Abstract
Description
Technical Field
[0001] This utility model relates to the field of redistributor technology, specifically a liquid collection and redistributor. Background Technology
[0002] The collector and redistributor is a core component in packed towers that combines liquid collection and redistribution functions. It can overcome the scale-up effect of packed towers in industrial applications, especially large towers, prevent liquid from flowing out of the tower, and remix and combine the liquid after a section of gas-liquid separation in the packing, and then distribute it to the lower packing for further separation.
[0003] In the prior art, Chinese Patent Publication No. CN222240308U discloses an inclined plate type liquid collection and redistributor. By setting up multiple distribution towers, it can effectively avoid the influence of impurities in the liquid on the distribution of leakage, avoid clogging of the leakage hole, and ensure uniform distribution of leakage by dynamically balancing the liquid volume through the distribution towers during the leakage process due to the static level of the liquid surface.
[0004] However, in the existing technology, due to the centralized setting of the distribution tower, the liquid dripping onto the baffle plate is very likely to enter the riser pipe when splashing occurs. After entering the riser pipe, the liquid does not participate in the gas-liquid mass transfer of the lower packing, which leads to further deterioration of the liquid distribution in the tower and a reduction in mass transfer efficiency.
[0005] To address the problems mentioned in the background, those skilled in the art have proposed a liquid collection and redistribution device. Utility Model Content
[0006] The purpose of this invention is to provide a liquid collection and redistribution device to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A liquid collection and redistributor includes a redistributor body and a liquid collection hood installed on the top of the redistributor body. The bottom of the redistributor body is provided with a base plate, and a plurality of elongated distribution towers are installed on the base plate at intervals. The length of the distribution towers gradually decreases from the middle to both sides. A plurality of mounting plates are provided inside the distribution towers, and brackets are installed on the mounting plates. A liquid baffle is installed on the top of the brackets. The liquid baffle is V-shaped, and downward-sloping baffles are installed at both ends of the liquid baffle. Limiting plates are installed on both sides of the top of the distribution towers. A gas guiding channel is formed between the limiting plates, the liquid baffle, and the baffles.
[0009] As a further embodiment of this utility model: a connecting cavity is provided inside the distribution tower, and several connecting holes are provided at intervals on both sides of the top of the distribution tower, and several liquid distribution holes are provided at intervals on the bottom plate and connected to the connecting cavity.
[0010] As a further improvement of this utility model: several air risers penetrating the bottom plate are installed on both sides of the inner wall of the communicating cavity.
[0011] As a further improvement of this utility model, the height of the riser pipe is higher than the height of the connecting hole.
[0012] As a further embodiment of this utility model: the base plate is provided with a plurality of through holes arranged in a ring, the bottom of the redistributor body is provided with a plurality of mounting holes corresponding to the through holes, a sealing ring is installed on the base plate, and a sealing groove that cooperates with the sealing ring is provided at the bottom of the redistributor body.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model collects and gathers the incoming liquid through a liquid collection hood and a redistributor body. When the liquid level in the redistributor body reaches the connecting hole, the liquid can enter the connecting cavity of the distribution tower through the connecting hole, and then achieve uniform distribution of the liquid through the liquid distribution holes on the bottom plate. At the same time, the gas below the bottom plate can enter the interior of the redistributor body above the bottom plate through the riser pipe. The liquid baffle disperses the gas to both sides, so that the gas can mix with the dripping liquid. Furthermore, due to the setting of the baffle and the limiting plate, and the gas guiding channel formed by the liquid baffle, the gas at the top of the riser pipe can be discharged along the gas guiding channel. Moreover, due to the limiting plate and the downward-sloping baffle, the liquid dripping onto the liquid baffle can be prevented from entering the riser pipe when splashing, thereby ensuring the effect of liquid distribution.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] Please see Figures 1-5 A liquid collection and redistributor includes a redistributor body 1 and a liquid collection hood 2 installed on the top of the redistributor body 1. The bottom of the redistributor body 1 is provided with a base plate 3, and a plurality of elongated distribution towers 4 are installed on the base plate 3 at intervals. The length of the plurality of distribution towers 4 gradually decreases from the middle to both sides. A plurality of mounting plates 9 are provided inside the distribution towers 4. A bracket 10 is installed on the mounting plate 9. A liquid baffle 11 is installed on the top of the bracket 10. The liquid baffle 11 is V-shaped, and the two ends of the liquid baffle 11 are equipped with downwardly angled baffles 12. Limiting plates 13 are installed on both sides of the top of the distribution towers 4. A gas guiding channel 14 is formed between the limiting plates 13, the liquid baffle 11, and the baffles 12 for guiding gas.
