Description

Technical Field

[0001] This utility model belongs to the field of energy-saving and environmental protection technology, and in particular relates to a horizontal tube-type integrated mist cooler. Background Technology

[0002] During the operation of vacuum pumps or other equipment, the gas being pumped often contains a large amount of mist, impurities, and water vapor. These materials, once inside the vacuum pump or other equipment, can reduce its efficiency. If the materials contain corrosive chemicals, they can cause long-term corrosion, shortening the pump's or equipment's lifespan. Furthermore, particulate impurities can adhere to the pump chamber or rotor surface, leading to increased friction and scratches over time, compromising sealing and reducing pumping capacity. For example, in industries such as chemical production, food processing, and pharmaceuticals, vacuum pumps need to handle gases containing mist and water vapor; without an effective demisting and condensation device, production will suffer adverse consequences.

[0003] The current equipment consists of two independent units: a demister and a condenser. The demister is large in size, and its piping is extensive and compatible with the condenser, which increases costs and reduces installation efficiency. Utility Model Content

[0014] The beneficial effects of this utility model are:

[0015] This application integrates demisting and condensation functions into a horizontal housing, replacing the original two separate units, reducing connecting pipelines and energy consumption, and lowering gas flow resistance. The horizontal structure significantly reduces the floor space, and the flange or welded connections ensure both ease of assembly and disassembly and sealing, solving the problems of large footprint and complex piping in traditional equipment.

[0016] This application utilizes a three-stage treatment process: a first demister to initially intercept impurities, a condenser tube assembly for heat exchange and dehydration, a second demister for deep purification, and finally, a third stage to efficiently remove mist, water vapor, and impurities.

[0024] The present invention will be further described below with reference to embodiments and accompanying drawings: A horizontal tube-side integrated mist cooler includes: a horizontal shell 1, wherein a condensing chamber 2, a demisting chamber 3, and a manifold chamber 4 are independently arranged within the horizontal 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 horizontal shell 1 and passes sequentially through the first demister 31 and the tubes of the condensing tube assembly 21 before being discharged from the manifold chamber 4. The horizontal shell 1 includes multiple outer shells connected by flanges or welded together. A gas inlet 11 and a gas outlet 12 are provided on the horizontal shell 1; a cooling medium inlet 15 and a cooling medium outlet 16 are provided on the horizontal shell 1; both the cooling medium inlet 15 and the cooling medium outlet 16 are connected to the shell side formed between the horizontal shell 1 and the condensing tube assembly 21. The horizontal housing 1 is equipped with a first drain pipe 13 for discharging intercepted water or backwash water from the first demister 31, and a second drain pipe 14 for discharging condensate generated by the condenser tube assembly 21. The demisting direction of the first demister 31 is parallel or perpendicular to the flow direction of the medium within the condenser tube assembly 21. A backwashing mechanism 5 is installed inside the demisting chamber 3. The backwashing direction of the backwashing mechanism 5 is the same as the demisting direction of the first demister 31. A second demister 32 is installed inside the confluence chamber 4. The condenser tube assembly 21 or the horizontal housing 1 is inclined relative to the ground. A flow equalization plate 6 for guiding airflow is installed inside the horizontal housing 1.

[0025] The horizontal shell 1, serving as the foundational load-bearing structure of the entire mist cooler, is the core carrier of the integrated equipment design. Its horizontal structure, unlike the original vertical equipment, significantly reduces the installation height requirements, greatly saving floor space and solving the problems of inconvenient installation and large footprint of the original vertical demisting devices. The shell is composed of multiple outer shells connected by flanges or welded. The flange connection allows for flexible disassembly of the shell, facilitating subsequent cleaning, maintenance, and repair of the internal chambers and components, reducing labor and time costs during maintenance. The welded connection ensures the overall sealing and structural strength of the shell, guaranteeing that there will be no gas leakage or cooling medium seepage during operation.

