Description

Technical Field

[0001] The present invention relates to the technical field of water quality filtration of heat exchange equipment, and in particular to a device and method for filtering water quality of a heat exchange equipment by using a disturbed wave flow to cool the water. Background Art

[0002] With the continuous advancement of industrialization, disturbed flow cooling heat exchange equipment has been widely used in various industrial processes. These devices are usually used to transfer heat from one medium to another, and achieve heat exchange through the flow of cooling water.

[0003] As the operating time increases, scaling will occur in the cooling tower. During the operation of the cooling tower, the particles in the spray water are continuously deposited. The deposits cause the heat exchange tube bundle to easily scale and corrode, reducing the heat exchange efficiency of the cooling tower and even causing the equipment to be damaged and unable to operate. The accumulation of impurities will form a dirt layer on the heat exchange surface, reducing the heat exchange efficiency and causing the system to be unable to effectively dissipate heat, thereby affecting the overall work efficiency and energy utilization.

[0004] In order to ensure the normal operation of the turbulent flow cooling and heat exchange equipment and improve the heat exchange efficiency, the design of the water quality filtration system is particularly important. Its core task is to efficiently remove particulate matter, suspended matter, sediments and possible harmful microorganisms in the cooling water. Although the existing filter materials, such as fiber filter elements, sand layers, etc., can effectively remove large particle impurities, they will become clogged, worn or fail during long-term use, resulting in frequent replacement and maintenance, thereby increasing operating costs, and traditional filtering equipment needs to be cleaned and maintained regularly during operation, otherwise the filtering effect will gradually decrease. The cleaning process may require downtime, affecting the normal operation of the equipment and increasing additional labor and time costs, so the present invention solves the shortcomings of the above technical problems. Summary of the invention

[0005] Based on the above-mentioned existing technical problems, the present invention proposes a device and method for filtering water quality of a disturbed flow cooling heat exchange equipment.

[0007] The primary filtering mechanism performs primary filtering on the spray water entering the heat exchange device to remove larger impurities in the water and removes the impurities regularly.

[0008] The aggregation mechanism aggregates fine impurities in the filtered spray water to form large particles, which are then filtered by the backwash filter.

[0009] Wherein, the sterilization mechanism sterilizes the water and removes bacteria in the water.

[0011] Through the above technical solution, in the heat exchange equipment, the cleanliness of the water directly affects the efficiency and service life of the equipment. However, since the water contains a large amount of impurities and particles, it may cause scaling, corrosion, clogging and other problems on the surface of the heat exchanger, thereby affecting the heat exchange efficiency and equipment operation. In order to effectively remove large particles of impurities contained in the water, such as sand, leaves, etc., the spray water discharged from the spray system enters the filter cage through the water inlet pipe, and the large particles of impurities are filtered through the filter holes. In order to discharge the impurities later, there is a distance between the position of the filter hole and the inner top wall of the filter hole, thereby realizing the upward transportation and discharge of impurities.

[0013] Through the above technical solution, in order to facilitate the rapid circulation of filtered spray water, a movable gap exists 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 circulation pipe along the guide groove for the next step of treatment.

[0014] Preferably, the primary filtering mechanism also includes a debris removal pipe fixedly connected to the upper surface of the conical cage, the outer surface of the debris removal pipe is rotatably connected to a driving pipe with driving teeth through a bearing, the upper surface of the driving pipe is penetrated by a debris removal hole, the inner side wall of the driving pipe is fixedly connected to a support ring plate, the upper surface of the support ring plate and the inner top surface of the driving pipe are slidably connected to sealing plates distributed in a ring array through the cooperation of guide columns and guide grooves.

[0015] Through the above technical scheme, the accumulation of large-particle impurities such as leaves and sand and gravel will affect the filtering effect of the conical cage. In order to regularly discharge the impurities in the conical cage, after the water level in the primary filter tank is lower than the lower surface of the conical cage, the impurity discharge hole is controlled to be exposed, so that the impurities can be discharged from the impurity discharge hole. In order to open the impurity discharge hole, the driving pipe drives the sealing plate on the supporting ring plate to rotate when rotating, and then the opening size of the impurity discharge hole can be adjusted.

