Description

Technical Field

[0001] This invention relates to the field of water filtration technology for heat exchange equipment, and in particular to a filtration device and method for water in a turbulent flow cooling heat exchange equipment. Background Technology

[0002] With the continuous advancement of industrialization, turbulent flow cooling heat exchange equipment is widely used in various industrial processes. These devices are typically used to transfer heat from one medium to another, achieving heat exchange through the flow of cooling water.

[0003] As operating time increases, scaling will occur in cooling towers. During the operation of the cooling tower, particulate matter in the spray water will continuously accumulate. The deposits will cause the heat exchange tube bundles to easily scale and corrode, reducing the heat exchange efficiency of the cooling tower and even causing equipment damage and inoperability. In addition, the accumulation of impurities will form a dirt layer on the heat exchange surface, reducing heat exchange efficiency and causing the system to be unable to dissipate heat effectively, thus affecting the overall working efficiency and energy utilization rate.

[0004] To ensure the normal operation of turbulent flow cooling heat exchange equipment and improve heat exchange efficiency, the design of the water filtration system is particularly important. Its core task is to efficiently remove particulate matter, suspended solids, sediments, and potentially harmful microorganisms from the cooling water. Existing filter materials, such as fiber filter cartridges and sand layers, while effectively removing large particulate impurities, are prone to clogging, wear, or failure over long-term use, leading to frequent replacement and maintenance, thus increasing operating costs. Furthermore, traditional filtration equipment requires regular cleaning and maintenance during operation; otherwise, the filtration effect will gradually decline. Cleaning may require downtime, affecting normal equipment operation and adding extra labor and time costs. Therefore, this invention addresses the shortcomings of the aforementioned technologies. Summary of the Invention

[0005] Based on the aforementioned technical problems, this invention proposes a filtration device and method for water quality in a wave-flow cooling heat exchanger.

[0006] The present invention proposes a filtration device for water quality in a turbulent flow cooling heat exchanger, comprising a primary filter tank with supporting legs, an inlet pipe fixedly connected to one side of the primary filter tank, a primary filtration mechanism disposed inside the primary filter tank, a backwash filter disposed below the primary filter tank, an aggregating mechanism disposed between the primary filter tank and the backwash filter, and a sterilization mechanism disposed at the output end of the backwash filter.

[0007] The primary filtration mechanism performs primary filtration on the spray water entering the heat exchange equipment to remove larger impurities from the water, and periodically removes the impurities.

[0008] The agglomeration mechanism agglomerates fine impurities in the filtered spray water into large particles, which are then filtered by the backwash filter.

[0009] The sterilization mechanism sterilizes the water and removes bacteria from it.

[0010] Preferably, the primary filtration mechanism includes a conical cage fixedly connected to the inner wall of the primary filtration tank, the output end of the water inlet pipe extends to the upper end of the conical cage, and the outer surface of the conical cage is provided with filter holes in a ring array, the height of the filter holes being 4 / 5 of the height of the conical cage.

[0011] Through the above technical solution, the cleanliness of the water in the heat exchange equipment directly affects the efficiency and service life of the equipment. However, due to the large amount of impurities and particles in the water, problems such as scaling, corrosion, and blockage on the surface of the heat exchanger may occur, thereby affecting the heat exchange efficiency and equipment operation. In order to effectively remove large particulate impurities in the water, such as sand, gravel, and leaves, the spray water discharged from the spray system enters the filter cage through the inlet pipe and filters the large particulate impurities through the filter holes. In order to discharge the impurities later, there is a distance between the position of the filter holes and the inner top wall of the filter holes, thereby realizing the upward conveying and discharge of impurities.

[0012] Preferably, there is a height difference between the lower surface of the conical cage and the inner bottom wall of the primary filter tank, and the inner bottom wall of the primary filter tank is provided with a slanted conical guide groove, and the inner bottom wall of the guide groove is fixedly connected to a flow pipe.

[0013] With the above technical solution, in order to facilitate the rapid flow of filtered spray water, there is an movable gap between the outer surface of the conical cage and the inner wall of the primary filter tank, so that the spray water can be smoothly discharged from the conical cage and discharged from the flow pipe along the guide channel for the next step of processing.

[0014] Preferably, the primary filtration mechanism further includes a discharge pipe fixedly connected to the upper surface of the conical cage. The outer surface of the discharge pipe is rotatably connected to a drive pipe with drive teeth via a bearing. The upper surface of the drive pipe is provided with a discharge hole. A support ring plate is fixedly connected to the inner sidewall of the drive pipe. The upper surface of the support ring plate and the inner top surface of the drive pipe are slidably connected to a sealing plate arranged in a ring array via the cooperation of a guide post and a guide groove.

