Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of separation devices, and in particular to a chemical packed tower separation device. Background Technology
[0002] Packed towers, as one of the most important gas-liquid mass transfer devices in chemical production, have been widely used in processes such as waste gas treatment, wastewater purification, gas absorption, distillation, and extraction.
[0003] The basic structure of a packed tower includes components such as the tower body, packing layer, liquid distributor, and supporting structure. Its working principle is that liquid is evenly sprayed from the top of the tower onto the surface of the packing through the distributor, flowing downwards, while gas enters from the bottom of the tower and flows upwards against the current through the voids in the packing layer, contacting the liquid to achieve mass transfer.
[0004] The liquid distributor is responsible for evenly distributing the liquid on the packing surface to ensure sufficient contact between the gas and liquid phases in the packing layer. However, the interior of the existing liquid distributor is difficult to clean, which leads to pore blockage and makes it difficult to evenly spray the liquid on the packing surface, thereby reducing the contact efficiency between the gas and liquid phases. Utility Model Content
[0005] The purpose of this invention is to provide a chemical packing tower separation device to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is:
[0007] A chemical packed tower separation device includes a packed tower body, an air inlet fixedly connected to one side of the packed tower body, a drain outlet fixedly connected to one side of the packed tower body, a water supply pipe fixedly connected to the top of the packed tower body, a four-way pipe at the bottom of the water supply pipe, a connecting pipe fixedly connected to one end of the four-way pipe, a snap-fit block fixedly connected to the bottom of the connecting pipe, a top plate movably connected to the surface of the snap-fit block, a liquid equalization tank at the bottom of the top plate, a distribution groove inside the liquid equalization tank, partition plates on both sides of the distribution groove, the side of the partition plate away from the distribution groove being in contact with the liquid equalization tank, and a first water inlet at the bottom of the liquid equalization tank.
[0008] In some embodiments, the liquid equalization tank is provided with a T-shaped groove inside, and a T-shaped block is slidably connected inside the T-shaped groove, the T-shaped block and the T-shaped groove being adapted to each other.
[0009] In some embodiments, the top of the equalization tank is provided with a mounting groove, a top plate is slidably connected inside the mounting groove, and a waterproof ring is fixedly connected to the surface of the top plate.
[0010] In some embodiments, a top plate is movably connected to the surface of the snap-fit block, a diverter cylinder is fixedly connected to the bottom of the snap-fit block, and a first drainage hole is fixedly connected to the bottom of the diverter cylinder.
[0011] In some embodiments, the surface of the partition plate is provided with a second water inlet.
[0012] In some embodiments, a plurality of second drainage holes are uniformly formed at the bottom of the distribution groove, and the diameter of the second drainage holes is smaller than that of the first drainage holes.
[0013] In some embodiments, both the top plate and the surface of the liquid equalization tank are provided with mounting ports, and the mounting ports are internally threaded with fixing bolts.
[0014] In some embodiments, the distribution trough is made of polypropylene composite material.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) When the chemical raw material gas enters the main body of the packed tower through the inlet, the liquid transported by the water supply pipe flows sequentially through the water supply pipe, the four-way pipe, the connecting pipe, the clamping block to the distribution cylinder for preliminary distribution, and then falls into the liquid equalization tank through the first drop hole. The partition plate inside the liquid equalization tank divides the tank into multiple chambers, making the liquid distribution more uniform, avoiding large local flow differences, and ensuring that the liquid flows out from the second water outlet in a uniform state, so as to fully and effectively contact and separate with the gas in the packed tower, thereby improving the efficiency and quality of chemical separation.
[0017] (2) The partition plate inside the equalization tank is detachably connected to the tank body. When it is necessary to clean, maintain or replace the partition plate inside the equalization tank, it can be easily removed without complicated operating procedures, which greatly improves the ease of use and maintenance efficiency of the device and reduces maintenance costs and time.

Therefore, they should not be construed as limitations on this utility model.
[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] In the current technology, the liquid distributor is responsible for uniformly distributing the liquid on the surface of the packing material to ensure sufficient contact between the gas and liquid phases in the packing layer. However, the interior of the existing liquid distributor is difficult to clean, which leads to pore blockage and makes it difficult to spray the liquid evenly on the surface of the packing material, thereby reducing the contact efficiency between the gas and liquid phases.
[0028] like Figures 1-5As shown, this utility model embodiment provides a chemical packed tower separation device, including a packed tower body 1, an air inlet 101 fixedly connected to one side of the packed tower body 1, a drain outlet 102 fixedly connected to one side of the packed tower body 1, a water supply pipe 2 fixedly connected to the top of the packed tower body 1, a four-way pipe 201 at the bottom of the water supply pipe 2, a connecting pipe 202 fixedly connected to one end of the four-way pipe 201, a snap-fit block 203 fixedly connected to the bottom of the connecting pipe 202, a top plate 3 movably connected to the surface of the snap-fit block 203, a liquid equalization tank 302 provided at the bottom of the top plate 3, a distribution groove 4 provided inside the liquid equalization tank 302, partition plates 404 on both sides of the distribution groove 4, the side of the partition plate 404 away from the distribution groove 4 being in contact with the liquid equalization tank 302, and a first water inlet 403 opened at the bottom of the liquid equalization tank 302.