[0016] Preferably, the inner bottom wall of the primary filter tank is fixedly connected to a waterproof motor through a waterproof shell, the inner bottom wall of the conical cage is rotatably connected to a conical screw conveying rod through a bearing, the outer surface of the output shaft of the waterproof motor is fixedly connected to the lower surface of the conical screw conveying rod through a coupling, the outer surface of the conical screw conveying rod is slidingly connected to the inner wall of the conical cage and the inner wall of the lower end of the impurity discharge pipe respectively, the outer surface of the primary filter tank is rotatably connected to a driving screw through a support platform, the driving screw is meshed with the driving teeth, and a side surface of the support platform is fixedly connected to a driving motor, and the outer surface of the output shaft of the driving motor is fixedly connected to the outer surface of the driving screw through a coupling.

[0017] Through the above technical scheme, in order to discharge the impurities in the conical cage, the waterproof motor drives the conical spiral conveying rod to rotate, and the outer surface of the conical spiral conveying rod fits the inner wall of the conical cage and the inner wall of the impurity discharge pipe, so that the impurities are transported upward and discharged to the outside of the primary filter tank through the impurity discharge hole. In order to control the rotation of the sealing plate, the driving motor drives the driving screw to rotate, so that it controls the rotation of the driving tube with driving teeth, so that the sealing plate can be linked, and the opening and closing control of the impurity discharge hole can be realized.

[0018] Preferably, the gathering mechanism includes a spoiler tube fixedly connected to the lower surface of the flow tube, the outer surface of the spoiler tube is fixedly connected to the lower surface of the primary filter tank through a connecting rod, the inner wall of the spoiler tube is rotatably connected to a movable shaft through a bearing, one side surface of the spoiler tube is fixedly connected to a rotating motor, the outer surface of the output shaft of the rotating motor is fixedly connected to the surface of the movable shaft, the outer surface of the movable shaft is fixedly sleeved with rolling discs distributed in a linear array, and the multiple rolling discs are eccentrically sleeved to the movable shaft.

[0019] Through the above technical scheme, the spray water preliminarily filtered by the conical cage flows from the circulation pipe to the spoiler pipe. In order to gather fine particles in the spray water and facilitate subsequent precision filtration, when the spray water flows in the spoiler pipe, the rotating motor drives the movable shaft to rotate, so that it drives the rolling disk to rotate, and the multiple rolling disks are staggered and eccentrically distributed, so that the water flow produces turbulence when the rolling disk rotates, thereby enhancing the aggregation effect of tiny particles in the water. At the same time, when the rolling disk contacts the inner wall of the spoiler pipe, the particles can be crushed to form larger agglomerates or sediments of suspended matter, which is beneficial to subsequent precision filtration.

[0020] Preferably, the gathering mechanism also includes a metal bellows arranged below the spoiler tube, both end surfaces of the metal bellows are fixedly connected with a stabilizing tube, one side surface of the stabilizing tube at one end is fixedly connected with a liquid inlet pipe, the upper surface of the liquid inlet pipe is fixedly connected with the lower surface of the spoiler tube, and the surface of the stabilizing tube at the other end is fixedly connected with the water inlet end of the backwash filter, a booster pump is installed on the outer surface of the liquid inlet pipe, the outer surface of the spoiler tube is fixedly connected with a suspension beam through a bracket, and two groups of reset ropes distributed in a linear array are fixedly connected to the upper surface of the metal bellows, and the two groups of reset ropes are relatively distributed and fixedly connected to the outer surface of the suspension beam.

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

[0022] Preferably, the sterilization mechanism includes a sterilization pipe arranged on one side of the backwash filter, and both side surfaces of the sterilization pipe are fixedly connected to heat sinks, and the upper surfaces of both ends of the sterilization pipe are fixedly connected to water flow pipes with valves, and one side of the water flow pipe is fixedly connected to a three-way pipe, and one end of one of the three-way pipes is fixedly connected to the output end of the backwash filter.

