Description

Technical Field

[0001] The invention relates to the field of chemical production equipment, and more specifically to a liquid distributor for a chemical packing tower. Background Art

[0002] In the fields of chemical industry, environmental protection and energy, as an efficient gas-liquid mass transfer and reaction equipment, packed towers are widely used in distillation, absorption, extraction and gas purification processes. The core is to use packing as the basic component for gas-liquid two-phase contact and mass transfer, and to achieve efficient mass and heat transfer through the film flow of liquid on the surface of packing and reverse contact with gas. The performance of packed towers is directly related to the efficiency of gas-liquid contact and the overall production capacity of the system. As an indispensable part of packed towers, the design quality of tower internals determines whether the packed tower can give full play to its effectiveness.

[0003] Among the many tower internals, the liquid distributor is one of the key factors that determine the performance of a packed tower because it directly affects the initial distribution uniformity of the liquid. An ideal liquid distributor should be able to achieve uniform distribution and redistribution of the liquid at the top of the packing or at a specific height, thereby increasing the effective area of ​​mass transfer and heat transfer, optimizing the interphase contact conditions, and thus improving the overall efficiency of the tower. However, existing liquid distributor technology generally faces the problem of uneven distribution in practical applications, which directly limits the room for improvement in the performance of packed towers.

[0004] There are many types of common liquid distributors on the market, including gravity type, pressure type, trough type, disc type and spray type, each type has its specific application scenarios and advantages. In particular, the spray type liquid distributor has been widely used in the field of gas purification due to its simple structure and flexible operation. However, during the spraying process, the dust and impurities accumulated in the water tank can easily clog the nozzle, resulting in uneven spraying or even interruption, seriously affecting the normal operation and purification effect of the equipment. At the same time, the dust and sticky impurities carried in the exhaust gas are also easy to deposit in the packing layer, forming a blockage, further reducing the processing capacity and efficiency of the packing tower.

[0017] Furthermore, a filter net and an adsorption cotton layer for filtering and adsorbing dirt are arranged inside the collection box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This scheme is provided with a two-way flow guide mechanism and a cleaning mechanism, and the cleaning liquid is accurately sprayed into the first water guide groove in the container through the two-way flow guide mechanism. The powerful water flow impact force of the cleaning liquid is used to drive the first water guide groove to rotate clockwise, and drive the rotation of the threaded rod, and further drive the conical cover to slowly descend along the inner wall of the circulation pipe, scraping and removing the dirt and sediment attached to the inner wall. When the conical cover reaches the bottom of the circulation pipe, the cleaning rod is inserted into the spraying port of the spraying pipe for deep dredging. During this operation, not only the uniform distribution of the cleaning liquid in the packing tower is achieved, but also the liquid distribution efficiency is improved. Moreover, through the self-cleaning mechanism, the dirt and sediment on the inner wall of the circulation pipe and the spraying port of the spraying pipe are effectively removed, avoiding the blockage problem caused by the accumulation of dust and impurities, ensuring the continuous and efficient operation of the spraying system, and extending the overall service life of the packing tower.

[0020] (2) This scheme is provided with a combination of a conical cover, a splash plate, a lower water tank and a spray pipe. When the cleaning liquid flows into the circulation pipe from the water collecting tank, part of the liquid naturally penetrates into the gap between the conical cover and the inner wall of the circulation pipe. As the dredging work of the spray pipe progresses, the liquid gradually accumulates in the gap, forming a sufficient immersion environment for the dirt on the inner wall, softening the dirt. At the same time, another part of the cleaning liquid flows into the area surrounded by the conical cover and the splash plate. The liquid is then guided to the bottom of the circulation pipe through the lower water tank and finally sprayed out from the spray port of the spray pipe. In this process, the design of the splash plate not only realizes the spray treatment of the gas inside the packing tower, but also uses the clean liquid to flush the spray port, ensuring the continuous and efficient operation of the spray system.

