Description

Technical Field

[0001] This invention relates to the field of cooling tower technology, and more particularly to a cooling tower with a waste heat utilization structure. Background Technology

[0002] A cooling tower is a tower-shaped heat dissipation device that cools water. It cools the working fluid by allowing the cooling water to come into full, direct or indirect contact with the atmosphere inside the tower, utilizing methods such as evaporation. The main heat dissipation methods of a cooling tower are conduction and evaporation; radiation heat dissipation is negligible due to its small volume. Conduction refers to the transfer of heat from the high-temperature water to the low-temperature air through the contact between water and air; evaporation involves the diffusion of water molecules into the air, thus lowering the water temperature.

[0003] When a cooling tower cools a high-temperature liquid in a circulating system, it relies on the packing layer inside the tower to create a heat exchange environment where the gas and liquid are in full contact. Outside air continuously enters the tower through the air inlet and exchanges heat with the sprayed high-temperature liquid. However, because this cooling process is an open gas-liquid contact mode, impurities such as dust, silt, suspended particulate matter, and microbial spores contained in the outside air will enter the tower with the airflow and mix into the cooled liquid. After these impurities re-enter the circulating system with the liquid, they will gradually accumulate on the inner walls of the pipes, the heat exchange surfaces of the heat exchangers, and the equipment cavities. Long-term operation will not only cause the inner diameter of the pipes to shrink and the heat exchange efficiency of the heat exchangers to decrease, but it will also easily cause malfunctions such as pipe blockage and valve sticking. In severe cases, it may even lead to insufficient flow in the circulating system and local overheating shutdown of equipment, thus threatening the stability and safety of the entire production or operation system.

[0004] Therefore, a new cooling tower with a waste heat utilization structure needs to be designed to solve the above problems. Summary of the Invention

A water supply pipe communicating with the plurality of rinsing nozzles is provided on the outer wall of the shaft, and the bottom end of the water supply pipe passes through the bottom surface of the semi-filter cartridge and is fixedly connected to the through-hole. A circulation pump is fixedly installed on the bottom surface of the filter, and a conduit is fixedly installed at the inlet end of the circulation pump.

[0010] As a preferred embodiment of the present invention, a connecting component is provided between the first connecting port and the second connecting port, and between the liquid outlet of the circulating pump and the bottom end of the conduit.

[0011] As a preferred embodiment of the present invention, the communication component includes a fixed sleeve fixedly installed on the inner top surface of the filter and communicating with the communication port one.

[0012] As a preferred embodiment of the present invention, a wedge block is fixedly installed on the bottom surface of the sealing ring, and a wedge block groove corresponding to the wedge block is opened on the top surface of the semi-filter cartridge.

[0013] As a preferred embodiment of the present invention, an upper cover plate corresponding to the connecting component is fixedly installed on the side of the fixing plate, a sealing plate corresponding to the second connecting port is fixedly installed on the side of the fixing plate away from the upper cover plate, a lower cover plate for sealing the space between the bottom surface of the semi-filter cartridge and the inner bottom surface of the filter is fixedly installed on the bottom side of the fixing plate, and a sealing plate corresponding to the bottom end of the water supply pipe is fixedly installed on the inner wall of the lower cover plate.

[0014] As a preferred embodiment of the present invention, the filtrate assembly includes a base fixedly installed on the bottom surface of the filter away from the lower baffle. A rinsing baffle located outside the semi-filter cartridge is fixedly installed on the top surface of the base.

[0015] As a preferred embodiment of the present invention, the top end of the conduit is connected to the liquid storage chamber, and a filter screen is provided on the inner wall of the connection between the liquid storage chamber and the conduit.

