Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a water injection point module. Background Technology

[0002] The water-for-injection (FCI) module is a crucial component of pharmaceutical water systems. It is responsible for directly delivering high-quality FCI to various process water points. FCI typically requires storage at relatively high temperatures (above 80°C) to reduce the risk of microbial growth. Depending on the specific process and product requirements, the temperature of the FCI needs to be adjusted.

[0003] Currently, cooling media are often installed outside the delivery pipeline to adjust the temperature of the injection water through heat exchange. To ensure efficient and uniform heat transfer from the injection water to the cooling medium, theoretically, the thermal boundary layer of the injection water fluid inside the pipeline should be as thin as possible and fully mixed. If the diameter of the delivery pipeline is too large, a heat exchange dead zone may easily appear in the middle of the pipeline, resulting in uneven heat exchange and affecting the heat exchange quality. On the other hand, reducing the diameter of the delivery pipeline to ensure heat exchange quality may reduce the delivery efficiency of the injection water.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0041] Please see Figure 1 and Figure 2This embodiment proposes a water injection point module, which includes a first delivery pipeline 1, a first valve 2, a heat exchange pipe 3, a second valve 4, and a third valve 5. The first delivery pipeline 1 is used to deliver water for injection; the first valve 2 is disposed in the first delivery pipeline 1 and is used to control the opening and closing of the first delivery pipeline 1; the heat exchange pipe 3 includes a first pipe 31, a second pipe 32, and a third pipe 33 arranged sequentially from the inside to the outside, wherein the first pipe 31 and the third pipe 33 are both used to contain cooling medium, and the second pipe 32 is connected to the first delivery pipeline 5. The delivery pipeline 1 has the same diameter. The inlet and return ends of the second pipeline 32 are both connected to the first delivery pipeline 1 to form a first circulation loop. The second valve 4 is located between the inlet end and the first delivery pipeline 1 to control the injection water to enter the first circulation loop. The third valve 5 is located between the return end and the first delivery pipeline 1 to control the injection water to flow back to the first delivery pipeline 1. Along the delivery direction of the first delivery pipeline 1, the second valve 4 is located upstream of the first valve 2, and the third valve 5 is located downstream of the first valve 2.

[0042] It is understandable that during the heat exchange process of the injection water, closing the first valve 2 and opening the second valve 4 and the third valve 5 allows the injection water to be transported from the first delivery pipeline 1 to the first circulation loop. Under the action of the cooling medium in the first pipeline 31 and the third pipeline 33, the injection water in the second pipeline 32 can undergo bidirectional heat exchange, thereby ensuring the heat exchange quality while increasing the diameter of the first delivery pipeline 1 to ensure the injection water delivery rate.

[0043] In practical applications, a delivery pump is installed on the first delivery pipeline 1, and the first valve 2 is located at the outlet of the first delivery pipeline 1. When heat exchange of the injection water is not required, the first valve 2 is opened, and the second valve 4 and the third valve 5 are closed. Under the action of the first delivery pipeline 1, the injection water can be directly output. The first valve 2, the second valve 4 and the third valve 5 are preferably automatic plunger valves, so that the staff can control the opening and closing of the pipeline and accurately control the delivery flow rate of the injection water.

[0044] Furthermore, the first pipe 31, the second pipe 32, and the third pipe 33 are arranged in a U-shape. This arrangement extends the flow time of the injected water in the second pipe 32, thereby further ensuring the quality of heat exchange.

[0045] In this embodiment, the heat exchange tube 3 further includes a second delivery pipe 34 and a delivery pump disposed on the delivery pipe. Under the action of the delivery pump, the second delivery pipe 34 can deliver the cooling medium, and both ends of the second delivery pipe 34 are respectively connected to the first pipe 31 and the third pipe 33 to form a second circulation loop. It can be understood that each end of the second delivery pipe 34 has two connection ports, which are respectively connected to the first pipe 31 and the third pipe 33. During the heat exchange process, the second delivery pipe 34 can deliver the cooling medium to the first pipe 31 and the second pipe 32. Under the action of the delivery pump, the cooling medium can circulate in the second circulation loop to ensure that the temperature of the cooling medium is maintained at the initial temperature, thereby further ensuring the heat exchange quality.

[0046] In addition, the injection water point module also includes a fourth valve 6, which is located in the second delivery pipeline 34 to control the opening and closing of the second delivery pipeline 34. It is understood that when heat exchange of the injection water is not required, disconnecting the second delivery pipeline 34 via the fourth valve 6 can prevent cooling medium from entering the first pipeline 31 and the third pipeline 33, thereby avoiding waste.

[0047] In this embodiment, the heat exchange tube 3 further includes a first transfer box 7 and a first transfer pipe 8. The first transfer box 7 is connected to the liquid inlet end, and the first pipe 31 passes through the first transfer box 7. The first transfer pipe 8 is used to connect the first transfer box 7 and the first delivery pipe 1. It can be understood that the injection liquid delivered by the first delivery pipe 1 is delivered to the first transfer box 7 and can enter the second circulation loop through the first transfer box 7 to start heat exchange. Under the action of the first pipe 31, the injection liquid in the first transfer box 7 can be separated from the cooling medium in the first pipe 31 to facilitate heat exchange.

[0048] Specifically, the first transfer pipe 8 has a Y-shaped first connecting branch pipe 81, a second connecting branch pipe 82, and a third connecting branch pipe 83. The first connecting branch pipe 81 is connected to the first delivery pipeline 1, and a second valve 4 is installed on the first connecting branch pipe 81. The second connecting branch pipe 82 is connected to the first transfer box 7. The injection water point module also includes a third delivery pipeline 9, which is connected to the third connecting branch pipe 83 and forms a third circulation loop with the first delivery pipeline 1. It can be understood that when the first delivery pipeline 1 stops delivering injection water, the first valve 2 is closed, the second valve 4 is opened, and the third valve 5 is closed. Under the action of the delivery pump, the injection water can circulate in the third circulation loop, relying on the temperature of the injection water itself to sterilize the first delivery pipeline 1, thus preventing bacterial growth in the injection water if it remains stationary for a long time.

[0049] Furthermore, the second connecting branch pipe 82 and the third connecting branch pipe 83 form a convex pipe facing the first conveying pipeline 1. This arrangement reduces the length of the first connecting branch pipe 81, thereby preventing stagnant water at the connection points of the first connecting branch pipe 81, the second connecting branch pipe 82, and the third connecting branch pipe 83, thus further ensuring hygiene in the entire third circulation loop.

[0050] In this embodiment, the heat exchange tube 3 further includes a second transfer box 10 and a second transfer pipe 11. The second transfer box 10 is connected to the return end, and the first pipe 31 passes through the second transfer box 10. One end of the second transfer pipe 11 is connected to the second transfer box 10, and the other end is connected to the first pipe 31. It can be understood that the injection water enters the second transfer box 10 through the return end and flows back to the first delivery pipeline 1 through the second transfer pipe 11. The third valve 5 is provided on the second transfer pipe 11 to control the opening and closing of the second transfer pipe 11. The structure of the second transfer box 10 is the same as that of the first transfer box 7, and will not be described in detail here.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
