Description

Technical Field

[0001] The invention belongs to the technical field of cooling towers, and in particular relates to a cooling tower water replenishment system and cooling tower equipment. Background Art

[0002] The cooling tower's water makeup system automatically or manually replenishes water lost through evaporation, drift, or blowdown, maintaining the water level balance of the cooling tower's circulating water system. This makeup water must meet water quality requirements (such as hardness, pH, and turbidity) and typically undergoes filtration or softening. The core component is the automatic makeup valve: this valve automatically starts and stops based on the water level sensor signal, typically implemented using a float valve or solenoid valve. The control logic utilizes water-level linkage control, initiating makeup when the water level falls below the set point. The system also works in conjunction with the blowdown system to achieve dynamic balance. PVC or PP fillers are used inside the cooling tower to increase the water-air contact area and enhance evaporative cooling efficiency.

[0003] Cooling tower water supply systems generally use an automatic water supply valve combined with a water level sensor control mode. The core components are mostly float valves or solenoid valves. The operating logic of this type of system relies on electronic signal transmission and actuator drive. It not only requires continuous consumption of external energy such as electricity, which directly increases the operating cost and usage burden of the equipment, but also has multiple potential defects. This type of system requires complex circuit wiring and control system matching, is difficult to install and maintain, and requires professional personnel to handle subsequent maintenance, further increasing the management cost of the equipment and presenting defects. Summary of the Invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a cooling tower water replenishment system and cooling tower equipment, which have the advantages of achieving efficient cooling and stable water replenishment, and have significantly improved energy saving and reliability compared with the existing technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a cooling tower water supply system, comprising: a water supply pipe, the cooling tower water supply system also comprising: A water tank is arranged below the water supply pipe; The pressure control assembly is arranged inside the water tank and includes: a sealing block, a connecting ring is provided on the outer surface of the sealing block, and a connecting hole is opened on the lower surface of the connecting ring; The flow control assembly is arranged on one side of the water supply pipe and includes: a baffle; The sealing block moves up and down inside the connecting hole to control the on and off of the water supply pipe. At the same time, the baffle moves up and down to adjust the cross-sectional area through which the water supply pipe can pass.

[0006] As a preferred embodiment of the cooling tower water replenishment system of the present invention, the pressure control component further comprises: The mounting pipe is arranged inside the water tank and below the sealing block; the adjusting block is embedded in the mounting pipe; The push rod is fixedly connected to the upper surface of the adjusting block, and the upper end thereof is fixedly connected to the lower surface of the sealing block.

[0007] By adopting this technical solution, the mounting tube provides stable installation and movement space for the regulating block and push rod, allowing the regulating block to move steadily up and down within the mounting tube. When the water level in the water tank fluctuates, the water pressure on the regulating block changes. The regulating block drives the sealing block to move synchronously via the push rod, thereby precisely controlling the sealing block's connection to the water supply pipe. This achieves automatic control based on water level pressure, improving the automation level and responsiveness of the water supply system.

[0008] As a preferred embodiment of the cooling tower water replenishment system of the present invention, the pressure control component further comprises: The cover plate is fixed to the upper end of the mounting tube, and a mounting hole is formed on the upper surface of the cover plate; The first sealing ring is embedded in the inner wall surface of the mounting hole, and the inner wall surface is sleeved on the outer surface of the push rod; The mounting groove is provided on the outer surface of the adjusting block; The outer surface of the second sealing ring is embedded in the interior of the installation groove, and the outer surface is in contact with the inner wall surface of the installation pipe.

[0009] By adopting this technical solution, the cover plate seals the upper end of the mounting tube, preventing impurities from entering the tube and affecting the proper operation of the adjustment block and push rod. The first seal ring effectively seals the push rod and the mounting hole, preventing water from the water tank from seeping into the mounting tube through the hole. The second seal ring strengthens the seal between the adjustment block and the inner wall of the mounting tube, preventing water from flowing through the gap between the adjustment block and the mounting tube and affecting the accuracy of pressure control. This significantly improves the sealing performance and operational reliability of the pressure control assembly.

[0010] As a preferred embodiment of the cooling tower water replenishment system of the present invention, the pressure control component further comprises: Two support blocks are provided, one surface of which is fixedly connected to the lower end of the mounting tube; Wherein, the two support blocks are distributed equidistantly around the circumference.

