[0002] This disclosure is based on and claims priority to Chinese application No. 202411969927.6, filed on December 30, 2025, the contents of which are incorporated herein by reference in their entirety. Technical Field

[0003] This disclosure relates to the field of evaporation technology, and in particular to an evaporation apparatus, an evaporation method, and a salt separation system. Background Technology

[0004] Globally, water scarcity and resource and energy shortages are intensifying, making the rational utilization and protection of water resources a focal point. Large quantities of highly concentrated brine generated during industrial production, if left untreated or improperly treated, will cause serious environmental pollution and waste valuable resources. Traditional brine treatment methods suffer from low efficiency, high cost, and low resource recovery rates, failing to meet the requirements of sustainable development. Therefore, developing efficient, economical, and environmentally friendly brine treatment technologies is of great significance for achieving the sustainable use of water resources and the resource recovery of industrial wastewater.

[0005] Currently, high-salinity water is often treated using evaporation technology, including natural evaporation, multi-effect evaporation, and mechanical vapor recompression evaporation. Natural evaporation is heavily limited by climatic conditions, requires a large evaporation area and a long processing time, resulting in low evaporation efficiency and a risk of leakage. Although multi-effect evaporation and mechanical vapor recompression evaporation have improved evaporation efficiency to some extent, these methods still face problems such as complex equipment structures, high energy consumption, and high operating costs.

Detailed Implementation

[0058] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure, that is, this disclosure is not limited to the described embodiments.

[0059] In the description of embodiments of this disclosure, the term "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two).

[0060] This disclosure uses terms such as "upper," "lower," "top," "bottom," "front," "back," "inner," and "outer" to indicate orientation or positional relationships. This is only for the convenience of describing this disclosure and is not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this disclosure.

[0061] Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. "Vertical" does not mean strictly vertical, but rather within the permissible range of error. "Parallel" does not mean strictly parallel, but rather within the permissible range of error. The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this disclosure.

[0062] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure depending on the specific circumstances.

[0063] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least some of the embodiments disclosed herein. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0064] As shown in Figures 1 to 6, in some embodiments, the evaporation apparatus of this disclosure includes:

[0065] The container 1 has a receiving space, and the container 1 has an air inlet 4 and an air outlet;

[0066] Fan 2 is configured to drive gas outside the container 1 into the container space and cause gas inside the container space to flow outward through the air outlet;

[0067] Evaporation component 3, disposed within a containment space, is configured to evaporate liquid by gas flowing through its surface or pores; and

[0068] A fluid supply component is configured to supply liquid to the evaporation component 3.

[0069] Specifically, the housing 1 can be a frame structure formed by beams or a box structure, and its shape can be cuboid, cylindrical, or prismatic. The housing space inside the housing 1 serves as the installation space for the evaporation component 3 and the airflow channel. Wheels 15 can be provided at the bottom of the housing 1 to facilitate the movement of the evaporation device. Optionally, the wheels 15 can be omitted, and the absence of wheels 15 is also within the scope of protection of this disclosure embodiment.

[0070] For example, the fan 2 can be located outside the housing 1. The fan 2 can be positioned at the air inlet 4 to allow external gas to enter the housing space by blowing air and exit through the air outlet; alternatively, the fan 2 can be located at the air outlet to allow external gas to enter the housing space by suction and exit through the air outlet. The fan 2 can be located on either side of the housing 1. If the housing 1 has a frame structure, the fan 2 can be fixed to the housing 1 by a bracket or similar means; if the housing 1 has a box structure, the fan 2 can be fixed to the side wall of the box or placed directly inside the box structure. Optionally, the fan 2 can also be located inside the housing 1.

[0071] For example, fan 2 can be an axial flow fan, which operates at high speed and can efficiently drive the flow of gas.

[0072] The fluid supply component can supply liquid to the evaporation component 3. One or more evaporation components 3 can be provided to absorb liquid. When the airflow passes through the evaporation component 3, the liquid can evaporate and be driven by the fan 2 to flow out of the container 1. Solid salt remains on the evaporation component 3 or falls off to the bottom on its own. The container 1 can have an air inlet 4 on one side or multiple air inlets 4 on multiple sides.

