[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] A liquid distributor according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] like Figure 1-12As shown, an embodiment of the present invention proposes a liquid distributor, comprising: a bottom plate 3 and a partition plate 2, the bottom plate 3 is arranged in a horizontal direction, and the bottom plate 3 is provided with a plurality of through holes 6 in a vertical direction; a plurality of partition plates 2 are provided, and the partition plates 2 are detachably connected to the upper end surface of the bottom plate 3, and the plurality of partition plates 2 are arranged to separate the upper end surface of the bottom plate 3 into a main groove 10 and a plurality of branch grooves 12, the main groove 10 is located in the middle of the bottom plate 3, and the branch grooves 12 are located on both sides of the main groove 10, the main groove 10 is connected to the branch grooves 12, the width of the main groove 10 is greater than the width of the branch grooves 12, and the through holes 6 are located inside the main groove 10 and the branch grooves 12, and each branch groove 12 is connected to a baffle plate 9 on one side close to the edge of the bottom plate 3, and the two sides of the baffle plate 9 are detachably connected to the two partition plates 2 constituting each branch groove 12, and the lower end surface of the baffle plate 9 is plugged into the bottom plate 3; all components of the liquid distributor are made of carbon fiber material.

[0035] The embodiment of the present invention provides a partition plate 2 to separate the upper end area of ​​the bottom plate 3 into a main groove 10 and a branch groove 12, and provides a baffle plate 9, so that the liquid falling from above can first enter the main groove 10, and then evenly flow to each branch groove 12, thereby realizing automatic and uniform distribution of the liquid, and forming a certain liquid level in the branch groove 12, and finally falling through the through holes 6 opened in the main groove 10 and the branch groove 12, so that the liquid is evenly distributed on the top of the packing layer and flows evenly along the surface of the packing, avoiding liquid deviation, channel flow, wall flow and the like, and ensuring that the gas-liquid two phases can fully contact on the entire cross section of the packing layer.

[0036] All parts of the liquid distributor are made of carbon fiber material, which can improve the corrosion resistance, impact resistance and high temperature resistance of the liquid distributor.

[0037] It should be noted that carbon fiber materials have the advantages of good corrosion resistance, low density, high specific strength, good toughness, easy processing, and good high temperature resistance. Compared with the original liquid distributor made of ceramic materials, it has the advantages of light weight, good pressure resistance, and good impact resistance. Compared with the original liquid distributor made of polymer materials, it has the advantage of good strength in high temperature environment.

[0038] Furthermore, the baffle plate 9 is fixedly connected to the side of the partition plate 2 by bolts, and each side is connected with a plurality of bolts from top to bottom.

[0039] Further, if Figure 4 , 8 As shown, an insert block 15 is processed at the bottom of the baffle plate 9, and a fourth slot 17 is opened on the upper end surface of the bottom plate 3. The insert block 15 and the fourth slot 17 are sealed and plugged together. After the baffle plate 9 is inserted into the fourth slot 17, it is fixedly connected by bolts, which can improve the sealing and stability between the baffle plate 9 and the bottom plate 3.

[0040] In some embodiments, Figure 1-3 As shown, the liquid distributor further includes a clamp 5, and a plurality of clamps 5 are provided, and the clamps 5 are detachably connected to the upper end of each group of partition plates 2. By providing the clamps 5, the partition plates 2 can remain in a vertical state when subjected to liquid static pressure and impact, thereby improving the pressure resistance and impact resistance of the partition plates 2.

[0041] In some embodiments, Figure 6 As shown, the upper end of the partition plate 2 is provided with a plurality of first slots 14, the card 5 is in the shape of a long strip, the card 5 and the first slots 14 are plugged into each other, and the card 5 and the partition plate 2 are perpendicular to each other. The card 5 and the partition plate 2 are connected by plugging, which is convenient for disassembly and assembly. The card 5 and the partition plate 2 are perpendicular to each other, which can improve the supporting force of the card 5 on the partition plate 2.

[0042] In some embodiments, Figure 4 As shown, the partition plate 2 and the bottom plate 3 are plugged into each other, and a second slot 13 is provided on the upper end surface of the bottom plate 3. The partition plate 2 is inserted into the second slot 13 and fixedly connected by bolts. The plug-in connection can improve the sealing and stability of the connection between the partition plate 2 and the bottom plate 3. It should be noted that the through hole 6 is Figure 1 It has been marked in Figure 4 The through holes are not shown.

[0043] Further, if Figure 6 As shown, an insert block 15 is processed at the bottom of the partition plate 2 to improve the sealing and stability of the connection between the partition plate 2 and the second slot 13.

