Description

Technical Field

[0001] This utility model relates to industrial wastewater treatment equipment, and more particularly to a heat pump distillation system. Background Technology

[0002] Currently, when treating ammonia-containing wastewater through a distillation system, the hot steam from the top of the distillation tower is heat-exchanged by a heat pump unit in the system, thereby absorbing the heat of the steam and releasing the heat during the compression process through a heat-conducting working fluid, so as to enter the reboiler to achieve secondary utilization of the heat.

[0003] As mentioned above, since hot steam usually contains residual foreign matter, during the condensation process, foreign matter tends to accumulate in the evaporator. Over time, this can affect the heat exchange efficiency of the condenser. For example, Chinese utility model patent CN215930199U disclosed a circulating condenser for heat pump distillation, which allows for the opening of its internal structure for easy cleaning. This utility model will provide a heat pump distillation system based on the existing technology, thereby providing a further solution to the problem of foreign matter presence.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] This invention provides a heat pump distillation system. Unlike existing distillation systems, the system in this invention includes a heat exchange structure that replaces the condenser in existing systems. Specifically, as shown in the example... Figure 1-3 As shown, the heat exchange structure includes an insulated box 1, which has an inlet 2 and an outlet 3 for steam to enter and exit respectively, so that the insulated box 1 is connected in series in the hot steam recovery path.

[0028] Furthermore, the insulation box 1 is also equipped with a heat-conducting pipe 5. Specifically, the insulation box 1 is equipped with two pipe interfaces 4 that extend into its own interior. The heat-conducting pipe 5 is connected to the two pipe interfaces 4 through a movable structure (corrugated pipe 6) inside the insulation box 1. Through the two pipe interfaces 4, the heat-conducting pipe 5 can be connected in series in the flow path of the heat-conducting working fluid in the heat pump unit, so that the heat-conducting working fluid circulates through the heat-conducting pipe 5.

[0029] Furthermore, refer to Figure 2 and Figure 3 The insulation box 1 is also equipped with a wiping part 8 for wiping the outer surface of the heat-conducting pipe 5. A metal strip 9 is fixedly connected to the wiping part 8. The metal strip 9 is fixedly fastened to the inner wall of the insulation box 1 by a snap-fit ​​method, thereby keeping the wiping part 8 fixedly installed inside the insulation box 1. The shape of the heat-conducting pipe 5 is as follows: Figure 2 and Figure 3As shown, it is bent and flat, so that multiple support surfaces 7 are formed on the outer surface. By maintaining sufficient flatness of the heat pipe 5, the support surfaces 7 can account for at least 80% of the total outer surface area of ​​the heat pipe 5. The wiping part 8 is elastic and extends between two adjacent support surfaces 7, thereby supporting the heat pipe 5. Through the cooperation of multiple wiping parts 8 and multiple support surfaces 7, the heat pipe 5 is kept stably suspended in the heat preservation box 1.

[0030] Furthermore, such as Figure 1-3 As shown, an ultrasonic transducer 10 is also provided on the heat preservation box 1, and a rigid vibration guide plate 11 is fixedly connected to the heat conduction pipe 5. The output end of the ultrasonic transducer 10 is fixedly connected to the vibration guide plate 11.

[0031] When the system is working, the heat-conducting medium passes through the heat pipe 5, and the steam passes through the insulation box 1, thereby completing the heat exchange between the two. During this process, the ultrasonic transducer 10 works, so that the heat pipe 5 obtains vibration energy and performs high-frequency activity, thereby maintaining high-frequency friction with the wiping part 8 to reduce or prevent the accumulation of foreign objects on the surface of the heat pipe 5, thereby maintaining good cleanliness of the surface of the heat pipe 5 and maintaining good heat exchange efficiency. Moreover, compared with the existing technology, this structure makes it difficult for foreign objects to accumulate on the heat pipe 5, so they are easily carried away with the condensate after condensation, thus reducing the number of maintenance times.

[0032] Regarding the structure of the wiping section 8, such as Figure 4 and Figure 5 As shown, it has a woven structure, specifically made of woven metal wires. This structure makes the whole semi-flexible, so that it can form good contact with the two support surfaces 7, while not completely blocking the support surfaces 7, thus maintaining good contact between the support surfaces 7 and the steam.

[0033] Furthermore, the insulated box 1 is also equipped with an opening that can be opened (located in...). Figure 1 On the other side of the view (not shown in the attached diagram), through the opening and the locking mechanism between the metal strip 9 and the inner wall of the fish insulated box 1, the wiping part 8 can still be disassembled for maintenance or replacement.

[0034] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
