Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a high-position water collection cooling tower. Background Art

[0002] A cooling tower is a device that uses the contact between water and air to dissipate waste heat generated in industry or refrigeration and air conditioning through evaporation. The basic principle is: dry (low enthalpy) air enters the cooling tower from the air inlet after being pumped by the fan; high-temperature water molecules with large saturated steam partial pressure flow to the air with low pressure, and humid (high enthalpy) water is sprinkled into the tower from the water seeding system. When water droplets come into contact with air, on the one hand, due to the direct heat transfer between air and water, and on the other hand, due to the pressure difference between the water vapor surface and the air, evaporation occurs under the action of pressure, that is, the sensible heat of the water is taken away by heat transfer with unsaturated dry air, and part of the water evaporates to take away the latent heat in the water, thereby achieving the purpose of cooling the cooling water. After searching, the prior art (application number: CN202221802068.8) records "a water collection trough of a high-level water collection cooling tower, which relates to the technical field of high-level water collection cooling towers. The utility model includes a water collection trough body arranged on a support beam of a high-level water collection cooling tower, the water collection trough body includes a plurality of water collection trough sections and a connecting flange, and the plurality of water collection trough sections are connected side by side through a connecting flange to form a water collection trough body, a drain port is arranged at the bottom of the water collection trough body, an upper pull beam and a lower pull beam are arranged in the water collection trough section, and the upper pull beam and the lower pull beam are at different plane heights, and a water collection short groove is arranged on the outer wall of the water collection trough section, and the water collection short groove is connected to the water collection trough of the high-level water collection cooling tower through an interface flange, and the water collection trough of the high-level water collection cooling tower and the water collection trough body are connected through the water collection short groove. The utility model is installed on the support beam of the high-level water collection cooling tower in a splicable form, has high stability, light weight, and is easy to install, and can reduce the load of the high-level water collection cooling tower."

[0003] Although the high-position water collection cooling tower in the prior art has achieved stable installation of the water collecting tank, there are still some shortcomings: the water collecting tank involved in the existing high-position water collection cooling tower can only collect the cooled water, and cannot actively cool the cooling water inside it, resulting in a deviation in the single air cooling effect during the cooling water circulation; secondly, the dehumidifier structure involved in the existing cooling tower is mostly a parallel arranged curved plate structure, and the water vapor escapes outward through the gap between the curved plates, resulting in a part that cannot collide between the water vapor and the curved plates. Although the existing dehumidifier can achieve more than 80% of the water source retention effect, there is still evaporation waste of cooling water. Utility Model Content

[0006] Furthermore, the water inlet of the circulation pump is connected to the bottom of the water collecting tank, and the water outlet of the circulation pump is connected to the outer end of the spray pipe through a vertical pipe, and the spray pipe is located between the dehumidifier and the filler.

[0007] Furthermore, the curved coil is arranged in an S-shaped structure and laid at the bottom of the water collection tank, and a support rod is connected to the lower side of the curved coil, and a nozzle is connected to the upper side wall of the curved coil.

[0022] In this embodiment, the water collecting tank 1, the cooling cylinder 2 and the exhaust cylinder 3 and their internal components constitute the main structure of the high-level water collection cooling tower involved in this application.

[0023] As a preferred embodiment, by setting up a blower 13, on the one hand, air is blown to the water in the water collection tank 1 to cause tumbling to achieve further heat dissipation. On the other hand, under the exhaust action of the exhaust fan 31, sufficient air intake is ensured at the bottom of the tower body, and then when the water vapor is affected by the dehumidifier 22 with a larger interception area, a large ventilation volume can be maintained, thereby auxiliary and strengthening the cooling effect of the exhaust fan 31 and the filler 21.

[0024] Specifically, a pressure check valve is provided inside the nozzle 16 so that the water in the water collecting tank 1 can be blocked when no air is discharged. Under the wind pressure of the blower 13, the pressure check valve is opened to achieve the exhaust effect.

[0025] Specifically, the lower end of the rotating shaft is inserted into the water collecting tank 1, avoiding the position of the curved coil 15, and is rotatably connected to the bottom of the tank, so as to enhance the rotation stability of the exhaust fan 31.

[0026] As a preferred embodiment, a stirring blade may be connected to the outer wall of the portion of the rotating shaft located in the water collecting tank 1, so that when the exhaust fan 31 rotates, the internal cooling water is stirred and the heat is dissipated.

[0027] like Figure 1 , Figure 2 and Figure 3As shown, the water inlet end of the circulation pump 12 is connected to the bottom of the water collecting tank 1, and the water outlet end of the circulation pump 12 is connected to the outer end of the spray pipe 23 through a vertical pipe, and the spray pipe 23 is located between the dehumidifier 22 and the filler 21, the upper end of the curved plate 221 is connected to a connecting plate 222, and the two ends of the connecting plate 222 are fixed to the inner wall of the cooling cylinder 2, the baffle 223 is set to a V-shaped structure, and in the length direction of the curved plate 221, the same spacing is set between adjacent baffles 223, the upper side of the cooling cylinder 2 is provided with an open mouth, and a cross bracket is provided in the open mouth, and the exhaust cylinder 3 is fixed on the cross bracket.

[0028] Specifically, a cooling water outlet is provided on the rear outer wall of the water collecting tank 1, so that the cooled hot water becomes cold water and is pumped out to continue cooling the external equipment. Then the hot water heated by the equipment enters the water collecting tank 1 through the hot water inlet 11 to achieve a circulating cooling effect.

[0029] As a preferred embodiment, by setting up multiple groups of baffles 223, the gaps between the curved plates 221 included in the original dehumidifier 22 are made up, thereby increasing the water vapor collision area, and the air intake is increased by the blower 13. At the same time, upward air pressure can be formed inside the tower body, thereby compensating for the defect of poor exhaust caused by the set baffles 223.

[0030] When in use, the hot water is pumped to the spray pipe by a circulating pump, and then passes through the exhaust fan and filler to exchange heat with the flowing air for cooling, and then falls into the water collection tank. At this time, the blower is started, and the air inlet pipe, the curved coil, and the nozzle are used to spray air at the bottom of the water collection tank, thereby raising bubbles in the water tank, driving the cooling water to roll, and achieving the effect of further cooling the internal cooling water, which is convenient for recycling. The curved plate and the baffle plate included in the dehumidifier are used to make part of the hot steam collide with the curved plate, and part of the hot steam collide with the baffle plate. When the water droplets entrained in the steam pass through the wave-shaped or arc-shaped gaps of each piece of the dehumidifier, the water droplets hit the side wall of the dehumidifier sheet due to their large inertia, and then the water is collected and falls back into the water collection tank in the tower. At the same time, part of the water droplets hit the baffle plate, and through the inverted V-shaped structure of the baffle plate, they are also returned to the water collection tank, thereby achieving the effect of double-layer filtration and interception, increasing the interception area, and then increasing the water recovery filter, reducing the waste of water resources.

[0031] The high-level water collection cooling tower of the utility model can effectively solve the problems that the water collection tank involved in the existing high-level water collection cooling tower cannot further cool the circulating water, and the dehumidifier involved still has a lot of water waste during use. It realizes further cooling of the circulating water in the water collection tank on the basis of the existing high-level water collection cooling tower technology, and at the same time increases the recovery rate of the circulating water by the dehumidifier, further reducing water waste.