[0015] With the above technical solution, large particles of impurities such as leaves and sand will affect the filtration effect of the conical cage after they accumulate. In order to periodically discharge the impurities in the conical cage, the water level in the primary filter tank is lower than the lower surface of the conical cage, and the discharge hole is exposed so that the impurities can be discharged from the discharge hole. In order to open the discharge hole, the sealing plate on the support ring plate is rotated when the drive pipe rotates, thereby adjusting the opening size of the discharge hole.

[0016] Preferably, a waterproof motor is fixedly connected to the inner bottom wall of the primary filter tank via a waterproof shell, and a conical spiral conveying rod is rotatably connected to the inner bottom wall of the conical cage via bearings. The outer surface of the output shaft of the waterproof motor is fixedly connected to the lower surface of the conical spiral conveying rod via a coupling. The outer surface of the conical spiral conveying rod is slidably connected to the inner wall of the conical cage and the lower inner wall of the discharge pipe, respectively. A drive screw is rotatably connected to the outer surface of the primary filter tank via a support platform. The drive screw meshes with the drive gear. A drive motor is fixedly connected to one side surface of the support platform, and the outer surface of the output shaft of the drive motor is fixedly connected to the outer surface of the drive screw via a coupling.

[0017] Through the above technical solution, in order to discharge impurities from the conical cage, a waterproof motor drives the conical spiral conveyor rod to rotate. The outer surface of the conical spiral conveyor rod is in contact with the inner wall of the conical cage and the inner wall of the discharge pipe, thereby conveying the impurities upward and discharging them to the outside of the primary filter tank through the discharge hole. In order to control the rotation of the sealing plate, the drive motor drives the drive screw to rotate, which in turn controls the rotation of the drive pipe with drive teeth. This enables the linkage of the sealing plate and realizes the opening and closing control of the discharge hole.

[0018] Preferably, the agglomeration mechanism includes a baffle tube fixedly connected to the lower surface of the flow tube. The outer surface of the baffle tube is fixedly connected to the lower surface of the primary filter tank via a connecting rod. The inner wall of the baffle tube is rotatably connected to a movable shaft via a bearing. A rotating motor is fixedly connected to one side surface of the baffle tube. The outer surface of the output shaft of the rotating motor is fixedly connected to the surface of the movable shaft. A series of grinding discs arranged in a linear array are fixedly sleeved on the outer surface of the movable shaft. The multiple grinding discs are eccentrically sleeved with the movable shaft.

[0019] Through the above technical solution, the spray water initially filtered by the conical cage flows from the flow pipe to the turbulence pipe. In order to aggregate the fine particles in the spray water for subsequent precision filtration, when the spray water flows in the turbulence pipe, the rotating motor drives the movable shaft to rotate, which in turn drives the grinding disc to rotate. Multiple grinding discs are staggered and eccentrically distributed, so that the water flow is turbulent when the grinding disc rotates, which enhances the aggregation effect of the fine particles in the water. At the same time, when the grinding disc contacts the inner wall of the turbulence pipe, it can crush the particles, causing the suspended solids to form larger clumps or sediments, which is beneficial to subsequent precision filtration.

[0020] Preferably, the gathering mechanism further includes a metal corrugated pipe disposed below the turbulence-dispersing pipe. Both ends of the metal corrugated pipe are fixedly connected to stabilizing pipes. One side surface of the stabilizing pipe at one end is fixedly connected to an inlet pipe, and the upper surface of the inlet pipe is fixedly connected to the lower surface of the turbulence-dispersing pipe. The surface of the stabilizing pipe at the other end is fixedly connected to the water inlet of the backwash filter. A booster pump is installed on the outer surface of the inlet pipe. A suspension beam is fixedly connected to the outer surface of the turbulence-dispersing pipe via a bracket. Two sets of reset ropes arranged in a linear array are fixedly connected to the upper surface of the metal corrugated pipe. The two sets of reset ropes are distributed opposite to each other and are both fixedly connected to the outer surface of the suspension beam.

[0021] Through the above technical solution, in order to induce water flow to form disturbances or vortices, and significantly improve the flow velocity and turbulence intensity, so that the tiny particles in the water can more easily collide and aggregate with each other, thereby forming larger clumps or sediments, which are convenient for subsequent filtration and removal, the liquid in the disturbance pipe flows into the metal bellows from the inlet pipe, and the spray water entering the metal bellows is pressurized by the booster pump. The instantaneous high-pressure water flow impacts the metal bellows, which generates longitudinal waves and compresses the tiny particles into clumps. The reset rope is made of steel wire rope and suspends the metal bellows. The two sets of reset ropes can promptly reset the deformed metal bellows, allowing it to propel the spray water and particles in the water forward into the backwash filter. The water then passes through the filter medium to filter out clumps of solid particles, suspended matter and other impurities in the water.

