Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically to a closed-loop cooling tower. Background Technology

[0002] Closed-circuit cooling towers, as key supporting heat dissipation devices for industrial production, refrigeration systems, and various temperature-controlled equipment, are widely used in chemical, power, and manufacturing industries. Their core function is to remove excess heat generated by target equipment or systems through heat exchange, ensuring that the equipment remains within a suitable operating temperature range, thereby guaranteeing the continuity and stability of the overall production process or system operation. As industrial demands for equipment operating efficiency, adaptability to various operating conditions, and long-term reliability continue to increase, closed-circuit cooling towers must continuously achieve efficient heat transfer under different loads and ambient temperatures to meet the basic cooling requirements of various production scenarios, providing fundamental support for the smooth progress of industrial production.

[0003] In the operation of existing closed-loop cooling towers, the cooling water in the collection tank often lacks effective flow guidance and mixing design, which makes the water prone to being in a relatively static or slow-flowing state. After absorbing heat, the water is difficult to quickly mix with the surrounding low-temperature water due to poor flow, reducing the overall heat transfer efficiency and making it difficult to continuously meet the cooling needs of the equipment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0024] Specific implementation examples are given below.

[0025] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a closed-loop cooling tower, including a water collection tank 1, a cooling chamber 2 fixedly connected to the upper surface of the water collection tank 1, an air outlet 3 fixedly connected to the upper surface of the cooling chamber 2, a fan motor 4 installed on the inner wall of the air outlet 3, a spray water pump 5 fixedly connected to the outer wall of the water collection tank 1, the input end of the spray water pump 5 fixedly connected to the outer wall of the water collection tank 1, a water pipe 6 fixedly connected to the output end of the spray water pump 5, a spray frame 8 fixedly connected to the other end of the water pipe 6, a cooling heat exchange coil 7 installed on the inner wall of the water collection tank 1, a heat exchanger 9 installed on the inner wall of the water collection tank 1, the heat exchanger 9 located below the spray frame 8, a ventilation window 11 installed on the inner wall of the water collection tank 1, a fixing plate 10 fixedly connected to the inner wall of the water collection tank 1, a disturbance mechanism installed on the outer wall of the fixing plate 10, and a self-replenishing water mechanism installed inside the water collection tank 1.

[0026] It should be noted that when the spray water pump 5 on the outer wall of the water collection tank 1 starts working, it draws water from the water collection tank 1 through the input end and then transports the water to the spray frame 8 in the cooling chamber 2 through the water pipe 6 at the output end. The spray frame 8 sprays water onto the heat exchanger 9 below and the cooling heat exchange coil 7 on the inner wall of the water collection tank 1. When the water comes into contact with the heat exchanger 9 and the cooling heat exchange coil 7, it absorbs the heat transferred between them, and its own temperature rises before flowing back to the water collection tank 1, forming a spray water circulation. At the same time, the fan motor 4 on the inner wall of the air outlet 3 starts, driving air to enter the cooling chamber 2 through the ventilation window 11 on the inner wall of the water collection tank 1. The airflow comes into contact with the spray water in the cooling chamber 2, carrying away the heat generated by the evaporation of the water, and then carrying away the heat... Air is exhausted from the air outlet 3 to dissipate heat. During this process, the disturbance mechanism on the outer wall of the fixed plate 10 operates synchronously, causing the filter plate 12 to vibrate to prevent impurities from clogging the filter and ensuring smooth filtration of the return water. On the other hand, it drives the disturbance plate 40 to move horizontally back and forth, stirring the water in the water collection tank 1 to avoid local water temperature from getting too high and to improve the efficiency of subsequent spray cooling. If the water level in the water collection tank 1 drops due to evaporation or other reasons, the internal self-water replenishment mechanism will be automatically activated. The float 17 senses the water level change and links the vibration column 15, piston 25 and other components to open the water replenishment channel, so that the water in the water tank 41 is injected into the water collection tank 1 through the L-shaped pipe 23 and the second water pipe 26 to maintain a stable water level and ensure that the entire cooling process continues to be efficient.

