Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, and more particularly to a cooling tower with a pre-cooling device. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus dissipating the waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] Traditional cooling towers often fail to provide adequate cooling in high-temperature environments or under high loads, leading to increased energy consumption and reduced equipment efficiency. To improve cooling performance, pre-cooling devices are often added. However, adding pre-cooling devices to existing cooling towers requires increasing the number of motors or water pumps, potentially causing the pre-cooling devices themselves to consume more energy, thus offsetting the overall energy-saving effect of the cooling tower to some extent.

[0004] To address this, we designed a cooling tower with a pre-cooling device. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by providing a cooling tower with a pre-cooling device.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figure 1-3 A cooling tower with a pre-cooling device includes a cylindrical body 1. A water collection tank 6 is provided below the cylindrical body 1 to collect the treated condensate. Multiple support legs 2 are fixedly connected to the bottom of the water collection tank 6 to provide stable support for the cooling tower. An air inlet pipe 3 is fixedly connected to the side wall of the cylindrical body 1. The air inlet pipe 3 is composed of air pipes connected to the side wall of the cylindrical body 1 at both ends. The two air pipes intersect and merge into one air pipe at one end near the air inlet.

[0022] A spray pipe 5 is installed at the top of the air inlet pipe 3 near the air inlet. The bottom of the spray pipe 5 is full of holes for condensate to flow out from the spray pipe 5, thereby pre-cooling the absorbed hot air. A dustproof net 10 is installed at the inlet of the air inlet pipe 3 to prevent dust from entering the cooling tower. A baffle plate 20 is installed at the bottom of the inner wall of the air inlet pipe 3 near the inlet to prevent condensate from flowing out from the inlet of the air inlet pipe 3. A condensate outlet pipe 26 is installed at the bottom of the air inlet pipe 3.

[0023] A return water pipe 4 is fixedly connected to the side wall of the cylinder 1. The lower end of the return water pipe 4 passes through the air inlet pipe 3 and is fixedly connected to the upper end of the spray pipe 5. A motor 11 is installed at the bottom of the cylinder 1. A roller 8 is installed at the central axis of the cylinder 1. The roller 8 is fixedly connected to the output end of the motor 11. A fan 22 is fixedly connected to the side wall of the roller 8 near the upper end. A baffle 19 is installed outside the fan 22. A water spray plate 18 is fixedly connected to the bottom of the baffle 19. The side wall of the water spray plate 18 is fixedly connected to the inner wall of the cylinder 1. A water collector 24 is fixedly connected to the top of the cylinder 1. The water spray plate 18 is located at the upper end of the connection between the air inlet pipe 3 and the cylinder 1. The motor 11 drives the roller 8 to rotate, thereby causing the fan 22 to rotate and generating an upward airflow to promote heat exchange between the air and the treated water. Under the action of the water collector 24 and the water spray plate 18, the heat is discharged to the outside while the condensate is collected and falls into the water collection tank 6 below.

[0024] The upper end of the roller 8 is rotatably connected to a water distribution pipe 25. Three nozzles 23 are fixedly connected to the side wall of the water distribution pipe 25. A treatment water inlet pipe 21 is fixedly connected to the side wall of the water distribution pipe 25. The end of the treatment water inlet pipe 21 away from the water distribution pipe 25 passes through and is fixedly connected to the side wall of the cylinder 1. The rotation of the roller 8 does not cause the water distribution pipe 25 to rotate. The roller 8 provides vertical support for the water distribution pipe 25. The treatment water enters the water distribution pipe 25 from the treatment water inlet pipe 21, and is then sprayed into the cooling tower through the nozzles 23.

[0025] The lower end of the roller 8 passes through and is rotatably connected to the bottom plate of the water collection tank 6. A first bevel gear 12 is fixedly connected to the side wall of the end of the roller 8 extending out of the water collection tank 6. A first fixed rod 28 is fixedly connected to the lower end face of the bottom plate of the water collection tank 6. A second bevel gear 13 and a second flat gear 14 are respectively provided on the two side walls of the first fixed rod 28. The second bevel gear 13 and the second flat gear 14 are fixedly connected by a round rod, which passes through and is rotatably connected to the first fixed rod 28. A second fixed rod 29 is fixedly connected to the lower end face of the bottom of the water collection tank 6. A first flat gear 9 is rotatably connected to the side wall of the second fixed rod 29 near the lower end. The first flat gear 9 and the second flat gear 14 are on the same plane and cooperate with each other. The first bevel gear 12 and the second bevel gear 13 cooperate with each other. The motor 11 drives the roller 8 and the first bevel gear 12 to rotate, thereby driving the second bevel gear 13 to rotate. The second bevel gear 13 and the second flat gear 14 rotate synchronously. The second flat gear 14 drives the first flat gear 9 to rotate.

[0026] The water collection tank 6 has a groove 27, and the cylinder 1 has a water collection box 7 inside. The external dimensions of the water collection box are the same as the inner diameter of the groove 27. The bottom of the water collection box 7 is fixedly connected to a lifting rod 17, and the side wall of the first flat gear 9 is fixedly connected to a lifting mechanism that pushes the lifting rod 17 to move up and down.

[0027] The lifting mechanism includes a connecting rod 16 rotatably connected to the bottom side wall of the lifting rod 17. A rotating rod 15 is rotatably connected to the end of the connecting rod 16 away from the lifting rod 17. A round rod passes through the side wall of the rotating rod 15 away from the connecting rod 16 and is fixedly connected to the side wall of the first flat gear 9. The round rod is rotatably connected to the second fixed rod 29. The first flat gear 9 causes the rotating rod 15 to rotate. The rotating rod 15 pushes the lifting rod 17 up and down through the connecting rod 16. Thus, the lifting rod 17 drives the water collection box 7 to move up and down. The up and down movement of the water collection box 7 continuously transports the condensate in the water collection tank 6 to the spray pipe 5 through the return water pipe 4.

[0028] In use, the operator delivers treated water into the cooling tower through the treated water inlet pipe 21. The treated water then enters the nozzle 23 through the water distribution pipe 25 and is sprayed out. After starting the motor 11, the motor 11 drives the roller 8 to rotate, which in turn drives the fan 22 to rotate, drawing in outside air from the air inlet pipe 3 for heat exchange with the treated water. After heat exchange, the treated water falls through the water collector 24 and the water spray plate 18 and finally collects in the water collection pool 6. The first bevel gear 12 drives the second bevel gear 13 to rotate, which in turn drives the second flat gear 14 to rotate. The second flat gear 14 carries... The first spur gear 9 rotates, causing the rotating rod 15 to rotate. The rotating rod 15 pushes the lifting rod 17 up and down through the connecting rod 16. The lifting rod 17 pushes the water collection box 7 up and down. When the water collection box 7 falls into the groove 27, the condensate accumulated in the water collection pool 6 enters the water collection box 7. The water collection box 7 then pushes the condensate to the inlet of the return water pipe 4, and pushes the condensate through the return water pipe 4 into the spray pipe 5. The condensate then drips from the lower hole of the spray pipe 5 into the air inlet pipe 3 to pre-cool the hot air entering the air inlet pipe 3. Finally, the condensate is discharged from the condensate outlet pipe 26.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
