Description

Technical Field

[0001] This application relates to the field of intelligent control technology for cooling towers, and in particular to an intelligent control system, method, device and medium for cooling towers. Background Technology

[0002] A cooling tower is a liquid cooling device comprising a tower body, air chamber, water collection basin, packing, water distribution device, and fan. The working principle of a cooling tower is as follows: high-temperature liquid is evenly sprayed onto the packing plates inside the air chamber through the water distribution device, forming a water film on the packing plates. The water flows slowly from the top of the packing plates to the water collection basin at the bottom. During the water flow on the packing plates, the fan draws low-temperature air from outside the cooling tower into the cooling tower, blows it onto the packing plates, and then discharges it outside, thus transforming the low-temperature, low-humidity gas into high-temperature, high-humidity gas before it is discharged. According to the principle of energy conservation, the original high-temperature liquid inside the air chamber becomes low-temperature liquid and flows into the water collection basin at the bottom of the tower. The low-temperature liquid is then used by the main unit and other equipment to heat up. The heated cooling liquid is then pumped back into the cooling tower for further cooling, and the cycle repeats continuously.

[0003] Cooling tower equipment requires outdoor fresh air for heat exchange, so it is usually placed in a well-ventilated outdoor location, typically on the rooftop of a building. Therefore, different outdoor temperatures will affect the temperature of the cooling tower's inlet pipe. The maximum load of a cooling tower is designed for the hottest period of the year. If the cooling tower continues to operate at maximum load while the inlet water temperature decreases, it will result in a significant waste of electrical energy. Therefore, it is necessary to adjust the operating parameters of the cooling tower. Currently, this is generally done by personnel detecting a drop in the inlet pipe temperature and then adjusting the operating parameters accordingly. However, this manual adjustment and control method has a certain lag, resulting in poor control of the cooling tower and insufficient energy efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] In order to improve the control effect of cooling towers and achieve energy saving, this application provides an intelligent control system, method, equipment and medium for cooling towers.

[0005] The first objective of this invention is achieved by the following technical solution: An intelligent control system for a cooling tower includes: a cooling tower body, a temperature detection module, a flow detection module, a wind speed measurement module, and a control mechanism; The cooling tower body includes a variable flow water distribution device, an inlet pipe, and an outlet pipe; the variable flow water distribution device is connected to the inlet pipe, both the inlet pipe and the outlet pipe are equipped with the temperature detection module, the inlet pipe is equipped with the flow detection module, and the air outlet of the cooling tower body is equipped with the wind speed measurement module. The control mechanism is connected to the temperature detection module and is used to control the fan rotation frequency of the cooling tower body to increase or decrease based on the inlet water temperature value, outlet water temperature value and preset temperature threshold detected by the temperature detection module. The control mechanism is connected to the flow detection module and is used to control the water inlet valve of the water inlet pipe to open or close according to the water flow value detected by the flow detection module and the preset flow threshold. The control mechanism is connected to the wind speed measuring module and is used to control the fan rotation frequency of the cooling tower body to increase or decrease according to the wind speed value detected by the wind speed measuring module and the preset wind speed threshold. The control mechanism is connected to the variable flow water distribution device and is used to control the expansion or contraction of the water distribution flow range of the variable flow water distribution device according to the obtained flow range value.

[0006] By adopting the above technical solution, the temperature detection module detects the inlet water temperature (or return water temperature) in the inlet pipe and the outlet water temperature in the outlet pipe; the flow detection module detects the inlet water flow rate of the cooling tower body, and the wind speed measurement module detects the outlet air speed at the air outlet of the cooling tower body; the control mechanism is an intelligent control device that identifies and acquires the inlet water temperature value detected by the temperature detection module, and compares the inlet water temperature value with a preset temperature threshold (i.e., determines whether the inlet water temperature value is within the corresponding inlet water temperature threshold range). Based on the comparison result, the control mechanism increases or decreases the fan rotation frequency of the cooling tower body: if the inlet water temperature value is lower than the inlet water temperature threshold, the fan rotation frequency of the cooling tower body is reduced, and vice versa; thus, the effect of intelligent frequency conversion control of the cooling tower body's load operating frequency is achieved. For example, during the morning, evening, spring, autumn, and winter periods, the cooling tower is not always operated at full load, saving energy consumption; this is beneficial for the cooling tower to achieve the liquid cooling requirements of external equipment while saving electricity under different temperature environments through frequency conversion.

