Description

Technical Field

[0001] The present application relates to the technical field of cooling towers, and particularly to a water distributor and a cooling tower. Background Art

[0002] Cooling towers are an important part of the circulating water system in life and industrial and agricultural production. Cooling towers achieve the circulating cooling of water by exchanging heat between the circulating water and air. The water distributor is an important component of the cooling tower. The water to be cooled flows into the cavity of the cooling tower through the water distributor, so that the water exchanges heat with the air in the cavity of the cooling tower and cools down. However, for traditional water distributors, when water flows out of the water distributor, there is usually a defect that the water is unevenly distributed in the cavity of the cooling tower, which affects the heat dissipation effect of the water and ultimately affects the cooling effect of the cooling tower on the circulating water. Summary of the Invention

[0003] One technical problem solved by the present application is how to improve the uniformity of water flow distribution of the water distributor.

[0004] A water distributor is used to be arranged in the inner cavity of a cooling tower. The water distributor includes a housing. The housing is conical, and the vertex of the housing is located below the bottom surface of the housing. The housing encloses a buffer cavity. The housing is provided with water distribution holes, and the water distribution holes communicate the buffer cavity and the inner cavity of the cooling tower. The extending direction of the water distribution holes is the same as the extending direction of the tangent line of the outer side surface of the housing.

[0005] In one embodiment, the diameter of the bottom surface of the housing is 1 / 3 to 1 / 2 of the diameter of the inner cavity of the cooling tower.

[0006] In one embodiment, it further includes a water inlet pipe. The water inlet pipe is located in the buffer cavity. One end of the water inlet pipe is connected to the bottom surface of the housing, and the other end of the water inlet pipe keeps a set distance from the vertex of the housing.

[0007] In one embodiment, it further includes a plurality of vertical members and a plurality of horizontal members. The vertical members and the horizontal members are perpendicular to each other. The vertical members extend along the axial direction of the housing. The plurality of horizontal members are arranged at intervals along the axial direction of the housing. The two horizontal members located at the outermost ends in the axial direction of the housing are both connected to the water inlet pipe. The length of the horizontal member closest to the bottom surface of the housing is the longest. The plurality of vertical members are arranged at intervals along the radial direction of the housing, and the vertical members are connected between any two adjacent horizontal members, so that the horizontal members and the vertical members are connected to form a stepped structure.

[0008] In one embodiment, the water inlet pipe is coaxially arranged with the housing.

[0009] In one embodiment, the housing is slidably disposed along the axial direction of the housing in the inner cavity of the cooling tower. When the water flow rate entering the housing increases, the housing moves upward; when the water flow rate entering the housing decreases, the housing moves downward.

[0010] In one embodiment, when the water flow rate in the housing is less than 50% of the rated flow rate, the housing moves to the lowest point. When the water flow rate in the housing increases to 100% of the rated flow rate, the housing moves to the highest point.

[0011] In one embodiment, the housing is made of a corrosion-resistant material.

[0012] In one embodiment, the number of the water distribution holes is multiple, and the multiple water distribution holes are spaced along the axial direction and the circumferential direction of the housing.

[0013] A cooling tower includes a tower body, a fan, a circulation pipe, a storage member, and the water distributor described in any one of the above. An air inlet hole is provided at the bottom of the tower body, and the air inlet hole is communicated with the inner cavity of the tower body. The fan is disposed at the top of the tower body. The water distributor is located between the fan and the air inlet hole. The storage member is received in the inner cavity of the tower body and is located below the water distributor. One end of the circulation pipe is connected to the water distributor, and the other end of the circulation pipe is connected to the storage member.