[0016] The present invention has the following beneficial effects: 1. In this invention, the non-stop switching structure of the dual-chamber dual-half filter cartridge, combined with the drive motor driving the rotating plate to rotate 180° to realize the interchange of filter cartridge positions, allows the working chamber to continuously filter while the empty chamber can simultaneously complete the filter cartridge flushing without stopping the machine for maintenance. This ensures the continuity of circulating water filtration, avoids the interruption of cooling tower system operation due to shutdown, and prevents pipeline blockage by intercepting impurities, thereby improving the overall system's operational stability and efficiency. 2. In this invention, a reciprocating swing-type high-pressure flushing assembly is adopted. The water flow impacts the baffle, which drives the rotating ring and nozzle to rotate and compress the torsion spring. The nozzle reciprocates by means of the torsion spring's restoring force. This allows for all-round, dead-angle-free flushing of the inner wall of the semi-filter cartridge. At the same time, the flushing wastewater is guided by the baffle, collected in the liquid storage chamber, and recycled after secondary filtration by the filter screen. This ensures the cleaning effect of the filter cartridge and the subsequent filtration performance, while reducing water consumption and achieving water conservation and emission reduction. 3. In this invention, through the sealing of the baffle plate, the on / off control of the sealing plate, and the linkage structure of the wedge block and spring, the upper and lower baffle plates ensure that the liquid only passes through the filter cartridge and filter screen during filtration. The sealing plate blocks liquid leakage when the filter cartridge is switched. The wedge block and spring assembly precisely controls the opening and closing of the connection port. The multiple sealing and on / off control structures work together to avoid problems such as the mixing of the filtrate and the rinsing liquid and liquid loss, thus ensuring the cleanliness of the filtered water.

[0019] 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.

[0020] Example 1: A cooling tower with a waste heat utilization structure disclosed in this example, referring to... Figure 1-9 The system includes a tower body 11 and a water distributor 12 disposed inside the tower body 11. A packing layer 13 is disposed on the inner wall of the tower body 11 below the water distributor 12. A water collection tank 14 is disposed at the bottom of the tower body 11. A fan 15 is disposed at the top of the tower body 11. Four air inlets 16 are provided on the side of the tower body 11 between the packing layer 13 and the water collection tank 14. A heat exchange tube 17 is disposed inside the water collection tank 14. A filter 22 corresponding to the water collection tank 14 is disposed on the side of the tower body 11. A communication structure for communicating with the water collection tank 14 is provided on the filter 22. A rotating plate 33 is disposed inside the filter 22. Half filter cartridges 34 are fixedly installed on both sides of the rotating plate 33. A support structure corresponding to the rotating plate 33 is disposed inside the filter 22. A rinsing assembly for rinsing the half filter cartridge 34 is disposed on the bottom surface of the half filter cartridge 34. A filtrate assembly is disposed on one side of the bottom surface of the filter 22. The connecting structure includes an outlet pipe 21 that is fixedly installed on the side of the tower body 11 and connected to the water collection tank 14 and the filter 22. The top surface of the filter 22 is provided with a connecting port 24, and a drain pipe 23 that is fixedly installed on the top surface of the filter 22 and connected to the connecting port 24. The support structure includes a fixing plate 31 fixedly installed on the inner wall of the filter 22, an installation port 32 is provided on the side of the fixing plate 31, a rotating plate 33 is rotatably installed on the inner wall of the installation port 32 via a rotating shaft, a drive motor 35 is fixedly installed on the top surface of the filter 22, the output end of the drive motor 35 is fixedly connected to the top end of the rotating shaft, and a communication port 36 is provided on the top surface of the half filter cartridge 34.

