Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between 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.

[0043] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Example, refer to Figures 1-5 As an embodiment of this utility model, a combined drainage cooling system is proposed, including a water storage tank 1, a heat exchanger 2, a cooling box 3, a first control valve 4, a second control valve 5, and a third control valve 6. The water storage tank 1 has a hot drainage outlet 7; the heat exchanger 2 has a hot water inlet 8 and a hot water outlet 9; the cooling box 3 has a water inlet 10 to be cooled; one end of the first control valve 4 is connected to the hot drainage outlet 7, and the other end of the first control valve 4 is connected to the hot water inlet 8; one end of the second control valve 5 is connected to the hot drainage outlet 7, and the other end of the second control valve 5 is connected to the water inlet 10 to be cooled; one end of the third control valve 6 is connected to the hot water outlet 9, and the other end of the third control valve 6 is connected to the water inlet 10 to be cooled.

[0045] In this embodiment, the top of the water storage tank 1 has a hot drainage inlet 33, which is connected to the hot drainage system via a booster pump. The normal hot drainage temperature is 60~100℃. When heat exchange is required, the first control valve 4 and the third control valve 6 are opened, and the second control valve 5 is closed. The hot drainage flows out from the hot drainage outlet 7 of the water storage tank 1, enters the hot water inlet 8 of the heat exchanger 2 through the first control valve 4, and exchanges heat with the cold water in the heat exchanger 2. The cold water is heated to 40~60℃ and flows out from the cold water outlet of the heat exchanger 2, which can be supplied to the workshop as air conditioning hot water and process hot water. The cooled hot drainage flows out from the hot water outlet 9 of the heat exchanger 2, enters the cooling box 3 through the third control valve 6 for further cooling, and is discharged after the temperature drops below 40℃. When there is no need for heat exchange, the first control valve 4 and the third control valve 6 are closed, and the second control valve 5 is opened. The hot drainage flows out from the hot drainage outlet 7 of the water storage tank 1, enters the cooling box 3 directly through the second control valve 5, and is discharged after the temperature drops below 40℃. This equipment can both recover and utilize the heat from hot wastewater to generate hot water at 40-60°C for workshop use, improving energy efficiency, and has a cooling function. When there is no need for heat exchange, it can reduce the temperature of hot wastewater to below 40°C before discharge, meeting emission regulations, achieving two goals at once.

[0046] The water storage tank 1, heat exchanger 2, and cooling box 3 can be combined into one unit or installed as three separate units. The three parts complement each other and operate independently, with different operating modes selected according to different working conditions. The system can be installed underground or above ground, and the installation method can be chosen according to the discharge form of the on-site thermal drainage system (pressure flow or gravity flow), avoiding local limitations imposed by the site.

[0047] For common medical projects (in Northeast China or other areas with permafrost depth greater than 1.0m), the thermal drainage system takes into account the local permafrost depth and the dimensions of the single-story ground beam structure. The installation height of the outlet pipe is mostly -1.0 to -1.5m. The water storage tank and the booster pump can be installed underground in a fiberglass enclosure, with external brick or concrete structure protection, occupying an area of ​​about 4m². 2 Within this system, the approach is similar to that used in small swimming pools and other integrated water treatment systems on the market; for pressurized flow hot drainage systems, the water storage tank 1 and the booster pump can be installed on the ground, sharing a single housing structure with other components.

[0048] The hot wastewater from individual workshops in pharmaceutical plants can be either continuous flow (mainly from air conditioning units and pure water units) or discontinuous flow (mostly from equipment such as sterilizers). The water volume is relatively small. The effective volume of storage tank 1 can be calculated based on a flow rate of 5-10 minutes. The water pump should be selected based on the peak drainage volume, ensuring no more than 6 starts per hour. Specific selection requires consideration of the drainage volume and work schedule provided by the process. Storage tank 1 and the booster pump serve as the power station, primarily ensuring that the hot wastewater in the subsequent heat exchanger 2 and cooling box 3 can exchange heat at a suitable flow rate or mix with clean wastewater.

