Embodiment Construction

[0019] Solar floating seawater desalination device, including transparent roof 1, evaporation area 2, container 3, steam channel 4, hose 5, water-absorbing material 6, lower floating foam board 7, upper floating foam board 8, and the lower communicating container of transparent roof 1 3. The container 3 is an annular groove (both the transparent ceiling 1 and the container 3 are rotating bodies). The annular groove of the container 3 contains condensed water. The area surrounded by the cylinder in the container 3 is the evaporation area 2. The container 3 is connected with the evaporation area 2 through the steam channel 4, and the hose 5 is connected under the container 3. The upper surface of the evaporation area 2 is low-density seawater, which means that the fibers are wetted by absorbing part of the water from the seawater by using the fiber capillary phenomenon .

[0020] The working principle of the present invention: seawater becomes low-density seawater through the wa...

Abstract

A solar floating type seawater desalination device relates to a seawater desalination device. According to the technical scheme, the lower portion of a transparent ceiling is communicated with a container, the container is an annular groove, condensate water is contained in the annular groove of the container, the area defined by a cylinder in the container is an evaporation area, and steam in the evaporation area can reach the container; and low-density seawater is arranged on the upper surface of the evaporation area, and the low-density seawater is the seawater obtained by absorbing part of water from seawater by utilizing the capillarity of a water absorbing material so as to wet the water absorbing material on the upper surface of the evaporation area. The solar floating type seawater desalination device has the beneficial effects that the problem of low condensation efficiency caused by arranging the condensation surface on the transparent ceiling which is directly irradiated by sunlight is solved; the temperature of the seawater in the evaporation area is increased, so that the evaporation efficiency is improved, and solar energy resources are utilized to the maximum extent; and the salinity of the surface of the evaporation area is increased due to evaporation, and after the salinity is increased, the water absorbing material diffuses downwards to seawater, so that a stable concentration gradient is maintained.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a floating solar seawater desalination device. Background technique [0002] Water is the source of human life. There are abundant water resources on the earth, but most of them are undrinkable sea water, polluted lake water, river water, shallow groundwater and deep groundwater that are difficult to mine, etc., which exist in rivers, lakes and directly usable by humans. Underground fresh water is less than 0.36% of the total. All in all, the shortage of drinking water resources has become a global problem. [0003] In order to solve the above problems, people try to obtain drinking water through different ways, and seawater desalination is one of the key research topics. The focus of seawater desalination is to obtain the heat energy required for seawater distillation. Among various energy sources, solar energy has become the heat energy source for some emerging seawater desal...
