Embodiment 1
[0035] Such as 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 containing brackish water, the opening of the inner cavity 201 faces upwards, and the glass cover 4 The cover is set 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 a number of capillary pores, which 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 several moving mag...

The invention relates to the technical field of brackish water treatment, in particular to a brackish water evaporation desalting device which comprises a heat exchanger, a pool assembly and a heating assembly. A cold source outlet of the heat exchanger is communicated with an inlet of a first metal pipe, and an outlet of the first metal pipe is communicated with the bottom of an inner cavity; a gap is reserved between an evaporation carrier and a glass cover in the inner cavity to form an evaporation interval, the first metal pipe is arranged above a solar heating plate, sunlight is concentrated to the first metal pipe to heat the first metal pipe, a movable magnet is arranged on a rotary disc, an impeller is driven by external natural wind to rotate, therefore, the first metal pipe does relative motion for cutting magnetic lines of force between the movable magnet and a fixed magnet, current is generated on the first metal pipe to heat the first metal pipe, so that wind energy and solar energy are combined, brackish water reaching the inner cavity after being heated flows to the upper end of the evaporation carrier under the capillary action of capillary holes, brackish water evaporation desalination is achieved, and the evaporation efficiency is greatly improved.
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 popular 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 in short supply and unevenly distributed. Due to factors such as landforms, hydrogeology, climate and environment, as well as the impact of "three wastes" pollution, the northwest region is dry and rainless, and the surface water is mostly brackish water of varying degrees, and the problem of water shortage is particularly prominent. According to statistics, the annual exploitable volume of brackish water in Northwest China 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...
