Description

Technical Field

[0001] This utility model relates to the field of circulating water cooling tower technology, and more specifically, to a circulating water cooling tower system. Background Technology

[0002] Currently, the main dust control technology for circulating water cooling towers involves adding filters to the air intake on the outer facade of the tower to enhance the filtration effect on sand, dust, and other impurities.

[0003] However, this protective method is not comprehensive. Sand, dust, and other impurities can still enter the tower from the exhaust vents and other unprotected areas on the tower's exterior. Furthermore, when the filter becomes clogged, negative pressure is created at the air inlet, increasing the pressure difference before and after the filter. This forces the circulating water cooling tower's fans to increase their load to maintain stable circulating water temperature, resulting in additional power consumption. Cleaning also requires shutting down the corresponding fans and manually removing or replacing the filters. Both cleaning and replacement require manual labor and a certain number of spare filters, leading to high costs for long-term maintenance and replacement. On the other hand, filters are prone to freezing in winter, causing a sharp drop in filtration efficiency and further increasing maintenance costs and difficulty. Utility Model Content

[0004] This invention provides a circulating water cooling tower system to solve the problems of existing technologies that only install filters at the air inlet for protection, resulting in incomplete protection, poor protection effect, and high maintenance costs.

[0005] To address the aforementioned problems, this utility model provides a circulating water cooling tower system. The circulating water cooling tower system includes a tower body and a cleaning device. The top of the tower body has an exhaust port, and the outer periphery of the tower body has an air inlet. The cleaning device includes a first cleaning pipe and a second cleaning pipe sharing the same air inlet pipe, which supplies cleaning gas. The first cleaning pipe is located at the top of the tower body and has multiple first jet ends arranged around the exhaust port. The jet direction of any one of the first jet ends is towards the center line of the exhaust port and is inclined relative to the center line of the exhaust port. The second cleaning pipe is at least partially arranged around the outer periphery of the tower body above the air inlet and has multiple second jet ends corresponding to the air inlet above the air inlet. The jet direction of the multiple second jet ends is parallel to the center line of the tower body and vertically downward.

[0006] Furthermore, the cleaning device also has a third cleaning pipeline that shares the same air inlet pipeline with the first cleaning pipeline and the second cleaning pipeline. The third cleaning pipeline is at least partially arranged around the outer periphery of the tower body and located on the side of the second cleaning pipeline near the air inlet. The third cleaning pipeline has multiple third jet ends, and the jet direction of the multiple third jet ends is parallel to the center line of the tower body and vertically downward.

[0007] Furthermore, the jetting directions of the multiple second jetting ends and the jetting directions of the multiple third jetting ends are parallel to each other and alternate in pairs on the outer periphery of the tower body.

[0008] Furthermore, the intake pipe includes a hot flow section, a cold flow section, and a manifold section. The outlet of the hot flow section, the outlet of the cold flow section, and the inlet of the manifold section are connected to the same location. The outlet of the manifold section is connected to the inlet of the first cleaning pipe and the inlet of the second cleaning pipe at the same location. The hot flow section is used to provide cleaning hot flow, and the cold flow section is used to provide cleaning cold flow.

[0009] Furthermore, the cleaning device also includes a fourth cleaning pipe and a manual cleaning hose. One end of the fourth cleaning pipe is connected to the manifold section, and the other end of the fourth cleaning pipe extends to the outer periphery of the tower body located below the air inlet and has multiple adapter ends. The manual cleaning hose is detachably hung on the outer periphery of the tower body, and the manual cleaning hose can be detachably connected to any adapter end.

[0010] Furthermore, the location where the hot flow pipe section, cold flow pipe section, and manifold section are connected is the first connection position; the location where the fourth cleaning pipe is connected to the manifold section is the second connection position; and the location where the manifold section, the first cleaning pipe, and the second cleaning pipe are connected is the third connection position. The circulating water cooling tower system also includes solenoid valves. A solenoid valve is correspondingly installed on the manifold section between the hot flow pipe section, the cold flow pipe section, the first connection position, and the second connection position; and a solenoid valve is correspondingly installed on the manifold section between the second connection position and the third connection position.

