Description

Technical Field

[0001] This utility model relates to the field of condenser technology, and more specifically, to a tubular condenser. Background Technology

[0002] Tubular condensers, as the core heat exchange equipment for cooling and phase change of materials in industrial production, are widely used in chemical, pharmaceutical, food processing, and refrigeration fields. Their performance directly affects production efficiency, product quality, and energy consumption levels. As industrial production develops towards higher efficiency, lower energy consumption, and higher adaptability, the condenser technology continues to evolve.

[0003] During use, existing mechanisms often result in residues on the inner walls of the tubes, and the cleaning method involves rinsing with water, which is not thorough. These residues on the inner walls lead to low condensation efficiency in the condenser. A search revealed that Chinese patent CN221037067U discloses a shell-and-tube condenser. When cleaning the condenser, the sealing cap on the feed pipe is opened, a cleaning agent is added to the condensing chamber, and then the water inlet valve is opened to flush the condensing chamber. After flushing, the flushing wastewater is discharged from the three-way discharge pipe. Then, the screw motor rotates to drive the cleaning plate to move along the condensing tubes and the inner wall of the condensing chamber, scraping off the residue on the condensing tubes and the inner wall of the condensing chamber and discharging it from the three-way discharge valve, thus facilitating the cleaning of the inside of the condenser.

[0004] However, in actual use, this structure uses a single baffle to guide the flow of coolant, resulting in a short effective contact time with the heat exchange tubes. Furthermore, the fixed baffle layout and uneven flow velocity in some areas can easily lead to heat exchange dead zones, resulting in insufficient heat exchange and directly affecting condensation efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tubular condenser to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tubular condenser includes an outer shell and an end cap assembly. A left end shell tube sheet and a right end shell tube sheet are respectively fixedly disposed at both ends of the outer shell. A flow channel assembly is disposed inside the outer shell. The flow channel assembly includes a baffle plate, a fixing rod, a flow guide ring, and heat exchange tube holes. The surface of the baffle plate has multiple heat exchange tube holes and fixing rod holes. The fixing rod is fixedly connected to the fixing rod holes. A heat exchange tube is installed inside the heat exchange tube holes. A flow guide ring is sandwiched between adjacent baffle plates. The flow guide ring is a nitrile rubber ring and is interference-fitted with the fixing rod. An insulation layer is fixedly provided on the outer wall of the outer shell.

[0007] By adopting the above technical solutions, the contact time between the coolant and the heat exchange tube is extended, significantly improving the heat exchange efficiency. The insulation layer on the outer wall of the outer shell can reduce heat loss and further ensure the heat exchange effect.

[0008] As a further description of the above technical solution: the end cap assembly includes a left end cap, a right end cap, an exhaust port, a material inlet and a material outlet. The left end cap and the right end cap are hemispherical head structures with an anti-corrosion coating on the inner wall. The exhaust port is located at the top of the left end cap and has a built-in stainless steel filter screen. The material inlet and material outlet are located on both sides of the right end cover and are connected to the right end cover.

[0009] By adopting the above technical solution: the anti-corrosion layer sprayed on the inner wall can isolate the material from direct contact with the metal material of the end cap, avoid the material from corroding the end cap, extend the service life of the end cap, prevent the end cap from rusting and contaminating the material, ensure the purity of the material after condensation, and the material inlet and outlet are located on both sides of the right end cap and connected to the end cap, which facilitates the centralized entry and exit of materials, simplifies pipeline connection, and is also conducive to subsequent maintenance and repair of the inlet and outlet.

[0010] As a further description of the above technical solution: the left end shell tube sheet is sealed to the left end cover through the left end cover flange, and the right end shell tube sheet is sealed to the right end cover through the right end cover flange. A cooling water inlet is connected to one side of the outer casing, and a cooling water outlet is connected to the other side of the outer casing; Flange sealing gaskets are provided at the connection between the left end cover and the left end cover flange, and between the right end cover and the right end cover flange. Standardized flanges are fixedly installed at the ports of the material inlet and the material outlet. A support is fixedly provided on the outer wall of the outer shell, and an anti-slip pad is fixedly provided on the bottom of the support; A ball valve is installed at the outlet end of the exhaust port, and the nominal diameter of the ball valve is adapted to the inner diameter of the exhaust port.

[0011] By adopting the above technical solution, the tube sheet and end cap are connected by flanges and sealing gaskets. The double sealing structure greatly improves the equipment's sealing performance, effectively reduces the risk of material or cooling water leakage, and can flexibly connect to external pipelines of different specifications, adapt to various production scenarios, and reduce equipment adaptation costs.

