[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Please refer to Figure 1-4 A waste heat power generation equipment cooling tap water recycling device includes a buffer tank 1, a guide cylinder 2 installed in the middle of the buffer tank 1, a frame fixedly installed in the middle of the guide cylinder 2, a rotating shaft 3 rotatably installed on the frame, an axial flow impeller 4 fixedly installed on the rotating shaft 3, an outlet pipe 5 installed on the upper part of the rotating shaft 3, and a booster pump 6. The outer wall of the outlet pipe 5 is rotatably and sealingly connected to the upper part of the guide cylinder 2. The outlet pipe 5 is provided with multiple water inlets 7 communicating with the inside of the guide cylinder 2. An annular outlet 8 is formed between the upper part of the inner wall of the outlet pipe 5 and the outer wall of the rotating shaft 3. Further, the outer wall of the outlet pipe 5 is rotatably and sealingly connected to the upper part of the guide cylinder 2 by a mechanical shaft seal or packing.

[0024] The frame includes a support column 14 and a spiral guide vane 15. The support column 14 is fixedly connected to the inner wall of the guide cylinder 2 through the spiral guide vane 15. A spiral guide channel is formed between the outer wall of the support column 14, the inner wall of the guide cylinder 2 and the spiral guide vane 15. An auxiliary impeller 16 located above the frame is installed on the rotating shaft 3. Furthermore, the blades on the auxiliary impeller 16 are arranged radially along the rotating shaft 3 and are parallel to the central axis of the rotating shaft 3.

[0025] For details, please refer to Figure 5 The bottom of the buffer box 1 is provided with a drain pipe 21 that communicates with the inside of the buffer box 1, and a drain valve 22 is installed at the drain pipe 21.

[0026] In this embodiment, the input end of the booster pump 6 extends to the bottom of the buffer tank 1, so that the tap water in the buffer tank 1 flows back into the buffer tank 1 after passing through the guide tube 2 and the outlet pipe 5, thus achieving the cooling treatment of the tap water in this cycle; the tap water pumped into the guide tube 2 by the booster pump 6 flows through the spiral guide channel and acts on the auxiliary impeller 16. The swirling flow does work on the auxiliary impeller 16, and the auxiliary impeller 16 drives the rotating shaft 3 to rotate, further converting the water pressure kinetic energy of the tap water into the rotational kinetic energy of the rotating shaft 3, thereby improving the water pressure utilization rate of the tap water; the drain pipe 21 can be connected to the external sewage treatment equipment, and after opening the drain valve 22, the collected and cooled tap water is sent to the subsequent sewage treatment equipment for treatment.

[0027] Please refer to Figure 1 or Figure 5 The upper part of the buffer tank 1 is provided with a sedimentation tank 9, and the middle part of the sedimentation tank 9 is provided with an overflow port 10 that communicates with the inside of the buffer tank 1; furthermore, the guide tube 2 is located in the middle of the overflow port 10.

[0028] Please refer to Figures 1-3 A conical guide plate 11 is provided on the upper part of the outlet pipe 5. A conical baffle 12 located on the upper part of the conical guide plate 11 is fixedly installed on the rotating shaft 3. Multiple heat dissipation blades 13 with evenly distributed axes are fixedly installed on the top of the rotating shaft 3.

[0029] For details, please refer to Figure 5 It also includes a flushing pipe 17 and a drain pipe 18 that communicates with the interior of the sedimentation tank 9. The input end of the flushing pipe 17 is connected to the output end of the booster pump 6, and the output end of the flushing pipe 17 extends into the sedimentation tank 9. A shut-off valve 19 is installed on the flushing pipe 17, and a drain valve 20 is installed on the drain pipe 18.

[0030] The waste heat power generation equipment cooling tap water recycling device also includes a buffer tank 23. An inlet pipe 24 is installed on the upper part of the buffer tank 23, and the input end of the booster pump 6 extends into the bottom of the buffer tank 23. The buffer tank 23 can initially buffer the relatively small flow of tap water used for cooling the power generation equipment to ensure that the booster pump 6 has sufficient water for extraction. The tap water discharged from the upper part of the outlet pipe 5 flows onto the conical guide plate 11. Under the action of the conical guide plate 11, the tap water is further dispersed, while the conical baffle 12 prevents the water from flowing further upwards, causing the tap water to spray out in a conical water curtain shape, further improving the dispersion effect of the tap water and increasing the heat dissipation area. During the rotation of the rotating shaft 3, the cooling blades 13 rotate, accelerating the surrounding airflow. The flow of water accelerates the heat dissipation of tap water, further improving the cooling effect. After cooling, the tap water falls into the sedimentation tank 9, where it settles freely. Particles in the tap water fall to the bottom of the sedimentation tank 9, while the clean upper layer of liquid flows into the buffer tank 1 through the overflow port 10 to remove particles from the tap water. When the amount of particles in the sedimentation tank 9 is too large, the shut-off valve 19 is opened, and the booster pump 6 injects some tap water into the sedimentation tank 9. At the same time, the drain valve 20 is opened, and the sediment in the sedimentation tank 9 is flushed out through the drain pipe 18, achieving self-cleaning treatment of the sedimentation tank 9.

[0031] The operation process of the waste heat power generation equipment cooling tap water recycling device provided by this utility model is as follows: Cooling tap water for the preheating power generation equipment is injected into the buffer tank 23 through the inlet pipe 24. After the tap water reaches a certain amount, the pressurizing pump 6 is started. The pressurizing pump 6 pressurizes the cooled tap water and injects it into the guide tube 2. The pressurized tap water contacts the axial flow impeller 4 and the auxiliary impeller 16, driving the axial flow impeller 4 to rotate. The rotating shaft 3 drives the outlet pipe 5 to rotate. The tap water enters the outlet pipe 5 through the inlet 7 and flows out through the annular outlet 8, passing through the conical guide plate 11 and the conical baffle. Under the rotation of the flow cover 12 and the outlet pipe 5, the centrifugal force generated by the rotation will evenly throw the tap water out in all directions. The tap water after being thrown out forms a cone-shaped liquid surface. The rotating shaft 3 drives the heat dissipation blades 13 to rotate and accelerate the surrounding air flow. The cone-shaped liquid surface can fully contact the flowing air and dissipate heat, thus cooling the tap water. After cooling, the tap water falls into the sedimentation tank 9 and settles. Then, it flows back to the buffer tank 1 through the overflow port 10. The buffer tank 1 can collect the cooled tap water. When the tap water in the buffer tank 1 reaches a certain amount, it can be sent to the sewage treatment workshop for treatment and reuse.