[0011] Furthermore, the circulating water cooling tower system also includes a control module and a monitoring module. The control module, the monitoring module, and multiple solenoid valves are all electrically connected to each other, so as to control the opening and closing of multiple solenoid valves through the monitoring status of the monitoring module.

[0012] Furthermore, the monitoring module includes at least one of an air quality monitor, an anemometer, a turbidity meter, and a packing thermometer. The air quality monitor and anemometer are located on one side of the tower body to monitor the environmental conditions of the tower body. The turbidity meter has a detection end that extends into the water collection pool inside the tower body to monitor the turbidity of the water collection pool. The tower body has a packing layer located above the air inlet, and the packing thermometer is set corresponding to the packing layer to monitor the temperature of the packing layer.

[0013] Furthermore, the cleaning device also includes a pressure reducing valve installed on the manifold section, and the control module is electrically connected to the pressure reducing valve.

[0014] Furthermore, the cleaning device also includes a filter installed on the manifold section.

[0015] The present invention provides a circulating water cooling tower system, comprising a tower body and a cleaning device. The top of the tower body has an exhaust port, and the outer periphery of the tower body has an air inlet. The cleaning device includes a first cleaning pipe and a second cleaning pipe sharing the same air inlet pipe, which supplies cleaning gas. The first cleaning pipe is located at the top of the tower body and has multiple first jet ends arranged around the exhaust port. The jet direction of any one of the first jet ends is towards the center line of the exhaust port and is inclined relative to the center line of the exhaust port. The second cleaning pipe is at least partially arranged around the outer periphery of the tower body above the air inlet and has multiple second jet ends corresponding to the air inlet above the air inlet. The jet direction of the multiple second jet ends is parallel to the center line of the tower body and vertically downward.

[0016] This solution supplies cleaning gas to the first and second cleaning pipelines via the intake pipe. The cleaning gas passes through multiple first jet nozzles in the first cleaning pipeline to prevent dust, remove dust, or de-ic at the exhaust port. Similarly, the cleaning gas passes through multiple second jet nozzles in the second cleaning pipeline to prevent dust, remove dust, or de-ic at least the air inlet and the area surrounding the tower body below it. Specifically, the cleaning gas forms a protective airflow (air curtain) at the tower's exhaust port, air inlet, and the area below the air inlet on the tower's exterior facade. This protective airflow (air curtain) effectively prevents sand and other impurities from being easily carried into the tower during strong winds and dusty weather. Simultaneously, the protective airflow (air curtain) also removes dust or icing at the tower's exhaust port, air inlet, and the area below the air inlet on the tower's exterior facade. This improves the comprehensiveness and reliability of tower protection. Compared to adding filters at the air inlet and exhaust port, this solution optimizes dust prevention, eliminating the need for filter installation and replacement, thus reducing maintenance costs while maintaining dust prevention effectiveness. On the other hand, the intake pipe supplies gas and forms an air curtain at the air inlet, so that the air inlet can always be in a positive pressure state and there will be no negative pressure at the air inlet. This helps to reduce the intake resistance, so that the fan of the circulating water cooling tower system does not need to increase the electrical load, thereby reducing the energy consumption of intake.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] like Figure 1 As shown, this utility model provides a circulating water cooling tower system, which includes a tower body 10 and a cleaning device 20. The top of the tower body 10 has an exhaust port 101, and the outer periphery of the tower body 10 has an air inlet 102. The cleaning device 20 includes a first cleaning pipe 22 and a second cleaning pipe 23 that share the same air intake pipe 21. The air intake pipe 21 supplies cleaning gas. The first cleaning pipe 22 is located at the top of the tower body 10 and has a plurality of first jet ends 221 arranged around the exhaust port 101. The jet direction of any one of the first jet ends 221 is towards the center line of the exhaust port 101 and is inclined relative to the center line of the exhaust port 101. The second cleaning pipe 23 is at least partially arranged around the outer periphery of the tower body 10 above the air inlet 102 and has a plurality of second jet ends 231 above the air inlet 102. The jet direction of the plurality of second jet ends 231 is parallel to the center line of the tower body 10 and vertically downward.

