Description

Technical Field

[0001] The utility model relates to the technical field of condenser microatomization water replenishment, in particular to a condenser microatomization water replenishment device. Background Technique

[0002] A condenser is a heat exchanger, and its main function is to condense steam into water. According to different cooling media, condensers are mainly divided into two types: water-cooled condensers and air-cooled condensers. In industrial fields such as thermal power plants, water is usually used as the cooling medium in condensers, and steam is condensed into water through heat exchange.

[0003] According to CN201720660858.X disclosed in the Chinese patent, in this application document, the water atomization effect is better, and the atomized water is more likely to vaporize with a large amount of heat after contacting the condenser, and the heat exchange efficiency is high; the nozzle is convenient to clean and not easy to block;

[0004] Although the atomized water in the application document is more likely to vaporize with a large amount of heat after contacting the condenser and can effectively deal with the problem of low heat-work conversion efficiency, however, during use, when directly replenishing water to the condenser, the water flow may not fully contact the steam or high-temperature medium, resulting in a reduction in heat exchange efficiency, and direct water replenishment may cause uneven distribution of the water flow in the condenser tubes, resulting in local overheating or uneven cooling, which will affect the stability and reliability of the entire system and may even cause failures. For this reason, we propose a condenser microatomization water replenishment device. Content of the Utility Model

Four groups of support legs are fixedly connected to the bottom of the condenser tubes. A hot well is fixedly connected between the four groups of support legs at a position corresponding to the bottom of the condenser tubes. Two groups of heat transfer tubes are welded to both ends of the condenser tubes. A water replenishment pipe is welded to the outside of one of the heat transfer tubes at a position corresponding to one end of the condenser tubes. One end of the water replenishment pipe corresponding to the inner wall of the condenser tube is fixedly connected with a three-way pipe. Two groups of pipelines are fixedly connected to the outside of the three-way pipe. Twenty-four mounting holes are opened on both sides of the two groups of pipelines. Nozzles are welded to the inner walls of the twenty-four mounting holes. A water replenishment regulating valve is fixedly connected to the outside of the water replenishment pipe far from the condenser tube. It further includes:

[0009] A large-angle diffusion atomization structure arranged at the top of the nozzle, which is used to change the direct make-up water inside the condenser tube into atomized make-up water;

[0010] An angle adjustment structure arranged at the top of the nozzle, which is used to adjust the make-up water direction.

[0011] Preferably, the twenty-four nozzles are inclined obliquely upward at an angle of 45 degrees, and the angle between two rows of nozzles is 90 degrees.

[0012] Preferably, a conical column is welded to the inner wall of the nozzle, and the inside of the conical column is hollow, and the bottom diameter of the conical column is smaller than the top diameter, and a lid is fixedly connected to the top of the nozzle.

[0013] Preferably, a spring is fixedly connected to the bottom of the lid, the bottom of the spring is fixedly connected to a conical vibration block, and the outside of the conical vibration block is movably connected to the inner wall of the conical column.

[0014] Preferably, the angle adjustment structure includes a sleeve, a water outlet hole, a threaded barrel and a movable ball. Five water outlet holes are opened at the top of the lid, and threaded barrels are fixedly connected to the tops of the five water outlet holes. The outside of the threaded barrel is threadedly sleeved with a sleeve, and a movable ball is clamped at the top of the sleeve.

[0015] Preferably, the large-angle diffusion atomization structure includes a threaded fixing block, a fan-shaped water outlet groove, a connecting block and a spiral nozzle.

The outside of the threaded fixing block is threadedly connected to the connecting block, and a spiral nozzle is fixedly connected to the top of the connecting block.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a condenser micro-atomization make-up water device, which has the following beneficial effects:

[0018] 1. When the large-angle diffusion atomization structure arranged in the condenser micro-atomization make-up water device is working, water is sprayed out from the fan-shaped water outlet groove at the top of the threaded fixing block. Subsequently, this part of the water flow enters the spiral nozzle part and is guided by the spiral channel, generating a rotational effect. The rotational movement makes the water flow further disperse and forms a wider and more uniform fan-shaped spray at the spray outlet. This design combines the wide coverage of the fan-shaped nozzle and the high-efficiency atomization effect of the spiral nozzle, and can achieve uniform and efficient spraying or atomization in a larger range. This design enables the water flow ejected from the nozzle to form a large-area fan-shaped atomization area, thereby increasing the contact area between water and steam or high-temperature medium and improving the heat exchange efficiency.

