Description

Technical Field

[0001] The present invention relates to the technical field of safety, energy conservation, greenness, and environmental protection of circulating cooling water, and specifically relates to a constant-pressure energy-saving operation device for circulating water. Background Art

[0002] The overall goal of this project is to solve and improve the impact and interference of the production fluctuations of the industrial main process device on the circulating water system, thereby causing high energy consumption and high failure rate of the industrial circulating cooling water system. Although China's national economy has achieved rapid leapfrog development, the attention paid to the circulating cooling water system that directly provides cooling services for the industrial main process device is obviously insufficient and very lagging. Therefore, due to many intractable problems such as high energy consumption and instability in the industrial circulating cooling water system, it has been plaguing industrial users, and they have also paid a heavy economic and energy consumption price for this. Currently, the main methods for pressure control of circulating cooling water at home and abroad are methods and measures such as adjusting the inlet and outlet valves of the water pump, adjusting the inlet valve of the main process device, adjusting the upper tower valve, and setting a voltage stabilizing tank voltage stabilizing device;

[0003] All of the above current methods for pressure control of circulating cooling water at home and abroad cannot completely solve the problems of safety, stability, energy conservation, greenness, and environmental protection of the circulating water system. The production fluctuations of the industrial main process device impact and interfere with the circulating water system, thereby causing high energy consumption and high failure rate of the industrial circulating cooling water system. Devices such as water pumps, valves, and the main process are subjected to unstable water pressure impacts, with significantly insufficient service life and significantly high failure rates. The maintenance and repair costs are uncontrollable. The water volume and water pressure of the circulating water system are unstable, significantly increasing the safety and quality risks of the water-using main device. The circulating water pressure fluctuates frequently, and the operation tasks of water pumps, motors, valves, etc. are arduous, which is not conducive to the physical and mental health of front-line operators and is also not conducive to streamlining operation positions. Therefore, we propose a constant-pressure energy-saving operation device for circulating water. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A constant-pressure energy-saving operation device for circulating water, including a cooling tower main body, wherein a fixing plate is fixedly connected to the inner wall of the cooling tower main body, an electric fan is fixedly connected to one end of the fixing plate away from the cooling tower main body, a condensation mechanism is fixedly connected to the inner wall of the cooling tower main body, a water outlet pipe is communicated with one side of the cooling tower main body, a spray head is communicated with the water outlet pipe, a flow buffering mechanism is fixedly connected to the inner wall of the cooling tower main body, a constant-pressure mechanism is communicated with one end of the water outlet pipe away from the cooling tower main body, a water pipe is communicated with the bottom of the constant-pressure mechanism, a circulating water pump is communicated with the bottom of the water pipe, a water inlet pipe is communicated with the water inlet of the circulating water pump, a water pool is communicated with one end of the water inlet pipe away from the circulating water pump, air holes are opened on the outer side of the cooling tower main body, and the top of the water pool is communicated with the bottom of the cooling tower main body;