[0021] The implementation principle of this embodiment is as follows: During use, the high-temperature circulating water to be cooled is pumped to the top of the tower 11 and evenly sprayed onto the packing layer 13 by the water distributor 12, forming fine water droplets or water film to increase the contact area with the air; at the same time, the outside cold air enters from the air inlet 16 at the bottom of the tower 11 under natural convection, passes through the packing layer 13 from bottom to top, and forms a countercurrent contact with the falling hot water. In this process, sensible heat exchange occurs on the one hand, that is, the hot water directly transfers heat to the low-temperature air, and on the other hand... Latent heat exchange occurs on the surface, where some of the hot water absorbs heat and evaporates into water vapor, which is carried away by the airflow. The cooled water, after heat exchange, falls into the water collection tank 14 at the bottom of the tower and is pumped back to the heat exchange equipment for recycling. The humid air that has absorbed heat and water vapor is discharged into the atmosphere after the water droplets are separated by the fan 15 and water separator at the top of the tower 11. The liquid in the water collection tank 14 has a certain temperature after heat exchange, so it can exchange heat with the cold water in the heat exchange tube 17 again, realizing the utilization of waste heat. When the circulating liquid that has been cooled in the water collection tank 14 is put back into use, it can first be transported to the inside of the special filter 22 through the outlet pipe 21. The liquid first flows into the space on one side of the filter 22 cavity that is connected to the fixed plate 31, and directly enters the semi-filter cartridge 34 structure on that side. Utilizing the retention characteristics of the filter screen pore size of the semi-filter cartridge 34, solid impurities such as mud, suspended solids, and biological slime mixed in the liquid are efficiently filtered onto the outer wall of the semi-filter cartridge 34. The clean liquid after filtration and purification then smoothly enters the inner chamber of the semi-filter cartridge 34, and is subsequently discharged through the connecting port 24 at the end of the semi-filter cartridge 34 and the drain pipe 23 of the filter 22, directly supplying subsequent production or heat exchange systems for recycling. Because the filter 22 adopts a symmetrical structure design with two chambers and two semi-filter cartridges 34, when the liquid continuously enters one side of the filter 22 cavity, the other side... The side chamber is in a closed, empty state. When impurities accumulate to a certain extent on the outside of the currently used semi-filter cartridge 34 and the filtration efficiency decreases, the drive motor 35 of the filter 22 can be started. The motor outputs power to drive the rotating shaft that runs through the chamber of the filter 22 and the rotating plate 33 fixed on the rotating shaft to rotate 180 degrees synchronously. During the rotation of the rotating plate 33 in the mounting port 32 of the filter 22, it can synchronously drive the two semi-filter cartridges 34 connected on both sides to complete the position exchange. At this time, the semi-filter cartridge 34 that has adsorbed a large amount of impurities is switched to an empty chamber where no liquid enters. High-pressure flushing and other maintenance operations can be performed in this side chamber. After cleaning, the semi-filter cartridge 34 can be switched to the working chamber for use at any time by rotating the rotating plate 33 again. This enables the filter 22 to operate continuously without stopping, ensuring the cleanliness of the circulating liquid and the stability of the system operation.

[0022] Example 2: Based on Example 1, this example discloses a cooling tower with a waste heat utilization structure, such as... Figure 3 , Figure 7 and Figure 8 As shown, the rinsing assembly includes a shaft 41 fixedly installed on the bottom surface of the semi-filter cartridge 34. Several rotating rings 42 arranged in a linear array are rotatably mounted on the outer wall of the shaft 41. A rinsing nozzle 43 is fixedly installed on the outer wall of the rotating rings 42. Several torsion springs 44 are mounted on the outer wall of the shaft 41, and the two ends of the torsion springs 44 are fixedly connected to the rotating rings 42 and the shaft 41, respectively. Several brackets 45 corresponding to the positions of the rotating rings 42 are fixedly installed on the outer wall of the shaft 41. A baffle 46 is fixedly installed at the bottom end of the bracket 45. A water supply pipe 47 communicating with several rinsing nozzles 43 is provided on the outer wall of the shaft 41, and the bottom end of the water supply pipe 47 passes through the bottom surface of the semi-filter cartridge 34 and is fixedly connected to the through-hole. A circulation pump 48 is fixedly installed on the bottom surface of the filter 22, and a conduit 49 is fixedly installed at the inlet end of the circulation pump 48.

