Description

Technical Field

[0001] This application relates to the technical field of heat exchanger descaling equipment, and in particular to a scale prevention and scale removal device. Background Technology

[0002] A cooling tower heat exchanger is a heat exchange device used to cool circulating water. It is mainly used in the industrial field. By transferring the heat of high-temperature circulating water to the air, it cools the water and ensures the normal operation of process equipment. Its core function is to reduce the temperature of circulating water and maintain the thermal balance of the system by utilizing the principles of water evaporation and heat conduction.

[0003] Currently, during the use of cooling tower heat exchangers, as the working time increases, a large amount of scale easily accumulates on the inner wall of the heat exchanger pipes, causing pipe blockage and making it difficult to remove the scale, resulting in a decrease in the working efficiency of the heat exchanger. Utility Model Content

[0004] Therefore, it is necessary to provide a device for preventing and removing scale from cooling tower heat exchangers.

[0005] A scale prevention and scale removal device is used in a cooling tower heat exchanger. The device includes a main pipe, a driving component, and a spiral assembly. The spiral assembly is sleeved on the outer periphery of the main pipe. A peeling component is provided on the spiral assembly. One end of the peeling component is connected to the spiral assembly, and the other end extends away from the spiral assembly and is used to abut against the inner wall of the cooling tower heat exchanger. The outer periphery of the spiral assembly has a guide groove that extends spirally around the axis of the spiral assembly. The driving component is connected to the main pipe and can drive the spiral assembly to vibrate through the main pipe, so that the end of the peeling component away from the spiral assembly rubs against the inner wall of the cooling tower heat exchanger.

[0006] In one embodiment, the spiral assembly includes a sleeve and a spiral disk. The sleeve is fitted around the outer periphery of the main pipe, a peeling member is connected to the outer wall of the sleeve, and the spiral disk is fixedly fitted around the outer periphery of the sleeve and extends axially around the sleeve, so that a guide groove is formed between the side wall of the spiral disk and the outer wall of the main pipe; or, the spiral assembly includes a sleeve fitted around the outer periphery of the main pipe, a peeling member is connected to the outer wall of the sleeve, and a guide groove is formed on the outer wall of the sleeve.

[0007] In one embodiment, the stripping member includes a cantilever and a friction block. One end of the cantilever is connected to a spiral assembly, and the other end extends radially along the spiral assembly. The friction block is connected to the end of the cantilever away from the spiral assembly, and the friction block has an arcuate surface for contacting the inner wall of the cooling tower heat exchanger. In one embodiment, the spiral assembly further includes a descaling plate, which is fixedly connected to the cantilever. One end of the descaling plate protrudes from the arcuate surface, and this protruding end includes multiple protrusions.

[0008] In one embodiment, the anti-scaling and scale removal device further includes a fixed sleeve and a retaining ring, wherein the fixed sleeve is fixedly disposed on the outer periphery of the main pipe and the retaining ring is fixedly connected to the fixed sleeve.

[0009] The spiral assembly has an assembly groove at its axial end. The assembly groove has an inner sidewall and an outer sidewall that are arranged radially opposite to each other. The retaining ring is installed in the assembly groove, and the outer ring of the retaining ring abuts against the outer sidewall. The inner ring of the retaining ring is in clearance fit with the inner sidewall. Furthermore, as the driving component drives the main pipe to vibrate, the spiral assembly can rotate or swing around the main pipe with the abutting point of the outer ring of the retaining ring against the outer sidewall as the fulcrum.

[0010] In one embodiment, the anti-scaling and scale removal device further includes a limiting plate sandwiched between the outer ring of the retaining ring and the outer side wall.

[0011] In one embodiment, the cooling tower heat exchanger has two mounting ports, and the anti-scaling and scale removal device further includes a first mounting component and a second mounting component. The first mounting component is fixedly connected to one end of the main pipe and is used to be installed to one of the mounting ports; the second mounting component is fixedly connected to the other end of the main pipe and is used to be installed to the other mounting port.

[0012] In one embodiment, the first mounting assembly includes a first mounting cylinder, a first connector, and a first mounting flange. The first connector is located inside the first mounting cylinder and is fixedly connected to the inner wall of the first mounting cylinder. The first mounting flange is located at the axial end of the first mounting cylinder and is used to connect to a mounting port.

[0013] In one embodiment, the drive includes a plurality of vibration motors, which are respectively mounted on the outer wall of the first mounting cylinder.

[0014] In one embodiment, the second mounting assembly includes a second mounting cylinder, a second connector, and a second mounting flange. The second connector is located inside the second mounting cylinder and is fixedly connected to the inner wall of the second mounting cylinder. The second mounting flange is located at the axial end of the second mounting cylinder and is used to connect to a mounting port.