[0022] Preferably, the sterilization mechanism includes a sterilization pipe disposed on one side of the backwash filter, heat dissipation plates are fixedly connected to both sides of the sterilization pipe, water flow pipes with valves are fixedly connected to both ends of the sterilization pipe, and a T-pipe is fixedly connected to one side of the water flow pipe, one end of which is fixedly connected to the output end of the backwash filter.

[0023] Through the above technical solution, the spray water is further precisely filtered by the backwash filter to remove tiny particles, harmful substances, oil, etc., ensuring that the water quality meets high standards. In order to ensure that the cooling system does not experience blockage or corrosion due to microbial growth, the spray water filtered by the backwash filter enters the sterilization pipe through a three-way pipe and a water flow pipe on one side. The sterilization pipe is equipped with UV ultraviolet germicidal lamps, which sterilize the water by ultraviolet light, removing bacteria, algae and other microorganisms. The heat dissipation plate also improves the service life of the sterilization pipe. Then, the disinfected spray water flows through the water flow pipe and three-way pipe on the other side.

[0024] Preferably, one end of one of the three-way pipes is fixedly connected to a circulation pipe, the free end of the circulation pipe is fixedly connected to the backwash pipe of the backwash filter, and the outer surfaces of the primary filter tank, one of the stabilizing pipes, and the turbulence-disrupting pipe are all fixedly connected to a drain pipe.

[0025] Through the above technical solution, in order to clean the filter unit regularly and maintain the efficient operation of the filter, the automatic backwashing device is activated according to the set time interval or water quality monitoring feedback to clean the filter unit, prevent the filter from being blocked, and maintain long-term stable operation. That is, the backwashing filter reverses the water flow direction, flowing from the filter outlet to the inlet, washing away the dirt accumulated on the filter media. In addition, during the backwashing stage, the disinfected spray water flows in reverse from the circulation pipe to the backwashing filter, metal corrugated pipe, turbulence pipe, and primary filter tank, thereby completing the backwashing, and the sewage is discharged from the corresponding drain pipe.

[0026] The present invention proposes a filtration method for a filtration device for water quality in a turbulent flow cooling heat exchanger, comprising the following steps:

[0027] S1. The spray water discharged from the spray system enters the filter cage through the inlet pipe. Large particles of impurities are filtered through the filter holes. The spray water after preliminary filtration flows from the flow pipe to the turbulence pipe along the guide channel.

[0028] S2. When the spray water flows in the turbulence pipe, the rotating motor drives the movable shaft to rotate, which in turn drives the rolling disc to rotate. Multiple rolling discs are staggered and eccentrically distributed, so that the water flow is turbulent when the rolling disc rotates, which enhances the aggregation effect of small particles in the water. At the same time, when the rolling disc contacts the inner wall of the turbulence pipe, it can crush the particles, causing the suspended matter to form larger clumps or sediments.

[0029] S3. At this time, the spray water for turbulence treatment flows into the metal corrugated pipe from the inlet pipe, and the spray water entering the metal corrugated pipe is pressurized by the booster pump. The instantaneous high-pressure water flow impacts the metal corrugated pipe, which generates longitudinal waves and compresses the water. This compresses the small particles into clumps. The reset rope is made of steel wire rope and suspends the metal corrugated pipe. The two sets of reset ropes can promptly reset the deformed metal corrugated pipe, allowing it to propel the spray water and particles in the water forward into the backwash filter. This allows the water to pass through the filter medium and filter out the clumps of solid particles and suspended matter in the water.

[0030] S4. The spray water is further filtered by the backwash filter to remove tiny particles, harmful substances and oil. The filtered spray water enters the sterilization pipe through the T-pipe and water flow pipe on one side. The UV ultraviolet germicidal lamp in the sterilization pipe sterilizes the water and removes bacteria, algae and microorganisms. The disinfected spray water then flows through the water flow pipe and T-pipe on the other side.

