Description

Technical Field

[0001] The invention belongs to the technical field of cooling tower spraying, and in particular relates to a spraying mechanism of a thermal power generation cooling tower. Background Art

[0002] Thermal power cooling tower is an important facility in thermal power plants, used for heat dissipation. In thermal power plants, a large amount of heat is generated when the steam turbine generates electricity. In order to maintain the normal operation of the power generation equipment, this heat needs to be dissipated. The cooling tower brings hot water into the tower through a water circulation system, and the water and air in the tower exchange heat, so that the water is cooled and then flows back to the power generation equipment to complete the cycle. This tower-like structure is usually very high to increase the contact area between air and water and improve the heat dissipation efficiency.

[0003] In coastal cities, whether it is a nuclear power plant or a thermal power plant, the cooling water to maintain the operation of the equipment can be directly cooled by seawater. However, in inland areas, such a large amount of water cannot be used for direct cooling. The cooling water of inland thermal power plants forms exhaust steam when passing through the turbine. The temperature of this exhaust steam is not high, about 40 to 50 degrees, but its pressure is low, close to a vacuum. The exhaust steam then passes through the condenser and is cooled into water. After becoming water, it re-enters the boiler to complete the cycle. The water used by the condenser to cool the water comes from the water cooled by the cooling tower. Therefore, the cooling water will continue to circulate between the condenser and the cooling tower to cool the exhaust steam.

[0004] However, in the prior art, cooling water is consumed greatly during use and needs to be supplemented with conventional water. Conventional water will form scale in the sprayer after heating, and long-term use will affect the water spraying efficiency. The conventional maintenance method is to replace a new atomizing nozzle, and it will not be blocked due to problems with one or several nozzles. It will only be replaced when a large number of nozzles are slow to discharge water. After the replacement, the nozzle is placed in dilute hydrochloric acid to dissolve and clean the scale. This method is inefficient and requires stopping the equipment for operation, which affects the cooling efficiency. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide an atomizing nozzle for automatically cleaning scale.

[0009] Through the above technical scheme, the fine ejector pin can connect the cleaning support rod with the spray hole cleaning column, so that the cleaning support rod and the atomizing impact plate can be linked. The coolant sprayed through the spray hole position can impact the surface position of the atomizing impact plate.

[0017] Through the above technical solution, the extrusion spring stores energy when the elastic plate is compressed, and the control rope is reset under the action of the extrusion spring after being released. The control rope can be guided and limited by the guide wheel. The arc-shaped guide wheel has a smooth surface, which makes the control rope easy to control and avoids damage to the control rope caused by sharp corners or control difficulties.

[0018] Furthermore, the outer diameter of the liquid spray hole cleaning column is consistent with the inner diameter of the liquid spray hole, and the outer wall of the liquid spray hole cleaning column is slidably connected to the inner wall of the liquid spray hole.

[0019] Through the above technical solution, the outer diameter of the spray hole cleaning column is consistent with the inner diameter of the spray hole, so that the spray hole cleaning column can be rubbed against the inner wall of the spray hole for cleaning, thereby avoiding dirt accumulation and clogging the spray hole.

[0030] 2. When the water temperature is high, you can pull the control rope to move the atomizing impact plate upward, so that the atomization degree is higher, so that the cooling water is fully in contact with the cold air for cooling.

[0045] The atomizing nozzle 12 comprises a nozzle outer tube 1201 , and a liquid spraying hole 1208 is formed through the center of the lower surface of the nozzle outer tube 1201 .

[0046] A fine ejector pin 1207 is arranged at the inner side of the liquid spray hole 1208, and a liquid spray hole cleaning column 1213 is fixedly connected to the bottom of the fine ejector pin 1207, and an atomizing impact plate 1202 is fixedly connected to the bottom of the liquid spray hole cleaning column 1213.

The fine ejector pin 1207 can connect the cleaning support rod 1212 with the liquid spray hole cleaning column 1213, so that the cleaning support rod 1212 and the atomizing impact plate 1202 can be linked, and the coolant sprayed through the liquid spray hole 1208 can impact the surface of the atomizing impact plate 1202, and the water column is atomized under the impact force to accelerate the heat dissipation.

[0047] The bottom of the elastic outer cover 1205 is set to be open, and the inner wall of the elastic outer cover 1205 is slidably connected with an elastic plate 1209 near the opening position, and a linkage rod 1203 set in a "U" shape is fixedly connected between the lower surface of the elastic plate 1209 and the lower surface of the atomizing impact plate 1202. The outer wall of the elastic outer cover 1205 is located below the elastic plate 1209 and is fixedly connected with a number of evenly distributed positioning support plates 1210. The elastic plate 1209 can be controlled by pulling the pull rope 1204 up and down, and the elastic plate 1209 is moved up and down by adjusting the elastic plate 1209. The "U"-shaped linkage rod 1203 can drive the atomizing impact plate 1202, the spray hole cleaning column 1213, the fine ejector pin 1207 and the cleaning support rod 1212 to move up and down, and the spray hole 1208 is cleaned by the spray hole cleaning column 1213.

[0048] A cleaning support rod 1212 is arranged on the inner side of the outer tube 1201 of the nozzle, and the bottom of the cleaning support rod 1212 is fixedly connected to the top of the fine ejector pin 1207, and a plurality of spirally distributed scraping rods 1211 are fixedly connected to the outer wall of the cleaning support rod 1212 from top to bottom, and a plurality of scraping rods 1211 are fixedly connected to a scraping hard plate 1200 at one end away from the cleaning support rod 1212, and the cleaning support rod 1212 can fix and support the plurality of scraping rods 1211, and the scraping hard plate 1200 has the function of supporting and shaping, and the scraping hard plate 1200 is arranged in an arc shape, which can drive the scraping cotton 1215 to slide on the inner wall of the outer tube 1201 of the nozzle.