[0019] Large-angle diffusion not only helps reduce the accumulation and scouring of water flow inside the condenser tubes, but also enables the atomized water droplets to be more evenly distributed on the tube walls, reducing phenomena such as local overheating or uneven cooling.

[0020] 2. For this condenser micro-atomization water replenishment device, direct water replenishment often leads to the formation of scouring and accumulation of water flow inside the condenser tubes, affecting the heat exchange efficiency and potentially increasing the formation of water scale. Atomized water replenishment can avoid these problems, enabling the water flow to be evenly distributed inside the condenser tubes in the form of finer particles. Atomized water replenishment can also improve the utilization rate of cooling water and reduce water resource waste. Since the contact area between the atomized water droplets and steam increases, the same amount of water can carry away more heat, thereby reducing the consumption of cooling water.

[0021] 3. For this condenser micro-atomization water replenishment device, the design of the nozzle with a 45-degree upward inclination and the 90-degree angle arrangement between two rows of nozzles ensures the uniform distribution and coverage of the replenished water or atomized water vapor inside the condenser tubes. This design helps reduce phenomena such as local overheating or uneven cooling and improves the overall heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-6 , a condenser microatomization water replenishment device, which includes a condenser tube 1, support legs 2, heat transfer tubes 3, a hot well 4, a water replenishment pipe 5, a water replenishment regulating valve 6, pipes 7, a tee pipe 8, mounting holes 9 and nozzles 10. Four groups of support legs 2 are fixedly connected to the bottom of the condenser tube 1. A hot well 4 is fixedly connected between the four groups of support legs 2 at a position corresponding to the bottom of the condenser tube 1. Two groups of heat transfer tubes 3 are welded to both ends of the condenser tube 1. A water replenishment pipe 5 is welded to the outside of one of the heat transfer tubes 3 at a position corresponding to one end of the condenser tube 1. A tee pipe 8 is fixedly connected to the end of the water replenishment pipe 5 corresponding to the inner wall of the condenser tube 1. Two groups of pipes 7 are fixedly connected to the outside of the tee pipe 8. Twenty-four mounting holes 9 are opened on both sides of the two groups of pipes 7. Nozzles 10 are welded to the inner walls of the twenty-four mounting holes 9. A water replenishment regulating valve 6 is fixedly connected to the outside of the water replenishment pipe 5 away from the condenser tube 1. It further includes:

[0031] A large-angle diffusion atomization structure arranged at the top of the nozzle 10, which is used to change the direct water replenishment inside the condenser tube 1 into atomized water replenishment;

[0032] An angle adjustment structure arranged at the top of the nozzle 10, which is used to adjust the water replenishment direction. The operator opens the water replenishment regulating valve 6 to allow external water sources to enter the condenser system through the water replenishment pipe 5. After the water flows in from the water replenishment pipe 5, it first encounters the tee pipe 8. The tee pipe 8 evenly distributes the water flow into the two pipes 7. These two pipes extend to both sides respectively to provide water sources for the nozzles 10. The water enters the mounting holes 9 through the pipes 7 and finally flows into the nozzles 10.

[0033] Furthermore, the twenty-four nozzles 10 are inclined obliquely upward at an angle of 45 degrees, and the angle between the two rows of nozzles 10 is 90 degrees. This design enables the water flow or atomized water vapor ejected from the nozzles 10 to diffuse at a larger angle, thereby forming a more uniform spraying or atomization effect inside the condenser tube 1. The setting of the nozzles inclined obliquely upward at an angle of 45 degrees enables the water flow or atomized water vapor to more fully cover the internal space of the condenser tube 1 and improve the efficiency of water replenishment or cooling.

[0034] Furthermore, a conical column 11 is welded to the inner wall of the nozzle 10, and the interior of the conical column 11 is hollow, and the bottom diameter of the conical column 11 is smaller than the top diameter. A cover 12 is fixedly connected to the top of the nozzle 10. Inside the nozzle 10, the conical column 11 and the conical vibration block 13 work together to form an atomization effect. When water flows through the conical column 11, since the bottom diameter of the conical column 11 is smaller than the top diameter, the water flow velocity increases and the pressure decreases, forming a certain negative pressure effect.

[0035] Furthermore, a spring 14 is fixedly connected to the bottom of the cover 12, a conical vibration block 13 is fixedly connected to the bottom of the spring 14, and the outer side of the conical vibration block 13 is movably connected to the inner wall of the conical column 11. At this time, the conical vibration block 13 is tightly attached to the inner wall of the conical column 11 under the action of the spring 14, but with the impact of the water flow, the conical vibration block 13 will vibrate slightly to further refine the water flow.

