Description

Technical Field

[0001] The present invention relates to the technical field of seawater evaporation and desalination, and in particular to a seawater evaporation and condensation device. Background Art

[0002] With the continuous development and progress of society, the demand for fresh water resources in all walks of life is increasing. Seawater desalination is a technology that uses seawater desalination to produce fresh water. Seawater is desalinated and collected for use in production and life. Most of the common seawater desalination collection equipment is relatively large and has a complex structure. It requires a lot of electricity or other energy to support. When the equipment fails and needs maintenance, it takes a lot of time and money, thus increasing the cost of seawater desalination.

[0003] In the related technology, reference can be made to the Chinese invention patent with authorization application number CN202110039177.2, which discloses an offshore fresh water collection device, including a fresh water condensation collection plate, a floating chassis, a wave-proof wall, a fresh water collection port, a fresh water collection barrel, a fresh water collection pipe and a fresh water storage tank. On sunny days, the seawater in the device is evaporated by utilizing the greenhouse effect of direct sunlight or concentrated sunlight, and is condensed and collected through the fresh water condensation collection plate to obtain fresh water. On rainy days, rainwater is directly collected using a funnel-shaped fresh water condensation collection plate to obtain fresh water.

[0004] When sunlight shines directly on the fresh water condensation collection plate and the wave-breaking wall, the seawater in the inner cavity of the wave-breaking wall evaporates and rises due to the heat. The water vapor rises and contacts the fresh water condensation collection plate and condenses. It slides downward into the fresh water collection barrel as the wall of the condensation collection plate tilts. However, when sunlight shines on the fresh water condensation collection plate, the temperature of the fresh water condensation collection plate will also rise, thereby reducing the condensation effect of the water vapor. In addition, there is a probability that the condensed fresh water will directly fall into the chamber between the wave-breaking wall and the fresh water collection barrel. Although the cost of seawater desalination collection is reduced, the efficiency of seawater desalination collection is also reduced. Summary of the invention

[0005] In order to save the cost of seawater desalination collection and improve the efficiency of seawater desalination collection, the present invention application provides a seawater evaporation and condensation device.

[0006] The present application provides a seawater evaporation and condensation device, which adopts the following technical solution:

[0007] A seawater evaporation and condensation device comprises a shell, wherein an evaporation cylinder is arranged in the shell, an evaporation chamber is arranged in the evaporation cylinder, a water supply port for seawater to enter is arranged at the bottom of the evaporation chamber, a condensation chamber is formed between the evaporation cylinder and the shell, the evaporation chamber is communicated with the top of the condensation chamber, a condensation structure is arranged at the condensation chamber, and a collecting member for collecting fresh water is arranged in the shell.

[0008] By adopting the above technical scheme, seawater enters the evaporation chamber through the water supply port, and sunlight shines on the shell, causing the seawater in the evaporation chamber to evaporate. After the seawater evaporates, it escapes from the top of the evaporation chamber to the condensation chamber. The condensation structure reduces the temperature of the inner wall of the condensation chamber. The evaporated seawater cools down and condenses to form fresh water after contacting the inner wall of the condensation chamber. The fresh water is collected in the condensation chamber and collected by the collecting member, thereby realizing the desalination and collection of seawater. By utilizing sunlight to evaporate the seawater, and cooperating with the condensation structure to condense the evaporated seawater, there is no need to set up an additional driving source, thereby reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0009] Optionally, the condensation structure includes a plurality of capillary channels vertically arranged on the shell, and the plurality of capillary channels are sequentially arranged along the circumference of the shell.

[0010] By adopting the above technical solution, the shell is placed in a seawater environment, and the seawater enters the evaporation chamber through the water supply port. The seawater in the capillary channel is transported from the bottom of the capillary channel to the top of the capillary channel under the capillary action. Sunlight irradiates the shell, and the shell is provided with capillary channels around the shell. The seawater in the top of the capillary channel vaporizes and evaporates. The vaporization heat required for vaporization is supplied by the sensible heat released by the temperature drop of the water body itself and the sunlight irradiation, causing the water body to cool down. After the water temperature drops, a temperature difference occurs between the water and the air. The air generates sensible heat due to this temperature difference and transfers it to the evaporation chamber. The water body, but the water temperature continues to drop to release sensible heat to make up for the insufficient heat of vaporized water. Therefore, the water temperature continues to drop, thereby generating heat convection with the inner wall surface to reduce the temperature of the inner wall surface. No additional energy supply equipment is required. The evaporated seawater can be condensed only by the cooperation of sunlight and capillary channels. The seawater in the evaporation chamber evaporates and rises and dissipates into the condensation chamber. It is cooled and condensed after contacting the inner wall of the shell, and the condensed fresh water is collected by the collecting component. Therefore, the cost of seawater desalination collection is reduced and the efficiency of seawater desalination collection is improved.

