Problems solved by technology

Freezing and distillation have insurmountable disadvantages, wherein distillation consumes a large amount of energy and produces a large amount of scale in the instrument, but not much fresh water is obtained; and freezing also consumes a lot of energy, but The resulting fresh water tastes bad and is hard to drink
The vacuum freezing seawater desalination process includes degassing, precooling, evaporative crystallization, ice crystal washing, steam condensation and other steps. Seawater desalination aquatic products can meet the national drinking water standard, but the equipment investment, energy consumption and maintenance costs are relatively high

Embodiment 1

[0037] A solar double-effect seawater desalination device, comprising a device bracket, a solar polysilicon photovoltaic panel 6 is arranged on the top of the device bracket, and a deep seawater water distributor 1 connected to a deep seawater inlet 10 is arranged below the solar polysilicon photovoltaic panel 6, A medium air passage is set under the deep sea water distributor 1, one end of the medium air passage is connected to the medium air intake louver 9, and the other end is connected to the exhaust fan 11 with a rodent-proof net, and the medium air passage is provided with The solar heat collector and the deep sea water cooling pump 4, the sea water collecting tray 7 is installed under the solar heat collector, the deep sea water cooling pump 4 is connected to the deep sea water inlet 10 above, and the fresh water collecting water tray 13 is installed below , the fresh water collection tray 13 is connected with a fresh water outlet 12, and the deep seawater cooling pump ...

Embodiment 2

[0043] The working process of the solar double-effect seawater desalination device and the seawater desalination method thereof of the present embodiment is as follows:

[0044]The solar double-effect seawater desalination device and seawater desalination method thereof, when subjected to solar radiation, the solar polysilicon photovoltaic panel 6 generates electric energy, supplies power to the exhaust fan 11 to operate, and controls the suction of the deep seawater supply pump (external configuration) relay. At the same time, the working medium in the evaporative and heat-absorbing section 2-1 of the solar heat collector boils and absorbs heat. After the phase change of the working medium, the heat is transferred to the condensing and heat-releasing section 2-2 of the solar heat collector at the speed of sound, so that the heat and the medium air are classified. enthalpy-enhancing treatment. Under the operation of the external water pump, the deep seawater enters the solar d...

Abstract

The invention relates to the technical field of seawater desalination of renewable energy, in particular to a solar double-effect seawater desalination device and a seawater desalination method thereof. The structure of the device includes: solar heat collector, solar polysilicon photovoltaic panel, deep seawater heat preservation water storage tank, deep seawater cooling pump, deep seawater distributor, freshwater collection water tray, exhaust fan, device bracket and control box. This device evaporates seawater After the saturation enthalpy increase treatment, it meets the surface cooler with the corresponding low-temperature seawater as the medium, and the medium air changes its water vapor density, thereby producing fresh water precipitation. The present invention utilizes solar radiation photothermal energy, solar radiation photovoltaic energy and ocean energy. Except for the transportation work of the deep seawater supplied by the system, the device adopts renewable energy, and the heat transmission adopts boiling heat transfer, which has large temperature difference and high efficiency. , and because fresh water is precipitated through the water vapor density difference of the medium air, the quality of drinking water is better.

Description

technical field [0001] The invention relates to the technical field of seawater desalination of renewable energy, in particular to a solar double-effect seawater desalination device and a seawater desalination method thereof. Background technique [0002] For a long time, human beings have made various development efforts on fresh water, especially seawater desalination technology, which has made great progress in recent years. However, the ubiquity of efficiency, benefit and purity seriously restricts the development of seawater desalination. [0003] At present, seawater desalination for drinking water generally adopts distillation method or freezing method, that is, seawater is frozen to freeze, and the salt is separated out when the liquid seawater turns into solid ice. Freezing and distillation have insurmountable disadvantages, wherein distillation consumes a large amount of energy and produces a large amount of scale in the instrument, but not much fresh water is obt...