[0005] The condensation mechanism includes a connecting plate and a first rotating rod. A first folding hose is fixedly connected to the bottom of the connecting plate. A first spring is fixedly connected to the bottom of the connecting plate. The bottom of the first folding hose is fixedly connected to a corrugated sheet. When the remaining steam is discharged through the air holes of the corrugated sheet, it impacts the bottom surface of the corrugated sheet made of elastic metal, promoting the aggregation and growth of tiny water droplets in the steam and causing them to slide off, reducing the water vapor carried out, further recovering water, and improving the water recovery rate. A second folding hose is fixedly connected to the top of the corrugated sheet. The first folding hose is sleeved outside the first spring, and the second folding hose is sleeved outside the second spring, isolating water vapor and preventing the springs from rusting and losing elasticity, ensuring the durability of the buffering effect. A second spring is fixedly connected to the top of the corrugated sheet. The first and second springs at the top of the corrugated sheet can buffer the impact of the airflow, prevent the corrugated sheet from being damaged, and ensure its normal operation. Air holes are opened at the top of the corrugated sheet. One end of the first rotating rod is fixedly connected to the driving shaft of the motor. An annular baffle is sleeved and rotatably connected to the first rotating rod. A rubber conveyor belt is sleeved and drivingly connected to the first rotating rod. A second rotating rod is rotatably connected to the inner side of the annular baffle. One end of the first rotating rod penetrates and is fixedly connected to a first rotating plate. One end of the second rotating rod penetrates and is fixedly connected to a second rotating plate. The water vapor generated by the cooling of hot water is extracted upward. When it encounters the first rotating plate and the second rotating plate, the water vapor adheres to them and cools into water droplets, which is conducive to the preliminary collection and recovery of water. The motor drives the first rotating rod to rotate, and by means of friction, drives the rubber conveyor belt and the second rotating rod, causing the second rotating plate to rotate, which can make the water droplets condensed on the first rotating plate and the second rotating rod fall better, and at the same time prevent poor ventilation, ensuring that the entire cooling process can be carried out continuously and effectively, and guaranteeing the cooling effect. The side of the connecting plate is fixedly connected to the inner wall of the cooling tower body. The side of the corrugated sheet is fixedly connected to the inner wall of the cooling tower body. The top of the second folding hose is fixedly connected to the inner wall of the cooling tower body. The top of the second spring is fixedly connected to the inner wall of the cooling tower body. One end of the first rotating rod penetrates the cooling tower body and is rotatably connected to the cooling tower body. One side of the motor is fixedly connected to one side of the cooling tower. One end of the second rotating rod penetrates the cooling tower body and is rotatably connected to the cooling tower body. The side of the annular baffle away from the rubber conveyor belt is fixedly connected to the inner wall of the cooling tower body. The bottom of the first spring is fixedly connected to the top of the corrugated sheet.

[0006] Furthermore, the flow slowing mechanism includes a folding plate, a guide plate and an air guide plate. The guide plate guides the direction of the water flow and cooperates with the folding plate to allow the water flow to slide obliquely downward, effectively increasing the contact time between the water flow and the cold air and improving the possibility of heat exchange. The bending structure of the folding plate ensures that the water flow will not overflow outside the cooling tower during the sliding process. At the same time, its rectangular holes can allow cold air to pass through to achieve the intersection of gas and liquid. The air guide plate guides the flow direction of the cold air obliquely upward so that the cold air can directly intersect with the water flow in the opposite direction, thereby improving the heat exchange efficiency and accelerating the heat transfer. A rectangular hole is provided on one side of the folding plate, and a ventilation hole is provided on the side of the air guide plate close to the folding plate. When the cold air enters and exits the circular groove through the ventilation hole, the air flow speed is accelerated and the pressure is reduced, which not only promotes the evaporation of water vapor, but also To take away more heat and further improve the cooling efficiency, a circular groove is opened on the top of the air guide plate. After part of the water flows into the circular groove, the water flow rate slows down and the residence time is prolonged due to the narrow channel of the circular groove, so that the cold air has more time to fully absorb the heat of the water flow and enhance the heat exchange effect. A filter plate is fixedly connected to the bottom of the air guide plate. The filter plate prevents the cold air from dispersing from below, and prompts the cold air to move upward to avoid the problem of uneven heat exchange or reduced efficiency caused by the dispersion of cold air. One side of the folding plate is fixedly connected to the inner wall of the cooling tower body, one side of the guide plate is fixedly connected to the inner wall of the cooling tower body, one side of the air guide plate is fixedly connected to the inner wall of the cooling tower body, and the side of the filter plate is fixedly connected to the inner wall of the cooling tower body.