[0011] By adopting the above technical solution, two equidistantly distributed support blocks raise the installation pipe to ensure that the interior of the installation pipe is connected with the outside world.

[0012] As a preferred embodiment of the cooling tower water replenishment system of the present invention, the pressure control component further comprises: The sight glass is embedded in the outer surface of the mounting tube.

[0013] By adopting this technical solution, workers can directly observe the position and movement of the regulating block inside the mounting tube through the viewing glass, facilitating real-time monitoring of the pressure control assembly's operation. In the event of a system failure, they can quickly determine whether the regulating block is functioning properly, shortening troubleshooting time, reducing maintenance effort, and improving system maintainability.

[0014] As a preferred embodiment of the cooling tower water supply system of the present invention, the flow control component further includes: A baffle is embedded in the outer surface of the water supply pipe, and one end of the baffle passes through the inner wall of the water supply pipe; The third sealing ring is sleeved on the outer surface of the baffle, and the outer surface is embedded in the interior of the water supply pipe; A connecting rod, fixed to the lower end of the baffle; A float ball is fixed to the lower end of the connecting rod; When the water level fluctuates, the float drives the baffle to move up and down inside the water supply pipe through the connecting rod.

[0015] By adopting this technical solution, the float rises and falls with the water level in the tank, driving the baffle to move synchronously via the connecting rod, enabling real-time adjustment of the cross-sectional area of ​​the water supply pipe. When the water level is low, the baffle moves upward, increasing the flow area of ​​the water supply pipe and accelerating the water supply. When the water level is high, the baffle moves downward, reducing the flow area and slowing the water supply. This effectively achieves automatic adjustment of the water supply flow rate, preventing over- or under-supply. Furthermore, a third sealing ring ensures a seal between the baffle and the water supply pipe, preventing water from leaking through the gap and ensuring precise flow regulation.

[0016] The cooling tower equipment includes the above-mentioned cooling tower water replenishment system and also includes: a shell, a heat exchanger is fixedly connected to the interior of the shell, and a spraying device is arranged above the heat exchanger.

[0017] As a preferred embodiment of the cooling tower equipment of the present invention, two air inlet grilles are embedded in the outer surface of the shell, and a heat dissipation fan is connected to the upper surface of the shell.

[0018] By employing this technical solution, the air intake grille draws cool air from the outside into the enclosure, while the cooling fan accelerates the exhaust of hot air from the enclosure, creating a well-functioning air circulation system. This cool air exchanges heat with the heat exchanger and spray system inside the enclosure, removing heat and significantly improving the cooling tower's heat dissipation efficiency. This ensures that the equipment can quickly and effectively reduce the temperature of the circulating water to meet cooling requirements.

[0019] As a preferred embodiment of the cooling tower equipment of the present invention, the inner wall surface of the shell is sleeved on the outer surface of the water tank.

[0020] By adopting this technical solution, the housing effectively protects the water tank, reducing the impact of external environmental factors (such as dust, rain, and collisions) on the water tank, and extending the tank's service life. Furthermore, this sleeve structure makes the water tank and housing an organic whole, saving installation space and improving the compactness of the device.

[0021] As a preferred embodiment of the cooling tower equipment of the present invention, a back plate is fixedly connected to the rear surface of the shell.

[0022] By adopting this technical solution, the backplate seals the rear of the cooling tower, preventing foreign matter from entering the enclosure and protecting internal components such as the heat exchanger and sprinkler system from damage. Furthermore, the backplate strengthens the overall structural strength of the enclosure, making it more stable during operation and improving the overall stability and safety of the equipment.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, during use, the enclosed space formed by the mounting pipe, regulating block, and cover plate is filled with air. When the water level in the water tank drops, water flows out of the mounting pipe, creating negative pressure. This drives the regulating block and sealing ring 2 downward, and the push rod slides downward, disengaging the sealing block from the connecting hole and allowing water to flow through the water supply pipe. When the water level rises, the water pressure pushes the regulating block and sealing ring 2 upward, gradually pushing the sealing block toward the connecting hole. When the water level reaches the designated position, the sealing block blocks the connecting hole, and the water supply pipe stops filling. The compressibility of air provides a flexible buffer for the regulating block, preventing it from getting stuck. Water is automatically replenished based on the pressure difference in the mounting pipe, without the need for external operation.

