Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to an energy-saving and noise-reducing cooling tower. Background Art

[0002] A cooling tower is a device used to reduce the heat generated by industrial equipment or buildings. It is usually used in industries such as air conditioning, power plants, and chemical plants. It reduces the water temperature by contacting hot water with air, thereby dissipating the heat into the air. During the use of the cooling tower, hot water needs to be sprayed so that the hot water is in even contact with the air, thereby achieving a better heat dissipation effect.

[0003] As in the prior art, a Chinese patent with authorization announcement number CN111981866B discloses a cooling tower, in which a first spray layer and a second spray layer for spraying circulating water are provided inside the tower body of the cooling tower, and a heat exchange layer is provided between the first spray layer and the second spray layer; the heat exchange layer includes a heat exchange module, and the heat exchange module is provided with a first flow channel for humid hot air to flow through and a second flow channel for dry cold air to flow through, and an opening is provided at the upper end of the first flow channel for the humid hot air to flow out and for the circulating water sprayed by the second spray layer to flow in. This arrangement improves the demisting effect and cooling effect of the cooling tower, and enables the heat exchange module to play a role similar to that of the packing layer.

[0004] For another example in the prior art, a Chinese patent with the authorization announcement number CN105004197A discloses a cooling tower, wherein an air inlet and an air outlet are provided on the cooling tower body, the fan is provided at the air inlet of the cooling tower body, the water inlet pipe is provided in the cooling tower body, the filler is located between the nozzle and the air inlet, and further includes a water baffle, which is provided in the cooling tower body and below the water inlet pipe, and the nozzles are evenly distributed on the water baffle. The design of directly installing the traditional nozzle on the water inlet pipe is changed to installing the nozzle on the water baffle. Compared with the water inlet pipe, the water baffle can be installed with more nozzles, and even if a nozzle is blocked, it will not affect the quality of the water mist too much, thereby ensuring the cooling effect of the cooling tower.

[0005] Based on the above materials, it can be known that in the prior art, a nozzle spraying method is usually adopted to make hot water contact with the filler to achieve the purpose of heat dissipation. However, in actual use, the hot water falls directly on the filler after being sprayed by the nozzle. The short time makes the contact between the hot water and the air insufficient, resulting in unsatisfactory heat dissipation effect and increased overall energy consumption of the device. Summary of the invention

[0008] Preferably, mounting rods are fixedly mounted at the four corners of the lower surface of the mounting plate, and the mounting rods slide through the inner wall of the upper box body, and a first spring is arranged outside the mounting rods.

[0009] Preferably, the swing mechanism includes a first magnetic block fixedly mounted on the right outer surface of the blocking plate, and a through-type sliding structure is formed between the blocking plate and the guide slide rod, and the guide slide rod is fixedly mounted on the upper surface of the mounting plate, and a second spring is installed on the left outer side of the guide slide rod.

[0010] Preferably, the positions of the first magnetic block and the second magnetic block correspond to each other, the first magnetic block and the second magnetic block have the same magnetic pole, and the second magnetic block is fixedly mounted on the outer surface of the right telescopic cylinder.

[0011] Preferably, the cooling mechanism comprises a cooling pipe fixedly installed inside the heat dissipation filler, and the cooling pipe is configured as a bent structure, and the cooling pipe is interconnected with the circulation box through a conveying pipe.

[0012] Preferably, the circulation box is fixedly mounted on the lower surface of the upper box body, and an airbag is fixedly mounted on the upper surface of the circulation box, and the airbag and the circulation box are connected to each other.

[0013] Preferably, piston plates slidably connected to the circulation box are fitted on the left and right sides of the circulation box, and semiconductor refrigeration plates are fixedly installed inside the circulation box.

[0014] Preferably, a through groove structure communicating with the filling sponge is provided on the upper surface of the lower box body, and sound-absorbing holes arranged in a matrix are provided inside the filling sponge.

[0015] Preferably, shock-absorbing springs are fixedly installed between the upper surface of the lower box body and the lower surface of the upper box body, and the shock-absorbing springs are distributed at equal intervals.

[0016] Preferably, an electric control valve is fixedly installed in the middle position of the connecting pipe, and a shunt pipe connected with the connecting pipe is fixedly installed on the side of the electric control valve, and the shunt pipe is inserted into the filling sponge.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the energy-saving and noise-reducing cooling tower adopts a new structural design, the specific contents of which are as follows: 1. The device uses atomizing nozzles arranged at equal intervals outside the spray pipe to spray hot water that needs to be cooled. The sprayed hot water passes through the heat dissipation filler and contacts the air brought in by the heat dissipation fan, and the purpose of cooling is achieved by heat exchange or evaporation heat absorption. The cooled water is discharged from the outlet pipe for recycling; Furthermore, during the operation, the telescopic cylinder is opened to drive the mounting plate to move up and down, and during the movement of the mounting plate, the blocking plate above it is driven to move synchronously (the blocking plate can block the water mist from falling and slow down its falling speed, so that the water mist can be more fully in contact with the air). When the first magnetic block on the side of the blocking plate moves to the position corresponding to the second magnetic block, the repulsive force between the magnetic blocks is used to make the blocking plate slide outside the limit slide rod, and then the blocking plate is reset under the elastic pulling action of the second spring, and finally the blocking plate is swung left and right, so that it stirs the sprayed water mist, increases the contact area between the water mist and the air, and achieves a better cooling effect. Furthermore, when the mounting plate moves up and down, the heat dissipation filler underneath it is used to squeeze the airbag. At this time, the piston plate in the circulation box moves left and right according to the pressure under the blowing action of the airbag. The piston plate is used to circulate the coolant of the circulation box in the cooling pipe through the delivery pipe (the coolant is cooled by the refrigeration plate of the circulation box), so that the cooling pipe cools the heat dissipation filler, thereby ensuring the heat exchange effect of the heat dissipation filler during long-term use.

