Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0039] In this embodiment, as Figure 1 and Figure 3 As shown, a foam suppression device for an evaporation system includes: an evaporator body 1; the foam suppression device includes: an internal annular tube 2 disposed in the inner cavity of the evaporator body 1; a guide tube 3 for conveying defoamer, the guide tube 3 being located on the central axis of the internal annular tube 2, the bottom end of the guide tube 3 being connected to multiple branch tubes 31, the ends of the multiple branch tubes 31 away from the guide tube 3 being connected to the internal annular tube 2, the multiple branch tubes 31 being evenly distributed based on the inner circle of the internal annular tube 2; and circular holes 31a being opened on the outer periphery of the multiple branch tubes 31, the circular holes 31a being evenly distributed along the axis of the branch tubes 31.

[0040] Therefore, after the defoamer is introduced into the guide tube 3, the defoamer is split at the bottom of the guide tube 3 and enters the branch tube 31. Some of the defoamer is sprayed onto the boiling liquid surface through the round hole 31a of the branch tube 31. Since there are multiple branch tubes 31 and they are evenly distributed based on the guide tube 3, the defoamer is evenly sprayed onto the boiling liquid surface to increase the defoaming effect on the boiling liquid surface.

[0041] Specifically, the interior of the built-in annular tube 2 is hollow to facilitate the flow of defoamer. The outer diameter of the built-in annular tube 2 is smaller than the inner diameter of the evaporator body 1 to facilitate the installation of the built-in annular tube 2 in the inner cavity of the evaporator body 1. The outer wall of the guide tube 3 is machined with protrusions. The bottom end of the guide tube 3 is connected to the built-in annular tube 2 through four branch tubes 31. Each branch tube 31 has a round hole 31a. The round holes 31a are designed to be evenly distributed based on the axis of the branch tubes 31 to improve the uniformity of defoamer spraying.

[0042] Furthermore, there is no specific limit to the number of branch pipes 31 that can be used; they can be installed according to specific usage requirements.

[0043] In some embodiments, such as Figure 5 As shown, the guide pipe 3 is equipped with a rotating assembly 4, which is used to drive the guide pipe 3 to rotate, thereby driving multiple branch pipes 31 to dynamically spray defoamer; the rotating assembly 4 includes: a U-shaped frame 41, which is connected to the guide pipe 3 through bearings and connected to the evaporator body 1 through a connector 43; a driven gear 42, which is located in the U-shaped groove of the U-shaped frame 41, and the center hole of the driven gear 42 is fixedly connected to the guide pipe 3; and a driving member 44, which is used to drive the driven gear 42 to rotate.

[0044] Specifically, there are two bearing connection points between the U-shaped frame 41 and the guide tube 3. The protrusion on the outer wall of the guide tube 3 can be embedded in the groove of the U-shaped frame 41 so that the guide tube 3 will not fall out of the U-shaped frame 41. The driving component 44 drives the driven gear 42 to rotate so as to drive the guide tube 3 to rotate, and then the guide tube 3 drives the branch tube 31 and the built-in annular tube 2 to move.

[0045] In some embodiments, such as Figure 5 As shown, the driving component 44 includes: a vertical rod 441, which is connected to the U-shaped frame 41 via a bearing, and a servo motor 441a is disposed at the top of the vertical rod 441; a driving gear 442, the center hole of the driving gear 442 is fixedly connected to the vertical rod 441, and the outer periphery of the driving gear 442 is meshed with the driven gear 42.

[0046] Specifically, the vertical rod 441 can rotate in the U-shaped frame 41, the servo motor 441a is connected to the vertical rod 441 through a coupling, the servo motor 441a is fixed on the protrusion of the U-shaped frame 41, and the drive gear 442 drives the driven gear 42 to rotate when the drive gear 442 rotates.

[0047] In some embodiments, such as Figure 6As shown, the connector 43 includes: a slide rod 431, one end of which is fixedly connected to the U-shaped frame 41, and the other end of which is inserted into a sliding shell 432. A connecting plate 433 is fixedly connected to the end of the sliding shell 432 away from the slide rod 431. The connecting plate 433 is connected to the evaporator body 1 by bolts 433a. A positioning pin 432a is arranged in the sliding groove of the sliding shell 432, and the slide rod 431 is connected to the sliding shell 432 by the positioning pin 432a.