[0027] In an optional embodiment, the disturbance mechanism includes a support plate 27, the outer wall of which is fixedly connected to the outer wall of a fixed plate 10. A second motor 28 is fixedly connected to the upper surface of the support plate 27. The output end of the second motor 28 is rotatably connected to the inside of the fixed plate 10 and fixedly connected to a second rotating rod 34. The outer wall of the second rotating rod 34 is rotatably connected to the inside of the fixed plate 10. The disturbance mechanism also includes a pulley 29, the inside of which is fixedly connected to the outer wall of the second rotating rod 34. A transmission belt 30 is connected to the outer wall of the pulley 29. A second pulley 31 is connected to the inner wall of the transmission belt 30. A first rotating rod 32 is fixedly connected to the inner wall of the second pulley 31. The outer wall of the first rotating rod 32 is rotatably connected to the inside of the fixed plate 10. A torque converter is fixedly connected to the outer wall of the first rotating rod 32. The rectangular block 33; the disturbance mechanism includes a vibrating block 14, the outer wall of which slides intermittently on the outer wall of the rectangular block 33, a filter plate 12 fixedly connected to the upper surface of the vibrating block 14, one end of a spring 13 fixedly connected to the lower surface of the filter plate 12, and the other end of the spring 13 fixedly connected to the inner wall of the water collection tank 1; the disturbance mechanism also includes an inclined disc 35, the interior of which is fixedly connected to the outer wall of the rotating rod 34, both ends of which are slidably connected to a hemisphere 36, the outer wall of which is fixedly connected to a connecting block 37, and the lower surface of the connecting block 37 is fixedly connected to a sliding rod 38; the disturbance mechanism also includes a support frame 39, the upper surface of which is fixedly connected to the lower surface of the sliding rod 38, and the outer wall of which is fixedly connected to a disturbance plate 40.

[0028] It should be noted that when the disturbance mechanism is activated, the second motor 28, fixed on the support plate 27, provides power. The output end of the second motor 28 rotates and drives the second rotating rod 34 to rotate inside the fixed plate 10. The rotation of the second rotating rod 34 will, on the one hand, drive the first pulley 29 fixed on the outer wall to rotate synchronously. The first pulley 29, through the transmission belt 30, causes the second pulley 31 to rotate. The second pulley 31 then drives the first rotating rod 32 fixed on the inner wall to rotate inside the fixed plate 10. After the first rotating rod 32 rotates, the rectangular block 33 on its outer wall will... The vibrating block 14 is pushed intermittently, causing the vibrating block 14 to drive the filter plate 12 to move up and down. The spring 13 extends and retracts accordingly. On the other hand, the rotation of the rotating rod 2 34 will drive the inclined disk 35 fixed on the outer wall to rotate synchronously. When the inclined disk 35 rotates, the inclined surfaces at both ends will intermittently push the hemisphere 36 to slide in the horizontal direction. The hemisphere 36 causes the sliding rod 38 to move horizontally through the connecting block 37. The sliding rod 38 then drives the support frame 39 and the disturbance plate 40 fixed on the outer wall to move horizontally back and forth, thereby realizing the lateral agitation of the water in the water collection tank 1. The up-and-down vibration of the filter plate 12 can effectively prevent impurities in the water from accumulating and clogging its surface, ensuring unobstructed filtration channels, reducing equipment failures caused by filtration failure, and reducing the frequency of manual cleaning. The horizontal reciprocating movement of the disturbance plate 40 can create lateral agitation of the water in the water collection tank 1, breaking the static state of the water, expanding the contact range between the water and the cooling heat exchange coil 7 and heat exchanger 9, avoiding excessively high local water temperatures, improving the uniformity and efficiency of heat exchange, thereby optimizing the overall cooling performance of the cooling tower and ensuring that the equipment operates under stable conditions. Motor 28 simultaneously drives the filter plate 12 to vibrate and the disturbance plate 40 to move horizontally back and forth. No additional motors and components are required to reduce hardware and energy costs. It also simplifies the internal structure of the water collection tank 1 and avoids component interference. At the same time, it ensures that the two actions are synchronized to improve operational stability and reduce failure points. In the future, only one power source and related components need to be maintained to reduce maintenance difficulty and workload.

