Problems solved by technology

However, the concentrated seawater generated after seawater cooling is directly discharged back to the sea, which will affect the marine environment and waste concentrated seawater resources.
And it is difficult to build on a large scale in areas far from the coast where solar energy is abundant

Embodiment Construction

[0019] The embodiment is a set of equipment with a seawater tank, four modules and a salt drying field. figure 1 The process flow runs.

[0020] The bottom area of ​​the condenser is 1 square meter, the side length is 1 meter, the middle height is 0.1 meters, and the two sides are 0.08 meters high, such as Image 6 shown. The seawater ascending channel 1 is 0.98 meters long, 0.015 meters wide and 0.09 meters high, such as Figure 5 shown. The inlet of the fresh water outflow channel 2 is 0.02 meters away from the bottom surface. Photovoltaic modules cover the two slopes on the top surface of the condenser. The water-absorbing material cotton cloth is pasted on the lower surface of the photovoltaic module and reaches the seawater tank 6 under the bottom surface of the condenser along the inner wall of the water upward channel. The concentrated sea water tank 3 , the fresh water tank 4 , the condenser installation groove 5 and the sea water tank 6 are all fixed on the insta...

Abstract

According to the solar seawater electricity-water-salt co-production process and equipment provided by the invention, an overhead heating surface solar evaporation technology, a photovoltaic power generation technology and a traditional salt drying technology are integrated, the solar seawater electricity-water-salt co-production process is developed, and the whole set of equipment operated according to the process is designed. Seawater is adopted to cool the lower surface of the photovoltaic module, thereby reducing the temperature of the photovoltaic module and generating more power. And the generated steam is condensed into fresh water in the condenser. Concentrated seawater obtained by seawater concentration is used as a salt sunning raw material. And solar energy and seawater are fully utilized. And no pollutant is discharged. An independent seawater ascending channel is created, and the seawater ascending channel is arranged in a condenser, so that steam loss generated by seawater in the seawater ascending channel is avoided. And the plurality of condensers and the plurality of photovoltaic assemblies which are arranged on the same horizontal plane and are arranged on the same mounting rack are combined to form a module. The size and number of the modules can be adjusted to meet the requirements of various scales. And a new way is provided for solving the problem of power and water supply in islands and arid regions.

Description

[0001] Technical field [0002] The invention relates to a solar power generation and seawater separation technology, in particular to a solar seawater electricity, water-salt co-production technology and equipment. Background technique [0003] In 1872, the world's first large-scale solar-powered seawater desalination device was built in Chile, which is a symbol of the disc solar-powered seawater desalination technology. The solar interfacial evaporation technology, which has set off a research boom in recent years, is only an improvement of the disk solar desalination technology. It is characterized in that the heating surface is lifted from the bottom of the pan to the sea surface. The top-mounted heating surface solar evaporation technology is a disruptive technology. Chinese researchers published the paper "Passive Solar Desalination Technology Route Analysis" published in the American Journal of Energy and Power Engineering, analyzing the development process of passive...
