Description

Technical Field

[0001] This invention relates to the field of humidification and air cooling technology, and in particular to an industrial high-efficiency insulated humidification and air cooling device. Background Technology

[0002] Traditional large-scale humidifying air coolers have the following technical problems: 1. The internal structure and packing structure of the precooling components are unreasonable, which causes the flow velocity of the outside air to decrease significantly after passing through the water curtain, affecting the heat exchange efficiency after entering the heat exchanger; 2. When the precooling components are not used in winter, the outside air still needs to flow through the packing to enter the heat exchanger, which leads to a decrease in flow velocity and affects the heat exchange efficiency.

[0003] Therefore, how to create a new type of industrial high-efficiency insulated humidifying air cooler is one of the important research and development topics at present. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an industrial high-efficiency insulated humidifying air cooler, which enables the outside air to flow out more quickly after being humidified and cooled by the water curtain, thereby improving the heat exchange efficiency after entering the heat exchanger. Furthermore, when the water curtain is not used in winter, the air can enter the heat exchanger through the air valve, thus overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides an industrial high-efficiency insulated humidifying air cooler, including a support frame, side baffles, a cooling mechanism and a fan;

[0006] The support frame is a rectangular box-shaped frame with side baffles installed on the left and right sides, and multiple cooling mechanisms installed on the front and rear sides through mounting brackets, so that the cooling mechanisms are arranged in several rows.

[0007] The two sides of the support frame, where the cooling mechanism is installed, are the air intake areas, and the top is the exhaust area;

[0008] The cooling structure includes a heat exchange component and a pre-cooling component. The pre-cooling component is installed on the outside of the heat exchange component. External air enters the pre-cooling component through the air inlet area to be humidified and cooled, then enters the heat exchange component to exchange heat with the medium to be cooled, and finally exits through the exhaust area.

[0009] The precooling component includes a water distribution main pipe and a packing material. The water distribution main pipe is horizontally arranged near the top of the precooling component and has multiple spray holes. The packing material is arranged below the water distribution main pipe.

[0010] The packing material contains multiple closely arranged wavy packing units. Each packing unit is divided into a humidification section in the front half and an acceleration section in the back half. The humidification section has an equal thickness, while the acceleration section has an increasing thickness. Water flows from top to bottom through the gaps between the humidification sections of adjacent packing units to form a water curtain. External air passes through the water curtain from the outside to the inside to complete humidification and cooling, and then flows out through the acceleration section at an accelerated speed.

[0011] As an improvement of the present invention, the precooling component further includes a baffle plate, a first water distribution plate, and a second water distribution plate;

[0012] The baffle plate is installed above the main water distribution pipe. The spray holes on the main water distribution pipe are opened upward and outward. The baffle plate is used to block the sprayed water flow.

[0013] The first water distribution plate is inclined at the outside and lower at the inside, and water distribution holes are opened near the outer side of the first water distribution plate.

[0014] The second water distribution plate is inclined and positioned below the first water distribution plate, with the outer side lower than the inner side;

[0015] The water baffle, the first water distribution plate, and the second water distribution plate work together to form a water curtain within the humidification section of the packing unit.

[0016] Furthermore, the precooling component also includes air valves, which have multiple rotating and opening / closing air valve blades inside. The air valves are installed at intervals between the packing along the length of the precooling component, and the positions of the air valves are staggered among the multiple rows of precooling components. There are no spray holes on the top water distribution main pipe at the location where the air valves are installed.

[0017] Furthermore, the cooling mechanism also includes an airflow control component and a cleaning component, and the mounting bracket is provided with a side guard plate to provide installation support for the cooling mechanism;

[0018] The heat exchange component, cleaning component, precooling component, and air volume control component are installed sequentially from the inside to the outside on the side guard plate.

[0019] Furthermore, the airflow control component includes a shielding blade, a blade drive motor, a blade gear, and a rack;

[0020] One end of the shielding blade is rotatably connected to the side guard plate, one end of the blade drive motor is fixedly connected to the side guard plate, one end of the blade gear is fixedly connected to the shielding blade, one end of the blade gear is fixedly connected to the power output end of the blade drive motor, one end of the rack is slidably connected to the side guard plate, and one end of the blade gear meshes with the rack.

