Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to an antifreeze and noise reduction device for a cooling tower in a power plant. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. This evaporative heat dissipation device ensures the normal operation of the system. The device is generally barrel-shaped or hyperbolic, hence the name cooling tower.

[0003] Patent Publication No. "CN214407059U" discloses a "low-energy consumption thermal power plant cooling tower noise reduction device" comprising a base, a plurality of support columns are fixedly mounted on the upper surface of the base, a cooling tower body is fixedly mounted on the upper ends of the plurality of support columns, a shock-absorbing sleeve is fixedly mounted on the inner bottom wall of the cooling tower body, a compression spring is fixedly connected to the inner bottom wall of the shock-absorbing sleeve, a slide plate is overlapped on the upper end of the compression spring, the surface of the slide plate is slidably connected to the inner wall of the shock-absorbing sleeve, and a shock-absorbing telescopic rod is fixedly mounted on the upper surface of the slide plate. The low-energy consumption thermal power plant cooling tower noise reduction device, by arranging a rotating noise reduction plate and a heat sink in the noise reduction cylinder, water drops falling on the noise reduction plate can drive the noise reduction plate to rotate, play a certain buffering role on the water drops, reduce the impact force of the water drops falling on the arc plate, and achieve the purpose of noise reduction. At the same time, the hot water droplets contact the heat sink plate, which can quickly transfer heat and accelerate the cooling of the water droplets.

[0004] In response to the above problems, the device uses a water distribution plate to transport hot water to each spray pipe. The hot water is sprayed out through the spray pipes, and the falling hot water drops on the noise reduction plate, driving the noise reduction plate to rotate. However, after the two side frames of the noise reduction plate rotate, the high-speed flowing water will impact it. The frame cannot effectively absorb the noise and will still cause some noise, which may be emitted intermittently.

[0005] Therefore, the utility model provides a power plant cooling tower antifreeze noise reduction device to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides an antifreeze and noise reduction device for a cooling tower in a power plant, which solves the above-mentioned problems. The hot water is controlled to be sprayed out from the spray pipe through a spray system. The hot water will first be sprayed into the sound insulation groove. Due to the good sound absorption effect of the sound insulation groove, most of the noise can be absorbed. Then the water flows through the bottom of the sound insulation groove through the guide tube and flows into the disc. The servo motor will drive the disc to rotate. At this time, the water will be thrown onto the inner wall of the ring due to inertia, and then many small water droplets will be formed along the inner wall of the ring and flow to the outer surface of the vertebral block. Then the water will slowly flow into the water reservoir through the curved surface of the vertebral block. The whole process makes the water flow fall in a stepped manner, and avoids a large amount of water gathering into a ball and falling directly into the water reservoir. It can also effectively Reduce noise formation; by starting the constant temperature warehouse to make its interior reach a lower temperature, and then starting the circulating water pump to circulate the coolant in the conduit, the heat accumulated on the outer surface of the vertebral block due to the flow of hot water can be taken away, and sent to the constant temperature warehouse through the conduit for rapid heat exchange and cooling.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0030] The present application is further described in detail below through drawings and examples.

[0031] Reference Figures 1 to 5 The embodiment of the present application provides a power plant cooling tower antifreeze noise reduction device, including a tower body 1, a noise reduction component 2 is arranged inside the tower body 1, and a circulating temperature control component 3 is arranged outside the tower body 1; the noise reduction component 2 includes a water reservoir 28, a base 21 is fixedly connected to the bottom of the water reservoir 28, a cone block 22 is fixedly connected to the top of the base 21, a mounting frame 23 is fixedly connected to the inner wall of the tower body 1, a nozzle 24 is fixedly installed at the bottom of the mounting frame 23, and one end of the nozzle 24 can be connected to an external pipeline, and a sound insulation groove 25 is also fixedly connected to the inner wall of the tower body 1, a guide tube 26 is fixedly connected to one end of the sound insulation groove 25, and a ring 27 is fixedly connected to the inner wall of the tower body 1. A servo motor 29 is fixedly installed inside the cone block 22, and a disc 210 is fixedly connected to the output shaft of the servo motor 29. The sound insulation groove 25 is made by splicing and fixing a plurality of sound absorbing panels.

