Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a prefabricated cooling tower. Background Technology

[0002] A cooling tower is a device that cools water by exchanging heat with air. It utilizes the principle of heat absorption through water evaporation to spray circulating water carrying heat from industrial or air conditioning systems into droplets or films, allowing them to fully contact the air and causing some of the water to evaporate and carry away the heat, thereby lowering the water temperature. It consists of water spraying packing, ventilation equipment, and a water collector, and is used in the power, chemical, and metallurgical industries as part of industrial cooling systems.

[0003] Prefabricated cooling towers focus on modular prefabrication and on-site assembly. Factory-prefabricated components and on-site assembly significantly shorten the construction cycle. They are more precise and have better quality stability than traditional processes. The modular design is adaptable to different sites and can be expanded later through parallel modules. The prefabricated components are made of corrosion-resistant materials, have a long service life, and are detachable and maintainable, reducing construction waste. They have outstanding advantages in construction efficiency, adaptability, and environmental protection.

[0004] While prefabricated cooling towers focus on modular assembly to improve construction efficiency, they have shortcomings in the uniformity of water spraying. Traditional prefabricated water distribution systems often use fixed nozzles or simple pipeline designs. Due to the limitations of module splicing accuracy, water flow will experience pressure fluctuations at the interface, resulting in some areas being sprayed too densely, dead corners lacking water, and edge fillers forming heat exchange blind zones due to insufficient water volume, thus affecting the overall cooling efficiency.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The present invention provides an embodiment of a prefabricated cooling tower, comprising a tower body 1, a tower cover 2 fixedly connected to the top of the tower body 1, a dispersing mechanism 3 provided at the bottom of the tower cover 2 for dispersing water flow, a cooling mechanism 4 provided on the inner side of the tower body 1 for dissipating heat and cooling the material, a water spraying mechanism 5 provided on the top of the inner side of the tower body 1 for spraying water, and a support mechanism 6 provided on the right side of the bottom of the tower body 1 for supporting the material and collecting the falling water.

[0034] The dispersing mechanism 3 includes multiple mounting blocks 302. The tops of the multiple mounting blocks 302 are fixedly connected to the bottom perimeter of the tower cover 2. Two motors 301 are fixedly connected to the front top of the tower cover 2. Rotating shafts 303 are fixedly connected to the bottom of the multiple mounting blocks 302. Spiral agitators 304 are fixedly connected to the outer sides of the multiple rotating shafts 303. The output ends of the two motors 301 pass through the top of the tower cover 2 and the two front mounting blocks 302 and are fixedly connected to the two rotating shafts 303. The rotating shafts 303 are fixed to the tower cover 2 through the mounting blocks 302. The motors 301 drive the rotating shafts 303 to drive the spiral agitators 304 to rotate. By utilizing the mechanical cutting and centrifugal force of the spiral blades, the falling water flow is evenly decomposed, solving the problem of insufficient water spray uniformity caused by modular fixed nozzles.

[0035] Specifically, the dispersing mechanism 3 effectively solves the problem of uneven water spraying in the prefabricated cooling tower. Multiple mounting blocks 302 securely mount the rotating shaft 303 around the bottom of the tower cover 2, forming a regular dispersing array, ensuring structural stability and reliability. Two motors 301 on the front top of the tower cover 2 serve as power sources, with their outputs connected to the rotating shaft 303 via the mounting blocks 302, driving the rotating shaft 303 to rotate at high speed. This, in turn, drives the outer spiral agitator 304 to operate synchronously. In actual operation, the spiral blades of the spiral agitator 304 can efficiently disperse the falling water flow. Mechanical cutting breaks down the concentrated water flow into fine droplets. Simultaneously, the centrifugal force generated by rotation evenly disperses the droplets into the internal space of the tower body 1. Compared with traditional modular fixed nozzles, this effectively avoids cooling dead zones caused by uneven water flow distribution. The dispersion mechanism 3 is highly compatible with the prefabricated structure. The fixing method between the mounting block 302 and the tower cover 2 is simple and efficient, facilitating rapid on-site assembly. It not only retains the advantages of convenient installation of prefabricated cooling towers but also improves the uniformity of water spraying by dynamically dispersing the water flow, thereby improving the overall cooling efficiency and operational stability of the cooling tower.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The cooling mechanism 4 includes two large fans 401. The two large fans 401 are fixedly connected to the front and rear sides of the tower body 1 on adjacent sides. The front and rear sides of the tower body 1 are provided with mounting slots 402. The metal intercepting mesh 403 is fixedly connected to the opposite side of the two mounting slots 402. The two large fans 401 are fixedly connected to the opposite end of the two mounting slots 402. The left and right sides of the tower body 1 are provided with mounting slots 404. The interior of the two mounting slots 404 is fixedly connected with ventilation plates 405. By installing large fans 401 on the front and rear sides of the tower body 1, a directional ventilation channel is formed with the mounting slots 402 and the metal intercepting mesh 403, which forcibly accelerates the air flow. The ventilation plates 405 of the mounting slots 404 on the left and right sides assist in supplementing the airflow, so that the air around the tower body 1 forms a convection circulation, avoiding local airflow stagnation.