Since the capillary channel is arranged on the outer surface of the lower shell, the temperature of the inner surface of the lower shell is lower than that of the inner surface of the upper shell. After the seawater evaporates, the steam preferentially chooses the inner wall surface for condensation, thereby effectively reducing the probability that the seawater evaporation chamber cannot work continuously and reliably due to the condensation of steam on the top of the shell blocking the sunlight, thereby improving the efficiency of seawater desalination collection.

[0014] By adopting the above technical solution, the seawater below the evaporation chamber enters the evaporation chamber through the water supply port, the seawater between the outer shell and the lower shell enters the condensation space through the water inlet channel, and the seawater outside the outer shell is transported to the top of the capillary channel through the bottom of the capillary channel. The sunlight shines on the connection shell and the outer shell, and the seawater in the top of the capillary channel vaporizes and evaporates. The vaporization heat required for vaporization is supplied by the sensible heat released by the temperature drop of the water body itself and the sunlight, causing the water body to cool down. After the water temperature drops, a temperature difference occurs between the water and the air. The air generates sensible heat due to this temperature difference and transfers it to the water body, but the water The body temperature continues to drop and releases sensible heat to make up for the insufficient heat of vaporized water. Therefore, the water temperature continues to drop, thereby generating heat convection with the inner wall of the outer shell, which reduces the temperature of the inner wall of the outer shell. The seawater in the condensation space is heated and vaporized, and then encounters the inner wall of the outer shell for cooling and condensation. At the same time, the seawater evaporated from the capillary channel on the outer surface of the lower shell is also cooled and condensed after encountering the inner wall of the outer shell. The condensed fresh water is collected by the liquid collecting component, thereby realizing multi-stage recycling of seawater, reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0015] Optionally, the upper shell and the connecting shell are both made of light-transmitting material.

[0016] By adopting the above technical solution, the light-transmitting material reduces the absorption of sunlight, thereby improving the efficiency of seawater evaporation caused by sunlight, thereby improving the efficiency of seawater desalination collection.

[0018] By adopting the above technical solution, the seawater in the evaporation chamber evaporates and escapes into the condensation chamber, the steam contacts the inner wall of the lower shell and cools down and condenses into fresh water, the fresh water slides along the inner wall of the lower shell to the liquid collecting plate and gathers on the liquid collecting plate, the fresh water enters the liquid collecting chamber through the liquid guide hole for collection, thereby realizing the collection of fresh water, all the condensed fresh water in the condensation chamber can drip onto the liquid collecting plate, thereby improving the efficiency of seawater desalination collection.

[0019] Optionally, the liquid collecting plate includes a liquid collecting portion, a vertical portion and a liquid conducting portion which are integrally arranged together, the liquid collecting portion is fixed on the inner wall of the lower shell body and extends horizontally inward, the vertical portion is located at one end of the liquid collecting portion away from the inner wall of the lower shell body and extends upward, a liquid conducting groove is formed between the liquid collecting portion and the vertical portion and the lower shell body, the liquid conducting hole is provided on the liquid collecting portion and connects the liquid conducting groove and the liquid collecting cavity, the liquid conducting portion is located at one end of the vertical portion away from the liquid collecting portion, and the evaporating tube is provided on the liquid conducting portion.

[0020] By adopting the above technical solution, the seawater in the evaporation chamber evaporates and escapes into the condensation chamber, part of the steam condenses after contacting the inner wall of the upper shell and drips directly onto the liquid guide portion from the inner top wall of the upper shell, and flows through the vertical portion through the liquid guide portion and is collected in the liquid guide groove, the remaining steam condenses after contacting the inner wall of the lower shell and slides along the inner wall of the lower shell to be collected in the liquid guide groove, the fresh water in the liquid guide groove enters the liquid collecting chamber through the liquid guide hole for collection, thereby realizing the collection of desalinated seawater, and the fresh water is collected in the liquid guide groove to reduce the probability of fresh water accumulating on the liquid guide portion to cool the evaporator, thereby improving the efficiency of seawater evaporation by heat, thereby improving the efficiency of seawater desalination collection.

