Description

Technical Field

[0001] The utility model belongs to the field of cooling towers, relates to a cross-flow cooling tower, and specifically relates to a nozzle water inlet structure used for a cross-flow cooling tower. Background Art

[0002] Crossflow cooling tower is a common cooling tower. The nozzle of the crossflow cooling tower is installed in the water distribution tray, and the bottom of the nozzle is a shower structure. The cooling water is located above the water distribution tray. The cooling water exceeds the nozzle and flows down from the top inlet of the nozzle. After impacting the shower structure, the cooling water splashes to the filler below the nozzle. The large range of sprinkling can ensure the utilization rate of the filler, and then ensure the effect of the cooling tower. With the current nozzle structure, when the water level on the water distribution tray is low, the cooling water flows down from the top inlet of the nozzle, and the force of impacting the shower structure is relatively small, which makes the range of cooling water splashing small, and the shower cannot play the role of "sprinkling". A large amount of cooling water "drips" to the filler below. The filler utilization rate is obviously low, resulting in poor cooling effect of the crossflow cooling tower. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, a nozzle water inlet structure for a cross-flow cooling tower is provided. By improving the nozzle water inlet structure, a rotating water flow can be formed in the water inlet structure, which effectively expands the range of cooling water splashing, thereby improving the utilization rate of the filler, and the cooling effect of the cross-flow cooling tower is significantly improved.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a nozzle water inlet structure for a cross-flow cooling tower, including a cooling tower water tray, a nozzle arranged on the cooling tower water tray, and a shower arranged on the nozzle. The nozzle is provided with a water inlet pipe, and a plurality of inclined water inlets are opened on the side wall of the water inlet pipe. The water inlet is used to supply cooling water on the cooling tower water tray to enter the water inlet pipe to form a rotating water flow.

[0005] Furthermore, the water inlet is a corrugated edge structure.

[0006] Furthermore, the water inlet pipe and the nozzle are respectively provided with external threaded parts and internal threaded parts that match each other.

[0007] Furthermore, the water inlet pipe and the nozzle are respectively provided with mutually matching slots and buckles.

[0008] Furthermore, the water inlets are evenly distributed on the side wall of the water inlet pipe.

[0009] Furthermore, at least two limiting connecting columns are provided at the bottom of the nozzle, the bottom of the limiting connecting column is used to connect the shower head, and the top is used to limit the water inlet pipe. The limiting function can facilitate the longitudinal positioning of the water inlet above the cooling tower water tray, thereby determining the water level height range on the cooling tower water tray.

[0010] Beneficial effect: Compared with the prior art, the utility model improves the nozzle water inlet structure, and replaces the existing nozzle top water inlet method with the water inlet water inlet method through the design of a water inlet pipe and a plurality of inclined water inlets. Due to the innovative design of the water inlet, a rotating water flow can be formed in the water inlet pipe and the nozzle. On the basis of retaining the vertical impact force, the lateral impact force is increased, so that after the cooling water impacts the shower head, the splashing range is larger, which effectively expands the splashing range of the cooling water, thereby improving the filler utilization rate, and the cooling effect of the cross-flow cooling tower is significantly improved.

[0014] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0015] Embodiment 1:

[0016] like Figure 1 and Figure 3 As shown, the present embodiment provides a nozzle water inlet structure for a cross-flow cooling tower, comprising a cooling tower water distribution tray 5 of the cross-flow cooling tower, a nozzle 2 installed on the cooling tower water distribution tray 5, and a shower head 22 arranged at the bottom of the nozzle 2, a water inlet pipe 1 is installed on the nozzle 2 through a threaded connection, and the water inlet pipe 1 and the nozzle 2 are respectively provided with a matching external threaded portion 12 and an internal threaded portion 21, two limiting connecting columns 23 are arranged at the bottom of the nozzle 2, the bottom of the limiting connecting column 23 is used to connect the shower head 22, and the top is used to limit the water inlet pipe 1 longitudinally, and 6 inclined water inlets 11 are opened on the side wall of the water inlet pipe 1, and the 6 inclined water inlets 11 are evenly distributed on the side wall of the water inlet pipe 1, and the water inlet 11 is a corrugated edge structure with an inclination angle of 45 degrees.

[0017] Embodiment 2:

[0018] like Figure 2 and Figure 3 As shown, the present embodiment provides a nozzle water inlet structure for a cross-flow cooling tower, comprising a cooling tower water distribution tray 5 of the cross-flow cooling tower, a nozzle 2 installed on the cooling tower water distribution tray 5, and a shower head 22 arranged at the bottom of the nozzle 2. A water inlet pipe 1 is installed on the nozzle 2 through a card-type installation structure, and the water inlet pipe 1 and the nozzle 2 are respectively provided with mutually matching card grooves 13 and buckles (not shown in the figure), and two limiting connecting columns 23 are arranged at the bottom of the nozzle 2. The bottom of the limiting connecting column 23 is used to connect the shower head 22, and the top is used to longitudinally limit the water inlet pipe 1. Six inclined water inlets 11 are opened on the side wall of the water inlet pipe 1, and the six inclined water inlets 11 are evenly distributed on the side wall of the water inlet pipe 1. The water inlet 11 is a corrugated edge structure with an inclination angle of 45 degrees.

[0019] Embodiment 3:

[0020] In this embodiment, the nozzle water inlet structure provided in Embodiment 1 is used as an example. Figure 3 As shown, the cooling water 41 is located above the cooling tower water distribution tray 5 of the cross-flow cooling tower. The cooling water 41 enters the water inlet pipe 1 through the water inlet 11. Due to the special structure of the water inlet 11, the entering cooling water 41 will form a rotating water flow 42 in the water inlet pipe 1. The rotating water flow 42 moves downward and separates from the nozzle 2 until it impacts the shower head 22, forming a splashing water flow 43, and flows toward the filler 6.

[0021] It can be seen that due to the innovative design of the water inlet 11, a rotating water flow 42 can be formed in the water inlet pipe 1 and the nozzle 2. On the basis of retaining the vertical impact force, the lateral impact force is increased, so that after the cooling water impacts the shower head 22, the splashing range is larger, which effectively expands the splashing range of the cooling water, thereby improving the utilization rate of the filler 6, and the cooling effect of the cross-flow cooling tower is significantly improved.
