Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to an intelligent control direct-connected energy-saving and environmentally friendly cooling tower. Background Art

[0002] In industrial production, water is used to cool equipment. Many years ago, environmental protection required that the water used for cooling equipment must also be recycled and cannot be directly discharged. A cooling tower is a device that can recycle cooling water. The high-temperature water of the cooling equipment enters the cooling tower, and after being cooled by the water distribution device and the water-spraying filler, it enters the cooling water pool. The water in the cooling water pool then provides a water source for cooling the equipment, thus forming a water cycle. However, there is a problem with the cooling tower in the prior art, that is, the high-temperature water stays in the tower for too short a time, causing the high-temperature water to fall into the low-temperature water pool before reaching the ideal temperature, resulting in the subsequent cooling effect on the equipment being affected. Therefore, we need to improve the internal structure of the cooling tower so that the high-temperature water can stay in the tower for a longer time and the water falling into the low-temperature pool reaches the ideal temperature. Utility Model Content

[0003] Problem to be solved: Prolong the time that high-temperature water stays in the cooling tower so that the water falling into the low-temperature pool reaches the ideal temperature.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent controlled direct-connected energy-saving and environmentally friendly cooling water tower, comprising a cooling water tower, the cooling water tower is provided with a water supply pipe, the outlet end of the water supply pipe is connected to a water distribution device, a fan unit is provided on the top of the cooling water tower, a cooling water pool is provided at the bottom of the cooling water tower, a water collector is provided between the water distribution device and the fan unit, and a water sprinkling filler is provided between the water distribution device and the cooling water pool; the water sprinkling filler comprises a plurality of S-shaped through hole layers and a plurality of folded wave through hole layers, the plurality of S-shaped through hole layers and the plurality of folded wave through hole layers are cross-stacked and connected, the S-shaped through hole layer comprises a plurality of S-shaped through holes, and the folded wave through hole layer comprises a plurality of folded wave holes; the water collector comprises at least one water-blocking layer, the water-blocking layer comprises a plurality of S-shaped condensate pipes; a plurality of nozzles are provided on the water distribution device; the water supply pipe and the cooling water pool are both provided with signal thermometers, and the signal thermometer and the fan unit are both connected to the intelligent controller.

[0006] Preferably, the water spray filler is fixed in the cooling tower through a filler bracket.

[0007] Preferably, a guide plate is provided below the filler support.

[0008] Preferably, a sound-absorbing layer is provided in the cooling tower, and the sound-absorbing layer is located in the area above the cooling water pool.

[0009] Preferably, the side wall of the cooling tower is provided with louvers, and the louvers are located in the area between the cooling water pool and the water spray filler.

[0010] Preferably, the fan unit includes an air duct, an axial flow fan is provided in the air duct, the bottom end of the axial flow fan is directly connected to a synchronous motor, a lightning protection device is provided at the top end of the air duct, and the synchronous motor is connected to the intelligent controller.

[0011] Compared with the existing technology, the utility model provides an intelligent control direct-connected energy-saving and environmentally friendly cooling tower, which has the following beneficial effects:

[0012] 1. The water distribution device is equipped with several nozzles that spray water upwards, so that the high-temperature water falls evenly into the water filling;

[0013] 2. The water-spraying filler is changed from vertical through-holes to shaped through-holes connected with folded corrugated holes. This prolongs the distance of high-temperature water in the water-spraying filler layer without increasing the tower height, thereby extending the cooling time of high-temperature water in the tower and improving the cooling effect.

