Description

Technical Field

[0001] This utility model relates to the field of circulating water cooling technology, specifically to a high-efficiency circulating water cooling device for a factory. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to release heat into the atmosphere and lower the water temperature. It utilizes the heat exchange between water and air to generate steam, which then evaporates and carries away heat, achieving evaporative cooling. The device is generally cylindrical, hence the name cooling tower. Currently, there are various types of cooling towers. Among them, the square water cooling tower is an important heat exchange device in the industrial field. It uses air intake on both sides and a fan at the top to allow air to pass through the packing material inside the cooling tower, where it exchanges heat with hot water. The hot and humid air is then discharged outside the tower.

[0003] During operation, the cooling water in a square water cooling tower flows from top to bottom along the surface of the packing material under its own gravity. At the same time, the air intake on both sides can flow through the gaps in the packing material, thereby conducting heat and finally being drawn away by the fan.

[0004] However, in existing square water cooling towers, the contact area and contact time between the water flow and the packing material still need to be improved to further enhance the cooling effect of the square water cooling tower. Moreover, the existing packing plate will block the air delivered by the fan, resulting in a decrease in cooling efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned technology, this utility model provides a high-efficiency cooling device for circulating water in a factory area.

[0006] The technical solution of this utility model is as follows: A high-efficiency cooling equipment for circulating water in a factory area includes a frame, a fan, several packing plates, a spraying mechanism and a circulating pump. The frame is provided with an air inlet space, a spraying space, a packing space and a water collection space from top to bottom. The water collection space is provided with a circulating water recovery tank. The several packing plates are arranged in parallel and spaced apart in the packing space of the frame, and all of them are inclined. The packing plate includes a receiving end face facing the spraying space. Several intercepting protrusions are arranged at intervals along the vertical direction on the receiving end face. The spraying mechanism includes a frame and several nozzles. The frame is fixed to the spraying space of the machine frame. Several water supply pipes are provided on the frame at the gaps between each packing plate. Air inlet gaps are left between the several water supply pipes. The several nozzles are respectively installed on each water supply pipe and spray towards the receiving end face of the packing plate. The water that slides off the packing plate flows to the circulating water recovery tank. The circulating pump is connected to the circulating water recovery tank and each water supply pipe, and pumps the water in the circulating water recovery tank to each water supply pipe for circulating spraying. The fan is fixedly installed in the air inlet space of the frame, and transports air through the gaps between the air inlets and the gaps between the packing plates to exchange heat with the spray water.

[0007] A further feature of this invention is that the packing plate has several prisms between each of the intercepting protrusions, and several nozzles spray water onto the first row of prisms vertically above the packing plate, forming a splashing and dispersing water flow. The water overflowing from the several intercepting protrusions drips onto the prisms vertically below.

[0008] A further feature of this invention is that the circulating water recovery tank is provided with several hollow cooling pipes that pass through the cavity, allowing air to exchange heat with the water in the circulating water recovery tank through the hollow cooling pipes.

[0009] A further feature of this invention is that the frame is provided with a baffle on the outer periphery of the filling space. The baffle is provided with louvers for dissipating heat vapor. The blades of the louvers are inclined toward the inner side of the frame to guide the water splashed onto the blades toward the circulating water recovery tank.

[0010] The beneficial effects of this invention are as follows: Through the coordinated design of the fan, several packing plates, and the spraying mechanism, an air duct is formed that allows the fan's airflow to pass through the entire path, improving heat dissipation efficiency and preventing airflow from being blocked by the packing plates. Simultaneously, the inclined arrangement of the packing plates causes the sprayed water to form a thinner water film, further enhancing heat dissipation. Furthermore, the intercepting protrusions intercept the flowing water, causing it to aggregate and overflow, extending the time the water stays on the packing plates and its contact time with the cool air.

[0011] The designed prisms cause the sprayed water and overflowing water droplets to fall onto the prisms. The polyhedral structure of the prisms causes the water to splash irregularly, breaking up the water flow and forming splashed water droplets. The splashing process increases the contact area with the cold air, and at the same time, the secondary collisions form more water droplets, which then fall back onto the packing plate. Combined with multiple intercepting protrusions, a highly efficient cooling structure is formed.

