Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a water-circulating cooling tower. Background Technology

[0002] A cooling tower is a cooling device that uses water as a circulating refrigerant. It absorbs heat from a system and releases it into the atmosphere. The water absorbs the heat and turns it into hot water. The hot water then comes into contact with the air to exchange heat and produce steam. The steam evaporates and carries away the heat, thus achieving the purpose of heat dissipation. Most existing cooling towers use domestic water resources for cooling, which leads to the waste of water resources.

[0003] Chinese patent application CN202220085753.7 discloses a water-circulating cooling tower. The key technical points of the solution are: by setting an electric hydraulic push rod, spray trough and nozzle, the spray position can be adjusted for cooling according to the usage needs. The structure is simple and reliable, and the spray is more uniform, which is conducive to improving the cooling effect. By using a slide, slider and guide plate, the cooling space inside the tower can also be adjusted according to the usage needs, which is more energy-saving and environmentally friendly, and helps to improve the cooling efficiency.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when cooling the heat exchanger, only domestic water resources can be sprayed onto the surface of the heat exchanger, resulting in a large waste of water resources. At the same time, the large amount of water used leads to high cooling costs. Therefore, a water-circulating cooling tower is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where only domestic water can be sprayed onto the surface of the heat exchanger to cool it down, resulting in significant water waste. This invention proposes a water-circulating cooling tower.

[0007] The effect achieved by the above-mentioned components is that by setting up a water spraying device, rainwater can be collected to cool the heat exchanger, avoiding the situation where only domestic water can be sprayed onto the surface of the heat exchanger when cooling it, which would result in a lot of water waste.

[0008] Preferably, the surface of the collection chamber is fixedly connected to two fixing plates, and each of the two fixing plates has a groove on the side closest to each other, and a filter screen is slidably connected to the surface of the groove of each of the two fixing plates.

[0009] The effect achieved by the above components is that the filter screen can filter rainwater, avoiding the situation where there are too many impurities in the rainwater, and the impurities in the rainwater clog the spray holes after the rainwater flows into the sprinkler pipe, causing the spray holes to malfunction.

[0010] Preferably, an L-shaped plate is fixedly connected to the surface of the fixing plate, a rod is slidably inserted into the L-shaped plate, a handle is fixedly connected to one end of the rod, and two slots are formed on the surface of the filter screen.

[0012] Preferably, the surface of the fixing plate is provided with a groove, and an auxiliary block is fixedly connected to the surface of the groove of the fixing plate.

[0013] The effect achieved by the above-mentioned components is that the auxiliary block facilitates the staff to quickly place the filter screen between the two fixed plates, preventing the staff from having difficulty accurately placing the filter screen between the two fixed plates, which would otherwise result in a long replacement time.

[0014] Preferably, the surfaces of the two fixed plates are provided with a collection device, the collection device including an irregularly shaped collection block, the irregularly shaped collection block being fixedly connected to the surfaces of the two fixed plates, a collection box being slidably connected to the surface of the irregularly shaped collection block, and a handle being fixedly connected to the surface of the collection box.

[0015] The effect achieved by the above components is that by setting up a collection device, impurities in rainwater can be collected, avoiding the situation where impurities in rainwater do not have a suitable container to collect them, causing them to float in the collection chamber for a long time and easily clog the filter screen, thus improving the practicality of the equipment.

[0016] Preferably, both sides of the irregularly shaped collection block are fixedly connected to a fixing block, a rotating rod is rotatably connected to the surface of the fixing block, a limit plate is fixedly connected to the end of the rotating rod away from the fixing block, and two L-shaped blocks are fixedly connected to the surface of the collection box.

[0017] The aforementioned components achieve the following effect: they can fix the collection box in place, preventing the collection box from shaking and slipping out, thus preventing the collection box from effectively collecting impurities.

[0018] Preferably, a round rod is slidably inserted into the fixing block, and a round hole is formed on the surface of the limiting plate.

[0019] The aforementioned components achieve the following effect: they can fix the limiting plate in place, preventing the limiting plate from shaking and colliding with the collection box when the staff moves the collection box, thus avoiding damage to the limiting plate.

[0031] Reference Figure 1 and Figure 2 As shown, this utility model provides a technical solution: a water-circulating cooling tower, including a cooling tower body 1, a heat exchanger 2 installed on the surface of the cooling tower body 1, and a water spraying device 3 on the surface of the cooling tower body 1. By setting the water spraying device 3, rainwater can be collected to cool the heat exchanger 2, avoiding the situation where only domestic water can be sprayed onto the surface of the heat exchanger 2 to cool it, thus avoiding the waste of water resources. This not only improves the utilization rate of water resources but also reduces cooling costs. The surfaces of the two fixed plates 305 are equipped with collection devices 4, which can collect impurities in the rainwater. This avoids the situation where impurities in the rainwater do not have suitable containers for collection, causing them to float in the collection chamber 301 for a long time and easily clog the filter screen 306, thus improving the practicality of the equipment.