[0024] 2. In the present invention, during use, the float floats on the water surface, using its buoyancy to support the connecting rod. As the water level drops, the float drops synchronously, driving the connecting rod to move the baffle within the water supply pipe, increasing the flow area and improving water flow to ensure water supply. As the water level rises, the float's buoyancy pushes the baffle upward via the connecting rod, gradually reducing the flow area of ​​the water supply pipe. This linearly adjusts the flow rate in the water supply pipe for precise control. Through the coordinated operation of these three factors, the flow rate in the water supply pipe can be adaptively adjusted, preventing excessive water overflow while ensuring sufficient water flow, thereby improving the user experience.

[0025] 3. In the present invention, the outer shell serves as an external protective structure, supporting and enclosing the internal system, ensuring that the components are stable and protected from external influences. The heat exchanger inside it can exchange heat between hot water and air to reduce the temperature; the spray equipment above evenly sprays water on the surface of the heat exchanger, increasing the contact area to accelerate heat exchange and improve cooling efficiency. The two air intake grilles outside the outer shell control the uniform inflow of air, effectively exchanging heat with hot water; the heat dissipation fan on the upper surface accelerates air flow and enhances the contact effect. The water tank is embedded in the inner wall of the outer shell to store circulating cooling water to ensure continuous cooling. The back panel is fixed to the rear surface of the outer shell to enhance structural stability, prevent air leakage, and ensure the effective operation of the system.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1 like Figure 1-8 As shown: The cooling tower water supply system includes a water supply pipe 1 and further includes: The water tank 8 is arranged below the water supply pipe 1; The pressure control assembly is arranged inside the water tank 8 and includes: a sealing block 19, a connecting ring 9 is provided on the outer surface of the sealing block 19, and a connecting hole 23 is opened on the lower surface of the connecting ring 9; The flow control assembly is provided on one side of the water supply pipe 1 and includes: a baffle 18; The sealing block 19 moves up and down inside the connecting hole 23 to control the on and off of the water supply pipe 1 . At the same time, the baffle 18 moves up and down to adjust the cross-sectional area through which the water supply pipe 1 can pass.

[0029] Further, In an optional embodiment, the pressure control assembly includes: a connecting ring 9, a push rod 10, a cover plate 11, a mounting tube 12, a support block 15, a sight glass 16, a sealing block 19, a sealing ring 1 20, an adjusting block 21, a sealing ring 2 22, a connecting hole 23 and a mounting groove 24.

[0030] Among them, the connecting ring 9 that plays a cooperating role is fixed to the lower end of the water supply pipe 1 through a hexagonal bolt.

[0031] The push rod 10 having a transmission function is fixed to the upper surface of the adjustment block 21 by means of bolts.

[0032] The cover plate 11 serving as a support is fixed to the upper end of the mounting tube 12 by means of bolts and is sleeved on the outer surface of the push rod 10 .

[0033] The mounting tube 12 for stabilizing the pressure is welded to the upper end of the supporting block 15 .

[0034] The supporting block 15 is fixed to the inner wall surface of the water tank 8 by bolts.

[0035] A sealing block 19 for sealing is fixed to the upper end of the push rod 10 by means of bolts.

[0036] A visual glass 16 for observation is embedded in the outer surface of the mounting tube 12 so that the interior of the mounting tube 12 is visible.

[0037] Among them, a sealing ring 20 that plays a sealing role is sleeved on the outer surface of the push rod 10 and embedded in the installation hole of the cover plate 11.

[0038] The adjusting block 21 for adjusting is fixed to the lower end of the push rod 10 by means of bolts and is embedded in the interior of the mounting tube 12 .

[0039] The mounting groove 24 for supporting is cut on the outer surface of the adjusting block 21 by laser. When the water level in the water tank 8 reaches the designated position, the sealing block 19 is completely embedded in the connecting hole 23, blocking the connecting hole 23 and stopping the water supply pipe 1 from filling water. It provides flexible buffering. When the water level in the water tank 8 rises, the water level in the installation pipe 12 rises synchronously, squeezing the air in the enclosed space to increase its pressure and push the regulating block 21 to slide upward. Since the air compression process is progressive, the thrust exerted on the regulating block 21 will increase linearly with the rise in water level, avoiding jamming caused by rigid collision. The water supply pipe 1 can be controlled to open or close according to the pressure difference inside the installation pipe 12. No external operation is required, and the water tank 8 is automatically replenished with water.