[0007] Furthermore, the control mechanism identifies and acquires the water flow rate value of the inlet pipe detected by the flow detection module, and compares the water flow rate value with a preset flow threshold (i.e., determines whether the water flow rate value is within the corresponding flow threshold range). Based on the comparison result, it controls the opening or closing of the inlet valve of the inlet pipe: if the water flow rate value is lower than the flow threshold, the inlet valve of the inlet pipe is opened wider; otherwise, the inlet valve is closed wider. Further, the control mechanism identifies and acquires the wind speed value of the air outlet of the cooling tower body detected by the wind speed measurement module, and compares the wind speed value with a preset... The system compares wind speed thresholds (i.e., determines whether the wind speed is within the corresponding wind speed threshold range) and controls the fan rotation frequency of the cooling tower body to increase or decrease based on the comparison results. Furthermore, the variable flow water distribution device can control its own liquid spraying and distribution range according to the flow range set by the user, such as adjusting it within the distribution range of 10%-120%. In summary, this application enables automatic, intelligent, and flexible frequency conversion through a variable frequency control mechanism during early morning and evening periods, as well as spring, autumn, and winter, when the cooling tower does not require 100% operating load. This achieves noise reduction, energy saving, and reduced water drift.

[0008] In a preferred embodiment of this application: multiple packing plates are stacked in the air chamber of the cooling tower body, the packing plates are bent, and the two sides of the packing plates are the air inlet surface and the air outlet surface, respectively; water collector strips are provided at opposite ends of the packing plates, the water collector strips on the air inlet surface are inclined at 35° to 70° toward the packing plate, and the water collector strips on the water outlet surface are inclined at 35° to 70° away from the packing plate.

[0009] By adopting the above technical solution, the high-temperature liquid to be cooled is introduced into the air chamber of the cooling tower through the water inlet pipe, and then evenly sprayed onto the top of multiple packing plates by the variable flow water distribution device. The liquid is then adsorbed by the packing plates on both sides of the packing plates to form a water film. This allows the fan to drive the fresh, low-temperature air from outside the cooling tower to blow onto the packing plates. The bent packing plates have a better adsorption effect on cooling water, which can quickly cool the high-temperature liquid to be cooled and improve the cooling effect of the cooling tower. In addition, the water collector bars on both sides of the packing plates are designed with the air inlet side inclined inward at 35° to 70° and the air outlet side inclined outward at 35° to 70°. This helps to maintain smooth air intake and exhaust, reduce resistance, and at the same time minimize the occurrence of water drift phenomenon in the cooling tower.

[0010] In a preferred embodiment of this application: the water inlet pipe includes a main water inlet pipe and a plurality of spaced-apart branch water inlet pipes, one end of the branch water inlet pipe is connected to the main water inlet pipe, and the other end of the branch water inlet pipe is connected to the air chamber of the cooling tower body; the variable flow water distribution device includes a distribution pipe and a multi-layer three-dimensional nozzle; each branch water inlet pipe is connected to a plurality of parallel-arranged distribution pipes, the distribution pipes are connected to the branch water inlet pipes, and each distribution pipe is connected to a plurality of the multi-layer three-dimensional nozzles; the water mist sprayed from the multi-layer three-dimensional nozzles is inclined at 35° to 70° to the air inlet surface of the packing plate.

[0011] By adopting the above technical solutions, multiple inlet branch pipes and multiple rows of parallel water distribution pipes help to achieve uniform water distribution and improve heat exchange efficiency; the multi-layer three-dimensional nozzle design enables the water pump to achieve a large-area spraying effect even with a lower residual pressure, resulting in better water distribution.

[0012] In a preferred embodiment of this application: a water collection tray is provided at the bottom of the cooling tower body, and the water collection tray is equipped with the temperature detection module and an electric heating device; the control mechanism is connected to the electric heating device, and the electric heating device is set with a heating threshold; the temperature detection module is used to detect the water temperature in the water collection tray to obtain a water collection tray temperature detection value; the control mechanism compares the water collection tray temperature detection value with the heating threshold, and issues an early warning and controls the electric heating device to heat when the water collection tray temperature detection value is lower than the heating threshold.

[0013] By adopting the above technical solution, the water temperature in the water collection basin of the cooling tower is prone to freezing when it is below 0℃ in winter. This application uses a temperature detection module to monitor in real time whether the water temperature in the water collection basin is lower than the set temperature, such as 4℃. When the temperature detection module detects that the water temperature in the water collection basin is lower than 4℃, it controls the electric heating device to automatically turn on the power to heat the water collection basin. After the specified heating time, the electric heating device will automatically turn off the power, effectively preventing the cooling tower from freezing due to the low external ambient temperature, which would affect the use of the cooling tower system and cause cooling tower failure. The early warning method also helps users understand the current temperature change of the cooling tower.

[0014] In a preferred embodiment of this application: a plurality of spring shock absorbers are spaced apart at the bottom of the cooling tower body, and the cooling tower body is also equipped with a vibration alarm; the vibration alarm is used to detect the vibration of the cooling tower body to output vibration data, and the vibration alarm outputs a vibration warning signal when the vibration data exceeds a preset vibration threshold.