[0007] Furthermore, the constant pressure mechanism includes a housing. An air vent is provided on the side of the housing. A motor is fixedly connected to the bottom of the inner wall of the housing. A lead screw is fixedly connected to the drive shaft of the motor. A hose is communicated with the inner wall of the housing. The hose serves as a water flow channel. By virtue of the incompressibility of water, when the water pressure changes, the outer wall of the circular hole at the non-sleeved sleeve bulges, reflecting the water pressure and providing an adjustment signal. A sleeve is fixedly connected to the inner wall of the housing. One end of the lead screw penetrates and is threadedly connected to an annular sleeve plate. When there is a significant change in water pressure (either extremely high or extremely low), the motor operates to drive the lead screw to rotate, causing the annular sleeve plate to move to adjust the water pressure, further ensuring the water pressure balance of the entire water supply system and avoiding affecting the use due to water pressure problems. A circular hole is provided on the side of the sleeve. A cylinder is fixedly connected to the side of the sleeve. An electric push rod is fixedly connected to one side of the inner wall of the cylinder. The movable end of the electric push rod is fixedly connected to a push plate. When the water pressure increases and the bulging part of the hose contacts the elastic diaphragm, the electric push rod starts to push the push plate to adjust the water pressure and ensure the stability of the system. When the water pressure increases, the electric push rod starts to push the push plate to draw air backward to prevent harm caused by excessive water pressure. When the water pressure decreases, the push plate is pushed forward to compress the gas to increase the air pressure, ensuring that the water flow can be continuously supplied at a stable pressure. A communication hole is provided on the side of the cylinder. The provided communication hole communicates the cylinder with the inside of the housing, constructing an auxiliary channel for water pressure adjustment and creating conditions for the motor to intervene in adjustment in extreme cases where the water pressure exceeds the adjustment range of the electric push rod. An elastic diaphragm is fixedly connected to the inner wall of the cylinder. The top of the housing is communicated with the bottom of the water outlet pipe. The bottom of the housing is communicated with the top of the water inlet pipe. One end of the cylinder penetrates the housing and is fixedly connected to the housing.

[0008] The present invention provides a constant pressure energy-saving operation device for circulating water. It has the following beneficial effects:

[0009] 1. For this constant pressure energy-saving operation device for circulating water, the water vapor generated by the cooling of hot water is set to be drawn upward. When it encounters the rotating plate one and the rotating plate two, the water vapor adheres to them and cools into water droplets, which is conducive to the preliminary collection and recovery of water. The flow guide plate guides the water flow direction, and in cooperation with the folded plate, the water flow slides downward obliquely, effectively increasing the contact time between the water flow and the cold air and enhancing the possibility of heat exchange. The hose serves as a water flow channel. By virtue of the incompressibility of water, when the water pressure changes, the outer wall of the circular hole at the non-sleeved sleeve bulges, reflecting the water pressure and providing an adjustment signal. When the water pressure increases and the bulging part of the hose contacts the elastic diaphragm, the electric push rod starts to push the push plate to adjust the water pressure and ensure the stability of the system.

[0010] 2. A constant pressure energy-saving operation device for circulating water is provided with a condensing mechanism. Water vapor generated by hot water cooling is drawn upward, and when it meets rotating plate one and rotating plate two, the water vapor adheres to them and cools into water droplets, which is beneficial to preliminary water collection and recovery. The motor drives rotating rod one to rotate, and drives the rubber conveyor belt and rotating rod two by friction to rotate rotating plate two, so that the water droplets condensed on rotating plate one and rotating rod two can fall better. At the same time, it can also prevent poor ventilation, ensure that the entire cooling process can be carried out continuously and effectively, and ensure the cooling effect. When the remaining steam is discharged through the air outlet of the corrugated plate, it impacts the bottom surface of the corrugated plate made of elastic metal, causing tiny water droplets in the steam to gather, grow and slide down, reducing the water vapor being brought out, further recovering water, and improving the water recovery rate. The springs one and two on the top of the corrugated plate can buffer the impact of airflow, prevent the corrugated plate from being damaged, and ensure its normal operation. The outer sleeve of the spring one is provided with a folding hose one, and the outer sleeve of the spring two is provided with a folding hose two, which isolate water vapor, prevent the spring from rusting and losing elasticity, and ensure a lasting buffering effect.

