Description

Technical Field

[0001] This utility model relates to the field of liquid distribution equipment technology, and in particular to a liquid distributor and a reactor. Background Technology

[0002] Bisphenol A (BPA) is formed by the dehydration condensation of phenol and acetone under cationic catalysis. It possesses two hydroxyl groups and is primarily used in the production of aromatic polycarbonate (PC) and epoxy resins. Aromatic polycarbonate (PC), due to its excellent light transmittance, impact resistance, UV resistance, dimensional stability, and good molding and processing properties, is widely used in building materials, automotive parts, medical devices, and electronic components. It has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics and is showing a trend towards large-scale, integrated development. The production processes for aromatic polycarbonate (PC) include interfacial phosgenation polycondensation, traditional melt transesterification, and non-phosgenated melt transesterification polycondensation. The main raw material for each process is BPA. As the market size of aromatic polycarbonate (PC) continues to expand, the demand for BPA is also increasing daily.

[0003] In the bisphenol A primary condensation reaction, the catalyst activity decreases as the reaction proceeds. To maintain a high reaction conversion rate, the phenol-acetone feed ratio is usually adjusted accordingly, and thorough mixing of the phenol-acetone feed at different ratios is crucial. To improve the reaction efficiency of the liquid-solid two-phase reaction equipment, a liquid distributor must be added to the equipment to ensure uniform distribution of the liquid in the solid bed. A uniformly distributed liquid distributor is an important device for improving reaction efficiency, and research on its uniform distribution performance is very important. Existing equipment uses a feed mixer installed in a pipeline. Production operation shows that the liquid flow is not a simple plug flow, but exhibits channeling, flow deviation, and wall adhesion, resulting in reduced mass transfer efficiency.

[0004] Existing patent 1, CN208627348U, discloses a novel separatory funnel holder, including a base with a support platform on the base. The support platform has a detachable support rod, and multiple height-adjustable separatory funnel support discs are fitted onto the support rod. These separatory funnel support discs are arranged vertically at intervals, and each separatory funnel support disc has multiple separatory funnel holes around its circumference. The separatory funnel holes on adjacent separatory funnel support discs are staggered. Each separatory funnel hole has an opening on one side that communicates with it, and the width of the opening is smaller than the diameter of the separatory funnel hole. The support rod has multiple height-adjustable separatory funnel support discs, and each separatory funnel support disc has multiple separatory funnel holes around its circumference. Each separatory funnel support disc can be used to hold multiple separatory funnels. This allows for an increase in the number of separatory funnels that can be held without continuously expanding the separatory funnel holder; only the area occupied by the support platform is needed. Furthermore, the multiple funnel holes on the adjacent funnel support plates are staggered, ensuring that the funnels on each support plate do not interfere with each other during operation. However, the technical field, technical solution, technical problem, and technical effect of Existing Patent 1 are unrelated to liquid distribution. Existing Patent 1's principle is to store multiple funnels by designing multi-layered support plates to prevent leakage. Existing Patent 1 has a complex structure and occupies a large area.

[0005] Existing patent 2: CN112474087B discloses a liquid distributor, a multi-stage high-efficiency distributor, and a method for spraying washing liquid. The multi-stage high-efficiency distributor suitable for liquid spraying includes a liquid distributor as a central distributor. The liquid distributor includes a vertically sealed cylinder with an upper feed chamber and a lower distribution chamber. The inner wall of the feed chamber is provided with multiple spiral blades from top to bottom. The inner edge of the spiral blades is connected to a vertically fixed column located in the middle. The distribution chamber includes multiple partitions that divide the distribution chamber into multiple independent chambers. Each independent chamber has a through hole on its outer wall, and an outlet pipe is connected to the through hole. Furthermore, each independent chamber has the same volume. All outlet pipes are evenly distributed and tangentially arranged along the outer wall of the distribution chamber. The outlet pipe of each central distributor is connected to a radial distributor through a connecting pipe. The radial distributor includes at least one branch distributor, which is either a single-stage branch distributor or two or more branch distributors connected in series. The branch distributor includes an outlet pipe that is connected downward to a vertically extending pipe. The bottom of the vertically extending pipe is connected to a nozzle. The design incorporates spiral blades and evenly distributed independent chambers to ensure uniform fluid distribution. This swirling structure not only provides a more uniform distribution but also increases liquid velocity and kinetic energy, thereby improving washing efficiency. Multiple high-efficiency distributors, outlet pipes of varying lengths, connecting pipes of different lengths, and vertical extension pipes of varying lengths can be incorporated to ensure uniform distribution of the washing liquid through the high-efficiency distributors. This results in consistent spraying effects from all nozzles and allows for more accurate calculation of the spray overlap zone when arranging the nozzles in space. Through clever arrangement, the spray overlap zone between different nozzles is well controlled, ultimately achieving uniform and complete washing liquid coverage across the spray washing cross-section. Existing Patent 2 works by using multiple rotating spiral blades to disperse the liquid and redistribute it under centrifugal force. However, Existing Patent 2 has a complex structure, occupies a larger area, and is more expensive.

