[0028] The present invention will be further described below with reference to embodiments and accompanying drawings: A vertical tube-type integrated mist cooler includes: a vertical shell 1, wherein a condensing chamber 2, a demisting chamber 3, and a manifold chamber 4 are independently arranged within the vertical shell 1; a condensing tube assembly 21 is arranged within the condensing chamber 2; the demisting chamber 3 and the manifold chamber 4 are connected through the condensing tube assembly 21; a first demister 31 is arranged within the demisting chamber 3; external saturated humid gas enters the vertical shell 1 and passes sequentially through the first demister 31 and the condensing tube assembly 21 before being discharged from the manifold chamber 4. The vertical shell 1 includes multiple outer shells connected by flanges or welded together. A first steam-water separator 7 is arranged between the condensing chamber 2 and the first demister 31. A first drain pipe 13 is provided on the vertical shell 1 for discharging intercepted water or backwash water from the first demister 31. The vertical housing 1 is provided with a gas inlet 11 and a gas outlet 12. The vertical housing 1 is also provided with a cooling medium inlet 15 and a cooling medium outlet 16, both of which are connected to the shell side formed between the vertical housing 1 and the condenser tube assembly 21. When the gas outlet 12 is located at the bottom of the lower end of the vertical housing 1, a second steam-water separator 8 is provided in the manifold chamber 4. When the gas inlet 11 is located at the bottom of the lower end of the vertical housing 1, a second steam-water separator 8 is provided in the demisting chamber 3, located on the other side of the first demister 31. A second demister 32 is provided in the manifold chamber 4. A third steam-water separator 9 is also included, positioned below the second demister 32. A flow equalization plate 6 for guiding airflow is provided inside the vertical housing 1. A second drain pipe 14 for discharging condensate generated by the condenser tube assembly 21 is provided on the vertical housing 1. The vertical housing 1 is provided with a third drain pipe 17 for discharging intercepted water or backwash water from the second demister 32. A backwashing mechanism 5 is provided inside the demister chamber 3. The backwashing direction of the backwashing mechanism 5 is the same as the demister direction of the first demister 31.

[0029] The vertical shell 1, serving as the core component for overall support and spatial separation of the equipment, is constructed from multiple shells connected by flanges or welded together. Its main function is to provide the installation foundation and structural protection for the various chambers and components within the equipment. Simultaneously, through reasonable chamber separation (independently setting up a condensation chamber 2, a demisting chamber 3, and a manifold chamber 4), it ensures the orderly operation of the gas processing flow. The flange connection facilitates the disassembly and maintenance of the shell. When internal cleaning, component replacement, or repair is required, the shell can be quickly opened by disassembling the flanges, reducing maintenance difficulty and cost. The welded connection ensures the sealing and structural strength of key parts of the shell, preventing leakage of cooling media or processed gases. This structural design effectively achieves equipment integration, significantly reducing the floor space compared to the original two independent sets of equipment, while simplifying external piping connections and reducing system resistance.

[0030] The condensing chamber 2 is the core space for gas condensation in the equipment. Its main function is to provide an installation environment and heat exchange space for the condenser tube assembly 21, ensuring efficient heat exchange between the cooling medium and the gas to be treated. The condensing chamber 2 is connected to the cooling medium inlet 15 and the cooling medium outlet 16, forming a closed shell-side space. This allows the cooling medium to flow evenly around the condenser tube assembly 21 within the chamber, fully contacting the outer wall of the condenser tubes and carrying away heat from the gas inside the tubes through heat conduction. By rationally designing the chamber volume and internal flow channels, the flow state of the cooling medium can be optimized, avoiding local dead zones and ensuring uniform heat exchange in all areas of the condenser tube assembly 21, thereby improving the overall condensation efficiency. Simultaneously, the closed structure of the condensing chamber 2 prevents cooling medium leakage, ensuring the safety and stability of the equipment operation.

