Abstract
Description
Technical Field
[0001] This utility model relates to the field of condenser technology, and in particular to a shell-and-tube condenser. Background Technology
[0002] As a type of heat exchange equipment, the core principle of a shell-and-tube condenser is to utilize the contact between the cooling medium and the hot fluid on the inner and outer walls of the tube bundle to achieve heat transfer, thereby achieving the purpose of cooling or condensation. Due to its simple structure, ease of manufacturing, and good heat transfer effect, this type of condenser has been widely used in many industries such as chemical, pharmaceutical, food, beverage, petrochemical, tobacco, textile, and metallurgy. However, with the continuous development of industrial technology, the performance requirements for shell-and-tube condensers are also becoming increasingly stringent. Traditional shell-and-tube condensers have certain shortcomings: inconvenient maintenance. Traditional shell-and-tube condensers usually adopt an integral design. If a cooling tube fails, the entire equipment needs to be completely disassembled for repair, requiring the replacement of all cooling tubes, which is difficult and time-consuming. Furthermore, the heat exchange efficiency needs improvement. Although shell-and-tube condensers have good heat transfer effects, the flow path of the cooling medium inside the cooling tubes is direct along the cooling tubes, resulting in a short flow length. The cooling medium is discharged from the cooling tubes before sufficient thermal contact with the high-heat medium, leading to low heat exchange efficiency and low utilization of the cooling medium. Utility Model Content
[0003] This invention proposes a shell-and-tube condenser to solve the problem that existing equipment requires complete disassembly for repair when it malfunctions.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a shell-and-tube condenser, comprising a shell component, wherein a first conveying channel for conveying cooling medium along a first preset path and a second conveying channel for conveying high-heat medium along a second preset path are formed on the shell component, wherein the liquid inlet section and liquid outlet end of the first conveying channel and the liquid inlet section and liquid outlet end of the second conveying channel are both located inside the shell component, and the first conveying channel and the second conveying channel are not connected.
[0005] The housing component has two detachable end plates screwed together internally, with multiple cooling pipes arranged between the two end plates. Both end plates are open to form multiple liquid guiding holes. Both ends of the cooling pipes are fixedly connected to connecting pipes, which are detachably screwed together with the liquid guiding holes. Part of the first delivery channel is located inside the cooling pipe.
[0006] Preferably, a spiral plate is fixedly connected inside the cooling pipe along its length.
[0007] Preferably, multiple partitions are sleeved between the multiple cooling pipes, and the partitions are provided with a first through hole and a second through hole, and multiple connecting holes are provided on the partitions, and the connecting holes are matched with the cooling pipes one by one.
[0008] Preferably, the shell component includes a tank body, with a first end cap and a second end cap screwed onto both ends of the tank body, and both end plates screwed onto the inside of the tank body;
[0009] A first inlet pipe and a first outlet pipe are fixedly connected to the circumference of the tank body. The first inlet pipe and the first outlet pipe are connected to the inside of the tank body. A second inlet pipe is fixedly connected to one side of the first end cap, and a second outlet pipe is fixedly connected to one side of the second end cap.
[0010] Preferably, a sealing gasket is adhered to the inner wall of the connecting hole.
[0011] Preferably, both the first end cap and the second end cap are fitted with sealing rings on their circumferential surfaces.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] (1) By setting up cooling pipes, connecting pipes, end plates and liquid guide holes, the connecting pipes are screwed into the liquid guide holes to fix the cooling pipes between the two end plates. When personnel need to replace the cooling pipes, they only need to reverse the cooling pipes to separate the connecting pipes from the liquid guide holes, and then remove the corresponding damaged cooling pipes for replacement. There is no need to completely disassemble the entire equipment for maintenance, and there is no need to replace all the cooling pipes, which reduces the difficulty of maintenance and saves time and costs.
[0014] (2) By setting a spiral plate inside the cooling pipe, when the cooling medium is transported to the inside of the cooling pipe, the spiral plate will cooperate to extend the length of the flow path of the cooling medium, thereby extending the heat exchange time between the cooling medium and the high-heat medium, thus improving the condensation efficiency of the high-heat medium, improving the heat exchange efficiency of the device, and improving the utilization rate of the cooling medium.
[0015] (3) By setting up baffles, multiple baffles are connected to multiple cooling pipes through connecting holes. The high heat medium can flow inside the tank through the cooperation of the first through hole and the second through hole, thereby extending the heat exchange time between the high heat medium and the cooling medium, further improving the heat exchange efficiency of the device, and further improving the utilization rate of the cooling medium.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figures 1-6 As shown, a shell-and-tube condenser includes a shell component, on which a first conveying channel for conveying cooling medium along a first preset path and a second conveying channel for conveying high-heat medium along a second preset path are formed. The liquid inlet section and liquid outlet end of the first conveying channel and the liquid inlet section and liquid outlet end of the second conveying channel are both located inside the shell component, and the first conveying channel and the second conveying channel are not connected.
[0026] The housing has two detachable end plates 8 screwed together internally. Multiple cooling pipes 10 are arranged between the two end plates 8, and multiple liquid guiding holes 9 are formed on both end plates 8. Both ends of the cooling pipes 10 are fixedly connected to connecting pipes 13, which are detachably screwed together with the liquid guiding holes 9. Part of the first delivery channel is located inside the cooling pipes 10.