[0011] 3. This kind of constant pressure energy-saving operation device for circulating water is provided with a slow flow mechanism. The guide plate guides the direction of water flow, and cooperates with the folding plate to allow the water flow to slide obliquely downward, effectively increasing the contact time between the water flow and the cold air and improving the possibility of heat exchange. The bending structure of the folding plate ensures that the water flow will not overflow outside the cooling tower during the sliding process. At the same time, its rectangular holes can allow cold air to pass through, realizing the intersection of gas and liquid. The guide plate guides the flow direction of the cold air airflow obliquely upward, so that the cold air can directly intersect with the water flow in the opposite direction, thereby improving the heat exchange efficiency and accelerating the heat transfer. After part of the water flow flows into the circular groove, due to the narrow channel of the circular groove, the water flow velocity slows down and the residence time is prolonged, allowing the cold air to have more time to fully absorb the heat of the water flow and enhance the heat exchange effect. When the cold air enters and exits the circular groove through the ventilation hole, the air flow velocity is accelerated and the pressure is reduced, which not only promotes the evaporation of water vapor, but also takes away more heat, further improving the cooling efficiency. The filter plate prevents the cold air from dispersing from below, prompts the cold air to move upward in a concentrated manner, and avoids the problem of uneven heat exchange or reduced efficiency caused by the dispersion of cold air.

[0012] 4. The constant-pressure energy-saving operation device for circulating water is provided with a constant-pressure mechanism. The hose serves as the water flow channel. By virtue of the incompressibility of water, when the water pressure changes, the wall of the round hole at the part not sleeved with the sleeve bulges outward, reflecting the water pressure and providing an adjustment signal. When the water pressure increases to cause the bulging part of the hose to contact the elastic diaphragm, the electric push rod starts to push the push plate to adjust the water pressure and ensure the stability of the system. When the water pressure increases, the electric push rod starts to push the push plate to evacuate air backward to prevent harm caused by excessive water pressure. When the water pressure decreases, it pushes the push plate forward to compress the gas to increase the air pressure and ensure that the water flow can be continuously supplied at a stable pressure. The opened communication holes connect the inside of the cylinder and the housing to construct an auxiliary channel for water pressure adjustment. In the extreme case where the water pressure exceeds the adjustment range of the electric push rod, it creates conditions for the motor to intervene in the adjustment. When there are extremely large or small changes in the water pressure, the motor rotates to drive the screw rod to rotate, causing the annular sleeve plate to move to adjust the water pressure, further ensuring the water pressure balance of the entire water supply system and avoiding affecting the use due to water pressure problems.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] For the first embodiment, please refer to Figures 1-4 , the present invention is a constant pressure and energy-saving operation device for circulating water, including a cooling tower main body 1.

The bottom of the constant pressure mechanism 8 is communicated with a water pipe 9. The bottom of the water pipe 9 is communicated with a circulating water pump 10. The water inlet of the circulating water pump 10 is communicated with an inlet pipe 11. One end of the inlet pipe 11 away from the circulating water pump 10 is communicated with a water tank 12. An air hole 13 is opened on the outer side of the cooling tower main body 1. The top of the water tank 12 is communicated with the bottom of the cooling tower main body 1;