[0031] The demisting chamber 3 is the first processing stage after the gas enters the equipment. Its main function is to perform preliminary demisting and impurity interception on the mist-containing gas, providing pretreatment for subsequent condensation. The chamber contains key components such as a first demister 31 and a backwashing mechanism 5. After the gas to be treated enters the demisting chamber 3 through the gas inlet 11, it first contacts the first demister 31. Through the deflection and collision of the airflow within the demister, the mist, droplets, and some solid impurities in the gas are intercepted and separated. The spatial design of the demisting chamber 3 must match the gas flow rate and the demister's processing capacity to ensure uniform gas distribution within the chamber and avoid excessively high local flow rates that could reduce the demisting effect. Simultaneously, the bottom of the chamber is connected to the first drain pipe 13, which allows for the timely discharge of intercepted liquids and impurities, preventing accumulation and blockage of the flow channels within the chamber and ensuring the continuous and stable operation of the demisting process.

[0032] The manifold chamber 4 is the final stage of the gas treatment process. Its main function is to collect the clean gas after condensation and secondary demisting, ensuring a smooth gas discharge from the equipment, while also collecting condensate and residual droplets generated during the treatment process. Gas treated by the condenser coil 21 enters the manifold chamber 4, where the airflow is buffered and integrated to prevent turbulence or pulsation during gas discharge, reducing impact on subsequent equipment such as the vacuum pump. The second demister 32 and the third steam-water separator 9 installed in the chamber further purify the gas, removing residual mist and droplets, ensuring that the gas discharged from the gas outlet 12 is dry and clean. The bottom of the manifold chamber 4 is connected to the second drain pipe 14 and the third drain pipe 17, which can promptly discharge condensate and prevent liquid interception by the demister, preventing backflow of accumulated liquid and contamination of the treated gas, ensuring stable gas quality at the equipment outlet.

[0033] The condenser tube assembly 21 is the core functional component of the equipment for gas condensation. Located within the condensation chamber 2, it connects at both ends to the demisting chamber 3 and the manifold chamber 4, forming a tube-side channel for gas flow. The condenser tube assembly 21 consists of multiple parallel condenser tubes, made of corrosion-resistant material, effectively handling gases containing corrosive components and extending its service life. Its main function is to condense water vapor in the gas through heat exchange between the inside and outside of the tubes: gas that has undergone preliminary demisting flows inside the tubes, while a cooling medium flows around the outside. Heat is transferred from the high-temperature gas to the low-temperature cooling medium through the tube wall, causing the water vapor in the gas to condense into liquid water. This liquid water adheres to the inner wall of the tubes and flows with the airflow or gravity to the manifold chamber 4, finally being discharged through the second drain pipe 14. The parallel arrangement of multiple condenser tubes significantly increases the heat exchange area, improves the heat exchange per unit time, and enhances the condensation effect. Simultaneously, the reasonable tube spacing design optimizes the flow state of the cooling medium in the shell side, avoiding excessive flow resistance and ensuring the overall operating efficiency of the equipment.

[0034] The first demister 31, located within the demister chamber 3, serves as the first purification barrier after gas enters the equipment. Its main function is to efficiently intercept mist, droplets, and solid impurities in the gas, reducing the risk of contamination and blockage in the subsequent condenser tube assembly 21. When mist-laden gas flows through the demister, the mist and droplets collide under inertial force, gradually condensing into larger droplets. Under gravity, these droplets fall to the bottom of the demister chamber 3 and are discharged through the first drain pipe 13. This structural design features a wide flow velocity adaptability and high demister efficiency, maintaining good demister performance even at high gas flow rates, thereby reducing the equipment's overall size and meeting integrated design requirements. Simultaneously, the use of thin metal sheet material (such as stainless steel) provides high strength and corrosion resistance, allowing it to adapt to complex working conditions and extending its service life.