[0044] In some embodiments, Figure 9-12 As shown, the cross section of the through hole is circular, rectangular or other shapes, the longitudinal section of the through hole is rectangular, upper conical, lower conical, hourglass or other shapes, and the arrangement of the through holes is triangular, rectangular, circular or other shapes. Different control effects on the fluid can be achieved through different opening methods, such as controlling the dripping speed of the liquid, controlling the size of the droplet, or the shape of the liquid when it falls.

[0045] In some embodiments, Figure 1 As shown, notches 31 are respectively provided on both sides of the bottom plate 3 , and the notches 31 are gaps for gas flow formed between the bottom plate 3 and the inner cavity of the equipment. The main baffle 4 is detachably connected to the bottom plate 3 at the notches 31 .

[0046] During the rising process, the gas realizes mass transfer with the liquid sprayed down from the distributor, that is, the exchange of gas-liquid components. Due to the influence of the central bottom plate 3 of the distributor, the gas is forced to cross-flow horizontally when rising. Finally, it rises to the upper space through the gaps 31 on both sides. After passing through multiple liquid distributors of the same type, the contact time between the gas and liquid phases can be increased, providing good contact conditions for the gas and liquid phases. By utilizing the concentration difference and phase equilibrium relationship between the gas and liquid phases, the mass transfer process of the substance between the gas and liquid phases is realized, thereby achieving the purpose of chemical operations such as separation, absorption, and desorption.

[0047] Compared with traditional liquid distributors, this liquid distributor can achieve gas-liquid mass transfer function while realizing liquid distribution, achieving two uses in one, reducing the amount of filler and lowering the tower height, achieving better mass transfer effect, and reducing costs.

[0048] It should be noted that in most packed towers, the liquid flows downward from the top of the tower and the gas flows upward from the bottom of the tower. The large concentration difference between the gas and liquid phases provides the driving force for mass transfer. According to the basic principle of mass transfer - Fick's law, substances will diffuse from high-concentration areas to low-concentration areas. In packed towers, the media in the gas phase and liquid phase will transfer mass when they come into contact due to the concentration difference.

[0049] Furthermore, the cross section of the inner cavity of the tower is circular, and the bottom plate 3 is made of a circular plate with notches 31 cut on both sides.

[0050] Furthermore, two notches 31 are respectively located at two opposite sides of the bottom plate 3 .

[0051] Furthermore, the main baffle plate 4 is plugged into the bottom plate 3. A third slot 11 is provided on the bottom plate 3, and the main baffle plate 4 is inserted into the third slot 11 and fixedly connected by bolts.

[0052] Further, if Figure 7 As shown, an insert block 15 is fixedly connected to the bottom of the main baffle 4 , which can improve the sealing and stability of the connection between the insert block 15 at the lower end of the main baffle 4 and the third slot 11 .

[0053] In some embodiments, the branch groove 12 is a strip-shaped groove, and two adjacent partition plates 2 are arranged in parallel and in parallel with the main baffle plate 4 .

[0054] In some embodiments, the ratio of the width of the main groove 10 to the width of the branch groove 12 is 3.4 to 5.2. This ratio is the optimal distribution ratio, under which the liquid falling into the main groove 10 can be distributed to each branch groove 12 more quickly, achieving the balance and stability of the liquid level in the liquid distributor and shortening the liquid distribution time.

[0055] In some embodiments, Figure 1-3As shown, the bottom of the bottom plate 3 is detachably and fixedly connected with a plurality of support beams 7. The whole liquid distributor can be supported so that the bottom plate 3 is stably supported on the inner wall support ring 1 of the tower.

[0056] It should be noted that support structures such as support blocks and inner wall support rings 1 are usually fixed on the inner wall of the tower to cooperate with supporting the liquid distributor.

[0057] Furthermore, the support beam 7 is fixedly connected to the base plate 3 by bolts.

[0058] Furthermore, the support beams 7 are evenly arranged at the bottom of the bottom plate 3, so that the entire liquid distributor is evenly stressed. Two adjacent support beams 7 are parallel to each other.

[0059] Furthermore, the material of the inner wall support ring 1 is glass-lined.

[0060] In some embodiments, Figure 1-3 As shown, each support beam 7 is connected to a plurality of adjustment support rods 8, and the horizontality of the bottom plate 3 can be adjusted and the liquid distributor can be supported by adjusting nuts 16.

[0061] It should be noted that the adjustable support rod 8 can be understood as a height adjustment mechanism with a supporting function, which can have various forms and will not be described in detail here.

[0062] Further, the adjustable support rods 8 are arranged at both ends of each support beam 7. In this embodiment, the inner wall of the tower is fixedly connected with an inner wall support ring 1 for supporting the liquid distributor, and both ends of the support beam 7 are supported on the inner wall support ring 1 through the adjustable support rods 8.