[0031] S5. When the water flow resistance in the backwash filter increases, it indicates that a large amount of impurities have accumulated on the filter media. The pressure sensor will detect this change and start the backwash process, that is, the water flow direction of the backwash filter is reversed, flowing from the filter outlet to the inlet, washing away the dirt accumulated on the filter media. In the backwash stage, the disinfected spray water flows in reverse from the circulation pipe to the backwash filter, metal bellows, baffle pipe and primary filter tank, thereby completing the backwash, and the sewage is discharged from the corresponding drain pipe.

[0032] S6. During the backwashing stage, after the water level in the primary filter tank is lower than the lower surface of the conical cage, the drive motor drives the drive screw to rotate, which in turn controls the drive pipe with drive teeth to rotate. When the drive pipe rotates, it drives the sealing plate on the support ring plate to rotate, thereby exposing the opening of the discharge hole. Then, the waterproof motor drives the conical spiral conveyor rod to rotate, and the outer surface of the conical spiral conveyor rod is in contact with the inner wall of the conical cage and the inner wall of the discharge pipe, thereby conveying impurities upward and discharging them to the outside of the primary filter tank through the discharge hole, thus increasing the service life of the conical cage.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. By setting up a primary filtration mechanism, the spray water entering the heat exchange equipment is initially filtered to remove larger impurities. These impurities are periodically removed. During the adjustment process, the spray water discharged from the spray system enters the filter cage through the inlet pipe and filters large particles of impurities through the filter holes. In the backwashing stage, the drive motor drives the drive screw to rotate, which in turn controls the drive tube with drive teeth to rotate. When the drive tube rotates, it drives the sealing plate on the support ring plate to rotate, thereby exposing the opening of the discharge hole. Then, the waterproof motor drives the conical spiral conveyor rod to rotate. The outer surface of the conical spiral conveyor rod is in contact with the inner wall of the conical cage and the inner wall of the discharge pipe, thereby conveying the impurities upward and discharging them to the outside of the primary filter tank through the discharge hole, thus increasing the service life of the conical cage.

[0035] 2. By setting up an agglomeration mechanism, fine particles in the spray water can be agglomerated into clusters for precise filtration. During the adjustment process, the spray water entering the metal corrugated pipe is pressurized by a booster pump. The instantaneous high-pressure water flow impacts the metal corrugated pipe, generating longitudinal waves and compressing it. This compresses the tiny particles into clusters. The reset ropes are made of steel wire rope and suspend the metal corrugated pipe. The two sets of reset ropes can promptly reset the deformed metal corrugated pipe, allowing it to propel the spray water and particles forward into the backwash filter. This allows the water to pass through the filter medium and filter out the clustered solid particles and suspended matter in the water, thereby reducing operating costs.

[0036] 3. By setting up a sterilization mechanism, it can be ensured that the cooling system will not experience blockage or corrosion due to the growth of microorganisms. During the adjustment process, the spray water filtered by the backwash filter enters the sterilization pipe through a three-way pipe and a water flow pipe on one side. UV ultraviolet germicidal lamps are distributed in the sterilization pipe, which sterilizes the water quality by ultraviolet light, removing bacteria, algae and other microorganisms in the water. The heat dissipation plate also improves the service life of the sterilization pipe. Then, the disinfected spray water completes the spray water circulation through the water flow pipe and three-way pipe on the other side, thereby ensuring the cleanliness and safety of the water quality.

[0051] 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.

[0052] Reference Figures 1-13A filtration device for water quality in a turbulent flow cooling heat exchanger includes a primary filter tank 1 with supporting feet, an inlet pipe 2 fixedly connected to one side of the primary filter tank 1, a primary filtration mechanism 4 inside the primary filter tank 1, a backwash filter 3 below the primary filter tank 1, an aggregating mechanism 6 between the primary filter tank 1 and the backwash filter 3, and a sterilization mechanism 7 at the output end of the backwash filter 3.

[0053] The primary filtration unit 4 performs primary filtration on the spray water entering the heat exchange equipment, removing larger impurities from the water and periodically removing the impurities.

[0054] In heat exchange equipment, the cleanliness of the water directly affects the efficiency and service life of the equipment. However, due to the presence of a large number of impurities and particles in the water, problems such as scaling, corrosion, and blockage on the surface of the heat exchanger may occur, thereby affecting the heat exchange efficiency and equipment operation. In order to effectively remove large particulate impurities in the water, such as sand, gravel, and leaves, the primary filtration mechanism 4 includes a conical cage 41 fixedly connected to the inner wall of the primary filter tank 1. The output end of the water inlet pipe 2 extends to the upper end of the conical cage 41. The outer surface of the conical cage 41 is provided with filter holes 42 arranged in a ring array. The height of the filter holes 42 accounts for 4 / 5 of the height of the conical cage 41. The spray water discharged from the spray system enters the filter cage through the water inlet pipe 2 and filters large particulate impurities through the filter holes 42. In order to discharge the impurities later, there is a distance between the position of the filter holes 42 and the inner top wall of the filter holes 42, thereby realizing the upward conveying and discharge of impurities.

