Technical Field

[0001] This utility model relates to the field of counter-flow cooling tower technology, specifically a water distribution device for a counter-flow cooling tower. Background Technology

[0002] A counter-flow cooling tower is a device that cools water by having water flow vertically downwards within the tower, with the airflow direction opposite to the water flow direction. The water exchanges heat and mass with the flowing air inside, causing the water temperature to drop. Cooling towers are classified into counter-flow and cross-flow types.

[0003] The existing Chinese utility model patent with publication number CN211291092 U provides a counter-flow cooling tower energy-saving water distribution device, which includes a motor installed at the top of the cooling tower and a fan blade connected to the motor and installed at the top of the cooling tower. A water distribution pipe is installed at the lower end of the fan blade, and water spray holes are evenly distributed on the water distribution pipe. The motor drives the fan blade to rotate, blowing water through the water distribution pipe, so that the water is sprayed in all directions with the wind direction to achieve a cooling effect. With the water distribution device of this utility model, the water distribution pipe can evenly spray water under the rotation of the fan blade, thereby improving the cooling efficiency of the cooling tower.

[0004] The existing cooling tower sprays water onto the packing plate through a water distribution device. The water distribution device has multiple nozzles. When a nozzle is damaged, the device needs to be suspended for maintenance by maintenance personnel. Moreover, the nozzle replacement time is slow, which affects the use of the device. The nozzles are fixedly installed, and the water distribution cannot be adjusted according to the temperature and humidity of the packing area, resulting in energy waste.

[0030] Example 1:

[0031] Please refer to Figure 1-4 , a water distribution device for a countercurrent cooling tower, including;

[0032] The cooling tower body 1, the front end of the cooling tower body 1 is fixedly connected with a water pump 6, and the upper end of the water pump 6 is fixedly installed with a conveying pipeline 7;

[0033] The water delivery pipe 8 is fixedly installed at the rear end of the conveying pipeline 7, and a connecting pipe 9 is fixedly installed inside the water delivery pipe 8. A rotating pipe 10 is inserted and connected inside the connecting pipe 9. The outer end of the rotating pipe 10 is fixedly connected with a connecting ring 11. The upper end of the connecting ring 11 is fixedly installed with a fixing block 12, and the upper end of the fixing block 12 is fixedly connected with a rotating gear 13. The upper end of the rotating gear 13 is meshed and connected with a driving gear 14.

[0034] The water delivery pipe 8 is in the shape of a "mouth", an installation hole is fixedly opened at the lower end of the water delivery pipe 8. The connecting pipe 9 is symmetrically installed before and after with the water delivery pipe 8 as the central base inside the water delivery pipe 8. The bottom surface of the fixing block 12 is fixedly installed above the water delivery pipe 8.

[0035] In this embodiment, the water pump 6 is connected to the conveying pipeline 7. The water pump 6 pumps water from the water collecting tank and transports it to the annular water delivery pipe 8 (mouth-shaped structure) through the conveying pipeline 7. The annular water delivery pipe 8 is evenly distributed with a plurality of nozzles 22 to ensure that the cooling water covers the entire packing layer. The connecting pipe 9 is used as a transition connecting part to penetrate the water delivery pipe 8 and the rotating pipe 10 to ensure continuous water flow. The rotating pipe 10 is flexibly connected to the connecting pipe 9 through the connecting ring 11 to ensure that there is no water leakage during rotation. The fixing block 12 is fixed to the rotating gear 13 to prevent slipping. The rotating gear 13 is meshed with the driving gear 14. The driving gear 14 is driven by a motor controlled by a PLC to drive the rotating gear 13 to rotate.

[0036] The drain pipe 15 is fixedly installed at the lower end of the water delivery pipe 8, and limiting grooves 16 are fixedly installed on both sides of the drain pipe 15. A first permanent magnet 17 is fixedly installed inside the limiting grooves 16;

[0037] The connecting pipe 18 is inserted and connected inside the drain pipe 15, and a support plate 19 is fixedly installed on the outer side of the connecting pipe 18. Insertion blocks 20 are fixedly installed on both sides of the support plate 19, and a second permanent magnet 21 is fixedly installed at the upper end of the insertion blocks 20.