[0015] By adopting the above technical solution, the cooling tower will vibrate and generate noise due to the operation of fans, water pumps, etc. To reduce the vibration of the main body of the cooling tower, multiple spring vibration dampers are installed, which have a good vibration reduction effect. In addition, a vibration alarm is also installed. The vibration alarm is set with a vibration threshold to monitor the abnormal vibration of the cooling tower during operation. When the vibration data exceeds the vibration threshold, it indicates that the cooling tower is vibrating abnormally and needs to be checked and maintained in time. The vibration warning signal is output to quickly alert the staff that the cooling tower is vibrating abnormally and needs to be dealt with in time.

[0016] The second objective of this invention is achieved by the following technical solution: A smart control method for a cooling tower, applied to a smart control system for a cooling tower as described above, the method comprising: acquiring the inlet water temperature value of the inlet pipe and the outlet water temperature value of the outlet pipe detected by the temperature detection module; controlling the fan rotation frequency of the cooling tower body to increase when the inlet water temperature value is lower than a preset inlet water temperature threshold or the outlet water temperature value is lower than a preset outlet water temperature threshold; and controlling the fan rotation frequency of the cooling tower body to decrease when the inlet water temperature value is higher than a preset inlet water temperature threshold or the outlet water temperature value is higher than a preset outlet water temperature threshold. The system acquires the water flow rate value of the inlet pipe detected by the flow detection module, and controls the inlet valve of the inlet pipe to open wider when the water flow rate value is lower than a preset flow threshold; and controls the inlet valve of the inlet pipe to close narrower when the water flow rate value is higher than the preset flow threshold. The system acquires the wind speed value detected by the wind speed detection module in the air chamber of the cooling tower body, and controls the fan rotation frequency of the cooling tower body to increase when the wind speed value is lower than a preset wind speed threshold; and controls the fan rotation frequency of the cooling tower body to decrease when the wind speed value is higher than the preset wind speed threshold. The variable flow rate distribution device is controlled to expand or shrink the water distribution flow range based on the target water distribution range indicated by the acquired flow range value.

[0017] By adopting the above technical solutions, the cooling tower can be controlled to avoid operating at full load continuously during the morning, evening, spring, autumn, and winter periods. Specifically, the cooling tower control system uses a temperature detection module to detect the inlet and outlet water temperatures and controls the fan rotation frequency of the cooling tower to increase or decrease based on the temperature comparison results. This allows the cooling tower to achieve energy savings while meeting the liquid cooling needs of external equipment under different temperature environments through frequency conversion. Furthermore, the cooling tower control system uses a flow detection module to detect the water flow rate and controls the opening or closing of the inlet valve of the cooling tower's inlet pipe based on the flow rate detection results. The cooling tower control system also uses a wind speed detection module to detect the wind speed at the tower's air outlet and controls the fan rotation frequency of the cooling tower to increase or decrease based on the wind speed detection results. Finally, the variable flow water distribution device can precisely control the distribution range of the liquid to be cooled according to the user-set flow rate range, thereby achieving intelligent and automatic control of the cooling tower as a whole and improving the intelligence of the cooling tower.

[0018] In a preferred embodiment of this application, the intelligent control method further includes: Acquire historical operating data of the cooling tower under different temperature conditions, and construct a cooling tower operation model; The cooling tower operation model determines the initial operating parameters of the cooling tower based on the current ambient temperature and the obtained cooling demand value of the usage scenario. A target optimization algorithm is established for the control mechanism of the cooling tower; based on the target optimization algorithm, global parameter optimization is performed on the initial operating parameters of the cooling tower to obtain the optimized operating parameters of the cooling tower operating model; Energy-saving control of the cooling tower is performed based on the optimized operating parameters.

[0019] By adopting the above technical solution, the cooling tower operation model is a cooling tower energy consumption intelligent agent. By detecting historical operation data of the cooling tower at different times of day and at different temperatures in spring, autumn, and winter, a model representing the relationship between cooling tower energy consumption and operation parameters (i.e., cooling tower operation model) is established. Based on the current ambient temperature and the cooling demand value of the current usage scenario, the initial operation parameters of the cooling tower are determined, that is, the initial operation parameters of the cooling tower are determined based on the current cooling demand value. Then, the initial operation parameters of the cooling tower are globally optimized through a target optimization algorithm to determine the optimized operation parameters based on each operating device inside the cooling tower. The cooling tower is then operated according to the optimized operation parameters, which is beneficial for energy-saving optimization control of the cooling tower.