[0029] In an optional embodiment, the self-watering mechanism includes a vibrating column 15, the outer wall of which is rotatably connected to the inside of the water collection tank 1, and an adjusting rod 16 fixedly connected to the outer wall of the vibrating column 15, the other end of which is fixedly connected to a float 17; the self-watering mechanism also includes a connecting plate 18, the inside of which is fixedly connected to the outer wall of the vibrating column 15, and a sliding column 19 fixedly connected to the inside of the connecting plate 18, the outer wall of which is slidably connected to a rectangular frame 20; the self-watering mechanism also includes a pull rod 21, one end of which is fixedly connected to the outer wall of the rectangular frame 20, and the outer wall of the sliding column 19 is slidably connected to the inner wall of the rectangular frame 20, the pull rod 21 being fixedly connected to the outer wall of the rectangular frame 20, and the outer wall of the sliding column 19 being slidably connected to the inner wall of the rectangular frame 20, the pull rod 21 being fixedly connected to the outer wall of the rectangular frame 20, the pull rod 21 being fixedly connected to the outer wall of the rectangular frame 20, and the pull rod 21 being fixedly connected to the outer wall of the rectangular frame 20, ... The other end of the rod 21 is fixedly connected to a piston 25. The outer wall of the piston 25 is slidably connected to an L-shaped tube 23. The inner wall of the L-shaped tube 23 is fixedly connected to a limiting plate 22. The outer wall of the pull rod 21 is slidably connected to the inside of the limiting plate 22. One end of the piston 25 is fixedly connected to one end of a second spring 24. The other end of the second spring 24 is fixedly connected to one end of the limiting plate 22. The self-water replenishment mechanism also includes a water tank 41. The outer wall of the water tank 41 is fixedly connected to the outer wall of the water collection tank 1. The lower surface of the water tank 41 is fixedly connected to one end of the L-shaped tube 23. The outer wall of the L-shaped tube 23 is fixedly connected to a second water pipe 26. The other end of the second water pipe 26 is fixedly connected to the outer wall of the water collection tank 1.

[0030] It should be noted that when the self-watering mechanism is working, the float 17 first moves up and down with the rise and fall of the water level in the water collection tank 1. This movement causes the vibrating column 15 to rotate around its own axis inside the water collection tank 1 via the adjusting rod 16. After the vibrating column 15 rotates, it drives the connecting plate 18 to rotate synchronously. The connecting plate 18 then causes the sliding column 19 to perform circular motion. As the sliding column 19 slides along the inner wall of the rectangular frame 20, it converts the circular motion into the horizontal linear motion of the rectangular frame 20. The horizontal displacement of the rectangular frame 20 will pull or push... Pull rod 21 slides in a straight line under the limitation of limit plate 22, thereby causing piston 25 to slide on the inner wall of L-shaped tube 23. When the water level is too low, pull rod 21 pulls piston 25 to compress spring 24, opening the water flow channel of L-shaped tube 23. At this time, water in water tank 41 flows into water pipe 26 through L-shaped tube 23, and then into water collection tank 1 through water pipe 26. When the water level rises back to the set value, the elastic force of spring 24 pushes piston 25 to reset, closing the water flow channel of L-shaped tube 23, and the water replenishment action stops. The cooperation between the float 17 and the vibrating column 15 ensures water level changes. The combination of the connecting plate 18, the sliding column 19 and the rectangular frame 20 realizes the smooth conversion of motion mode. The linkage between the pull rod 21, the piston 25 and the second spring 24 ensures the reliability of the opening and closing of the water supply channel. The limit plate 22 avoids failures caused by excessive displacement of components. The water tank 41 provides a stable water supply source. The second water pipe 26 realizes the water supply introduction, achieving the effect of automatic water supply when the water level is lower than the set value and automatic stop when the water level reaches the standard. It effectively maintains the stability of the water level in the water collection tank 1, reduces the problem of cooling tower cooling efficiency reduction or equipment damage caused by abnormal water level, and significantly improves the automation and stability of the closed cooling tower operation.