[0040] Example 2 On the basis of Example 1, Figure 1-8 As shown: The cooling tower water supply system also includes: a flow control component.

[0041] The flow control components also include: The baffle 18 is embedded in the outer surface of the water supply pipe 1, and one end thereof penetrates the inner wall of the water supply pipe 1; The sealing ring 17 is sleeved on the outer surface of the baffle 18, and the outer surface is embedded in the water supply pipe 1; Connecting rod 13, fixed to the lower end of baffle 18; The float ball 14 is fixed to the lower end of the connecting rod 13; When the water level fluctuates, the float 14 drives the baffle 18 to move up and down inside the water supply pipe 1 through the connecting rod 13 .

[0042] In an optional embodiment, the flow control assembly includes: a connecting rod 13 , a float 14 , a sealing ring 17 , and a baffle 18 .

[0043] The connecting rod 13 serving as a transmission is welded to the lower end of the baffle 18 .

[0044] The floating ball 14 providing kinetic energy is fixed to the lower surface of the connecting rod 13 by bolts.

[0045] Among them, the sealing ring 17 that plays a sealing role is sleeved on the outer surface of the baffle 18 and embedded in the interior of the water supply pipe 1.

[0046] The baffle 18 for adjusting the flow area penetrates the inner wall surface of the water supply pipe 1 .

[0047] It should be noted that the baffle 18 is only used to adjust the flow area of ​​the water supply pipe 1, so its shape includes but is not limited to polygonal, rectangular, and circular. The oblong shape is selected in this application.

[0048] In this embodiment, when in use, the float 14 is on the water surface, supporting the connecting rod 13 with the help of buoyancy. When the water level drops, the float 14 will drop synchronously, driving the connecting rod 13, and then pushing the baffle 18 to move inside the water supply pipe 1. During this process, the movement of the baffle 18 increases the flow area of ​​the water supply pipe 1, thereby improving the flux of water flow in the water supply pipe and ensuring sufficient water supply. When the water level rises, the float 14 again uses buoyancy to push the baffle 18 upward through the connecting rod 13, gradually reducing the flow area of ​​the water supply pipe 1. In this way, the water flow in the water supply pipe 1 is linearly adjusted, thereby achieving precise control of the water flow. The water level change is achieved through the coordinated action of the float 14, connecting rod 13 and baffle 18, so that the flow of the water supply pipe 1 can be adaptively adjusted, which not only avoids overflow caused by excessive water flow, but also ensures sufficient water flow and improves the user experience.

[0049] Example 3 On the basis of Example 2, Figure 1 、 2 、7 as shown: The cooling tower equipment includes a cooling tower water replenishment system, and also includes: an outer shell 2, a heat exchanger 3 is fixedly connected to the interior of the outer shell 2, a spray device 7 is arranged above the heat exchanger 3, two air intake grilles 6 are embedded in the outer surface of the outer shell 2, a heat dissipation fan 4 is connected to the upper surface of the outer shell 2, the inner wall surface of the outer shell 2 is sleeved on the outer surface of the water tank 8, and the rear surface of the outer shell 2 is fixedly connected to the back plate 5.

[0050] In this embodiment, the housing 2 serves as the external protective structure of the equipment, supporting and enclosing the internal system, ensuring that all components are firmly connected and protected from external environmental influences. A heat exchanger 3 is fixedly connected to the interior of the housing 2. Its function is to exchange heat between hot water and external air, thereby reducing the water temperature. A spray device 7 is arranged above the heat exchanger 3 and is responsible for spraying water evenly on the surface of the heat exchanger 3, increasing the contact area between water and air, thereby accelerating heat transfer and exchange and improving cooling efficiency. Two air intake grilles 6 embedded in the outer surface of the equipment's housing 2 control the entry of external air, ensuring that air can flow evenly into the cooling tower and efficiently exchange heat with the hot water. The heat dissipation fan 4 is located on the upper surface of the housing 2 and is responsible for guiding and accelerating air flow, enhancing the contact effect between air and hot water, and improving cooling efficiency. A water tank 8 is embedded in the inner wall surface of the housing 2 to store and circulate cooled water, providing a stable water supply and ensuring the continuity of the cooling process. The back plate 5 is fixedly connected to the rear surface of the housing 2 by bolts, providing additional support, enhancing the overall structural stability of the equipment, and preventing external air leakage to ensure the effective operation of the cooling system.

