[0021] 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.

[0022] 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 embodiment or an embodiment selectively excluded from other embodiments.

[0023] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present invention. This embodiment provides a high-efficiency heat exchanger, including a storage tank 1. A first connecting pipe 2 is fixedly connected to the bottom of the storage tank 1. A three-way connecting pipe 3 is fixedly connected to one end of the first connecting pipe 2. Both ends of the three-way connecting pipe 3 are fixedly connected to second connecting pipes 4. A hopper 5 is disposed above the storage tank 1. A connecting structure 28 is disposed at the top of the storage tank 1 and is connected to the hopper 5. Two limiting protrusions 11 are fixedly disposed on the outer side of the hopper 5. A horizontal plate 12 is disposed at the top of the hopper 5. Buckle plates 13 are fixedly disposed at both ends of the horizontal plate 12. 13 is engaged with the limiting protrusion 11. A clearing rod 14 is slidably arranged inside the horizontal plate 12. A pressing plate 15 is fixedly arranged on the top of the clearing rod 14. A spring 16 is sleeved on the outside of the clearing rod 14. A conical head 17 is fixedly arranged at the bottom of the clearing rod 14. A third connecting pipe 18 is fixedly connected to the bottom of the hopper 5. The third connecting pipe 18 is fixedly connected to the top of the storage tank 1. A fourth connecting pipe 19 is fixedly connected to the outside of the third connecting pipe 18. One end of the fourth connecting pipe 19 is fixedly connected to the pressurizing air source 20. A support structure 29 is arranged on the outside of the storage tank 1. During the DMTO reaction process, the second connecting pipe 4 is connected to the inlet of the external heat exchanger, and then the hopper 5 is installed above the storage tank 1 through the connecting structure 28. The hopper 5 is connected to the storage tank 1 through the third connecting pipe 18. Then, the horizontal plate 12 is installed on the top of the hopper 5 through the limiting protrusion 11 and the buckle plate 13. When the material is introduced into the storage tank 1 through the hopper 5, the hopper 5 is pressed back and forth, so that the unblocking rod 14 slides. The conical head 17 at the bottom of the unblocking rod 14 will unblock, thereby improving the flowability. Then, the pressurized air source 20 is activated to spray the solid calcium hydroxide particles inside the storage tank 1 into the heat exchanger through the second connecting pipe 4, thereby impacting the catalyst attached to the heat exchanger tube bundle, causing it to fall off, improving the heat exchanger efficiency, and at the same time avoiding water system fluctuations and water quality deterioration.

[0024] The connecting structure 28 includes multiple fixing plates 6, which are fixedly installed on the top of the storage tank 1. Each fixing plate 6 has a vertical rod 7 fixedly installed on its top. A threaded connecting rod 8 is fixedly installed on the top of the vertical rod 7. A threaded cap 9 is threadedly connected to the outside of the threaded connecting rod 8. Multiple mounting plates 10 are fixedly installed on the outside of the hopper 5. The threaded connecting rod 8 passes through the mounting plate 10. When the hopper 5 is installed on top of the storage tank 1, the mounting plate 10 on the outside of the hopper 5 is at the top of the vertical rod 7. The threaded connecting rod 8 at the top of the vertical rod 7 passes through the mounting plate 10, and then the threaded cap 9 is threadedly connected to the threaded connecting rod 8 to fix the hopper 5.

[0025] Example 2: Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0026] For example, the support structure 29 includes a plurality of support rods 21, which are fixedly installed on the outside of the storage tank 1. Each of the support rods 21 is threadedly connected to an adjusting rod 22. The top of the adjusting rod 22 is rotatably connected to an anti-slip plate 23. An annular plate 24 is fixedly installed on the top of the anti-slip plate 23. A sliding sleeve 25 is slidably installed on the outside of the adjusting rod 22. Two latches 26 are fixedly installed on the outside of the sliding sleeve 25 and are fastened inside the annular plate 24. Two limiting sliders 27 are fixedly installed inside the sliding sleeve 25 and are slidably installed on the inner wall of the adjusting rod 22. When the storage tank 1 is supported by the support rod 21, and the height of the storage tank 1 needs to be adjusted, slide the sliding sleeve 25 upward to separate the buckle 26 from the annular plate 24, rotate the adjusting rod 22 to adjust the height of the storage tank 1, and after the adjustment is completed, slide the sliding sleeve 25 downward to engage the buckle 26 with the annular plate 24 to limit the adjustment rod 22.

[0027] The inside of the buckle plate 13 is provided with a C-shaped buckle groove, and the limiting protrusion 11 is engaged with the C-shaped buckle groove. By engaging the buckle plate 13 with the limiting protrusion 11, the horizontal plate 12 is installed on the top of the hopper 5.

[0028] The mounting plate 10 has a through hole inside, through which the threaded connecting rod 8 passes. The hopper 5 is installed above the storage tank 1 by passing through the mounting plate 10 via the threaded connecting rod 8.

[0029] The annular plate 24 has multiple evenly spaced grooves inside, and the buckle 26 is fastened inside the grooves. By fastening the buckle 26 inside the annular plate 24, the adjusting rod 22 is limited.

[0030] A limiting groove is provided on the outer side of the adjusting rod 22, and the size of the limiting slider 27 is adapted to the limiting groove. The sliding sleeve 25 is slidably installed on the outer side of the adjusting rod 22 through the limiting slider 27.

[0031] The adjusting rod 22 has internal threads, and the support rod 21 is threadedly connected to the adjusting rod 22. The height of the storage tank 1 can be adjusted by rotating the adjusting rod 22.

[0032] Working principle: During the DMTO reaction process, when the storage tank 1 is supported by the support rod 21, and the height of the storage tank 1 needs to be adjusted, the sliding sleeve 25 is slid upward to separate the retaining rod 26 from the annular plate 24. The adjusting rod 22 is then rotated to adjust the height of the storage tank 1. After adjustment, the sliding sleeve 25 is slid downward to engage the retaining rod 26 with the annular plate 24, thus limiting the adjustment rod 22. The second connecting pipe 4 is then connected to the inlet of the external heat exchanger. The hopper 5 is installed on the top of the storage tank 1. The mounting plate 10 on the outside of the hopper 5 is located at the top of the vertical rod 7. The threaded connecting rod 8 at the top of the vertical rod 7 passes through the mounting plate 10. Then, the threaded cap 9 is connected to the threaded connecting rod. The hopper 5 is fixed by a threaded connection. The hopper 5 is connected to the storage tank 1 through the third connecting pipe 18. The horizontal plate 12 is then installed on the top of the hopper 5 through the limiting protrusion 11 and the buckle plate 13. When the material is poured into the storage tank 1 through the hopper 5, the hopper 5 is pressed back and forth, which causes the unblocking rod 14 to slide. The conical head 17 at the bottom of the unblocking rod 14 will unblock the flow and improve the flow. Then the pressurizing air source 20 is started to spray the solid calcium hydroxide particles inside the storage tank 1 into the heat exchanger through the second connecting pipe 4, thereby impacting the catalyst attached to the heat exchanger tube bundle, causing it to fall off, improving the efficiency of the heat exchanger, and avoiding water system fluctuations and water quality deterioration.