[0024] The condensation mechanism 4 includes a connecting plate 41 and a first rotating rod 48. At the bottom of the connecting plate 41, a first folding hose 42 is fixedly connected. At the bottom of the connecting plate 41, a first spring 43 is fixedly connected. At the bottom of the first folding hose 42, a corrugated sheet 44 is fixedly connected. At the top of the corrugated sheet 44, a second folding hose 45 is fixedly connected. At the top of the corrugated sheet 44, a second spring 46 is fixedly connected. An air outlet hole 47 is formed at the top of the corrugated sheet 44. One end of the first rotating rod 48 is fixedly connected to the driving shaft of a motor 49. An annular baffle 410 is sleeved and rotatably connected to the first rotating rod 48. A rubber conveyor belt 411 is sleeved and drivingly connected to the first rotating rod 48. A second rotating rod 412 is rotatably connected to the inner side of the annular baffle 410. One end of the first rotating rod 48 penetrates and is fixedly connected to a first rotating plate 413. One end of the second rotating rod 412 penetrates and is fixedly connected to a second rotating plate 414. The side of the connecting plate 41 is fixedly connected to the inner wall of the cooling tower main body 1. The side of the corrugated sheet 44 is fixedly connected to the inner wall of the cooling tower main body 1. The top of the second folding hose 45 is fixedly connected to the inner wall of the cooling tower main body 1. The top of the second spring 46 is fixedly connected to the inner wall of the cooling tower main body 1. One end of the first rotating rod 48 penetrates the cooling tower main body 1 and is rotatably connected to the cooling tower main body 1. One side of the motor 49 is fixedly connected to one side of the cooling tower main body 1. One end of the second rotating rod 412 penetrates the cooling tower main body 1 and is rotatably connected to the cooling tower main body 1. The side of the annular baffle 410 away from the rubber conveyor belt 411 is fixedly connected to the inner wall of the cooling tower main body 1. The bottom of the first spring 43 is fixedly connected to the top of the corrugated sheet 44. When in use, the circulating water pump 10 starts, so that the water in the water tank 12 enters the constant pressure mechanism 8 through the water inlet pipe 11 and the through pipe 9. If the water pressure changes, the constant pressure mechanism 8 controls the water pressure to remain constant. The water flows out from the water outlet pipe 5 through the constant pressure mechanism 8 and enters the interior of the cooling tower main body 1, and is sprayed through the nozzle 6. The external cold air enters from the air holes 13, and the cold air is directly guided along the slow flow mechanism 7 to contact the water flow and the hot water, increasing the contact area between the two, making the heat exchange process more efficient. The sprayed water flow is in the slow flow mechanism 7, and the water flow is dispersed and converged multiple times, prolonging the residence time in the cooling tower, increasing the contact time with the cold air, improving the cooling effect, and thus saving energy consumption. Due to the direct heat transfer between the air and the water, the heat will be transferred from the water to the air, and due to the pressure difference between the water vapor surface and the air, evaporation will occur under the action of the pressure, taking away the latent heat of evaporation, thereby taking away the heat in the water and achieving the purpose of cooling. The top fan 3 rotates to generate an air flow, promoting the hot air after heat exchange to be extracted from the top, passing through the condensation mechanism 4. The water vapor in the hot air is cooled and liquefied when encountering the cold, and is cooled into water columns attached to the surface of the condensation mechanism 4. These water droplets converge into larger water droplets under the action of gravity and then fall back into the lower water tank 12, reducing water loss. After preliminary condensation, the remaining hot air containing a small amount of heat is discharged into the atmosphere through a special exhaust channel. The cooled water droplets fall back into the water tank 12. Finally, the water flow cooled by the cooling tower flows back into the water tank 12 again for recycling.The water vapor generated after the hot water is cooled by contacting the air is drawn upward. During the upward movement, it encounters the rotating plate 1 (413) and the rotating plate 2 (414), adheres to their surfaces, and is cooled into water droplets. The motor 49 starts, driving the first rotating rod 48 to rotate. A frictional force is generated between the rotation of the first rotating rod 48 and the rubber conveyor belt 411, driving the rubber conveyor belt 411 to drive, thereby causing the second rotating rod 412 to rotate and driving the rotating plate 2 (414) to rotate. The rotation of the rotating plate enables the water droplets to fall better, and at the same time prevents poor ventilation from affecting the cooling effect. When the remaining steam is discharged to the outside through the air outlet holes 47 on the surface of the corrugated sheet 44 and contacts the bottom surface of the corrugated sheet 44, since the corrugated sheet is made of elastic metal, when the steam impacts the bottom surface of the corrugated sheet 44, the elastic metal will deform. This deformation prompts the tiny water droplets in the steam to further aggregate and grow, making it easier to slide off the corrugated sheet, reducing the moisture carried out by the steam, and improving the water recovery rate. A first spring 43 and a second spring 46 are fixed to the top of the corrugated sheet 44 to buffer the impact of the air flow and prevent the corrugated sheet 44 from being damaged. A first folding hose 42 is sleeved outside the first spring 43, and a second folding hose 45 is sleeved outside the second spring 46 to prevent the water vapor from rusting the spring and losing its elasticity.,