[0027] In this embodiment, cleaning gas is supplied to the first cleaning pipe 22 and the second cleaning pipe 23 through the air inlet pipe 21. The cleaning gas achieves dust prevention, dust removal, anti-icing and de-icing at the exhaust port 101 through multiple first jet ends 221 of the first cleaning pipe 22. The cleaning gas achieves dust prevention, dust removal, anti-icing and de-icing at least the air inlet 102 and the outer periphery of the tower body 10 below it through multiple second jet ends 231 of the second cleaning pipe 23. Specifically, the cleaning gas forms a protective airflow (air curtain) in the area below the exhaust vent 101, air inlet 102, and air inlet 102 on the exterior of the tower 10. This protective airflow (air curtain) effectively prevents dust and other impurities from being easily carried into the tower 10 during strong winds and dusty weather. At the same time, the protective airflow (air curtain) can also remove dust or ice from the exhaust vent, air inlet 102, and air inlet 102 on the exterior of the tower 10, which helps to improve the comprehensiveness and reliability of the protection of the tower 10. Compared with adding filters at the air inlet 102 and exhaust vent 101, this method optimizes the dust prevention and eliminates the need to install or replace filters, thus reducing maintenance costs while ensuring the dust prevention effect. On the other hand, the air intake pipe 21 supplies gas and forms an air curtain at the air inlet 102, so that the air inlet 102 can always be in a positive pressure state and there will be no negative pressure at the air inlet 102. This helps to reduce the air intake resistance, so that the fan of the circulating water cooling tower system does not need to increase the electrical load, thereby reducing the energy consumption of air intake.

[0028] Understandably, the gas source for the intake pipe 21 can be an air separation unit. The air from the air compressor outlet, cooled by the air-cooling tower, is approximately 5°C cold air, which can significantly reduce the circulating water temperature and further reduce the fan energy consumption of the circulating water cooling tower system. Furthermore, during winter, the 90°C hot air from the air compressor outlet of the air separation unit can be used for hot air mixing to prevent ice buildup on the tower body 10.

[0029] Specifically, the second cleaning pipe 23 shares the same third cleaning pipe 24 as the same air intake pipe 21. The third cleaning pipe 24 is at least partially arranged around the outer periphery of the tower body 10 and located on the side of the second cleaning pipe 23 near the air inlet 102. The third cleaning pipe 24 has multiple third jet ends 241, and the jet direction of the multiple third jet ends 241 is parallel to the center line of the tower body 10 and vertically downward.

[0030] In this embodiment, by setting the third cleaning pipe 24 closer to the air inlet 102, the dust prevention, dust removal, anti-icing, and de-icing effects at the air inlet 102 are further improved. Specifically, in this embodiment, the third cleaning pipe 24 is set only above the air inlet 102, while the second cleaning pipe 23 can also be set only above the air inlet 102, or it can be set around the outer periphery of the tower body 10. When the second cleaning pipe 23 is set around the outer periphery of the tower body 10, its protection and cleaning of the outer periphery of the tower body 10 is more comprehensive and reliable.

[0031] In this embodiment, the number of air inlets 102, the number of air outlets 101, and their arrangement can be adjusted according to the actual situation. In this embodiment, there are multiple air inlets 102 arranged in the same row, and two air outlets 101 arranged in parallel at intervals on the top of the tower body 10.

[0032] It should be noted that the configuration of the first cleaning pipe 22, the second cleaning pipe 23, and the third cleaning pipe 24 can be adjusted according to the actual situation. Similarly, the number, distribution, and jet direction of the multiple first jet ends 221, multiple second jet ends 231, and multiple third jet ends 241 can be adjusted according to the actual situation.

