Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a circulating water cooling and temperature reduction device. Background Technology

[0002] In industrial production and various cooling systems, circulating water cooling devices are key equipment for maintaining normal equipment operation. They use cooling towers to cool down the high-temperature circulating water that has absorbed heat from the equipment, and then the water is pressurized by a circulating water pump and sent back to the user end for reuse.

[0003] However, existing circulating water cooling towers have significant limitations in actual operation: they are significantly affected by seasonal temperature changes. In summer, the ambient temperature rises sharply, causing the ambient air temperature drawn into the cooling tower to increase, reducing the heat exchange temperature difference between the air and the high-temperature circulating water, and drastically reducing the cooling effect. This directly results in the circulating water supply temperature being too high, making it difficult to meet the equipment's cooling water temperature requirements. At the same time, the increased ambient temperature causes the overall temperature inside the cooling tower to rise, accelerating the evaporation process of the circulating water and leading to a significant increase in water loss, requiring frequent water replenishment to maintain normal system operation. In addition, to compensate for the insufficient cooling effect, it is necessary to increase the number of cooling fans in operation, which not only significantly increases energy consumption but also further exacerbates the evaporation loss of circulating water, creating a vicious cycle and increasing the system's operating costs and maintenance burden.

[0004] Therefore, a circulating water cooling device is proposed. Utility Model Content

[0027] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1:

[0031] Please see Figure 1 - Figure 6 This is the first embodiment of the present invention.

[0032] This embodiment provides a circulating water cooling device, including:

[0033] The housing 1 has ventilation slots 11 on both sides, and a liquid outlet pipe 12 is fixedly installed at the bottom of the back of the housing 1.

[0034] Spraying component 2 is disposed on the top of housing 1;

[0035] Top cover 3 is located on top of spray assembly 2, and exhaust assembly 4 is provided at both ends of top cover 3;

[0036] Two cooling water curtains 5 are fixedly installed on both sides of the housing 1 and located on the side of the ventilation slot 11.

[0037] Two filter components 6 are respectively disposed on both sides of the housing 1 and located at the bottom of the two cooling water curtains 5;

[0038] Cooling component 8 is located at the bottom of housing 1.

[0039] For example, the spraying assembly 2 includes a support frame 21, a diversion frame 22, a plurality of diversion pipes 23, a plurality of nozzles 24 and a water inlet pipe 25. The support frame 21 is fixedly installed on the top of the housing 1, the diversion frame 22 is fixedly installed on one side of the inner side of the support frame 21, the plurality of diversion pipes 23 are evenly fixedly installed on one side of the diversion frame 22, the plurality of nozzles 24 are evenly fixedly installed on the bottom of the plurality of diversion pipes 23, and the water inlet pipe 25 is fixedly installed on the other side of the diversion frame 22.

[0040] Furthermore, the connection between the diversion frame 22 and the support frame 21 is fixed by welding to ensure that it will not loosen or shift under the action of water pressure; the diversion pipe 23 is connected to the diversion frame 22 by a flange, which facilitates disassembly and replacement during later maintenance; the nozzle 24 adopts an atomizing nozzle design, which can convert the circulating water into fine droplets with a diameter of 0.5 to 1 mm, greatly increasing the contact area with air and improving heat exchange efficiency; a flow control valve is installed on the inlet pipe 25, which can adjust the inlet speed according to the temperature and flow requirements of the circulating water.

[0041] For example, each exhaust assembly 4 includes a fixing ring 41, a motor 42, a mounting bracket 43, and a fan blade 44. The fixing ring 41 is fixedly installed on the top of the top cover 3, the mounting bracket 43 is fixedly installed on the inner side of the fixing ring 41, the motor 42 is fixedly installed on the top of the mounting bracket 43, and the fan blade 44 is fixedly installed on the output end of the motor 42.

[0042] Furthermore, the fixing ring 41 is fixed to the top of the top cover 3 by bolts, and a sealing gasket is installed between the two to prevent rainwater from seeping into the device; the mounting bracket 43 adopts a triangular support structure to enhance the load-bearing capacity of the motor 42 and avoid violent shaking during motor operation; the motor 42 is a variable frequency motor, which can adjust the speed of the fan blade 44 according to the internal temperature of the device, reducing energy consumption while ensuring cooling effect; the fan blade 44 adopts a streamlined design and is made of high-strength engineering plastic, which has the characteristics of light weight, large air volume and low noise.

[0043] For example, the filter assembly 6 includes a collection frame 61 and a filter plate 62. The collection frame 61 is fixedly installed on the side of the housing 1, and the filter plate 62 is disposed on the inner side of the collection frame 61.

[0044] Furthermore, the inner wall of the collection frame 61 is inclined at an angle of 15°, which facilitates the rapid collection of water to the bottom and its flow into the return pipe; the filter plate 62 is made of stainless steel with evenly distributed filter holes of 0.2mm in diameter on its surface, which can effectively intercept impurities and particles in the water and prevent them from entering the cooling components and causing pipe blockage; the filter plate 62 is 5mm thick and has sufficient structural strength to withstand the impact of water flow without deformation.

[0045] For example, the filter assembly 6 also includes two suspension plates 63, which are fixedly installed at both ends of the top of the filter plate 62, and the two suspension plates 63 are also suspended above the collection frame 61.