[0023] The implementation principle of this embodiment is as follows: When the filter cartridge 34, which has adsorbed a large amount of impurities, rotates with the rotating plate 33 to switch to the empty chamber of the filter 22, the water supply pipe 47 matching the chamber is immediately connected to the circulation pump 48. After the circulation pump 48 starts, it draws water through the conduit 49 and delivers it to the flushing assembly. The flushing assembly is equipped with several flushing nozzles 43 arranged in two groups in a cross-symmetrical layout. After the high-pressure water jet is sprayed from the flushing nozzle 43, it first impacts the baffle 46 preset at the bottom of the bracket 45. Under the blocking reaction force of the baffle 46, the water pressure drives the flushing nozzle 43 and the rotating ring connected to it. 42 rotates along shaft 41, simultaneously compressing the torsion spring 44 mounted on shaft 41. After the torsion spring 44 is compressed to its limit position, the elastic restoring force of the torsion spring 44 drives the rotating ring 42 and the flushing nozzle 43 to rotate back to their initial positions in the opposite direction. This reciprocating motion allows the flushing nozzle 43 to perform all-round, no-dead-angle high-pressure flushing of the inner wall of the semi-filter cartridge 34 in the empty chamber in a swinging manner, thoroughly washing away the residual impurities attached to the inner wall of the filter cartridge, effectively ensuring the cleanliness of the semi-filter cartridge 34 and its subsequent filtration performance, and ensuring that it can stably perform its filtration function when it is switched back to the working chamber.

[0024] Example 3: Based on Example 1, this example discloses a cooling tower with a waste heat utilization structure, such as... Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, connecting components are provided between connecting port 24 and connecting port 36, and between the outlet of the circulating pump 48 and the bottom of the conduit 49. Each connecting component includes a fixed sleeve 51 fixedly installed on the top surface of the filter 22, communicating with connecting port 24. A sliding sleeve 52 is slidably installed on the outer wall of the fixed sleeve 51. A spring 54 is fitted onto the outer wall of the fixed sleeve 51, with both ends of the spring 54 fixedly connected to the fixed sleeve 51 and the sliding sleeve 52, respectively. A sealing ring 53 is fixedly installed at the end of the sliding sleeve 52, and a connector for connecting port 36 is fixedly installed at the end of the sealing ring 53. The sealing ring 55 and the sealing pressure ring 53 are fixedly installed with a wedge 56 on the bottom surface. The top surface of the semi-filter cartridge 34 is provided with a wedge groove 57 corresponding to the wedge 56. The side of the fixing plate 31 is fixedly installed with an upper cover plate 61 corresponding to the connecting component. The side of the fixing plate 31 away from the upper cover plate 61 is fixedly installed with a sealing plate 62 corresponding to the connecting port 36. The bottom side of the fixing plate 31 is fixedly installed with a lower cover plate 63 for sealing the bottom surface of the semi-filter cartridge 34 and the inner bottom surface of the filter 22. The inner wall of the lower cover plate 63 is fixedly installed with a sealing plate 64 corresponding to the bottom end of the water supply pipe 47.