[0014] A technical effect of an embodiment of the present application is that: in view of the fact that the vertex of the housing is located below the bottom surface of the housing, the housing forms an inverted conical shape, and the extending direction of the water distribution hole is the same as the extending direction of the tangent line of the outer side surface of the housing. In this way, the water in the buffer cavity is sprayed along the periphery of the housing, so that the water flowing out of the water distribution hole covers the inner cavity of the entire tower body along the radial direction of the housing, thereby improving the uniformity of the water distribution in the inner cavity, that is, improving the uniformity of the water flow distribution of the water distributor. In this way, the contact area between the water flowing out of the water distribution hole and the air in the inner cavity can be increased, so that sufficient heat exchange occurs between the gas and the water flowing out of the water distribution hole, ensuring that the gas in the inner cavity fully absorbs the heat of the high-temperature water, improving the heat dissipation efficiency of the high-temperature water, and thus ensuring that the high-temperature water is quickly converted into the low-temperature water that meets the requirements. Since the housing forms an inverted conical shape, the housing can play a good guiding role for the gas in the inner cavity, thereby reducing the flow resistance of the gas flowing through the water distributor in the inner cavity, reducing the residence time of the gas in the inner cavity, and thus improving the heat exchange efficiency between the gas and the water, that is, improving the heat dissipation effect of the gas on the high-temperature water.

[0025] Refer to Figure 1 , Figure 2 and Figure 3, a cooling tower 10 provided by an embodiment of the present application includes a tower body 11, a fan 13, a circulation pipe 14, a storage member 15, and a water distributor 16. The tower body 11 can be generally a cylindrical structure. An air inlet hole 17 is provided at the bottom of the tower body 11, so that the air inlet hole 17 communicates the outside and the inner cavity 12 of the tower body 11, that is, the outside air can enter the inner cavity 12 of the tower body 11 from the bottom through the air inlet hole 17. The fan 13 is arranged at the top of the tower body 11. When the fan 13 works, the outside air enters the inner cavity 12 of the tower body 11 from the bottom through the air inlet hole 17, and flows out from the top of the tower body 11 under the action of the fan 13. Therefore, the gas flows in the inner cavity 12 of the tower body 11 along the path from bottom to top. The water distributor 16 is arranged in the inner cavity 12 of the tower body 11. The water distributor 16 is located between the fan 13 and the air inlet hole 17, that is, the water distributor 16 is located below the fan 13 and above the air inlet hole 17. The storage member 15 is located in the inner cavity 12 of the tower body 11, and the storage member 15 can be located below the water distributor 16. One end (i.e., the upper end) of the circulation pipe 14 is connected to the water distributor 16, and the other end (i.e., the lower end) of the circulation pipe 14 is connected to the storage member 15. The water in the circulation pipe 14 can flow into the water distributor 16 from the upper end of the circulation pipe 14. The water in the water distributor 16 can flow into the storage member 15, and the water in the storage member 15 can flow into the circulation pipe 14 from the lower end of the circulation pipe 14. Therefore, the water can flow cyclically between the circulation pipe 14, the water distributor 16, and the storage member 15. It can be understood that the water flows in the inner cavity 12 of the tower body 11 in the direction from top to bottom.

[0026] Referring to Figure 1 , Figure 2 and Figure 3 , when the cooling tower 10 works, the high-temperature water to be cooled flows into the water distributor 16 from the upper end of the circulation pipe 14, and then the water will flow out of the water distributor 16. During the process of the water flowing out of the water distributor 16, the fan 13 works simultaneously, so that the outside air enters the inner cavity 12 of the tower body 11 from the air inlet hole 17. In view of the fact that the water flows from top to bottom and the gas flows from bottom to top, the outside air will generate heat exchange with the water flowing out of the water distributor 16 in the inner cavity 12 of the tower body 11, so that the gas absorbs the heat of the water flowing out of the water distributor 16. The gas after absorbing the heat will be discharged from the top of the tower body 11. Therefore, the outside air can continuously enter the inner cavity 12 of the tower body 11 from the bottom, so as to absorb heat from the water flowing out of the water distributor 16 to cool it down. The gas after absorbing the heat can continuously flow out from the top, so that there is enough gas in the inner cavity 12 of the tower body 11 to cool the water flowing out of the water distributor 16. The cooled low-temperature water will further flow into the storage member 15 and flow out of the circulation pipe 14 through the storage member 15, so as to realize the cyclic cooling and cooling of the water by the cooling tower 10.