[0046] Furthermore, the suspension plate 63 and the filter plate 62 are made by an integral molding process, which has high connection strength and is not easy to break; the two suspension plates 63 are symmetrically distributed, so that the filter plate 62 is subjected to uniform force in the collection frame 61, avoiding the filter plate tilting and the reduction of filtration effect due to the shift of the center of gravity.

[0047] In use, the high-temperature circulating water to be cooled enters the diversion frame 22 through the inlet pipe 25. After being diverted by multiple diversion pipes 23, it is sprayed downwards in the form of atomization by the nozzle 24. At the same time, the motor 42 of the exhaust assembly 4 drives the fan blades 44 to rotate, forming an upward airflow inside the top cover 3, which causes the air inside the device to flow upwards. The external air enters through the ventilation slots 11 on both sides of the housing 1. After being cooled by the cooling water curtain 5, it comes into full contact with the sprayed atomized circulating water and absorbs the heat from the circulating water. The hot air is discharged from the top of the top cover 3 under the action of the exhaust assembly. The cooled circulating water drips to the bottom of the housing 1. Some of the water that has not been completely evaporated flows into the collection frame 61 together with the water dripping from the cooling water curtain 5. After the water flows through the filter plate 62 to remove impurities, it enters the water tank 81 of the cooling assembly through the return pipe 85, completing one cooling cycle.

[0048] In summary, by setting up the cooling water curtain 5, the air entering the housing 1 can be pre-cooled, reducing the initial air temperature and thus increasing the heat exchange temperature difference between the air and the sprayed high-temperature atomized circulating water, significantly improving heat exchange efficiency. Even in summer when the ambient temperature is high, the cooling effect can be kept stable, avoiding excessively high circulating water supply temperature. At the same time, the evaporation and heat absorption process of the cooling water curtain 5 can also reduce the evaporation of the circulating water itself, reduce water loss, and reduce the frequency of water replenishment. Combined with the stable airflow formed by the exhaust fan 4, the cooling environment is further optimized, alleviating the problems of decreased cooling efficiency and increased energy consumption caused by increased ambient temperature in the prior art.

[0049] Example 2:

[0050] Please see Figure 2 - Figure 3 This is the second embodiment of the present utility model.

[0051] For example, the cooling assembly 8 includes a water tank 81, a cooler 82, a pump body 83, two output pipes 84 and two return pipes 85. The water tank 81 is fixedly installed at the bottom of the housing 1, the cooler 82 is fixedly installed at the bottom of the water tank 81, the pump body 83 is fixedly installed at the bottom of the water tank 81, the two output pipes 84 are fixedly installed at the output end of the pump body 83, and the two return pipes 85 are respectively fixedly installed on both sides of the water tank 81.

[0052] Furthermore, the water tank 81 is welded from stainless steel, and the inner wall is treated with anti-corrosion to effectively prevent rust caused by long-term water storage; the water tank 81 is equipped with a liquid level sensor, which can monitor the water level in real time. When the water level is lower than the preset value, the water replenishment device (not shown in the figure) is automatically triggered to ensure the stability of the system water volume; the cooler 82 uses a high-efficiency plate heat exchanger, which can quickly reduce the temperature of the circulating water in the water tank; the pump body 83 uses a stainless steel centrifugal pump, which has the characteristics of stable head, low noise and wear resistance, and its output power can be automatically adjusted according to the water demand of the cooling water curtain 5.

[0053] For example, the output end of the output pipe 84 is fixedly installed with the input end of the cooling water curtain 5, the input ends of the two return pipes 85 are fixedly installed at the bottom of the collection frame 61, and the bottom of the housing 1 is fixedly installed with a support frame 7.

[0054] Furthermore, both the output pipe 84 and the return pipe 85 are made of high-strength PVC pipe, which has good corrosion resistance and flexibility, and one-way valves are installed on the pipes to prevent water from flowing back and causing system turbulence. The connection between the output pipe 84 and the cooling water curtain 5 adopts a quick-connect joint design, which facilitates the disassembly, cleaning or replacement of the cooling water curtain 5 in the future. The diameter of the return pipe 85 is 20% larger than that of the output pipe 84 to ensure that the water in the collection frame 61 can quickly flow back to the water tank 81 and avoid water accumulation.

[0055] In use, the pump body 83 of the cooling assembly 8 delivers cold water from the water tank 81 to the cooling water curtain 5 through the output pipe 84, keeping the cooling water curtain 5 moist. When external air flows through the cooling water curtain 5, the water evaporates and absorbs heat from the air, thereby reducing the temperature of the air entering the housing 1. At the same time, the cooler 82 continuously cools the water in the water tank 81 to ensure that the water temperature delivered to the cooling water curtain 5 is at a low level. The water returning from the collection frame 61 enters the water tank 81 through the return pipe 85, mixes with the water in the water tank, and participates in the cooling cycle again.

[0056] In summary, through the coordinated operation of the cooling component 8 and the cooling water curtain 5, the air entering the device can be continuously cooled, increasing the heat exchange temperature difference between the air and the circulating water, and effectively improving the cooling effect; at the same time, the circulating water flows in the closed system, reducing evaporation loss and lowering the water replenishment frequency and energy consumption.