[0027] With the above technical solution, before the high-temperature medium needs to be condensed, the cooling pipe 10 is rotated, causing the connecting pipe 13 to rotate. This allows the connecting pipe 13 to engage with the liquid guide hole 9 on the end plate 8, thus fixing the cooling pipe 10 to the end plate 8. The end plate 8 is then connected to the housing component, completing the installation of the cooling pipe 10. The pipe for conveying the high-temperature medium is connected to the second conveying channel on the housing component, and the pipe for conveying the cooling medium is connected to the first conveying channel on the housing component. After both the high-temperature medium and the cooling medium are conveyed into the housing component, the end plate 8, in conjunction with... The cooling medium is delivered through the liquid guide hole 9 to the interior of multiple cooling pipes 10, allowing the high-heat medium and the cooling medium to exchange heat through the cooling pipes 10, thereby reducing the temperature of the high-heat medium and causing it to condense. The high-temperature medium is discharged through the first conveying channel and the high-temperature medium is discharged through the second conveying channel. When the cooling pipe 10 needs to be replaced, the end plate 8 is rotated to separate the end plate 8 from the housing, and then the cooling pipe 10 is rotated, which causes the connecting pipe 13 to rotate, separating the connecting pipe 13 from the liquid guide hole 9 on the end plate 8, so that the cooling pipe 10 can be removed for replacement.
[0028] To extend the length of the cooling medium flow path, such as Figure 5 As shown, a spiral plate 14 is fixedly connected inside the cooling pipe 10 along its own length.
[0029] In this embodiment, after the cryogenic medium is transported into the interior of the cooling pipe 10, it is engaged with the spiral plate 14 to increase the length of the flow path during the flow of the cryogenic medium, prolong the heat exchange time between the cryogenic medium and the high-temperature medium, thereby improving the heat exchange efficiency and increasing the utilization rate of the cryogenic medium.
[0030] Furthermore, in this invention, in order to increase the heat exchange time between the high-heat medium and the cooling medium, such as... Figures 1-4 As shown, multiple partitions 11 are sleeved between multiple cooling pipes 10. The partitions 11 have a first through hole 12 and a second through hole 15, and multiple connecting holes 16 are provided on the partitions 11. The connecting holes 16 are matched with the cooling pipes 10 one by one.
[0031] In this embodiment, before using the device, multiple partitions 11 are fitted between multiple cooling pipes 10 through connection holes 16. When the high-temperature medium flows into the housing, the partitions 11 cooperate to further increase the heat exchange time between the high-heat medium and the low-temperature medium inside the cooling pipe 10, thereby further improving the condensation efficiency of the high-heat medium.
[0032] Specifically, in one embodiment, regarding the aforementioned housing component, such as Figures 1-4 As shown, the shell component includes a tank body 1, with a first end cap 4 and a second end cap 6 screwed onto both ends of the tank body 1, and two end plates 8 screwed onto the inside of the tank body 1.
[0033] A first inlet pipe 2 and a first outlet pipe 3 are fixedly connected to the periphery of the tank body 1. The first inlet pipe 2 and the first outlet pipe 3 are connected to the inside of the tank body 1. A second inlet pipe 5 is fixedly connected to one side of the first end cap 4, and a second outlet pipe 7 is fixedly connected to one side of the second end cap 6.
[0034] In this embodiment, after the end plate 8 is connected to the cooling pipe 10, the cooling pipe 10 and the end plate 8 are installed inside the tank body 1. Then, the first end cap 4 and the second end cap 6 are screwed together with the tank body 1 to complete the assembly of the device. The pipe for inputting the high-heat medium is connected through the first liquid inlet pipe 2, and the pipe for transporting the low-temperature medium is connected through the second liquid inlet pipe 5. The cooling medium is input into the inside of the first end cap 4 through the second liquid inlet pipe 5. The cooling medium is guided to the inside of the cooling pipe 10 through the liquid guide hole 9. The high-heat medium is guided to the inside of the tank body 1 through the first liquid inlet pipe 2. The high-heat medium comes into contact with the surface of the cooling pipe 10 to exchange heat and condense the high-heat medium.
[0035] After the cooling pipe 10 is connected to the connection hole 16 on the partition plate 11, in order to increase the sealing between the surface of the cooling pipe 10 and the connection hole 16, such as Figure 6 As shown, a sealing gasket 17 is bonded to the inner wall of the connection hole 16.
[0036] In this embodiment, after the cooling pipe 10 is connected to the connection hole 16, the sealing gasket 17 is used to increase the sealing at the connection between the cooling pipe 10 and the connection hole 16, thereby preventing leakage at the connection between the cooling pipe 10 and the connection hole 16.
[0037] Furthermore, in this utility model, after the first end cap 4 and the second end cap 6 are connected to the tank body 1, in order to increase the sealing between the first end cap 4 and the second end cap 6 and the tank body 1, sealing rubber rings are fitted on the circumferential surfaces of the first end cap 4 and the second end cap 6.
[0038] In this embodiment, after the first end cap 4 and the second end cap 6 are connected to the tank body 1, the sealing effect between the first end cap 4 and the second end cap 6 and the tank body 1 is increased by the cooperation of the sealing rubber ring, thereby reducing the probability of leakage at the connection between the first end cap 4 and the second end cap 6 and the tank body 1.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
