Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water turbine driven fillerless spray cooling tower. Background Technology

[0002] As a core component of industrial circulating water cooling systems, turbine-driven fillerless spray cooling towers utilize water turbines instead of traditional electric motor-driven fans to achieve efficient energy use. They also employ fillerless spray technology to enhance heat exchange efficiency. These cooling towers are widely used in power, chemical, and other fields, and their structural optimization is of great significance for reducing operation and maintenance costs and improving system reliability.

[0003] In the existing technology, the nozzles of traditional spray cooling towers are mostly installed on the water distribution pipe by bolt fixing or threaded connection. Such structures require tools to remove fasteners to separate the nozzles. In addition, the water distribution pipes are usually densely arranged in the narrow space inside the cooling tower. The filter components are mostly designed by integral welding or flange bolts. Cleaning requires disassembling the entire inlet pipe, making the operation process cumbersome.

[0004] However, the above structure has significant drawbacks. Its nozzle maintenance efficiency is low. When poor water quality causes nozzle blockage, operators need to carry tools into the narrow casing and disassemble multiple bolts one by one in the confined space. The cleaning process is time-consuming, and the tools are inconvenient to operate in the narrow space, posing a safety hazard. Frequent disassembly will also accelerate thread wear, further increasing maintenance difficulty and downtime, thus restricting the continuous operation capability of the cooling tower. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water turbine-driven fillerless spray cooling tower, which aims to improve the problem of low nozzle maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water turbine-driven fillerless spray cooling tower, including a casing, a frame fixedly connected to the lower surface of the casing, a water inlet pipe fixed to the inner wall of the frame, a filter pipe connected to one end of the water inlet pipe via a flange, a filter assembly disposed inside the filter pipe, a connecting pipe fixedly connected to the inner wall of the casing, a water distribution pipe fixedly connected to the outer wall of the connecting pipe, a nozzle disposed inside the water distribution pipe, and a connecting assembly disposed on the outer wall of the nozzle;

[0007] The connecting assembly includes an upper clamping ring and a lower clamping ring. The inner wall of the upper clamping ring is fixedly connected to the outer wall of the nozzle, and the outer wall of the lower clamping ring is rotatably connected to the outer wall of the upper clamping ring. The upper clamping ring is sleeved on the outer wall of the water distribution pipe, and the lower clamping ring is sleeved on the outer wall of the water distribution pipe. A slot is provided on the outer wall of the upper clamping ring, and a locking block is slidably connected to the inner wall of the lower clamping ring. The locking block engages with the slot, and a sliding button is fixedly connected to the outer wall of the locking block.

[0008] Furthermore, the filter assembly includes a filter screen disposed inside a filter tube, a connecting flange fixedly connected to one end of the filter tube, and a tube cap rotatably connected to the lower surface of the connecting flange.

[0009] Furthermore, a nut is provided on the upper surface of the connecting flange 21, and a bolt is threadedly connected inside the pipe cover, with the bolt and nut being threadedly connected.

[0010] Furthermore, a spring is provided inside the lower clamping ring, with one end of the spring fixedly connected to the outer wall of the clamping block and the other end of the spring fixedly connected to the inner wall of the lower clamping ring.

[0011] Furthermore, a hydraulic turbine is installed inside the casing, and the water inlet end of the hydraulic turbine is fixedly connected to the other end of the water inlet pipe.

[0012] Furthermore, the outlet end of the hydraulic turbine is fixedly connected to one end of the connecting pipe, and the output end of the hydraulic turbine is fixedly connected to a drive shaft.

[0013] Furthermore, a fan is fixedly connected to one end of the drive shaft, and an air inlet is provided on the outer wall of the housing.

[0014] Furthermore, an exhaust vent is provided on the upper surface of the housing, and a water outlet is provided on the lower surface of the housing.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through the design of the connecting components, the operator can quickly disassemble the nozzle without tools. Simply push the sliding button with one hand to disengage the locking block from the slot, and then rotate the lower clamping ring to release the lock on the water distribution pipe. The operation is simple and significantly simplifies the cleaning process when the nozzle is clogged. The maintenance time is much shorter than that of the traditional bolt fixing method, and it is especially suitable for operation in narrow spaces.

[0017] 2. In this utility model, the filter component adopts a split quick-opening structure to achieve efficient maintenance of the filter screen. When the filter screen needs to be cleaned, the operator only needs to loosen the bolts to detach the pipe cover from the connecting flange, and then directly pull out the filter screen for rinsing. There is no need to disassemble the pipe flange throughout the process. This design optimizes the pain point of traditional cooling tower filter screen cleaning requiring pipe disassembly, greatly shortens maintenance time, and enables the system to operate continuously and stably.