[0023] Through the above technical scheme, the spray water is further finely filtered through the backwash filter to remove tiny particles, harmful substances, oil stains, etc. in the water, ensuring that the water quality reaches high standards. In order to ensure that the cooling system does not have problems such as blockage and corrosion due to the growth of microorganisms, the spray water filtered by the backwash filter enters the sterilization pipe through the three-way pipe and the water flow pipe on one side. The sterilization pipe is equipped with UV ultraviolet sterilization lamps, which sterilize the water quality through ultraviolet rays to remove bacteria, algae and other microorganisms in the water, and the service life of the sterilization pipe is increased through the heat sink. Then the disinfected spray water is circulated through the water flow pipe and the three-way pipe on the other side.

[0024] Preferably, one end of the other three-way pipe 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 spoiler pipe are fixedly connected to a sewage pipe.

[0025] Through the above technical scheme, in order to regularly clean the filter unit and maintain the efficient operation of the filter, the automatic backwashing device is started 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 water flow direction of the backwash filter is reversed, flowing from the outlet to the inlet of the filter to wash away the dirt accumulated on the filter medium, and in the backwashing stage, the disinfected spray water flows in reverse from the circulation pipe to the backwash filter, metal bellows, spoiler pipe, and primary filter tank, thereby completing the backwashing, and the sewage is discharged from the corresponding sewage pipe.

[0026] The present invention provides a filtering method for filtering water quality of a turbulent flow cooling heat exchange equipment, comprising the following steps:

[0027] S1. The spray water discharged from the spray system enters the filter cage through the water inlet pipe, and the large particles of impurities are filtered through the filter holes. The spray water after preliminary filtration flows from the flow pipe to the spoiler pipe along the guide groove;

[0028] S2. When the spray water flows in the spoiler tube, the rotating motor drives the movable shaft to rotate, so that the rolling disc drives the rolling disc to rotate. The 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 tiny particles in the water. At the same time, when the rolling disc contacts the inner wall of the spoiler tube, the particles can be crushed, so that the suspended matter forms larger agglomerates or sediments;

[0029] S3, at this time, the spray water with turbulent flow treatment flows into the metal bellows from the liquid inlet pipe, and the spray water entering the metal bellows is pressurized by the booster pump, so that the instantaneous high-pressure water flow impacts the metal bellows to generate longitudinal waves and compress, thereby compressing the tiny particles into a ball, and the reset rope is made of steel wire rope and hangs the metal bellows, so that the two relative reset ropes can reset the deformed metal bellows in time, so that it pushes the spray water and the particles in the water forward to flow into the backwash filter, so that the water flow passes through the filter medium to filter out the solid particles and suspended matter in the water;

[0030] S4. The spray water is further finely filtered through the backwash filter to remove tiny particles, harmful substances, and oil stains in the water. The filtered spray water enters the sterilization pipe through the tee pipe and the water flow pipe on one side. The water quality is sterilized by the UV ultraviolet sterilization lamp in the sterilization pipe to remove bacteria and algae microorganisms in the water. Then the disinfected spray water is circulated through the water flow pipe and the tee pipe on the other side.

[0031] S5. When the water flow resistance in the backwash filter increases, indicating 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 is reversed, flowing from the outlet of the filter to the inlet direction, washing away the dirt accumulated on the filter medium, and in the backwash stage, the disinfected spray water flows in reverse from the circulation pipe to the backwash filter, the metal bellows, the spoiler pipe, and the primary filter tank, thereby completing the backwash, and the sewage is discharged from the corresponding sewage 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 driving motor drives the driving screw to rotate, so that it controls the driving tube with driving teeth to rotate. When the driving tube rotates, it drives the sealing plate on the supporting ring plate to rotate, thereby exposing the opening of the impurity discharge hole. Then the waterproof motor drives the conical spiral conveying rod to rotate, and the outer surface of the conical spiral conveying rod fits the inner wall of the conical cage and the inner wall of the impurity discharge tube, thereby conveying the impurities upward and discharging them to the outside of the primary filter tank through the impurity discharge hole, thereby increasing the service life of the conical cage.