[0055] To facilitate rapid flow of filtered spray water, there is a height difference between the lower surface of the conical cage 41 and the inner bottom wall of the primary filter tank 1. The inner bottom wall of the primary filter tank 1 is provided with a slanted conical guide groove 43. The inner bottom wall of the guide groove 43 is fixedly connected to a flow pipe 44. There is a movable gap between the outer surface of the conical cage 41 and the inner wall of the primary filter tank 1, so that the spray water can be smoothly discharged from the conical cage 41 and discharged from the flow pipe 44 along the guide groove 43 for further processing.

[0056] Large particles of impurities, such as leaves and gravel, can accumulate and affect the filtration effect of the conical cage 41. In order to periodically discharge the impurities in the conical cage 41, the primary filtration mechanism 4 also includes a discharge pipe 45 fixedly connected to the upper surface of the conical cage 41. The outer surface of the discharge pipe 45 is rotatably connected to a drive pipe 46 with drive teeth via a bearing. The upper surface of the drive pipe 46 is provided with a discharge hole 47. When the water level in the primary filtration tank 1 is lower than the lower surface of the conical cage 41, the discharge hole 47 is exposed, and the impurities can be discharged from the discharge hole 47. In order to open the discharge hole 47, a support ring plate 48 is fixedly connected to the inner side wall of the drive pipe 46. The upper surface of the support ring plate 48 and the inner top surface of the drive pipe 46 are slidably connected to a sealing plate 49 arranged in a ring array through the cooperation of a guide post and a guide groove. When the drive pipe 46 rotates, it drives the sealing plate 49 on the support ring plate 48 to rotate, thereby adjusting the opening size of the discharge hole 47.

[0057] To facilitate the discharge of impurities from the conical cage 41, a waterproof motor 50 is fixedly connected to the inner bottom wall of the primary filter tank 1 via a waterproof shell. A conical spiral conveying rod 51 is rotatably connected to the inner bottom wall of the conical cage 41 via bearings. The outer surface of the output shaft of the waterproof motor 50 is fixedly connected to the lower surface of the conical spiral conveying rod 51 via a coupling. The outer surface of the conical spiral conveying rod 51 is slidably connected to the inner wall of the conical cage 41 and the lower inner wall of the impurity discharge pipe 45, respectively. A drive screw 52 is rotatably connected to the outer surface of the primary filter tank 1 via a support platform. The drive screw 52 meshes with drive teeth, and the waterproof motor 50 drives the conical spiral conveying rod 51. The conveying rod 51 rotates, and the outer surface of the conical spiral conveying rod 51 is in contact with the inner wall of the conical cage 41 and the inner wall of the impurity discharge pipe 45, thereby conveying impurities upward and discharging them to the outside of the primary filter tank 1 through the impurity discharge hole 47. In order to control the rotation of the sealing plate 49, a drive motor 53 is fixedly connected to one side surface of the support platform. The outer surface of the output shaft of the drive motor 53 is fixedly connected to the outer surface of the drive screw 52 through a coupling. The drive motor 53 drives the drive screw 52 to rotate, which in turn controls the rotation of the drive pipe 46 with drive teeth, thereby realizing the linkage of the sealing plate 49 and realizing the opening and closing control of the impurity discharge hole 47.

[0058] By setting a primary filtration mechanism 4, the spray water entering the heat exchange equipment is subjected to primary filtration to remove larger impurities in the water, and the impurities are periodically removed. During the adjustment process, the spray water discharged from the spray system enters the filter cage through the inlet pipe 2 and filters large particles of impurities through the filter holes 42. During the backwashing stage, the drive motor 53 drives the drive screw 52 to rotate, which controls the drive pipe 46 with drive teeth to rotate. When the drive pipe 46 rotates, it drives the sealing plate 49 on the support ring plate 48 to rotate, thereby exposing the opening of the discharge hole 47. Then, the waterproof motor 50 drives the conical spiral conveyor rod 51 to rotate. The outer surface of the conical spiral conveyor rod 51 is in contact with the inner wall of the conical cage 41 and the inner wall of the discharge pipe 45, thereby conveying the impurities upward and discharging them to the outside of the primary filter tank 1 through the discharge hole 47, thus increasing the service life of the conical cage 41.