[0026] The horizontal housing 1 is internally divided into a condensation chamber 2, a demisting chamber 3, and a gas collection chamber 4, achieving integrated functions of demisting, condensation, and gas collection. This integrated design combines the functions of two separate sets of equipment into one housing, reducing the connecting pipelines between the equipment and lowering the friction resistance of the gas during flow, thus solving the problems of numerous pipelines and high resistance in the original equipment. Simultaneously, the integrated structure reduces energy loss during pipeline transmission, improving energy efficiency and meeting energy conservation and environmental protection requirements. Furthermore, the horizontal housing 1 provides a stable working environment for all internal components, protecting them from external environmental interference and ensuring the stability and reliability of the equipment operation.

[0027] The condensation chamber 2 is the key area for realizing the gas condensation function. Located inside the horizontal shell 1, its core function is to provide installation space and working environment for the condenser tube assembly 21, ensuring the efficient operation of the condensation process. The condensation chamber 2 is independent of the demister chamber 3 and the manifold chamber 4, avoiding mutual interference between gases and liquids in different processing stages and ensuring the independence and stability of the condensation process.

[0028] In the gas handling process, the gas, after preliminary demisting in the demisting chamber 3, enters the condenser tube assembly 21 in the condensing chamber 2. The gas is guided to flow orderly through the condenser tube assembly 21, ensuring sufficient contact between the gas and the condenser tube assembly 21. Simultaneously, a shell-side space is formed between the condensing chamber 2 and the horizontal shell 1. This space communicates with the cooling medium inlet 15 and the cooling medium outlet 16, allowing the cooling medium to flow around the condenser tube assembly 21 outside the chamber, providing a continuous and uniform cooling environment and ensuring condensation efficiency. The independent design of the condensing chamber 2 also facilitates individual monitoring and maintenance of the condensation process. When cleaning or repairing the condenser tube assembly 21 is required, it can be directly operated by opening the corresponding shell section, improving maintenance convenience.

[0029] The demisting chamber 3 is the first processing area after the gas enters the equipment. Its main function is to perform preliminary demisting treatment on the incoming saturated humid gas, removing most of the mist, droplets, and larger particulate impurities from the gas. As a gas pretreatment stage, the demisting chamber 3 effectively reduces the workload of the subsequent condenser tube assembly 21, preventing a large number of impurities from directly entering the condenser tube assembly 21 and causing blockage. This solves the problem of increased friction and reduced pumping capacity caused by impurities adhering to the original equipment.

[0030] The demisting chamber 3 is equipped with a first demister 31 and a backwashing mechanism 5. Its spatial structure is designed according to the gas flow rate and demisting requirements to ensure that the gas can flow evenly through the first demister 31 and improve the demisting efficiency. The bottom of the demisting chamber 3 is connected to the first drain pipe 13, so that the liquid and impurities intercepted by the first demister 31 can be discharged smoothly, avoiding accumulation in the chamber and affecting the demisting effect.

[0031] The manifold chamber 4, located on the outlet side of the condenser tube assembly 21, is the final stage of gas treatment. Its main function is to collect the condensed gas and perform final demisting and purification. The gas condensed by the condenser tube assembly 21 enters the manifold chamber 4. The spatial structure of the chamber reduces the gas flow rate, facilitating the settling of residual droplets in the gas. At the same time, it provides installation and working space for the second demister 32 to further remove trace amounts of mist from the gas, ensuring that the gas discharged from the gas outlet 12 is dry and clean.

[0032] The design of the manifold chamber 4 ensures stable gas flow, preventing turbulence at the outlet and reducing resistance losses. The bottom of the chamber connects to the second drain pipe 14, allowing for timely discharge of condensate from the condenser coil assembly 21 and liquid intercepted by the second demister 32, preventing backflow of liquid into the condenser coil assembly 21 or into subsequent vacuum pump equipment. The manifold chamber 4 further refines the gas processing flow, improves the overall demisting and condensation effect of the equipment, and provides a more reliable gas intake guarantee for subsequent equipment.

[0033] The condenser tube assembly 21 is the core component for achieving gas condensation. It is located within the condensation chamber 2, with its two ends connected to the demisting chamber 3 and the manifold chamber 4, respectively. Gas flows inside the tubes, while the outside is the cooling medium in the shell-side space. Its main function is to condense water vapor in the gas into liquid water through heat exchange, thereby removing moisture from the gas and reducing its humidity. The condenser tube assembly 21 consists of multiple condenser tubes and is made of corrosion-resistant materials such as 316L stainless steel. This allows it to withstand potentially corrosive components in the gas, extending its service life and solving the problem of shortened lifespan due to corrosion in existing equipment.

