Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and more specifically, to an anti-fogging and water-saving cooling tower. Background Technology

[0002] A cooling tower is a device that uses circulating water to dissipate heat. It allows water to absorb heat from the system and then exchange heat with flowing air. The water evaporates to form steam, carrying away the heat. Combined with convection and radiation, this ultimately discharges waste heat generated in industrial processes or refrigeration / air conditioning systems into the atmosphere, thus lowering the water temperature.

[0003] Utility model patent application publication number 202420199390.9 discloses a low-carbon, fog-eliminating, and water-saving cooling tower, comprising a tower body, a biomimetic fiber membrane, a condensation device, a semiconductor thermoelectric generator module, ceramic oblique cross-packing, a circulating water outlet pipe, a bottom battery, a water collection tank, a photovoltaic power generation device, a circulating water inlet pipe, a sprayer, a top battery, a DC / AC converter, a fan, and an air inlet. The condensation device, as the first condensation and fog-eliminating process, enhances the cooling tower's fog-eliminating and water-saving performance. The biomimetic fiber membrane, composed of layers of polymer-based biomimetic phospholipids, forms the second condensation and fog-eliminating process, further intercepting water droplets from the rising humid air inside the tower. The ceramic oblique cross-packing is corrosion-resistant, acid and alkali-resistant, freeze-resistant, and has good heat exchange performance. The photovoltaic power generation device and the semiconductor thermoelectric generator module enable the cooling tower to self-supply its power, reducing energy consumption and achieving energy saving and low carbon emissions. This utility model cooling tower significantly improves its condensation and fog-eliminating, low-carbon, and environmentally friendly performance.

[0004] 1. Although the condenser can condense moisture in the hot and humid air, the continuously forming droplets accumulate on the outer wall of the cooling water pipe, gradually forming a continuous water film. This water film forms an additional thermal resistance layer between the cooling water pipe and the hot and humid air, severely hindering the direct contact between the moisture and the cold pipe wall and efficient heat conduction, resulting in a significant reduction in the overall condensation heat exchange efficiency.

[0005] 2. When using biomimetic fiber membranes for secondary demisting, as the fibers continuously absorb moisture, the surface tension of the water causes the droplets to expand and connect between the fibers, forming a covering film. This liquid film blocks the tiny pores between the fibers, significantly increasing airflow resistance, hindering the smooth upward flow of hot and humid air, and ultimately weakening the ventilation and cooling efficiency of the cooling tower.

[0006] 3. The device uses condenser balls to increase the condensation surface area. However, the effective contact area increase provided by the condenser balls is relatively limited, and their stacking method may create ineffective space. This limited surface area expansion is unlikely to significantly improve the condensation rate of water vapor in humid and hot air, resulting in a lack of significant improvement in the expected defogging and water-saving effects.

[0007] Therefore, there is an urgent need for a mist-eliminating and water-saving cooling tower. Utility Model Content

[0025] Please see Figures 1-6The drive structure includes gears 14 with equal spacing. The gears 14 are fixedly connected to the adjacent cooling pipes 12. The fixed cover 8 is fixedly connected to two fixed brackets 15. A rack 16 is slidably connected between the two fixed brackets 15. The rack 16 meshes with the gears 14. The rack 16 is fixedly connected to a fixed plate 17. The fixed plate 17 is provided with a through groove. The cooling tower shell 2 is fixedly connected to a motor 18. The output end of the motor 18 is fixedly connected to a fixed disk 19. The fixed disk 19 is fixedly connected to a fixed column 20. The fixed column 20 slides in the through groove of the fixed plate 17.

[0026] Please see Figure 2 , Figure 7 and Figure 8 The exhaust structure includes a fixed ring 21, which is fixed to the inner wall of the cooling tower shell 2. A conical plate 22 is rotatably connected to the fixed ring 21. The conical plate 22 is provided with circumferentially spaced through holes. Multiple water-absorbing fibers 23 are fixedly connected inside the through holes of the conical plate 22. A sliding frame 24 is slidably connected to the exhaust outlet of the cooling tower shell 2. Two electric push rods 25 are fixedly connected to the cooling tower shell 2. A connecting frame 26 is fixedly connected between the telescopic end of the electric push rod 25 and the sliding frame 24. A second motor 27 is fixedly connected to the sliding frame 24. A fan blade 28 is fixedly connected to the output shaft of the second motor 27. The output shaft of the second motor 27 passes through the upper side of the conical plate 22. A friction plate 29 is fixedly connected to the output end of the second motor 27.

[0027] Working principle: Hot water is pumped into the inlet pipe 5 by a water pump. The hot water flows out from the distribution pipe 6 and is sprayed onto the packing layer 7. At the same time, the second motor 27 is started. The output end of the second motor 27 drives the fan blade 28 to rotate circumferentially. Under the action of the fan blade 28, the outside air enters the cooling tower shell 2 through the grille 3. The outside air flows upward through the packing layer 7, thereby cooling the hot water. The cooled water flows into the base 1 and is then discharged outward through the drain pipe 4.

[0028] During the above process, cooling water is pumped into flange pipe 10. The cooling water flows out from flange pipe 11 through U-shaped pipe 9 and cooling pipe 12. When the upward-moving hot and humid air comes into contact with cooling pipe 12, the moisture in the hot and humid air condenses into small liquids on cooling pipe 12 and heat dissipation fins 13, thereby reducing the moisture content in the hot and humid air. After a period of time, the droplets will cause the cooling pipe 12 and heat dissipation fins 13 to rotate, which will hinder the heat exchange between the cooling pipe 12 and heat dissipation fins 13 and the hot and humid air. Then, motor 18 is started. The output shaft of motor 18 drives the fixed plate 19 to rotate circumferentially. The fixed plate 19 drives the fixed column 20. The device slides along the through groove of the fixed plate 17, which in turn causes the fixed plate 17 to drive the rack 16 to slide back and forth along the two fixed frames 15. The rack 16 drives the gear 14 to rotate back and forth, causing the cooling pipe to rotate back and forth along the U-shaped tube 9. The cooling pipe 12 drives the heat dissipation fins 13 on it to rotate back and forth, shaking off the liquid droplets attached to the cooling pipe 12 and the heat dissipation fins 13. Then the motor 18 is turned off. By cleaning the liquid droplets on the cooling pipe 12 and the heat dissipation fins 13, the heat exchange efficiency between the cooling pipe 12 and the heat dissipation fins 13 and the humid air is improved, and the moisture in the humid air is condensed. The dripping water droplets re-enter the base 1, thereby achieving the purpose of defogging and water saving.

[0029] As the hot and humid air continues to rise, when the remaining moisture in the hot and humid air comes into contact with the absorbent fiber 23, the absorbent fiber 23 further processes the moisture in the hot and humid air, reducing the water content of the hot and humid air. After a period of use, the two electric push rods 25 are activated. The telescopic ends of the two electric push rods 25 drive the sliding frame 24 to move upward. The sliding frame 24 slides upward along the outer shell 2 of the cooling tower. The sliding frame 24 drives the second motor 27 to move upward. The output shaft of the second motor 27 drives the friction plate 29 to move upward. The friction plate 29 contacts the conical plate 22, thereby driving the conical plate 22 to rotate circumferentially through the friction plate 29. The conical plate 22 drives the absorbent fiber 23 on it to rotate circumferentially. Under the action of centrifugal force, the liquid adsorbed on the absorbent fiber 23 is cleaned. The cleaned water flows back into the base 1 through the through hole of the fixed cover 8.