[0021] Optionally, there are a plurality of liquid conducting holes, and the plurality of liquid conducting holes are arranged at intervals on the liquid collecting portion.

[0025] Optionally, a water supply pipe is provided at the bottom end of the lower shell, and the water supply pipe passes through the liquid collecting chamber and the water supply port and is connected to the evaporation chamber.

[0026] By adopting the above technical solution, the shell is placed in a seawater environment, and seawater enters the evaporation chamber through a water supply pipe, so that the liquid level of the seawater in the evaporation chamber is consistent with the liquid level of the external seawater environment. When the seawater evaporates, seawater continues to enter from the water supply pipe to realize the supply of seawater. There is no need to set up additional water supply equipment, thereby reducing the cost of seawater desalination collection.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Seawater enters the evaporation chamber through the water supply port, and sunlight shines on the shell, causing the seawater in the evaporation chamber to evaporate. After the seawater evaporates, it escapes from the top of the evaporation chamber to the condensation chamber. The condensation structure reduces the temperature of the inner wall of the condensation chamber. The evaporated seawater cools down and condenses to form fresh water after contacting the inner wall of the condensation chamber. The fresh water is collected in the condensation chamber and collected by a collecting member, thereby realizing the desalination and collection of seawater. By utilizing sunlight to evaporate the seawater, and cooperating with the condensation structure to condense the evaporated seawater, there is no need to set up an additional driving source, thereby reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0029] 2. The shell is placed in a seawater environment. The sunlight makes the temperature of the top glass of the shell higher than the inner wall of the condensation chamber. The steam preferentially condenses on the inner wall of the condensation chamber, thereby effectively reducing the top glass from blocking light due to steam condensation, thereby reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0030] 3. The seawater between the outer shell and the lower shell enters the condensation space through the water inlet channel, and the seawater outside the outer shell is transported to the top of the capillary channel through the bottom of the capillary channel. Sunlight shines on the connection shell and the outer shell, the seawater evaporates, and the water temperature continues to drop, thereby generating heat convection with the inner wall of the outer shell, so that the temperature of the inner wall of the outer shell is reduced. After the seawater in the condensation space is heated and vaporized, it encounters the inner wall of the outer shell for cooling and condensation. At the same time, the seawater evaporated from the capillary channel on the outer surface of the lower shell is also cooled and condensed after encountering the inner wall of the outer shell. The condensed fresh water is collected by the liquid collecting component, thereby realizing multi-stage recycling of seawater. The multi-stage wall setting can effectively utilize the phase change of seawater, and the water vapor escaped from the low-level outer wall is recovered through the high-level inner wall, and collected layer by layer to expand the output of fresh water, thereby reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0031] 4. The capillary channel setting on the outer wall of the shell can reduce the need for a water transport pump. By utilizing capillary force, water can be easily sucked to a higher place, and water can be continuously transported to maintain the height of the water body in the channel. The refrigeration effect of the wet-bulb temperature of water can greatly reduce the cost of recovering steam. The setting of the four walls can effectively utilize direct sunlight at different angles, so that the water body in the channel can be continuously and efficiently cooled, avoiding unstable evaporation of the water body in the channel due to different light angles.

[0032] 5. After evaporation, the seawater in the evaporation chamber escapes into the condensation chamber. After the steam contacts the inner wall of the lower shell, it cools down and condenses into fresh water. The fresh water slides along the inner wall of the lower shell to the liquid collecting plate and gathers on the liquid collecting plate. The fresh water enters the liquid collecting chamber through the liquid guide hole for collection, thereby realizing the collection of fresh water. All the condensed fresh water in the condensation chamber can drip onto the liquid collecting plate, thereby improving the efficiency of seawater desalination collection.

[0033] 6. The device is simple and portable, occupies a small area, has low requirements for the installation environment, and is low in cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Reference Figure 2 and Figure 3 A liquid collecting chamber 5 is formed between the liquid collecting portion 41, the vertical portion 42, the liquid guiding portion 43 and the inner bottom wall of the lower shell 11. The liquid collecting chamber 5 is located below the evaporation chamber 21 and the condensation chamber 3. A liquid guiding hole 44 is provided on the liquid collecting plate 4.

There are multiple liquid guiding holes 44, which are spaced apart on the liquid collecting portion 41 and are used to connect the liquid guiding groove 411 and the liquid collecting chamber 5.

[0047] Reference Figure 2 and Figure 3 A water supply pipe 14 is provided at the bottom end of the lower shell 11. The water supply pipe 14 passes through the liquid collecting chamber 5 and the water supply port 22 and is connected to the evaporation chamber 21 and is used to transport seawater.