[0027] It can be understood that after the cooled low-temperature water flows out of the circulation pipe 14, the low-temperature water can be used for production and life. After the low-temperature water absorbs heat and forms high-temperature water during production and life, the high-temperature water will enter the water distributor 16 from the circulation pipe 14 and flow out of the water distributor 16, so that the cooling tower 10 cools the high-temperature water to convert it into low-temperature water. Therefore, through the action of the cooling tower 10, the high-temperature water generated during the production and life processes can be circulated and processed to achieve cooling, so that the low-temperature water can well meet the needs of production and life, that is, the cooling tower 10 can continuously provide low-temperature water for production and life.

[0028] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the water distributor 16 includes a housing 100. The housing 100 is conical, and the vertex of the housing 100 is located below the bottom surface of the housing 100, so that the conical shape is inverted. The housing 100 encloses a buffer chamber 110. The housing 100 is provided with water distribution holes 120. The water distribution holes 120 communicate the buffer chamber 110 and the inner cavity 12 of the cooling tower 10. The extending direction of the water distribution holes 120 is the same as the extending direction of the tangent line of the outer side surface of the housing 100. After the water in the circulation pipe 14 flows into the buffer chamber 110 of the housing 100, the liquid in the buffer chamber 110 will flow into the inner cavity 12 of the tower body 11 through the water distribution holes 120. In this way, the high-temperature water flowing out of the water distribution holes 120 is cooled by the gas in the inner cavity 12 and converted into low-temperature water. In view of the fact that the housing 100 forms an inverted conical shape, and the extending direction of the water distribution holes 120 is the same as the extending direction of the tangent line of the outer side surface of the housing 100. In this way, the water in the buffer chamber 110 is sprayed along the periphery of the housing 100, so that the water flowing out of the water distribution holes 120 covers the entire inner cavity 12 of the tower body 11 along the radial direction of the housing 100. In this way, the contact area between the water flowing out of the water distribution holes 120 and the air in the inner cavity 12 can be increased, so that sufficient heat exchange occurs between the gas and the water flowing out of the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water and improving the heat dissipation efficiency of the high-temperature water, so as to ensure that the high-temperature water is quickly converted into low-temperature water that meets the requirements. Since the housing 100 forms an inverted conical shape, the housing 100 can play a good guiding role for the gas, thereby reducing the flow resistance of the gas flowing through the water distributor 16 in the inner cavity 12 and reducing the residence time of the gas in the inner cavity 12, so that enough cold air can be supplemented through the air inlet holes 17 in the inner cavity per unit time, and the fan 13 can also discharge enough hot air from the inner cavity 12 per unit time, thereby improving the heat exchange efficiency between the gas and the water, that is, improving the heat dissipation effect of the gas on the high-temperature water.

[0029] Refer to Figure 1 , Figure 2 and Figure 3, in some embodiments, the diameter d of the bottom surface of the housing 100 is 1 / 3 to 1 / 2 of the diameter D of the inner cavity 12 of the cooling tower 10. For example, the diameter d of the bottom surface of the housing 100 is 1 / 3 or 1 / 2 of the diameter D of the inner cavity 12 of the cooling tower 10, etc. By designing the diameter d of the bottom surface of the housing 100 to be 1 / 3 to 1 / 2 of the diameter D of the inner cavity 12 of the cooling tower 10, when the liquid in the buffer cavity 110 is discharged from the water distribution holes 120 into the inner cavity 12 of the tower body 11, it can also make the water discharged from the water distribution holes 120 cover the entire inner cavity 12 of the tower body 11 along the radial direction of the housing 100. In this way, the contact area between the water flowing out from the water distribution holes 120 and the air in the inner cavity 12 can be increased, enabling sufficient heat exchange between the gas and the water flowing out from the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water, improving the heat dissipation efficiency of the high-temperature water, and thus ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements.