[0021] (3) This scheme is provided with a first connecting pipe, a first annular pipe, a first nozzle, an L-shaped nozzle and a self-cleaning mechanism, and the first connecting pipe is connected to the output end of the external water supply system to start the supply of the cleaning fluid. The cleaning fluid enters the first annular pipe through the first connecting pipe and is divided into each first nozzle and L-shaped nozzle. The nozzles of the first nozzle and the L-shaped nozzle spray out the cleaning liquid, which acts precisely on the first water guide groove. The water flow driving force of the cleaning liquid is used to cause the threaded rod to rotate clockwise. The rotation of the threaded rod drives the conical cover to slowly descend along the limit rod, scraping off the dirt attached to the inner wall of the circulation pipe. The cleaning rod moving with the conical cover simultaneously clears the spraying port of the spraying pipe. This operation realizes the automatic cleaning and maintenance of the circulation pipe and the spraying pipe without manual intervention, thereby improving the maintenance efficiency and safety.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0038] See also Figures 1 to 8 A liquid distributor for a chemical packing tower comprises a container 1, a dust cover 2 is provided on the top of the container 1, the dust cover 2 is bolted to the container 1, the interior of the container 1 is concave; a circulation mechanism 3 for liquid circulation is provided at the concave part of the container 1, the circulation mechanism 3 comprises water collecting tanks 31 evenly distributed inside the container 1, the bottom of the water collecting tanks 31 are fixedly connected with circulation pipes 32 for liquid circulation, and the circulation pipes 32 penetrate the bottom of the container 1. The flow pipe 32 is fixedly connected with a spray pipe 33; and the spray pipe 33 is used to diffusely spray the liquid, a threaded rod 5 is provided at the center of the flow pipe 32, a guide mechanism 8 is provided at the top of the threaded rod 5, and a cleaning mechanism 9 for cleaning the spray pipe 33 is provided at the middle of the outer circumference of the threaded rod 5. The cleaning mechanism 9 includes a conical cover 92 and a cleaning rod 94 for cleaning the spray port of the spray pipe 33. A two-way guide mechanism 4 for driving the guide mechanism 8 to move is provided inside the pallet 1;

[0039] Among them, the guide mechanism 8 includes a fixed sleeve 81 fixedly connected to the top of the threaded rod 5, the outer cylindrical surface of the fixed sleeve 81 is fixedly connected with a uniformly distributed connecting plate 82, one side of the connecting plate 82 is fixedly connected with a partition 83, and the two sides of the outer surface of the partition 83 are respectively fixedly connected with a first water guide groove 84 and a second water guide groove 85.

[0040] When the gas inside the packing tower is treated, the container 1 is installed on the inner top of the packing tower as the core component of liquid distribution and conduction. By setting a two-way flow guide mechanism 4, the mechanism is connected to the external pumping equipment to be responsible for conveying the clean liquid specially used for treating flue gas into the container 1. In order to prevent external dust from invading, the top of the container 1 is equipped with a dust cover 2 to ensure the cleanliness of the internal environment. When the clean liquid is accurately sprayed to the first water guide groove 84 in the container 1 through the two-way flow guide mechanism 4, its strong water flow impact force not only promotes the uniform distribution of the liquid, but also cleverly drives the first water guide groove 84 to rotate clockwise. This rotation action further drives the fixed sleeve 81 and the threaded rod 5 thereon to rotate clockwise in the circulation pipe 32 through the linkage effect of the partition plate 83 and the connecting plate 82. As the threaded rod 5 rotates, the cleaning mechanism 9 connected thereto begins to play its important role. The conical cover 92 in the cleaning mechanism 9 slowly descends along the inner wall of the circulation pipe 32, and uses the scraping effect of its edge to effectively remove the dirt and sediment attached to the inner wall. When the conical cover 92 reaches the bottom of the circulation pipe 32, the cleaning rod 94 is accurately inserted into the spray port of the spray pipe 33 for deep dredging, ensuring that the spray pipe 33 remains unobstructed after long-term operation, avoiding blockage problems caused by accumulation of dust and impurities. Through the above operation, not only the distribution efficiency of the liquid inside the packing tower is optimized, but also the innovative self-cleaning mechanism ensures the continuous and efficient operation of the spraying system, thereby extending the overall service life of the packing tower and improving its efficiency and stability in treating flue gas.