[0015] Compared with existing technologies, the anti-scaling and scale removal device provided in this application, by setting a guide channel in the spiral assembly, guides the fluid to form a spiral flow within the cooling tower heat exchanger, increasing the turbulence of the fluid and making it difficult for impurities in the fluid to adhere to the inner wall of the cooling tower heat exchanger, thereby effectively preventing scale formation and reducing the probability of scale formation at the source. Furthermore, when the driving component drives the spiral assembly to vibrate, the peeling component continuously rubs against the inner wall of the cooling tower heat exchanger, mechanically breaking down and peeling off the existing scale. Thus, it not only prevents scale formation in the cooling tower heat exchanger but also removes it, thereby helping to ensure the working efficiency of the cooling tower heat exchanger.

[0029] Please see Figure 1 and Figure 2 This application provides an anti-scaling and scale removal device 100 for use in a cooling tower heat exchanger. The anti-scaling and scale removal device 100 includes a main pipe 10, a driving member 20, and a spiral assembly 30. The spiral assembly 30 is sleeved on the outer periphery of the main pipe 10. A peeling member 33 is provided on the spiral assembly 30. One end of the peeling member 33 is connected to the spiral assembly, and the other end extends away from the spiral assembly 30 and is used to abut against the inner wall of the cooling tower heat exchanger. The outer periphery of the spiral assembly 30 has a guide groove 321, which extends spirally around the axis of the spiral assembly. The driving member 20 is connected to the main pipe 10, and the driving member 20 can drive the spiral assembly 30 to vibrate through the main pipe 10, so that the end of the peeling member 33 away from the spiral assembly 30 rubs against the inner wall of the cooling tower heat exchanger.

[0030] Understandably, by setting the guide channel 321 in the spiral assembly 30, the guide channel 321 can guide the fluid to form a spiral flow within the cooling tower heat exchanger, increasing the turbulence of the fluid and making it difficult for impurities in the fluid to adhere to the inner wall of the cooling tower heat exchanger, thereby effectively preventing the formation of scale and reducing the probability of scale formation from the source. Furthermore, when the driving component 20 drives the spiral assembly 30 to vibrate, the peeling component 33 continuously rubs against the inner wall of the cooling tower heat exchanger, which can mechanically break down and peel off the existing scale. Thus, not only can scale prevention be achieved in the cooling tower heat exchanger, but also scale removal, thereby helping to ensure the working efficiency of the cooling tower heat exchanger.

[0031] In one embodiment, the number of spiral assemblies 30 is configured to be multiple, and the multiple spiral assemblies 30 are spaced apart along the extension direction of the main pipe 10. In this way, more uniform anti-scaling and descaling can be performed inside the cooling tower heat exchanger.

[0032] In one embodiment, the spiral assembly 30 includes a sleeve 31 and a spiral disk 32. The sleeve 31 is fitted around the outer periphery of the main pipe 10, and a peeling member 33 is fixedly connected to the outer wall of the sleeve 31. The spiral disk 32 is fixedly fitted around the outer periphery of the sleeve 31 and extends axially around the sleeve 31, so that a guide groove 321 is formed between the side wall of the spiral disk 32 and the outer wall of the main pipe 10. That is, in this embodiment, the sleeve 31 and the spiral disk 32 are separately disposed, processed separately and then fixedly connected.

[0033] In another embodiment, the spiral assembly 30 includes a sleeve 31, which is fitted around the outer periphery of the main tube 10. A peeling member 33 is fixedly connected to the outer wall of the sleeve 31, and a flow guide groove 321 is formed on the outer wall of the sleeve 31. That is, in this embodiment, instead of providing a spiral disc 32, the flow guide groove 321 is directly formed on the outer wall of the sleeve 31.

[0034] Specifically, multiple stripping elements 33 are configured, and each stripping element 33 can be detachably connected to the sleeve 31 to facilitate individual replacement of damaged stripping elements 33. The multiple stripping elements 33 are divided into two groups along the axial direction of the sleeve 31, with the two groups of stripping elements 33 located at opposite ends of the spiral disk 32. Within each group, the stripping elements 33 are distributed at intervals along the circumference of the sleeve 31.

[0035] Exemplarily, in one embodiment, such as Figure 2 As shown, the number of peeling parts 33 is configured to be six. The six peeling parts 33 are divided into two groups along the axial direction of the sleeve 31. The two groups of peeling parts 33 are located at both ends of the spiral disk 32, and the three peeling parts 33 in each group are distributed at intervals along the circumference of the sleeve 31.