[0073] During evaporation, gas flows through multiple surfaces of the evaporation component 3. More preferably, all surfaces of the evaporation component 3 are unobstructed and can serve as evaporation surfaces. Furthermore, if the evaporation component 3 is made of a porous material, gas can also flow through the pores and carry away liquid. Thus, the evaporation component 3 forms a three-dimensional evaporation interface, increasing the number and surface area of ​​evaporation interfaces. A liquid film is formed on its entire evaporation surface, resulting in a higher evaporation efficiency than a two-dimensional evaporation interface, where, for example, in a container with liquid, only the upper surface forms an evaporation interface.

[0074] For example, this evaporation device can be used in various fields requiring liquid evaporation, such as pure water evaporation, zero wastewater discharge, and salt separation. Taking salt separation as an example, the liquid is a salt solution. During the evaporation process, solid salt remains on the evaporation component 3, which serves to hold the evaporated salt. Alternatively, the salt can detach and be collected below, thus achieving salt separation. This solution fully utilizes wind power to achieve ultra-fast evaporation for efficient liquid processing, enabling rapid evaporation and effective salt concentration. The salt remains on the evaporation component 3, preventing environmental pollution and eliminating the need for high-temperature heating. The high evaporation efficiency results in high salt separation efficiency.

[0075] This embodiment, by incorporating a fan 2, allows airflow from outside the container 1 to enter the container 1 through the air inlet 4 and circulate efficiently within it. As the air passes through the evaporator 3, it carries away moisture from the surface of the evaporator 3 material and discharges it outside the container 1 with the airflow. This solution fully utilizes the driving force of wind energy to achieve ultra-fast evaporation, efficiently processing liquids and achieving rapid evaporation without the need for high-temperature heating, resulting in high evaporation efficiency. Furthermore, this device has a small footprint. Since wind energy is an abundant and renewable energy source, it can save energy, improve resource recycling rates, provide technical support for the global new energy revolution and low-carbon development, has low cost, and is expected to significantly reduce industrial wastewater discharge, alleviating environmental pressure.

[0076] In some embodiments, an air outlet is provided on a first side 11 of the housing 1, and a fan 2 is provided outside the first side 11 and is configured to draw gas out of the housing space. At least one second side 12 of the housing 1 is provided with an air inlet 4, and the second side 12 is adjacent to or opposite to the first side 11.

[0077] In this embodiment, the second side 12 is adjacent to the first side 11, and the air inlet 4 and air outlet are located on adjacent sides of the housing 1. After the airflow enters the housing 1, it will change direction, which can extend the flow path of the gas in the housing 1 so as to flow more fully through the internal evaporation component 3 and optimize the evaporation effect. Alternatively, the second side 12 is opposite to the first side 11, and the air inlet 4 and air outlet are located on opposite sides of the housing 1. This can reduce the flow resistance of the airflow entering the housing 1 and reduce the power consumption of the fan 2. For example, for a large-volume evaporation device, the power requirement of the fan 2 can be reduced.

[0078] In some embodiments, as shown in Figures 1 and 2, a damper 13 is provided on the second side 12. The damper 13 can be opened and closed, and forms an air inlet 4 when open. Thus, the air inlet 4 can be flexibly opened or closed according to usage requirements. For example, when dampers 13 are provided on multiple second sides 12, a matching damper 13 can be selected to be in the open state according to the arrangement of the evaporation components 3, reducing the resistance to airflow within the housing 1 and increasing the coverage area of ​​the airflow on the evaporation components 3, thereby improving the effective evaporation area of ​​the evaporation components 3.

[0079] In some embodiments, the damper 13 is opened and closed by movement, and the damper 13 can be selectively held in different positions to adjust the size of the air inlet 4.

[0080] Specifically, the side of the damper 13 can be engaged in a groove, and the inner wall of the groove is provided with serrations. The damper 13 can be held in different positions as it moves within the groove. To facilitate adjustment of the position of the damper 13, a handle 14 can be provided at one end of the damper 13 along the first direction x. For example, if the fan 2 is located at the top of the receiving member 1, and the damper 13 moves along the height direction, the handle 14 is located at the top of the damper 13 to adjust its position along the height direction. Alternatively, the absence of a handle 14 is also within the scope of protection of this embodiment.