[0031] Working principle: The spray water pump 5 on the outer wall of the water collection tank 1 starts to work, drawing water from the water collection tank 1 through the input end, and then transporting the water to the spray frame 8 in the cooling chamber 2 through the water pipe 6 at the output end. The spray frame 8 sprays water onto the heat exchanger 9 below and the cooling heat exchange coil 7 on the inner wall of the water collection tank 1. When the water comes into contact with the heat exchanger 9 and the cooling heat exchange coil 7, it absorbs the heat transferred by the two and its own temperature rises before flowing back to the water collection tank 1, forming a spray water circulation. At the same time, the fan motor 4 on the inner wall of the air outlet 3 starts, driving air to enter the cooling chamber 2 through the ventilation window 11 on the inner wall of the water collection tank 1. The airflow comes into contact with the spray water in the cooling chamber 2, carrying away the heat generated by the evaporation of the water. Then the air carrying the heat is discharged from the air outlet 3. When the disturbance mechanism is activated, motor 28, fixed on support plate 27, provides power. The output end of motor 28 rotates, driving rotating rod 34 to rotate inside fixed plate 10. The rotation of rotating rod 34 drives pulley 29, fixed on the outer wall, to rotate synchronously. Pulley 29, through transmission belt 30, causes pulley 31 to rotate. Pulley 31 then drives rotating rod 32, fixed on the inner wall, to rotate inside fixed plate 10. After rotating rod 32 rotates, the rectangular block 33 on its outer wall will intermittently push... Vibrating block 14 causes the filter plate 12 to move up and down, and spring 13 extends and retracts accordingly. On the other hand, rotating rod 2 34 rotates and drives the inclined disk 35 fixed on the outer wall to rotate synchronously. When the inclined disk 35 rotates, the inclined surfaces at both ends will intermittently push the hemisphere 36 to slide in the horizontal direction. The hemisphere 36 causes the sliding rod 38 to move horizontally through the connecting block 37. The sliding rod 38 then drives the support frame 39 and the disturbance plate 40 fixed on the outer wall to move horizontally back and forth, thereby realizing the lateral agitation of the water in the water collection tank 1. When the self-watering mechanism is working, the float 17 first moves up and down with the rise and fall of the water level in the water collection tank 1. This movement causes the vibrating column 15 to rotate around its own axis inside the water collection tank 1 via the adjusting rod 16. After the vibrating column 15 rotates, it drives the connecting plate 18 to rotate synchronously. The connecting plate 18 then causes the sliding column 19 to perform circular motion. As the sliding column 19 slides along the inner wall of the rectangular frame 20, it converts the circular motion into the horizontal linear motion of the rectangular frame 20. The horizontal displacement of the rectangular frame 20 will pull or push the pull rod 2. 1. The pull rod 21 slides in a straight line under the limitation of the limit plate 22, which in turn causes the piston 25 to slide on the inner wall of the L-shaped tube 23. When the water level is too low, the pull rod 21 pulls the piston 25 to compress the second spring 24, opening the water flow channel of the L-shaped tube 23. At this time, the water in the water tank 41 flows into the second water pipe 26 through the L-shaped tube 23, and then into the water collection tank 1 through the second water pipe 26. When the water level rises back to the set value, the elastic force of the second spring 24 pushes the piston 25 to reset, closing the water flow channel of the L-shaped tube 23, and the water replenishment action stops.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
