Description

Technical Field

[0001] This utility model relates to the field of tower tray technology, and in particular to a high-efficiency tower tray gas-liquid contact structure. Background Technology

[0002] In many industrial fields such as chemical, petroleum, and pharmaceutical, distillation columns are key equipment for separating mixtures. The performance of the tray, as a core internal component of the distillation column, directly affects the efficiency and energy consumption of the distillation process. The main function of the tray is to provide sufficient contact opportunities between the gas and liquid phases, enabling the separation of light components in the gas phase and heavy components in the liquid phase during mass and heat transfer. Traditional gas-liquid contact structures for trays, such as bubble cap trays, sieve trays, and valve trays, have been used in industrial production for many years. Bubble cap trays have advantages such as high operational flexibility and high tray efficiency, but their structure is complex, costly, and has a large gas phase pressure drop. Sieve trays have a simple structure, low cost, and low gas phase pressure drop, but their operational flexibility is relatively small and prone to leakage. Valve trays have good overall performance, with high operational flexibility, high tray efficiency, and low gas phase pressure drop, but during long-term operation, the valves are prone to jamming and wear, affecting the normal operation of the tray and separation efficiency.

[0003] Currently, trays often become clogged during prolonged use, resulting in insufficient gas-liquid contact, hindering mass and heat transfer processes. This prevents effective separation of light and heavy components, increases impurity content in the product, and makes it difficult to achieve the expected purity standards. At the same time, the clog reduces the contact area and contact time between the gas and liquid phases, making it impossible to complete the separation task that could have been completed within the specified time and number of trays. More trays or longer time are required to achieve the same separation effect.

[0004] Therefore, there is an urgent need to provide a high-efficiency tower tray gas-liquid contact structure to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency tower tray gas-liquid contact structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a high-efficiency tower tray gas-liquid contact structure, including two mounting blocks, each mounting block having an L-shaped connector fixedly connected to its inner wall, each L-shaped connector having a connecting plate fixedly connected to its top, each connecting plate having multiple water inlets at its top, each water inlet having a connecting pipe fixedly connected to its top, and each connecting pipe having an anti-clogging component installed on it.

[0007] The present invention is further configured such that the outer walls of the two L-shaped connectors are perpendicular to the outer walls of the corresponding mounting blocks and connecting plates.

[0008] With the above technical solution, during the installation process, workers can easily align the L-shaped connector with the mounting block and connecting plate, ensuring the accuracy and precision of the installation, reducing the adjustment and trial-and-error time during the installation process, and improving installation efficiency.

[0009] The present invention is further configured such that: a fixing plate is fixedly connected to one side of the outer wall of each of the multiple connecting plates; multiple first bolts are threadedly connected to each of the two L-shaped connecting pieces; multiple second bolts are threadedly connected between each pair of fixing plates; a locking nut is threadedly connected to the top of the outer wall of each of the multiple first bolts; and a washer is slidably connected to the outer wall of each of the multiple second bolts.

[0010] The above technical solution involves first assembling the corresponding fixing plates, then threading the first and second bolts into the corresponding parts, and simultaneously threading the corresponding locking nuts onto the outer walls of the first and second bolts to achieve the purpose of fixing.

[0011] The present invention is further configured such that the top and bottom of the plurality of gaskets are tightly fitted with the corresponding fixing plate and the first bolt.

[0012] Through the above technical solution, the gasket can evenly distribute the pressure applied by the bolt head to the surface of the fixing plate. This avoids the problem of local deformation of the fixing plate due to pressure concentration, making the connection between the fixing plates and between the fixing plate and the L-shaped connector more stable and reliable, and ensuring that the entire structure can maintain a good connection state when subjected to external forces.

[0013] The present invention is further configured such that: the anti-blocking component includes multiple fixed rods fixedly connected to the top of the connecting pipe, each set of fixed rods has a threaded rod fixedly connected to the inner wall of each set of fixed rods, a valve cover is threadedly connected to the outer wall of each set of threaded rods, an adjusting bolt is threadedly connected to the top of the outer wall of each set of threaded rods, a rotating rod is rotatably connected to the bottom of each set of threaded rods, and multiple scrapers are fixedly connected to the outer wall of each set of rotating rods.

[0014] Through the above technical solution, the gas and liquid first move upward from the bottom of the connecting plate. When the gas and liquid enter the connecting pipe, they will flush the scraper. Since the scraper has an angle, it rotates under the impact of the gas and liquid. At the same time, the outer walls of multiple scrapers are in close contact with the inner wall of the connecting pipe, so that multiple scrapers can scrape off the dirt on the inner wall of the connecting pipe.

[0015] The present invention is further configured such that the radius of each of the plurality of valve covers is greater than the radius of the connecting pipe, and the bottom of each of the plurality of adjusting bolts fits into the top of the corresponding valve cover.

[0016] With the above technical solution, when the gas-liquid flow rate changes, the position of the valve cover can be adjusted by adjusting the bolts to change the gas-liquid flow area and resistance. When the gas-liquid flow rate is large, the valve cover can be raised appropriately to increase the flow area and reduce the resistance; when the flow rate is small, the valve cover can be lowered to increase the gas-liquid flow rate and contact effect.

[0017] The present invention is further configured such that the outer walls of the plurality of scrapers are fitted with the inner walls of the corresponding water inlets, and the plurality of scrapers are provided with bevels.