[0037] Specifically, the cooling mechanism 4 significantly improves cooling efficiency. The large fans 401 on the front and rear sides of the tower body 1 can quickly extract hot air from the tower. The mounting slot 402 provides a precise embedding space for the fans, ensuring that the large fans 401 fit tightly against the tower body 1 and reducing airflow leakage. The metal mesh 403 outside the slot plays a dual role: on the one hand, it prevents external debris from entering the tower body 1 and interfering with the cooling process; on the other hand, it optimizes the airflow direction, guiding the air to pass through the tower at high speed along the preset channel, enhancing the heat exchange efficiency with the water flow. The mounting slots 404 on the left and right sides of the tower body 1 and the ventilation plates 405 constitute an auxiliary ventilation system. When the large fans 401... When operating, the ventilation plate 405 can capture and guide the outside cold air to supplement the tower body 1, forming a surrounding air convection circulation, effectively avoiding the cooling blind zone caused by insufficient airflow in the corner of the tower body 1, and ensuring that the air is evenly distributed in all areas of the tower. In addition, the cooling mechanism 4 adopts a modular installation design, and the large fan 401, metal interception net 403 and ventilation plate 405 can be independently disassembled and installed. This facilitates equipment inspection and maintenance, and allows for flexible adjustment of fan power or increase of ventilation plate 405 according to actual cooling needs, achieving efficient air circulation and full utilization, and greatly improving the overall cooling performance and operational stability of the cooling tower.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The water spraying mechanism 5 includes a horizontal water pipe 501. The outer side of the horizontal water pipe 501 is connected to the upper middle part of the inner side of the tower body 1. Multiple spray heads 502 are fixedly connected to the bottom of the horizontal water pipe 501. Multiple nozzles 503 are fixedly connected to the bottom of the multiple spray heads 502 for spraying water. A water inlet assembly 504 is provided at the left end of the horizontal water pipe 501. The water inlet assembly 504 includes a water inlet bend 5041. The right end of the water inlet bend 5041 is connected to the left end of the horizontal water pipe 501. A water inlet valve 5042 is rotatably connected to the outer left side of the water inlet bend 5041. A water storage tank 10 is connected to the top of the water inlet bend 5041. A support rod 8 is fixedly connected to the bottom right side of the water storage tank 10. The bottom of the support rod 8 is fixedly connected to the top of the tower cover 2.

[0039] Specifically, the sprinkler mechanism 5 constructs a stable and efficient sprinkler system. The horizontal water pipe 501 runs horizontally through the upper middle part of the inner side of the tower body 1, forming a water supply network. Multiple spray heads 502 evenly distributed at the bottom, combined with nozzles 503, refine the water flow into water droplets of appropriate particle size, increasing the contact area with air and improving heat exchange efficiency. The water inlet assembly 504 ensures precise control and stable delivery of water flow. One end of the water inlet bend 5041 connects to the horizontal water pipe 501, and the other end connects to the water storage tank 10, forming a complete water delivery channel. The external water inlet valve 5042 can flexibly adjust the water flow. The water flow rate meets the cooling needs under different working conditions and avoids water waste. The water storage tank 10 is firmly mounted on the top of the tower cover 2 by the bottom support rod 8, ensuring the stability of high-level water supply and reducing the problem of uneven water spraying caused by water pressure fluctuations. The water spraying mechanism 5 adopts a modular assembly design, with each component tightly connected and easy to disassemble and maintain. Whether it is replacing the spray head 502 or the nozzle 503, or inspecting the water inlet valve 5042, it can be completed quickly. It not only achieves efficient water flow distribution and precise spraying, but also takes into account the advantages of convenient installation and simple maintenance of the prefabricated cooling tower.