[0025] For the second embodiment, please refer to Figures 1-8 , the present invention provides a constant-pressure energy-saving operation device for circulating water: the slow-flow mechanism 7 includes a folded plate 71, a diversion plate 73, and a wind guide plate 74. A rectangular hole 72 is opened on one side of the folded plate 71. A ventilation hole 75 is opened on the side of the wind guide plate 74 close to the folded plate 71. A circular groove 76 is opened at the top of the wind guide plate 74. A filter plate 77 is fixedly connected to the bottom of the wind guide plate 74. One side of the folded plate 71 is fixedly connected to the inner wall of the cooling tower main body 1. One side of the diversion plate 73 is fixedly connected to the inner wall of the cooling tower main body 1. One side of the wind guide plate 74 is fixedly connected to the inner wall of the cooling tower main body 1. The side surface of the filter plate 77 is fixedly connected to the inner wall of the cooling tower main body 1;

[0026] The constant pressure mechanism 8 includes a housing 81. A ventilation hole 82 is provided on the side of the housing 81. The bottom of the inner wall of the housing 81 is fixedly connected with a motor 83. The drive shaft of the motor 83 is fixedly connected with a lead screw 84. The inner wall of the housing 81 is communicated with a hose 85. The inner wall of the housing 81 is fixedly connected with a sleeve 86. One end of the lead screw 84 penetrates and is threadedly connected with an annular sleeve plate 87. A round hole 88 is provided on the side of the sleeve 86. A cylinder 89 is fixedly connected to the side of the sleeve 86. One side of the inner wall of the cylinder 89 is fixedly connected with an electric push rod 810. The movable end of the electric push rod 810 is fixedly connected with a push plate 811. A communication hole 812 is provided on the side of the cylinder 89. An elastic diaphragm 813 is fixedly connected to the inner wall of the cylinder 89. The top of the housing 81 is communicated with the bottom of the water outlet pipe 5. The bottom of the housing 81 is communicated with the top of the water pipe 9. One end of the cylinder 89 penetrates the housing 81 and is fixedly connected with the housing 81. During use, the water flow sprayed out through the nozzle 6 slides obliquely downward through the flow guide plate 73 and the folded plate 71, increasing the contact time with the cold air. The unique bent structure of the folded plate 71 enables the water flow not to flow out of the cooling tower during the sliding process. The cold air enters through the air hole 13 and passes through the rectangular holes on the folded plate 71, and is obliquely upward guided by the air guide plate 74 to flow, directly contacting the water flow. This reverse intersection mode of the air flow and the water flow improves the heat exchange efficiency. When the water flow falls on the surface of the air guide plate 74, part of the water flow enters the round groove 76, and the cold air contacts the water flow sliding in the round groove 76 through the ventilation hole 75, and heat exchange takes place inside the round groove 76. Due to the narrow channel of the round groove 76, the flow rate of the water flow in the round groove 76 slows down and the residence time prolongs, enabling the cold air to absorb the heat of the water flow more fully. Moreover, when the cold air passes through the ventilation hole 75, the air flow speed increases and the pressure decreases, further promoting the evaporation of the water vapor and taking away more heat. The filter plate 77 prevents the cold air from dispersing downward, making it move upward concentratedly, avoiding the problems of uneven heat exchange or reduced efficiency caused by the dispersion of the cold air. The water flow is transmitted through the hose 85. When the water pressure increases, due to the incompressibility of water, at the round hole 88 where the hose 85 is not sleeved by the sleeve 86, the water pressure will cause the pipe wall here to bulge outward.The bulging part will exactly come into contact with the adjacent elastic diaphragm 813. At this time, the electric push rod 810 is activated to push the push plate 811 to move backward for air extraction. The air extraction process reduces the air pressure in this area. According to the principle of the mutual correlation between gas and liquid pressure, the water pressure will decrease accordingly. At the same time, the decrease in air pressure will directly cause the deformation of the elastic diaphragm 813, playing a certain buffering role to avoid the impact on the system caused by sudden changes in water pressure. When the water pressure becomes smaller, the electric push rod 810 will push the push plate 811 to move forward. The forward thrust compresses the gas inside the device, increasing the air pressure, and then promoting the increase in the water pressure of the water flow to ensure that the water can be continuously supplied with a stable pressure. The communication hole 812 opened on the cylinder 89 connects the cylinder 89 with the inside of the housing 81. When the water pressure shows extreme situations of being too large or too small, beyond the adjustment range of the electric push rod, the motor 83 is started to further adjust the water pressure. The operation of the motor 83 drives the screw rod 84 to rotate. The screw rod 84 is in threaded cooperation with the annular sleeve plate 87, enabling the annular sleeve plate 87 to move towards the middle or towards both ends according to the rotation direction of the screw rod, so as to maintain the water pressure balance.