[0030] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the number of the water distribution holes 120 is multiple. The multiple water distribution holes 120 can be arranged at intervals along the axial direction of the housing 100, or can be arranged at intervals along the circumferential direction of the housing 100. For example, first, the multiple water distribution holes 120 are arranged at intervals along the circumferential direction of the housing 100 to form a row, and then multiple rows can be arranged at intervals along the axial direction of the housing 100, so that there are enough water distribution holes 120 distributed on the housing 100. Therefore, when the water in the water distribution holes 120 flows into the inner cavity 12 of the tower body 11, it makes the water flowing out from the water distribution holes 120 cover the entire inner cavity 12 of the tower body 11 along the radial direction of the housing 100. In this way, the contact area between the water flowing out from the water distribution holes 120 and the air in the inner cavity 12 can be increased, enabling sufficient heat exchange between the gas and the water flowing out from the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water, improving the heat dissipation efficiency of the high-temperature water, and thus ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements.

[0031] Refer to Figure 1 , Figure 2 and Figure 3, in some embodiments, the water distributor 16 further includes a water inlet pipe 200. The water inlet pipe 200 is located in the buffer chamber 110. One end of the water inlet pipe 200 is connected to the bottom surface of the housing 100, and the other end of the water inlet pipe 200 maintains a set distance from the vertex of the housing 100. The lumen of the circulation pipe 14 can be communicated with the lumen of the water inlet pipe 200, and the lumen of the water inlet pipe 200 is communicated with the buffer chamber 110. During operation, the water in the circulation pipe 14 can enter the water inlet pipe 200 from the upper end of the water inlet pipe 200, and then the water will flow into the buffer chamber 110 from the lower end of the water inlet pipe 200. Then the water will flow from the buffer chamber 110 into the inner cavity 12 of the tower body 11 through the water distribution holes 120. By providing the water inlet pipe 200, the water flowing out of the water inlet pipe 200 can fill the buffer chamber 110 of the housing 100 from bottom to top, ensuring that the water in the buffer chamber 110 covers all the water distribution holes 120 in the circumferential direction of the housing 100, avoiding the water flowing out of the circulation pipe 14 only covering some of the water distribution holes 120 in the circumferential direction of the housing 100, ensuring that the water flowing out of the water distribution holes 120 is evenly distributed in the inner cavity 12 of the tower body 11, thereby increasing the contact area between the water flowing out of the water distribution holes 120 and the air in the inner cavity 12, enabling sufficient heat exchange between the gas and the water flowing out of the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water, improving the heat dissipation efficiency of the high-temperature water, and thus ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements.

[0032] Refer to Figure 1 , Figure 2 and Figure 3 , in some embodiments, the water inlet pipe 200 is coaxially arranged with the housing 100. In this way, on the one hand, the design and manufacturing costs of the water distributor 16 can be reduced, and on the other hand, it can further ensure that the water in the buffer chamber 110 covers all the water replenishing holes in the circumferential direction of the housing 100, thereby further improving the heat dissipation efficiency of the high-temperature water and ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements.

[0033] Refer to Figure 1 , Figure 2 and Figure 3, in some embodiments, the water distributor 16 further includes a plurality of vertical members 310 and a plurality of horizontal members 320. The vertical members 310 and the horizontal members 320 are perpendicular to each other. The vertical members 310 extend along the axial direction of the housing 100, that is, the vertical members 310 extend in the vertical direction, and the horizontal members 320 extend in the horizontal direction. The plurality of horizontal members 320 are arranged at intervals along the axial direction of the housing 100, and the plurality of vertical members 310 are arranged at intervals along the horizontal direction, which can also be understood as the radial direction of the housing 100. The two horizontal members 320 arranged at the outermost ends in the axial direction of the housing 100 can both be connected to the water inlet pipe 200. The horizontal member 320 closest to the bottom surface of the housing 100 has the longest length in the horizontal direction, and the horizontal member 320 closest to the vertex of the housing 100 has the shortest length in the horizontal direction. Along the axial direction of the housing 100 from the vertex of the housing 100 to the bottom surface of the housing 100, the length of the horizontal member 320 in the horizontal direction gradually increases. In other words, for two adjacent horizontal members 320 arranged along the axial direction of the housing 100, the horizontal member 320 relatively closer to the bottom surface of the housing 100 has a greater length in the horizontal direction than the horizontal member 320 relatively farther from the bottom surface of the housing 100. The vertical members 310 are connected between two adjacent horizontal members 320, that is, one vertical member 310 is connected between any two adjacent horizontal members 320. Except for the vertical member 310 connected to the bottom surface closest to the housing 100, for other vertical members 310, one end of the vertical member 310 is connected to one end of one horizontal member 320 close to the water inlet pipe 200, and the other end of the vertical member 310 is connected to one end of the other horizontal member 320 far from the water inlet pipe 200. It can be understood that for the vertical member 310 connected to the bottom surface closest to the housing 100, the vertical member 310 is simultaneously connected to one ends of the two horizontal members 320 far from the water inlet pipe 200.

