[0002] In conventional evaporation system and MVR evaporation system, the connecting channel between heater and evaporation chamber is only a relatively short small-diameter pipe, this small-diameter pipe can only play the role of conveying fluid, and fills its entire cross section when fluid flows through it, so there is no space for fluid evaporation, that is, this small-diameter pipe can only play the role of conveying fluid from the heater to the evaporation chamber to assist subsequent evaporation and concentration in the evaporation chamber. Therefore, it can be seen that the evaporation process in the existing scheme can only occur in the evaporation chamber, and the space in the evaporation chamber is limited, but the space for gas expansion in the evaporation chamber is limited, which results in slow evaporation speed.

[0022] The core of the present application is to provide a heating and evaporation system, which can make the water molecules in the fluid have a larger surface area and evaporation space when passing through the fluid passage between the heating device and the evaporation device, so that the fluid molecules can quickly separate from the liquid surface to form flash evaporation, thereby improving the overall evaporation speed of the system.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] An embodiment of the heating and evaporation system provided by the present application is shown in the figure. Figure 1 、 Figure 2 and Figure 3 An embodiment of the heating and evaporation system provided by the present application is shown in the figure. Figure 1 An embodiment of the heating and evaporation system provided by the present application is shown in the figure. Figure 2 An embodiment of the heating and evaporation system provided by the present application is shown in the figure. Figure 3 A cross section of a fluid passage of an embodiment of the heating and evaporation system provided by the present application is shown in the figure. The heating and evaporation system can include:

[0025] The heating device 1 has a fluid outlet 11. It should be noted that the heating device 1 can be a plate heat exchanger or a tube heat exchanger, and of course other types of heating devices can be selected according to actual needs, which are not limited here. That is, a plurality of types of heating devices can be connected to the evaporation device by using the structure provided in the present embodiment, and the fluid outlet 11 is used to flow out the fluid after heating;

[0026] Evaporation device 2 has a fluid inlet 21. It should be noted that the evaporation device 2 can be an evaporation device in a general evaporation system, an evaporation device in an MVR (Mechanical Vapor Recompression) evaporation system, or an evaporation device in other types of evaporation systems. There are no limitations here. That is to say, various types of evaporation devices can be connected to the heating device using the structure provided in this embodiment. The fluid inlet 21 is used to allow the heated fluid to flow into the evaporation device 2 for subsequent evaporation and concentration processes.

[0027] The fluid channel 3 has a first end connected to the fluid outlet 11 and a second end connected to the fluid inlet 21, thus allowing the heated fluid flowing out of the heating device 1 to be transported into the evaporation device 2. The lower part of the cross-section of this fluid channel 3 is the fluid flow space 31, and the upper part is the evaporation space 32. It should be noted that... Figure 3 As can be seen, the area below the horizontal dotted line is the fluid flow space 31. Under the influence of gravity, the heated fluid will definitely flow through this fluid channel 3 from the bottom. This means the fluid can flow within the fluid flow space 31. The area above the horizontal dotted line is the evaporation space 32. This design preserves the space that allows the evaporated steam to pass through. Since the evaporated steam naturally rises, this evaporation space 32 is located above the fluid flow space 31. This means the flowing fluid will not exceed the height of the horizontal dotted line, while the evaporation space 32 above the horizontal dotted line remains empty. As the fluid flows within the fluid flow space 31, its upper surface continuously releases steam into the evaporation space 32, thus achieving flash evaporation within the fluid channel 3. This means that the fluid can evaporate in the fluid channel 3 before entering the evaporation device 2. Furthermore, the evaporation space 32 is directly connected to the evaporation device 2, allowing the steam evaporated in the fluid channel 3 to directly enter the evaporation device 2 through the evaporation space 32. Therefore, evaporation occurs both within the fluid channel 3 and the evaporation device 2, increasing the evaporation time and thus improving the overall evaporation rate of the system. It should also be noted that... Figure 3The cross section of the fluid passage 3 is only schematically shown, but in fact, the cross section of the fluid passage 3 is not limited to this, and can be selected in many other shapes according to actual needs, and the height of the lateral dashed line can also be adaptively adjusted according to actual needs, for example, when the flow of the fluid is small, the height of the lateral dashed line is low, that is, the upper surface of the fluid flow space 31 is low, and conversely, when the flow of the fluid is large, the height of the lateral dashed line is high, that is, the upper surface of the fluid flow space 31 is high, and of course, as long as the evaporation space 32 still exists, the evaporation process in the fluid passage 3 can be realized.

