Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and more specifically, to a cooling tower. Background Technology

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from the system and release it into the atmosphere to lower the water temperature. Its cooling effect is achieved by the heat exchange between water and air flow to generate steam. The steam evaporates and carries away the heat, thus achieving heat dissipation through evaporation, convection, and radiation. This process dissipates waste heat generated in industrial processes or refrigeration and air conditioning systems to lower the water temperature and ensure the normal operation of the system. The device is generally cylindrical, hence the name cooling tower.

[0003] Cooling towers are commonly used industrial equipment, widely applied in air conditioning cooling systems, refrigeration systems, injection molding, leather making, foaming, power generation, steam turbines, aluminum profile processing, air compressors, and industrial water cooling. Their most common applications are in air conditioning cooling, refrigeration, and the plastics and chemical industries. Specifically, as a product used in the air conditioning industry, they are found in shopping malls, hotels, office buildings, and residential buildings.

[0004] Currently, cooling towers on the market are broadly classified into open towers and closed towers, with open towers being the most widely used. Open towers spray hot cooling water from spray pipes into the packing material, allowing direct contact with the air for heat exchange. This type of tower is inexpensive, has good heat exchange efficiency, and is widely applicable, but it is noisy and large in size. Because of the direct contact with air, atmospheric dust can be incorporated into the cooling water, causing sediment buildup at the bottom, requiring regular cleaning of the tower's interior.

[0005] The problem of sludge and debris accumulating in existing cooling towers is a technical problem that this invention urgently needs to solve. Summary of the Invention

[0006] This invention provides a cooling tower to solve the problem of easy accumulation of sludge and debris in existing cooling towers.

[0007] To achieve the above objectives, the present invention provides a cooling tower, including a water collection tray disposed at the bottom of the cooling tower and a sludge removal component disposed within the water collection tray. The sludge removal component is used to clean sludge and debris from the water collection tray. The sludge removal component includes: an active rotating member rotatably disposed within the water collection tray; and a flexible stirring member located within the water collection tray, wherein a first end of the flexible stirring member is drivenly connected to the active rotating member, and a second end of the flexible stirring member is connected to the inner wall of the water collection tray. The active rotating member drives the flexible stirring member to move by rotating.

[0008] Furthermore, it also includes: an elastic element connected to the inner wall of the water collection tray; and a second end of the flexible stirring element fixedly connected to the elastic element.

[0009] Furthermore, there are multiple flexible stirring elements, and the first end of all the flexible stirring elements is drivenly connected to the active rotating element;

[0010] There are multiple elastic elements, and each elastic element corresponds to a flexible stirring element. The second end of each flexible stirring element is connected to an elastic element.

[0011] Furthermore, multiple elastic elements are arranged circumferentially along the inner wall of the water collection tray.

[0012] Furthermore, there is one active rotating component, which is located in the middle of the water collection plate and rotates along its own axis.

[0013] Furthermore, the elastic element is a spring.

[0014] Furthermore, the flexible stirring element is a stirring rope.

[0015] Furthermore, the cooling tower includes an inlet pipe, a makeup water pipe, a sewage pipe, an outlet water pipe, and a bypass pipe;

[0016] The sewage pipe is connected to the water collection tray, and the sewage pipe is used to discharge sewage from the water collection tray;

[0017] The bypass pipeline adds chemicals into the cooling tower.

[0018] Furthermore, the cooling tower has a shutdown cleaning mode, in which:

[0019] The inlet pipe is closed, the outlet pipe is closed, the bypass pipe is closed, the sewage pipe is open, the water supply pipe is open, and the active rotating component is in operation;

[0020] After the first time T1 of operation, the active rotating component stops, the water supply pipeline closes, and the sewage discharge pipeline closes.

[0021] Furthermore, the cooling tower has a non-stop sludge removal mode, in which:

[0022] The sewage pipe is opened, the water supply pipe is opened, and the active rotating component is in operation;

[0023] After the second time T2, the active rotating component stops and the sewage pipe is closed.

[0024] Furthermore, the cooling tower has packing material inside, and the water from the inlet pipe enters the packing material to exchange heat with the air;

[0025] The cooling tower has a shutdown and packing cleaning mode. In the shutdown and packing cleaning mode:

[0026] The water supply pipeline is closed, the water inlet pipeline is closed, the water outlet pipeline is closed, the bypass pipeline is open, and the sewage discharge pipeline is open;

[0027] After the third time period T3, the bypass pipeline is closed, the sewage pipeline is closed, the water supply pipeline is opened, the water inlet pipeline is opened, and the water outlet pipeline is opened.