[0049] Traditional cooling tanks are large, difficult to locate, and have long construction cycles (curing time for concrete structures and construction time for large-volume block structures), and are prone to leakage. The water storage tank 1 and booster pump in this application are small in size, requiring less floor space when buried underground. The heat exchanger 2 and cooling box 3 can be installed above ground, significantly reducing construction time, cost, and difficulty, especially for renovation projects. Combining all components into a single unit reduces underground construction work, offering advantages such as high equipment centralization, convenient installation, short construction period, easy monitoring, and safe operation. This system is suitable for new and expanded pharmaceutical production workshops, especially those with strict site requirements and where initial heat drainage or heat recovery solutions are inadequate, requiring additional space later. The high degree of equipment integration facilitates on-site installation and construction, eliminating the need for excavating traditional cooling tanks underground, thus reducing construction costs.

[0050] Furthermore, the cooling box 3 has a cold water inlet 11 and a drain outlet 12, and also includes a first flow guide baffle 13 and a steam pipe 14. The first flow guide baffle 13 is disposed inside the cooling box 3, dividing the interior of the cooling box 3 into a first chamber 15 and a second chamber 16. The cooling water inlet 10 is connected to the first chamber 15, and both the cold water inlet 11 and the drain outlet 12 are connected to the second chamber 16. The lower end of the first flow guide baffle 13 has a first water passage hole 17 that penetrates its thickness, and the cooling water inlet 10 is located above the first water passage hole 17. The steam pipe 14 is disposed above the cooling box 3, and the lower end of the steam pipe 14 is connected to the first chamber 15.

[0051] When the cooling chamber 3 is used for the first time, cold water needs to be injected to the maximum level through the cold water inlet 11 to facilitate the immediate mixing of the hot water drainage with the existing cold water for rapid cooling. The cooling chamber 3 is internally equipped with a first guide baffle 13 with a first water passage 17, dividing the interior into two chambers. The hot water drainage enters the first chamber 15 through the cooling water inlet 10 and mixes with the existing cold water in the first chamber 15. The steam discharged through the steam pipe 14 carries away some of the heat from the water, thus initially cooling the hot water drainage entering the cooling chamber 3. Then, it enters the second chamber 16 through the first water passage 17 on the lower side, mixing with the cold water in the second chamber 16 for further cooling. When the temperature in the second chamber 16 is high, cold water can be added to the second chamber 16 through the cold water inlet 11 to ensure that the temperature drops below 40°C before being discharged.

[0052] Furthermore, such as Figure 5 As shown, it also includes a cold water supply pipe 18, which is disposed in the second chamber 16 and connected to the cold water inlet 11. The length direction of the cold water supply pipe 18 is the same as the length direction of the first guide baffle 13. The side wall of the cold water supply pipe 18 has multiple spray holes 19, all of which are arranged along the length direction of the cold water supply pipe 18. Taking the example that the length directions of the first guide baffle 13 and the cold water supply pipe 18 are both arranged in the front-back direction, all the spray holes 19 are arranged in the front-back direction. When the temperature in the second chamber 16 is high, cold water can be supplied to the second chamber 16 through the cold water inlet 11 and the cold water supply pipe 18. The cold water is evenly sprayed into the second chamber 16 through the spray holes 19 on the cold water supply pipe 18, and is fully mixed with the hot water drainage, which can improve the cooling efficiency.

[0053] Furthermore, it also includes a control module 20, a cold water supply valve 22, and first control valves 4, 5, and 6, all of which are electrically connected to the control module 20; a first temperature sensor 21, which is used to detect the temperature inside the second chamber 16, and the output of the first temperature sensor 21 is electrically connected to the control module 20; the outlet of the cold water supply valve 22 is connected to the cold water inlet 11, and the cold water supply valve 22 is electrically connected to the control module 20. Connect the inlet of the cold water supply valve 22 to the cold water delivery equipment. After the hot water is initially cooled, it enters the second chamber 16 through the first water passage 17 on the lower side, mixes with the cold water in the second chamber 16, and cools down again. The first temperature sensor 21 can detect the temperature in the second chamber 16 in real time. When the temperature in the second chamber 16 reaches the set upper limit (e.g., 40°C), the first temperature sensor 21 transmits a signal to the control module 20 to open the cold water supply valve 22 and start supplying water. When the temperature in the second chamber 16 drops to the set lower limit (e.g., 39°C), the first temperature sensor 21 transmits a signal to the control module 20 to close the cold water supply valve 22. This automated control saves time and effort.

