Description

Technical Field

[0001] This utility model relates to the field of distributor technology, and in particular to a high-efficiency mass transfer distributor with a multi-stage channel ring structure. Background Technology

[0002] In process industries such as chemical, petroleum, pharmaceutical, and environmental protection, distillation and absorption towers represent the most concentrated areas of energy and capital investment. With global energy shortages and the advancement of "dual-carbon" goals, unprecedented demands have been placed on energy conservation, consumption reduction, and efficiency improvement in these processes. Simultaneously, the rapid development of high-end chemicals has led to near-stringent requirements for separation precision and product purity control. All of this points to one core issue: the need to maximize mass transfer efficiency within the towers.

[0003] To address this, patent CN222544531U discloses a distributor comprising a first inlet pipe, a second inlet pipe, and several outlet pipes. All outlet pipes are parallel to each other and equally spaced. The outlet end of the first inlet pipe is connected to the midpoint of the second inlet pipe along its length. The second inlet pipe is connected to the midpoint of all outlet pipes along their length. Each outlet pipe has several equally spaced outlet needles arranged in a crisscrossing linear grid pattern. The distance between each outlet needle and its adjacent outlet needle is the same both longitudinally and laterally. This distributor has the advantage of providing uniform fluid distribution.

[0004] While the distributors described above can achieve uniform fluid distribution during use, they are prone to vibration or deformation when subjected to their own weight, liquid load, and potential airflow impacts. Deformation causes the distributor to lose its horizontal position, compromising its carefully designed uniform liquid distribution and drastically reducing mass transfer efficiency. Therefore, it is necessary to design a high-efficiency mass transfer distributor with a multi-stage channel ring structure. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency mass transfer distributor with a multi-stage channel ring structure, in order to solve the problem that existing high-efficiency mass transfer distributors are prone to vibration or deformation when subjected to their own weight, liquid load and possible airflow impact. Deformation will cause the distributor to no longer be horizontal, destroy its carefully designed liquid distribution uniformity, and cause a sharp drop in mass transfer efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency mass transfer distributor with a multi-stage channel ring structure, including a shell;

[0007] A flow guide frame is fixed on the inner wall of the top of the outer shell, a connecting pipe is fixed at the bottom of the flow guide frame, and a distribution chamber is fixed at the bottom of the connecting pipe.

[0008] A support structure is fixed on the inner wall of the bottom of the outer shell. The support structure includes a base frame fixed to the inner wall of the bottom of the outer shell. A support plate is fixed to the end of the base frame away from the outer shell. The support structure also includes connecting rods evenly fixed to the outer wall of the distribution chamber. A positioning plate is fixed to the end of the connecting rod away from the distribution chamber. Positioning holes are evenly opened inside the positioning plate.

[0009] A multi-level lane ring structure is provided above the support structure.

[0010] Furthermore, an inlet pipe is fixed to the top of the outer shell, and a filter structure is fixed to the inner wall of the outer shell above the drainage frame.

[0011] Furthermore, the filter structure includes a filter plate, filter holes, mounting bolts, and a support ring. The support ring is fixed to the inner wall of the outer shell above the flow guide frame. The top of the support ring is provided with a filter plate. Filter holes are evenly opened inside the filter plate. Mounting bolts are evenly inserted through the edge of the filter plate.

[0012] Furthermore, the filter holes are evenly distributed inside the filter plate, and the bottom ends of the mounting bolts all penetrate the filter plate and extend into the interior of the support ring.

[0013] Furthermore, the main view section of the drainage frame is designed with an inclination.

[0014] Furthermore, the multi-stage channel ring structure includes a channel ring body, a connecting pipe, and a nozzle. The channel ring body is evenly disposed on the outside of the distribution chamber. A connecting pipe is evenly fixed on the side of the channel ring body near the distribution chamber. The nozzle is evenly fixed at the bottom end of the channel ring body on the side of the distribution chamber near the outer shell.

[0015] Furthermore, the channel ring body is interconnected with the distribution chamber via a connecting pipe, and the nozzles are evenly distributed at the bottom end of the channel ring body.

[0016] Furthermore, the positioning holes are evenly distributed inside the positioning plate, and the top of the support plate and the bottom of the distribution chamber are fixedly connected.

[0017] Furthermore, the central axis of the distribution chamber and the central axis of the connecting pipe are collinear.

[0018] The present invention provides a high-efficiency mass transfer distributor with a multi-stage channel ring structure, the advantages of which are:

[0019] By incorporating a support structure, the core distribution unit is connected to the bottom support plate and base frame as a whole via connecting rods. It is then fixed to the inner wall of the tower or other internal components via positioning plates and holes, ensuring stable alignment of the entire distributor at the center of the tower and preventing flow deviation. The bottom support formed by the base frame and support plate, together with the upper connecting rods, evenly transfers the weight of the distributor itself and the internal liquid to the tower wall or support ring, preventing structural deformation caused by weight and fluid impact. This ensures long-term operational reliability and enables the device to provide stable support for the multi-stage distribution ring structure, improving the convenience and stability of this high-efficiency mass transfer distributor with a multi-stage distribution ring structure during use.

