A cooling tower nozzle

Abstract

This utility model belongs to the technical field of cooling tower spray heads, and discloses a cooling tower spray head, including a uniform sprayer and a uniform shower head support connected below the uniform sprayer. It also includes a spray head cover fitted onto the upper end of the uniform sprayer. A low-level flow-restricting pipe extends upward from the middle of the spray head cover to prevent foreign objects located at the bottom of the water distribution tray from entering its interior. This utility model provides an upward-extending low-level flow-restricting pipe at the upper end of the spray head cover, ensuring that water in the water distribution tray can only flow into the spray head cover after passing through the upper end of the low-level flow-restricting pipe. This effectively prevents foreign objects located at the bottom of the water distribution tray from entering its interior, thereby preventing spray head blockage and ensuring the spraying effect.

Description

Technical Field

[0001] This utility model belongs to the technical field of cooling tower nozzles, and specifically relates to a cooling tower nozzle. Background Technology

[0002] Common cooling tower structures are divided into counterflow towers and crossflow towers. In crossflow towers, nozzles are installed in the water distribution tray to spray water onto the packing material to achieve heat exchange.

[0003] Existing sprinklers, such as the authorized utility model with publication number CN109341407A, include a uniform sprinkler installed in a water distribution pan, with a uniform shower head support connected below the uniform sprinkler. This allows water in the water distribution pan to flow through the uniform sprinkler onto the uniform shower head support, forming a spray pattern that then sprays onto the packing material below, achieving uniform water distribution to the packing material. To achieve variable flow operation, a sprinkler cap is also fitted onto the upper end of the uniform sprinkler to meet better usage requirements.

[0004] However, in actual use, some rust, scale and other foreign objects at the bottom of the water distribution plate can enter between the nozzle cover and the water distribution nozzle, which can gradually clog the nozzle holes and affect the spraying effect of the nozzle. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower nozzle to solve the aforementioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cooling tower nozzle includes a uniform sprayer and a uniform shower head support connected below the uniform sprayer. It also includes a nozzle cover fitted onto the upper end of the uniform sprayer. A low-level flow-blocking pipe is formed extending upward from the middle of the nozzle cover to prevent foreign objects located at the bottom of the water distribution plate from entering its interior.

[0008] As a preferred technical solution of this utility model, the height of the low-position flow-blocking tube is 20-30mm.

[0009] As a preferred technical solution of this utility model, the low-position flow-blocking tube is a circular hole coaxially arranged with the central hole of the nozzle cover, and the inner diameter of the low-position flow-blocking tube is equal to the inner diameter of the central hole of the nozzle cover.

[0010] As a preferred technical solution of this utility model, the nozzle cover and the low-position flow-blocking tube are integrally formed.

[0011] Beneficial effects: This utility model has an upward-extending low-level flow-blocking pipe at the upper end of the nozzle cover, so that water in the water distribution tray can only flow into the nozzle cover after passing through the upper end of the low-level flow-blocking pipe. This can effectively prevent foreign objects located at the bottom of the water distribution tray from entering its interior, thereby preventing nozzle blockage and ensuring the spraying effect.

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0016] Example:

[0017] like Figure 1 and Figure 2 As shown, this embodiment provides a cooling tower nozzle, including a uniform water sprayer 1 and a uniform shower head support 2 connected below the uniform water sprayer 1. It also includes a nozzle cover 3 sleeved on the upper end of the uniform water sprayer 1. A low-level flow-blocking pipe 4 is formed in the middle of the nozzle cover 3, which is used to prevent foreign objects located at the bottom of the water distribution plate from entering its interior and to prevent nozzle blockage.

[0018] This invention features an upward-extending low-level flow-blocking pipe 4 at the upper end of the nozzle cover 3, ensuring that water in the water distribution tray can only flow into the nozzle cover 3 through the upper end of the low-level flow-blocking pipe 4. This effectively prevents foreign objects located at the bottom of the water distribution tray from entering its interior, thereby preventing nozzle blockage and ensuring the spraying effect.

[0019] As a preferred embodiment of this example, it should be further noted that the height of the low-level flow-blocking pipe 4 is 20-30mm. This ensures that the water in the water distribution tray can flow into the low-level flow-blocking pipe 4 while preventing foreign objects at the bottom of the water distribution tray from entering its interior.

[0020] As a preferred embodiment of this invention, it should be further explained that the low-position flow-blocking tube 4 is a circular hole coaxially arranged with the center hole of the nozzle cover 3, which makes the processing simpler, and the inner diameter of the low-position flow-blocking tube 4 is equal to the inner diameter of the center hole of the nozzle cover 3, so it will not affect the normal function of the nozzle cover 3.

[0021] As a preferred embodiment of this invention, it should be further noted that the nozzle cover 3 and the low-position flow-blocking tube 4 are integrally formed, which simplifies the processing and saves manufacturing costs.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