[0048] Reference Figure 2 , Figure 3 and Figure 4 A liquid collecting part 7 for collecting fresh water is provided in the outer shell 6. The liquid collecting part 7 includes a water collecting plate 71 and a water guide plate 72. The water collecting plate 71 includes a horizontal portion 711 and a vertical portion 712 that are integrally formed. The horizontal portion 711 is fixed on the four inner bottom walls of the outer shell 6 and extends horizontally inward. The vertical portion 712 is located at one end of the horizontal portion 711 close to the lower shell 11 and extends vertically upward. A water collecting chamber 73 is formed between the inner wall of the outer shell 6, the horizontal portion 711 and the vertical portion 712.

[0049] Reference Figure 2 , Figure 3 and Figure 4The water guide plate 72 is fixed on the inner wall of the water collecting chamber 73, and the opposite side walls of the water guide plate 72 are respectively fixed to the inner wall of the outer shell 6 and the vertical portion 712. A water guide groove 74 is formed between the water guide plate 72, the vertical portion 712 and the inner wall of the outer shell 6. The water guide groove 74 is located above the water collecting chamber 73. The water guide plate 72 has a water guide hole 721 for guiding condensed water into the water collecting chamber 73. There are multiple water guide holes 721, which are spaced apart on the water guide plate 72 and are used to connect the water guide groove 74 and the water collecting chamber 73.

[0050] Reference Figure 2 and Figure 3 , the upper shell 12 is buckled on the lower shell 11, and the connecting shell 63 is buckled on the outer shell 6, and the lower shell 11 and the outer shell 6 are placed in a seawater environment. Part of the seawater enters the evaporation chamber 21 through the water supply pipe 14, and part of the seawater enters the condensation space 61 through the water inlet channel 62. The liquid level of the seawater entering the condensation space 61 is lower than the height of the vertical portion 712. The sunlight shines through the top of the upper shell 12 and the connecting shell 62 and irradiates the surface of the seawater in the evaporation chamber 21 and in the condensation space 61. The seawater is heated and evaporated, and the steam in the evaporation chamber 21 rises and escapes from the evaporation chamber 21 to the condensation chamber 3. Part of the steam contacts the inner top wall of the upper shell 12 and condenses to form fresh water and drips on the liquid guide portion 43; part of the steam in the condensation space 61 contacts the inner top wall of the connecting shell 63 and condenses to form fresh water and drips on the water guide plate 72. Part of the steam escapes and contacts the inner wall of the outer shell 6 and condenses to form fresh water and gathers on the water guide plate 72.

[0051] Reference Figure 2 and Figure 3 , the seawater on the outer surface of the lower shell 11 enters the capillary channel 311 and moves from the bottom of the capillary channel 311 to the top of the capillary channel 311 under the capillary action. The sun shines on the capillary channel 311, and the seawater in the top of the capillary channel 311 evaporates and vaporizes. The vaporization heat required for vaporization is supplied by the sensible heat released by the temperature drop of the water body itself and the sunlight, causing the water body to cool down. After the water temperature drops, a temperature difference occurs between the water body and the air. The air generates sensible heat due to this temperature difference and transfers it to the water body, but the water body temperature continues to drop and releases sensible heat to make up for the insufficient heat of vaporized water. Therefore, the water body temperature continues to drop, thereby generating heat convection with the inner wall surface of the lower shell 11, so that the temperature of the inner wall surface is reduced. At the same time, under the sunlight, the temperature of the top glass of the upper shell 12 is higher than the inner wall surface of the condensation chamber 3, and the steam preferentially selects the inner wall surface of the condensation chamber 3 for condensation, thereby effectively reducing the top glass from blocking light due to steam condensation. The steam condenses after contacting the inner wall surface of the lower shell 11. The evaporation principle on the outer shell 6 is the same and will not be repeated here.

[0052] Reference Figure 2 , Figure 3 and Figure 4The seawater in the capillary channel 311 on the outer surface of the lower shell 11 evaporates and then escapes into the condensation space 61 for condensation. The fresh water in the condensation chamber 3 drips into the liquid guide groove 411 and gathers. The fresh water on the liquid guide portion 43 slides into the liquid guide groove 411. The fresh water in the liquid guide groove 411 passes through the liquid guide hole 44 and then gathers in the liquid collecting chamber 5. The fresh water in the condensation space 61 passes through the water guide hole 721 and gathers in the water collecting chamber 73. Finally, the fresh water in the liquid collecting chamber 5 and the water collecting chamber 73 can be drawn out through an external water pipe (not shown in the figure).