[0035] The first steam-water separator 7 is located between the condensing chamber 2 and the first demister 31. Its main function is to perform secondary liquid-gas separation on the gas that has undergone preliminary treatment by the first demister 31, collecting the fine droplets generated by the demister and preventing excessive liquid from entering the condenser tube assembly 21 and affecting heat exchange efficiency. Through optimized flow channel design, such as using centrifugal separation or baffle separation principles, the gas rotates or changes direction as it flows through the separator. Under the action of centrifugal force or inertial force, the droplets separate from the gas, adhere to the inner wall of the separator, and drip to the bottom for discharge. The installation of the first steam-water separator 7 reduces the risk of liquid accumulation in the condenser tube assembly 21, prevents liquid film from covering the tube wall and affecting heat conduction, and reduces the resistance generated by liquid flow inside the tubes, ensuring smooth gas flow and improving the overall operating efficiency of the equipment. The first steam-water separator 7 can be any separator that can achieve the above-mentioned effects. The preferred structure is a combination of a conical baffle and an annular water receiving plate. Gas flows through the space between the conical baffle and the annular water receiving plate, while liquid is intercepted by the conical baffle and guided into the annular water receiving plate, and finally discharged through the first drain pipe 13. Other steam-water separators have the same structure as the first steam-water separator 7.

[0036] The location of the second vapor-water separator 8 can be flexibly adjusted according to the layout of the gas inlet 11 and the gas outlet 12. Its main function is to optimize the liquid-gas separation effect for different airflow directions and ensure the dryness of the gas at key nodes. When the gas outlet 12 is located at the bottom of the lower end of the vertical shell 1, the second vapor-water separator 8 in the manifold chamber 4 can separate the gas passing through the condenser tube group 21 to prevent the liquid generated by condensation from flowing downward with the airflow into the second demister 32. When the gas inlet 11 is located at the bottom of the lower end of the vertical shell 1, the second vapor-water separator 8 in the demister chamber 3 is located on the other side of the first demister 31 to collect the condensate or backwash water generated by the first demister 31 and prevent it from affecting the gas entering through the gas inlet 11.

[0037] The second demister 32, located within the manifold chamber 4, is the final purification step before the gas exits the equipment. Its main function is to deeply remove residual trace amounts of mist and droplets from the gas after condensation, ensuring that the gas entering downstream equipment meets high cleanliness standards. Its structural design can refer to the principle of the first demister 31. The second demister 32 compensates for the shortcomings of a single demister or condensation process, solving the problem that condensed gas may re-form mist due to temperature changes, further improving gas dryness. Simultaneously, the intercepted liquid can be discharged through the third drain pipe 17, preventing secondary evaporation and gas contamination within the manifold chamber 4, ensuring stable and reliable final outlet gas quality.

[0038] The third steam-water separator 9 is located below the second demister 32. Its main function is to quickly separate and discharge the liquid intercepted by the second demister 32, preventing liquid from accumulating on the demister surface or flowing back into the gas flow channel. When the droplets intercepted by the second demister 32 condense to a certain size, they drip into the third steam-water separator 9 under gravity. The separator, through optimized internal structure (such as the installation of guide plates and liquid collection tanks), quickly guides the liquid to the third drain pipe 17 for discharge, preventing liquid from stagnating in the manifold chamber 4. The installation of the third steam-water separator 9 enhances the continuous working capability of the second demister 32, prevents liquid accumulation from affecting the demisting efficiency or causing secondary carryover, and further improves the reliability of the equipment.

[0039] Gas inlet 11 is the channel through which the saturated humid gas to be treated enters the equipment. Its main function is to guide the gas smoothly into the demister chamber 3, ensuring that the gas is evenly distributed within the chamber. The size design of gas inlet 11 must match the flow rate of the gas being processed to avoid excessive pressure loss or reduced demister effect due to excessive flow velocity. At the same time, optimizing the inlet position can reduce turbulence when the gas enters, allowing the airflow to flow more evenly through the first demister 31, thereby improving the initial purification efficiency. Gas inlet 11 is usually connected to external pipelines using a flange connection, which facilitates installation and disassembly while ensuring the sealing of the connection to prevent gas leakage that could cause energy loss or environmental pollution.

[0040] Gas outlet 12 is the channel for discharging clean gas after demisting and condensation treatment. Its main function is to smoothly deliver the treated gas to downstream vacuum pumps or other equipment. The outlet location must be coordinated with the installation of components such as the second gas-liquid separator 8 to prevent liquid from being carried in the discharged gas. Gas outlet 12 adopts a flange connection, which facilitates connection with downstream equipment pipelines and ensures a tight seal to prevent clean gas leakage or the entry of external impurities, thus ensuring the safe and stable operation of downstream equipment.