[0081] Optionally, the damper 13 can also be opened, closed, or the size of the air inlet 4 can be adjusted by rotating it.

[0082] This embodiment uses a movable damper 13 to open and close the air inlet 4 and adjust its size. It has a simple structure and is easy to operate. The size of the air inlet 4 can be adjusted linearly by the displacement of the damper 13, which can more accurately adjust the opening of the air inlet 4 to achieve the required evaporation performance.

[0083] In some embodiments, as shown in Figures 1 and 2, at least two dampers 13 are arranged side by side on the second side 12, and the direction of movement of the dampers 13 is perpendicular to the direction in which the at least two dampers 13 are arranged side by side. On the same second side 12, only some dampers 13 may be opened, or all dampers 13 may be opened.

[0084] Optionally, at least two dampers 13 are arranged side-by-side along the second direction y on the second side 12. The dampers 13 move along the first direction x to open or close, and the second direction y is perpendicular to the first direction x. The at least two dampers 13 arranged side-by-side on each second side 12 have the same size along the first direction x.

[0085] Optionally, at least two dampers 13 are arranged side-by-side along the first direction x on the second side 12, and the dampers 13 move along the second direction y to open or close. The at least two dampers 13 arranged side-by-side on each second side 12 have the same size along the second direction y.

[0086] This embodiment, by arranging at least two air dampers 13 side by side on the second side 12, allows for flexible selection of appropriate air inlet combinations during evaporation based on the arrangement of the evaporation component 3, thereby changing the airflow direction and forming a gas flow field within the containment 1 that matches the evaporation component 3, thus improving evaporation efficiency.

[0087] In some embodiments, the receiving member 1 is cuboid, and each of the four second sides 12 of the receiving member 1 is provided with an air inlet 4. At least two dampers 13 may be arranged side by side along the second direction y on each second side 12.

[0088] In this embodiment, air inlets 4 are provided on all four second sides 12 of the housing 1. This allows for flexible selection of the appropriate air inlet direction based on the arrangement of the evaporator 3, ensuring the evaporator 3 functions optimally. Furthermore, when all four air inlets 4 on the second sides 12 are open, airflow can enter evenly from all sides of the housing 1, ensuring full contact between any surface of the evaporator 3 and the airflow, and increasing the area of ​​the air inlet channel. This improves evaporation efficiency, thereby enhancing salt separation efficiency.

[0089] In some embodiments, the damper 13 has a louver structure, which includes multiple blades that can rotate synchronously or separately to form an air inlet 4 when rotated to the open state. Specifically, the multiple blades can be connected by a pull rope, a rotating rod, or other force transmission components to drive the force transmission components to achieve synchronous rotation of the multiple blades, thereby adjusting the angle of the blades to realize the opening and closing angle of the air inlet 4.

[0090] In this embodiment, the damper 13 is configured as a louver structure. For large evaporation devices, there is no need to move or rotate the damper 13 as a whole to open and close the air inlet 4. The blades rotate in place without occupying space around the evaporation device, saving space. Furthermore, when the damper 12 is large, it eliminates the need for overall movement, reducing control difficulty. In addition, airflow can enter through the spaces between adjacent blades, and the blades guide and distribute the airflow, making the air intake more uniform.

[0091] In some embodiments, the fan 2 has a speed regulator configured to adjust the rotational speed of the fan 2. The speed regulator may be located in the electrical control box. By adjusting the rotational speed of the fan 2, the gas flow rate can be changed, thereby improving evaporation efficiency while ensuring stable airflow within the containment 1, thus stabilizing the evaporation rate and optimizing evaporation performance.

[0092] In some embodiments, the evaporation component 3 is directly connected to the housing 1; and / or

[0093] The housing 1 is provided with a mounting beam, and the evaporator 3 is connected to the mounting beam; and / or

[0094] The housing 1 is provided with an installation beam and a partition 5. The partition 5 is set on the installation beam, and the evaporation component 3 is set on the partition 5.