[0036] In one embodiment, such as Figure 1 and Figure 4 As shown, the peeling member 33 includes a cantilever 333 and a friction block 332. One end of the cantilever 333 is connected to the spiral assembly 30, and the other end extends radially along the spiral assembly 30. The friction block 332 is connected to the end of the cantilever 333 away from the spiral assembly 30, and the friction block 332 is provided with an arc surface 331, which is used to abut against the inner wall of the cooling tower heat exchanger. The arc surface 331 can increase the contact area between the peeling member 33 and the inner wall of the anti-scaling and scale removal device 100, thereby dispersing the pressure during the friction process and reducing local wear on the pipe wall.

[0037] Specifically, the width of the cantilever 333 increases along the direction from the main pipe 10 to the helical assembly 30. This facilitates the installation of the friction block 332 on the cantilever 333.

[0038] In one embodiment, the spiral assembly 30 further includes a descaling plate 334, which is fixedly connected to the cantilever 333. One end of the descaling plate 334 protrudes from the arc surface 331 and includes multiple protrusions 341. It is understood that for hard, stubborn scale layers that have already formed, friction from the arc surface 331 alone may be insufficient for complete removal. Because the descaling plate 334 protrudes from the arc surface 331, the protrusions 341 can form sharp point contact with the scale layer, thereby generating concentrated shearing force on the stubborn scale layer during vibration, breaking and scraping away the hard scale layer, thus significantly improving the ability to treat thick and hard scale. Furthermore, the protrusions 341 of the descaling plate 334 can work in conjunction with the friction block 332. The protrusions 341 of the descaling plate 334 first decompose the thick scale into thin scale or debris, and then the friction block 332 thoroughly rubs off the broken thin scale or debris. The fluid washes away the scale layer after it has been peeled off.

[0039] Specifically, the friction block 332 and the descaling plate 334 are detachably connected to the cantilever 333. Each stripping member 33 includes two friction blocks 332 and one descaling plate 334. The two friction blocks 332 are arranged along their own thickness direction, and the descaling plate 334 is disposed between the two friction blocks 332. The friction blocks 332 and the descaling plate 334 can both be made of wear-resistant steel, such as Mn13, engineering ceramics, such as alumina ceramics, or hard alloys, to balance wear resistance and service life.

[0040] The descaling plate 334, protruding from one end of the arc-shaped surface, includes multiple adjacent planes 342. Two adjacent planes 342 are arranged at an obtuse angle and connected to form a protrusion 341. In one embodiment, such as... Figure 2 and Figure 3 As shown, the anti-scaling and scale removal device 100 also includes a fixed sleeve 40 and a retaining ring 50. The fixed sleeve 40 is fixedly sleeved on the outer periphery of the main pipe 10, and the retaining ring 50 is fixedly connected to the fixed sleeve 40. The spiral assembly 30 has an assembly groove 311 at its axial end. The assembly groove 311 has an inner sidewall 312 and an outer sidewall 313 arranged radially opposite to each other. The retaining ring 50 is installed in the assembly groove 311, and the outer ring of the retaining ring 50 abuts against the outer sidewall 313. The inner ring of the retaining ring 50 is in clearance fit with the inner sidewall 312. Furthermore, as the driving member 20 drives the main pipe 10 to vibrate, the spiral assembly 30 can rotate or swing around the main pipe 10 with the abutment point of the outer ring of the retaining ring 50 against the outer sidewall 313 as the fulcrum.

[0041] Understandably, the outer ring of the retaining ring 50 abuts against the outer wall 313 of the assembly groove 311, and the inner ring is in clearance fit with the inner wall 312, forming a rotatable and swingable fulcrum structure. Specifically, when the driving component 20 drives the main pipe 10 to vibrate, it can not only restrict the axial movement of the spiral assembly 30, but also allow the spiral assembly 30 to rotate or swing slightly around the main pipe 10 with the abutment point between the retaining ring 50 and the outer wall 313 as the fulcrum, so that the friction block 332 and the descaling plate 334 can rub the inner wall of the heat exchanger from multiple directions.

[0042] Specifically, a mounting groove 311 is formed at each end of the sleeve 31 along the axial direction, and a retaining ring 50 is installed in each mounting groove 311. This helps to ensure a stable connection between the spiral assembly 30 and the main pipe 10.