[0034] Therefore, by arranging the above-mentioned vertical members 310 and horizontal members 320, the vertical members 310 and the horizontal members 320 are connected to form a stepped structure. When water flows from the water inlet pipe 200 into the buffer chamber 110, through the guiding action of this stepped structure, it can ensure that the water in the buffer chamber 110 is evenly distributed, that is, ensure that the water in the buffer chamber 110 covers all the water distribution holes 120 in the circumferential direction of the housing 100, and ensure that the water flowing out from the water distribution holes 120 is evenly distributed in the inner cavity 12 of the tower body 11, thereby increasing the contact area between the water flowing out from the water distribution holes 120 and the air in the inner cavity 12, enabling sufficient heat exchange between the gas and the water flowing out from the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water, improving the heat dissipation efficiency of the high-temperature water, and thus ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3, in some embodiments, along the axial direction of the housing 100, that is, along the vertical direction, the housing 100 is axially slidably disposed in the inner cavity 12 of the cooling tower 10, so that the entire water distributor 16 can slide relative to the tower body 11 in the vertical direction. Specifically, when water is injected from the circulation pipe 14 into the buffer cavity 110 of the housing 100, the water will exert a force on the housing 100, that is, the water distributor 16 can slide up and down relative to the tower body 11 in the vertical direction by relying on the reaction force of the water. For example, when the water flow rate entering the housing 100 from the circulation pipe 14 increases, the housing 100 moves upward; when the water flow rate entering the housing 100 from the circulation pipe 14 decreases, the housing 100 moves downward. It can be understood that when the housing 100 moves upward, the density of the water near the central axis of the tower body 11 in the inner cavity 12 of the tower body 11 can be reasonably increased. Generally speaking, the water distribution density in the central area of the inner cavity 12 of the tower body 11 can be reasonably increased. When the housing 100 moves downward, the coverage area and range of the water flowing out from the water distribution holes 120 in the horizontal direction can be expanded. In this way, the contact area between the water flowing out from the water distribution holes 120 and the air in the inner cavity 12 can also be increased, so that sufficient heat exchange occurs between the gas and the water flowing out from the water distribution holes 120, ensuring that the gas in the inner cavity 12 fully absorbs the heat of the high-temperature water and improving the heat dissipation efficiency of the high-temperature water, thereby ensuring that the high-temperature water is quickly converted into low-temperature water that meets the requirements. Therefore, by making the housing 100 move up and down relative to the tower body 11, the water distributor 16 can be adapted to different water flow rates entering the buffer cavity 110, that is, to ensure that the water distributor 16 is adapted to changes in the water flow rate, thereby automatically adjusting the water distribution range.

[0036] In some embodiments, when the water flow rate in the housing 100 is less than 50% of the rated flow rate, the housing 100 moves to the lowest point. When the water flow rate in the housing 100 increases to 100% of the rated flow rate, the housing 100 moves to the highest point. That is, by setting a reasonable flow rate to drive the housing 100 to move in the vertical direction, it can be understood that a limiting structure can be provided in the tower body 11. The number of the limiting structures is two. The two limiting structures are respectively denoted as the upper limiting structure and the lower limiting structure. When the housing 100 abuts against the upper limiting structure, the housing 100 cannot continue to move upward. At this time, the housing 100 moves to the highest point. When the housing abuts against the lower limiting structure, the housing 100 cannot continue to move downward. At this time, the housing 100 moves to the lowest point.

[0037] The technical features of the above-described embodiments can be combined arbitrarily.