[0095] Specifically, for the evaporator 3 directly connected to the receiving member 1, for example, hooks, fixing rings, or other connecting parts can be provided inside the receiving member 1 to install the evaporator 3 onto the connecting parts. For the receiving member 1 having a mounting beam, the mounting beam may include at least one of a crossbeam and a longitudinal beam, and the evaporator 3 can be directly connected to the mounting beam. For the receiving member 1 having a mounting beam and a partition 5, the partition 5 is placed or fixed on the mounting beam, for example, the partition 5 is placed horizontally on the mounting beam, or the partition 5 is inserted into a slot on the mounting beam, etc. The partition 5 is detachable or fixed relative to the mounting beam, and the evaporator 3 is placed or connected to the partition 5.

[0096] This embodiment connects the evaporation component directly to the housing 1, which simplifies the internal structure of the housing 1, reduces space occupation, and makes it easy to set the position of the evaporation component 3 according to actual needs.

[0097] Alternatively, the housing 1 may have a mounting beam inside, and the evaporator 3 may be connected to the mounting beam. This structure is more suitable for large evaporation devices. The mounting beam can strengthen the structure of the housing 1 and can divide the housing 1 into sections, reducing the difficulty of setting up the evaporator 3 or other structures, and facilitating a more flexible setting of the installation position of the evaporator 3.

[0098] Alternatively, the housing 1 may have an installation beam and a partition 5, with the partition 5 mounted on the installation beam and the evaporation component 3 mounted on the partition 5. This structure is better suited for large evaporation devices. The installation beam can strengthen the structure of the housing 1 and divide the housing 1 into sections, reducing the size of the partition 5. For example, multiple partitions 5 can be set in the same plane. Furthermore, the evaporation component 3 can be installed more flexibly by being mounted on the partition 5. If the partition 5 is detachable from the installation beam, it is easier to install and remove multiple evaporation components 3.

[0099] In some embodiments, as shown in FIG3, the evaporation device further includes a partition 5, which is installed in the housing 1. The partition 5 is used to connect the evaporation component 3 or change the gas flow direction in the housing 1. The partition 5 is provided with a vent, and / or the partition 5 has a gap around it for gas to flow through.

[0100] For the cuboid-shaped container 1, the partition 5 can be rectangular and can be installed horizontally or obliquely inside the container 1. For example, the partition 5 can be detachably installed inside the container 1. For example, the partition 5 can be formed by weaving metal mesh, with the ventilation part being the through holes formed by the metal mesh; or the partition 5 can have one or more through holes or through slots as ventilation parts, and their shape is not limited; or multiple partitions 5 can be arranged in the same plane, with gaps formed between adjacent partitions 5 or between the partition 5 and the container 1 for gas to flow through. This arrangement allows the partition 5 to be without ventilation parts, but of course, in order to reduce gas flow resistance, ventilation parts are still provided on the partition 5.

[0101] This embodiment, by setting the partition 5, allows for the convenient placement of the required number of evaporation components 3 at the desired locations. For example, the evaporation components 3 can be placed on the partition 5 or suspended below the partition 5. Moreover, after salt separation is complete, removing the partition 5 allows all evaporation components 3 to be removed from the housing 1 for salt separation, making the operation convenient. In addition, the mesh partition 5 facilitates the suspension and connection of the evaporation components 3 and the adjustment of their installation positions. Furthermore, the airflow entering from the air inlet 4 facilitates its passage through the mesh and out of the fan 2. Optionally, the evaporation device may also omit the partition 5, allowing the evaporation components 3 to be directly connected to the housing 1, or a liquid distribution pipe may be provided within the housing 1, with the evaporation components 3 fixed to the liquid distribution pipe.

[0102] In some embodiments, as shown in FIG4, multiple evaporation components 3 are provided, and the multiple evaporation components 3 are arranged at intervals, forming an airflow channel between adjacent evaporation components 3.

[0103] The shape of the evaporation component 3 is not limited. When the airflow enters the flow channel, it can come into contact with the surface of the evaporation component 3 around the flow channel to achieve liquid evaporation.