[0020] In a preferred embodiment of this application, the construction of the cooling tower operation model specifically includes: The cooling tower operation model is established using the following formula: in P is the actual operating power of the cooling tower. t ′ ower This is the rated power of the cooling tower; It is the actual operating power of the cooling tower fan, f t ′ ower This is the rated power of the cooling tower fan; This is the actual operating power of the cooling tower water pump. d0, d1, d2, and d3 are the rated power of the cooling tower water pump; d0, d1, d2, and d3 are the identification coefficients to be fitted. The heat dissipation of the cooling tower is calculated using the following formula: Q tower For the heat dissipation of the cooling tower, m w The air mass flow rate of the cooling tower; m a T represents the water flow rate of the cooling tower's inlet pipe. in T represents the inlet water temperature of the inlet pipe. out E represents the outlet water temperature of the water pipe. S When the temperature drops by T in -T out The evaporation rate of cooling water is α; α is the heat loss coefficient of cooling return water due to evaporation, and α is taken as 600.

[0021] By adopting the above technical solution, the cooling tower operation model is identified and fitted through the identification coefficients to be fitted, so as to obtain a cooling tower operation model that is more suitable for the current cooling tower operation status, so that the cooling tower operation model can adapt to the energy consumption of different models of cooling towers and has higher applicability; by calculating the heat dissipation of the cooling tower, the initial operating parameters of the cooling tower are set based on the cooling amount to be cooled, the heat load of the cooling tower and the environmental conditions set by the user.

[0022] The third objective of this invention is achieved by the following technical solution: A computer device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the intelligent control method for the cooling tower described above.

[0023] The fourth objective of this invention is achieved by the following technical solution: A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the intelligent control method for the cooling tower described above.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The temperature detection module detects the inlet water temperature (or return water temperature) in the inlet pipe and the outlet water temperature in the outlet pipe; the flow detection module detects the inlet water flow rate of the cooling tower body, and the wind speed measurement module detects the outlet air speed at the air outlet of the cooling tower body; the control mechanism is an intelligent control device that identifies and acquires the inlet water temperature value detected by the temperature detection module, and compares the inlet water temperature value with a preset inlet water temperature threshold (i.e., determines whether the inlet water temperature value is within the corresponding inlet water temperature threshold range). Based on the comparison result, the control mechanism increases or decreases the fan rotation frequency of the cooling tower body: if the inlet water temperature value is lower than the inlet water temperature threshold, the fan rotation frequency of the cooling tower body is reduced, and vice versa; thus achieving the effect of intelligent frequency conversion control of the cooling tower body's load operating frequency, such as controlling the cooling tower to not always operate at full load during the morning, evening, spring, autumn, and winter periods, saving energy; it is beneficial to achieve the effect of saving electricity while meeting the liquid cooling needs of external equipment through frequency conversion in different temperature environments. Furthermore, the control mechanism identifies and acquires the water flow value of the inlet pipe detected by the flow detection module, and compares the water flow value with a preset flow threshold (i.e., determines whether the water flow value is within the corresponding flow threshold range). Based on the comparison result, it controls the opening or closing of the inlet valve of the inlet pipe: if the water flow value is lower than the flow threshold, it controls the opening of the inlet valve of the inlet pipe to be larger, and vice versa. Furthermore, the control mechanism identifies and acquires the wind speed value of the air outlet of the cooling tower body detected by the wind speed measurement module, and compares the wind speed value with a preset wind speed threshold (i.e., determines whether the air outlet wind speed is within the corresponding wind speed threshold range). Based on the comparison result, it controls the rotation frequency of the fan of the cooling tower body to be increased or decreased. Moreover, the variable flow water distribution device can control its own liquid spraying and water distribution range according to the flow range value set by the user, such as adjusting it within the water distribution range of 10%-120%. In summary, this application enables automatic, intelligent, and flexible frequency conversion via a frequency converter during early morning and evening hours, as well as during spring, autumn, and winter when the cooling tower does not require 100% operating load, thereby achieving noise reduction, energy saving, and reduced water drift. 2. The high-temperature liquid to be cooled is introduced into the air chamber of the cooling tower through the inlet pipe, and then evenly sprayed onto the top of multiple packing plates by the variable flow water distribution device. The liquid is then adsorbed by the packing plates on both sides of the packing plates, forming a water film. This allows the fan to drive the fresh, low-temperature air from outside the cooling tower to blow onto the packing plates. The bent packing plates have a better adsorption effect on cooling water, which can quickly cool the high-temperature liquid to be cooled and improve the cooling effect of the cooling tower. In addition, the water collector bars on both sides of the packing plates are designed with the air inlet side inclined inward at 35° to 70° and the air outlet side inclined outward at 35° to 70°. This helps to maintain smooth air intake and exhaust, reduce resistance, and at the same time minimize the occurrence of water drift in the cooling tower. 3. The cooling tower operation model is an intelligent energy consumption agent for the cooling tower. By detecting historical operating data of the cooling tower at different times of day and at different temperatures in spring, autumn, and winter, a model representing the relationship between cooling tower energy consumption and operating parameters (i.e., the cooling tower operation model) is established. Based on the current ambient temperature and the cooling demand of the current usage scenario, the initial operating parameters of the cooling tower are determined. Then, the initial operating parameters of the cooling tower are globally optimized using a target optimization algorithm to determine the optimized operating parameters of each operating device inside the cooling tower. The cooling tower is then operated according to the optimized operating parameters, which is beneficial for energy-saving optimization control of the cooling tower. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] In one embodiment, such as Figures 1 to 3 As shown, this application discloses an intelligent control system for a cooling tower, including a cooling tower body 1, a temperature detection module 2, a flow detection module 3, a wind speed measurement module 4, and a control mechanism; the cooling tower body 1 includes a fan 11, a variable flow water distribution device 12, an inlet pipe 13, and an outlet pipe 14; the fan 11 is a 9-blade fan 11, the blade of the fan 11 is connected to the fan disc by a double U-shaped code, and the fan 11 is equipped with a permanent magnet motor bearing, which is beneficial to achieving noise reduction and energy saving; the variable flow water distribution device 12 is connected to the inlet pipe 13, both the inlet pipe 13 and the outlet pipe 14 are equipped with a temperature detection module 2, the inlet pipe 13 is equipped with a flow detection module 3, and the air outlet of the cooling tower body 1 is equipped with a wind speed measurement module 4.