[0021] Furthermore, the cleaning assembly includes a limiting guide rail, a cleaning brush, a cleaning motor, sprockets, and a chain. One end of the limiting guide rail and the cleaning motor is fixedly connected to the side guard plate. One end of the multiple sprockets is rotatably connected to the side guard plate, and the other end of the sprocket is fixedly connected to the power output end of the cleaning motor. One end of the chain is driven and connected to the sprockets. One end of the cleaning brush is rotatably connected to the chain. One end of the limiting rod is slidably connected to the limiting guide rail, and one end of the cleaning brush is slidably connected to the limiting rod.

[0022] Furthermore, a sealing strip is slidably connected to one side of the side guard plate, and one end of the sealing strip is fixedly connected to the chain.

[0023] Furthermore, a sand-proof component is provided on the outside of the precooling component.

[0024] Furthermore, ladders are provided outside the side panels on the left and right sides of the support frame, and multiple maintenance walkways are provided outside the front and rear sides of the support frame.

[0025] Furthermore, bottom diagonal braces and side supports are fixedly connected below the support frame and side baffle.

[0026] With this design, the present invention has at least the following advantages.

[0027] 1. The precooling component of the present invention uses a packing material that includes multiple closely arranged packing units. The thickness of a single packing unit is equal in the humidification section in the first half and increases in the thickness in the acceleration section in the second half, thereby gradually narrowing the gap between adjacent packing units and forming an air acceleration channel. Without changing the air flow rate, the air outlet velocity of the precooling component is increased so that turbulence is formed after entering the heat exchange component, thereby improving the heat exchange efficiency.

[0028] 2. The precooling component of the present invention controls the position of the water curtain through the baffle plate, the first water distribution plate and the second water distribution plate, so that it is only formed in the humidification part of the front half of the packing unit. On the one hand, it does not affect the air flow rate of the acceleration part, and on the other hand, the shape of the gradually narrowing gap of the acceleration part can also reduce water drift towards the heat exchange component and avoid scale buildup on the heat exchange component.

[0029] 3. The precooling components of this invention are equipped with air valves at intervals along the length direction. When not in use during winter, outside air can directly enter the heat exchange components through the air valves. The air valves on the multiple rows of precooling components are staggered to facilitate more uniform airflow.

[0030] 4. The heat exchange component of this invention is a tube-fin heat exchanger with a compact internal structure. The fin spacing and number of tube rows are designed for optimal air resistance, making it more suitable for use in large-scale chemical equipment. It can save 80-90% of water and is suitable for application in arid and water-scarce areas in Northwest China.

[0031] 5. The present invention provides ladders on the outside of the baffles on the left and right sides of the support frame, and provides corresponding maintenance walkways on the front and rear sides according to the number of rows of cooling mechanisms installed, so as to facilitate maintenance and repair by staff.

[0032] 6. This invention uses a blade-driven motor to change the angle of all the blocking blades, which can adjust the air intake volume or close the air intake area to prevent a large amount of sand from entering.

[0033] 7. The present invention drives the chain to rotate by a sweeping motor, which in turn drives the sweeping brush with bristles on both sides to move in a rectangular trajectory. In this way, after the sweeping brush moves one revolution, the heat exchange components and pre-cooling components on both sides can be cleaned, and the device can be automatically maintained.

[0034] 8. By incorporating sand-proof components, this invention can reduce the amount of sand directly impacting the cooling mechanism and extend its service life. Attached Figure Description

[0051] Please see Figures 1 to 14 The present invention provides an industrial high-efficiency insulated humidifying air cooler, including a support frame 1, a side baffle 2, a cooling mechanism 6 and a fan 15.

[0052] The support frame 1 is a rectangular box-shaped frame with side baffles 2 installed on the left and right sides, and multiple cooling mechanisms 6 installed on the front and rear sides.

[0053] The support frame 1 is equipped with a cooling mechanism 6. The two sides (i.e. the front and rear sides) are the air intake area 18, and the top is the exhaust area 13.

[0054] The cooling structure 6 has a large overall volume and needs to be divided into multiple blocks. Each block is installed onto the support frame 1 one by one through the mounting frame 3, and finally arranged into four rows.

[0055] The mounting frame 3 is a rectangular frame with side guards 10 on both sides to provide mounting support for the cooling mechanism 6.

[0056] The cooling structure 6 includes, from the inside out, a heat exchange component 4, a cleaning component, a pre-cooling component 5, a sand-proof component 19, and an airflow control component. All of the above components are installed on the side guard plate 10.