[0020] By incorporating a multi-stage distribution ring structure and a parallel flow channel network composed of multiple concentrically arranged distribution ring bodies and connecting pipes, the liquid is distributed in multiple stages and finally flows out through equally spaced nozzles. This ensures the formation of numerous and uniformly distributed liquid droplets on the cross-section of the tower, greatly improving mass transfer efficiency. The multi-stage parallel flow channel design provides a larger flow area, enabling the distributor to maintain good distribution effects over a wide range of liquid loads. Its operational flexibility is significantly better than that of traditional distributors, enabling the device to easily and uniformly distribute liquids. This improves the convenience and efficiency of the high-efficiency mass transfer distributor with a multi-stage distribution ring structure during use.

[0021] By incorporating a filtration structure, the filter plates and filter holes effectively intercept solid impurities or suspended matter in the liquid, preventing subsequent nozzle blockage and ensuring long-term stable operation. The evenly distributed filter holes initially distribute the incoming liquid, breaking up high-velocity liquid streams and allowing the liquid to enter the downstream distribution system more smoothly, creating initial conditions for efficient mass transfer. The filter plates are fixed to the support rings by mounting bolts, forming a detachable structure that facilitates regular cleaning or replacement, reducing maintenance costs and improving the maintainability of the equipment. This device enables convenient filtration and pretreatment of liquids, enhancing the convenience and applicability of this high-efficiency mass transfer distributor with a multi-stage distribution ring structure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 The present invention provides a high-efficiency mass transfer distributor with a multi-stage channel ring structure, including a housing 1.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The top of the outer shell 1 is fixed with an inlet pipe 2. A filter structure 3 is fixed on the inner wall of the outer shell 1 above the flow guide 4. The filter structure 3 includes a filter plate 31, filter holes 32, mounting bolts 33 and a support ring 34. The support ring 34 is fixed on the inner wall of the outer shell 1 above the flow guide 4. The top of the support ring 34 is provided with a filter plate 31. Filter holes 32 are evenly opened inside the filter plate 31. Mounting bolts 33 are evenly inserted through the edge of the filter plate 31. The filter holes 32 are evenly distributed inside the filter plate 31. The bottom of the mounting bolts 33 all pass through the filter plate 31 and extend into the interior of the support ring 34. The inner wall of the top of the outer shell 1 is fixed with a flow guide 4. The main view section of the flow guide 4 is designed with an inclination. A connecting pipe 8 is fixed at the bottom of the flow guide 4. A distribution chamber 7 is fixed at the bottom of the connecting pipe 8.

[0032] After the liquid enters the housing 1 from the inlet pipe 2, it first reaches the filter structure 3. The liquid passes through the filter holes 32 evenly distributed on the filter plate 31, and the solid particles in it are intercepted by the filter plate 31. After filtration and preliminary equalization, the clean liquid flows downward into the inclined guide frame 4 through the central area of ​​the support ring 34. The entire filter unit is fastened by the mounting bolt 33 to ensure structural stability under fluid impact.

[0033] Reference Figures 1-6 A support structure 6 is fixed on the inner wall of the bottom of the outer shell 1. The support structure 6 includes a base frame 63 fixed on the inner wall of the bottom of the outer shell 1. A support plate 65 is fixed at the end of the base frame 63 away from the outer shell 1. The support structure 6 also includes connecting rods 64 that are evenly fixed on the outer wall of the distribution chamber 7. A positioning plate 61 is fixed at the end of the connecting rods 64 away from the distribution chamber 7. Positioning holes 62 are evenly opened inside the positioning plate 61. The positioning holes 62 are evenly distributed inside the positioning plate 61. The top end of the support plate 65 is fixedly connected to the bottom end of the distribution chamber 7. The central axis of the distribution chamber 7 and the central axis of the connecting pipe 8 are collinear.

[0034] The support structure 6 is a spatial frame system. The base frame 63 is fixed to the inner wall of the bottom of the tower, providing basic support for the core. The support plate 65 is fixed to the bottom of the distribution chamber 7 and bears its vertical load. Multiple connecting rods 64 connect the distribution chamber 7 and the surrounding positioning plate 61 in a radial pattern, effectively resisting lateral forces and maintaining centering. The positioning plate 61 limits the nozzle 53 through the positioning hole 62 on it, preventing the nozzle 53 from shaking when discharging water, thus achieving a firm and precise installation of the entire distributor in the tower.

[0035] Reference Figures 1-5 A multi-level channel ring structure 5 is provided above the support structure 6. The multi-level channel ring structure 5 includes a channel ring body 51, a connecting pipe 52, and a nozzle 53. The channel ring body 51 is evenly arranged on the outside of the distribution chamber 7. The connecting pipe 52 is evenly fixed on the side of the channel ring body 51 near the distribution chamber 7. The nozzles 53 are evenly fixed at the bottom end of the channel ring body 51 on the side of the distribution chamber 7 near the outer shell 1. The channel ring body 51 is interconnected with the distribution chamber 7 through the connecting pipe 52. The nozzles 53 are evenly distributed at the bottom end of the channel ring body 51.

[0036] The liquid, which has been collected and initially stabilized in the distribution chamber 7, is transported to each concentric channel ring body 51 through the evenly distributed connecting pipes 52. The liquid flows in a ring in each channel ring body 51, further dissipating kinetic energy and stabilizing the pressure. Finally, the nozzles 53, which are installed at equal intervals at the bottom of the channel ring body 51, spray the liquid evenly and stably onto the packing bed below, achieving efficient mass transfer across the entire tower cross section.

[0037] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