[0041] like Figure 6 , Figure 7 , Figure 8 As shown, the cleaning mechanism 9 also includes a threaded sleeve 91 threadedly connected to the outer circumferential surface of the threaded rod 5, and a conical cover 92 is fixedly connected to the bottom of the threaded sleeve 91, and the central axis of the conical cover 92 is hollow; and the conical cover 92 is sleeved on the threaded rod 5, and the inner wall of the conical cover 92 is fixedly connected to evenly distributed cleaning rods 94, and a lower water trough 93 is opened inside the conical cover 92; and a splash plate 97 fixedly connected to the conical cover 92 is provided on the outer side of the lower water trough 93.

[0042] When the cleaning liquid flows from the sump 31 into the circulation pipe 32, part of the liquid will naturally penetrate into the gap between the conical cover 92 and the inner wall of the circulation pipe 32. As the dredging work of the spray pipe 33 continues to advance, the cleaning liquid in this area will gradually accumulate, forming a sufficient soaking environment for the dirt on the inner wall. This process effectively softens the dirt, allowing the conical cover 92 to remove the dirt more easily and efficiently in the subsequent scraping operation. At the same time, another part of the cleaning liquid will flow into the area surrounded by the conical cover 92 and the splash plate 97. These liquids will then be guided to the bottom of the circulation pipe 32 through the lower trough 93, and finally sprayed out from the spray port of the spray pipe 33. In this process, the conical cover 92 is divided into two areas by the splash plate 97, which not only realizes the effective spraying treatment of the gas inside the packing tower, but also cleverly uses the cleaning liquid to rinse the spray port that has just completed the dredging operation. This operation ensures that the spray pipe 33 can maintain a better spraying effect in subsequent use, and avoids affecting its performance due to blockage or residue.

[0043] like Figure 6 , Figure 7 , Figure 8 As shown, a limiting hole 98 is provided on the outer surface of the conical cover 92, and a limiting rod 95 is connected to the inside of the limiting hole 98. Both ends of the limiting rod 95 are provided with support plates 96 fixedly connected to the inner wall of the circulation tube 32. The bottom end of the inner wall of the circulation tube 32 is provided with a first support seat 6 for supporting the threaded rod 5, and the top end of the inner wall of the circulation tube 32 is provided with a limiting seat 7 for limiting the threaded rod 5.

[0044] When the water flow impacts the first water guide groove 84 with a strong impact force, causing it to rotate clockwise, and through the exquisite linkage mechanism between the partition plate 83 and the connecting plate 82, the fixed sleeve 81 and the threaded rod 5 carried by it can be driven to rotate clockwise in the circulation pipe 32, and as the threaded rod 5 rotates smoothly, the threaded sleeve 91 thereon is guided precisely by the limiting rod 95, and the conical cover 92 begins to slide down slowly along the limiting rod 95. In this process, the conical cover 92, as a cleaning tool, is firmly pulled by the threaded sleeve 91 and closely adheres to the inner wall of the circulation pipe 32 for deep cleaning. In this process, the coordinated work of the limiting rod 95 and the threaded rod 5 provides a solid stability guarantee for the cleaning operation of the conical cover 92, and the two together constitute a stable motion frame, ensuring that the conical cover 92 always remains stable and vibration-free during the process of scraping the inner wall of the circulation pipe 32 up and down, thereby improving the cleaning efficiency and safety.

[0045] like Figure 1 , Figure 3 , Figure 4As shown, the two-way flow guide mechanism 4 includes a first annular tube 41 fixedly connected to the inner wall of the container 1, and the outer circumferential surface of the first annular tube 41 is fixedly connected to a first nozzle 42 that is evenly distributed; and the first nozzle 42 passes through the water collecting trough 31 and is aligned with the depression of the first water guide groove 84, and one side of the outer circumferential surface of the first annular tube 41 is fixedly connected to an L-shaped nozzle 43 for guiding the first water guide groove 84 at the center position, and the other side of the outer circumferential surface of the first annular tube 41 is fixedly connected to a first connecting tube 44.