[0028] It should be further pointed out that the fluid passage 3 can be used to connect the primary heater and the primary evaporator, or the secondary heater and the secondary evaporator, and can ensure sufficient fluid flow space and evaporation space required for fluid molecules to escape from the liquid surface, thereby improving the evaporation efficiency and reducing the overall system footprint.

[0029] As can be seen from the above technical solutions, in the embodiment of the heating and evaporation system provided by the present application, the heating device has a fluid outlet, the evaporation device has a fluid inlet, the fluid passage has a first end in communication with the fluid outlet and a second end in communication with the fluid inlet, the lower part of the cross section of the fluid passage is a fluid flow space, and the upper part is an evaporation space, so that the water molecules in the fluid have a larger surface area and evaporation space when passing through the fluid passage between the heating device and the evaporation device, and thus can rapidly escape from the liquid surface to form flash evaporation, and can perform flash evaporation while flowing in the fluid passage, thereby improving the overall evaporation speed of the heating and evaporation system.

[0030] In one embodiment of the heating evaporation system, the cross-sectional side of the evaporation space 32 in the fluid channel 3 is not tapered from bottom to top. It should be noted that there are two cases, the first case is that the cross-sectional side of the evaporation space 32 in the fluid channel is tapered from bottom to top, that is, the side extends outwardly and upwardly from bottom to top, so that the space becomes larger and larger as it goes upward, so that the space that can be diffused becomes larger and larger during the upward evaporation of the steam, so that the evaporation speed can be accelerated and the steam can move faster into the evaporation device, the second case is that the cross-sectional side of the evaporation space 32 is parallel and unchanged from bottom to top, so that the evaporation path of the steam is not hindered during the upward movement of the steam, so as to ensure that the evaporation speed of the steam is fast enough, of course, the cross-section of the evaporation space 32 can be selected according to actual needs, which is not limited here. It should be noted that the factors affecting the evaporation speed include temperature, humidity, surface area of the liquid, air flow speed above the liquid surface, etc. The higher the temperature, the faster the evaporation, because at any temperature, molecules are constantly moving, and some molecules with high speed in the liquid can fly out of the liquid surface to become vapor molecules, so the liquid can evaporate at any temperature, if the surface area of the fluid increases, the number of molecules near the surface of the fluid increases, so the number of molecules flying out of the surface of the fluid increases in the same time, so the larger the area of the upper surface of the fluid, the faster the evaporation speed, if the air flow speed above the fluid is fast, the ventilation is good, the opportunity for molecules to return to the fluid is small, so the evaporation is faster, the fluid channel shape used in the prior art is a small-diameter circular pipe, which not only has a small cross-sectional area, but also can only accommodate fluid passing through, and cannot realize evaporation in the channel, and the area near the top is tapered from bottom to top, so even if a certain evaporation space appears in the fluid flow near the top, due to the small evaporation surface area and the tapered structure, it is difficult to realize flash evaporation in the fluid channel, it can be seen that the embodiment of the present application solves the problems existing in the prior art by improving the cross-sectional shape of the evaporation space. On the basis of this embodiment, the cross-section of the evaporation space in the fluid channel can be further optimized to be rectangular or square, and the specific length of the side can be selected according to actual needs, and such shape is more convenient to manufacture and has lower manufacturing cost.