[0028] Furthermore, the cooling tower has a non-stop packing cleaning mode, in which:

[0029] The water supply pipeline is closed, the bypass pipeline is opened, and the sewage pipeline is opened;

[0030] After the fourth time period T4, the bypass pipeline is closed, the sewage pipeline is closed, and the water supply pipeline is opened.

[0031] Furthermore, the cooling tower also includes a packing cleaning controller;

[0032] The controller controls the cooling tower to enter either a shutdown mode or a non-shutdown mode for cleaning the packing material, based on the relationship between the outlet water temperature and the wet-bulb temperature of the cooling tower.

[0033] Furthermore, the cooling tower includes:

[0034] A noise-reducing filter component is disposed above the water collection tray;

[0035] After exchanging heat with the air, the water droplets fall onto the noise-reducing filter component and then flow into the water collection tray.

[0036] Furthermore, the noise reduction filtering component includes:

[0037] A filter element is used to receive dripping water. The surface of the filter element is made of noise-reducing material, and the interior of the filter element is made of material that filters impurities.

[0038] A housing, which is connected inside the cooling tower, and which supports and connects the filter element.

[0039] Furthermore, the housing is slidably connected inside the cooling tower, and the housing can be slidably pulled out from inside the cooling tower.

[0040] A sludge-removing component has been added to the water collection basin at the bottom of the cooling tower to remove sludge and debris, eliminating the need for regular manual cleaning, reducing labor costs, and improving the efficiency of cooling tower maintenance and cleaning. In this invention, when sludge removal is required, an active rotating component within the water collection basin rotates, driving a flexible agitator. The agitation trajectory and vibration generated by the flexible agitator dislodge the deposited sludge, dissolving it in the water for subsequent centralized discharge. The flexible agitator can both directly impact and break up the sludge and vibrate it, resulting in a more prominent and significant sludge-removing effect. Compared to other sludge-removing structures, this invention's structure is more effective and faster for removing the deposited sludge at the bottom of cooling towers. Attached Figure Description

[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0050] See Figures 1 to 5 As shown, according to an embodiment of the present invention, a cooling tower is provided, the cooling tower including a water collection tray 10 disposed at the bottom of the cooling tower and a sludge removal component 20 disposed within the water collection tray 10, the sludge removal component 20 being used to clean sludge and debris within the water collection tray 10.

[0051] The dredging component 20 includes an active rotating component 21 and a flexible agitator 22. The active rotating component 21 is rotatably disposed in the water collection pan 10. The flexible agitator 22 is located in the water collection pan 10. The first end of the flexible agitator 22 is driven to be connected to the active rotating component 21, and the second end of the flexible agitator 22 is connected to the inner wall of the water collection pan 10. The active rotating component 21 drives the flexible agitator 22 to move by rotating.

[0052] A sludge-removing component is added to the water collection basin at the bottom of the cooling tower to remove sludge and debris, eliminating the need for regular manual cleaning, reducing labor costs, and improving the maintenance and cleaning efficiency of the cooling tower. In this invention, when sludge removal is required, the active rotating component 21 in the water collection basin rotates, driving the flexible stirring component 22. The stirring trajectory and vibration generated by the flexible stirring component can agitate the deposited sludge, dissolving it in the water for centralized discharge. The flexible stirring component can both directly impact and break up the sludge and generate vibration to agitate it, resulting in a more prominent and significant sludge-removing effect. Compared to other sludge-removing structures, the structure of this invention is more effective and faster for removing the deposited sludge at the bottom of the cooling tower.

[0053] See Figure 2 and Figure 3 The cooling tower also includes an elastic element 23, which is connected to the inner wall of the water collection tray 10; the second end of the flexible stirring element 22 is fixedly connected to the elastic element 23.

[0054] When the active rotating component 21 drives the flexible stirring component 22 to move, the second end of the flexible stirring component stretches the elastic component. The elastic component has a certain deformation, so the flexible stirring component will form a larger stirring range when it is driven, thus improving the dredging efficiency.

[0055] Considering the large area of ​​the water collection tray and the existence of certain dead corners, the number of flexible agitators and elastic components is set to be multiple, so that every corner of the water collection tray can be agitated and cleared.

[0056] Combination Figure 3 As shown, there are multiple flexible stirring elements 22, and the first end of all flexible stirring elements 22 is driven to be connected to the active rotating element 21.