[0032] In specific implementation: the hot water is sprayed out from the nozzle 24 through the spray system, and the hot water will first be sprayed into the sound insulation groove 25. Due to the good sound absorption effect of the sound insulation groove 25, most of the noise can be absorbed. Then the water flows through the bottom of the sound insulation groove 25 through the guide tube 26 and flows into the disc 210. The servo motor 29 drives the disc 210 to rotate. At this time, the water will be thrown onto the inner wall of the ring 27 due to inertia, and then many small water droplets will be formed along the inner wall of the ring 27 and flow to the outer surface of the vertebral curved block 22. Then, the water will slowly flow into the water reservoir 28 through the curved surface of the vertebral curved block 22. The whole process makes the water flow fall in a step-by-step manner and avoids a large amount of The water gathers into a ball and falls directly into the water reservoir 28, which can also effectively reduce the formation of noise (sound-absorbing materials are mainly divided into microporous type and fiber type, and there is no essential difference between them. The principle of sound absorption is to leave a channel for sound to enter, a channel composed of countless tiny holes connected together, or countless tiny gaps formed by countless fibers crossing and mixing together, but once the sound enters, it cannot come out. Because the channel is too messy and too long, the sound drills in it and bumps left and right, gradually consuming energy in the process, which plays a role in sound absorption. Commonly used materials for sound-absorbing panels include glass fiber, rock wool, foam plastic, wood material, metal, etc.).

[0033] Reference Figures 1 to 5 In one aspect of this embodiment, the circulating temperature control assembly 3 includes a ventilator 36, which is fixedly mounted on the outer wall of the tower body 1, and a ventilation pipe 35 is fixedly connected to one side of the ventilator 36, and the ventilation pipe 35 penetrates the side wall of the tower body 1 and extends into the interior. A conduit 33 is fixedly mounted inside the vertebral curved block 22, and the conduit 33 is filled with coolant inside, and the conduit 33 penetrates the side wall of the tower body 1. The circulating temperature control assembly 3 also includes a constant temperature storehouse 31, and one end of the conduit 33 is fixedly mounted inside the constant temperature storehouse 31. A circulating water pump 34 is fixedly mounted between the pipe bodies of the conduit 33, and the circulating temperature control assembly 3 also includes a mounting base 32, and the top of the mounting base 32 is fixedly connected to the circulating water pump 34.

[0034] During specific implementation: by starting the constant temperature storehouse 31 to make its interior reach a lower temperature, and then starting the circulating water pump 34 to circulate the coolant in the conduit 33, the heat accumulated on the outer surface of the vertebral block 22 due to the flow of hot water can be taken away, and sent to the constant temperature storehouse 31 through the conduit 33 for rapid heat exchange and cooling, and the interior of the constant temperature storehouse 31 can also be heated, so that the coolant in the conduit 33 has heat, which can be transmitted to the vertebral block 22 in winter, so that the vertebral block 22 has sufficient temperature to prevent ice from freezing on the surface, and can also radiate heat to the surroundings, and start the ventilator 36 to blow the cold air from the outside into the interior of the tower body 1 through the ventilation pipe 35. After the two streams of cold air meet, they will form convection with the hot air heated by the hot water flow radiation, so that the hot air rises and flows to accelerate the cooling efficiency (air convection refers to the air flow phenomenon formed by uneven heating of the air, the heated air expands and rises, and the cooled air sinks).

[0035] All electrical equipment in this solution are powered by an external power supply.

[0036] Working principle: The hot water is sprayed out from the nozzle 24 through the spray system. The hot water will first be sprayed into the soundproof groove 25. Due to the good sound absorption effect of the soundproof groove 25, most of the noise can be absorbed. Then the water flows through the bottom of the soundproof groove 25 through the guide tube 26 and flows into the disc 210. The servo motor 29 drives the disc 210 to rotate. At this time, the water will be thrown onto the inner wall of the ring 27 due to inertia, and then many small water droplets will be formed along the inner wall of the ring 27 and flow to the outer surface of the cone block 22. Then the water will slowly flow into the water reservoir 28 through the curved surface of the cone block 22. The whole process makes the water flow fall in a step-by-step manner, and avoids a large amount of water gathering into a ball and falling directly into the water reservoir 28. It can also effectively reduce the formation of noise. By starting the constant temperature storage 3 1 so that its interior reaches a lower temperature, and then the circulating water pump 34 is started to circulate the coolant in the conduit 33, so that the heat accumulated on the outer surface of the vertebral curved block 22 due to the flow of hot water can be taken away, and sent to the constant temperature storehouse 31 through the conduit 33 for rapid heat exchange and cooling, and the interior of the constant temperature storehouse 31 can also be heated, so that the coolant in the conduit 33 has heat, which can be transferred to the vertebral curved block 22 in winter, so that the vertebral curved block 22 has enough temperature to prevent ice from freezing on the surface, and can also radiate heat to the surroundings, and the ventilator 36 is started to blow the cold air from the outside into the interior of the tower body 1 through the ventilation pipe 35. After the two streams of cold air meet, they will form convection with the hot air heated by the hot water flow radiation, so that the hot air rises and flows to accelerate the cooling efficiency.