[0025] The implementation principle of this embodiment is as follows: When the semi-filter cartridge 34 in the working chamber of the filter 22 is in the filtration operation state, its top and bottom ends are tightly sealed by the matching upper cover plate 61 and lower cover plate 63, respectively. This effectively prevents the liquid to be filtered from seeping into the upper and lower end faces of the semi-filter cartridge 34, ensuring that the liquid can only pass through the filter screen from the outside of the semi-filter cartridge 34 to enter the inside, thus ensuring the stability of the filtration process and the impurity interception effect. During the position change of the two semi-filter cartridges 34 as the rotating plate 33 rotates, the preset sealing plate one 62 and sealing plate two 64 will simultaneously automatically seal the connection port one 24 of the drain pipe 23 and the port of the water supply pipe 47, preventing leakage or mixing of the liquid to be filtered in the working chamber and the flushing wastewater in the empty chamber, thus preventing liquid loss. The on / off control principle of the connection port one 24 and the connection port two 36 on the semi-filter cartridge 34 is completely consistent with the connection control principle of the circulating pump 48 and the water supply pipe 47. Here, the connection port one 24 and the connection port two 36 on the semi-filter cartridge 34 are used as the connection control principle. Taking the connection process between port 24 and port 36 as an example, when the rotating plate 33 drives the semi-filter cartridge 34 to rotate and switch positions, the pre-set wedge groove 57 on the rotating plate 33 will simultaneously squeeze and push the wedge 56, causing the sliding sleeve 52 to slide along the axial direction of the fixed sleeve 51 and compress the built-in spring 54. This causes the sealing ring 55 at the end of the sliding sleeve 52 to disengage from the sealing surface of port 36, so that port 24 and port 36 are disconnected. After the rotating plate 33 rotates to the position and the semi-filter cartridge 34 on the other side is accurately switched to the designated position in the working chamber, the compressed spring 54 will release the elastic restoring force, push the sliding sleeve 52 to slide in the opposite direction, and drive the wedge 56 to re-embed into the corresponding wedge groove 57. At the same time, the sealing ring 55 will once again tightly fit the sealing surface of port 36, thereby achieving stable connection between the drain pipe 23 and the inside of the semi-filter cartridge 34 in the working state, ensuring that the filtered clean liquid can be discharged smoothly.

[0026] Example 4: Based on Example 1, this example discloses a cooling tower with a waste heat utilization structure, such as... Figure 5 and Figure 9 As shown, the filtrate assembly includes a base 71 fixedly installed on the bottom surface of the filter 22 away from the lower baffle 63. A rinsing baffle 72 located outside the semi-filter cartridge 34 is fixedly installed on the top surface of the base 71. A clearance opening 73 corresponding to the connecting assembly is opened on the bottom surface of the base 71. A discharge port 74 located between the semi-filter cartridge 34 and the rinsing baffle 72 is opened on the top surface of the base 71. A liquid storage chamber 75 communicating with the discharge port 74 is opened inside the base 71. The top end of the conduit 49 communicates with the liquid storage chamber 75, and a filter screen 76 is provided on the inner wall of the connection between the liquid storage chamber 75 and the conduit 49.

[0027] The implementation principle of this embodiment is as follows: When the flushing nozzle 43 performs high-pressure flushing on the semi-filter cartridge 34 switched to the empty chamber, the flushing liquid carrying impurities is sprayed through the nozzle onto the inner wall of the semi-filter cartridge 34. Under the impact force, the mud, sand, suspended matter and other impurities trapped on the outside of the filter cartridge are washed away. Then, the flushing liquid carrying these impurities penetrates the filter screen of the semi-filter cartridge 34 and sprays out, directly hitting the side of the pre-set flushing baffle 72 inside the empty chamber. With the blocking effect of the baffle, the flow direction is changed, and it flows smoothly downward along the baffle wall, finally collecting at the bottom of the chamber and flowing into the specially set liquid storage chamber through the discharge port 74. The flushing fluid is temporarily stored in the storage chamber 75. To achieve the recycling of flushing water resources, the circulation pump 48 can extract the flushing fluid collected in the storage chamber 75 through the conduit 49 and deliver it to the flushing nozzle 43 as a flushing water source. At the same time, during the extraction process, a special filter screen 76 is installed at the connection between the storage chamber 75 and the conduit 49, which can perform secondary filtration on the return flushing fluid in the storage chamber 75, effectively intercepting solid impurities carried in the flushing fluid, and preventing impurities from entering the circulation pump 48 and the flushing nozzle 43 with the return fluid, causing blockage or wear. This ensures the cleanliness of the circulating flushing fluid and the stability and efficiency of the flushing operation.

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.
