Description

Technical Field

[0001] The utility model belongs to the technical field of saline-alkali water treatment and relates to a saline-alkali water separation device based on natural energy. Background Art

[0002] During the treatment of saline-alkali land, washing water is usually sprayed into the saline-alkali land, and the saline-alkali land is rinsed and soaked with washing water to reduce the salinity in the saline-alkali land. In order to avoid further pollution of the environment by the saline-alkali water generated during the treatment process, it is also necessary to separate the water from the salt and alkali in the saline-alkali water. In the prior art, the dosing method and the heating method are often used to separate the water from the salt and alkali. The dosing method requires the introduction of additional agents into the saline-alkali water, which introduces additional pollution sources; the heating method requires the consumption of energy to heat the saline-alkali water, so that the water in the saline-alkali water evaporates, and the cost is very high when a large amount of saline-alkali water is treated.

[0003] Therefore, in view of the above-mentioned defects existing in the existing salt-alkali separation treatment of saline-alkali water in the process of saline-alkali land management, the utility model discloses a saline-alkali water separation device based on natural energy. Utility Model Content

[0004] The utility model aims to provide a saline-alkali water separation device based on natural energy, which can utilize solar energy to quickly heat saline-alkali water, evaporate the water in the saline-alkali water, then condense and separate the water vapor, and realize the reuse of condensed water.

[0007] The saline water is introduced into the water storage tank, and a shed is set above the water storage tank to form a relatively closed space.

The water vapor formed by evaporation escapes to the top of the heat collection part through the pores on the heat collection part and contacts the condensation part. Since the temperature of the condensation part is lower than the temperature of the water vapor, the water vapor condenses and liquefies at the condensation part to form droplets. The droplets drip down to the top surface of the heat collection part and flow along the inclined top surface to the water collection part at the edge of the heat collection part for collection and reuse.

[0032] The wall of the water storage tank 1 is made of an anti-repellent soil and anti-alkali layer to prevent the leakage of saline-alkali water. A shed 2 is arranged above the water storage tank 1, and the shed 2 can be set as a transparent plastic shed or a transparent glass shed. An inclined heat collecting part 3 is arranged on the top of the inner side of the shed 2, which is located above the water storage tank 1, and a plurality of pores 4 are arranged in an array on the heat collecting part 3. The heat collecting part 3 is made of black heat collecting material, which can quickly absorb and collect heat energy from sunlight, so that the inside of the shed 2 quickly heats up, thereby ensuring that the water in the saline-alkali water evaporates quickly. After the water vapor escapes upward through the pores 4 on the heat collecting part 3 to the top of the heat collecting part 3, it contacts the condensation part 7, and condenses and liquefies on the condensation part 7 to form droplets. The liquid droplets drip downward onto the top surface of the heat collecting part 3 under the action of gravity, and flow along the inclined water guiding groove 5 on the top surface of the heat collecting part 3 to the water collecting part 6 at the edge of the heat collecting part 3. The condensed water is collected and reused by the water collecting part 6. The collected condensed water 6 can be used for desalination and cleaning operations of saline-alkali land.

[0033] Furthermore, the height of the shed body 2 is greater than or equal to 1.5 m, and the span of the shed body 2 is set accordingly according to the span of the water storage tank 1 .

[0034] Furthermore, the condensation portion 7 is a hydrophobic plastic film made of hydrophobic plastic. When water vapor condenses into droplets on the hydrophobic plastic film, the droplets can drip quickly, thereby improving the collection efficiency of condensed water.

[0035] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0036] Embodiment 2:

[0037] A saline-alkali water separation device based on natural energy is improved on the basis of Example 1, such as Figure 2 As shown, the heat collecting part 3 includes a mounting frame and a heat absorbing cloth 31. The mounting frame is tiltedly arranged inside the shed body 2. The elevation end of the mounting frame is hinged to the shed body 2.

An inclination adjustment device 8 is arranged between the low-level end of the mounting frame and the top of the shed body 2. A lifting device 9 is arranged between the elevation end of the mounting frame and the top of the shed body.

[0038] A top beam is provided at the center line of the top of the inner side of the shed 2, and hinged ears are provided at both ends of the bottom of the top beam. A hinge shaft is provided at both ends of the elevation end of the mounting frame, and the hinge shaft is correspondingly hinged to the hinge hole on the hinged ear, so that the mounting frame can rotate around the elevation end to adjust the inclination angle of the heat absorbing cloth 31 on the mounting frame. A water collecting part 6 with an opening at the top is installed at the low-range end of the mounting frame, and the low-range end of the heat absorbing cloth 31 corresponds to the opening at the top of the water collecting part 6, and the condensed water sliding down along the top surface of the heat absorbing cloth 31 drips into the water collecting part 6 for collection.

[0039] The tilt adjustment device 8 is connected to the low-range end of the mounting frame and can drive the low-range end of the mounting frame to rotate around the high-range end of the mounting frame, thereby adjusting the tilt angle of the mounting frame. The lifting end of the lifting device 9 is connected to the hinge shaft of the high-range end of the mounting frame. The height of the heat absorbing cloth 31 on the mounting frame from the water tank 1 can be adjusted by lifting the lifting device 9 in the vertical direction.

[0040] Further, such as Figure 2 As shown, the high-level end of the mounting frame is rotatably provided with a cloth reel 32, and one end of the heat-absorbing cloth 31 is wound around the outside of the cloth reel 32. When salt-alkali separation is not required, the heat-absorbing cloth 31 is wound around the outside of the cloth reel 32 for storage to prevent the heat-absorbing cloth 31 from occupying too much space. When salt-alkali separation is required, the heat-absorbing cloth 31 is pulled out of the cloth reel 32, and the low-level end of the heat-absorbing cloth 31 is pulled to the opening position at the top of the water collection part 6 and fixed.
