DETAILED DESCRIPTION

[0036] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0037] A packed column according to an embodiment of the present application is described below with reference to the accompanying drawings. As shown in Figures 1 to 5 The packed column according to an embodiment of the present application includes a column body 1, a liquid inlet portion 2, and a liquid distributor 3.

[0038] The column body 1 is provided with a liquid inlet hole 11, one end of which is located outside the column body 1 and the other end of which is located inside the column body 1. Specifically, a pipe body outside the column body 1 is connected to the end of the liquid inlet hole 11 inside the column body 1, so as to introduce liquid into the column body 1.

[0039] The liquid inlet portion 2 is arranged on the inner wall surface of the column body 1, and has a liquid inlet groove extending along the circumference of the column body 1. The liquid inlet groove is in communication with the liquid inlet hole 11 through a liquid inlet pipe 14, and the liquid inlet portion 2 has a plurality of first liquid outlet openings 21 in communication with the liquid inlet groove. Specifically, the inner wall surface of the liquid inlet portion 2 forms the liquid inlet groove, and the liquid in the liquid inlet hole 11 can be introduced into the liquid inlet groove through the liquid inlet portion 2 and then discharged from the first liquid outlet openings 21.

[0040] The liquid distributor 3 is arranged in the column body 1, and includes a plurality of first liquid distribution grooves 31, which are in one-to-one correspondence with the plurality of first liquid outlet openings 21 of the liquid inlet portion 2. Specifically, the first liquid distribution grooves 31 are a plurality of grooves, and the packed column according to an embodiment of the present application provides liquid for the liquid distributor 3 by arranging the liquid inlet portion 2 in the column body 1, opening a plurality of first liquid outlet openings 21 on the liquid inlet portion 2, and connecting the plurality of first liquid outlet openings 21 on the liquid inlet portion 2 with the plurality of first liquid distribution grooves 31. That is, the liquid introduced into the column body 1 from the liquid inlet hole 11 does not need to be directly connected to the first liquid distribution grooves 31, and the positioning of the liquid inlet hole on the column body 1 does not need to be considered, thereby reducing the installation difficulty of the liquid distributor 3 and increasing the work efficiency.

[0041] Therefore, the packed column according to an embodiment of the present application has the advantage of facilitating the installation of the liquid distributor 3.

[0042] As shown in Figures 3 to 5 In some embodiments, the liquid distributor 3 includes a liquid distribution frame 34, a plurality of first liquid distribution grooves 31, a plurality of second liquid distribution grooves 32, and a plurality of flow dividing plates 33. For example, the liquid distributor 3 is a groove type liquid distributor.

[0043] The liquid distribution frame 34 includes a bottom plate 35 and a mounting frame, and the bottom plate 35 has a plurality of liquid distribution holes 37 extending therethrough in the up-down direction.

[0044] The first liquid distribution grooves 31 are connected to the bottom plate 35 through the mounting frame, the length direction of the first liquid distribution grooves 31 is the first horizontal direction, and the first liquid distribution grooves 31 are arranged at intervals in the second horizontal direction. The two ends of the first liquid distribution grooves 31 in the first horizontal direction are respectively communicated with a first liquid outlet 21, and the bottom of the first liquid distribution grooves 31 is provided with a plurality of first liquid drop openings 311 arranged at intervals in the first horizontal direction. Any two of the first horizontal direction, the second horizontal direction and the up-down direction are perpendicular to each other. The first horizontal direction can be the left-right direction, the second horizontal direction can be the front-back direction, and the front-back direction, the left-right direction and the up-down direction are shown by arrows in the figure. For example, the length direction of the first liquid distribution grooves 31 is the left-right direction, and the first liquid distribution grooves 31 are arranged at intervals in the front-back direction. The left and right ends of the first liquid distribution grooves 31 are respectively communicated with a first liquid outlet 21, and the bottom of the first liquid distribution grooves 31 is provided with a plurality of first liquid drop openings 311 arranged at intervals in the left-right direction.

[0045] The second liquid distribution grooves 32 are arranged on the bottom plate 35, the length direction of the second liquid distribution grooves 32 is the first horizontal direction, the second liquid distribution grooves 32 are arranged at intervals in the second horizontal direction, the second liquid distribution grooves 32 are arranged one by one below the first liquid distribution grooves 31, the inlet of the second liquid distribution grooves 32 faces the upper side, and each second liquid distribution groove 32 is communicated with at least one liquid distribution hole 37. For example, the length direction of the second liquid distribution grooves 32 is the left-right direction, and the second liquid distribution grooves 32 are arranged at intervals in the front-back direction.