[0104] This embodiment, by setting multiple evaporation components 3 inside the housing 1, can maximize the evaporation area within a fixed volume of housing space, thereby improving the salt separation effect. Furthermore, it is necessary to ensure that the gas can flow smoothly in the flow channel after entering, and to ensure a certain gas flow rate to promote the evaporation process. Therefore, the number of evaporation components 3 must take into account both the factors of increasing the evaporation area and ensuring smooth gas flow.

[0105] In some embodiments, as shown in FIG4, the evaporation component 3 is sheet-like, and multiple evaporation components 3 are suspended at intervals in the space below the partition 5. For example, the partition 5 is mesh-like, and the top of the evaporation component 3 can be connected to the mesh partition 5 to allow the evaporation component 3 to unfold flat. For example, multiple evaporation components 3 can be arranged in parallel.

[0106] This embodiment suspends the sheet-like evaporator 3 below the partition 5, requiring only one partition 5, thus saving on the number of partitions 5 needed. The evaporator 3 has a large surface area, and both side surfaces are unobstructed, allowing it to absorb a significant amount of liquid before evaporation. The larger evaporation area also improves evaporation efficiency. Furthermore, as the damper 13 moves along the first direction x towards the fan 2 to open the air inlet 4, the space below the partition 5 is exposed first, allowing the airflow to directly reach the evaporator 3. After contacting the evaporator 3, the airflow flows upward under the suction of the fan 2, directly passing through the partition 5 with minimal resistance, reducing overall gas flow loss and saving energy. Additionally, the suspended evaporator 3 can obtain liquid through self-priming without requiring external power to supply liquid.

[0107] In some embodiments, as shown in FIG4, the air inlets 4 opposite to the sides of the plurality of evaporation components 3 are in an open state, that is, the air inlets 4 perpendicular to the second side 12 of the plate-shaped evaporation component 3 are in an open state. For example, all the dampers 13 on the opposite second side 12 are in an open state, so that the location of the second side 12 forms an air inlet 4.

[0108] This embodiment allows the airflow to enter from the air inlet 4 and flow directly into the flow channel between adjacent evaporation components 3, or into the channel between the second side 12 and the evaporation component 3. After evaporation by fully contacting the large surface of the evaporation component 3, the airflow passes directly through the partition 5 and flows upward through the fan 2 to be discharged from the container 1. This air inlet method combined with the arrangement of the evaporation components 3 can minimize airflow resistance, reduce the energy consumption of the evaporation device, and allow the airflow to circulate efficiently, thereby improving the evaporation efficiency.

[0109] In some embodiments, as shown in FIG5, the air inlets 4 facing the front of the plurality of evaporation components 3 are in an open state, and each evaporation component 3 is provided with a ventilation hole 31. For example, multiple ventilation holes 31 may be provided, and the ventilation holes 31 on adjacent evaporation components 3 may be arranged facing each other or staggered. The ventilation holes 31 may be round holes, polygonal holes, etc., and are not limited here.

[0110] In this embodiment, the air inlet 4 facing the front of the evaporator 3 is in an open state, so that the airflow can directly and vertically reach the surface of the evaporator 3 after entering, which increases the surface of the evaporator 3 participating in evaporation. On this basis, the evaporator 3 is provided with ventilation holes 31, so that the airflow can reach the evaporator 3 behind it after entering, so that all evaporators 3 can play a better evaporation role and reduce the flow resistance of the gas.

[0111] In some embodiments, the evaporation component 3 is in the form of a sheet, a cylinder, a mesh, or a rolled and folded shape.

[0112] In this embodiment, the use of sheet-shaped evaporation component 3 can achieve a larger evaporation surface area and facilitates installation and disassembly; the use of cylindrical or mesh-shaped evaporation component 3 can result in a larger specific surface area per unit volume and better gas flow performance; the use of rolled and folded evaporation component 3 has a stronger ability to adhere to liquids, and the rolled and folded shape can also increase the evaporation surface area.