[0033] The beneficial effects of the present invention are:

[0034] 1. By setting up a primary filtering mechanism, the spray water entering the heat exchange equipment is primarily filtered to remove larger impurities in the water, and the impurities are regularly removed. During the adjustment process, the spray water discharged from the spray system enters the filter cage through the water inlet pipe, and the large particles of impurities are filtered through the filter holes. In the backwashing stage, the driving motor drives the driving screw to rotate, so that it controls the driving tube with driving teeth to rotate. When the driving tube rotates, it drives the sealing plate on the supporting ring plate to rotate, thereby exposing the opening of the impurity discharge hole, and then the waterproof motor drives the conical spiral conveying rod to rotate, and the outer surface of the conical spiral conveying rod fits the inner wall of the conical cage and the inner wall of the impurity discharge pipe, so as to transport the impurities upward and discharge them to the outside of the primary filter tank through the impurity discharge hole, thereby increasing the service life of the conical cage.

[0035] 2. By setting up a gathering mechanism, the fine particles in the spray water can be gathered into agglomerates, so that they can be precisely filtered. During the adjustment process, the spray water entering the metal bellows is pressurized by the booster pump, so that the instantaneous high-pressure water flow impacts the metal bellows to generate longitudinal waves and compress them, thereby compressing the tiny particles into agglomerates. The reset rope is made of steel wire rope and the metal bellows is suspended, so that the two relative sets of reset ropes can reset the deformed metal bellows in time, so that it pushes the spray water and particles in the water forward and flows into the backwash filter, so that the water flows through the filter medium to filter out the 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 be blocked, corroded, and other problems occur due to the growth of microorganisms. During the adjustment process, the spray water filtered by the backwash filter enters the sterilization pipe through the three-way pipe and the water flow pipe on one side. UV ultraviolet sterilization lamps are distributed in the sterilization pipe. The water quality is sterilized by ultraviolet rays to remove bacteria, algae and other microorganisms in the water, and the service life of the sterilization pipe is increased through the heat sink. Then the disinfected spray water is circulated through the water flow pipe and the three-way pipe on the other side, thereby ensuring the cleanliness and safety of the water quality.

DETAILED DESCRIPTION

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] Reference Figure 1-Figure 13A filtering device for filtering water quality of a disturbed wave flow cooling heat exchange equipment comprises a primary filter tank 1 with supporting feet, one side of the primary filter tank 1 is fixedly connected with a water inlet pipe 2, a primary filter mechanism 4 is arranged inside the primary filter tank 1, a backwash filter 3 is arranged below the primary filter tank 1, a gathering mechanism 6 is arranged between the primary filter tank 1 and the backwash filter 3, and a sterilization mechanism 7 is arranged at the output end of the backwash filter 3.

[0053] The primary filtering mechanism 4 performs primary filtering on the spray water entering the heat exchange device to remove larger impurities in the water and remove the impurities regularly.

[0054] In heat exchange equipment, the cleanliness of water directly affects the efficiency and service life of the equipment. However, since the water contains a large amount of impurities and particles, it may cause scaling, corrosion, clogging and other problems on the surface of the heat exchanger, thereby affecting the heat exchange efficiency and equipment operation. In order to effectively remove large particles of impurities contained in the water, such as sand, leaves, etc., the primary filtering mechanism 4 includes a conical cage 41 fixedly connected to the inner wall of the primary filter tank 1, and the output end of the water inlet pipe 2 extends to the upper end of the inner part of the conical cage 41. The outer surface of the conical cage 41 is distributed in a circular array and is penetrated by filter holes 42. The height of the filter holes 42 accounts for 4 / 5 of the height of the conical cage 41. The spray water discharged by the spray system enters the filter cage through the water inlet pipe 2, and the large particles of impurities are filtered through the filter holes 42. In order to discharge the impurities later, there is a distance between the position of the filter hole 42 and the inner top wall of the filter hole 42, thereby realizing the upward transportation and discharge of impurities.

[0055] In order to facilitate the rapid circulation 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 guide groove 43 in the shape of an oblique cone. The inner bottom wall of the guide groove 43 is fixedly connected with 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 the next step of processing.