[0034] The structural design of the condenser tube assembly 21 takes heat exchange efficiency into account. By rationally arranging the number, arrangement, and diameter of the condenser tubes, the contact area between the gas and the cooling medium is increased, thereby improving heat exchange efficiency. Simultaneously, the condenser tube assembly 21 or the horizontal shell 1 is inclined relative to the ground, utilizing gravity to allow the condensate generated inside the condenser tubes to flow smoothly to the manifold chamber 4 and be discharged through the second drain pipe 14. This prevents condensate from accumulating inside the tubes and affecting the heat exchange effect, ensuring the continuous and efficient condensation process. The inclined arrangement also facilitates the discharge of wastewater during cleaning, improving the cleaning effect.

[0035] The first demister 31 is installed inside the demister chamber 3 and serves as the first demister barrier after the gas enters the equipment. Its main function is to intercept mist, droplets, and larger particulate impurities in the gas. The first demister 31 can be a baffle demister, a wire mesh demister, a centrifugal demister, etc. When the gas flows through the first demister 31, the droplets and impurities in the gas are impacted and intercepted under the action of inertial force and centrifugal force, thereby achieving preliminary demistering and purification.

[0036] The demisting direction of the first demister 31 is parallel or perpendicular to the flow direction of the medium inside the condenser tube assembly 21. This can be understood as the gas inlet 11 being located at the end or side wall of the horizontal shell. This design optimizes the airflow path according to the gas velocity and demisting requirements, improving demisting efficiency. The high-efficiency demisting capability reduces the amount of mist and impurities entering the condenser tube assembly 21, lowering the risk of blockage and ensuring the heat exchange efficiency of the condenser tube assembly 21. Simultaneously, the structural design of the first demister 31 allows for higher gas flow velocities, reducing the overall size of the equipment while maintaining demisting effectiveness, further saving floor space.

[0037] Gas inlet 11 is located on one side of the demister chamber 3 of the horizontal shell 1. It serves as the channel for external saturated humid gas to enter the equipment, and its main function is to guide the gas into the demister chamber 3 for treatment. The diameter and shape of gas inlet 11 are designed according to the gas flow rate to ensure that the gas enters the chamber at a suitable flow rate, avoiding excessive flow rate that would overload the demister or excessive flow rate that would affect the treatment efficiency.

[0038] Gas outlet 12 is located on one side of the manifold chamber 4 of the horizontal housing 1. It serves as the channel for the gas to exit the equipment after demisting and condensation treatment. Its main function is to deliver the purified gas to the subsequent vacuum pump or other equipment. The design of gas outlet 12 matches gas inlet 11 to ensure the flow balance of gas within the equipment and avoid pressure fluctuations that could affect the treatment effect.

[0039] Both the cooling medium inlet 15 and the cooling medium outlet 16 are located on the horizontal shell 1 and are connected to the shell side formed between the shell and the condenser tube assembly 21, together constituting a circulation channel for the cooling medium. The function of the cooling medium inlet 15 is to introduce the low-temperature cooling medium from the external cooling system into the shell side space. The cooling medium flows around the condenser tube assembly 21 within the shell side, absorbing heat from the gas inside the condenser tubes through heat exchange, causing the water vapor in the gas to condense. The cooling medium outlet 16 discharges the high-temperature cooling medium after heat exchange, returning it to the external cooling system for cooling, thus realizing the recycling of the cooling medium.

[0040] This circulating design ensures the continuous cooling capacity required for the condensation process. By controlling the flow rate and temperature of the cooling medium, the condensation efficiency can be flexibly adjusted to adapt to the gas handling needs under different operating conditions. Simultaneously, the recycling of the cooling medium reduces its consumption, lowers operating costs, and meets energy conservation and environmental protection requirements. Compared to the original two independent cooling systems, the integrated cooling medium channel reduces pipe connections, lowers leakage risk, and reduces resistance loss.