[0043] In one embodiment, the anti-scaling and scale removal device further includes a limiting plate 80, which is sandwiched between the outer ring of the retaining ring 50 and the outer side wall 313. The limiting plate 80 can further restrict the axial displacement of the sleeve 31, avoiding wear and functional failure caused by direct contact between the retaining ring 50 and the outer side wall 313 of the assembly groove 311. This is because if the retaining ring 50 directly contacts the outer side wall 313 of the assembly groove 311, the sleeve 31 will quickly contact the outer side wall 313 during vibration and rotation, resulting in a larger gap and loosening or displacement of the sleeve 31, ultimately affecting the anti-scaling and scale removal effect.

[0044] like Figure 5 and Figure 6 As shown, the cooling tower heat exchanger has two installation ports. The anti-scaling and scale removal device further includes a first installation component 60 and a second installation component 70. The first installation component 60 is fixedly connected to one end of the main pipe 10 and is used to install to one of the installation ports. The second installation component 70 is fixedly connected to the other end of the main pipe 10 and is used to install to the other installation port. By setting the first installation component 60 and the second installation component 70 to connect to both ends of the main pipe 10 and correspondingly install them to the two installation ports of the heat exchanger, the anti-scaling and scale removal device 100 forms an assembly structure with both ends fixed, thereby reducing the risk of the anti-scaling and scale removal device 100 falling off. Furthermore, the installation process is simple and does not require large-scale modification of the original cooling tower heat exchanger.

[0045] The first mounting assembly 60 includes a first mounting cylinder 61, a first connector 62, and a first mounting flange 63. The first connector 62 is located inside the first mounting cylinder 61 and is fixedly connected to the inner wall of the first mounting cylinder 61. The first mounting flange 63 is located at the axial end of the first mounting cylinder 61 and is used to connect to a mounting port. It is understood that the first mounting cylinder 61, as the main frame of the first mounting assembly 60, provides sufficient rigid support. The first connector 62, located inside the first mounting cylinder 61, is fixedly connected to the inner wall of the first mounting cylinder 61.

[0046] Specifically, the first connector 62 includes a first connecting plate 621 and a plurality of first support arms 622. The inner ring of the first connecting plate 621 is fixedly connected to the outer periphery of the main pipe 10. One end of each first support arm 622 is connected to the outer ring of the first connecting plate 621, and the other end extends radially along the first connecting plate 621 and is connected to the inner wall of the first mounting cylinder 61.

[0047] Optionally, in one embodiment, two first mounting flanges 63 are configured, with the two first mounting flanges 63 located at opposite ends of the first mounting cylinder 61. A sealing gasket 90 is provided at the connection between each first mounting flange 63 and the mounting port. The sealing gasket 90 is used to improve the assembly seal between the anti-scaling and scale removal device 100 and the cooling tower heat exchanger to prevent fluid leakage.

[0048] The drive unit 20 includes multiple vibration motors 21, which are respectively mounted on the outer wall of the first mounting cylinder 61. This facilitates the maintenance of the vibration motors 21 from the outside of the first mounting cylinder 61. Furthermore, the multiple vibration motors 21 are evenly spaced along the first mounting cylinder 61. This distributed installation method allows the vibration force to be evenly transmitted along the circumference of the first mounting cylinder 61 to the main pipe 10, and then to the helical assembly 30, avoiding uneven vibration force caused by a single vibration motor.

[0049] The second mounting assembly 70 includes a second mounting cylinder 71, a second connector 72, and a second mounting flange 73. The second connector 72 is located inside the second mounting cylinder 71 and is fixedly connected to the inner wall of the second mounting cylinder 71. The second mounting flange 73 is located at the axial end of the second mounting cylinder 71 and is used to connect to a corresponding mounting port. Similarly, the second mounting cylinder 71 serves as the main frame of the second mounting assembly 70, providing sufficient rigid support. The second connector 72, located inside the second mounting cylinder 71, is fixedly connected to the inner wall of the second mounting cylinder 71.

[0050] Specifically, the second connector 72 includes a second connecting plate 721 and a plurality of second support arms 722. The inner ring of the second connecting plate 721 is fixedly connected to the outer periphery of the main pipe 10. One end of each second support arm 722 is connected to the outer ring of the second connecting plate 721, and the other end extends radially along the second connecting plate 721 and is connected to the inner wall of the second mounting cylinder 71.

[0051] Optionally, in one embodiment, two second mounting flanges 73 are configured, with the two second mounting flanges 73 located at opposite ends of the second mounting cylinder 71. A sealing gasket 90 is provided at the connection between each second mounting flange 73 and the mounting port. The sealing gasket 90 is used to improve the assembly seal between the anti-scaling and scale removal device 100 and the cooling tower heat exchanger to prevent fluid leakage.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