[0056] The accumulation of large particles of impurities such as leaves and sand and gravel will affect the filtering effect of the conical cage 41. In order to regularly discharge the impurities in the conical cage 41, the primary filtering 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 driving pipe 46 with driving teeth through a bearing. The upper surface of the driving pipe 46 is penetrated by a discharge hole 47. After the water level in the primary filter tank 1 is lower than the lower surface of the conical cage 41, the discharge hole 47 is controlled to be exposed, so that 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 driving pipe 46. The upper surface of the support ring plate 48 and the inner top surface of the driving pipe 46 are slidably connected with a sealing plate 49 distributed in a ring array through the cooperation of a guide column and a guide groove. When the driving pipe 46 rotates, the sealing plate 49 on the support ring plate 48 is driven to rotate, and the opening size of the discharge hole 47 can be adjusted.

[0057] In order to discharge impurities in the conical cage 41, the inner bottom wall of the primary filter tank 1 is fixedly connected to a waterproof motor 50 through a waterproof housing, and the inner bottom wall of the conical cage 41 is rotatably connected to a conical screw conveying rod 51 through a bearing. The outer surface of the output shaft of the waterproof motor 50 is fixedly connected to the lower surface of the conical screw conveying rod 51 through a coupling, and the outer surface of the conical screw conveying rod 51 is slidably connected to the inner wall of the conical cage 41 and the inner wall of the lower end of the impurity discharge pipe 45, respectively. The outer surface of the primary filter tank 1 is rotatably connected to a driving screw 52 through a support platform, and the driving screw 52 is meshed with a driving tooth. The waterproof motor 50 drives the conical screw The conveying rod 51 rotates, and the outer surface of the conical spiral conveying rod 51 fits the inner wall of the conical cage 41 and the inner wall of the impurity discharge pipe 45, so that the impurities are conveyed upward and discharged 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 driving motor 53 is fixedly connected to the surface of one side of the support platform. The outer surface of the output shaft of the driving motor 53 is fixedly connected to the outer surface of the driving screw 52 through a coupling. The driving screw 52 is driven to rotate by the driving motor 53, so that it controls the driving tube 46 with driving teeth to rotate, so that the sealing plate 49 can be linked to realize the opening and closing control of the impurity discharge hole 47.

[0058] By setting up the primary filtering mechanism 4, the spray water entering the heat exchange equipment is primarily filtered to remove larger impurities in the water, and the impurities are regularly removed. During the adjustment process, the spray water discharged from the spray system enters the filter cage through the water inlet pipe 2, and the large particles of impurities are filtered through the filter hole 42. In the backwashing stage, the driving motor 53 drives the driving screw 52 to rotate, so that it controls the driving tube 46 with driving teeth to rotate. When the driving tube 46 rotates, it drives the sealing plate 49 on the supporting ring plate 48 to rotate, thereby exposing the opening of the impurity discharge hole 47. Then the waterproof motor 50 drives the conical spiral conveying rod 51 to rotate, and the outer surface of the conical spiral conveying rod 51 fits the inner wall of the conical cage 41 and the inner wall of the impurity discharge pipe 45, so as to transport the impurities upward and discharge them to the outside of the primary filter tank 1 through the impurity discharge hole 47, so as to increase the service life of the conical cage 41.

[0059] The gathering mechanism 6 gathers the fine impurities in the filtered spray water to form 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 spoiler pipe 61. In order to gather fine particles in the spray water and facilitate subsequent precision filtration, the gathering mechanism 6 includes a spoiler pipe 61 fixedly connected to the lower surface of the flow pipe 44. The outer surface of the spoiler pipe 61 is fixedly connected to the lower surface of the primary filter tank 1 through a connecting rod. The inner wall of the spoiler pipe 61 is rotatably connected to a movable shaft 62 through a bearing. A rotating motor 63 is fixedly connected to the surface of one side of the spoiler 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 sleeved with rolling discs 64 distributed in a linear array, and the multiple rolling discs 64 are eccentrically sleeved with the movable shaft 62. When the spray water flows in the spoiler tube 61, the rotating motor 63 drives the movable shaft 62 to rotate, so that it drives the rolling discs 64 to rotate. The multiple rolling discs 64 are staggered and eccentrically distributed, so that the water flow produces turbulence when the rolling discs 64 rotate, thereby enhancing the aggregation effect of tiny particles in the water. At the same time, when the rolling discs 64 contact the inner wall of the spoiler tube 61, the particles can be crushed to form larger agglomerates or sediments of the suspended matter, which is beneficial to the subsequent precision filtration.