[0059] The agglomeration mechanism 6 agglomerates fine impurities in the filtered spray water into large particles, which are then filtered by the backwash filter 3.

[0060] The spray water, initially filtered by the conical cage 41, flows from the flow pipe 44 to the turbulence pipe 61. To aggregate fine particles in the spray water for subsequent precision filtration, the aggregation mechanism 6 includes a turbulence pipe 61 fixedly connected to the lower surface of the flow pipe 44. The outer surface of the turbulence pipe 61 is fixedly connected to the lower surface of the primary filter tank 1 via a connecting rod. A movable shaft 62 is rotatably connected to the inner wall of the turbulence pipe 61 via a bearing. A rotating motor 63 is fixedly connected to one side surface of the turbulence pipe 61. The outer surface of the output shaft of the rotating motor 63 is fixedly connected to the surface of the movable shaft 62. The outer surface is fixedly fitted with a linear array of grinding discs 64. The multiple grinding discs 64 are eccentrically connected to the movable shaft 62. When the sprayed water flows in the turbulence pipe 61, the rotating motor 63 drives the movable shaft 62 to rotate, which in turn drives the grinding discs 64 to rotate. The multiple grinding discs 64 are staggered and eccentrically distributed, so that the rotation of the grinding discs 64 generates turbulence in the water flow, which enhances the aggregation effect of small particles in the water. At the same time, when the grinding discs 64 come into contact with the inner wall of the turbulence pipe 61, they can crush the particles, causing the suspended solids to form larger clumps or sediments, which is beneficial for subsequent precision filtration.

[0061] To induce turbulence or eddies in the water flow, significantly increasing the flow velocity and turbulence intensity, and allowing tiny particles in the water to collide and aggregate more easily, forming larger clumps or sediments for easier subsequent filtration and removal, the agglomeration mechanism 6 also includes a metal bellows 65 positioned below the turbulence pipe 61. Stabilizing pipes 66 are fixedly connected to both ends of the metal bellows 65. An inlet pipe 67 is fixedly connected to one side of one end of the stabilizing pipe 66, with its upper surface fixedly connected to the lower surface of the turbulence pipe 61. The surface of the other end of the stabilizing pipe 66 is fixedly connected to the inlet of the backwash filter 3. A booster pump 68 is installed on the outer surface of the inlet pipe 67. A suspension beam 69 is fixedly connected to the outer surface of the turbulence pipe 61 via a bracket. The upper surface of the metal bellows 65 is fixedly connected to the inlet. Two sets of reset ropes 691 are linearly arrayed and fixedly connected to the outer surface of the suspension beam 69. The liquid in the turbulence pipe 61 flows into the metal bellows 65 from the inlet pipe 67 and is pressurized by the booster pump 68. The instantaneous high-pressure water flow impacts the metal bellows 65, causing longitudinal waves and compression, which can compress small particles into clumps. The reset ropes 691 are made of steel wire rope and suspend the metal bellows 65. The two sets of reset ropes 691 can promptly reset the deformed metal bellows 65, allowing it to propel the spray water and particles in the water forward into the backwash filter 3. The water then passes through the filter medium to filter out clumps of solid particles, suspended matter, and other impurities in the water.

[0062] By setting up the agglomeration mechanism 6, fine particles in the spray water can be agglomerated into clusters for precise filtration. During the adjustment process, the spray water entering the metal bellows 65 is pressurized by the booster pump 68. The instantaneous high-pressure water flow impacts the metal bellows 65, causing longitudinal waves and compression, which in turn compresses the tiny particles into clusters. The reset rope 691 is made of steel wire rope and suspends the metal bellows 65. The two sets of reset ropes 691 can promptly reset the deformed metal bellows 65, allowing it to propel the spray water and particles forward into the backwash filter 3. This allows the water to pass through the filter medium and filter out the clustered solid particles and suspended matter in the water, thereby reducing operating costs.

[0063] Among them, the sterilization unit 7 sterilizes the water and removes bacteria from the water.

[0064] The backwash filter 3 further refines the spray water to remove tiny particles, harmful substances, oil, etc., ensuring that the water quality meets high standards. To ensure that the cooling system does not experience blockage or corrosion due to microbial growth, the sterilization mechanism 7 includes a sterilization pipe 71 located on one side of the backwash filter 3. Heat dissipation plates 72 are fixedly connected to both sides of the sterilization pipe 71. Water flow pipes 73 with valves are fixedly connected to the upper surfaces of both ends of the sterilization pipe 71. A three-way pipe 74 is fixedly connected to one side of the water flow pipe 73. One end of one of the three-way pipes 74 is fixedly connected to the output end of the backwash filter 3. The spray water filtered by the backwash filter 3 enters the sterilization pipe 71 through the three-way pipe 74 and the water flow pipe 73 on one side. UV ultraviolet germicidal lamps are distributed inside the sterilization pipe 71 to sterilize the water quality by ultraviolet light, removing bacteria, algae, and other microorganisms in the water. The heat dissipation plate 72 also improves the service life of the sterilization pipe 71. Then, the disinfected spray water completes the spray water circulation through the water flow pipe 73 and the three-way pipe 74 on the other side.

