Technical Field

[0002] A cooling tower uses water as a circulating coolant to absorb heat from the system and discharge it into the atmosphere to reduce the water temperature.

[0003] After retrieval, a patent with the Chinese patent publication number CN212378544U discloses a combined pultruded fiberglass energy dissipation box, which includes an outer frame. A buffer plate is arranged in the middle of the interior of the outer frame. There is a water outlet between the side surface of the buffer plate and the outer frame. The top surface of the buffer plate is fixedly connected with a fixing component for fixing the buffer plate in the outer frame. The top of the outer frame is hermetically connected with an upper cover plate. A water inlet pipe penetrates through the center of the upper cover plate. The bottom end of the water inlet pipe is spaced from the surface of the buffer plate. The buffer plate is used to eliminate the energy of the incoming water, and the outer frame and the upper cover plate are used to eliminate splashing water. In the utility model, the buffer plate can block and buffer the water inlet pipe, thereby greatly weakening the energy of the incoming water and reducing surges and noise. The upper cover plate and the outer frame can block water from the top and side to prevent water from splashing out and overflowing.

[0004] The above solution can only buffer the incoming water and cannot reflect and resist the energy dissipation of the falling water, which limits the energy dissipation effect of the device and results in a low energy dissipation efficiency of the device.

[0005] Therefore, it is urgent to improve the reflective energy dissipation box for the cooling tower to solve the above problems. Summary of the Invention

[0006] Aiming at the problem in the prior art that only the incoming water can be buffered, the falling water cannot be reflected and resisted for energy dissipation, which limits the energy dissipation effect of the device and results in a low energy dissipation efficiency of the device, the utility model proposes the following technical solutions:

[0007] It includes a tower body and a water inlet pipe installed in the upper half of the tower body. A energy dissipation box is arranged below the water inlet pipe inside the tower body.

[0016] The reflected cooling water is slidably buffered by the arc-shaped flow-slowing cylinder, thereby reducing its flowing speed.

Detailed Embodiment

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0030] Embodiment 1

[0031] Figure 1 Shown is a schematic diagram of the overall sectional structure as a specific embodiment of the present utility model. Figure 1 Among them, it includes a tower body 1, and a water inlet pipe 2 installed on the upper half of the tower body 1. A dissipation box is arranged below the water inlet pipe 2 inside the tower body 1. The dissipation box includes a reflection dissipation part and a circulation dissipation part, including:

[0032] The reflection dissipation part includes an elastic net bag 4 with elastic stretching, a telescopic spring 9 for auxiliary ejection, and a limiting rod 8 for elastic limiting. Among them, the elastic net bag 4 is located directly below the water inlet pipe 2. A fixed support ring 3 is fixedly connected to the outside of the elastic net bag 4. A rebound connecting plate 5 is arranged below the elastic net bag 4. A plurality of first limiting cylinders 7 are fixedly connected to the lower end of the rebound connecting plate 5. The telescopic spring 9 and the limiting rod 8 are both fixedly arranged in the upper half of the first limiting cylinder 7. The first limiting cylinder 7 is inserted with a second limiting cylinder 10;

[0033] The circulation dissipation part includes an arc-shaped slow-flow cylinder 12 for circulation arc-shaped buffering, a diversion pipe 13 for diversion support, and a circulation cone 14 for uniform circulation support. Among them, the middle part of the lower end of the arc-shaped slow-flow cylinder 12 is fixedly arranged on the lower half of the outside of the fixed support ring 3. A plurality of diversion pipes 13 are arranged at the lower end of the arc-shaped slow-flow cylinder 12 and form a circle. The circulation cone 14 is provided with a plurality of circulation grooves 15, and the circulation grooves 15 penetrate through the upper and lower sides of the circulation cone 14.

[0034] When the device operates, the reflected cooling water flowing out from the water inlet pipe 2 is subjected to double dissipation of reflection and circulation through the reflection dissipation part and the circulation dissipation part inside the dissipation box, effectively reducing the damage caused to the internal parts of the tower body 1 when the reflected cooling water falls. Specifically, under the guidance of the water inlet pipe 2, the reflected cooling water outside can directly flow into the elastic net bag 4. Under the elastic expansion and contraction of the elastic net bag 4, and then under the pressure rebound of the telescopic spring 9, the reflected cooling water accumulated inside the elastic net bag 4 is reflected in the reverse direction of circulation. And under the semi-circular support of the elastic net bag 4, an effect of spreading around is formed. Part of it impacts with the falling reflected cooling water to slow down the flow speed. At the same time, the arc-shaped slow-flow cylinder 12 in the circulation dissipation part supports the spread reflected cooling water for arc-shaped circulation, so that its speed is slowed down during the flowing process. Then, under the flow guidance of a plurality of diversion pipes 13 and the circulation grooves 15, it uniformly flows downward, so as to achieve the effect of double deceleration of the high-speed falling reflected cooling water.

