Description

Technical Field

[0001] This application relates to the field of counterflow towers, and more particularly to a sprinkler for use in counterflow cooling towers. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and release it into the atmosphere in order to lower the water temperature. A counter-flow cooling tower is a heat exchange device that uses the counter-flow contact of water and air to achieve efficient heat dissipation. During the operation of a counter-flow cooling tower, the circulating water is evenly sprayed onto the packing material through the sprinklers on the main and auxiliary pipes, so that the packing material cools the circulating water and lowers the water temperature.

[0003] When the atmospheric temperature drops significantly, the amount of cooling water used will decrease, and even less water will enter from outside the tower. The circulating water cannot be sprayed evenly onto the packing material, so the packing material that is not in contact with water cannot exert a cooling effect. Utility Model Content

[0004] In order to enable the sprinkler to evenly distribute the circulating water to the packing, this application provides a sprinkler for counter-flow cooling towers.

[0005] This application provides a water sprayer for counter-flow cooling towers, employing the following technical solution: A sprinkler for a counter-flow cooling tower includes a nozzle base and a sprinkler bracket. The nozzle base is mounted on the main pipe of the counter-flow tower and has an arc-shaped surface that conforms to the surface of the main pipe. The sprinkler bracket includes a mounting cylinder and a mounting support. The mounting support is a two-legged bracket with a rotating hole at its bottom for rotatable connection with blades having a fixed axis. The two legs of the mounting support and the rotating hole are located in the same plane. The two legs of the mounting support are mounted on the mounting cylinder, which has several locking blocks distributed circumferentially along its axis. The nozzle base has several locking grooves for accommodating the locking blocks. The mounting bracket has two different installation states, with the plane of the mounting bracket parallel to or perpendicular to the axis of the arc-shaped surface.

[0006] By adopting the above technical solution, the nozzle holder fits the surface of the counter-flow tower's main and auxiliary pipes through its arc-shaped surface, achieving a stable connection with the main and auxiliary pipes and ensuring the firmness of the installation foundation. The design of the two-legged bracket, combined with the rotating hole and the fixed-axis blade rotational connection, and the fact that the two legs of the mounting bracket and the rotating hole are on the same plane, provides a stable rotational support structure for the blades, ensuring that the blades can rotate reliably. The snap-fit ​​block on the mounting cylinder cooperates with the snap-fit ​​groove on the nozzle holder to achieve a detachable connection between the sprinkler bracket and the nozzle holder, facilitating installation and maintenance. The two distribution methods of the snap-fit ​​block allow the plane on which the mounting bracket is located to be parallel or perpendicular to the arc-shaped surface, thereby adjusting the direction of the blades. By alternating the distribution of the two mounting brackets in different states, the complementary water spray area is achieved, realizing uniform water spraying of the packing under different working conditions and giving full play to the cooling effect of the packing.

[0007] Optionally, the snap-fit ​​groove includes an inlet groove, an annular groove, and a receiving groove. The inlet groove extends along the axial direction of the nozzle seat, and one end of the inlet groove penetrates the bottom of the nozzle seat. The annular groove extends along the outer arc surface of the nozzle seat, and one end of the annular groove communicates with the side wall of the inlet groove. The receiving groove extends along the axial direction of the nozzle seat, and one end of the receiving groove communicates with the other end of the annular groove. The bottom height of the receiving groove is lower than that of the annular groove.

[0008] By adopting the above technical solution, the snap-fit ​​groove consists of an inlet groove, an annular groove, and a receiving groove. The inlet groove facilitates the snap-fit ​​block to enter along the axis of the nozzle seat, the annular groove allows the snap-fit ​​block to move along the outer arc surface of the nozzle seat, and the receiving groove can limit and fix the snap-fit ​​block. The bottom of the receiving groove is lower than that of the annular groove. The snap-fit ​​block is stably engaged by the weight of the mounting bracket itself, preventing the mounting cylinder from detaching from the nozzle seat due to vibration or other reasons during use, and ensuring the reliability of the connection between the sprinkler bracket and the nozzle seat.

[0009] Optionally, one end of the inlet groove is provided with a guide slope to facilitate the entry of the snap-fit ​​block.

[0010] By adopting the above technical solution, the guide slope at one end of the slot can guide the snap-fit ​​block into the slot, reducing the difficulty of aligning the snap-fit ​​block with the slot, making the installation process more convenient and efficient, and improving installation efficiency.

[0011] Optionally, the nozzle seat is provided with a flow guide cone, the diameter of which gradually decreases along the direction from the nozzle seat to the sprinkler bracket.