[0046] The distribution plate 33 extends along the first horizontal direction, the distribution plate 33 has a plurality of distribution hole groups penetrating it in the up-down direction, the distribution plates 33 are arranged one by one below the first liquid distribution grooves 31, and the distribution plates 33 are arranged one by one above the second liquid distribution grooves 32. Specifically, the distribution plate 33 is located between the corresponding first liquid distribution groove 31 and the second liquid distribution groove 32 in the up-down direction, the liquid discharged downward from the first liquid drop opening 311 of the first liquid distribution groove 31 falls on the distribution plate 33, then is distributed through the distribution hole group, and then falls into the second liquid distribution groove 32 again, so as to uniformly flow downward from the liquid distribution hole 37 on the bottom plate 35.

[0047] As Figure 3As shown, in some embodiments, the top surface of the diversion plate 33 includes a first inclined surface 331 and a second inclined surface 332. The first inclined surface 331 and the second inclined surface 332 intersect to form a diversion line, which extends along a first horizontal direction and is located directly below the corresponding first liquid distribution tank 31. Each of the first inclined surface 331 and the second inclined surface 332 is inclined downward in a direction away from the diversion line in a second horizontal direction. Specifically, the diversion plate 33 has an inverted V-shaped structure, and the diversion line is the boundary line between the first inclined surface 331 and the second inclined surface 332. The diversion line is located directly below the first drip outlet 311 of the corresponding first liquid distribution tank 31, so that the liquid discharged from the first drip outlet 311 of the first liquid distribution tank 31 can flow evenly to the first inclined surface 331 and the second inclined surface 332.

[0048] Both the first inclined surface 331 and the second inclined surface 332 are provided with a plurality of diversion hole groups spaced apart in the first horizontal direction. Each diversion hole group includes a plurality of diversion holes 333 spaced apart in the second horizontal direction, so that the liquid flowing downward from the first inclined surface 331 and the second inclined surface 332 can enter the plurality of diversion holes 333 spaced apart in the second horizontal direction, thereby making the diversion plate 33 have a good diversion effect. For example, the diversion line extends in the left-right direction, and each of the first inclined surface 331 and the second inclined surface 332 is inclined downward in the front-back direction away from the diversion line, and each diversion hole group includes a plurality of diversion holes 333 spaced apart in the front-back direction.

[0049] like Figure 3 As shown, in some embodiments, the cross-sectional area of ​​the one adjacent to the flow divider line among two adjacent flow dividers 333 in each flow divider group is smaller than the cross-sectional area of ​​the one farther from the flow divider line among two adjacent flow dividers 333. This results in a smaller flow passage cross-section for the flow divider 33 adjacent to the flow divider line and a larger flow passage cross-section for the flow divider 33 farther from the flow divider line, thus making the flow distribution effect of the multiple flow dividers 333 more uniform. The flow dividers 333 are rectangular or circular holes. For example, the cross-sectional area of ​​the multiple flow dividers 333 in each flow divider group increases in the front-back direction away from the flow divider line. The first inclined surface 331 is located in front of the second inclined surface 332. The cross-sectional area of ​​the multiple flow dividers 333 in each flow divider group on the first inclined surface 331 increases forward, and the cross-sectional area of ​​the multiple flow dividers 333 in each flow divider group on the second inclined surface 332 increases backward.

[0050] like Figure 3As shown, in some embodiments, one of the two adjacent shunt holes 333 of each shunt hole group adjacent to the shunt line is smaller in size in the first horizontal direction than the other of the two adjacent shunt holes 333 away from the shunt line. For example, the size of the plurality of shunt holes 333 of each shunt hole group on the first inclined surface 331 increases in the left-right direction forward, and the size of the plurality of shunt holes 333 of each shunt hole group on the second inclined surface 332 increases in the left-right direction backward.

[0051] In some embodiments, the liquid inlet part 2 and the liquid inlet groove are both annular structures, the liquid inlet part 2 is annularly arranged on the peripheral side of the liquid distributor 3, the plurality of first liquid outlets 21 are arranged on the inner peripheral side of the liquid inlet part 2, and the outer peripheral side of the liquid inlet part 2 is connected to the inner peripheral surface of the tower body 1.

[0059] The liquid inlet part 2 (the liquid inlet groove) is a rectangular annular structure, and the liquid inlet part 2 (the liquid inlet groove) comprises a first section, a second section, a third section and a fourth section connected in sequence.