[0041] Both the cooling medium inlet 15 and the cooling medium outlet 16 are connected to the shell side formed between the vertical shell 1 and the condenser tube assembly 21, jointly constituting the cooling medium circulation channel. Their main function is to achieve continuous supply and discharge of the cooling medium, providing cooling capacity for the condensation process. The cooling medium (such as cooling water, coolant, etc.) enters the shell side through the cooling medium inlet 15, flows around the condenser tube assembly 21 within the condensation chamber 2, absorbs heat from the gas inside the tubes through heat exchange, and is then discharged from the cooling medium outlet 16 and returned to the external cooling system for cooling, forming a closed-loop cycle. The design of the inlet and outlet positions needs to optimize the flow path of the cooling medium within the shell side, avoiding short circuits or dead zones, ensuring sufficient contact between the cooling medium and the condenser tube assembly 21, and improving heat exchange efficiency. Simultaneously, the pipe diameters and connection methods of both must match the cooling medium flow rate and pressure requirements to ensure stable operation of the cooling system and provide a continuous cold source for the efficient condensation of the equipment.

[0042] The first drain pipe 13 is installed on the vertical housing 1, connecting to the bottom of the demister chamber 3. Its main function is to promptly drain the liquid (including condensed water from the mist and a mixture of impurities) intercepted by the first demister 31 and the backwash wastewater from the backwashing mechanism 5. Continuous drainage prevents liquid accumulation in the demister chamber 3, avoiding flooding of the first demister 31 and affecting the demister effect. It also prevents impurities from depositing at the bottom of the chamber and causing blockage of the flow channel. The first drain pipe 13 is usually connected to an external sewage system. Its pipe diameter design must meet the maximum drainage requirements, and a valve can be installed to control the drainage timing, facilitating the closure of the drainage channel during equipment maintenance or repair. The installation of this component ensures the cleanliness and unobstructed flow of the demister chamber 3, providing a guarantee for the long-term stable operation of the equipment.

[0043] The second drain pipe 14 is installed on the vertical housing 1, and its main function is to drain the condensate generated during the condensation process of the condenser tube assembly 21. When gas flows inside the condenser tubes, water vapor condenses into liquid water upon contact with the condenser, flowing along the inner wall of the pipe to the bottom of the manifold chamber 4 or the condenser chamber 2, and then exiting the equipment through the second drain pipe 14. Timely drainage of condensate prevents it from stagnating inside the condenser tubes, thus preventing the formation of a liquid film that affects heat transfer efficiency. It also reduces the resistance generated by the liquid flowing inside the tubes, ensuring smooth gas flow. The second drain pipe 14 must be located close to the condensate collection area, and its diameter must be designed to match the condensate volume to ensure timely and thorough drainage, further improving the condensation efficiency and operational stability of the equipment.

[0044] The third drain pipe 17 is installed on the vertical housing 1 and connects to the manifold chamber 4. Its main function is to discharge the liquid intercepted by the second demister 32 and the liquid separated by the third steam-water separator 9. Residual liquid droplets in the gas after deep purification by the second demister 32 are intercepted and discharged through the third drain pipe 17. This component prevents liquid accumulation in the manifold chamber and avoids the liquid being carried back during gas discharge, ensuring that the outlet gas is dry and clean. Simultaneously, the third drain pipe 17 can discharge wastewater generated during backwashing of the second demister, facilitating equipment maintenance and cleaning.

[0045] The flow equalization plate 6 is installed inside the vertical housing 1. Its main function is to guide the airflow, ensuring a more uniform distribution of the gas to be treated as it enters the demister chamber 3 or condenser chamber 2, thus preventing excessively high local flow velocities or turbulent airflow. The flow equalization plate 6 typically employs a perforated plate or grid structure. When gas flows through the flow equalization plate, the airflow is redistributed, reducing eddies and flow deviations, ensuring sufficient contact between the gas and core components such as the first demister 31 and the condenser tube assembly 21, thereby improving demistering and condensation efficiency. Simultaneously, the flow equalization plate 6 reduces noise generated by gas flow, minimizes wear on the internal structure of the equipment due to airflow impact, and extends the equipment's service life. A well-designed perforation ratio and placement of the flow equalization plate can further optimize the airflow state, reduce system resistance, and improve the overall operating performance of the equipment.