[0012] The circulating water recovery tank collects water falling into the packing space and pumps it back to the spray mechanism for spray cooling again, improving the cooling effect. At the same time, the hollow heat-conducting pipes installed assist in cooling the water in the recovery tank.

[0013] The packing plate can be movably connected to the frame. One end of the packing plate can be moved horizontally by a motor to change different tilt angles according to process requirements and control the water flow rate. Attached Figure Description

It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings. Other related parts can be referred to the general design. In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.

[0019] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-5 As shown, A high-efficiency cooling device for circulating water in a factory includes a frame 1, a fan 2, several packing plates 3, a spraying mechanism, and a circulating pump 4. The frame 1 is provided with an air inlet space 11, a spraying space 12, a packing space 13, and a water collection space from top to bottom. The water collection space is provided with a circulating water recovery tank 14. The several packing plates 3 are arranged in parallel at intervals in the packing space 13 of the frame 1, and all of them are inclined. Each packing plate 3 includes a receiving end face facing the spraying space 12. Several intercepting protrusions 31 are arranged at intervals along the vertical direction on the receiving end face. The spraying mechanism includes a frame 41 and several nozzles 42. The frame 41 is fixed to the spraying space 12 of the frame 1. Several water supply pipes 43 are provided on the frame 41 at the gaps between each packing plate 3. There are air inlet gaps between the several water supply pipes 43. The several nozzles 42 are respectively provided on each water supply pipe 43 and spray towards the receiving end face of the packing plate 3. The water that slides off the packing plate 3 flows to the circulating water recovery tank 14. The circulating pump 4 is connected to the circulating water recovery tank 14 and each water supply pipe 43, and pumps the water in the circulating water recovery tank 14 to each water supply pipe 43 for circulating spraying. The fan 2 is fixedly installed in the air inlet space 11 of the frame 1, and transports air through the gaps between each air inlet and between each packing plate 3 to contact the spray water for heat exchange.

[0020] The packing plate 3 has several prisms 32 between each of the intercepting protrusions 31. The several nozzles 42 spray water onto the first row of prisms 32 vertically above the packing plate 3, forming a splashing and dispersing water flow. The water overflowing from the several intercepting protrusions 31 drips onto the prisms 32 vertically below.

[0021] The circulating water recovery tank 14 is provided with several hollow cooling pipes 141 that pass through the cavity, and air passes through the hollow cooling pipes 141 to exchange heat with the water in the circulating water recovery tank 14.

[0022] The frame 1 is provided with a baffle 5 on the outer periphery of the filling space 13. The baffle 5 is provided with louvers 51 for dissipating heat vapor. The blades of the louvers 51 are inclined toward the inside of the frame 1 to guide the water splashed onto the blades to flow toward the circulating water recovery tank 14.

[0023] Through the coordinated design of the fan 2, several packing plates 3, and the spraying mechanism, an air duct is formed that allows the airflow from the fan 2 to pass through the entire path, improving heat dissipation efficiency and preventing airflow from being blocked by the packing plates 3. At the same time, the inclined arrangement of the packing plates 3 causes the sprayed water to form a thinner water film, which is more conducive to heat dissipation. The intercepting protrusions 31 intercept the flowing water, causing it to aggregate and overflow, thus prolonging the time that the water stays on the packing plates 3 and the time it comes into contact with the cold air.

[0024] The designed prism 32 allows the sprayed water and overflowing water droplets to fall onto the prism 32. The polyhedral structure of the prism 32 causes the water to splash irregularly, breaking up the water flow and forming splashed water droplets. The splashing process increases the contact area with the cold air, and at the same time, the secondary collisions form more water droplets, which then fall back onto the packing plate 3. Combined with multiple intercepting protrusions 31, a highly efficient cooling structure is formed.

[0025] The circulating water recovery tank 14 collects the water falling from the packing space 13 and pumps it back to the spray mechanism for spray cooling again, improving the cooling effect. At the same time, the hollow heat conduction pipe is set to assist the water in the recovery tank in cooling and heat dissipation.

[0026] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