[0061] In order to induce the water flow to form disturbances or vortices, so that the flow velocity and turbulence intensity of the water flow are significantly improved, so that the tiny particles in the water can collide and gather with each other more easily, thereby forming larger agglomerates or sediments, which are convenient for subsequent filtration and removal, the gathering mechanism 6 also includes a metal bellows 65 arranged below the spoiler tube 61, and the surfaces of both ends of the metal bellows 65 are fixedly connected to a stabilizing tube 66, and a side surface of the stabilizing tube 66 at one end is fixedly connected to a liquid inlet pipe 67, the upper surface of the liquid inlet pipe 67 is fixedly connected to the lower surface of the spoiler tube 61, and the surface of the stabilizing tube 66 at the other end is fixedly connected to the water inlet end of the backwash filter 3, and a booster pump 68 is installed on the outer surface of the liquid inlet pipe 67, and the outer surface of the spoiler tube 61 is fixedly connected to a suspension beam 69 through a bracket. The upper surface of the metal bellows 65 is fixedly connected to the water inlet end of the backwash filter 3. Two groups of reset ropes 691 distributed in a linear array are fixedly connected, and the two groups of reset ropes 691 are relatively distributed and fixedly connected to the outer surface of the suspension beam 69. The liquid in the spoiler tube 61 flows into the metal bellows 65 from the liquid inlet pipe 67, and the spray water entering the metal bellows 65 is pressurized by the booster pump 68, so that the instantaneous high-pressure water flow impacts the metal bellows 65 to generate longitudinal waves and compress it, thereby compressing the tiny particles into a ball. The reset ropes 691 are made of steel wire ropes and suspend the metal bellows 65, so that the two relative reset ropes 691 can reset the deformed metal bellows 65 in time, so that it pushes the spray water and the particles in the water forward and flows into the backwash filter 3, so that the water flow passes through the filter medium to filter out impurities such as solid particles and suspended matter in the water.

[0062] By setting up the gathering mechanism 6, the fine particles in the spray water can be gathered into agglomerates, so that they can be precisely filtered. During the adjustment process, the spray water entering the metal bellows 65 is pressurized by the booster pump 68, so that the instantaneous high-pressure water flow impacts the metal bellows 65 to generate longitudinal waves and compress it, thereby compressing the tiny particles into agglomerates. The reset rope 691 is made of steel wire rope and suspends the metal bellows 65, so that the two relative sets of reset ropes 691 can reset the deformed metal bellows 65 in time, so that it pushes the spray water and the particles in the water forward and flows into the backwash filter 3, so that the water flow passes through the filter medium to filter out the agglomerated solid particles and suspended matter in the water, thereby reducing the operating cost.

[0063] Among them, the sterilization mechanism 7 sterilizes the water and removes bacteria in the water.

[0064] The backwash filter 3 is used to further precisely filter the spray water to remove tiny particles, harmful substances, oil stains, etc. in the water to ensure that the water quality reaches high standards. In order to ensure that the cooling system does not cause blockage, corrosion, and other problems due to the growth of microorganisms, the sterilization mechanism 7 includes a sterilization pipe 71 arranged on one side of the backwash filter 3. The surfaces of both sides of the sterilization pipe 71 are fixedly connected with heat sinks 72. The upper surfaces of both ends of the sterilization pipe 71 are fixedly connected with water flow pipes 73 with valves. One side of the water flow pipe 73 is fixedly connected with a three-way pipe 74, one end of which 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 sterilization lamps are distributed in the sterilization pipe 71. The water quality is sterilized by ultraviolet rays to remove bacteria, algae and other microorganisms in the water, and the service life of the sterilization pipe 71 is increased through the heat sink 72. Then the disinfected spray water passes through the water flow pipe 73 and the three-way pipe 74 on the other side to complete the circulation of the spray water.