[0012] By adopting the above technical solution, the diameter of the guide cone gradually decreases along the direction from the nozzle seat to the sprinkler bracket. Combined with the flow characteristics of water, it can converge and guide the water flow, making the water flow more concentrated on the blades, increasing the impact force of the water flow on the blades, ensuring that the blades can rotate stably, and thus ensuring the stability of the sprinkling effect.

[0013] Optionally, the guide cone is connected to the nozzle seat by a thread, thereby changing the distance between the guide cone and the blade.

[0014] By adopting the above technical solution, the guide cone and the nozzle seat are connected by threads, and the distance between the guide cone and the blade can be changed by rotating the guide cone; adapting to different water pressure and water volume conditions, optimizing the effect of water flow on the blade, thereby adjusting the spraying range and uniformity.

[0015] Optionally, the cross-section of the mounting bracket is elliptical.

[0016] By adopting the above technical solution, the support frame has an elliptical cross-section. This cross-section design can reduce the resistance caused by water flow impact while ensuring the structural strength of the support frame. It also helps to disperse stress, improve the fracture resistance of the support frame, and extend its service life.

[0017] Optionally, the rotating hole is coaxially arranged with the mounting cylinder.

[0018] By adopting the above technical solution, the rotating hole and the mounting cylinder are set coaxially, so that the rotation axis of the blade is consistent with the axis of the mounting cylinder, ensuring the stability and symmetry of the blade rotation, and avoiding the imbalance of blade rotation caused by axis offset, which in turn affects the uniformity and stability of water spraying.

[0019] Optionally, the mounting bracket includes two vertical sections, two concave rounded corner sections, two convex rounded corner sections, and a connecting section. One end of each of the two vertical sections is disposed on the mounting cylinder, one end of each concave rounded corner section is disposed on the other end of the vertical section, one end of each convex rounded corner section is disposed on the other end of each concave rounded corner section, and the other ends of each of the two convex rounded corner sections are disposed on the connecting section. The connection point is located at 2 / 3 of the height of the connecting section, and the rotating hole is located at the bottom end of the connecting section.

[0020] By adopting the above technical solution, the special structure of the mounting bracket ensures a reasonable stress distribution. The vertical section provides a stable support foundation, the concave and convex rounded corner sections disperse stress, and the connecting section connects all parts into a whole. Furthermore, the rotation hole is located at the bottom of the connecting section, ensuring structural stability during blade rotation and reducing the risk of bracket breakage.

[0021] Optionally, the top of the connecting segment is a rounded blunt end.

[0022] By adopting the above technical solution, the shape of the combined section guides the water flow downward along the outer surface of the bushing cylinder, thereby reducing water flow turbulence and energy loss. Simultaneously, it guides the water flow direction, reduces the impact force on the support structure, protects the support structure, and allows the water flow to participate more rationally in the water spraying process. Optionally, the connection between the mounting bracket and the mounting cylinder is thickened.

[0023] By adopting the above technical solution, the thickened part can enhance the structural strength of the connection, effectively resist the influence of axial force, reduce stress concentration, and improve the overall service life and reliability of the support.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The head seat fits the counter-flow tower's main pipe with an arc-shaped surface to ensure installation stability; by alternately distributing two sets of sprinkler supports in different states, the water spraying areas of adjacent nozzles can complement each other, thereby adapting to different flow conditions. 2. The receiving groove consists of an inlet groove, an annular groove, and a receiving groove. The guide slope of the inlet groove facilitates the entry of the locking block, the annular groove allows the locking block to move, and the receiving groove securely engages the locking block through the height difference, effectively preventing the installation cylinder from detaching and ensuring the firm connection between the sprinkler bracket and the nozzle seat. 3. The threaded connection between the guide cone and the nozzle seat can change the distance between it and the blades. Combined with its own diameter variation design, it can optimize the water flow effect for different water pressures, ensure that the water is evenly sprayed on the packing, give full play to the cooling effect of the packing at all points, and reduce the water temperature as much as possible.

The rotating hole 225 is coaxially arranged with the mounting cylinder 21 and is rotatably connected to the blade with a fixed axis.

[0037] The implementation principle of a sprinkler for a counterflow cooling tower in this application embodiment is as follows: by fitting the nozzle seat 1 arc surface 11 with the counterflow tower main pipe, and combining the two distribution methods of the sprinkler bracket 2 snap-fit ​​block 23, the plane direction of the mounting bracket 22 can be flexibly adjusted. With the complementary design of the azimuth angle of adjacent nozzles, the problem of uneven spraying caused by seasonal changes in cooling water consumption and differences in water pressure of different nozzles is solved, ensuring that water evenly covers all parts of the packing, giving full play to the cooling effect of the packing, and minimizing the water temperature.
