[0031] The inverted evaporation device for collecting water using solar energy provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
[0032] See also Figure 1 The utility model provides an inverted evaporation device for collecting water using solar energy. The inverted evaporation device includes a water tank 3, an evaporator 1, a water absorbing member 2 and a water collecting container 6. The water tank 3 is filled with raw water to be evaporated. The water collecting container 6 is arranged in the water tank 3. The top of the water collecting container 6 is provided with an opening. The water absorbing member 2 is arranged on the water collecting container 6 and covers the opening. The water absorbing member 2 can absorb and drain water in the water tank 3 to the top. The evaporator 1 is arranged on the top of the water absorbing member 2 to heat the raw water to generate water vapor. The opening of the water collecting container 6 is used to condense the water vapor inside the water collecting container 6 to form condensed water.
[0033] Specifically, the raw water to be evaporated can be seawater or sewage, and water vapor is evaporated from the seawater or sewage to extract clean water. A water level detector can be installed in the water tank 3 to detect the water level in the water tank 3, and an alarm and a controller are installed on the outside of the water tank 3. The water level information detected by the water level detector is transmitted to the controller. The controller determines whether water needs to be added according to whether the water level is lower than the set value. If water needs to be added, the alarm can be activated to give a reminder.
[0034] In one embodiment, see Figure 1 Part of the water collecting container 6 is immersed in the raw water in the water tank 3. The raw water has a cooling effect on the water collecting container 6, that is, the low temperature of the raw water is used to cool the water vapor in the water collecting container 6 to condense and form condensed water, thereby realizing the automatic condensation function of water vapor. It has the advantages of simple structure, low cost and good condensation effect.
[0035] In one embodiment, see Figure 1 A limiting member is fixed in the water container to limit the water collection container from tipping over.
[0036] In the above embodiment, the water collecting container can float in the water tank by utilizing the buoyancy of the raw water. In order to prevent the water collecting container from tipping over, a limiter can be provided to limit the water collecting container from tipping over. For example, the limiter is a fixed ring 7. The water collecting container is inserted into the fixed ring. The fixed ring is fixedly connected to the water tank. There is a gap between the water collecting container and the fixed ring, so that only the water collecting container can move up and down without tipping over, thereby ensuring smooth water collection.
[0037] In one embodiment, see Figure 1 The inverted evaporation device also includes a water container 4 and a water outlet pipe 5. The water container 4 is arranged on the outside of the water tank 3. The water container 4 is connected to the water collecting container 6 through the water outlet pipe 5 so that the condensed water generated in the water collecting container 6 enters the water container 4 through the water outlet pipe 5 for collection.
[0038] In one embodiment, the water container 4 is disposed below the water tank 3 , and one end of the water outlet pipe 5 away from the water collecting container 6 extends from the bottom end of the water tank 3 to the outside to communicate with the water container 4 .
[0039] In the above embodiment, the water container 4 is arranged below the water tank 3, which helps the condensed water in the water collection container 6 to automatically flow into the water container 4 by gravity, so as to achieve the purpose of automatic collection. The water outlet pipe 5 can be installed at the bottom of the water collection container 6 to communicate with the inside thereof, or can be installed at the bottom end of the side wall to communicate with the inside thereof, which helps to ensure that the condensed water in the water collection container 6 is discharged from the water outlet pipe 5 to the water container 4 as much as possible.
[0040] It should be noted that the number of the water outlet pipe 5 is at least one, that is, the water collection container 6 can be connected to the water container 4 through multiple water outlet pipes 5. Of course, there can also be multiple water containers 4, each water outlet pipe 5 is connected to a water container 4. The number of water outlet pipes 5 and water containers 4 is not specifically limited in this application and can be flexibly set according to actual usage.
[0041] In one embodiment, the water absorbent 2 is in a barrel shape and is wrapped around the water collecting container 6 in an inverted manner, and part of the water absorbent 2 is immersed in the raw water, so as to ensure that the water absorbent 2 can continuously absorb the raw water to the top of the water absorbent 2 for heating the evaporator 1.
[0042] Specifically, the material of the water absorbent member 2 is water absorbent fiber cotton, and the thickness of the water absorbent member 2 is 1-5 mm. For example, the thickness of the water absorbent member 2 is 2 mm, 3 mm, or 4 mm, which can be flexibly selected according to actual use. The distance between the bottom end of the side wall of the water absorbent member 2 and the bottom end of the side wall of the water collection container 6 is 0-5 mm, which is conducive to ensuring that the water absorbent member 2 can absorb raw water.
[0043] In one embodiment, the top end face and the bottom end face of the evaporator 1 are both planes, and the bottom end of the evaporator 1 fits with the top end of the water absorbing member 2 to ensure that the evaporator 1 is in contact with the water absorbing member 2, which is beneficial to the evaporation of water vapor.
[0044] Specifically, the thickness of the evaporator 1 is 1-5 mm. Exemplarily, the thickness of the evaporator 1 is 2 mm, 3 mm, or 4 mm, which can be flexibly selected according to actual use.
[0045] In one embodiment, the material of the evaporator 1 includes at least one of hydrogel, hydrophilic polyurethane foam, carbon material, and hydrophobic polymer foam.
[0046] Since the evaporator 1 uses the water absorbing member 2 to absorb the raw water to the top for heating to generate water vapor, the evaporator 1 itself does not need a specific water absorbing function. Therefore, the material of the evaporator 1 can be a hydrophilic material, such as hydrophilic polyurethane foam, or a hydrophobic material, such as hydrophobic polymer foam, which has a wider range of applications.
[0047] In one embodiment, the edge of the evaporator 1 extends to the outside of the opening of the water collecting container 6. In this way, the raw water on the water absorbing member 2 corresponding to the opening can be heated, and the generated water vapor can enter the water collecting container 6 from the opening, which is conducive to increasing the production of water vapor, that is, helping to increase the water production.
[0048] In one embodiment, the water absorbing member 2 is fastened to the outer wall of the water collecting container 6 by a fastening belt.
[0049] In one embodiment, the water outlet pipe 5 is arranged in a spiral manner in the water tank 3 and immersed in the raw water, and the temperature difference is used to further condense the water vapor, thereby improving the condensation effect. In addition, the water outlet pipe 5 is arranged in a spiral manner, which prolongs the time that the water outlet pipe 5 flows in the raw water, which also helps to improve the condensation effect.
[0050] In the above various embodiments, the evaporator is arranged on the upper part of the water absorbing member. The evaporator uses solar energy to heat the water sucked by the water absorbing member to generate water vapor. The water vapor enters the water collecting container through the opening of the water collecting container. Since the water collecting container is partially immersed in the raw water (sewage or seawater, etc.) in the water tank, the raw water condenses the water vapor in the water collecting container. Therefore, the water vapor can condense in the water collecting container to form condensed water and be discharged from the water outlet pipe, thereby achieving the purpose of concentrating and collecting water vapor using solar energy. Since the water vapor condenses in the water collecting container and does not adhere to the evaporator, the light absorption of the evaporator will not be weakened, thereby ensuring the evaporation rate, which is beneficial to improving the water collection efficiency; and the top end face of the evaporator is isolated from the water absorbing member, which has an anti-fouling effect, and also helps to ensure that the light absorption is not affected; at the same time, the designed inverted evaporation device has a simple overall structure, can be used repeatedly, and has low cost.
[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the utility model.
