Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, specifically to a high-efficiency circulating water cooling tower device with multi-stage intelligent water distribution and self-cleaning. Background Technology

[0002] In industrial production, central air conditioning systems, and chemical process cooling, circulating water cooling towers are core equipment for water resource reuse and equipment cooling. Their cooling efficiency, operational stability, energy consumption, and maintenance costs directly affect the economics and environmental friendliness of the entire production system. With the expansion of industrial scale, tightening energy conservation and carbon reduction policies, and the intensification of water resource shortages, the market demand for efficient cooling towers is becoming increasingly urgent.

[0003] Current circulating water cooling towers used in industrial applications suffer from the following technical defects and industry pain points, severely restricting their overall performance improvement: Existing cooling towers generally adopt a single-stage water distribution design, using fixed nozzles or simple diversion pipes to achieve water flow distribution, which has significant shortcomings: First, the water distribution uniformity is poor, easily forming dead zones, resulting in insufficient air-water contact and maintaining cooling efficiency at a low level, making it difficult to meet the demands of high-load conditions; second, they lack intelligent control capabilities, and the water flow rate cannot be dynamically adjusted, leading to energy and water waste at low loads and insufficient cooling capacity at high loads; (Publication number CN1177602) Patent 33A discloses an industrial circulating water cooling tower, comprising: a lower shell, an upper shell, and a fixing assembly, wherein the upper shell is fixedly installed on the top of the lower shell by the fixing assembly; an outlet pipe and a return pipe, wherein the outlet pipe is installed at the bottom of the lower shell, and the return pipe is fixedly installed on the top of one side of the lower shell; and a heat dissipation assembly, wherein the heat dissipation assembly is installed inside the lower shell, and the water flow discharged from the return pipe drives the heat dissipation assembly to move, thereby cooling the water flow inside the lower shell. Although it attempts to use the potential energy of the return water to drive heat dissipation, it does not involve multi-stage water distribution and still cannot break through the efficiency bottleneck of single-stage water distribution.

[0004] In summary, current circulating water cooling towers suffer from numerous technical deficiencies in water distribution efficiency, making it difficult to meet the core requirements of industrial sectors for circulating water cooling tower devices. Therefore, developing a high-efficiency circulating water cooling tower device with multi-stage intelligent water distribution and self-cleaning capabilities has become a pressing technical challenge for the industry.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) A multi-segment intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device. When the load is high, all circulating water pipes are started to fill with water. The circulating water impact gap drives the central column to rotate rapidly. When the load is medium or low, the redundant circulating water pipes are closed, thereby reducing the speed of the central column. The central column is fixedly connected with the partition plate, thereby driving the filter and fan plate to rotate and draw air. The cooling intensity is adjusted in real time according to the working conditions, improving the flexibility of operation.

[0014] (2) The multi-segment intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device, when the flow rate in the water collection tank surges, the cylinder in the spokes will retract the contact pad, so that the guide mechanism is in rotation mode. The water flow from the connecting cylinder impacts the flow fan, drives the guide plate to rotate synchronously, and then drives the spiral scraper to scrape along the inner wall of the water collection tank. Through the twisting design of the spiral scraper, the impurities blocking the filter plate are guided to the impurity collection port, and the drain outlet is cleared in time, improving the smoothness of the circulating water flow.

[0015] (3) The multi-segment intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device, the unit components rotate in the opposite direction under the flushing of the cleaning water pipe, and then actively bring the high-pressure air and water into the circulating water pipe to flush the scale and suspended matter in the circulating water pipe. At the same time, the flushing water flows down and then senses the water volume through the flow sensor, so that the flow guiding mechanism starts to switch the cleaning state, thereby realizing the synchronous cleaning of the water distribution component and the water collection component. The whole area cleaning does not require manual disassembly, improves cleaning automation, reduces annual maintenance time, and improves the comprehensiveness of cleaning.

[0016] (4) The multi-segment intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device has a packing mechanism that starts and stops as needed according to the load. Redundant unit components are shut down when the load is low, thereby reducing energy consumption. The guide plate drives the fan to rotate through the circulating water flow into the connecting cylinder, forming a hydraulic self-driven rotation mode. The rotation is driven by the impact force of the water flow, eliminating the need for an additional motor and eliminating additional energy consumption. This improves the overall energy efficiency of the device.

[0017] (5) A multi-stage intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device. After passing through the unit components, the circulating water in the main structure enters the water collection component through the hollow part of the partition plate, so that the circulating water passes through a layer of filtration. After the circulating water enters the water collection mechanism through the connecting mechanism, the circulating water undergoes secondary sedimentation in the water collection tank through the opening of the bowl-shaped water collection tank. The clean water and circulating water are reused, and the sewage is discharged in compliance with standards after sedimentation treatment, thereby improving the water resource utilization rate.

[0018] (6) The multi-stage intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device allows the airflow to first enter between the outer cylinder and the clamping cylinder through the second and third air holes, and then enter between the inner cylinder and the clamping cylinder through the first air hole. Finally, the bottom of the packing mechanism flows to the top, allowing the air and water to exchange heat during this process, increasing the air-water contact rate, and thus improving the cooling efficiency.