[0012] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts a flow channel assembly. The guide ring is made of nitrile rubber and is interference-fitted with the fixing rod. It can work with the baffle to guide the coolant to form a tortuous flow channel in the shell, avoiding excessively fast or slow local flow rates. At the same time, it extends the contact time between the coolant and the heat exchange tube. Combined with the heat insulation layer on the outer wall of the shell, it further reduces heat loss. In addition, this innovative design does not require additional power to drive it. The flow channel is controlled only through structural optimization, which reduces the energy consumption of the equipment and reduces the local wear of the heat exchange tube caused by uneven flow rate. This indirectly extends the service life of the equipment, reduces maintenance costs, and meets the high-efficiency condensation requirements of high-load industrial production. 2. The connection between the left end cover and the left end cover flange, and the connection between the right end cover and the right end cover flange of this utility model are all sealed with flange gaskets. Combined with the argon arc welding of the two ends of the outer shell to the tube sheet, the sealing performance is doubly guaranteed. The material inlet and outlet ports adopt standardized flanges, which can flexibly connect to material conveying pipelines of different specifications, easily switch coolant or heat source, and adapt to the condensation requirements of various materials. At the same time, the exhaust port has a built-in stainless steel filter screen and a ball valve, which not only prevents impurities from entering the equipment and affecting the condensation effect, but also controls the gas emission as needed, improves the operational flexibility, and meets the usage needs of diverse industrial production scenarios.

[0019] 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.

[0020] The embodiments disclosed in this application are as follows: Figure 1-5 The tubular condenser shown includes an outer shell 1 and an end cap assembly. A left end shell tube plate 2 and a right end shell tube plate 3 are respectively fixedly installed at both ends of the outer shell 1. A flow channel assembly is provided inside the outer shell 1. The flow channel assembly includes a baffle plate 4, a fixing rod 5, a flow guide ring 6, and a heat exchange tube hole 7. The surface of the baffle plate 4 is provided with multiple heat exchange tube holes 7 and fixing rod holes 8. The fixing rod 5 is fixedly connected to the fixing rod hole 8. A heat exchange tube 9 is installed inside the heat exchange tube hole 7. A flow guide ring 6 is sandwiched between adjacent baffle plates 4. The flow guide ring 6 is a nitrile rubber ring and is interference-fitted with the fixing rod 5. An insulation layer 10 is fixedly provided on the outer wall of the outer shell 1. After the material enters the right end cover 12, it is diverted to the interior of each heat exchange tube 9. The heat exchange tube 9 is installed in the heat exchange tube hole 7 of the baffle plate 4 and is kept stable by the fixed connection between the fixing rod 5 and the fixing rod hole 8. When the material flows inside the heat exchange tube 9, it exchanges heat with the coolant in the shell. The heat carried by the material is transferred to the coolant through the tube wall of the heat exchange tube 9, achieving cooling and condensation of the material. Moreover, the baffle plate 4 and the guide ring 6 work together to form a tortuous flow channel for the coolant in the shell, prolonging the contact time with the heat exchange tube 9. At the same time, the insulation layer 10 is a rock wool insulation layer. The insulation layer 10 on the outer wall of the outer shell 1 reduces heat loss and improves heat exchange efficiency.

[0021] Reference Figure 2-3 As shown, the end cap assembly includes a left end cap 11, a right end cap 12, an exhaust port 13, a material inlet 14, and a material outlet 15. The left end cap 11 and the right end cap 12 are hemispherical end cap structures with an anti-corrosion coating 16 on their inner walls. The exhaust port 13 is located on the top of the left end cap 11 and has a built-in stainless steel filter screen 17. Material inlet 14 and material outlet 15 are located on both sides of right end cover 12 and are connected to right end cover 12. Confirm that the flange gaskets 22 at the connection between the left end cover 11 and the left end cover flange 18, and the right end cover 12 and the right end cover flange 19 are intact, without damage or aging, and ensure that there is no leakage at the connection. Then, ensure that the ball valve 25 at the outlet end of the exhaust port 13 is closed to prevent material or coolant leakage. Check the pipeline valves of the cooling water inlet 20, cooling water outlet 21, material inlet 14 and material outlet 15 to ensure that they are in the ready-to-open state. Ensure that the outer wall support 23 and the bottom anti-slip pad 24 of the outer shell 1 are firmly installed to prevent vibration and displacement during equipment operation. Next, coolant is introduced through the cooling water inlet 20 on one side of the outer shell 1. The coolant flows along the inner shell layer of the outer shell 1 and is guided by the baffle 4 and the guide ring 6 to form a stable flow channel. The guide ring 6 is a nitrile rubber ring that is interference-fitted with the fixing rod 5 to optimize the coolant flow path and avoid uneven local flow velocity.