[0006] Existing patent three, CN112474087B, discloses a liquid distributor for chemical production, including a central inlet manifold, a liquid distribution disc, and liquid distribution pipes. The central inlet manifold is vertically installed at the center of the liquid distribution head. The upper end of the central inlet manifold is connected to a flange via a connecting pipe. Multiple liquid distribution pipes are evenly spaced on the side of the liquid distribution head. The liquid distribution head is a cylindrical hollow cylinder structure. The liquid distribution pipes form an angle of 5-15° with the horizontal plane. Adjacent liquid distribution pipes are connected through multiple liquid distribution discs. The bottom of each liquid distribution disc has several evenly distributed outlet holes. The multiple liquid distribution pipes connected to the liquid distribution discs provide a stable structure and facilitate uniform liquid distribution. The 5-15° angle between the liquid distribution pipes and the horizontal plane facilitates liquid outflow and uniform distribution, improving liquid distribution efficiency. Existing patent three works by providing multiple branch pipes to disperse and distribute the liquid within the main pipe, but this results in lower uniformity, a complex structure, higher cost, and a larger footprint.

[0007] Liquid distributors include pressure distributors (nozzle type, pipe type) and gravity distributors (trough type, disc type). Among them, the collection trough type liquid distributor is the most common liquid distributor, but it has a complex structure, occupies a large area, and has a high cost. Utility Model Content

The first liquid distributor 4 has a diameter of 300mm, a height of 50mm, and 59 evenly distributed liquid distribution holes 9 with a diameter of 30mm. The main pipe inlet (inlet 10) has a diameter of 76mm, and the rectangular discharge port (first discharge port 3) has a size of 20mm×50mm.

[0107] The remaining 50% of the liquid flowing from the rectangular outlet (second outlet 8) on the main pipe enters the second distribution plate 5 through the six rectangular outlets (first outlet 3) above the second main pipe for further distribution. 30% of the liquid will be evenly sprayed into the catalyst bed, and the liquid near the main pipe area will be evenly distributed through the third distribution plate 6. Simultaneously, the remaining 20% ​​of the liquid will enter the third distribution plate area through the outlet (second outlet 8) at the connection between the second distribution plate (second distribution plate 5) and the main pipe. The second liquid distribution plate (second distribution plate 5) has a diameter of 2000 mm and is equipped with 198 distribution holes (distribution holes 9), each with a diameter of 30 mm. The outlet (second outlet 8) at the connection between the second distribution plate (second distribution plate 5) and the main pipe has a diameter of 20 mm.

[0108] The remaining 20% ​​of the liquid in the main pipe flows to the third distribution plate 6 area under the influence of gravity. The liquid enters the third distribution plate 6 through the six rectangular outlets (first outlet 3) above it. The liquid from the third distribution plate 6 is then evenly sprayed into the catalyst bed. The distribution plate (third distribution plate 6) has a diameter of 1000 mm and is evenly distributed with 172 distribution holes 9, each with a diameter of 30 mm. At the connection between the third distribution plate (third distribution plate 6) and the main pipe, there are outlets with a diameter of 10 mm (second outlet 8) to ensure that the liquid in the feed main pipe (pipe body 1) is completely drained.

[0109] The diameter of the distribution plate (distribution plate 2) of the entire liquid distributor is different from that of the outlet (second outlet) at the main pipe connection position. Its main function is to ensure that 95% of the liquid is evenly distributed in the first distribution plate (first distribution plate 4) and the second distribution plate (second distribution plate 5), and the third distribution plate (third distribution plate 6) distributes the remaining liquid again, thereby improving the distribution efficiency. The second distribution plate (second distribution plate 5) is larger than the first distribution plate (first distribution plate 4). The first distribution plate 4 performs coarse distribution of 50% of the liquid, and the second distributor (second distribution plate 5) performs secondary distribution of the remaining 95% of the liquid, evenly spraying the liquid into the catalyst bed.

[0110] In addition, this invention also provides a reactor, including the liquid distributor described above.

[0111] The beneficial effects of adopting the technical solution of this utility model are: the liquid in the tube is distributed by multiple dispensing discs, the multi-stage dispensing process improves uniformity, simplifies the structure of the distributor, reduces the size of the equipment, and reduces costs.