[0022] In one embodiment, the distribution tower 4 has a communicating cavity 5, and the top two sides of the distribution tower 4 have a plurality of spaced communicating holes 6, and the bottom plate 3 has a plurality of spaced dispensing holes 8 that communicate with the communicating cavity 5.
[0023] The incoming liquid is collected and gathered by the liquid collection hood 2 and the redistributor body 1. When the liquid level in the redistributor body 1 reaches the connecting hole 6, the liquid can enter the connecting cavity 5 of the distribution tower 4 through the connecting hole 6, and then achieve uniform distribution of the liquid through the liquid distribution hole 8 on the bottom plate 3.
[0024] In one embodiment, several air risers 7 penetrating the bottom plate 3 are installed on both sides of the inner wall of the connecting cavity 5.
[0025] The gas below the base plate 3 can enter the redistributor body 1 above the base plate 3 through the riser pipe 7, and the gas is dispersed to both sides by the liquid baffle 11 so that the gas can mix with the dripping liquid.
[0026] In one embodiment, the height of the riser pipe 7 is higher than the height of the connecting hole 6.
[0027] Since the height of the riser pipe 7 is higher than the height of the connecting hole 6, the liquid entering the connecting cavity 5 will not enter the riser pipe 7, thus preventing the liquid from entering the bottom plate 3 from the riser pipe 7 without being distributed.
[0028] Due to the setting of baffle 12 and limiting plate 13, and the gas guiding channel 14 formed by the liquid baffle 11, the gas at the top of the riser pipe 7 can be discharged along the gas guiding channel 14. Furthermore, due to the limiting plate 13 and the downward-sloping baffle 12, liquid dripping onto the liquid baffle 11 can be prevented from entering the riser pipe 7 when splashing occurs, thereby ensuring the effect of liquid distribution. The gas guiding channel 14 is positioned at the baffle 12 and is set downward-slopingly, which can prevent dripping liquid from entering the gas guiding channel 14.
[0029] In one embodiment, the base plate 3 has a plurality of through holes 15 arranged in a ring, the bottom of the redistributor body 1 has a plurality of mounting holes 16 corresponding to the through holes 15, a sealing ring 18 is installed on the base plate 3, and a sealing groove 17 that cooperates with the sealing ring 18 is provided at the bottom of the redistributor body 1.
[0030] To facilitate disassembly and maintenance of this device, during installation, the several through holes 15 on the base plate 3 are aligned with the several mounting holes 16 on the bottom of the redistributor body 1, and the sealing ring 18 on the base plate 3 is inserted into the sealing groove 17 on the bottom of the redistributor body 1 to achieve a sealed connection between the base plate 3 and the redistributor body 1. Then, the installation is completed by inserting bolts into the through holes 15 and screwing them into the threaded mounting holes 16. The bolts can be removed during disassembly.
[0031] This invention collects and gathers the incoming liquid using a liquid collection hood 2 and a redistributor body 1. When the liquid level in the redistributor body 1 reaches the connecting hole 6, the liquid can enter the connecting cavity 5 of the distribution tower 4 through the connecting hole 6, and then achieve uniform distribution of the liquid through the liquid distribution hole 8 on the bottom plate 3. At the same time, the gas below the bottom plate 3 can enter the interior of the redistributor body 1 above the bottom plate 3 through the riser pipe 7. The gas is dispersed to both sides by the liquid baffle 11, so that the gas can mix with the dripping liquid. Due to the setting of the baffle 12 and the limiting plate 13, and the gas guiding channel 14 formed by the liquid baffle 11, the gas at the top of the riser pipe 7 can be discharged along the gas guiding channel 14. Furthermore, due to the limiting plate 13 and the downward-sloping baffle 12, the liquid dripping onto the liquid baffle 11 can be prevented from entering the riser pipe 7 when splashing, thereby ensuring the effect of liquid distribution.