[0041] The first drain pipe 13 is located at the bottom of the demister chamber 3 of the horizontal housing 1. Its main function is to discharge the liquid intercepted by the first demister 31, including mist condensate, impurity mixture, and wastewater generated during backwashing by the backwashing mechanism 5. The first drain pipe 13 is connected to external pipelines to ensure that the discharged liquid can be smoothly transported to the wastewater treatment system or recycling device, and to avoid accumulation in the demister chamber 3.

[0042] Timely drainage of liquids and impurities prevents liquid accumulation in the demisting chamber 3 from affecting gas flow and demisting effect, while also avoiding impurities from depositing in the chamber and causing bacterial growth or equipment corrosion. Compared with the original equipment where the demisting device has a separate drainage pipe, the first drainage pipe 13 in this solution is integrated into the shell, reducing the number of external pipes and lowering the complexity of pipe layout and maintenance costs.

[0043] The second drain pipe 14 is located at the bottom of the manifold 4 of the horizontal shell 1. Its main function is to drain the condensate generated by the condenser tube assembly 21 during the condensation process, as well as the liquid intercepted by the second demister 32 in the manifold 4. The second drain pipe 14 is connected to the external pipeline to discharge the condensate from the equipment in a timely manner, preventing the condensate from accumulating in the manifold 4 or flowing back into the condenser tube assembly 21 and affecting the heat exchange efficiency.

[0044] The smooth drainage of condensate ensures the continuous operation of the condensation process and reduces the risk of corrosion to internal components. The second drain pipe 14 drains independently from the first drain pipe 13, allowing for separate treatment based on the properties of different liquid sources, thus improving the targeting and efficiency of wastewater treatment. Compared to the original equipment where the condensation unit had a separate drain pipe, the integrated second drain pipe 14 further reduces external piping and simplifies the equipment system.

[0045] The backwashing mechanism 5 is located inside the demister chamber 3, and its rinsing direction is the same as that of the first demister 31. Its main function is to periodically clean the first demister 31, removing impurities and dirt adhering to its surface, preventing clogging, and ensuring its demister efficiency. After the equipment has been running for a period of time, impurities may accumulate on the surface of the first demister 31, leading to a decrease in demister efficiency and an increase in gas resistance. At this time, the backwashing mechanism 5 is activated, using high-pressure water or other rinsing media to rinse the demister, flushing off the impurities and discharging them through the first drain pipe 13.

[0046] The backwashing mechanism 5 solves the problem of difficult cleaning of the original demister, enabling online cleaning without disassembling the demister, greatly shortening maintenance time and reducing labor costs. The design of the flushing direction being the same as the demister direction allows the flushing medium to flow along the demister's deflection path, improving cleaning efficiency and ensuring the demister surface remains clean. Regular backwashing can extend the service life of the first demister 31, ensuring long-term stable operation of the equipment.

[0047] The second demister 32 is located in the manifold chamber 4 and is a secondary demister for gas treatment. Its main function is to further remove trace amounts of mist and droplets remaining in the gas after condensation by the condenser tube assembly 21, ensuring that the gas discharged from the gas outlet 12 achieves higher dryness and cleanliness. The gas after condensation may still contain a small amount of incompletely condensed fine droplets. The second demister 32 is also equipped with a backwashing mechanism 5.

[0048] The inclusion of a second demister 32 improves the overall demisting efficiency of the equipment, providing better intake conditions for subsequent vacuum pumps or other equipment, further extending the service life of these devices and reducing the failure rate. This secondary demisting design reflects the refinement and reliability of the equipment structure, ensuring a stable output of clean gas under various operating conditions.

[0049] The flow equalization plate 6 is installed inside the horizontal housing 1, typically located between the gas inlet 11 and the first demister 31 or at the inlet end of the condenser tube assembly 21. Its main function is to guide the airflow, ensuring a uniform gas velocity distribution as it enters the demister chamber 3 or condenser chamber 2. After entering through the gas inlet 11, the gas may experience localized high-speed or vortex regions due to the inlet structure, leading to uneven contact between the gas and the first demister 31 or condenser tube assembly 21, thus affecting the demister and condensation effects. The flow equalization plate 6, through a reasonable opening design or flow guiding structure, rectifyes and distributes the airflow, ensuring a uniform flow of gas through subsequent processing components.