[0036] Furthermore, the angle adjustment structure includes a sleeve 15, a water outlet hole 16, a threaded cylinder 17 and a movable ball 18. Five groups of water outlet holes 16 are opened on the top of the cover 12, and the tops of the five groups of water outlet holes 16 are fixedly connected with a threaded cylinder 17. The outer thread of the threaded cylinder 17 is threadedly sleeved with the sleeve 15, and the top of the sleeve 15 is clamped with a movable ball 18. The water outlet direction of the nozzle 10 can be adjusted by adjusting the angle structure. Specifically, the movable ball 18 can be moved on the top of the sleeve 15 by bending the spiral nozzle 22, thereby changing the position of the movable ball 18 and changing the spray direction of the water mist. This design allows the spray angle of the water mist to be flexibly adjusted according to the actual situation inside the condenser and the cooling requirements.

[0037] Furthermore, the large-angle diffusion atomization structure includes a threaded fixing block 19, a fan-shaped water outlet groove 20, a connecting block 21 and a spiral nozzle 22. The top of the movable ball 18 is fixedly connected to the threaded fixing block 19, and the top of the threaded fixing block 19 is provided with a fan-shaped water outlet groove 20. The outer side of the threaded fixing block 19 is threadedly connected to the connecting block 21, and the top of the connecting block 21 is fixedly connected to the spiral nozzle 22. Water is sprayed out from the fan-shaped water outlet groove 20 at the top of the threaded fixing block 19. Subsequently, this part of the water flow enters the spiral nozzle 22 part, and is guided by the spiral channel to produce a rotation effect. The rotational motion further disperses the water flow and forms a wider and more uniform fan-shaped spray when it is sprayed. This design combines the wide coverage of the fan-shaped nozzle and the efficient atomization effect of the spiral nozzle, and can achieve uniform and efficient spraying or atomization over a larger range.

[0038] Working principle:

[0039] The operator opens the water supply regulating valve 6 to allow external water to enter the condenser system through the water supply pipe 5. After the water flows in from the water supply pipe 5, it first encounters the tee pipe 8. The tee pipe 8 evenly distributes the water flow to the two pipes 7. The two pipes extend to both sides to provide water for the nozzle 10. The water enters the installation hole 9 through the pipe 7 and finally flows into the nozzle 10. Inside the nozzle 10, the conical column 11 and the conical vibration block 13 work together to form an atomization effect. When water flows through the conical column 11, since the bottom diameter of the conical column 11 is smaller than the top diameter, the water flow speed increases and the pressure decreases, forming a certain negative pressure effect. At this time, the conical vibration block 13 is tightly attached to the inner wall of the conical column 11 under the action of the spring 14, but with the impact of the water flow, the conical vibration block 13 will vibrate slightly to further refine the water flow; the water is sprayed out from the fan-shaped water outlet 20 at the top of the threaded fixing block 19. The fan-shaped water outlet 20 itself can spray the liquid at a fan-shaped angle. Go, covering a larger area, and then this part of the water flow enters the spiral nozzle 22 part, and is guided by the spiral channel to produce a rotation effect. The rotation motion makes the water flow further dispersed and forms a wider and more uniform fan-shaped spray when it is sprayed out. This design combines the wide coverage of the fan-shaped nozzle and the efficient atomization effect of the spiral nozzle, and can achieve uniform and efficient spraying or atomization in a larger range. The combination of the two can further enhance the uniformity and coverage of the spray on the basis of maintaining the fan-shaped spray; the water outlet direction of the nozzle 10 can be adjusted by adjusting the angle structure. Specifically, by bending the spiral nozzle 22, the movable ball 18 can be moved on the top of the sleeve 15, changing the position of the movable ball 18, thereby changing the spray direction of the water mist. This design allows the spray angle of the water mist to be flexibly adjusted according to the actual situation inside the condenser and the cooling requirements; the atomized water mist is in full contact with the high-temperature steam in the condenser tube 1. Since the surface area of the water mist is greatly increased, the heat exchange efficiency is significantly improved, and the water mist evaporates quickly and absorbs the heat in the steam, thereby reducing the steam temperature and promoting the condensation process; the condensed water falls into the hot well 4 and continues to be used as part of the circulating water;

[0040] In summary, the condenser system significantly improves the heat exchange efficiency and enhances the cooling effect through precise water replenishment atomization and direction adjustment design.