[0049] The scraping hard plate 1200, the scraping rod 1211 and the cleaning support rod 1212 are all made of polyimide materials, and the thin ejector pin 1207 is made of manganese steel. The scraping hard plate 1200 is fixedly connected with a scraping cotton 1215 at a position away from the scraping rod 1211. The scraping cotton 1215 is made of high-density polyester sponge material. The scraping cotton 1215 is slidably connected to the inner wall of the outer tube 1201 of the nozzle. The polyimide material is light and convenient to be supported by the thin ejector pin 1207. The manganese steel material is hard and has high strength. The scraping cotton 1215 made of high-density polyester sponge material is relatively soft and can rub against the inner wall of the outer tube 1201 of the nozzle, so as to clean impurities adhering to the inner wall of the outer tube 1201 of the nozzle.

[0050] An extrusion spring 1214 is fixedly connected between the upper surface of the elastic plate 1209 and the inner top wall of the elastic outer cover 1205. The extrusion spring 1214 is a compression spring. A guide wheel 1206 arranged in an arc shape is fixedly connected to the middle position of the upper surface of the elastic outer cover 1205 away from the nozzle outer tube 1201. A control pull rope 1204 is fixedly connected to the center position of the upper surface of the elastic plate 1209. The top of the control pull rope 1204 is connected to the top of the elastic outer cover 1205 through sliding. The outer wall of the guide wheel 1206 is slidably connected, and the extrusion spring 1214 stores energy when the elastic plate 1209 is compressed. After the control rope 1204 is released, it is reset under the action of the extrusion spring 1214. The guide wheel 1206 can be used to guide and limit the control rope 1204. The arc-shaped guide wheel 1206 has a smooth surface, which makes the control rope 1204 easier to control and avoids damage to the control rope 1204 due to sharp corners or control difficulties.

[0051] The outer diameter of the spray hole cleaning column 1213 is consistent with the inner diameter of the spray hole 1208, and the outer wall of the spray hole cleaning column 1213 is slidably connected to the inner wall of the spray hole 1208. The outer diameter of the spray hole cleaning column 1213 is consistent with the inner diameter of the spray hole 1208, so that the spray hole cleaning column 1213 can rub against the inner wall of the spray hole 1208 for cleaning, thereby avoiding dirt accumulation and clogging of the spray hole 1208.

[0052] The working principle of this embodiment is as follows: the water to be cooled is poured into each disc-shaped pipe 11 through the liquid supply pipe 5, and the liquid to be cooled in each disc-shaped pipe 11 is sprayed out through the atomizing nozzle 12 and atomized, and the atomized cooling water falls down under the action of gravity, and in the process of falling down, the liquid can be fully cooled by the action of the air flow and the action of the water spraying filler 7, and falls into the liquefaction tank tank body 3 of the liquefaction tank main body 1 for storage, and is discharged through the drainage pipe 4 for use by the condenser, and the atomized cooling water from the atomizing nozzle 12 is discharged from the condenser. The sprayed cooling water will generate steam that moves upwards. The steam will be partially liquefied when passing through the liquefied protrusion 101 of the guide plate body 100 and the inclined baffle at the top of the guide plate body 100. The liquefied cooling water will drip. The remaining small amount of steam will be further intercepted and liquefied when passing through the arc-shaped guide cover 9, and the cooling water will drip down. A small amount of liquefied water vapor and hot air will be discharged from the top of the cooling tower body 6, and the cold air will enter the cooling tower body 6 from the bottom of the cooling tower body 6, and the cooling water will be cooled by the cold air.

[0053] When the cooling water is poured into the atomizing nozzle 12, the cooling water is sprayed out through the spray hole 1208, and the sprayed coolant will impact the surface of the atomizing impact plate 1202, so that the cooling water is atomized and dispersed. The cooling efficiency of the mist cooling water is higher. The atomizing nozzle 12 needs to be cleaned every once in a while. The specific cleaning method is: repeatedly pulling and loosening the collection rope so that the control rope 1204 of each atomizing nozzle 12 position is also pulled or loosened. When the control rope 1204 is pulled, the elastic plate 1209 is pulled up, so that the spring 121 is squeezed. 4 is compressed, the "U"-shaped linkage rod 1203, the atomizing impact plate 1202, the spray hole cleaning column 1213, the fine ejector pin 1207 and the cleaning support rod 1212 move upward, the scraping rod 1211 moves up and down, and the scraping hard plate 1200 drives the scraping cotton 1215 to move up and down, so as to clean the inner side of the nozzle outer tube 1201 to avoid the deposition of scale on the inner wall of the nozzle outer tube 1201, and the spray hole cleaning column 1213 can rub at the position of the spray hole 1208 to avoid the scale blocking the spray hole 1208, thereby ensuring the normal water spraying amount.

[0054] When the water temperature is high, the control rope 1204 can be pulled to move the atomizing impact plate 1202 upward, so that the atomization degree is higher, and the cooling water is fully in contact with the cold air for cooling. At the same time, when the cooling water temperature is low and a low cooling degree is required, the control rope 1204 can be loosened to make the atomizing impact plate 1202 farther away from the spray hole 1208. The lower the atomization degree, the lower the evaporation degree of water, and saves cooling water. The atomization degree can be adjusted according to the water temperature, making the atomizing nozzle 12 more adaptable. After adjustment, the control rope 1204 will fix the collective rope to the position of the column 13.