[0018] 2. A shock-absorbing spring is fixedly installed between the upper box and the lower box. The elastic effect of the shock-absorbing spring is combined with the filling of the filling sponge so that the vibration of part of the box can be absorbed when the device is in use, thereby achieving the purpose of shock reduction. As the vibration is reduced, the overall noise of the device is also greatly reduced (sound-absorbing holes are opened inside the filling sponge to better reduce noise), avoiding the impact of large noise on surrounding staff; Furthermore, the cooled water is transported to the lower box through the connecting pipe and then discharged. After a period of use, the electric control valve can be switched to allow the water to be discharged from the diversion pipe. The water in the diversion pipe flows into the filling sponge, and the filling sponge is used to filter the water to remove some impurities (such as scale, rust, etc.) that may be produced therein, so as to prevent the impurities from affecting the subsequent use of the water.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] Example 1: Please refer to Figure 1-Figure 3 In order to achieve the purpose of cooling the hot water, the present embodiment provides the following technical solutions, which utilize the heat exchange between the hot water and the air in combination with the evaporation heat absorption to achieve the cooling effect, and specifically discloses: an upper box body 1 and a lower box body 2 corresponding to each other, an inspection door 3 is fixedly installed on the front side of the upper box body 1 by bolts, two cooling fans 4 are rotatably installed on the upper part of the upper box body 1, and a water inlet pipe 5 is fixedly installed on the upper end of the left side of the upper box body 1, and a water outlet pipe 6 is fixedly installed on the left side of the lower box body 2, a spray pipe 7 connected with the water inlet pipe 5 is fixedly installed on the upper end of the upper box body 1, and atomizing nozzles 8 are evenly installed on the outside of the spray pipe 7 at equal intervals, an air inlet grille 11 for entering the air is fixedly opened on the front and rear sides of the upper box body 1, and a connecting pipe 12 for mutual communication is fixedly installed between the upper box body 1 and the lower box body 2, a transversely arranged mounting plate 9 is installed inside the upper box body 1, and telescopic cylinders 13 are installed on the left and right sides of the upper surface of the mounting plate 9, and the telescopic cylinder 13 is fixedly installed on the inner wall of the upper box body 1, and a heat dissipation filler 10 is fixedly installed on the lower surface of the mounting plate 9.

[0023] When using the device, first turn on the water pump connected to the water inlet pipe 5, and transport the hot water generated in the factory production process to the spray pipe 7 through the water inlet pipe 5. Then the hot water is sprayed out from the atomizing nozzle 8 evenly arranged outside the spray pipe 7. At the same time, turn on the cooling fan 4 above the upper box body 1. Under the rotation of the cooling fan 4, the external air is sucked into the upper box body 1 through the air inlet grille 11. The incoming air contacts with the water mist for heat exchange, and part of the water mist evaporates and absorbs heat. Then the water mist falls into the heat dissipation filler 10, and the heat dissipation filler 10 is used to evenly dissipate heat and cool it. The cooled water falls on the bottom of the upper box body 1 and is transported to the lower box body 2 through the connecting pipe 12, and is finally discharged through the water outlet pipe 6 on the side of the lower box body 2.

