TECHNICAL FIELD

[0001] The patent relates to the field of cooling tower structure design, and specifically relates to an energy-saving cooling tower. BACKGROUND

[0002] At present, with the continuous development of China's economy and industry, environmental problems have gradually become one of the hot issues that people urgently need to solve. The structure design and function improvement of the cooling tower, as an important part of the environmental problem of sewage treatment, have gradually attracted people's attention. In addition to the improvement of the design of the cooling tower in simplifying the structure, the energy saving and environmental protection, the improvement of the cooling efficiency and other aspects are also involved. By continuously improving the performance of the cooling tower, gradually improving the cooling efficiency of the water source, and reducing the overall power consumption of the cooling tower.

[0003] The patent CN201720221025 provides a cooling tower device, which is used as a standby device when one of the multiple cooling towers is being repaired, to avoid factory downtime and improve the practical efficiency of the cooling tower. However, this patent only considers the production efficiency problem during maintenance and does not consider the production efficiency problem during the daily use of the cooling tower, which cannot fundamentally improve the working performance of the cooling tower.

[0004] The patent CN201620758202 provides a cooling tower with an online descaling device for the water distributor, which is used to clean the scale on the water distributor in real time during the operation of the cooling tower, to improve the service life of the cooling tower. However, this patent mainly improves the cleaning of the water distributor and does not involve the optimization of the overall efficiency of the cooling tower. At the same time, the descaling agent will cause chemical pollution to the water in the cooling tower, which will affect the overall operation of the cooling tower.

[0005] Therefore, in view of the problems existing in the design and improvement of the cooling tower at present, an energy-saving cooling tower is urgently needed, which improves the overall cooling efficiency of the cooling tower by improving the structure of the water distributor, thereby achieving the effect of energy saving.

[0009] Preferably, a flow divider 11 is mounted directly above the nozzle 10; the flow divider 11 has an inverted cone structure.

[0010] Preferably, when the nozzle 10 sprays upward water flow, the diverter 11 located directly above the nozzle 10 cuts off the upward water flow, causing the upward water flow to flow downward in a circular shower head shape.

[0011] Preferably, the diverter 11 is equipped with support frames on both sides; the support frames support the diverter 11 by being fixed to both sides of a single nozzle.

[0014] Preferably, the cooling tower further includes a temperature monitoring device and a pressure monitoring device.

[0015] Preferably, the air inlet window 7 of the cooling tower can control the airflow speed inside the cooling tower by intelligently adjusting the opening angle and opening size.

[0016] The present invention has the following beneficial effects:

[0017] (1) The present invention sprays water vertically upwards in the direction of the spray water distributor and disperses it when it encounters the cone-shaped structure of the distributor, thereby refining the water into particles, increasing the contact area between the water flow and the air, accelerating the evaporation rate of the water flow and thus accelerating the cooling efficiency of the water flow.

[0018] (2) By installing a diverter above the nozzle, the rising water flow begins to fall before reaching its highest point and its speed is 0, thus slowing down the falling speed of the water flow. Through low-pressure and low-speed water flow control, the spray speed is slowed down, the particle size of the water mist when it falls is reduced, and the contact time between the water flow and the air is increased, thereby accelerating the cooling efficiency of the water flow.

[0019] (3) The present invention eliminates the related devices of the packing part, simplifies the overall structure of the cooling tower, and reduces production costs. Attached Figure Description

[0024] In one embodiment, the cooling tower water distributor 5 is a spray-type water distributor; the spray direction of the spray-type water distributor is vertically upward, and the spray-type water distributor is installed at the lower end of the fan inside the cooling tower; the spray-type water distributor has nozzles 10 evenly distributed on it, and a diverter 11 is mounted directly above the nozzles 10; the diverter 11 has an inverted cone structure, and support frames are installed on both sides of the diverter 11; the support frames support the diverter 11 by fixing it to both sides of a single nozzle, and when the nozzle 10 sprays upward water flow, the diverter 11 located directly above the nozzle 10 cuts off the upward water flow, causing the upward water flow to flow downward in a circular shower head shape.

[0025] In a preferred embodiment, the cooling tower water distributor 5 can also be a pipe-type water distributor or a drip-type water distributor; the cooling tower can be a circular cooling tower or a square cross-flow cooling tower, and the cooling tower adopts a counter-flow type, which forms a negative pressure by flowing water vapor from the high-pressure area to the low-pressure area in the cooling tower, thereby removing the heat in the water flow.

[0026] In one embodiment, the cooling tower is a fillerless direct-injection cooling tower.

[0027] In a preferred embodiment, the fillerless direct-injection cooling tower removes the original filler device, avoiding secondary pollution of the water source caused by bacteria and moss growth due to the filler being soaked in a closed environment for a long time. At the same time, due to the improvement of the water spraying method in this invention, the cooling efficiency of the water flow is improved. Therefore, the filler cooling step is eliminated, the overall design structure of the cooling tower is simplified, and the manufacturing cost of the cooling tower is reduced.

[0028] In one embodiment, the cooling tower further includes a spray pump 10; the spray pump 10 is connected to the cooling tower water distributor 5 via a pipeline; the spray pump 10 applies high pressure to the water source stored in the water-passing tray 5, and uses high pressure driving force to transport the water source to the cooling tower water distributor 5 for spraying.

[0029] In one embodiment, the cooling tower further includes a temperature monitoring device and a pressure monitoring device. Specifically, these are used to monitor the water temperature and air pressure within the cooling tower in real time, thereby adjusting the temperature inside the cooling tower according to changes in outdoor temperature, improving the practical performance of the cooling tower, and preventing safety hazards caused by excessive pressure inside the cooling tower.

[0030] In one embodiment, the air inlet 7 of the cooling tower can control the airflow speed inside the cooling tower by intelligently adjusting the opening angle and the opening size.

[0031] In a preferred embodiment, the intelligent adjustment is achieved by setting a small drive motor on the outside of the opening and closing shaft of the air inlet 7. The rotation of the small drive motor drives the rotation of the opening and closing shaft, thereby causing the air inlet 7 to open and close. The small drive motor is equipped with a wireless Bluetooth sensor, which is connected to a mobile APP. The mobile APP can communicate with the wireless Bluetooth sensor of the small drive motor through its Bluetooth module to realize the operation control of the small drive motor.

[0032] The specific working principle is as follows: water enters through the inlet 8 and is fed into the spray pump 10. The spray pump 10 uses high pressure to force the water to the cooling tower water distributor 5. The water is sprayed evenly through the nozzles 10 on the cooling tower water distributor 5 to form an upward water flow. The upward water flow is intercepted and descended by the distributor 11 and exchanges heat with the air. The fan 4 is driven by the cooling tower motor 3. The fan 4 rotates to draw out the hot air from the top of the cooling tower. At the same time, dry cold air enters the tower through the cooling tower air inlet 7 at the bottom of the cooling tower, forming a counter-current air circulation. The cooling water drips into the water-passing tray 6 and is discharged through the outlet 9, completing one cooling water circulation operation.