The intelligent controller adjusts the speed of the synchronous motor according to the received data to adjust the energy consumption according to the working conditions. The synchronous motor is directly connected to the axial flow fan without using a reducer, which not only reduces energy consumption and maintenance, but also reduces noise. When combined with a sound-absorbing layer, it can better meet environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0023] As shown in the figure, an intelligent controlled direct-connected energy-saving and environmentally friendly cooling tower includes a cooling tower 1, with a fan unit 4 installed at the top and a cooling water tank 6 installed at the bottom. Cooling tower 1 also includes a water supply pipe 2, which is used to transport high-temperature water into cooling tower 1. The water inlet of water supply pipe 2 is equipped with a signal thermometer 21, which detects the temperature of the high-temperature water entering cooling tower 1 and transmits the high-temperature data to an intelligent controller 11. The outlet of water supply pipe 2 is connected to a water distribution device 3, which distributes the high-temperature water in water supply pipe 2 within the tower. Water distribution device 3 is equipped with several upward-spraying nozzles 31. After being sprayed from water distribution device 3, high-temperature water passes through nozzles 31 and evenly falls into water spraying packing 7. Nozzles 31 can also be positioned as high as possible without increasing the tower height. This increases the distance the high-temperature water travels from nozzles 31 to water spraying packing 7 and the time the high-temperature water stays within the tower, facilitating sufficient cooling. The water sprinkling filler 7 is arranged below the water distribution device 3 and fixed in the cooling tower 1 through the filler bracket 73, and is located above the cooling water pool 6. The guide plate 8 is located below the filler bracket 73 to guide the water cooled by the water sprinkling filler 7 to the cooling water pool 6 below. The water sprinkling filler 7 includes a plurality of S-shaped through hole layers 71 and a plurality of folded through hole layers 72. The plurality of S-shaped through hole layers 71 and the plurality of folded through hole layers 72 are cross-stacked and connected. The S-shaped through hole layer 71 includes a plurality of S-shaped through holes 711, and the folded through hole layer 72 includes a plurality of folded holes 721. We can adjust the number of layers of the S-shaped through hole layer 71 and the folded through hole layer 72 as needed. Taking the stacking of one S-shaped through hole layer 71 and one folded through hole layer 72 as an example, high-temperature water falls from the S-shaped through hole 711 into the folded hole 721. The whole process has a better cooling effect than a straight through hole. The high-temperature water stays in the water sprinkling filler 7 for a longer time, and at the same time, the time the high-temperature water stays in the cooling tower 1 is extended. A portion of the water vapor in the high-temperature water in the tower will float out of the tower. In order to reduce this rising moisture, a water collector 5 is provided between the water distribution device 3 and the fan unit 4. The water collector 5 includes at least one water-blocking layer 51. The water-blocking layer 51 includes several S-shaped condensate pipes 511. Both ends of the S-shaped condensate pipes 511 are provided with straight hole pipes 512. The straight hole pipes 512 are conducive to the rapid dripping of condensed water. When the high-temperature water encounters the S-shaped condensate pipes 511 during the rising process, it will quickly condense into large water droplets and drip down or slide down the inner wall, which can ensure that the water vapor does not float out of the tower to the greatest extent.