[0065] In order to regularly clean the filter unit and maintain efficient operation of the filter, one end of the other three-way pipe 74 is fixedly connected to a circulation pipe 75, and 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 spoiler pipe 61 are fixedly connected to a drain pipe 76. According to the set time interval or water quality monitoring feedback, the automatic backwashing device is started to clean the filter unit to 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 outlet of the filter to the inlet direction to wash away the dirt accumulated on the filter medium, and in the backwashing stage, the disinfected spray water flows in reverse from the circulation pipe 75 to the backwash filter 3, the metal bellows 65, the spoiler pipe 61, and the primary filter tank 1, thereby completing the backwashing, and 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 be blocked, corroded, and other problems occur 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. UV ultraviolet sterilization lamps are distributed in the sterilization pipe 71. The water quality is sterilized by ultraviolet rays to remove bacteria, algae and other microorganisms in the water. The service life of the sterilization pipe 71 is increased through the heat sink 72. Then the disinfected spray water is circulated 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 Figure 1-Figure 13 , a filtering method of a filtration device for filtering water quality of a disturbed wave flow cooling heat exchange equipment, comprising the following steps:

[0068] S1, the spray water discharged from the spray system enters the filter cage through the water inlet pipe 2, and the large particles of impurities are filtered through the filter hole 42. The spray water after preliminary filtration flows along the guide groove 43 from the flow pipe 44 to the spoiler pipe 61;

[0069] S2. When the spray water flows in the spoiler tube 61, the rotating motor 63 drives the movable shaft 62 to rotate, so that the rolling disc 64 is driven to rotate. The plurality of rolling discs 64 are staggered and eccentrically distributed, so that the water flow is turbulent when the rolling discs 64 rotate, thereby enhancing the aggregation effect of tiny particles in the water. At the same time, when the rolling discs 64 contact the inner wall of the spoiler tube 61, the particles can be crushed, so that the suspended matter forms larger agglomerates or sediments.

[0070] S3, at this time, the spray water with turbulent flow treatment flows into the metal bellows 65 from the liquid inlet pipe 67, and the spray water entering the metal bellows 65 is pressurized by the booster pump 68, so that the instantaneous high-pressure water flow impacts the metal bellows 65 to generate longitudinal waves and compress, thereby compressing the tiny particles into a ball, and the reset rope 691 is made of steel wire rope and suspends the metal bellows 65, so that the two relative reset ropes 691 can reset the deformed metal bellows 65 in time, so that it pushes the spray water and the particles in the water forward to flow into the backwash filter 3, so that the water flow passes through the filter medium to filter out the solid particles and suspended matter in the water;

[0071] S4, the spray water is further finely filtered by the backwash filter 3 to remove the tiny particles, harmful substances and oil in the water, and the filtered spray water enters the sterilization pipe 71 through the tee pipe 74 and the water flow pipe 73 on one side, and the water quality is sterilized by the UV ultraviolet sterilization lamp in the sterilization pipe 71 to remove bacteria and algae microorganisms in the water, and then the disinfected spray water is circulated through the water flow pipe 73 and the tee pipe 74 on the other side;

[0072] S5. When the water flow resistance in the backwash filter 3 increases, indicating 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 direction, washing away the dirt accumulated on the filter medium, and in the backwash stage, the disinfected spray water flows in the reverse direction from the circulation pipe 75 to the backwash filter 3, the metal bellows 65, the spoiler pipe 61, and the primary filter tank 1, thereby completing the backwash, and the sewage is discharged from the corresponding sewage 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 driving motor 53 drives the driving screw 52 to rotate, so that it controls the driving tube 46 with driving teeth to rotate. When the driving tube 46 rotates, it drives the sealing plate 49 on the supporting ring plate 48 to rotate, thereby exposing the opening of the impurity discharge hole 47. Then the waterproof motor 50 drives the conical spiral conveying rod 51 to rotate, and the outer surface of the conical spiral conveying rod 51 fits the inner wall of the conical cage 41 and the inner wall of the impurity discharge pipe 45, so as to transport the impurities upward and discharge them to the outside of the primary filter tank 1 through the impurity discharge hole 47, thereby increasing the service life of the conical cage 41.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