[0048] Specifically, the sliding shell 432 is machined with a sliding groove, the sliding rod 431 can move laterally in the sliding shell 432, and two positioning pins 432a are designed to increase the connection strength between the sliding rod 431 and the sliding shell 432. The connecting plate 433 is adapted to the inner wall of the evaporator body 1.

[0049] In some embodiments, such as Figure 2 As shown, the bottom end of the built-in annular tube 2 is provided with a liquid outlet 21, and a nozzle 22 is arranged in the liquid outlet 21.

[0050] Specifically, the number of liquid outlets 21 is matched with the number of nozzles 22 used, and the liquid outlets 21 are used to connect with the nozzles 22.

[0051] In some embodiments, such as Figure 4 As shown, nozzle 22 is trumpet-shaped;

[0052] Specifically, the nozzle 22 is designed in a trumpet shape for spraying defoamer.

[0053] In some embodiments, such as Figure 4 As shown, the nozzles 22 are uniformly distributed based on the built-in annular tube 2;

[0054] Specifically, the design of multiple nozzles 22 facilitates the spraying of defoamer onto the contact point between the edge of the liquid surface and the evaporator body 1.

[0055] In some embodiments, such as Figure 4 As shown, the top of the guide pipe 3 is equipped with a liquid inlet pipe 5. The liquid inlet end of the liquid inlet pipe 5 is connected to the evaporator body 1, and the liquid outlet end of the liquid inlet pipe 5 is connected to the guide pipe 3 through a bearing.

[0056] Specifically, the inlet pipe 5 is connected to an external defoamer pipe for transmitting defoamer. The outlet end of the inlet pipe 5 is connected to the guide pipe 3 via a bearing, so that the rotation of the guide pipe 3 will not cause the inlet pipe 5 to rotate.

[0057] In some embodiments, such as Figure 4 As shown, the liquid inlet pipe 5 is a retractable plastic pipe.

[0058] Specifically, part of the liquid inlet pipe 5 is designed as a retractable plastic tube so that after the liquid inlet pipe 5 and the guide pipe 3 are connected, it can be discharged from the evaporator body 1.

[0059] In some embodiments, such as Figure 6 As shown, bolt 433a is distributed in a ring based on connecting disc 433.

[0060] The design of multiple bolts 433a increases the connection strength between the connecting plate 433 and the evaporator body 1.

[0061] The working principle of this application is illustrated below with a preferred embodiment:

[0062] First, install the built-in annular tube 2 in the inner cavity of the evaporator body 1. Move the sliding shell 432 on the outer wall of the sliding rod 431. The connecting plate 433 on the sliding shell 432 abuts against the evaporator body 1. Then, use bolts 433a to fix the connecting plate 433 to the inner wall of the evaporator body 1. Then, use positioning pins 432a to fix the position of the sliding rod 431 in the sliding shell 432. Next, connect the liquid inlet pipe 5 to the top of the guide pipe 3.

[0063] When the material in the evaporator body 1 undergoes intense heating, flashing, and boiling during the evaporation process, the external pump introduces defoamer into the guide pipe 3 through the liquid inlet pipe 5. The defoamer is split at the bottom of the guide pipe 3 and enters the branch pipe 31. Part of the defoamer is sprayed onto the boiling liquid surface through the round hole 31a for defoaming treatment, while the other part of the defoamer enters the built-in annular pipe 2 along the branch pipe 31. The defoamer enters the nozzle 22 along the liquid outlet 21 of the built-in annular pipe 2 and is sprayed onto the contact position between the material liquid surface and the evaporator body 1.

[0064] The servo motor 441a is started. The servo motor 441a drives the vertical rod 441 to rotate in the U-shaped frame 41 through the coupling. Then, the driving gear 442 on the vertical rod 441 drives the driven gear 42 to rotate. The driven gear 42 drives the guide tube 3 to rotate in the U-shaped frame 41. The top of the guide tube 3 rotates at the liquid outlet of the liquid inlet pipe 5. At the same time, the bottom of the guide tube 3 drives the branch pipe 31 and the built-in annular pipe 2 to rotate together. Thus, the defoamer is sprayed onto the boiling liquid surface in a planar motion state.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