[0031] In another embodiment, on the basis that the side of the cross section of the evaporation space 32 in the fluid channel 3 is tapered upwardly from the bottom, the side of the cross section of the evaporation space 32 in the fluid channel 3 can preferably be arc-shaped, that is, the side of the cross section can be tapered upwardly from the bottom in an arc-shaped manner, and the curvature can be selected according to actual needs. Compared with the tapered manner in a planar form, the tapered range can be larger, so that when the fluid surface height in the fluid flow space 31 is higher, the evaporation area can be increased by a larger range, so that the evaporation speed can be faster, and the volume of the evaporation space 32 at the upper part is larger, which can accommodate more steam, and the transportation speed of the steam can be improved, and the steam can be transported to the evaporation device faster, which can further increase the evaporation speed of the steam.

[0032] In yet another embodiment, on the basis that the cross section of the evaporation space 32 in the fluid channel 3 is preferably rectangular or square, the cross section of the fluid flow space 31 in the fluid channel 3 can be further preferably rectangular or square, and the sizes of the two cross sections can be preferably consistent, that is, the cross section shapes and sizes of the evaporation space 32 and the fluid flow space 31 are the same, and together form a rectangle or a square, so that the overall manufacturing can be facilitated, and the manufacturing efficiency can be improved. Of course, the sizes can be adaptively adjusted according to actual needs, which is not limited here.

[0033] In the various embodiments of the heating evaporation system described above, the cross section of the fluid outlet 11 of the heating device 1 and the cross section of the fluid passage 3 at the connection part of the fluid outlet 11 are preferably of the same shape and size; the cross section of the fluid inlet 21 of the evaporation device 2 and the cross section of the fluid passage 3 at the connection part of the fluid inlet 21 are preferably of the same shape and size. In a specific implementation, when the cross section of the fluid passage 3 at the connection part of the fluid outlet 11 is rectangular, the cross section of the fluid outlet 11 of the heating device 1 can also be selected to be rectangular, and the length and width of the two rectangles are consistent, so that the fluid can flow into the fluid passage 3 without any obstruction after flowing out of the fluid outlet 11 of the heating device 1, so that the fluid flows more smoothly and faster. When the cross section of the fluid passage 3 at the connection part of the fluid inlet 21 is rectangular, the cross section of the fluid inlet 21 of the evaporation device 2 can also be selected to be rectangular with the same length and width, so that the fluid can flow into the evaporation device 2 without any obstruction when flowing out of the fluid passage 3, so that the fluid also flows faster. In addition, the fluid outlet 11 and the fluid passage 3 can be preferably connected and fixed by flanges, and the fluid inlet 21 and the fluid passage 3 can also be connected and fixed by flanges, which not only ensures the safety during work and avoids leakage, but also makes it more convenient to disassemble when replacing related parts, thereby improving the efficiency of maintenance work

[0034] In further embodiments, continuing to refer to Figure 1 The fluid passage 3 preferably surrounds at least a part of the outer periphery of the evaporation device 2, that is, at least a part of the fluid passage 3 is connected to the inside of the evaporation device 3 after surrounding the outer periphery of the evaporation device 2, so that the fluid passage 3 is longer, the fluid flows in it for a longer time, and the evaporation time is further increased, the steam evaporated is more, and the evaporation effect is enhanced. Of course, the distance of the fluid passage 3 surrounding the outer periphery of the evaporation device 2 can be selected according to actual needs, for example, the fluid passage 3 surrounds the outer periphery of the evaporation device at least half a turn, or one turn, or close to one turn, or less than half a turn, as long as it can prolong a part of the fluid passage 3.

[0035] Further, the fluid passage 3 can preferably adopt a shape similar to a snail spiral, so that the fluid entering the evaporation device 2 forms a vortex and is ejected, rotates along the inner surface of the evaporation device 3, and evaporates in the process of rotation, which can further improve the evaporation path and evaporation time, ensure the flash evaporation surface area of the liquid entering the evaporation chamber, and further improve the evaporation effect, greatly improve the efficiency of the equipment, and reduce the overall equipment footprint.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application.