[0024] Example 2: Please refer to Figure 4-Figure 8In order to solve the problem that the water area and air contact time of the traditional device is short during use, resulting in an unsatisfactory cooling effect, the present embodiment provides the following technical solutions, wherein the falling water mist is stirred by the blocking plate 16 and the heat is dissipated to the heat dissipation filler 10 to ensure its overall cooling effect, and specifically discloses: a cooling mechanism for cooling the heat dissipation filler 10 is arranged inside the heat dissipation filler 10, and blocking plates 16 evenly distributed at equal intervals are arranged above the mounting plate 9, and a swing mechanism for driving the blocking plate 16 to move left and right is arranged on the side of the blocking plate 16, and mounting rods 14 are fixedly installed at the four corners of the lower surface of the mounting plate 9, and the mounting rods 14 penetrate and slide with the inner wall of the upper box body 1, and a first spring 15 is arranged outside the mounting rod 14, and the swing mechanism includes a first magnetic block 19 fixedly installed on the outer surface of the right side of the blocking plate 16, and a through-type sliding structure is formed between the blocking plate 16 and the guide slide bar 17, and the guide slide bar 1 7 is fixedly mounted on the upper surface of the mounting plate 9, a second spring 18 is mounted on the left side of the guide slide bar 17, the positions of the first magnetic block 19 and the second magnetic block 20 correspond to each other, and the first magnetic block 19 and the second magnetic block 20 have the same magnetic poles, and the second magnetic block 20 is fixedly mounted on the outer surface of the right telescopic cylinder 13, the cooling mechanism includes a cooling pipe 22 fixedly mounted inside the heat dissipation filler 10, and the cooling pipe 22 is arranged as a bent structure, and the cooling pipe 22 is interconnected with the circulation box 21 through the conveying pipe 2101, the circulation box 21 is fixedly mounted on the lower surface inside the upper box body 1, and a blast airbag 23 is fixedly mounted on the upper surface of the circulation box 21, and the blast airbag 23 and the circulation box 21 are interconnected, piston plates 24 slidably connected thereto are fitted on the left and right sides of the circulation box 21, and a semiconductor-type refrigeration sheet 25 is fixedly mounted inside the circulation box 21.

[0025] During the use of the device, the telescopic cylinder 13 is turned on, and the telescopic cylinder 13 is used to drive the mounting plate 9 to move up and down reciprocatingly. During this process, the mounting rods 14 at the four corners of the lower surface of the mounting plate 9 slide through the upper box body 1, and the first spring 15 is used to achieve the purpose of buffering. The blocking plate 16 above the mounting plate 9 blocks the falling water mist, slows down the falling speed of the water mist, thereby increasing the contact time between the water mist and the air. When the mounting plate 9 moves to the upper side, it drives the first magnetic block 19 to move to the position corresponding to the second magnetic block 20. At this time, the magnetic repulsion between the first magnetic block 19 and the second magnetic block 20 is used to push the blocking plate 16 to move to the left side (the blocking plate 16 slides accordingly outside the guide slide bar 17). When the mounting plate 9 moves to the lower side, the first magnetic block 19 and the second magnetic block 20 are staggered and lose the repulsive force. At this time, The elastic action of the second spring 18 pushes the blocking plate 16 to the right and resets it, so that the blocking plate 16 swings back and forth to achieve the purpose of stirring the water mist and further expand the contact area between the water mist and the air. When the mounting plate 9 moves up and down, it drives the heat dissipation filler 10 fixedly installed on its lower surface to move synchronously, so that the heat dissipation filler 10 is used to squeeze the airbag 23, and the air pressure inside the circulation box 21 is changed by the compression and expansion of the airbag 23. The change in air pressure is used to make the piston plate 24 inside the circulation box 21 move back and forth, and the movement of the piston plate 24 is used to transport the coolant in the circulation box 21 from the delivery pipe 2101 to the cooling pipe 22 (the coolant is cooled by the semiconductor refrigeration plate 25 in the circulation box 21), so as to cool the heat dissipation filler 10, thereby ensuring the long-term use effect of the heat dissipation filler 10.

[0026] Example 3: Please refer to Figure 9-10 In order to solve the problem of noise generated by vibration during use of the device, the present embodiment provides the following technical solution to reduce the overall noise of the device through a shock-absorbing mechanism. Specifically, the following technical solution is disclosed: a filling sponge 26 is fixedly installed on the upper surface of the lower box body 2, a through groove structure connected to the filling sponge 26 is provided on the upper surface of the lower box body 2, and sound-absorbing holes 27 arranged in a matrix are provided inside the filling sponge 26; shock-absorbing springs 28 are fixedly installed between the upper surface of the lower box body 2 and the lower surface of the upper box body 1, and the shock-absorbing springs 28 are distributed at equal intervals; an electric control valve 29 is fixedly installed in the middle position of the connecting pipe 12, and a shunt pipe 30 connected to the connecting pipe 12 is fixedly installed on the side of the electric control valve 29, and the shunt pipe 30 is inserted into the filling sponge 26.

[0027] The device generates vibrations during use (such as vibrations caused by the rotation of the cooling fan 4). The elastic effect of the shock-absorbing spring 28 between the upper box body 1 and the lower box body 2 is used in conjunction with the damping effect of the filling sponge 26 to achieve the purpose of shock absorption. The noise during the operation of the device is reduced by shock absorption (at the same time, the sound-absorbing holes 27 evenly opened inside the filling sponge 26 can absorb part of the noise), so as to avoid the noise affecting the activities of the surrounding staff. After the device has been used for a period of time, the electric control valve 29 is switched so that the water in the upper box body 1 after cooling is discharged from the shunt pipe 30. The shunt pipe 30 discharges the water into the filling sponge 26, and the filling sponge 26 is used to filter impurities (such as scale and rust, etc.) therein. The water filtered by the filling sponge 26 flows into the lower box body 2, so as to avoid the impurities affecting the subsequent recycling of water.