[0065] To regularly clean the filter unit and maintain its efficient operation, one end of another three-way pipe 74 is fixedly connected to a circulation pipe 75. The free end of the circulation pipe 75 is fixedly connected to the backwash pipe of the backwash filter 3. The outer surfaces of the primary filter tank 1, one of the stabilizing pipes 66, and the turbulence pipe 61 are all fixedly connected to a drain pipe 76. According to the set time interval or water quality monitoring feedback, the automatic backwashing device is activated to clean the filter unit, prevent the filter from being blocked, and maintain long-term stable operation. That is, the water flow direction of the backwash filter 3 is reversed, flowing from the filter outlet to the inlet, washing away the dirt accumulated on the filter media. During the backwashing stage, the disinfected spray water flows in reverse from the circulation pipe 75 to the backwash filter 3, the metal corrugated pipe 65, the turbulence pipe 61, and the primary filter tank 1, thereby completing the backwashing. The sewage is discharged from the corresponding drain pipe 76.

[0066] By setting up the sterilization mechanism 7, it can be ensured that the cooling system will not experience blockage or corrosion due to the growth of microorganisms. During the adjustment process, the spray water filtered by the backwash filter 3 enters the sterilization pipe 71 through the three-way pipe 74 and the water flow pipe 73 on one side. The sterilization pipe 71 is equipped with UV ultraviolet germicidal lamps, which sterilize the water quality by using ultraviolet light to remove bacteria, algae and other microorganisms in the water. The heat dissipation plate 72 also improves the service life of the sterilization pipe 71. Then, the disinfected spray water completes the spray water circulation through the water flow pipe 73 and the three-way pipe 74 on the other side, thereby ensuring the cleanliness and safety of the water quality.

[0067] Reference Figures 1-13 A filtration method for a filtration device for water quality in a wave-turbulence cooling heat exchanger includes the following steps:

[0068] S1. The spray water discharged from the spray system enters the filter cage through the inlet pipe 2 and filters large particles of impurities through the filter holes 42. The spray water after preliminary filtration flows from the flow pipe 44 to the turbulence pipe 61 along the guide channel 43.

[0069] S2. When the spray water flows in the turbulence pipe 61, the rotating motor 63 drives the movable shaft 62 to rotate, which in turn drives the grinding disc 64 to rotate. The multiple grinding discs 64 are staggered and eccentrically distributed, so that the water flow is turbulent when the grinding discs 64 rotate, which enhances the aggregation effect of small particles in the water. At the same time, when the grinding discs 64 come into contact with the inner wall of the turbulence pipe 61, they can crush the particles, causing the suspended matter to form larger clumps or sediments.

[0070] S3. At this time, the spray water with turbulence treatment flows into the metal bellows 65 from the inlet pipe 67, and the spray water entering the metal bellows 65 is pressurized by the booster pump 68. The instantaneous high-pressure water flow impacts the metal bellows 65, which will generate longitudinal waves and compress it. This can compress the small particles into clumps. The reset rope 691 is made of steel wire rope and suspends the metal bellows 65. The two sets of reset ropes 691 can promptly reset the deformed metal bellows 65, so that it can propel the spray water and particles in the water forward into the backwash filter 3, so that the water flow can filter out the clumps of solid particles and suspended matter in the water through the filter medium.

[0071] S4. The spray water is further filtered by the backwash filter 3 to remove small particles, harmful substances and oil stains in the water. The filtered spray water enters the sterilization pipe 71 through the three-way pipe 74 and the water flow pipe 73 on one side. The UV ultraviolet germicidal lamp in the sterilization pipe 71 sterilizes the water quality and removes bacteria, algae and microorganisms in the water. Then the disinfected spray water completes the flow of spray water through the water flow pipe 73 and the three-way pipe 74 on the other side.