[0027] When the present invention is in operation, the circulating water pump 10 starts, causing the water in the water tank 12 to enter the constant pressure mechanism 8 through the water inlet pipe 11 and the water pipe 9. If the water pressure changes, the constant pressure mechanism 8 controls the water pressure to remain constant. The water flows out from the outlet pipe 5 through the constant pressure mechanism 8 and enters the inside of the cooling tower main body 1, and is sprayed through the nozzle 6. The external cold air enters from the air hole 13, and the cold air is directly guided along the slow flow mechanism 7 to contact the water flow and the hot water, increasing the contact area between the two, making the heat exchange process more efficient. The sprayed water flow is in the slow flow mechanism 7, and the water flow is dispersed and converged multiple times, prolonging the residence time in the cooling tower, increasing the contact time with the cold air, improving the cooling effect, and thus saving energy consumption. Due to the direct heat transfer between the air and the water, the heat will be transferred from the water to the air, and due to the pressure difference between the water vapor surface and the air, the evaporation phenomenon will occur under the action of the pressure, taking away the latent heat of evaporation, thereby taking away the heat in the water and achieving the purpose of cooling. The top fan 3 rotates to generate an air flow, prompting the hot air after heat exchange to be extracted from the top, passing through the condensation mechanism 4. The water vapor in the hot air is liquefied when it meets the cold, and is cooled into water columns attached to the surface of the condensation mechanism 4. These water droplets converge into larger water droplets under the action of gravity and then fall back into the lower water tank 12, reducing water loss. After preliminary condensation, the remaining hot air containing a small amount of heat is discharged into the atmosphere through a dedicated exhaust channel. The cooled water droplets fall back into the water tank 12. Finally, the water flow cooled by the cooling tower flows back into the water tank 12 for recycling. The water vapor generated after the hot water contacts the air and cools rises upward and is extracted. During the rising process, it meets the rotating plate one 413 and the rotating plate two 414, and adheres to the surface to be cooled into water droplets. The motor 49 starts, driving the rotating rod one 48 to rotate. The rotation of the rotating rod one 48 generates friction with the rubber conveyor belt 411, driving the rubber conveyor belt 411 to drive, so that the rotating rod two 412 rotates, driving the rotating plate two 414 to rotate. The rotation of the rotating plate makes the water droplets fall better, and at the same time prevents poor ventilation from affecting the cooling effect. When the remaining steam passes through the air holes 47 on the surface of the corrugated sheet 44 and is discharged to the outside, it contacts the bottom surface of the corrugated sheet 44. Since the corrugated sheet is made of elastic metal, when the steam impacts the bottom surface of the corrugated sheet 44, the elastic metal will deform. This deformation prompts the tiny water droplets in the steam to further aggregate and grow, making it easier to slide off the corrugated sheet, reducing the water carried out by the steam, and improving the water recovery rate. A spring one 43 and a spring two 46 are fixed at the top of the corrugated sheet 44 to buffer the impact of the air flow and prevent