[0051] The implementation principles of the cooling tower water replenishment system and cooling tower equipment of the present invention are as follows: When in use, air is filled into the enclosed space formed by the mounting pipe 12, the regulating block 21 and the cover plate 11, and the water level inside the water tank 8 drops. Under the action of water pressure, the water inside the mounting pipe 12 flows out, forming a negative pressure, so that the regulating block 21 drives the sealing ring 22 to slide downward inside the mounting pipe 12 through the mounting groove 24 under the action of negative pressure, and the push rod 10 slides down inside the sealing ring 1 20, controlling the sealing block 19 to disengage from the connecting hole 23, opening one end of the water supply pipe 1, and water flows into the water tank 8 through the connecting hole 23. The water level inside the water tank 8 continues to rise, and the water pressure on the sealing ring 22 and the regulating block 21 continues to increase. The sealing ring 22 and the regulating block 21 continue to slide up inside the mounting pipe 12, causing the sealing block 19 to continue to approach the connecting hole 23. Until the water level reaches the specified position of the water tank 8, the sealing block 19 is completely embedded in the connecting hole 23, blocking the connecting hole 23, and stopping the water supply pipe 1 from filling with water. The compressibility of air is the regulating block 21 Provide flexible buffering. When the water level in the water tank 8 rises, the water level in the installation pipe 12 rises synchronously, squeezing the air in the enclosed space to increase its pressure and push the regulating block 21 to slide upward. Since the air compression process is progressive, the thrust exerted on the regulating block 21 will increase linearly with the rise in water level, avoiding jamming caused by rigid collision.

[0052] During use, the float 14 is on the water surface, supporting the connecting rod 13 with the help of buoyancy. When the water level drops, the float 14 will drop synchronously, driving the connecting rod 13, and then pushing the baffle 18 to move inside the water supply pipe 1. During this process, the movement of the baffle 18 increases the flow area of ​​the water supply pipe 1, thereby increasing the flux of water flow in the water supply pipe and ensuring sufficient water supply. When the water level rises, the float 14 again uses buoyancy to push the baffle 18 upward through the connecting rod 13, gradually reducing the flow area of ​​the water supply pipe 1. In this way, the water flow in the water supply pipe 1 is linearly adjusted, thereby achieving precise control of the water flow. The water level change is achieved through the coordinated action of the float 14, connecting rod 13 and baffle 18, so that the flow of the water supply pipe 1 can be adaptively adjusted.

[0053] The outer shell 2 serves as the external protective structure of the equipment, supporting and enclosing the internal system, ensuring that all components are firmly connected and protected from external environmental influences. A heat exchanger 3 is fixedly connected to the inside of the outer shell 2. Its function is to exchange heat between hot water and external air, thereby reducing the water temperature. A spray device 7 is arranged above the heat exchanger 3 and is responsible for spraying water evenly on the surface of the heat exchanger 3, increasing the contact area between water and air, thereby accelerating heat transfer and exchange and improving cooling efficiency. Two air intake grilles 6 embedded in the outer surface of the outer shell 2 of the equipment control the entry of external air, ensuring that air can flow evenly into the cooling tower and efficiently exchange heat with hot water. The heat dissipation fan 4 is located on the upper surface of the outer shell 2 and is responsible for guiding and accelerating air flow, enhancing the contact effect between air and hot water, and improving cooling efficiency. The water tank 8 is embedded in the inner wall surface of the outer shell 2 to store and circulate cooled water, provide a stable water supply, and ensure the continuity of the cooling process. The back plate 5 is fixed to the rear surface of the outer shell 2 by bolts, providing additional support, enhancing the overall structural stability of the equipment, and preventing external air leakage to ensure the effective operation of the cooling system.