[0018] The above technical solution enables the scraper to fit tightly against the inner wall of the inlet during rotation, leaving no space for dirt residue. Whether it is scale, silt or other impurities, they can be effectively scraped off by the scraper, which greatly reduces the probability of blockage at the inlet and ensures that gas and liquid flow smoothly from the inlet into the connecting pipe, maintaining the normal operation of the system.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting a fixing plate, a first bolt, and a second bolt, this utility model allows for easy installation. During installation, each component only needs to be positioned according to the design requirements, and then the fixing plate is connected to the corresponding component with bolts. This standardized connection method reduces the adjustment and calibration work during installation, lowers the installation difficulty, improves installation efficiency, and shortens the equipment installation cycle.

[0021] 2. This utility model, by setting anti-clogging components, can prevent clogging, ensure uniform gas-liquid distribution on the tray, increase the gas-liquid contact area and contact time, thereby improving mass and heat transfer efficiency, enhancing the separation performance of the tray, and at the same time, reducing the wear of components and extending the service life of the tray and related equipment.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] Please see Figure 1 - Figure 5 A high-efficiency tower tray gas-liquid contact structure includes two mounting blocks 1. L-shaped connectors 2 are fixedly connected to the inner walls of both mounting blocks 1. Connecting plates 3 are fixedly connected to the tops of both L-shaped connectors 2. The outer walls of both L-shaped connectors 2 are perpendicular to the corresponding outer walls of the mounting blocks 1 and connecting plates 3. During installation, workers can easily align the L-shaped connectors 2 with the mounting blocks 1 and connecting plates 3, ensuring accuracy and precision, reducing adjustment and trial-and-error time, and improving installation efficiency. Fixing plates 301 are fixedly connected to one side of the outer walls of multiple connecting plates 3. Multiple first bolts 302 are threaded onto both L-shaped connectors 2. Multiple second bolts 303 are threaded between every two fixing plates 301. Locking nuts 304 are threaded to the top of the outer walls of the multiple first bolts 302. Both bolts 303 have slidably connected washers 305 on their outer walls. First, the corresponding fixing plates 301 are spliced ​​together, and then the first bolt 302 and the second bolt 303 are threaded into the corresponding parts. At the same time, the corresponding locking nuts 304 are threaded onto the outer walls of the first bolt 302 and the second bolt 303 to achieve the purpose of fixing. The top and bottom of the multiple washers 305 are tightly fitted with the corresponding fixing plates 301 and the first bolt 302. The washers 305 can evenly distribute the pressure applied by the bolt head to the surface of the fixing plate 301. This avoids the problem of local deformation of the fixing plate 301 due to pressure concentration, making the connection between the fixing plates 301 and between the fixing plates 301 and the L-shaped connector 2 more stable and reliable, ensuring that the entire structure can maintain a good connection state when subjected to external forces.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, multiple connecting plates 3 are provided with multiple water inlets 4 at their tops, and connecting pipes 5 are fixedly connected to the tops of the multiple water inlets 4. Anti-clogging components 6 are installed on the multiple connecting pipes 5. Each anti-clogging component 6 includes multiple fixing rods 601 fixedly connected to the top of the connecting pipes 5. Threaded rods 602 are fixedly connected to the inner walls of each set of fixing rods 601. Valve covers 603 are threadedly connected to the outer walls of the multiple threaded rods 602, and adjusting bolts 604 are threadedly connected to the top of the outer walls of the multiple threaded rods 602. Each threaded rod 602 has a rotating rod 605 rotatably connected to its bottom. Multiple scrapers 606 are fixedly connected to the outer walls of each rotating rod 605. First, the gas and liquid move upwards from the bottom of the connecting plate 3. When the gas and liquid enter the connecting pipe 5, they flush the scrapers 606. Because the scrapers 606 have an angled design, they rotate under the impact of the gas and liquid. Simultaneously, the outer walls of the multiple scrapers 606 are tightly fitted against the inner wall of the connecting pipe 5, thus enabling the multiple scrapers 606 to clean the inner wall of the connecting pipe 5. The system scrapes away dirt. Multiple valve covers 603 have radii larger than the connecting pipe 5, and the bottoms of multiple adjusting bolts 604 engage with the tops of their respective valve covers 603. When the gas-liquid flow rate changes, the position of the valve cover 603 can be adjusted using the adjusting bolts 604 to change the gas-liquid flow area and resistance. When the gas-liquid flow rate is high, the valve cover 603 can be raised to increase the flow area and reduce resistance; when the flow rate is low, the valve cover 603 can be lowered to increase the gas-liquid flow rate and contact effect. The outer walls of multiple scrapers 606 engage with the inner walls of their respective inlets 4, and each scraper 606 is angled. This ensures that the scrapers 606 can tightly adhere to the inner wall of the inlet 4 during rotation, leaving no space for dirt residue. Whether it's scale, silt, or other impurities, they can be effectively scraped away by the scrapers 606, significantly reducing the probability of blockage at the inlet 4 and ensuring smooth gas-liquid flow from the inlet 4 into the connecting pipe 5, maintaining the normal operation of the system.

[0031] In use, the corresponding fixing plates 301 are first spliced ​​together, and then the first bolt 302 and the second bolt 303 are threaded into the corresponding parts. At the same time, the corresponding locking nuts 304 are threaded onto the outer walls of the first bolt 302 and the second bolt 303 to achieve the purpose of fixing. Then, the gas and liquid will move upward from the bottom of the connecting plate 3. When the gas and liquid enter the connecting pipe 5, they will flush the scraper 606. Since the scraper 606 has an angle, it will rotate under the impact of the gas and liquid. At the same time, the outer walls of the multiple scrapers 606 are in close contact with the inner wall of the connecting pipe 5, so that the multiple scrapers 606 can scrape off the dirt on the inner wall of the connecting pipe 5.
