Embodiment 1

[0032] like figure 1 As shown, a concentrated solar steam generation system, the steam generation system includes a solar collector group 1, a steam generation device 2, a circulation pump 3, and a heat transfer working medium 4.

[0033] The steam generating device 2 includes an evaporation chamber 20, a heat transfer working medium storage tank 21, and a first heat pipe 22. The evaporation chamber 20 is arranged on the top of the heat transfer working medium storage tank 21, and the first heat pipe 22 penetrates through the bottom of the evaporation chamber 20 so that the first The heat dissipation section of the heat pipe 22 is located in the evaporation chamber 20 , and the heat absorption section extends into the heat transfer working fluid storage tank 21 . The first heat pipe used in this embodiment is a special heat pipe. The heat transfer medium inside the heat pipe is made of a mixture of various inorganic materials. The formula of this heat transfer medium was inven...

Embodiment 2

[0040] like figure 2 and image 3 Shown, a kind of seawater desalination system comprises the concentrating solar energy steam generation system described in claims 1 to 6 and a multi-stage steam condensation fresh water collection system, the fresh water collection system includes several stages of steam condensation devices 5, fresh water tanks 6, concentrated Salt water pool 7, water pump 8, seawater delivery pipeline 9.

[0041] The steam condensing device 5 includes an upper seawater preheating chamber 50, a lower steam condensing chamber 51, and several second heat pipes 52. The heat dissipation section of the second heat pipe 52 is arranged in the seawater preheating chamber 50, and its heat absorbing section is arranged in the steam condensing chamber. In the cavity 51, the top of the seawater preheating cavity 50 is provided with an exhaust port 501, and its outer facade is provided with a seawater inlet 502 and a seawater outlet 503 which are staggered up and down;...

Abstract

The invention provides a concentrating solar steam generation system and a seawater desalination system. The process of replacing a traditional electric steam boiler or a gas steam boiler with the concentrating solar steam generation system is promoted, the development of a solar medium-high temperature seawater desalination technology is promoted, the problem of high energy consumption of existing electric boilers or gas boilers and seawater desalination devices is solved, the systems have great practical significance in the improvement of the lack of water resources in China, and the solar energy is maximally used. It should be pointed out that the seawater desalination system is not limited to seawater desalination, and also can be applied brackish water desalination and general wastewater treatments in practical applications. The concentrating solar steam generation system also be applied to a solar thermal power generation system as a main heat source for solar thermal power generation.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a technology of a concentrating solar steam generation system and a seawater desalination system. Background technique [0002] On the one hand, the level of human energy consumption continues to increase, on the other hand, conventional fossil energy is increasingly exhausted, and the pollutant emissions associated with conventional fossil energy are increasingly unable to meet people's demand for future energy. Solar energy, as an inexhaustible new clean energy, is getting more and more attention, and the development of solar energy is making progress day by day. [0003] Existing industrial high-temperature steam is mainly produced by coal-fired or gas-fired or electric boilers, or the cost is high, or it is not friendly to the environment. If solar energy is used to concentrate the production of industrial high-temperature steam, the application ran...