[0046] When cleaning and maintaining the circulation pipe 32 and the spray pipe 33, the first connecting pipe 44 needs to be connected to the output end of the external water supply system, so that the cleaning fluid can enter the first annular pipe 41 through the first connecting pipe 44, and then be divided into each first spray pipe 42 and L-shaped spray pipe 43, and the cleaning liquid sprayed by the nozzle of the first spray pipe 42 and L-shaped spray pipe 43 accurately acts on the first water guide groove 84, and the driving force of the water flow causes the threaded rod 5 to rotate clockwise. This rotation action drives the conical cover 92 to slowly descend along the limit rod 95, effectively scraping off the dirt attached to the inner wall of the circulation pipe 32. At the same time, the cleaning rod 94 moving with the conical cover 92 will also dredge the spray port of the spray pipe 33 to ensure that there is no blockage.

[0047] like Figure 1 , Figure 3 , Figure 4 As shown, the two-way flow guide mechanism 4 also includes a second annular tube 45 arranged in the middle of the interior of the container 1, and the outer cylindrical surface of the second annular tube 45 is fixedly connected to a uniformly distributed second nozzle 46; and the second nozzle 46 passes through the water collecting groove 31 and is aligned with the depression of the second water guide groove 85, and the inner side of the outer cylindrical surface of the second annular tube 45 is provided with a third nozzle 47 for guiding the second water guide groove 85 at the center position, and the top end of the outer cylindrical surface of the second annular tube 45 is fixedly connected to the second connecting tube 48, and the outer interface ends of the first connecting tube 44 and the second connecting tube 48 both pass through the container 1.

[0048] like Figure 1 , Figure 3 , Figure 4 As shown, the first water guide groove 84 and the second water guide groove 85 have the same shape and function, but are oriented in opposite directions, and the inner bottoms of the first water guide groove 84 and the second water guide groove 85 are both provided with evenly distributed leakage holes.

[0049] like Figure 6 , Figure 7 As shown, the first water guide groove 84 and the second water guide groove 85 are both in the shape of a half-cut cylinder, and the inner walls are coated with anti-corrosion materials.

[0050] If the inner wall of the circulation pipe 32 needs to be scraped up and down more thoroughly, the control valve of the first connecting pipe 44 can be closed, and the second connecting pipe 48 can be connected to the other output end of the water supply system, and its control valve can be opened. At this time, the cleaning fluid enters the second annular pipe 45 through the second connecting pipe 48, and is then distributed to each second nozzle 46 and the third nozzle 47. The cleaning liquid sprayed from these nozzles impacts the second water guide groove 85, and uses strong water force to force the threaded rod 5 to rotate counterclockwise. This reverse rotation causes the conical cover 92 to rise along the limit rod 95, realizing the back-and-forth scraping operation of the dirt on the inner wall of the circulation pipe 32. During the rising process of the conical cover 92, the cleaning rod 94 will be automatically drawn out from the spray port of the spray pipe 33 to ensure that the liquid that subsequently enters the circulation pipe 32 can be smoothly sprayed out from the spray port, and continue to perform the gas spray purification task in the packing tower. During the above operation, no matter whether the first water gutter 84 or the second water gutter 85 rotates clockwise or counterclockwise during the cleaning process, since the bottom is designed with evenly distributed leakage holes and the inner wall is covered with anti-corrosion material, the cleaning liquid can be discharged smoothly, effectively avoiding internal corrosion problems caused by liquid accumulation, and ensuring the long-term stable operation of the equipment.

[0051] like Figure 7 As shown, the outer edge of the conical cover 92 conflicts with the inner wall of the flow tube 32, and the outer diameter of the cleaning rod 94 is adapted to the spraying port of the spraying tube 33.

[0052] like Figure 2 , Figure 7 As shown, the outer wall of the circulation tube 32 is provided with a collecting slot 36, and the outer cylindrical surface of the circulation tube 32 located on one side of the collecting slot 36 is fixedly connected with a collecting box 34 for collecting dirt. The outer fixed sleeve of the collecting box 34 is provided with a sealing cover 35, and the bottom of the collecting box 34 is provided with evenly distributed water leakage holes.