[0057] There are multiple elastic elements 23, and each elastic element 23 corresponds to a flexible stirring element 22. Each flexible stirring element 22 has an elastic element 23 connected to its second end.

[0058] To maximize the structural effect, each elastic component is equipped with a flexible agitator. This ensures that the movement trajectories of the two flexible agitators do not interfere with each other, allowing each to complete its agitation and vibration functions independently. This makes the sludge removal work of the water collection pan more efficient and faster.

[0059] Preferably, a plurality of elastic elements 23 are spaced apart circumferentially along the inner wall of the water collecting pan 10. A gap is provided between the elastic elements 23 to prevent two adjacent flexible stirring elements from interfering with each other during movement. The shape of the water collecting pan matches the spacing of the elastic elements.

[0060] To simplify the structure and reduce costs, in this embodiment, there is only one active rotating component 21, which is located in the middle of the water collection tray 10. The active rotating component 21 rotates along its own axis. By using one active rotating component 21 to drive the movement of all the flexible stirring components 22, only one motor 21a is needed to drive the rotation of the active rotating component 21. This eliminates the need for additional motor structures, simplifying the structure and facilitating assembly, maintenance, and cost reduction. The shape of the active rotating component 21 can be... Figure 3 Cam-shaped, or can be Figure 4 The linkage-shaped active rotating component 21 rotates around the center of the motor 21a.

[0061] Preferably, the elastic element 23 is a spring. The structure of the spring can adapt to the movement trajectory of the flexible stirring component. The spring has a large deformation and is more flexible, which can maximize the movement range of the flexible stirring component.

[0062] In this embodiment, the flexible stirring element 22 is a stirring rope. Combined with... Figure 4 As shown, when the active rotating component 21 rotates to its maximum position on both sides, the stirring rope moves accordingly, and the spring at the end of the stirring rope is also stretched. Figure 4 The shaded area A in the diagram represents the swinging area (range of motion) of the stirring rope. The faster the motor speed, the greater the frequency of the stirring rope's back-and-forth swing, thus shaking the sludge at the bottom of the collection pan back into the water. The structure of the stirring rope is ideally suited for cleaning and shaking the sludge in the collection pan, and its combination with the motor speed can meet various needs.

[0063] Combination Figure 1 As shown, the cooling tower includes an inlet pipe 31, a makeup water pipe 32, a sewage discharge pipe 33, an outlet water pipe 34, and a bypass pipe 35.

[0064] The sewage pipe 33 is connected to the water collection tray 10 and is used to discharge the sewage in the water collection tray 10; the bypass pipe 35 is used to add chemicals into the cooling tower.

[0065] Each of the inlet pipe 31, the water supply pipe 32, the sewage pipe 33, the outlet pipe 34, and the bypass pipe 35 is equipped with its own valve. The valve can control the opening or closing of each pipe. The valve structure is existing technology and will not be described in detail.

[0066] It should be noted that the bypass pipe 35 has a chemical dosing tank 35a installed along its path to provide power for adding chemicals to the cooling water. When the valve of the bypass pipe 35 is opened, the water pressure can be used to carry the chemicals in the dosing tank 35a upwards to the cooling water in the inlet pipe 31, and then sprayed onto the packing material by the spray head 31a to remove scale.

[0067] Water supply pipe 32 is always connected to the municipal water supply (i.e., tap water), so there is always water pressure regardless of whether the cooling tower is on or off. Water outlet pipe 34 is connected to the chiller unit. The outlet of water outlet pipe 34 is equipped with a filter screen, and the water flowing out of the outlet of water outlet pipe 34 is cooled, clean cooling water, which is a usable water resource.

[0068] The drain outlet of drain pipe 33 is usually closed, and is only opened when the cooling tower needs cleaning to discharge turbid water and silt from the bottom of the collection basin. The drain outlet usually leads to a drainage ditch on the ground.

[0069] The cooling tower has a shutdown cleaning mode. In shutdown cleaning mode:

[0070] The inlet pipe 31 is closed, the outlet pipe 34 is closed, the bypass pipe 35 is closed, the sewage pipe 33 is open, the water supply pipe 32 is open, and the active rotating component 21 is in operation;

[0071] After the first time T1 of operation, the active rotating component 21 stops, the water supply pipe 32 closes, and the sewage discharge pipe 33 closes.