[0029] like Figures 1 to 3 As shown, the control mechanism is connected to the temperature detection module 2 and is used to control the rotation frequency of the fan 11 of the cooling tower body 1 to increase or decrease based on the inlet water temperature value, outlet water temperature value, and preset temperature threshold detected by the temperature detection module 2. The temperature threshold includes the inlet water temperature threshold and the outlet water temperature threshold. For example, when the inlet water temperature value is lower than the inlet water temperature threshold, the rotation frequency of the fan 11 of the cooling tower body 1 is controlled to decrease, and vice versa. This achieves the effect of intelligent frequency conversion control of the load operating frequency of the cooling tower body 1, such as controlling the cooling tower not to run at full load continuously during the morning, evening, spring, autumn, and winter periods, thus saving energy.

[0030] like Figure 2 and Figure 4As shown, the control mechanism is connected to the flow detection module 3 and is used to control the inlet valve of the inlet pipe 13 to open or close according to the water flow value detected by the flow detection module 3 and the preset flow threshold. The inlet valve of the inlet pipe 13 is an electric valve. Specifically, when the water flow value is lower than the flow threshold, the inlet valve of the inlet pipe 13 is opened, and vice versa. The control mechanism is connected to the wind speed measurement module 4 and is used to control the fan 11 of the cooling tower body 1 to increase or decrease its rotation frequency according to the wind speed value detected by the wind speed measurement module 4 and the preset wind speed threshold. The control mechanism is connected to the variable flow water distribution device 12 and is used to control the water distribution flow range of the variable flow water distribution device 12 to expand or shrink according to the obtained flow range value. That is, the variable flow water distribution device 12 can control its own liquid spraying and water distribution range according to the flow range value set by the user, such as adjusting it within the water distribution range of 10%-120%.

[0031] like Figure 1 and Figure 2 As shown, multiple spring dampers 15 are spaced apart at the bottom of the cooling tower body 1, which helps to reduce the vibration generated during the operation of the cooling tower and facilitates the maintenance of the cooling tower. The cooling tower body 1 is also equipped with a vibration alarm 16. The vibration alarm 16 is used to detect the vibration of the cooling tower body 1 and output vibration data. When the vibration data exceeds the preset vibration threshold, the vibration alarm 16 outputs a vibration warning signal. When the vibration data exceeds the vibration threshold, it indicates that the cooling tower vibration is abnormal and needs to be checked and maintenance measures are taken in time. By outputting a vibration warning signal, the staff are quickly alerted that the cooling tower vibration is abnormal and needs to be dealt with in time.

[0032] like Figure 1 and Figure 2 As shown, a water collection tray 17 is installed at the bottom of the cooling tower body 1. The water collection tray 17 is equipped with a temperature detection module 2 and an electric heating device 5. The electric heating device 5 includes an electric heating rod and an electric heating wire. The control mechanism is connected to the electric heating device 5. The electric heating device 5 is set with a heating threshold of 4℃. The temperature detection module 2 is used to detect the water temperature of the water collection tray 17 to obtain the temperature detection value of the water collection tray 17. The control mechanism compares the temperature detection value of the water collection tray 17 with the heating threshold. When the temperature detection value of the water collection tray 17 is lower than the heating threshold, an early warning is issued and the electric heating device 5 is controlled to heat. In winter, when the water temperature in the water collection tray 17 in the cooling tower is lower than 0℃, it is easy for ice to form. The design is that when the temperature detection module 2 detects that the water temperature in the water collection tray 17 is lower than 4℃, the electric heating device 5 is automatically powered on to heat the water collection tray 17. After heating for a fixed time, the electric heating device 5 will automatically turn off the power, effectively preventing the cooling tower from freezing due to the low external ambient temperature, which would affect the use of the cooling tower system.

