Problems solved by technology

But this device still has low efficiency and high energy deficiency.
[0008] Judging from the technologies disclosed in Chinese patents, there is still a common deficiency in the prior art, that is, when desalination of seawater is realized and fresh water is discharged from the system or device, part of the energy is also taken away, so that the energy cannot be fully Be exploited

Embodiment Construction

[0019] The device composition and working principle of the present invention are explained in detail below in conjunction with the accompanying drawings:

[0020] attached figure 1In the given embodiment of the present invention, the solar energy is collected by the solar heat collector 12 and heats the heat pipe arranged in the heat collector 12, and then the circulating water flowing through the heat collector 12 is heated to the boiling point, and the cycle of reaching the boiling point Water enters the steam tank 13 from the solar heat collector 12 through the inlet 21, so that steam is generated in the tank 13, and part of the supplementary circulating water and unevaporated circulating water returns to the heat collector 12 through 22, forming a self-circulation process. The water in the evaporation tank 13 is heated and converted into steam, which can be sent to the power generation steam turbine 11 and the evaporator 17 respectively through the tee 24 . The amount of ...

Abstract

The present invention discloses a device which uses solar energy as energy for desalinating the sea water and simultaneously can produce salt. According to the device of the invention, a solar heat collector provides heat source to the evaporator and simultaneously provides steam for driving a turbine to generate power. The sucked cold sea water is sent to the evaporator after heating in a heat exchanger. The secondary steam generated by the evaporator is sent to a steam compressor for executing compression heating and then circulates into the evaporator. The desalinated condenser water generated in the evaporator is sent to the heat exchanger for heating the cold sea water. The supersaturated brine generated by the evaporator is sent to a salt settling tank of crude salt collection tank through a saturated brine pot. The device of the invention is also installed with a steam boiler.

Description

technical field [0001] The invention relates to a device for seawater desalination, in particular to a device for desalinating seawater by using solar energy as energy and producing salt at the same time. The device of the present invention is provided with a solar heat collector, an evaporator, a heat exchanger, a salt sedimentation tank, and pipelines, valves and pumps connecting each part. Background technique [0002] With the continuous and rapid development of social economy and the improvement of people's living standards, the problems of water resource shortage and water pollution have become increasingly prominent. Finding new water sources and saving water have become an important issue in today's society. Desalination of seawater to obtain fresh water is an ancient subject, and at the same time it is a focus of research in today's era. [0003] Traditional seawater desalination uses multi-stage evaporator groups for distillation treatment, which consumes a lot of...