[0033] Furthermore, the jetting directions of the multiple second jet ends 231 and the multiple third jet ends 241 are parallel to each other and alternate in pairs on the outer periphery of the tower body 10. This alternating jetting distribution makes the jetting coverage of the air inlet 102 more uniform, effectively preventing dust from accumulating on the outer periphery of the tower body, reducing ice formation, and improving dust prevention, dust removal, and de-icing effects.

[0034] like Figure 1 As shown, the intake pipe 21 includes a hot flow section 211, a cold flow section 212, and a manifold section 213. The outlet of the hot flow section 211, the outlet of the cold flow section 212, and the inlet of the manifold section 213 are connected to the same location. The outlet of the manifold section 213 is connected to the inlet of the first cleaning pipe 22 and the inlet of the second cleaning pipe 23 at the same location. The hot flow section 211 is used to provide cleaning hot flow, and the cold flow section 212 is used to provide cleaning cold flow.

[0035] This configuration allows for the switching of hot flow pipe section 211 and cold flow pipe section 212 to replace dust prevention and de-icing functions. It enables flexible adjustment of the jet temperature according to different environmental conditions, providing both dust and ice prevention. This is suitable for regions with significant climate changes and effectively prevents tower body 10 malfunctions caused by freezing. At the same time, in the high temperatures of summer, the cold flow reduces dust adhesion, ensuring the efficient operation of tower body 10 under different climatic conditions throughout the year.

[0036] Understandably, when the cold air stream is introduced, it blows through the exhaust vent 101, the air inlet 102, and the area below the air inlet 102 on the outer periphery of the tower body 10 to achieve dust removal. The air curtain formed by the blowing also serves as a dust prevention function. When the hot air stream is introduced, it blows through the exhaust vent 101, the air inlet 102, and the area below the air inlet 102 on the outer periphery of the tower body 10, achieving both dust removal and de-icing effects. The air curtain formed by the blowing serves both as a dust prevention function and as an anti-icing (anti-icing) function.

[0037] like Figure 1 As shown, the cleaning device 20 also includes a fourth cleaning pipe 25 and a manual cleaning hose 26. One end of the fourth cleaning pipe 25 is connected to the manifold section 213, and the other end of the fourth cleaning pipe 25 extends to the outer periphery of the tower body 10 located below the air inlet 102 and has multiple adapter ends 251. The manual cleaning hose 26 is detachably hung on the outer periphery of the tower body 10, and the manual cleaning hose 26 can be detachably connected to any adapter end 251.

[0038] This design increases the flexibility of cleaning, allowing operators to manually clean the desired location using the hand-held cleaning hose 26. Specifically, in this embodiment, there are multiple adapter ends 251 spaced apart along the circumference of the tower body 10, and at least two hand-held cleaning hoses 26 are coiled around the outer circumference of the tower body 10 at intervals. When manual cleaning is required, one end of the hand-held cleaning hose 26 closest to the cleaning location is attached to the adapter end 251 via the adapter 34. Then, the hand-held cleaning hose 26 can be unfolded and the cleaning location can be cleaned, which helps to improve the comprehensiveness and reliability of the cleaning.

[0039] The first connection position is where the hot flow pipe section 211, the cold flow pipe section 212, and the manifold section 213 are connected. The second connection position is where the fourth cleaning pipe 25 is connected to the manifold section 213. The third connection position is where the manifold section 213, the first cleaning pipe 22, and the second cleaning pipe 23 are connected. The circulating water cooling tower system also includes a solenoid valve 31. A solenoid valve 31 is correspondingly installed on the hot flow pipe section 211, the cold flow pipe section 212, and the manifold section 213 between the first and second connection positions. A solenoid valve 31 is correspondingly installed on the manifold section 213 between the second and third connection positions.