[0050] The flow equalization plate 6 avoids the problems of decreased demisting efficiency or excessive local load on the condenser tube assembly 21 caused by excessively high local flow velocities, thus improving the overall processing efficiency and stability of the equipment. At the same time, the uniform airflow distribution reduces resistance losses during gas flow, lowers energy consumption, and makes the equipment more energy-efficient and effective.

[0051] Work process:

[0052] The saturated humid gas to be treated first enters the demister chamber 3 through the gas inlet 11 on the horizontal shell 1. Before entering the core demister area, the gas flows through the flow equalization plate 6. The flow equalization plate 6 rectifyes and distributes the airflow through a reasonable opening design or flow guiding structure, so that the gas velocity distribution is uniform, avoiding poor subsequent treatment effect due to local high speed or eddies, and ensuring that the gas can flow smoothly and evenly to the first demister 31.

[0053] Upon entering the demisting chamber 3, the gas first comes into contact with the first demister 31. As the gas flows through the first demister 31, the mist, droplets, and larger particulate impurities in the gas are effectively intercepted on the surface under the action of inertial force and centrifugal force. These intercepted liquids, along with the impurities, flow downwards under the action of gravity, collect at the bottom of the demisting chamber 3, and are finally discharged from the equipment through the first drain pipe 13 installed on the horizontal shell 1, preventing accumulation in the chamber and affecting the demisting effect.

[0054] After initial demisting and purification by the first demister 31, the gas continues to flow into the condenser tube assembly 21 within the condenser chamber 2. The condenser tube assembly 21 consists of multiple condenser tubes, with its two ends connected to the demisting chamber 3 and the manifold chamber 4, respectively, allowing the gas to flow within them. Simultaneously, the low-temperature cooling medium from the external cooling system enters the shell-side space formed between the horizontal shell 1 and the condenser tube assembly 21 through the cooling medium inlet 15, circulating around the condenser tube assembly 21 within the shell side. During this process, the gas inside the condenser tubes exchanges heat with the cooling medium outside the tubes, causing water vapor in the gas to condense into liquid water due to heat absorption, achieving further dehydration. The high-temperature cooling medium, after heat exchange, flows back to the external cooling system through the cooling medium outlet 16 for cooling and recycling.

[0055] Because the condenser tube assembly 21 or the horizontal shell 1 is inclined relative to the ground, the condensate generated in the condenser tubes flows towards the manifold chamber 4 under the influence of gravity. After the gas undergoes condensation in the condenser tube assembly 21, it enters the manifold chamber 4. A second demister 32 is installed in the manifold chamber 4. Any trace amounts of mist and droplets that may remain in the condensed gas are intercepted again as the gas flows through the second demister 32, achieving deep demisting and purification, and ensuring the dryness and cleanliness of the gas.

[0056] The liquid intercepted by the second demister 32 and the condensate flowing from the condenser tube group 21 into the manifold chamber 4 are collected at the bottom of the manifold chamber 4 under the action of gravity and discharged from the equipment through the second drain pipe 14 set on the horizontal shell 1, to prevent the accumulated liquid from flowing back and affecting the condensation effect or entering the subsequent equipment.

[0057] After initial demisting in the demisting chamber 3, condensation and dehydration in the condensation chamber 2, and deep demisting in the manifold chamber 4, the clean and dry gas flows smoothly in the manifold chamber 4 and is finally discharged through the gas outlet 12 on the horizontal shell 1, and enters the subsequent vacuum pump or other equipment.

[0058] When the equipment has been running for a period of time, and the surface of the first demister 31 may become clogged due to the interception of impurities, the backwashing mechanism 5 in the demister chamber 3 is activated. The backwashing mechanism 5 washes in the same direction as the demister 31, using high-pressure water or other washing media to clean the first demister 31, washing away impurities and dirt adhering to its surface. The wastewater generated during washing is discharged through the first drain pipe 13, ensuring the demister 31's demister efficiency and service life. The entire process achieves efficient demistering and condensation treatment of saturated humid gas, and the equipment has a high degree of integration, stable and reliable operation, and convenient maintenance.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