[0038] The drain pipe 15 is fixedly connected to the water delivery pipe 8 through the installation hole. The top surfaces of the limiting grooves 16 and the first permanent magnet 17 are fitted with the bottom surface of the water delivery pipe 8. The insertion blocks 20 are inserted and connected with the limiting grooves 16. The first permanent magnet 17 and the second permanent magnet 21 are fixedly connected.

[0039] The nozzle 22 is fixedly connected to the lower end of the connecting pipe 18, and an ultrasonic vibrator 23 is fixedly installed inside the nozzle 22.

[0040] In this embodiment, after the insertion block 20 (T-shaped cross section) and the limiting groove 16 (matching groove) are inserted, they are laterally locked by the extension plate of the support plate 19 to prevent loosening caused by water flow impact. The first permanent magnet 17 (circular arrangement) and the second permanent magnet 21 are installed at the top of the connecting pipe 18. When the two are close, they automatically align and adsorb, achieving a connection in seconds, which facilitates quick replacement of the nozzle 22. Extension plates are added to both sides of the support plate 19, and the insertion block 20 is fixed and used in conjunction with the limiting groove 16 by the extension plates. The ultrasonic vibrator 23 is integrated inside the nozzle 22, and the high-frequency vibration removes scale / algae, reducing the frequency of manual cleaning.

[0041] Example 2:

[0042] Please see Figure 1 This embodiment provides a technical solution based on Embodiment 1:

[0043] Air inlet 2 is fixedly installed around the lower end of the cooling tower body 1;

[0044] Water collector 3 is fixedly installed inside the cooling tower body 1, and a fan 4 is fixedly installed on the upper end of the water collector 3, and solar panels 5 are fixedly installed on both sides of the fan 4.

[0045] A protective net is fixedly installed at the upper end of the air inlet 2. The solar panel 5 is symmetrically installed on the top of the cooling tower body 1 with the cooling tower body 1 as the central base. The solar panel 5 has an inclined structure.

[0046] In this embodiment, cold air enters the cooling tower body 1 through the air inlet 2 and comes into countercurrent contact with the falling water film to improve cooling efficiency. The fan 4 draws the hot and humid air upward, and after the water droplets are intercepted by the water collector 3, the air is discharged to reduce water consumption. The fan 4 also discharges the hot air inside the cooling tower body 1. The tilted solar panel 5 converts light energy into electrical energy, which is preferentially used to power the water pump 6, the fan 4, and the PLC controller. When the power supply is insufficient, the power supply switches to the grid. The solar panel 5 is equipped with an energy storage battery to store electricity on sunny days for use on cloudy days. The water pump 6 draws water from the water collection tank and delivers it to the spray system through the conveying pipe 7.

[0047] The working principle of this utility model is as follows: Water pump 6 is started, pumping water from the water collection tank of the cooling tower body 1 into the water supply pipe 8 through the delivery pipe 7. The water flows through the connecting pipe 9 into the rotating pipe 10, and finally sprays through the nozzle 22. An IoT sensor, model LoRa, monitors the tower temperature in real time and adjusts the water distribution mode accordingly. NB-IoT transmits data to the PLC controller. The PLC starts and drives gear 14, which in turn drives the meshing rotating gear 13 to rotate. This causes the fixing block 12 to adjust the angle of the rotating tube 10. The rotating tube 10 and the water supply pipe 8 are flexibly connected through the connecting ring 11 to ensure sealing during rotation. The nozzle 22 is connected to the drain pipe 15 through the connecting pipe 18. It is fixed by adsorption using the first permanent magnet 17 (at the end of the connecting pipe 18) and the second permanent magnet 21 (at the bottom of the water supply pipe 8). The nozzle 22 and the connecting pipe 18 are fixed by a combination of thread and magnetic attraction. When replacing, it can be disassembled by rotating counterclockwise. The insertion block 20 on the support plate 19 is inserted into the limiting groove 16. The concave and convex locking enhances the connection stability and prevents the water flow from causing it to detach.