[0113] In some embodiments, as shown in FIG6, multiple partitions 5 are provided, and multiple partitions 5 are spaced apart along a first direction x perpendicular to the first side 11. The evaporation components 3 are plate-shaped, and multiple evaporation components 3 are disposed on the multiple partitions 5. For example, the fan 2 is disposed on the top of the housing 1, the partitions 5 are placed horizontally, and the multiple partitions 5 are spaced apart along the height direction. For example, multiple evaporation components 3 are disposed in a one-to-one correspondence with multiple partitions 5.

[0114] This embodiment uses multiple partitions 5 spaced apart, and multiple evaporation components 3 are respectively placed on the partitions 5. There is no need to connect the evaporation components 3 to the partitions 5, making it easy to remove the evaporation components 3 and recover the salt after salt separation. After the airflow enters from the air inlet 4, it can reach the evaporation components 3 simultaneously from both the top and bottom sides of the partitions 5. Furthermore, after reaching the evaporation components 3 on the bottom partition 5, the airflow can continue to flow upwards step by step, enhancing the evaporation effect.

[0115] In some embodiments, as shown in FIG3, the inner sidewall of the accommodating member 1 is provided with a plurality of sets of mounting plates 6 at intervals along a first direction x perpendicular to the first side 11, and the partition 5 is configured to be selectively mounted on one of the sets of mounting plates 6.

[0116] For example, for a cuboid container 1, each set of mounting plates 6 may include four mounting plates 6, which are respectively located at the four corners of the container 1.

[0117] For example, the partition 5 can be placed on a set of mounting plates 6, or the mounting plates 6 have slots into which the partition 5 is embedded.

[0118] This embodiment allows for adjustment of the mounting height of the partition 5 by arranging multiple sets of mounting plates 6 along the first direction x. For example, multiple evaporation components 3 are suspended in the space below the partition 5. If liquid is obtained by self-priming, the mounting height of the partition 5 can be set according to the water lifting height of the evaporation component 3 material, so that the liquid at the bottom can reach the top of the evaporation component 3. If the water lifting height is large, or if liquid can be supplied by external power, the partition 5 can be installed at a higher position to increase the area of ​​the evaporation component 3. Furthermore, multiple sets of mounting plates 6 can be spaced apart within the housing 1 to support different evaporation components 3. This makes the installation method of the evaporation component 3 more flexible.

[0119] In some embodiments, as shown in FIG4, the fluid supply component includes:

[0120] First liquid storage container 8, which contains liquid; and

[0121] The first pump 9, whose outlet is connected to a spray pipe, is configured to supply liquid in the first storage container 8 to the evaporation unit 3 through the spray pipe.

[0122] Both the first liquid storage container 8 and the first pump 9 can be located outside the housing 1 to save space within the housing 1 for accommodating more evaporation components 3. The first pump 9 can be a peristaltic pump or the like. The inlet of the first pump 9 is connected to the first liquid storage container 8, and the outlet is connected to a spray pipe. The spray pipe can be equipped with multiple spray heads to supply liquid to different evaporation components 3. Preferably, the spray pipe can spray liquid onto the top of the evaporation component 3, so that the liquid can cover the entire surface of the evaporation component 3.

[0123] This embodiment uses an external driving force to spray liquid onto the evaporation component 3, ensuring a continuous and stable supply of liquid. The spray pipes can also evenly distribute the liquid to the evaporation component 3, making the evaporation process smooth and stable. The first pump 9 should be operated at an appropriate speed according to the evaporation process. If the speed is too high, the liquid supplied will exceed the evaporation rate, resulting in energy waste; if the speed is too low, the liquid supplied will be insufficient, failing to fully utilize the evaporation capacity of the evaporation component 3.

[0124] In some embodiments, as shown in Figures 3 and 4, the fluid supply component further includes:

[0125] The second liquid storage container 10, located at the inner bottom of the housing 1, is configured to receive excess liquid from the evaporation unit 3; and

[0126] The second pump is configured to pump the liquid in the second liquid storage container 10 to the evaporation unit 3 via an internal circulation pump.

[0127] The second liquid storage container 10 may be equipped with a handle on its outer side, making it easy to pull out like a drawer to clean the liquid.