[0019] (7) A multi-stage intelligent water distribution and self-cleaning high-efficiency circulating water cooling tower device with inclined fan blades that fit the filter screen. The air drawn in from the outside passes through the filter screen to filter the dust and clean it before entering the main body. The dust adhering to the outside of the filter screen is scraped off by contact with the fan blades during its rotation, which further increases the strength of the introduced airflow and improves the long-term stability of filtration and ventilation efficiency.

[0030] The working principle of this invention is as follows: The unit components are arranged longitudinally along the main cylinder assembly. The circulating water pipes 106 and cleaning water pipes 107 embedded on the main cylinder assembly correspond to the unit components. Based on the real-time collected data of circulating water input and output, the start / stop and flow parameters of the water distribution components can be dynamically adjusted. Under high load, all circulating water pipes 106 are started to fill with water, and the circulating water impacts the notch 204, causing the central column 201 to rotate rapidly. Under medium and low load, the redundant circulating water pipes 106 are shut off, thereby reducing the rotation speed of the central column 201. The central column 201 is fixedly connected to the partition plate 409, thereby driving the filter screen 411 and the fan plate 412 to rotate and draw air, adjusting the cooling intensity in real time according to the working conditions, and improving the flexibility of operation.

[0031] A bowl-shaped water collection trough 502 is provided inside the water collection cylinder 501 to guide sediment to the center by gravity, preventing sediment accumulation from affecting the water flow. The flow guiding mechanism 6 inside the water collection mechanism 5 accurately identifies the working conditions through the trigger element of the flow sensor 606. When the flow in the water collection trough 502 is stable, the cylinder inside the spoke 604 pushes the abutment pad 605 out to fit against the inner wall of the water collection trough 502, so that the flow guiding mechanism 6 is in a fixed mode, and the water flowing out from the connecting cylinder 401 is guided smoothly along the wall of the water collection trough 502 by the radial spokes 604. When the flow rate in the water collection tank 502 surges, the cylinder in the spoke 604 retracts the contact pad 605, causing the guide mechanism 6 to rotate. The water flowing out through the connecting cylinder 401 impacts the flow fan 603, causing the guide plate 601 to rotate synchronously. This, in turn, causes the spiral scraper 607 to scrape along the inner wall of the water collection tank 502. Through the torsional design of the spiral scraper 607, the impurities blocking the filter plate 506 are guided to the impurity collection port 503, thus clearing the drain port 505 in time and improving the smoothness of the circulating water flow.

[0032] The cleaning water pipe 107 and the circulating water pipe 106 are perpendicular to each other. When the cleaning water pipe 107 is activated, it performs high-pressure air-water mixed flushing. Due to the vertical arrangement of the cleaning water pipe 107 and the circulating water pipe 106, the cleaning water pipe 107 impacts the unit component in the reverse direction after activation, thereby washing off the impurities originally attached to the unit component. At the same time, the unit component rotates in the reverse direction under the flushing of the cleaning water pipe 107, thereby actively bringing the high-pressure air and water into the circulating water pipe 106 to flush away the scale and suspended matter in the circulating water pipe 106. Meanwhile, the flushing water flows downward and senses the water volume through the flow sensor 606, causing the flow guiding mechanism 6 to activate and switch the cleaning state, thereby achieving synchronous cleaning of the water distribution component and the water collection component. The entire area is cleaned without manual disassembly, improving cleaning automation, reducing annual maintenance time, and improving the comprehensiveness of cleaning.

[0033] The packing mechanism 2 starts and stops as needed according to the load, shutting down redundant unit components during low loads to reduce energy consumption. The guide plate 601 drives the fan 603 to rotate through the circulating water flowing into the connecting cylinder 401, forming a hydraulically self-driven rotation mode. The rotation is driven by the impact force of the water flow, eliminating the need for an additional motor and thus reducing additional energy consumption. This further improves the overall energy efficiency of the device.

[0034] The partition plate 409 has a hollow center. After passing through the unit components, the circulating water in the main structure 1 enters the water collection component through the hollow part of the partition plate 409, so that the circulating water undergoes a layer of filtration. After the circulating water enters the water collection mechanism 5 through the connecting mechanism 4, it undergoes secondary sedimentation in the bowl-shaped water collection tank 502. Clean water and circulating water are reused, and sewage is discharged in compliance with standards after sedimentation treatment, thereby improving the water resource utilization rate.

[0035] The unit component rotates under the impact of the water flow, which in turn drives the central column 201 to rotate. The partition plate 409 is fixedly connected to the central column 201, which in turn drives the filter screen 411 to rotate, which in turn drives the fan plate 412 to rotate, thereby drawing air through the filter screen 411. The airflow first enters between the outer cylinder 101 and the clamping cylinder 103 through the second air hole 406 and the third air hole 410, and then enters between the inner cylinder 102 and the clamping cylinder 103 through the first air hole 104. Finally, the airflow flows from the bottom to the top of the packing mechanism 2. During this process, the air and water exchange heat, improve the air-water contact rate, and thus improve the cooling efficiency.

[0036] The fan blades 408 are tilted and fit against the filter screen 411. The air drawn in from the outside passes through the filter screen 411 to filter the dust and clean it before entering the main body mechanism 1. The dust adhering to the outside of the filter screen 411 is scraped off by contact with the fan blades 408 during its rotation, which further increases the strength of the introduced airflow and improves the long-term stability of filtration and ventilation efficiency.