[0046] The backwashing mechanism 5 is located within the demister chamber 3. Its main function is to periodically clean the first demister 31, removing impurities and dirt adhering to its surface, restoring its demisting efficiency, and reducing manual maintenance costs. The backwashing mechanism 5 operates in the same direction as the demisting process of the first demister 31; the washing medium (usually water or compressed air) is sprayed along the gas flow direction, causing the adhering impurities to detach from the surface under impact and be discharged with the washing wastewater through the first drain pipe 13. This design ensures more thorough washing and prevents impurities from being flushed towards the gas inlet side, causing secondary pollution. The backwashing mechanism 5 can be automated to perform periodic washing, allowing maintenance without shutdown, ensuring continuous and stable equipment operation, and solving the problem of difficult cleaning of the original equipment. Working process.

[0047] Operating Condition 1:

[0048] The saturated humid gas to be treated enters the demister chamber 3 through the gas inlet 11 (located at the upper end of the shell) of the vertical shell 1. After being guided by the flow equalization plate 6, the airflow is evenly distributed. The gas first flows through the first demister 31, where mist, droplets and impurities are intercepted. The condensed droplets fall with gravity and are discharged through the first drain pipe 13. The backwashing mechanism 5 can periodically rinse the surface of the first demister in the same direction to remove impurities, and the wastewater is also discharged through the first drain pipe 13.

[0049] After initial demisting, the gas enters the first steam-water separator 7, where residual droplets are further separated before flowing into the condenser tube assembly 21. At this time, the cooling medium enters the shell side formed by the vertical shell 1 and the condenser tube assembly 21 from the cooling medium inlet 15, flows around the condenser tubes in the condensation chamber 2, and carries away the heat of the gas in the tubes through heat exchange, causing the water vapor in the gas to condense into liquid water. The condensate flows along the inner wall of the tubes to the manifold chamber 4.

[0050] The condensed gas enters the manifold chamber 4, where it is first deeply intercepted by the second demister 32 to remove trace amounts of mist. The intercepted droplets fall to the third steam-water separator 9 and are discharged through the third drain pipe 17. Finally, the clean gas is discharged through the gas outlet 12 (located at the lower end of the shell). The second steam-water separator 8 in the manifold chamber prevents residual liquid from being discharged with the airflow. The condensate generated by the condenser tube is discharged through the second drain pipe 14.

[0051] Operating Condition 2:

[0052] The saturated humid gas to be treated enters the demister chamber 3 from the gas inlet 11 (located at the bottom of the lower end of the shell) of the vertical shell 1. It first flows through the second steam-water separator 8 located on the other side of the first demister 31, which initially separates a large amount of liquid in the gas, reducing the processing load of the first demister. The separated liquid is discharged through the first drain pipe 13.

[0053] After pretreatment, the gas is guided by the flow equalization plate 6 and flows through the first demister 31 to intercept mist and impurities. The condensed droplets are discharged through the first drain pipe 13. The backwashing mechanism 5 periodically washes the surface of the demister and discharges wastewater simultaneously.

[0054] The gas then enters the first steam-water separator 7 for secondary separation of residual droplets or to receive the liquid condensed from the condenser tube assembly 21, before flowing back into the tubes of the condenser tube assembly 21. The cooling medium enters the shell side from the cooling medium inlet 15, exchanges heat with the gas inside the tubes in the condenser chamber 2, and the water vapor condenses into water, which flows upward along the inner wall of the tubes into the manifold chamber 4.

[0055] The condensed gas enters the manifold chamber 4, is deeply demisted by the second demister 32, and the intercepted droplets are collected by the third steam-water separator 9 and discharged through the third drain pipe 17; finally, the clean gas is discharged from the gas outlet 12 (located at the upper end of the shell), and the condensate generated by the condenser tube is discharged through the second drain pipe 14.