[0128] In this embodiment, during the process of supplying liquid to the evaporation component 3 via the first pump 9, it is difficult to ensure that the supply amount does not exceed the evaporation amount, and some liquid inevitably fails to fall onto the evaporation component 3. By providing a second liquid storage container 10, excess liquid can be collected. Based on this, the liquid in the second liquid storage container 10 can be pumped to the evaporation component 3 by the second pump, allowing the fallen liquid to evaporate further.

[0129] In some embodiments, the fluid supply component includes a first liquid storage container 8 disposed at the inner bottom of the container 1, the first liquid storage container 8 containing liquid, and the evaporation component 3 configured to obtain liquid from the first liquid storage container 8 by self-priming.

[0130] This embodiment eliminates the need for an external power source, relying directly on the capillary action of the evaporation component 3 to absorb the liquid in the first liquid storage container 8, which simplifies the structure of the evaporation device and reduces costs.

[0131] In some embodiments, the evaporation component 3 is made of textile materials, metal, sponge, or rope mesh, etc. The evaporation material 3 can be either natural or synthetic. For example, textile materials are more economical; non-woven fabrics, cotton fabrics, or polyester can be selected, and they also have good evaporation performance as a carrier for moisture flow and evaporation.

[0132] In some embodiments, the evaporation apparatus further includes: a temperature control component configured to regulate the temperature within the containment space; and / or a humidity control component configured to regulate the humidity within the containment space.

[0133] For example, the temperature control component can be a heater located on the housing 1, or if the housing 1 is made of a thermally conductive material, the temperature control component can be located on the outer wall of the housing 1, and heat can be transferred to the housing space through the housing. The humidity control component can be a dehumidifier located outside the housing 1, which extracts moisture from the housing space through pipes.

[0134] This embodiment, by incorporating a temperature control component, can adjust the evaporation rate according to actual evaporation requirements (e.g., salt separation requirements), thereby achieving the target evaporation rate. For example, increasing the temperature is beneficial for increasing the evaporation rate. And / or by incorporating a humidity control component, the humidity inside the containment space can be adjusted according to actual evaporation requirements to achieve the target evaporation rate. For example, decreasing the humidity inside the containment space is beneficial for increasing the evaporation rate. Therefore, by incorporating both temperature and humidity control components, the containment space where the evaporation component 3 is located can be controlled to achieve the desired evaporation rate.

[0135] In some specific embodiments, the evaporation component 3 is placed horizontally or at a certain angle and suspended. The length of the evaporation component 3 is 10cm-40cm, the width is 1cm-40cm, the number of material layers suspended or laid flat is 1-10, the material shape is one or more of sheet, cylindrical, mesh or rolled and folded, the material pore size is one or more of micropore, mesopore, mesopore or macropore, the material weaving method is one or more of twill weave, plain weave, and intermittent weave, the material preparation method is one or more of casting, 3D printing, machine weaving or woven weaving, the material property is hydrophilic or hydrophobic, the humidity range is 10%-90%, and the wind speed range is 0-10m / s.

[0136] In application, the following technical solution is used: The wetted evaporation component 3 is suspended for a certain period until no more liquid drips from the bottom. Then, the evaporation component 3 is suspended or placed flat on the partition 5, and the liquid is transported via self-priming or the first pump 9 and spray pipes. The liquid level, temperature, and relative humidity are recorded, and an infrared thermal imager is used to observe and record the surface temperature of the material and the liquid transport. Data is recorded periodically until the evaporation rate stabilizes.

[0137] The evaporation apparatus disclosed herein has at least the following beneficial effects:

[0138] 1. By introducing wind energy as the driving force for efficient evaporation, compared with traditional thermal evaporation technology, wind-driven evaporation can effectively reduce energy consumption, decrease dependence on traditional energy sources, and reduce the carbon footprint of water treatment processes. It can also be promoted and applied in energy-scarce areas, driving the development of concentrated brine treatment technology towards low cost and sustainability. This technological breakthrough will provide new solutions for the resource-based treatment of industrial wastewater and brine, and has broad application prospects.