[0033] like Figure 2 and Figure 5 As shown, the water collection tray 17 is connected to a water supply pipe 171 and an overflow pipe 172. The water supply pipe 171 includes an automatic water supply pipe 171 and a manual water supply pipe 171. The automatic water supply pipe 171 is equipped with a solenoid valve connected to the control mechanism. The control mechanism is connected to a low water level alarm 6 for detecting the water level in the water collection tray 17. The low water level alarm 6 is set with a low water level alarm threshold and issues a warning when the water level in the water collection tray 17 is detected to be lower than the low water level alarm threshold. At this time, the control mechanism automatically opens the solenoid valve to automatically supply water. The control mechanism is equipped with a visual display screen (not shown in the figure). When the low water level alarm 6 issues a warning due to a low water level, a red audible and visual warning signal is displayed on the visual display screen to facilitate timely follow-up and resolution of problems by equipment management personnel.

[0034] like Figure 2 and Figure 6 As shown, the water collection tray 17 is also connected to the return water pipe 173 and the return water pump (not shown in the figure). The return water inlet of the return water pipe 173 is equipped with an anti-vortex filter 7, which is a stainless steel anti-vortex filter. The anti-vortex filter 7 can prevent debris from entering the cooling tower system and at the same time prevent the return water pump at the return water inlet from generating vortices due to high pumping force.

[0035] like Figure 2 , Figures 5 to 8 As shown, multiple packing plates 8 are stacked inside the air chamber 18 of the cooling tower body 1. The packing plates 8 are bent and stacked. In this embodiment, the multiple packing plates 8 are stacked vertically in layers, divided into two stacks and respectively arranged on opposite sides of the cooling tower body 1. The packing plates 8 are bent into a W-shaped corrugated structure. The W-shaped corrugated packing has a better adsorption effect on cooling water, which can make the cooling water of the cooling tower form a film with the largest possible area, thereby improving the cooling effect of the cooling tower. The two sides of the packing plate 8 are the air inlet and air outlet, respectively. Water collector strips 81 are provided at opposite ends. The water collector strips 81 on the air inlet side are inclined at 35° to 70° toward the packing plate 8, and the water collector strips 81 on the water outlet side are inclined at 35° to 70° away from the packing plate 8. In this embodiment, the water collector strips 81 are inclined at 45° on both the water inlet and air outlet sides, so as to keep the air inlet and outlet of the air chamber 18 smooth, reduce the air inlet and outlet resistance, and at the same time minimize the occurrence of cooling tower drift.

[0036] like Figure 4 , Figure 5 and Figure 7As shown, the water inlet pipe 13 includes a main water inlet pipe 131 and multiple spaced-apart branch water inlet pipes 132. One end of the branch water inlet pipe 132 is connected to the main water inlet pipe 131, and the other end of the branch water inlet pipe 132 is connected to the air chamber 18 of the cooling tower body 1. The variable flow water distribution device 12 includes a water distribution pipe 121 and a multi-layer three-dimensional nozzle 122. In this embodiment, the multi-layer three-dimensional nozzle 122 is an ABS three-layer uniform volume three-dimensional nozzle. Each branch water inlet pipe 132 is connected to multiple parallel water distribution pipes 121. In this embodiment, each branch water inlet pipe 132 is connected to three water distribution pipes 121. The water distribution pipes 121 are connected to the branch water inlet pipes 132, and each water distribution pipe 121 is connected to multiple multi-layer three-dimensional nozzles 122. The water mist sprayed from the three-layer three-dimensional nozzles is inclined at 35° to 70° to the air inlet surface of the packing plate 8. In this embodiment, the water mist sprayed from the three-layer three-dimensional nozzles is inclined at 45° to the packing plate 8 (not shown in the figure).

[0037] like Figure 5 As shown, the temperature detection module 2 includes a temperature sensor, the flow detection module 3 includes a flow sensor, and the wind speed measurement module 4 includes a wind speed meter. Each water inlet branch pipe 132 is equipped with a temperature sensor and a water flow sensor. The wind speed meter is located at the air outlet of the cooling tower. The detection data from the temperature sensor, flow sensor, and water flow sensor can all be displayed on the visual display screen of the control mechanism, which is beneficial for users to monitor and manage the operating parameters of the cooling tower.