[0026] Reference Figure 1 - Figure 5This utility model provides an embodiment of a water turbine-driven fillerless spray cooling tower, including a casing 1 providing stable support. A frame 2 is fixedly connected to the lower surface of the casing 1. A water inlet pipe 8 is fixed to the inner wall of the frame 2 as the main channel for cooling water to enter the equipment. One end of the water inlet pipe 8 is connected to a filter pipe 19 via a flange. The filter pipe 19 is equipped with a filter assembly to intercept impurities in the water and prevent the spray nozzles 18 from clogging.

A water distribution pipe 11 is fixedly connected to the outer wall of the connecting pipe 9 to evenly distribute the water flow to the spray nozzle array 18. The water distribution pipe 11 is equipped with a filter assembly inside. A nozzle 18 is provided to achieve efficient atomization of cooling water. A connecting assembly is provided on the outer wall of the nozzle 18, including an upper clamping ring 12 and a lower clamping ring 13. The inner wall of the upper clamping ring 12 is fixedly connected to the outer wall of the nozzle 18 to ensure synchronous movement of the nozzle 18 and the clamping ring. The outer wall of the lower clamping ring 13 is rotatably connected to the outer wall of the upper clamping ring 12. The upper clamping ring 12 is fitted onto the outer wall of the water distribution pipe 11, and the lower clamping ring 13 is fitted onto the outer wall of the water distribution pipe 11. A groove 14 is provided on the outer wall of the upper clamping ring 12, and a locking block 15 is slidably connected to the inner wall of the lower clamping ring 13. The locking block 15 engages with the groove 14 to ensure a secure connection of the nozzle 18 during operation. A sliding button 16 is fixedly connected to the outer wall of the locking block 15. The filter assembly includes a filter screen 20, which is located inside the filter tube 19. A connecting flange 21 is fixedly connected to one end of the filter tube 19. A tube cap 22 is rotatably connected to the lower surface of the connecting flange 21 for easy replacement of the internal filter screen 20. A nut 23 is provided on the upper surface of the connecting flange 21. A bolt 24 is threadedly connected inside the tube cap 22, and the bolt 24 is threadedly connected to the nut 23. A spring 17 is provided inside the lower clamping ring 13. One end of the spring 17 is fixedly connected to the outer wall of the locking block 15, and the other end of the spring 17 is fixedly connected to the inner wall of the lower clamping ring 13. Inside the housing 1... The unit is equipped with a water turbine 6 that uses the kinetic energy of water to drive a fan 5. The water inlet of the water turbine 6 is fixedly connected to the other end of the water inlet pipe 8, directly utilizing the energy of the filtered water flow. The water outlet of the water turbine 6 is fixedly connected to one end of the connecting pipe 9, converting the remaining water pressure into spray power. The output end of the water turbine 6 is fixedly connected to a drive shaft 7, and one end of the drive shaft 7 is fixedly connected to a fan 5 to generate ventilation airflow. An air inlet 3 is opened on the outer wall of the casing 1 as a channel for hot air to rise and be discharged. An exhaust port 4 is opened on the upper surface of the casing 1, and a water outlet 10 is set on the lower surface of the casing 1 to collect the cooled water flow for recycling.

[0027] Working Principle: When the water turbine is used to drive the fillerless spray cooling tower, the device is fixed by the frame 2. Circulating water flows into the equipment through the inlet pipe 8, first entering the filter pipe 19. The filter screen 20 inside the filter pipe filters impurities from the water flow, ensuring clean water quality. The filtered water enters the inlet end of the water turbine 6 through the inlet pipe 8. The water flow impacts the turbine blades, driving the water turbine 6 to rotate. The rotation of the water turbine 6 is transmitted to the fan 5 through the drive shaft 7, causing the fan 5 to rotate at high speed. At the same time, the outlet end of the water turbine 6 delivers pressurized water to the connecting pipe 9 and distributes it to each water distribution pipe 11. The water flow is atomized and sprayed out through the nozzles 18 inside the water distribution pipe 11, forming a fine mist. Outside air is drawn into the tower through the air inlet 3 on the side wall of the casing 1 by the fan 5. As it flows upward, it comes into full contact with the falling water mist, and the water, after heat exchange and cooling, is collected at the outlet 10 at the bottom of the casing 1 and discharged. The humid air, after absorbing heat, is discharged to the atmosphere through the exhaust vent 4 at the top. If the nozzle 18 is blocked, the operator pushes the slide button 16 with one hand to compress the spring 17, so that the locking block 15 is disengaged from the slot 14 of the upper clamping ring 12. Then, the lower clamping ring 13 is rotated to release the clamp on the water distribution pipe 11, and the nozzle 18 can be disassembled for cleaning. The filter screen 20 is cleaned by loosening the bolt 24 to release the nut 23, so that the pipe cover 22 is disengaged from the connecting flange 21, and the filter screen 20 can be directly pulled out for rinsing.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