[0029] Chemical raw material gas enters the packed tower body 1 through inlet 101, while water supply pipe 2 delivers liquid into the tower through external water supply equipment. The liquid flows from water supply pipe 2 into four-way pipe 201, then through connecting pipe 202 and clamping block 203 to reach distribution cylinder 204. Initial distribution is completed in distribution cylinder 204, and the liquid falls into equalization tank 302 through first drainage hole 205. Divider plate 404 in equalization tank 302 divides it into multiple chambers, ensuring that the liquid flows out evenly from the first water outlet 403. This design allows for a more uniform distribution of liquid within equalization tank 302, avoiding excessive localized differences in liquid flow, and thus ensuring that the liquid flows out more evenly from the second drainage hole 306. The gas flows out and enters from the inlet 101, allowing for more thorough and efficient gas-liquid contact and separation within the packed tower body 1, thus improving the efficiency and quality of chemical separation. The partition plate 404 is installed inside the liquid equalization tank 302. This design not only helps to ensure the uniform distribution of liquid within the liquid equalization tank 302, but also allows for a detachable connection between the partition plate 404 and the liquid equalization tank 302. This facilitates easy removal of the partition plate 404 when cleaning, maintenance, or replacement of the liquid equalization tank 302, greatly improving the ease of use and maintenance efficiency of the device.
[0030] Furthermore, the inside of the equalization tank 302 is provided with a T-shaped groove 402, and a T-shaped block 401 is slidably connected inside the T-shaped groove 402. The T-shaped block 401 and the T-shaped groove 402 are mutually adapted.
[0031] The T-shaped block 401 slides along the T-shaped groove 402 inside the liquid equalization tank 302, which facilitates the quick installation and replacement of the distribution tank 4 and the partition plate 404.
[0032] Furthermore, the top of the equalization tank 302 is provided with an installation groove 303, and a top plate 3 is slidably connected inside the installation groove 303. A waterproof ring 301 is fixedly connected to the surface of the top plate 3.
[0033] The top plate 3 forms an axial sliding fit with the liquid distribution tank 302 through the mounting groove 303. The waterproof ring 301 is deformed under pressure to achieve a seal. The waterproof ring 301 prevents liquid from seeping out from the gap between the top plate 3 and the liquid distribution tank 302, ensuring that all liquid flows out from the first water inlet 403.
[0034] Furthermore, a top plate 3 is movably connected to the surface of the snap-fit block 203, a diverter cylinder 204 is fixedly connected to the bottom of the snap-fit block 203, and a first drainage hole 205 is fixedly connected to the bottom of the diverter cylinder 204.
[0035] The distributor 204 and the first droplet 205 ensure that the liquid enters the equalization tank 302 more evenly, avoiding excessive or insufficient local liquid flow. This helps improve the uniformity of gas-liquid contact.
[0036] Furthermore, the surface of the separator 404 is provided with a second perforation 405. The second perforation 405 on the surface of the separator 404 allows liquid to flow between the two sides of the separator 404. After the liquid enters the equalization tank 302, part of the liquid flows through the distribution channel 4, while the other part of the liquid can be exchanged and redistributed on both sides of the separator 404 through the second perforation 405, and finally flows out from the first perforation 403, making the liquid flow out of the first perforation 403 more uniform, improving the gas-liquid contact effect and separation efficiency.
[0037] Furthermore, the bottom of the distribution tank 4 is uniformly provided with multiple second drainage holes 306, the diameter of which is smaller than that of the first drainage hole 205. Because the diameter of the second drainage hole 306 is smaller than that of the first drainage hole 205, after the liquid is initially dispersed through the first drainage hole 205, it is further finely dispersed through the second drainage hole 306, and uniformly dripped into the packed tower body 1 in the form of smaller droplets.
[0038] Furthermore, both the top plate 3 and the liquid equalization tank 302 are provided with mounting openings 304, and the mounting openings 304 are internally threaded with fixing bolts 305. After the top plate 3 and the liquid equalization tank 302 are installed in place, the fixing bolts 305 are rotated to secure them tightly in the mounting openings 304, thus firmly connecting the top plate 3 and the liquid equalization tank 302 together and ensuring the stability of the device during operation.
[0039] Furthermore, the distribution tank 4 is made of polypropylene composite material. During the operation of the chemical packed tower separation device, the distribution tank 4, made of polypropylene composite material, can withstand the scouring of liquids and the corrosion of chemical raw materials.
[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