[0038] The implementation principle of the intelligent control system for a cooling tower in this application embodiment is as follows: the high-temperature liquid to be cooled is introduced into the air chamber 18 of the cooling tower through the water inlet pipe 13, and then evenly sprayed onto the top of multiple packing plates 8 through the variable flow water distribution device 12, and is adsorbed on both sides of the packing plates 8 to form a water film, so that the fan 11 can drive the fresh cold air outside the cooling tower to blow towards the packing plates 8; the fresh cold air is transformed into high-temperature and high-humidity gas through the air chamber 18 and then discharged outside the cooling tower. According to the law of conservation of energy, when the high-temperature water to be cooled flows from the top of the packing plate 8 to the water collection tray 17, it becomes low-temperature water.

[0039] During the operation of a cooling tower, it is necessary to prevent it from operating at full load continuously during the morning, evening, spring, autumn, and winter seasons. Therefore, an intelligent control system adaptable to different ambient temperatures is required. Specifically, the cooling tower control system uses a temperature detection module 2 to detect the inlet and outlet water temperatures and adjusts the frequency of the cooling tower's fan 11 based on the temperature comparison results. This allows the cooling tower to achieve energy savings while meeting the liquid cooling needs of external equipment under varying temperature conditions through frequency conversion. Furthermore, the cooling tower control system uses a flow detection module 3 to detect the water flow rate and adjusts the opening and closing of the inlet valve on the cooling tower's inlet pipe 13 based on the flow rate detection results. The cooling tower control system also uses a wind speed detection module to detect the wind speed at the tower's outlet and adjusts the frequency of the cooling tower's fan 11 based on the wind speed detection results. Finally, the variable flow water distribution device 12 can precisely control the distribution range of the liquid to be cooled according to the user-defined flow rate range, thus achieving intelligent automatic control of the cooling tower and improving its overall intelligence.

[0040] In one embodiment, a smart control method for a cooling tower is provided, which is applied to a smart control system for a cooling tower as described above.

[0041] Reference Figure 9 Intelligent control methods for cooling towers include: S1: Obtain the inlet water temperature value of the inlet pipe and the outlet water temperature value of the outlet pipe detected by the temperature detection module, and control the fan rotation frequency of the cooling tower body to increase when the inlet water temperature value is lower than the preset inlet water temperature threshold or the outlet water temperature value is lower than the preset outlet water temperature threshold; and control the fan rotation frequency of the cooling tower body to decrease when the inlet water temperature value is higher than the preset inlet water temperature threshold or the outlet water temperature value is higher than the preset outlet water temperature threshold.

[0042] Specifically, by controlling the fan rotation frequency of the cooling tower to increase or decrease based on the temperature comparison results, it is beneficial to achieve the effect of saving energy while meeting the liquid cooling needs of external equipment through frequency conversion under different temperature environments.

[0043] S2: Obtain the water flow value of the inlet pipe detected by the flow detection module, and when the water flow value is lower than the preset flow threshold, control the inlet valve of the inlet pipe to open wider; when the water flow value is higher than the preset flow threshold, control the inlet valve of the inlet pipe to close narrower.

[0044] Specifically, controlling the opening or closing of the inlet valve of the cooling tower's inlet pipe based on the water flow detection results helps determine the actual flow rate of the cooling tower during operation.

[0045] S3: Obtain the wind speed value in the air chamber of the cooling tower body detected by the wind speed detection module, and control the fan rotation frequency of the cooling tower body to increase when the wind speed value is lower than the preset wind speed threshold; control the fan rotation frequency of the cooling tower body to decrease when the wind speed value is higher than the preset wind speed threshold.

[0046] Specifically, if the fan speed is too low, it will not achieve the expected cooling effect, while if the fan speed is too high, it will cause the fan to operate at excessive efficiency for a long time, which will not extend the service life of the fan. The control mechanism helps to keep the air speed of the cooling tower within the specified air speed threshold range, which facilitates the maintenance of the cooling tower.

[0047] S4: Control the expansion or contraction of the water distribution flow range of the variable flow water distribution device based on the target water distribution range indicated by the acquired flow range value.

[0048] In this embodiment, the variable flow water distribution device can be customized based on the user's requirements for various water flow ranges. The variable flow water distribution device can achieve large-area spraying and uniform water distribution even under low residual pressure conditions of the water pump. It reduces the occurrence of cooling tower overflow due to excessive water intake and also prevents uneven water distribution due to reduced water intake.

[0049] Specifically, the cooling tower achieves intelligent and automatic control as a whole, thus improving the overall intelligence of the cooling tower.

[0050] In one embodiment, such as Figure 10 As shown, the intelligent control method for cooling towers also includes: S10: Obtain historical operating data of the cooling tower under different temperature conditions and build a cooling tower operation model.

