desalinate the seawater.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a seawater desalination comprehensive system that drives a mechanical steam recompression seawater desalination comprehensive utilization device to realize power station power generation, fresh water production, and salt-containing mineral extraction through tidal power station power supply and solar power generation. Background technique [0002] Tidal energy and solar energy are clean, pollution-free, relatively stable and reliable renewable energy sources. China's long coastline stores abundant tidal energy, and its vast geographical area is rich in solar energy. my country's tidal energy power generation began in 1956. After decades of development, many large and medium-sized tidal energy power stations have been established, alleviating the power shortage of coastal areas and island residents in my country. The development of solar energy in my coun...

Problems solved by technology

There are three problems in the current seawater desalination system: First, the energy of traditional seawater desalination devices mainly comes from fossil fuels such as coal and oil, which consumes high energy and pollutes the environment. For islands, fossil fuels increase transportation costs; It is a traditional seawater desalination device, which directly discharges the concentrated seawater into the sea. If it goes on for a long time, it will affect the reproduction of animals and plants in the waters near the island, and cause direct economic losses to the mariculture near the island; the third is that the current seawater desalination technology lacks Integrity, the large amount of concentrated seawater produced is directly discharged, and has not been effectively utilized, and there is a lack of synergistic joint production and utilization with technologies such as saline mineral extraction