[0053] like Figure 7 As shown, the interior of the collecting box 34 is provided with a filter net and an adsorbent cotton layer for filtering and adsorbing dirt.

[0054] In the process of cleaning the inner wall of the circulation tube 32, the dirt on the tube wall is effectively removed by scraping up and down with the conical cover 92. However, if the scraped dirt is directly discharged through the spray pipe 33, the problem of impurity accumulation in the packing tower may be aggravated. At this time, the strong impact force of the water flow can be used to not only drive the conical cover 92 to move upward to continue the cleaning operation, but also the dirt and impurity liquid scraped off in this process are guided to the collection slot 36, and then flow into the collection box 34, and the collection box 34 is equipped with a filter screen and an adsorption cotton layer inside to perform deep filtration and adsorption treatment on the incoming liquid. The filter screen initially intercepts larger particles of impurities, and the adsorption cotton layer further adsorbs tiny particles and pollutants with poor solubility, ensuring that only the fully purified clean liquid can be smoothly discharged through the leaking hole at the bottom, thereby avoiding the impurities from flowing back into the packing tower and maintaining the cleanliness and efficient operation of the system.

[0055] Instructions for use: During the gas treatment process inside the packed tower, the container 1 is installed on the inner top of the packed tower, connected to the external pumping equipment through the two-way flow guide mechanism 4, and the clean liquid is transported to the container 1 for treating the flue gas. The top of the container 1 is equipped with a dust cover 2 to prevent external dust from invading and ensure the cleanliness of the internal environment. The clean liquid is accurately sprayed into the first water guide groove 84 in the container 1 through the two-way flow guide mechanism 4. The strong impact force of the water flow not only promotes the uniform distribution of the liquid, but also drives the first water guide groove 84 to rotate clockwise. The rotation of the first water guide groove 84 drives the fixed sleeve 81 and the threaded rod 5 thereon to rotate clockwise in the circulation pipe 32 through the linkage effect of the partition plate 83 and the connecting plate 82. As the threaded rod 5 rotates, the conical cover 92 in the cleaning mechanism 9 slowly descends along the inner wall of the circulation pipe 32 under the guidance of the threaded sleeve 91 and the limit rod 95 to scrape off dirt and sediment. When the conical cover 92 reaches the bottom, the cleaning rod 94 is inserted into the spraying port of the spraying pipe 33 to perform deep dredging to ensure that the spraying pipe 33 is unobstructed. Part of the cleaning liquid penetrates between the conical cover 92 and the inner wall of the circulation pipe 32, softens the dirt, and is scraped off as the conical cover 92 moves. Another part of the cleaning liquid flows into the area surrounded by the conical cover 92 and the splash plate 97, is guided to the bottom of the circulation pipe 32 through the lower water tank 93, and is sprayed out by the spraying pipe 33, so as to achieve spraying treatment and flush the spraying port at the same time. When the first connecting pipe 44 is connected to the water supply system, the cleaning liquid acts on the first water guide groove 84 through the first annular pipe 41, the first spray pipe 42 and the L-shaped spray pipe 43, driving it to rotate clockwise, driving the conical cover 92 to descend and scrape the inner wall of the circulation pipe 32. If more thorough cleaning is required, close the first connecting pipe 44 and connect the second connecting pipe 48 to the water supply system. The cleaning liquid impacts the second water guide groove 85 through the second annular tube 45, the second nozzle 46 and the third nozzle 47, forcing the threaded rod 5 to rotate counterclockwise, and the conical cover 92 rises along the limit rod 95 to achieve reciprocating scraping cleaning. The scraped dirt and impurity liquid are guided to the collection slot 36, and after flowing into the collection box 34, the liquid is deeply filtered and adsorbed by the filter screen and the adsorption cotton layer, so that the purified cleaning liquid is discharged through the water leakage hole to prevent impurities from flowing back into the packing tower.

[0056] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