[0040] Reference Figure 1 , Figure 2 and Figure 5 The support mechanism 6 includes a collection box 601. The bottom of the collection box 601 is fixedly connected to the bottom of the inner side of the tower body 1. The top of the collection box 601 is provided with a perforated support plate 603. Two metal support rods 602 are fixedly connected to the left and right sides of the perforated support plate 603. The ends of the multiple metal support rods 602 that are far apart are fixedly connected to the left and right sides inside the tower body 1 for supporting materials and collecting fallen water. A water outlet assembly 604 is provided on the right side of the collection box 601. The water outlet assembly 604 includes a water outlet bend 6041. The left end of the water outlet bend 6041 is connected to the right side of the collection box 601. A water outlet valve 6042 is rotatably connected to the top of the outer side of the water outlet bend 6041. A water collection tank 9 is connected to the bottom of the water outlet bend 6041. An evaporation port 7 is opened on the top of the tower cover 2.

[0041] Specifically, the collection box 601 of the support mechanism 6 is securely installed at the bottom inner side of the tower body 1, serving as a container for water collection. The perforated support plate 603 at the top not only effectively supports the cooling packing material but also allows the cooled water to smoothly seep into the collection box 601. The perforated support plate 603 is connected to the inner wall of the tower body 1 by two metal support rods 602 on each side, forming a robust support structure that ensures stability under the weight of the material and the impact of the water flow, preventing collapse and deformation. The water outlet component 604 enables the orderly discharge and recycling of collected water. One end of the water outlet bend 6041 is connected to the collection box 601, and the other end is connected to the water collection... Box 9 forms a complete drainage channel, and the water outlet valve 6042 on the outside flexibly controls the drainage flow, making it easy to adjust the water level or periodically discharge sewage according to actual needs. This ensures the smooth discharge of cooling water and avoids water waste. Together with the evaporation port 7 opened on the top of the tower cover 2, it accelerates the discharge of hot and humid air inside the tower and improves the overall cooling efficiency. The support mechanism 6 adopts a modular assembly design, with each component tightly connected and easy to disassemble. Whether it is cleaning the perforated bearing plate 603, inspecting the collection box 601, or maintaining the water outlet component 604, it can all be completed quickly, fully demonstrating the advantages of the prefabricated cooling tower in terms of convenient installation and simple maintenance.

[0042] Working Principle: When the prefabricated cooling tower is working, the water in the water storage tank 10 of the water spraying mechanism 5 flows through the inlet bend 5041 and the horizontal water pipe 501, and is initially sprayed into the interior of the tower body 1 through the spray head 502 and nozzle 503. At this time, the motor 301 of the dispersion mechanism 3 drives the rotating shaft 303, which drives the spiral agitator 304 to rotate at high speed, mechanically cutting and centrifugally dispersing the initially sprayed water flow and covering the interior of the tower body 1, ensuring that the water flow evenly contacts the cooling material. The cooling mechanism 4 starts simultaneously, and the large fans 401 on the front and rear sides operate, forming a directional airflow channel through the installation slot 1 402 and the metal interception net 403, quickly drawing out the hot air inside the tower. The installation slot 2 404 on the left and right sides and the ventilation plate 405 replenish fresh cold air, so that the air forms a circular convection circulation inside the tower body 1, accelerating the heat exchange process between the air and the water flow. The metal interception net 403 prevents debris from entering. To ensure the normal operation of the fan, after the water flows and exchanges heat with the air, the temperature decreases and seeps down into the collection box 601 through the perforated support plate 603, completing the material support and water collection functions of the support mechanism 6. The cooling water in the collection box 601 flows through the outlet bend 6041, and the operator can control the flow rate through the outlet valve 6042 to discharge the water to the water collection tank 9, realizing the recycling of water resources. At the same time, the evaporation port 7 at the top of the tower cover 2 helps to discharge the hot and humid air, further improving the cooling efficiency. All mechanisms adopt a modular design, and the mounting block 302 and metal support rod 602 can be quickly assembled, while the motor 301 and large fan 401 support independent disassembly and maintenance. This not only ensures the convenience of cooling tower installation, but also improves the overall cooling performance and operational stability through the functions of dispersing water flow, enhancing ventilation, stabilizing water delivery, and efficient water collection, meeting the diverse needs of industrial cooling scenarios.