[0022] Reference Figure 4-5 As shown, the left end shell tube sheet 2 is sealed to the left end cover 11 through the left end cover flange 18, and the right end shell tube sheet 3 is sealed to the right end cover 12 through the right end cover flange 19. A cooling water inlet 20 is connected to one side of the outer casing 1, and a cooling water outlet 21 is connected to the other side of the outer casing 1; Flange gaskets 22 are provided at the connection between the left end cover 11 and the left end cover flange 18, and the right end cover 12 and the right end cover flange 19. Standardized flanges are fixedly installed at the ports of the material inlet 14 and the material outlet 15. A support 23 is fixedly installed on the outer wall of the outer shell 1, and an anti-slip pad 24 is fixedly installed on the bottom of the support 23; A ball valve 25 is installed at the outlet end of the exhaust port 13, and the nominal diameter of the ball valve 25 is adapted to the inner diameter of the exhaust port 13. A small amount of gas generated during the material condensation process is discharged through the exhaust port 13 at the top of the left end cover 11. The exhaust port 13 has a built-in stainless steel filter screen 17 to filter impurities. The ball valve 25 needs to be opened periodically to discharge the gas to avoid excessive pressure inside the shell. After heat exchange, the coolant is discharged from the cooling water outlet 21 on the other side of the outer shell 1 and enters the subsequent circulation or processing system. The material cooled by the heat exchange tube 9 is collected inside the left end cover 11 and then discharged through the material outlet 15 on the other side of the right end cover 12, thus realizing the collection of condensed material. After the material condensation process is completed, first close the valves of material inlet 14 and cooling water inlet 20. After the residual medium in the equipment is discharged, close the outlet valve and finally close the ball valve 25 to complete one working cycle.

[0023] Working principle of this utility model: This utility model is a tubular condenser. When using the device, ensure that the flange sealing gasket 22 at the connection between the left end cover 11 and the left end cover flange 18, and the right end cover 12 and the right end cover flange 19 is intact, without damage or aging, and ensure that there is no leakage at the connection. Then, keep the ball valve 25 at the outlet end of the exhaust port 13 closed to prevent material or coolant leakage. Check the pipeline valves of the cooling water inlet 20, cooling water outlet 21, material inlet 14 and material outlet 15 to ensure that they are in the ready-to-open state. The outer wall support 23 and the bottom anti-slip pad 24 of the outer shell 1 are firmly installed to prevent vibration and displacement during equipment operation. Next, coolant is introduced through the cooling water inlet 20 on one side of the outer shell 1. The coolant flows along the inner shell layer of the outer shell 1 and is guided by the baffle 4 and the guide ring 6 to form a stable flow channel. The guide ring 6 is a ring-shaped part of nitrile rubber and is interference-fitted with the fixed rod 5 to optimize the flow path of the coolant and avoid uneven local flow velocity. Then, the material to be condensed is introduced through the material inlet 14 on one side of the right end cover 12. After the material enters the right end cover 12, it is diverted to the inside of each heat exchange tube 9. The heat exchange tube 9 is installed in the heat exchange tube hole 7 of the baffle plate 4 and is kept stable by the fixed connection between the fixing rod 5 and the fixing rod hole 8. When the material flows inside the heat exchange tube 9, it exchanges heat with the coolant in the shell. The heat carried by the material is transferred to the coolant through the tube wall of the heat exchange tube 9, thereby cooling and condensing the material. In addition, the baffle plate 4 and the guide ring 6 work together to form a tortuous flow channel for the coolant in the shell, which prolongs the contact time with the heat exchange tube 9. At the same time, the insulation layer 10 is a rock wool insulation layer. The insulation layer 10 on the outer wall of the outer shell 1 reduces heat loss and improves heat exchange efficiency. A small amount of gas generated during the material condensation process is discharged through the exhaust port 13 at the top of the left end cover 11. The exhaust port 13 has a built-in stainless steel filter screen 17 to filter impurities. The ball valve 25 needs to be opened periodically to discharge the gas to avoid excessive pressure inside the shell. After heat exchange, the coolant is discharged from the cooling water outlet 21 on the other side of the outer shell 1 and enters the subsequent circulation or processing system. The material cooled by the heat exchange tube 9 is collected inside the left end cover 11 and then discharged through the material outlet 15 on the other side of the right end cover 12, thus realizing the collection of condensed material. After the material condensation process is completed, first close the valves of material inlet 14 and cooling water inlet 20. After the residual medium in the equipment is discharged, close the outlet valve and finally close the ball valve 25 to complete one working cycle. During subsequent maintenance, the left end cover 11 and the right end cover 12 should be disassembled periodically via the flange connection to clean the inner wall of the heat exchange tube 9 and the inner wall of the end cover. The anti-corrosion layer 16 sprayed on the inner wall of the end cover is a polytetrafluoroethylene anti-corrosion layer. During cleaning, care should be taken to avoid damaging this coating.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