[0072] The cooling tower has a non-stop sludge cleaning mode. In non-stop sludge cleaning mode:

[0073] Sewage pipe 33 is opened, water supply pipe 32 is opened, and active rotating component 21 is in operation;

[0074] After the second time T2, the active rotating component 21 stops and the sewage pipe 33 is closed.

[0075] The second time T2 is greater than the first time T1.

[0076] The cooling tower contains packing material 40. Water from the inlet pipe 31 enters the packing material 40 and exchanges heat with the air. Cooling water enters the spray head 31a from the inlet pipe 31 and is sprayed out from the spray head 31a, entering the packing material 40 to exchange heat with the air. At the same time, air inlets (not labeled) are installed around the packing material 40, and a fan draws air into the packing material 40 through the air inlets to exchange heat with the cooling water.

[0077] The cooling tower has a shutdown and packing cleaning mode. In the shutdown and packing cleaning mode:

[0078] Water supply pipe 32 is closed, water inlet pipe 31 is closed, water outlet pipe 34 is closed, bypass pipe 35 is opened, and sewage pipe 33 is opened;

[0079] After the third time period T3, the bypass pipe 35 is closed, the sewage pipe 33 is closed, the water supply pipe 32 is opened, the water inlet pipe 31 is opened, and the water outlet pipe 34 is opened.

[0080] The cooling tower has a non-stop packing cleaning mode. In this mode:

[0081] Water supply pipe 32 is closed, bypass pipe 35 is opened, and sewage pipe 33 is opened;

[0082] After the fourth time T4 is completed, bypass pipe 35 is closed, sewage pipe 33 is closed, and water supply pipe 32 is opened.

[0083] Since this invention already possesses an automatic sludge removal function, there is no need to install inspection doors and inspection compartments for the cooling tower, thus reducing the tower's volume. The packing 40 can be installed and replaced conveniently and quickly via the packing replacement door using a pull-out method. If maintenance of other components is required, the packing can be quickly removed through the packing replacement door.

[0084] Current methods for cleaning cooling towers mostly involve shutting down the system and manual cleaning. Shutting down a cooling tower requires shutting down the entire air conditioning system. For large units, frequent shutdowns and restarts not only increase energy consumption but also damage the equipment. Therefore, manual cleaning is not very frequent. A strategy of cleaning without shutting down the system can only be achieved through automated cleaning, which is one of the core innovations of this invention. It allows cleaning to be completed at any time without affecting the unit.

[0085] When the cooling tower is shut down, both the inlet and outlet water pipes are closed; otherwise, the cooling tower continues to operate. Cleaning requires removing sludge, so the drain pipe is opened whenever cleaning begins, regardless of whether the tower is shut down. Clean water is used for cleaning the cooling tower, and the water supply pipe is opened whenever cleaning is required. The bypass pipe is used to flush chemicals into the inlet pipe, which then fall from the top of the packing material to clean it. It is unnecessary to open the bypass pipe when only cleaning the sump; the bypass pipe is only opened when cleaning the packing material. Cleaning the sludge in the sump requires a power source to drive the agitator rope, powered by a motor.

[0086] The fourth time, T4, is greater than the third time, T3. When cleaning the packing material during shutdown, tap water (municipal water supply) is used, and the water pressure is relatively low, allowing the chemicals to remain on the packing material for a longer period. When cleaning the packing material without shutting down the system, tap water flushes the chemicals into the cooling water, which then acts on the packing material. Cooling water is not as clean as tap water, and both water flows have higher pressure and flow rates. This dilutes the chemical concentration and reduces the residence time, resulting in a less effective and longer cleaning process without shutting down the system. Therefore, T4 is greater than T3.

[0087] Due to the special nature of the water supply pipeline, it is activated when the water level in the collection pan is lower than the design value in non-cleaning conditions.

[0088] The cooling tower also includes a packing cleaning controller; the controller controls the cooling tower to enter either a shutdown packing cleaning mode or a non-shutdown packing cleaning mode based on the relationship between the cooling tower's outlet water temperature and wet bulb temperature.

[0089] The automatic cleaning system allows for manually set cleaning cycles, enabling unattended operation. The packing material cleaning decision logic includes two methods: one is to activate it at set times; the other is to activate it by comparing the outlet water temperature and wet-bulb temperature monitored by the controller.

[0090] The two cleaning modes, namely the shutdown cleaning mode and the non-shutdown cleaning mode, are only different in that they target different objects and can be started simultaneously. The idea behind the non-shutdown cleaning mode is to use clean water from the water supply pipe 32 to replace the dirty cooling water.