[0040] In this embodiment, the first cleaning pipeline 22, the second cleaning pipeline 23, and the third cleaning pipeline 24 are always connected in pairs. The solenoid valve 31 installed on the manifold section 213 between the hot flow section 211, the cold flow section 212, the first connection position, and the second connection position can realize the rapid switching between cleaning cold flow and cleaning hot flow. The solenoid valve 31 on the manifold section 213 between the second connection position and the third connection position can realize the rapid switching between manual cleaning pipeline (fourth cleaning pipeline 25) and automatic cleaning pipeline (first cleaning pipeline 22, second cleaning pipeline 23, and third cleaning pipeline 24), realizing semi-automatic control of cleaning, which greatly reduces the frequency and labor intensity of manual operation.

[0041] like Figure 1 As shown, the circulating water cooling tower system also includes a control module 40 and a monitoring module. The control module 40 is electrically connected to the monitoring module and multiple solenoid valves 31, so as to control the opening and closing of multiple solenoid valves 31 through the monitoring status of the monitoring module.

[0042] Specifically, the control module 40 has a corresponding signal input terminal 401 and a signal output terminal 402. The monitoring module is electrically connected to the signal input terminal 401, and the signal output terminal 402 is electrically connected to multiple solenoid valves 31. It can be understood that the combination of the control module 40 and the monitoring module enables the circulating water cooling tower system to automatically adjust its cleaning strategy based on real-time environmental and internal conditions. This is suitable for circulating water cooling tower systems requiring intelligent management. Through intelligent management, the system can precisely control the cleaning process and avoid resource waste.

[0043] Furthermore, the monitoring module includes at least one of an air quality monitor 51, an anemometer 52, a turbidity meter 53, and a packing thermometer 54. The air quality monitor 51 and anemometer 52 are located on one side of the tower body 10 to monitor the environmental conditions surrounding the tower body 10. The turbidity meter 53 has a detection end that extends into the water collection pool inside the tower body 10 to monitor the turbidity of the water collection pool. The tower body 10 has a packing layer located above the air inlet 102, and the packing thermometer 54 is located corresponding to the packing layer to monitor the temperature of the packing layer. The addition of these monitoring devices enables the system to comprehensively understand the operating status of the cooling tower, providing accurate data for automated control, so that the control module 40 can adjust the cleaning strategy in a timely manner. It is understood that the selection and setting of the monitoring devices in the monitoring module can be adaptively adjusted according to actual conditions and are not limited to the aforementioned monitoring devices.

[0044] like Figure 1The cleaning device 20 also includes a pressure reducing valve 32 installed on the manifold section 213, and the control module 40 is electrically connected to the pressure reducing valve 32. This configuration ensures that the gas pressure flowing from the intake pipe 21 to the automatic cleaning pipes (first cleaning pipe 22, second cleaning pipe 23, and third cleaning pipe 24) is always within a safe range, preventing overpressure and contributing to stability.

[0045] Furthermore, the cleaning device 20 also includes a filter 33 installed on the manifold section 213. This arrangement allows the filter 33 to remove impurities from the gas flowing from the inlet pipe 21 to the automatic cleaning pipes (first cleaning pipe 22, second cleaning pipe 23, and third cleaning pipe 24), protecting the tower body 10 from unnecessary contamination.

[0046] In summary, this utility model provides a circulating water cooling tower system. The control module 40 opens and closes multiple solenoid valves according to the monitoring status of the monitoring module to realize the switching between the automatic cleaning pipeline (first cleaning pipeline 22, second cleaning pipeline 23, third cleaning pipeline 24) and the manual cleaning pipeline (fourth cleaning pipeline 25) of the cleaning device (only one or both can be opened at the same time), thereby realizing the dust prevention, dust removal, anti-icing and de-icing cleaning of the exhaust port 101, the air inlet 102 of the tower body 10 and the area below the air inlet 102 on the outer facade of the tower body 10.