the corrugated sheet 44 from being damaged. A folding hose one 42 is sleeved outside the spring one 43, and a folding hose two 45 is sleeved outside the spring two 46 to prevent the water vapor from rusting the spring and losing its elasticity. The water flow sprayed through the nozzle 6 slides obliquely downward through the guide plate 73 and the folded plate 71, increasing the contact time with the cold air. The unique bending structure of the folded plate 71 makes the water flow not flow out of the cooling tower during the sliding process. The cold air enters from the air hole 13, passes through the rectangular holes on the folded plate 71, and is obliquely upward guided by the air guide plate 74 to flow directly into contact with the water flow.This reverse way of the air flow and water flow meeting improves the heat exchange efficiency. When the water flow falls onto the surface of the air guide plate 74, part of the water flow enters the circular groove 76, and the cold air contacts the water flow sliding in the circular groove 76 through the ventilation holes 75, and heat exchange takes place inside the circular groove 76. Due to the narrow channel of the circular groove 76, the flow rate of the water flow in the circular groove 76 slows down and the residence time is prolonged, enabling the cold air to absorb the heat of the water flow more fully. Moreover, when the cold air passes through the ventilation holes 75, the air flow speed increases and the pressure decreases, further promoting the evaporation of water vapor and taking away more heat. The filter plate 77 prevents the cold air from dispersing downward, making it move upward concentratedly, avoiding the problems of uneven heat exchange or reduced efficiency caused by the dispersion of cold air. The water flow is transmitted through the hose 85. When the water pressure increases, due to the incompressibility of water, at the circular hole 88 where the hose 85 is not sleeved by the sleeve 86, the water pressure will cause the pipe wall here to bulge outward. And the bulging part will just contact the adjacent elastic diaphragm 813. At this time, the electric push rod 810 starts and pushes the push plate 811 to move backward for air extraction. The air extraction process causes the air pressure in this area to decrease. According to the principle of the correlation between gas and liquid pressure, the water pressure will decrease accordingly. At the same time, the decrease in air pressure will directly cause the deformation of the elastic diaphragm 813, playing a certain buffering role to avoid the impact on the system caused by the sudden change of water pressure. When the water pressure becomes smaller, the electric push rod 810 will push the push plate 811 to move forward. The forward thrust compresses the gas inside the device, increasing the air pressure, and then promoting the increase of the water pressure of the water flow to ensure that the water can be continuously supplied with a stable pressure. The communication holes 812 opened on the cylinder 89 connect the cylinder 89 with the inside of the housing 81. When the water pressure appears in extreme situations of being too large or too small, beyond the adjustment range of the electric push rod, the motor 83 is started to further adjust the water pressure. The motor 83 rotates to drive the lead screw 84 to rotate. The lead screw 84 is in threaded cooperation with the annular sleeve plate 87, enabling the annular sleeve plate 87 to move toward the middle or toward both ends according to the rotation direction of the lead screw, so as to maintain the water pressure balance.,