[0054] Furthermore, the system includes a drain pump 23 and a second temperature sensor 24. The inlet of the drain pump 23 is connected to the drain outlet 12, and the drain pump 23 is electrically connected to the control module 20. The second temperature sensor 24 is located between the drain pump 23 and the drain outlet 12, and its output is electrically connected to the control module 20. The control module 20 is also electrically connected to the drain pump 23. The drain pump 23 can promptly discharge the cooled water from the cooling tank 3, ensuring the drainage efficiency of the entire system and preventing water accumulation from affecting the normal operation of the system. The second temperature sensor 24 can re-detect the drainage temperature to ensure it meets the discharge requirements. If the temperature is abnormal, it can promptly report back to the control module 20 to shut down the drain pump 23.

[0055] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, it also includes a second flow guide baffle 25 and a third flow guide baffle 26. The second flow guide baffle 25 is disposed inside the cooling box 3 and is located between the first flow guide baffle 13 and the drain outlet 12. The lower end of the second flow guide baffle 25 has a second water passage hole 27 that penetrates its thickness. The upper end face of the second flow guide baffle 25 is located above the first water passage hole 17. The drain outlet 12 is located between the upper end face of the second flow guide baffle 25 and the second water passage hole 27. The third flow guide baffle 26 is disposed inside the cooling box 3 and is located between the first flow guide baffle 13 and the second flow guide baffle 25. The lower end face of the third flow guide baffle 26 is sealed to the cooling box 3. The upper end face of the third flow guide baffle 26 is located below the upper end face of the second flow guide baffle 25 and above the first water passage hole 17 and the second water passage hole 27.

[0056] Taking the first flow guide baffle 13, the third flow guide baffle 26, and the second flow guide baffle 25 arranged from right to left in the cooling box 3 as an example, after the hot water is initially cooled in the first chamber 15, it enters between the first flow guide baffle 13 and the third flow guide baffle 26 through the first water passage 17 at the lower end of the first flow guide baffle 13, and exchanges heat with the existing cold water. When the temperature in the second chamber 16 reaches the set upper limit (e.g., 40°C), the first temperature sensor 21 transmits a signal to the control module 20, opens the cold water supply valve 22, and starts to supply water. When the temperature in the second chamber 16 drops to the set lower limit (e.g., 39°C), the first temperature sensor 21 transmits a signal to the control module 20, closes the cold water supply valve 22, and stops supplying water. After cooling, the water between the first guide baffle 13 and the third guide baffle 26 overflows between the second guide baffle 25 and the third guide baffle 26, mixes with existing cold water for further cooling, and then flows through the second water passage 27 to the area between the second guide baffle 25 and the drain outlet 12, where it mixes with existing cold water again for further cooling before being discharged through the drain outlet 12. This repeated mixing with cold water ensures that the hot wastewater is cooled to below 40°C. The control panel of the cold water conveying equipment has automatic control buttons, manual control buttons, and can also display the drainage temperature and the on / off status of each control valve.

[0057] Furthermore, the system includes a circulation pump 28, and both the first control valve 4 and the second control valve 5 are connected to the hot wastewater outlet 7 via the circulation pump 28. The circulation pump 28 provides power to ensure that the hot wastewater can smoothly pass through the first control valve 4 into the heat exchanger 2, or through the second control valve 5 into the cooling box 3, thereby improving the reliability and stability of the system.

[0058] Furthermore, it also includes a pressure gauge 29 and a thermometer 30. The pressure gauge 29 is installed on the water storage tank 1; the thermometer 30 is installed on the water storage tank 1. The pressure gauge 29 can monitor the pressure inside the water storage tank 1 in real time, and the thermometer 30 can monitor the temperature of the hot water drain inside the water storage tank 1 in real time, providing a reference for the control and operation of the system.

[0059] Furthermore, it also includes a safety valve 31, which is installed on the water storage tank 1. When the pressure inside the water storage tank 1 exceeds the safety value, the safety valve 31 will automatically open to release the pressure, preventing danger and ensuring the safe operation of the system.

[0060] Furthermore, it also includes an insulation cover 32, which is installed on the outer wall of the water storage tank 1. This can reduce the heat loss from the hot water drainage inside the water storage tank 1, improve energy utilization, and at the same time prevent condensation on the outer wall of the water storage tank 1, thus protecting the equipment and the surrounding environment.

[0061] 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.