[0035] Figure 3 Shown is a schematic diagram of the ejection support structure as a specific embodiment of the present utility model. Figure 3 Among them, the reflection dissipation part further includes a fixed support cylinder 6 for ejection support and direction limiting. The first limiting cylinder 7 is inserted into the fixed support cylinder 6 and extends to both the inside and outside of it. The second limiting cylinder 10 is fixedly arranged inside the fixed support cylinder 6.

[0036] The lower half of the limiting rod 8 is inserted into and extends out of the lower end of the first limiting cylinder 7, and a first limiting plate with a specification larger than the insertion part of the limiting rod 8 and the first limiting cylinder 7 is arranged at the lower end of the limiting rod 8. A second limiting plate is arranged at the lower end of the first limiting cylinder 7 extending into the second limiting cylinder 10.

[0037] The limiting rod 8 and the first limiting plate form a limiting structure under the support of the first limiting cylinder 7, and the first limiting cylinder 7 and the second limiting plate form a limiting structure under the support of the second limiting cylinder 10. At the same time, under the guiding support of the fixed support cylinder 6, the distance and direction are stable and accurate when the telescopic spring 9 contracts and rebounds.

[0038] Embodiment 2

[0039] Figure 4 Shown is a schematic diagram of the overall structure of the flow energy dissipation part as a specific embodiment of the present invention. Figure 4 In it, the flow energy dissipation part further includes a fixing ring 16 for fixing the arc-shaped slow-flow cylinder 12 and a limiting support platform 11 for flow limiting. Among them, the fixing ring 16 is fixedly connected with the arc-shaped slow-flow cylinder 12, the outside of the fixing ring 16 is fixedly arranged inside the tower body 1, the limiting support platform 11 is fixedly arranged in the upper half part inside the flow cone 14, and the limiting support platform 11 is located among a plurality of flow grooves 15.

[0040] The specifications of a plurality of flow grooves 15 decrease from the middle part of the flow cone 14 to the outside, and the specifications of each circle of flow grooves 15 are the same, and the guide pipe 13 guides to between the outermost flow groove 15 and the inner wall of the flow cone 14.

[0041] When the cooling water is buffered and energy-dissipated inside the arc-shaped slow-flow cylinder 12, it is then guided by the guide pipe 13 to flow to the outermost part inside the flow cone 14. At the same time, the flow velocity is the largest when the cooling water contacts the flow cone 14. Therefore, by setting the outermost flow groove 15 to have the smallest specification, only part of the cooling water flows downward through the outer flow groove 15, so that the cooling water gradually flows toward the middle under the arc-shaped guidance of the flow cone 14, and the flow velocity of the cooling water can be buffered and reduced simultaneously under the gradual flow guidance of multiple layers of flow grooves 15, improving the uniformity of the cooling water flowing downward from the inside of the flow cone 14.

[0042] Figure 3 and Figure 4 Shown is a schematic diagram of the connection structure between the reflection energy dissipation part and the flow energy dissipation part as a specific embodiment of the present invention. Figure 3 and Figure 4 In it, the upper end of the limiting support platform 11 is fixedly connected with the fixed support cylinder 6, and the limiting support platform 11 is also used for supporting the fixed support cylinder 6.

[0043] By connecting and supporting the upper and lower devices on the limit support platform 11, the continuous energy dissipation by reflection and circulation of the cooling water is ensured.

[0044] Working principle: Under the guidance of the water inlet pipe 2, the cooling water outside can directly flow into the elastic mesh bag 4. Through the elastic expansion and contraction of the elastic mesh bag 4 and the compression and rebound of the telescopic spring 9, the accumulated cooling water inside the elastic mesh bag 4 is reflected in the reverse direction of circulation. And under the semicircular support of the elastic mesh bag 4, a diffusion effect in all directions is formed. Part of it impacts with the falling cooling water to slow down the flow speed. After the cooling water is buffered and energy-dissipated inside the arc-shaped flow-slowing cylinder 12, it is guided by the diversion pipe 13 to flow to the outermost side inside the circulation cone 14. At the same time, the flow speed is the largest when the cooling water contacts the circulation cone 14. Therefore, by setting the outermost circulation groove 15 to the smallest specification, only part of the cooling water flows downward through the outer circulation groove 15, so that the cooling water gradually flows toward the middle under the arc-shaped guidance of the circulation cone 14. And through the gradual flow guidance of the multi-layer circulation grooves 15, the flow speed of the cooling water can be buffered and reduced at the same time, improving the uniformity of the downward flow of the cooling water from inside the circulation cone 14.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