[0024] A signal thermometer 2 61 is provided at the outlet of the cooling water pool 6. The signal thermometer 2 61 collects the temperature of the low-temperature water after cooling in the cooling tower 1 and transmits the low-temperature data to the intelligent controller 11. The cooling of the high-temperature water depends not only on the water distribution device 3 and the water spraying filler 7, but also on the fan unit 4. The fan group 4 includes a wind tube 41, in which an axial flow fan 42 is arranged. The bottom end of the axial flow fan 42 is directly connected to a synchronous motor 43. The original technology uses a reducer to connect the axial flow fan 42 and an ordinary AC asynchronous motor. The utility model does not use a reducer but a direct connection to reduce energy consumption. The synchronous motor 43 is a direct-drive reluctance synchronous motor. Replacing an ordinary AC asynchronous motor with a direct-drive reluctance synchronous motor can save more than 20% of electricity. The direct connection of the direct-drive reluctance synchronous motor with the axial flow fan 42 not only eliminates the reducer coupling to reduce energy consumption, but the reducer coupling is also a component with a high frequency of maintenance. Not using a reducer coupling greatly reduces the economic cost and time cost of maintenance. Without a reducer coupling, the cooling tower makes less noise during operation, and is more environmentally friendly when combined with the sound-absorbing layer 9. The selection of the direct-drive reluctance synchronous motor can be customized. Since there is no shaft reducer loss, the power of the direct-drive reluctance synchronous motor can be standardized according to the shaft power, which not only saves electric power but also makes the motor model smaller and more energy-saving. A lightning arrester 44 is installed at the top of the air duct 41, and the synchronous motor 43 is connected to the intelligent controller 11. The intelligent controller 11 adjusts the speed of the synchronous motor 43 based on the difference in data collected from the signal thermometer 1 21 and the signal thermometer 2 61. Using the temperature difference between the signal thermometer 1 21 and the signal thermometer 2 61 to control the speed of the synchronous motor 43 avoids unnecessary high-speed rotation of the synchronous motor 43, thus improving energy conservation. The speed of the synchronous motor 43 can also be controlled in four seasons: spring, summer, autumn, and winter. For example, in winter, the speed of the synchronous motor 43 can be lowered or even stopped to achieve the purpose of cooling the water, making full use of the ambient temperature to reduce the energy consumption of the cooling tower. The synchronous motor 43 directly drives the axial flow fan 42 to rotate. During the rotation process, the axial flow fan 42 draws the hot air in the tower upward and then discharges the hot air outside the tower. The lowered air outside the tower flows into the tower through the louvers, thereby forming a circulation of hot and cold air; since the axial flow fan 42 draws out the hot air upward, the air flow formed by the hot air is upward. The upward air flow has a cooling effect on the falling high-temperature water and can also reduce the falling speed of the water, thereby prolonging the time that the high-temperature water stays in the tower.

[0025] In order to reduce noise interference during the operation of the cooling tower 1, a sound-absorbing layer 9 is attached to the inner wall of the cooling tower 1. The sound-absorbing layer 9 is located in the area above the cooling water pool 6 to reduce dripping noise.

[0026] The shutter 10 is set on the side wall of the cooling tower 1 and is located in the area between the cooling water pool 6 and the water spray filler 7. The shutter can adjust the air intake of the cooling tower 1 and assist in regulating the drop range of high-temperature water.

[0027] During use, industrial high-temperature water enters the cooling tower 1 through the water inlet of the water supply pipe 2, and the signal thermometer 21 collects the high-temperature water data and transmits it to the intelligent controller 11. The high-temperature water is then transported to the water distribution device 3, which sprays the high-temperature water from the nozzle 31. The axial flow fan 42 continues to work to extract the high-temperature air in the cooling tower 1. Most of the water sprayed from the nozzle 31 enters the water sprinkling filler 7, and a small part of it condenses after passing through the water collector 5 above and then falls into the water sprinkling filler 7. The nozzle 31, the water collector 5 and the water sprinkling filler 7 can prolong the time that the high-temperature water stays in the tower, making the cooling effect more obvious. After the water sprinkling filler 7 flows out, it passes through The guide plate 8 is distributed and falls into the cooling water pool 6, and the cold water in the cooling water pool 6 is transported to the industrial equipment for circulation. The signal thermometer 2 61 at the outlet of the cooling water pool 6 collects the low-temperature data after cooling and sends it to the intelligent controller 11. The intelligent controller 11 adjusts the speed of the synchronous motor 43 according to the difference between the collected high-temperature data and the low-temperature data. When the low-temperature data meets the requirements and the high-temperature data remains unchanged, the speed of the synchronous motor 43 is maintained; when the low-temperature data is too low and the high-temperature data remains unchanged, the speed of the synchronous motor 43 is reduced; when the high-temperature data increases, the speed of the synchronous motor 43 needs to be increased to meet the low-temperature data requirements.

[0028] The above embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
