[0003] The liquid phase of the packed tower requires uniform spraying, otherwise it will directly affect the contact efficiency of the packing surface. However, the liquid distributor of the existing packed tower sprays unevenly, and the contact efficiency of the packing surface is not high, resulting in low efficiency of the packed tower; and the tower height is relatively high. Summary of the invention

[0007] The cylinder, the jacketed cylinder and the liquid inlet form an annular liquid feed space. The liquid enters the annular liquid feed space from the liquid inlet. A buffer plate is arranged in the jacketed cylinder to play a buffering role. The liquid in the space enters the tower through the through holes on the inner wall of the cylinder.

[0008] An annular space is formed between the outer wall of the D-shaped ring and the inner wall of the cylinder, and the liquid entering the tower is in the annular space.

[0009] The distribution groove is U-shaped, with liquid distribution holes on the bottom and sides and a reinforcing plate inside.

[0010] One end of the distribution groove is connected to the arch plate, and the other end is connected to the vertical plate. The bottom of the distribution groove is fixedly connected to the supporting plate.

[0011] A toothed weir is arranged on the arched plate at the connection between the distribution trough and the arched plate; and a toothed weir is arranged on the vertical plate at the connection between the distribution trough and the vertical plate.

[0012] It also includes beams and stiffener plates, and the beams and vertical plates constitute reinforced beams.

[0013] The heights of the arched plates and the vertical plates are higher than the height of the distribution grooves.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention adopts a jacketed cylinder, in which a buffer plate is arranged to play a buffering role and ensure stable flow of liquid.

[0016] 2.

[0023] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-4 As shown, a high-efficiency liquid distributor for a packed tower includes an arch plate 1, a vertical plate 2, a rib plate 3, a beam 4, a support plate 5, a distribution trough 6, a reinforcing plate 7, a cylinder 8, a jacketed cylinder 9, a liquid inlet 10 and a buffer plate 11.

[0025] The cylinder 8 is a circular cylinder, and the support plate 5 is fixedly connected to the cylinder 8 horizontally. The arch plate 1 and the vertical plate 2 are welded together to form a D-shaped ring, and the two D-shaped rings are welded back to back symmetrically on the support plate 2 with a gap in the middle. The beam 4 and the vertical plate 2 form a reinforcing beam, which can effectively reduce the tower height. The rib plate 3 is welded to the beam 4 to play a role of fixing and reinforcing.

[0026] An oblong through hole is circumferentially provided on the side wall of the cylinder 1 , which is located above the support plate 5 . The jacket cylinder 9 is welded to the outer wall of the cylinder 1 , located at the oblong through hole and covers the outside of the oblong through hole. The liquid inlet 10 is fixedly connected to the jacket cylinder 9 .

[0027] A plurality of distribution grooves 6 are arranged in a row and fixed in the D-shaped ring, and there is a spacing between the distribution grooves 6, and the spacing is the same. The distribution groove 6 is made of steel plate and is in a U-shape. The bottom and side surfaces are provided with liquid distribution holes, and a reinforcing plate 7 is provided inside to strengthen and stabilize.

[0028] One end of the distribution trough 6 is welded to the arch plate 1, and the other end is welded to the vertical plate 2. The bottom of the distribution trough 6 is welded to the support plate 5. The arch plate 1 is provided with a toothed weir at the connection between the distribution trough 6 and the arch plate 1; the vertical plate 2 is provided with a toothed weir at the connection between the distribution trough 6 and the vertical plate 2. The heights of the arch plate 1 and the vertical plate 2 are higher than the height of the distribution trough 6.

[0029] The cylinder 8, the jacket cylinder 9 and the liquid inlet 10 constitute an annular liquid feed space. The liquid enters the annular liquid feed space from the liquid inlet 10. A buffer plate 11 is provided in the jacket cylinder 9 to play a buffering role and ensure stable flow of the liquid. The liquid in the space enters the tower through the oblong through hole in the side wall of the cylinder.

[0030] The outer wall of the D-shaped ring and the inner wall of the cylinder 8 form an annular space, and the liquid level in the tower rises steadily in this annular space. It plays the role of a conventional liquid distributor first-stage slot, and can also reduce the tower height; at the same time, the feed at both ends of the distribution slot 6 ensures that the liquid is evenly distributed.

[0031] The liquid enters the annular liquid feed space formed by the cylinder 8, the jacket cylinder 9 and the liquid inlet 10 from the liquid inlet 10. The liquid flows upward steadily through the buffer plate 11 and enters the tower steadily through the oblong holes around the cylinder 8. The tower is formed by the annular space between the outer wall of the D-shaped ring and the inner wall of the cylinder 8. The liquid level in the tower rises steadily in this annular space. The liquid rises to the toothed weir of the vertical plate 2 and the arch plate 1 and enters the distribution trough 6. The liquid in the distribution trough 6 is evenly distributed on the filler through the liquid distribution holes of the trough body, realizing the gas-liquid mass transfer function.

[0032] The invention realizes uniform liquid phase spraying, has high contact efficiency on the surface of the packing, improves the efficiency of the packing tower, and reduces the tower height.
