Embodiment 1
[0035] like Figure 1-3 As shown, a brackish water evaporation and desalination device includes a heat exchanger 1, a pool assembly and a heating assembly:
[0036] The pool assembly has a pool 2, an evaporation carrier 3 and a transparent glass cover 4. The pool 2 has an inner cavity 201 for accommodating brackish water. The opening of the inner cavity 201 faces upward, and the glass cover 4 The cover is provided at the opening of the inner cavity 201, the evaporation carrier 3 is rotatably installed in the inner cavity 201, the lower end of the evaporation carrier 3 is immersed in the brackish water in the inner cavity 201, and the upper end of the evaporation carrier 3 is located in the inner cavity 201. Above the surface, the evaporation carrier 3 has several capillary pores, and the capillary pores are used to make the brackish water in the inner cavity 201 flow upward;
[0037] The heating assembly has a first metal tube 5, a solar heating plate 6, a fixed magnet 7 and ...

Abstract
The invention relates to the technical field of brackish water treatment, in particular to a brackish water evaporation and desalination device, comprising a heat exchanger, a pool component and a heating component: the cold source outlet of the heat exchanger is communicated with the inlet of the first metal The outlet of a metal tube communicates with the bottom of the inner cavity, and there is a gap between the evaporation carrier and the glass cover in the inner cavity to form an evaporation area. The first metal tube is placed above the solar heating plate to condense sunlight. It is heated to the first metal tube, and the moving magnet is arranged on the turntable, and the impeller is driven by the outside natural wind to rotate, so the first metal tube cuts the relative movement of the magnetic line of force between the moving magnet and the fixed magnet, so that the first Electric current is generated on the metal tube to heat it, so as to realize the combination of wind energy and solar energy. After heating, the brackish water that reaches the inner cavity flows to the upper end of the evaporation carrier under the capillary action of the capillary pores to realize the evaporation and desalination of brackish water. , greatly improve the evaporation efficiency.
Description
technical field [0001] The invention relates to the technical field of brackish water treatment, in particular to a brackish water evaporation and desalination device. Background technique [0002] "Brackish water" is a common name, and its salt content is 1 to 10 grams per liter. my country's per capita water resources are about 30% of the world's average level, and water resources are scarce and unevenly distributed. Due to factors such as geomorphology, hydrogeology, climate and environment, and the influence of the "three wastes" pollution, the northwest region is arid and less rainy, and the surface water is mostly brackish water of varying degrees. According to statistics, the annual exploitable volume of brackish water in the northwest region is 4.69 billion cubic meters, mainly distributed in Gansu, Xinjiang, Ningxia and western Inner Mongolia. At present, most of the brackish water desalination devices are water treatment devices produced by using the principle of...