[0072] S5. When the water flow resistance in the backwash filter 3 increases, it indicates that a large amount of impurities have accumulated on the filter medium. The pressure sensor will detect this change and start the backwash process, that is, the water flow direction of the backwash filter 3 is reversed, flowing from the outlet of the filter to the inlet, washing away the dirt accumulated on the filter medium. In the backwash stage, the disinfected spray water flows in reverse from the circulation pipe 75 to the backwash filter 3, the metal corrugated pipe 65, the turbulence pipe 61, and the primary filter tank 1, thereby completing the backwash. The sewage is discharged from the corresponding drain pipe 76.

[0073] S6. During the backwashing stage, after the water level in the primary filter tank 1 is lower than the lower surface of the conical cage 41, the drive motor 53 drives the drive screw 52 to rotate, which in turn controls the drive pipe 46 with drive teeth to rotate. When the drive pipe 46 rotates, it drives the sealing plate 49 on the support ring plate 48 to rotate, thereby exposing the opening of the discharge hole 47. Then, the waterproof motor 50 drives the conical spiral conveyor rod 51 to rotate. The outer surface of the conical spiral conveyor rod 51 is in contact with the inner wall of the conical cage 41 and the inner wall of the discharge pipe 45, thereby conveying the impurities upward and discharging them to the outside of the primary filter tank 1 through the discharge hole 47, thus increasing the service life of the conical cage 41.

[0074] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A filtration method for a filtration device applied to the water quality of the turbulent flow cooling heat exchanger as described in claim 5, characterized in that: Includes the following steps: S1. The spray water discharged from the spray system enters the filter cage through the inlet pipe (2) and filters large particles of impurities through the filter holes (42). The spray water after preliminary filtration flows from the flow pipe (44) to the turbulence pipe (61) along the guide channel (43). S2. When the spray water flows in the turbulence pipe (61), the rotating motor (63) drives the movable shaft (62) to rotate, which in turn drives the grinding disc (64) to rotate. The multiple grinding discs (64) are staggered and eccentrically distributed, so that the water flow generates turbulence when the grinding discs (64) rotate, which enhances the aggregation effect of small particles in the water. At the same time, when the grinding discs (64) come into contact with the inner wall of the turbulence pipe (61), they can crush the particles, causing the suspended matter to form larger clumps or sediments. S3. At this time, the spray water treated by the turbulence flows into the metal bellows (65) from the inlet pipe (67), and the spray water entering the metal bellows (65) is pressurized by the booster pump (68). The instantaneous high-pressure water flow impacts the metal bellows (65), which will generate longitudinal waves and compress it. This can compress the small particles into a clump. The reset rope (691) is made of steel wire rope and suspends the metal bellows (65). Thus, the two sets of reset ropes (691) can promptly reset the deformed metal bellows (65), so that the spray water and particles in the water can be pushed forward and flow into the backwash filter (3). This allows the water to pass through the filter medium to filter out the clumps of solid particles and suspended matter in the water. S4. The spray water is further filtered by the backwash filter (3) to remove small particles, harmful substances and oil stains in the water. The filtered spray water enters the sterilization pipe (71) through the three-way pipe (74) and water flow pipe (73) on one side. The UV ultraviolet sterilization lamp in the sterilization pipe (71) sterilizes the water quality and removes bacteria, algae and microorganisms in the water. Then the disinfected spray water completes the flow of spray water through the water flow pipe (73) and three-way pipe (74) on the other side. S5. When the water flow resistance in the backwash filter (3) increases, it indicates that a large amount of impurities have accumulated on the filter medium. The pressure sensor will detect this change and start the backwash process, that is, the water flow direction of the backwash filter (3) is reversed and flows from the outlet of the filter to the inlet, washing away the dirt accumulated on the filter medium. In the backwash stage, the disinfected spray water flows in reverse from the circulation pipe (75) to the backwash filter (3), the metal corrugated pipe (65), the turbulence pipe (61), and the primary filter tank (1), thereby completing the backwash. The sewage is discharged from the corresponding drain pipe (76). S6. During the backwashing stage, after the water level in the primary filter tank (1) is lower than the lower surface of the conical cage (41), the drive screw (52) is driven to rotate by the drive motor (53), which controls the drive tube (46) with drive teeth to rotate. When the drive tube (46) rotates, it drives the sealing plate (49) on the support ring plate (48) to rotate, thereby exposing the opening of the discharge hole (47). Then the waterproof motor (50) drives the conical spiral conveyor (51) to rotate. The outer surface of the conical spiral conveyor (51) is attached to the inner wall of the conical cage (41) and the inner wall of the discharge pipe (45), thereby conveying the impurities upward and discharging them to the outside of the primary filter tank (1) through the discharge hole (47), thus increasing the service life of the conical cage (41).