[0057] Please see Figure 8 and Figure 9 The precooling component 5 includes a water distribution main pipe 32, a water baffle 33, a first water distribution plate 34, a second water distribution plate 35, a packing 37, and an air valve 41.

[0058] The main water distribution pipe 32 is horizontally positioned near the top of the precooling component 5 and has multiple spray holes 31. The spray holes 31 are oriented upwards and tilted outwards. The main water distribution pipe 32 is connected to an external water supply pipe 7 and is used to spray water into the precooling component 5 to form a water curtain.

[0059] The baffle plate 33 is positioned above the main water distribution pipe 32 and acts as a top plate to seal the top of the precooling component 5, thereby blocking the sprayed water flow. The baffle plate 33 is bent into a trapezoidal groove shape, which, in conjunction with the opening direction of the spray holes 31, ensures that most of the water flow is blocked and located near the outer side, while a small portion is located on the inner side.

[0060] The first water distribution plate 34 is inclined downwards from the outside to the inside and is located below the main water distribution pipe 32. The first water distribution plate 34 has water distribution holes 36 near the outer side. The function of the first water distribution plate 34 is to distribute most of the blocked water flow downwards evenly through the water distribution holes 36, forming a water curtain near the outer half of the pipe.

[0061] The second water distribution plate 34 is inclined and positioned below the first water distribution plate 34 with a lower outer edge and a higher inner edge. The width of the second water distribution plate 34 is half the total width of the precooling component 5. Its function is to guide a small portion of the water flow that is blocked to the inside to the outside, so as to prevent water from falling down in the middle of the flow near the inside.

[0062] Please see Figure 10 In the diagram, solid arrows indicate the direction of water flow, and hollow arrows indicate the direction of air flow.

[0063] The packing 37 contains multiple closely arranged wavy packing units 38, and each packing unit 38 is divided into a humidification section 39 in the first half and an acceleration section 40 in the second half.

[0064] The thickness of each individual packing unit 38 is equal in the humidification section 39, while the thickness increases in the acceleration section 40. Water flows from top to bottom through the gaps between adjacent packing units 38 in the humidification section 39 to form a water curtain. Due to the cooperation of the baffle plate 33, the first water distribution plate 34, and the second water distribution plate 35, the water curtain is formed only in the humidification section 39, while there is no water curtain in the acceleration section 40.

[0065] External air flows in from the outside to the inside through the gaps between adjacent packing units 38, and comes into full contact with the water curtain in the humidification section 39 to complete humidification and cooling. At the acceleration section 40, due to the increasing thickness of individual packing units 38, the gaps gradually decrease, forming a narrowing airflow channel, which allows the air to flow out faster. The faster airflow velocity helps to form turbulence between the heat dissipation fins 30 in the heat exchange component 4, thereby improving the heat exchange efficiency.

[0066] Please see Figures 5 to 7In this embodiment, the precooling component 5 is also provided with an air valve 41. The air valve 41 is installed at intervals between the packing 37 along the length direction of the precooling component 5. The top water distribution main pipe 32 at the location where the air valve 41 is installed has no spray hole 31.

[0067] The air valve 41 is internally equipped with multiple rotating air valve blades 42. In summer, the air valve 41 is in the closed state, and air flows through the packing 37 and through the pre-cooling component 5. In winter, the air valve 41 is in the open state, and air flows through the air valve 41 and through the pre-cooling component 5 into the heat exchange component 4.

[0068] To ensure a more even flow of air, the positions of the air valves 41 between the multiple rows of precooling components 5 are staggered.

[0069] Please see Figures 11 to 14 In this embodiment, the heat exchange component 4 is a tube-fin heat exchanger, connecting heat exchange pipeline 16 and heat exchange pipeline 17. Multiple heat dissipation fins 30 are compactly installed inside the heat exchange component 4, arranged in parallel or at a 120-degree angle. The fin spacing and number of tube rows are designed for optimal air resistance, making it more suitable for large-scale chemical equipment. It can save 80%-90% of water and is suitable for application in arid and water-scarce areas of Northwest China.

[0070] The structural parameters of the heat exchange component 4 in this embodiment are as follows.

[0071]

[0072] The calculated heat exchange capacity of the heat exchange component 4 is as follows.

[0073]

[0074] To address the issue of wind and sand protection, this embodiment includes a sand-proof component 19.