[0051] In this embodiment, different temperature data refer to different temperature values ​​for different time periods such as morning, evening, spring, autumn, and winter. Historical operating data includes historical temperature data (including historical inlet water temperature value and historical outlet water temperature value), historical water flow data, historical cooling tower heat load data, actual operating power of the cooling tower, cooling tower energy consumption, actual operating power of the water pump, and historical temperature data, etc.; the cooling tower operation model is a cooling tower energy consumption intelligent agent.

[0052] S20: The cooling tower operation model determines the initial operating parameters of the cooling tower based on the current ambient temperature and the obtained cooling demand values ​​of the usage scenario.

[0053] In this embodiment, the ambient temperature is the temperature data of the operating environment of the cooling tower detected by the current temperature sensor; the cooling demand value is the number of cooling towers that are turned on in the current usage scenario and the required cooling capacity of each cooling tower; the required cooling capacity includes the cooling water flow rate and the required outlet water temperature.

[0054] Specifically, the heat load value and ambient temperature value of each cooling tower are input into the cooling tower operation model to output the initial operating parameters of the cooling tower, and the operation settings of the cooling tower are made based on the initial operating parameters.

[0055] S30: Establish the target optimization algorithm for the control mechanism of the cooling tower; based on the target optimization algorithm, perform global parameter optimization on the initial operating parameters of the cooling tower to obtain the optimized operating parameters of the cooling tower operating model.

[0056] In this embodiment, the target optimization algorithm is the PSO particle swarm optimization algorithm; the operating parameter optimization condition is to minimize the total operating power consumption of each cooling tower while ensuring that the cooling tower reaches the required cooling capacity. The total operating power consumption includes the total operating power consumption of the fan and the total operating power consumption of the water pump.

[0057] Specifically, the cooling tower operation model is used to determine the total cooling capacity output by the cooling tower model when it equals the required cooling capacity, the operating power consumption of the cooling tower, and the number of cooling towers to be turned on. Multiple data combinations of the inlet and outlet water temperatures for each cooling tower are generated, and these combinations are used as the optimization dataset. The cooling tower operation model performs optimization calculations based on this dataset to obtain the minimum power consumption of the cooling tower, as well as the corresponding inlet and outlet water temperatures. This yields the inlet and outlet water temperatures of the chilled water at the minimum power consumption, representing the optimized operating parameters of the cooling tower.

[0058] S40: Energy-saving control of cooling towers based on optimized operating parameters.

[0059] Specifically, operating the cooling tower according to the optimized operating parameters is beneficial for energy-saving optimization control of the cooling tower.

[0060] In one embodiment, step S1 involves constructing a cooling tower operation model, specifically including: S101: The cooling tower operation model is established using the following formula: in P is the actual operating power of the cooling tower. t ′ ower This is the rated power of the cooling tower; It is the actual operating power of the cooling tower fan, f t ′ ower This is the rated power of the cooling tower fan; This is the actual operating power of the cooling tower water pump. d0, d1, d2, and d3 are the rated power of the cooling tower water pump; d0, d1, d2, and d3 are the identification coefficients to be fitted.

[0061] Specifically, the cooling tower operation model is identified and fitted using the identification coefficients to be fitted, so as to obtain a cooling tower operation model that is more suitable for the current operating state of the cooling tower, making the cooling tower operation model adaptable to the energy consumption of different models of cooling towers and having higher applicability.

[0062] S102: The heat dissipation of the cooling tower is calculated using the following formula: Q tower For the heat dissipation of the cooling tower, m w The air mass flow rate of the cooling tower; m a T represents the water flow rate of the cooling tower's inlet pipe. in T represents the inlet water temperature of the inlet pipe. out E represents the outlet water temperature of the water pipe. S When the temperature drops by T in -T out The evaporation rate of cooling water is α; α is the heat loss coefficient of cooling return water due to evaporation, and α is taken as 600.

[0063] Specifically, cop is the coefficient of performance of the cooling tower, Q ′ a ′ ll P represents the total heat dissipation of the cooling tower. all Q represents the total cooling capacity of the cooling tower. ′ all The total power consumption for cooling tower cooling can be determined from the historical operating parameters of the cooling tower.

[0064] Specifically, the cooling efficiency of the cooling tower Among them, T w For external ambient temperature, N i Let β1 and β2 represent the number of operating cooling towers, and β1 and β2 be the fitting coefficients to be determined. By employing a linear regression algorithm combined with the results of operating cooling towers under the same ambient temperature conditions and the same number of operating cooling towers, the specific values ​​of β1 and β2 are obtained. This allows for updating the cooling tower's cooling efficiency value in the cooling tower operation model based on the actual usage of each cooling tower within a specified time period. The optimal cooling tower operation model coefficients, which conform to actual usage conditions, are obtained through linear regression, improving the accuracy of the cooling tower parameter calculation results.