[0053] Reference Figure 2 and Figure 3 There is no need to set up additional energy supply equipment. The evaporated seawater can be condensed only by the cooperation of sunlight and the capillary channel 311. The seawater in the evaporation chamber 21 evaporates and rises and escapes into the condensation chamber 3. After contacting the inner wall of the shell 1, it is cooled and condensed, and the condensed fresh water is collected by the liquid collecting chamber 5, thereby reducing the cost of seawater desalination collection and improving the efficiency of seawater desalination collection.

[0054] Reference Figure 2 and Figure 3 The capillary channel 311 on the outer wall of the lower shell 11 and the outer shell 6 can reduce the need for a water transport pump. By utilizing capillary force, water can be easily sucked to a higher place, and water can be continuously transported to maintain the height of the water body in the channel. The setting of the four walls can effectively utilize direct sunlight at different angles, so that the water body in the channel can be continuously and efficiently cooled, avoiding unstable evaporation of the water body in the channel due to different light angles.

[0055] Reference Figure 2 and Figure 3 At the same time, since the capillary channel 311 is arranged on the outer surfaces of the lower shell 11 and the outer shell 6, the inner surface temperature of the lower shell 11 is lower than the inner surface of the upper shell 12. After the seawater evaporates, the steam preferentially chooses the inner wall surface for condensation, thereby effectively reducing the probability that the top wall of the upper shell 12 blocks sunlight due to steam condensation, resulting in the seawater evaporation chamber being unable to work continuously and reliably, thereby improving the efficiency of seawater desalination collection.

[0056] In other embodiments, the seawater evaporation and condensation device may have a multi-layer shell, that is, a shell with a capillary channel may continue to be added around the outer shell 6. The relationship between the multi-layer shells is consistent with the relationship between the lower shell 11 and the outer shell 6 in the present embodiment, that is, as long as the temperature of the steam coming out of the outer wall of the inner layer is higher than the temperature of the inner wall of the outer layer, and there is a temperature difference between the two, the structure can continue to be added to meet actual needs.

[0057] The working principle of the embodiment of the present application is as follows:

[0058] Part of the seawater enters the evaporation chamber 21 through the water supply pipe 14, and part of the seawater enters the condensation space 61 through the water inlet channel 62. The liquid level of the seawater entering the condensation space 61 is lower than the height of the vertical portion 712. The sunlight shines through the upper shell 12 and the top of the connecting shell 63 onto the surface of the seawater in the evaporation chamber 21 and in the condensation space 61. The seawater evaporates due to the heat, and the steam in the evaporation chamber 21 rises and escapes from the evaporation chamber 21 to the condensation chamber 3. Part of the steam contacts the inner top wall of the upper shell 12 and condenses to form fresh water and drips onto the liquid guide portion 43; part of the steam in the condensation space 61 contacts the inner top wall of the connecting shell 63 and condenses to form fresh water and drips onto the water guide plate 72. Part of the steam escapes and contacts the inner wall of the outer shell 6 and condenses to form fresh water and gathers on the water guide plate 72.

[0059] The seawater on the outer surface of the lower shell 11 enters the capillary channel 311 and moves from the bottom of the capillary channel 311 to the top of the capillary channel 311 under the capillary action. The sun shines on the capillary channel 311, and the seawater in the top of the capillary channel 311 evaporates and vaporizes, which reduces the temperature of the inner wall surface. The steam condenses after contacting the inner wall surface of the lower shell 11. The seawater in the capillary channel 311 on the outer surface of the lower shell 11 evaporates and dissipates into the condensation space 61 for condensation. The fresh water in the condensation chamber 3 drips into the liquid guide groove 411 and is gathered. The fresh water on the liquid guide part 43 slides into the liquid guide groove 411. The fresh water in the liquid guide groove 411 passes through the liquid guide hole 44 and is gathered in the liquid collecting chamber 5. The fresh water in the condensation space 61 passes through the water guide hole 721 and is gathered in the water collecting chamber 73.

[0060] No additional energy supply equipment is required. The evaporated seawater can be condensed only through the cooperation of sunlight and the capillary channel 311. The multi-stage recycling of seawater is achieved through the two layers of capillary channels 311, which reduces the cost of seawater desalination collection and improves the efficiency of seawater desalination collection.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