[0032] The specific setup and function of the water spraying device 3 and the collection device 4 will be explained below.

[0033] Reference Figure 3 , Figure 4 and Figure 5As shown in this embodiment: the water spraying device 3 includes a collection chamber 301, which is fixedly connected to the surface of the cooling tower body 1. Water outlet holes are provided on the surface of the collection chamber 301. A connecting pipe 302 is fixedly connected to the surface of the collection chamber 301. A spray pipe 303 is fixedly connected to the end of the connecting pipe 302 away from the collection chamber 301. Several spray holes 304 are provided on the arc surface of the spray pipe 303. Two fixing plates 305 are fixedly connected to the surface of the collection chamber 301. Sliding grooves are provided on the sides of the two fixing plates 305 that are close to each other. Filter screens 306 are slidably connected to the surfaces of the sliding grooves of the two fixing plates 305. When it rains, the collection chamber 301 can collect and store rainwater. When the staff needs to cool the heat exchanger 2... Rainwater first passes through filter screen 306, then flows into connecting pipe 302 through the outlet of collection chamber 301, subsequently enters spray pipe 303, and finally flows onto the surface of heat exchanger 2 through spray hole 304, thereby cooling the heat exchanger 2. Filter screen 306 effectively filters rainwater, preventing impurities from clogging the spray holes 304 after the rainwater flows into spray pipe 303, thus preventing the spray holes 304 from functioning properly. An L-shaped plate 307 is fixedly connected to the surface of fixing plate 305, and a rod 308 is slidably inserted into the L-shaped plate 307. One end of the rod 308 is fixedly connected to a handle 309. Two slots are provided on the surface of filter screen 306. When filter screen 306 has been used for a long time... After the filter screen 306 is damaged, it can be replaced to prevent a decrease in its filtration efficiency. At this time, the operator can drain the rainwater from the collection chamber 301, pull the handle 309, and the handle 309 will move the insertion rod 308. When the insertion rod 308 is completely disengaged from the surface of the slot of the filter screen 306, the insertion rod 308 will release its fixation to the filter screen 306. Move the filter screen 306, and it will slide on the surface of the groove of the fixing plate 305 until the filter screen 306 is completely detached from the surface of the fixing plate 305. At this point, the operator can place a new filter screen 306 into the fixing plate 305. When the new filter screen 306 is returned to its original position, push the handle 309, and the handle 309 will move the insertion rod 308 until the insertion rod 308 is inserted into the slot. The surface of the filter 306 slot facilitates quick and easy replacement of the filter 306 by operators. This simple and convenient operation improves replacement efficiency. The surface of the fixing plate 305 has a groove, and an auxiliary block 310 is fixedly connected to the surface of the groove. When an operator needs to place a new filter 306 between the two fixing plates 305, moving the filter 306 causes it to first contact the auxiliary block 310. Continuing to move the filter 306 causes it to move along the surface of the auxiliary block 310 until it reaches the center of the two fixing plates 305. The auxiliary block 310 effectively facilitates quick and easy placement of the filter 306 between the two fixing plates 305.To prevent staff from having difficulty accurately placing the filter screen 306 between the two fixing plates 305, thus avoiding a prolonged replacement time,