[0139] 2. By setting up an axial flow fan, a housing 1, and an evaporation component 3, the axial flow fan operates at high speed to draw in outside air, which then carries away the moisture on the surface of the evaporation component 3. An economical evaporation material (e.g., textile material) serves as the carrier for moisture flow and evaporation. At the same time, the evaporation performance can be optimized by adjusting the wind speed and direction. It features high evaporation efficiency, small footprint, and low energy consumption.

[0140] 3. By adjusting the temperature, humidity, wind speed, and wind direction according to different environmental conditions, the water evaporation efficiency of the evaporation material can be improved. The evaporation component 3 has multiple adaptability and can adjust the placement method, type, and shape according to the liquid and environmental conditions, which is conducive to improving the service life of the material and reducing system maintenance costs.

[0141] In some embodiments, the evaporation apparatus of this disclosure further includes a condensing component configured to condense the gas stream discharged from the evaporating containment 1 into a liquid for collection.

[0142] For example, if fan 2 is used for blowing air, fan 2 is located inside the housing 1, or fan 2 is located outside the housing 1 with its outlet connected to the air inlet 4, and the condenser is located downstream of the air outlet of the housing 1. If fan 2 is used for drawing air, fan 2 is located inside the housing 1, and the condenser is located downstream of the air outlet of the housing 1. If fan 2 is used for drawing air, fan 2 is located outside the housing 1 with its inlet connected to the air outlet, and the condenser is located downstream of the fan outlet.

[0143] This embodiment uses a condensation device to cool the airflow discharged from the fan 2, condensing it into liquid for liquid collection.

[0144] Secondly, this disclosure provides a salt separation system, which in some embodiments includes a salt separation device and an evaporation device as described in the above embodiments. The salt separation device is configured to separate solid salt or a concentrated solution of salt from the evaporation component 3. This embodiment, by providing the salt separation device, can separate solid salt from the evaporation component 3.

[0145] Furthermore, this disclosure proposes a salt separation method based on the evaporation apparatus of the above embodiments, which in some embodiments includes:

[0149] Obtain the evaporation parameters during the evaporation process, and adjust the speed of the fan 2 and / or the liquid supply speed of the fluid supply component according to the evaporation parameters until the evaporation rate stabilizes.

[0150] The evaporation component 3 can be connected to a suitable position within the housing 1, for example, to the wall or frame of the housing 1; or the evaporation component 3 can be placed on the partition 5, whereby the evaporation component 3 can be first connected to the partition 5 and then installed as a whole within the housing 1, or the partition 5 can be first installed within the housing 1 and then the evaporation component 3 placed on the partition 5. When the fluid supply component includes the first pump 9, the starting sequence of the first pump 9 and the fan 2 is not restricted.

[0151] This embodiment can acquire evaporation parameters reflecting evaporation performance during the evaporation process and adjust the rotation speed of the fan 2 and / or the liquid supply speed of the fluid supply components, such as the rotation speed of the first pump 9, to keep the evaporation rate stable, thereby ensuring stable operation of the evaporation device. For the same device, the corresponding rotation speed of the fan 2 and / or the liquid supply speed of the fluid supply components can be obtained even when the temperature is different in winter and summer or when the liquid is different, improving versatility.

[0152] In some embodiments, the evaporation parameters include: the surface temperature of the evaporation component 3 and the liquid transport status acquired by an infrared thermal imager; and / or

[0153] The fluid supply component includes: a first liquid storage container 8 containing liquid; and a first pump 9, the outlet of which is connected to a spray pipe. The first pump 9 is configured to supply the liquid in the first liquid storage container 8 to the evaporation component 3 through the spray pipe. Evaporation parameters include: the liquid level in the first liquid storage container 8, the liquid temperature, and the relative humidity. The liquid level in the first liquid storage container 8 reflects the amount of water evaporated per unit time, while the liquid temperature and relative humidity both affect the evaporation rate.

[0154] This embodiment can acquire and record evaporation parameters at regular intervals. In the early stages of the evaporation process, the evaporation parameters can be adjusted to stabilize the evaporation rate. After the evaporation stabilizes, the evaporation performance can be monitored.