[0091] Combination Figure 5 As shown, the cooling tower includes a noise reduction filter component 50, which is disposed above the water collection tray 10.

[0092] After exchanging heat with the air, the water droplets fall onto the noise reduction filter component 50 and then flow into the water collection tray 10.

[0093] The noise reduction here refers to the lower and quieter sound produced by water droplets falling directly onto the water surface of the collection tray. The noise reduction filter component 50 reduces noise in two ways: first, when water droplets fall onto the material of the noise reduction filter component 50, the sound produced when the water droplets fall is quieter; second, the noise reduction filter component 50 can reduce the kinetic energy of the falling water droplets, thereby making the sound of the water droplets entering the collection tray quieter.

[0094] The noise reduction and filtration component 50 includes a filter element 51 and a housing 52. The filter element 51 is used to receive dripping water, and its surface is made of noise reduction material, while the interior of the filter element 51 is made of material that filters impurities. The housing 52 is connected inside the cooling tower and supports the filter element 51.

[0095] The surface of filter element 51 is made of noise-reducing material. The door 54 can be made of various materials or have different structures; for example, both the door 54 and the surface of filter element 51 can be made of noise-reducing material. The door serves to support the filter element and allow water to pass through. The door 54 can also be a filter screen and does not perform filtration itself. The door is made of stainless steel, and filter element 51 is a fiber filter element, such as glass fiber, metal fiber, polypropylene fiber, or polyester fiber.

[0096] Filter element 51 can be made of glass fiber, one of the most common and highest-performing filter media available today. It is suitable for use in hydraulic systems, performing depth filtration with a filtration accuracy range of 1-30µm. It is less affected by changes in the working environment, has low flow resistance, and a strong dirt-holding capacity. Even beyond the specified differential pressure range, it maintains a high ability to remove fine particles. It has good chemical resistance but is not suitable for water-glycol mixtures.

[0097] Filter element 51 can also be made of organic chemical fibers, which are also excellent filter media. They offer a filtration accuracy range of 3-30µm, deep filtration, can withstand high pressure differentials, have low flow resistance, and a large dirt-holding capacity. They possess strong chemical resistance, making them particularly suitable for emulsion-based synthetic hydraulic fluids. They are tear-resistant, but their filtration accuracy varies slightly with temperature.

[0098] Plant fiber was the earliest used fiber filter media. Due to its uneven pore size distribution, its filtration accuracy cannot be expressed in absolute terms, but only in nominal terms. Its filtration efficiency is relatively low, but it is widely used in various fields due to its lower cost and wider operating temperature range compared to glass fiber. The nominal accuracy range is generally 10-100µm. The thickness of the fibers affects the filter media's accuracy and oil flow capacity. The finer the fibers, the higher the accuracy; the more pores, the smaller the pressure drop. The fibers are bonded together with resin. Filter media with uniform bonding has high resistance to breakage and will not break or detach under pressure, flow fluctuations, temperature, or aging. It does not undergo chemical reactions, does not expand, and is not limited by shelf life. Currently, composite fibers are most commonly used, typically consisting of 3-5 layers, with the middle filtration layer made of short fibers and the inner and outer protective layers made of long fibers.

[0099] The housing 52 is slidably connected inside the cooling tower and can be slidably pulled out of the cooling tower. Casters are installed at the bottom of the housing 52, allowing it to be pulled out of the cooling tower like a drawer using the handle 53 for cleaning or replacement. The surface of the filter element 51 is made of noise-reducing material, the same material as the door 54, while the bottom is made of filtration material such as quartz sand, filtering out larger impurities in the cooling water, such as algae and large particles of sand.

[0100] The embodiments of the present invention have the following technical effects and advantages:

[0101] Firstly, the cleaning space for the cooling tower occupies at least one-third of the tower's volume. By replacing manual cleaning with an automated cleaning system, this cleaning space can be reduced, potentially decreasing the cooling tower's volume by one-quarter. Furthermore, the automated cleaning system can operate without shutting down the cooling tower.

[0102] Secondly, adding a noise-reducing filter between the cooling tower packing and the water collection tray can reduce the noise generated by falling water droplets and filter out large impurities, making it a multi-purpose device.

[0103] Finally, the automatic cleaning system combines physical and chemical cleaning methods: chemical cleaning of filler material is achieved through the addition of chemicals, while physical cleaning of the bottom is achieved through vibration.
