Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a directional nozzle used in cooling towers. Background Art

[0002] Cooling tower sprinkler, also known as cooling tower nozzle, is an essential component in cooling tower. The main function of sprinkler is to evenly distribute water in the filling medium in the tower, so as to achieve efficient heat transfer and maintain the best working temperature.

[0003] Sprinkler design is important to ensure proper water distribution and coverage. Figure 1 , attached Figure 1 This is a working diagram of a cooling tower nozzle in the prior art. When the cooling tower nozzle is working, water is sprayed downward in a cone shape with a small top and a large bottom. However, if this type of cooling tower nozzle is installed at the edge of the water-spreading basin, since the edge of the water-spreading basin is close to the inner wall (shroud) of the cooling tower body, the cooling tower nozzle at the edge is likely to spray water outside the hood or filler, which will cause wall flow, leakage or water splashing outside the tower, affecting the cooling capacity of the cooling tower and wasting water resources. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a directional nozzle for a cooling tower, which can spray water in a directional manner and solve the problem of wall flow that is easy to cause in the past by improving the structure of the nozzle.

[0005] In order to solve the above technical problems, the utility model discloses a directional nozzle for a cooling tower, comprising a water inlet plate, a first splash plate and a second splash plate which are arranged in sequence from top to bottom, the bottom of the water inlet plate is fixedly connected to a vertically arranged baffle plate, a water inlet hole is opened in the middle of the water inlet plate, and the water inlet hole extends downward to form an arched portion which rests on the baffle plate to form a water inlet channel between the arched portion and the baffle plate, the first splash plate is semicircular and rests on the baffle plate to form a splash hole which is aligned with the water inlet channel in the height direction between the first splash plate and the baffle plate, and the second splash plate rests on the baffle plate and is located below the splash hole.

[0006] The water inlet hole is arranged in a semicircular or D-shape.

[0007] Wherein, the cross-sectional shape of the water inlet channel is semicircular or D-shaped.

[0008] The second splash plate is arranged in a semicircular shape.

[0009] Wherein, the top surface of the second deflector plate extends upwardly into a semi-conical portion.

[0010] Among them, a U-shaped bracket is fixedly installed on the bottom of the water inlet tray.

[0011] The second splash plate is fixedly installed at the middle position of the bottom of the U-shaped bracket.

[0012] Wherein, connecting rods are respectively extended inward from the middle of the left side and the middle of the right side of the U-shaped bracket, and the first splash plate is fixedly installed between the two connecting rods.

[0013] The four edges of the baffle are fixedly connected to the U-shaped bracket.

[0014] Wherein, a card slot is opened on the outer peripheral side of the water inlet tray.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0016] (1) By setting a vertical baffle to guide the water, the original cylindrical water inlet channel is changed to a semicircular water inlet channel, so that the original cone spraying range is changed to a semi-cone spraying range. Even if it is installed at the edge of the water basin, it can prevent water from spraying onto the inner wall of the cooling tower or the outside of the filler, thus solving the problem of wall flow and waste of water resources in the past.

[0017] (2) The overall structure of the nozzle is simple, which can effectively reduce wall flow and leakage and prevent the water sprayed from the nozzle from splashing outside the tower, thereby improving the cooling capacity of the cooling tower and ensuring the working stability of the cooling tower.

Specifically, a U-shaped bracket 6 is fixedly installed at the bottom of the inlet plate 2, the second deflector plate 4 is fixedly installed at the middle position of the bottom of the U-shaped bracket 6, and connecting rods 61 are extended inward from the middle of the left side and the middle of the right side of the U-shaped bracket 6, respectively, and the first deflector plate 3 is fixedly installed between the two connecting rods 61.

[0026] In this embodiment, a vertically arranged baffle plate 5 is also fixedly connected to the bottom of the water inlet tray 2, the top of the baffle plate 5 is fixedly connected to the bottom surface of the water inlet tray 2, and the four edges of the baffle plate 5 are fixedly connected to the U-shaped bracket 6. It should be noted that the water inlet tray 2, the first splash tray 3, the second splash tray, the U-shaped bracket 6 and the baffle plate 5 are an integral structure, which can be prepared by an integral molding method such as injection molding, 3D printing, and casting.

[0027] As an improvement, a water inlet hole 21 is provided in the middle of the water inlet tray 2, and the water inlet hole 21 extends downward to form an arched portion 22 resting on the baffle 5, so that a water inlet channel is formed between the arched portion 22 and the baffle 5. In order to guide the water in coordination with the baffle 5, preferably, the water inlet hole 21 and the water inlet channel are both semicircular or D-shaped. Compared with the conventional cylindrical water inlet channel, this structure can better achieve the effect of preventing wall flow, can ensure that the spraying range of the nozzle is in a semi-conical shape, and can effectively direct the spraying of water. In other embodiments, the water inlet hole 21 and the water inlet channel can also be set in other non-circular shapes.

[0028] In this embodiment, the first deflector plate 3 is semicircular and rests on the baffle plate 5, so that a splash hole 31 aligned with the water inlet channel in the height direction is formed between the first deflector plate 3 and the baffle plate 5. Similarly, the splash hole 31 is arranged in a semicircular shape. In other embodiments, the splash hole 31 can also be arranged in a D-shape or other non-circular shapes, as long as it can ensure that the spraying range is not a cone shape.

[0029] In this embodiment, the second splash plate 4 rests on the baffle plate 5 and is located below the splash hole 31. Optionally, the second splash plate 4 is arranged in a semicircular shape, and the top surface of the second splash plate 4 extends upward to form a semi-conical portion 41, which can ensure that the spraying range is in the shape of a semi-cone.

[0030] In this embodiment, a clamping groove 23 is provided on the outer peripheral side of the water inlet tray 2, and the clamping groove 23 facilitates the clamping or fixing of the nozzle with the external connecting member.

[0031] The directional cooling tower nozzle of this embodiment guides water by setting a vertical baffle 5, so that the original cylindrical water inlet channel is changed to a semicircular water inlet channel, so that the original cone spraying range is changed to a semi-cone spraying range. Even if it is installed at the edge of the water-spreading basin, it can prevent water from being sprayed on the inner wall of the cooling tower or the outside of the filler, solving the problem of easy wall flow and waste of water resources in the past. The overall structure of the nozzle is simple, which can effectively reduce wall flow and leakage, and prevent the water sprayed from the nozzle from splashing outside the tower, thereby improving the cooling capacity of the cooling tower and ensuring the working stability of the cooling tower.