[0034] Reference Figure 6 and Figure 7 As shown, specifically, the collection device 4 includes an irregularly shaped collection block 41, which is fixedly connected to the surfaces of two fixed plates 305. A collection box 42 is slidably connected to the surface of the irregularly shaped collection block 41, and a handle 43 is fixedly connected to the surface of the collection box 42. Fixed blocks 44 are fixedly connected to both sides of the irregularly shaped collection block 41, and a rotating rod 45 is rotatably connected to the surface of the fixed blocks 44. A limit plate 46 is fixedly connected to the end of the rotating rod 45 away from the fixed blocks 44. Two L-shaped blocks 47 are fixedly connected to the surface of the collection box 42. When impurities in the rainwater flow together with the rainwater... When the rainwater moves near the filter screen 306, it flows out through the filter screen 306. Impurities hit the filter screen 306 and are blocked. Then, the impurities move downwards and fall into the collection box 42, thus completing the collection of impurities in the rainwater. When there are many impurities in the collection box 42, the staff can clean the impurities in the collection box 42. Rotate the limiting plate 46, and the limiting plate 46 drives the rotating rod 45 to rotate. When the limiting plate 46 is completely separated from the surface of the collection box 42, the limiting plate 46 releases the fixing of the collection box 42. Move the handle 43, and the handle 43 drives the collection box 42 to move. When the collection box 42 is completely detached from the surface of the irregularly shaped collection block 41, the staff can clean the impurities from the collection box 42. After cleaning, the collection box 42 is returned to its original position, and the limiting plate 46 is rotated. When the limiting plate 46 rotates to the surface of the L-shaped block 47, the limiting plate 46 fixes the collection box 42, achieving the effect of fixing the collection box 42 and preventing the collection box 42 from shaking and slipping out, which would prevent the collection box 42 from effectively collecting impurities. A round rod 48 is slidably inserted into the fixing block 44, and a round hole is opened on the surface of the limiting plate 46. When the staff needs to remove the collection box 42, they rotate the limiting plate 46. When the limiting plate 46 is rotated to the appropriate position, the circular hole of the limiting plate 46 is located in front of the circular rod 48. The circular rod 48 is moved, and when the circular rod 48 is inserted into the surface of the circular hole of the limiting plate 46, the circular rod 48 fixes the limiting plate 46. At this time, the staff can move the collection box 42, which achieves the effect of fixing the limiting plate 46 and avoids the limiting plate 46 from shaking and colliding with the collection box 42 when the staff moves the collection box 42, which would easily damage the limiting plate 46.

[0035] Working principle: When it rains, the collection chamber 301 collects and stores rainwater. When the heat exchanger 2 needs cooling, the rainwater first passes through the filter screen 306, then flows through the outlet of the collection chamber 301 into the connecting pipe 302, then into the spray pipe 303, and finally flows through the spray hole 304 onto the surface of the heat exchanger 2, thereby cooling the heat exchanger 2. When the filter screen 306 is damaged after long-term use, it can be replaced to prevent a decrease in its filtration efficiency. At this time, the staff can drain the rainwater from the collection chamber 301, pull the handle 309, and the handle 309 moves the insertion rod 308. When the insertion rod 308 is completely disengaged from the surface of the slot of the filter screen 306, the insertion rod 308 releases the fixation of the filter screen 306, and the filter screen 306 moves. The filter screen 306 slides on the surface of the fixed plate 305 until it is completely detached from the surface of the fixed plate 305. At this time, the operator can place the new filter screen 306 between the two fixed plates 305 and move the filter screen 306. The filter screen 306 first contacts the auxiliary block 310, and then the operator continues to move the filter screen 306. The filter screen 306 will move along the surface of the auxiliary block 310 until it moves to the middle of the two fixed plates 305. When the new filter screen 306 is put back in its original position, the handle 309 is pushed. The handle 309 drives the insertion rod 308 to move until the insertion rod 308 is inserted into the surface of the slot of the filter screen 306. At this time, rainwater can be collected to cool the heat exchanger 2, avoiding the situation where only domestic water can be sprayed onto the surface of the heat exchanger 2 when cooling the heat exchanger 2, which would result in a lot of water waste.

[0036] When impurities in the rainwater flow to the vicinity of filter screen 306 along with the rainwater, the rainwater flows out through filter screen 306, while the impurities are blocked by filter screen 306 and then move downwards and fall into collection box 42, thus completing the collection of impurities in the rainwater. When there are many impurities in collection box 42, the staff can clean the impurities in collection box 42. Rotating the limiting plate 46 causes the rotating rod 45 to rotate. When the limiting plate 46 rotates to the appropriate position, the circular hole of the limiting plate 46 is directly in front of the circular rod 48. Moving the circular rod 48, when the circular rod 48 is inserted into the surface of the circular hole of the limiting plate 46, the circular rod 48 fixes the limiting plate 46. Move handle 43 to move collection box 42. When collection box 42 is completely detached from the surface of irregular collection block 41, the staff can clean the impurities in collection box 42. After cleaning, put collection box 42 back in place and pull round rod 48. When round rod 48 is detached from the surface of round hole of limiting plate 46, rotate limiting plate 46. When limiting plate 46 rotates to the surface of L-shaped block 47, limiting plate 46 fixes collection box 42. At this time, the effect of collecting impurities in rainwater is achieved, avoiding the situation where impurities in rainwater do not have a suitable container for collection, causing impurities to float in collection chamber 301 for a long time, which can easily cause impurities to clog filter screen 306.