[0075] The precooling component 5 is provided with a sand-proof component 19 on its outer side. The sand-proof component 19 is a breathable film that blocks wind and sand, thereby reducing the maintenance rate of the cooling mechanism 6 and extending its service life.

[0076] To address the need to regulate airflow and to shut down the device in cases of strong winds and sandstorms to prevent damage to the cooling mechanism 6, this embodiment includes an airflow regulation component.

[0077] The airflow control component includes a shielding blade 14, a blade drive motor 20, a blade gear 21, and a rack 22. One end of the shielding blade 14 is rotatably connected to the side guard plate 10, one end of the blade drive motor 20 is fixedly connected to the side guard plate 10, one end of the blade gear 21 is fixedly connected to the shielding blade 14, one end of the blade gear 21 is fixedly connected to the power output end of the blade drive motor 20, one end of the rack 22 is slidably connected to the side guard plate 10, and one end of the blade gear 21 meshes with the rack 22.

[0078] Multiple shielding blades 14 are located on one side of the air intake area 18. The blade drive motor 20 can change the angle of the shielding blades 14 on one side by rotating forward and backward, and then drive the angle of all shielding blades 14 to change through the rack 22, so as to adjust the air intake volume. When it is necessary to close the air intake area 18, the shielding blades 14 can be further rotated to seal it.

[0079] To address the issue of a large amount of dust accumulating on one side of the heat exchange component 4 and the precooling component 5 after prolonged operation, this embodiment includes a cleaning assembly.

[0080] The cleaning assembly includes a limiting guide rail 23, a cleaning brush 24, a cleaning motor 27, a sprocket 28, and a chain 29. One end of the limiting guide rail 23 and the cleaning motor 27 is fixedly connected to the side guard plate 10. One end of the multiple sprockets 28 is rotatably connected to the side guard plate 10, and one end of the sprocket 28 is fixedly connected to the power output end of the cleaning motor 27. One end of the chain 29 is drivenly connected to the sprocket 28. One end of the cleaning brush 24 is rotatably connected to the chain 29. One end of the limiting rod 25 is slidably connected to the limiting guide rail 23, and one end of the cleaning brush 24 is slidably connected to the limiting rod 25.

[0081] The chain 29 is arranged in a rectangular pattern with four sprockets 28. The cleaning motor 27 drives the chain 29 to rotate, which in turn drives the cleaning brushes 24, which have bristles on both sides, to move in a rectangular trajectory. After the cleaning brushes 24 move one revolution, the heat exchange components 4 and the pre-cooling components 5 on both sides can be cleaned. The limit rod 25 can keep the cleaning brushes 24 horizontal and prevent them from shaking when sliding left and right. When cleaning the heat exchange components 4, water droplets that have not evaporated in time and splashed onto the heat dissipation fins 30 can also be removed, further preventing the heat dissipation fins 30 from rusting and improving the service life of the components.

[0082] A sealing strip 26 is slidably connected to one side of the side guard plate 10, and one end of the sealing strip 26 is fixedly connected to the chain 29. The sealing strip 26 can seal the slot on one side of the side guard plate 10 while rotating with the chain 29.

[0083] Please see Figures 1 to 4In order to improve the structural strength of the support frame 1, in this embodiment, a bottom diagonal brace 8 and a side support 11 are fixedly connected below the support frame 1 and the side baffle 2. The bottom diagonal brace 8 and the side support 11 can effectively improve the strength of the steel structure and resist wind and sand.

[0084] A ladder 12 is fixedly connected to one side of the side baffle 2, and multiple maintenance walkways 9 are fixedly connected to one side of the support frame 1. Each cooling mechanism 6 has a maintenance walkway 9 on one side, which facilitates maintenance and repair by staff.

[0085] This invention solves the problems of significant decrease in air velocity after passing through the water curtain, affecting heat exchange efficiency, and scaling of heat exchange components caused by water drift, which are problems that exist in traditional air coolers, by optimizing the structure of the precooling component and the shape of the packing unit. By setting up an air valve, the problem of air directly entering the heat exchange component when the precooling component is not in use during winter is solved. Moreover, the structure is stable, the layout is reasonable, the heat exchange efficiency is high, and it is easy to maintain.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, or alterations made by those skilled in the art using the disclosed technical content shall fall within the protection scope of the present invention.
