Embodiment Construction

[0023] The implementation of the present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0024] In order to distinguish the seawater extracted from the sea level and the seawater extracted from the seabed, this patent refers to the seawater extracted from the sea level as "normal temperature seawater", and the seawater extracted from the seabed as "low temperature seawater".

[0025] The solar desalination device includes a PLC automatic control system 8 installed on the solar mounting bracket 202, two sets of filtration systems 1, two sets of wind and solar hybrid power generation systems 3, forty-eight sets of solar heating systems 2 and the negative pressure matched with the solar heating systems The evaporation and condensation system 4, the negative pressure evaporation and condensation system 4 is conne...

Abstract

The invention provides a solar energy seawater desalination device which comprises an automatic control system, two sets of filtering systems, a wind-solar complementary power generation system, a plurality of sets of solar energy heating systems and a negative pressure evaporation and condensation system matched with the solar energy heating systems, wherein the negative pressure evaporation andcondensation system is connected with a fresh water collection tank through a water pipe. The normal temperature seawater extracted from the sea level is heated by a solar heater and then condensed with low-temperature seawater pumped out from deep wells on the seabed, the condensation efficiency is high, the water yield is high and the efficiency is at least ten times than that of the conventional solar evaporators. Compared with the reverse osmosis technology, the investment cost is low and the condensed solar heated seawater passes through the heat energy recovery device to heat the seawater entering the solar energy so that the seawater inlet temperature and the solar energy heating efficiency are improved and the condensed seawater finally returns to the sea without polluting the environment.

Description

technical field [0001] The invention belongs to the technical field of renewable energy and seawater desalination, and in particular relates to a solar seawater desalination device. Background technique [0002] The shortage of fresh water resources has always been a problem faced by human beings. With the impact of climate warming, more and more places are suffering from drought all year round, and water for humans and crops is seriously scarce. Solar desalination technology is of great significance to solve the above problems. [0003] At present, reverse osmosis technology and solar evaporation technology are most used in seawater desalination technology. Although reverse osmosis technology has a large amount of seawater desalination, the investment cost is huge. The disadvantages of low temperature, low water production, and low utilization efficiency of solar thermal energy. Therefore, on the basis of the existing research on solar evaporation technology, it is of grea...
