Background
The corrugated structured packing has the advantages of large flux, small resistance, high efficiency, convenient installation and the like, and is widely applied to the fields of oil refining, petrifaction, chemical industry, light industry and environmental protection. The angle of inclination of the corrugations of a typical corrugated structured packing to the horizontal is typically in the range of 45 to 60 degrees. The corrugated structured packing is vertically arranged, the wave crest directions of two adjacent sheets are arranged in opposite directions to leave a gap for liquid to flow downwards, and the corrugated structured packing of each layer stacked up and down are stacked at 90 degrees in a staggered manner.
Because the corrugation trend of the corrugated structured packing is not completely consistent with the flow direction of the fluid in the tower, when the fluid at the boundary of the packing enters the next layer of the stacked packing from one layer of the packing, the flow direction of the fluid is changed rapidly, the flow resistance of the gas is increased, and the processing capacity of the packing is reduced.
In addition, it is also desirable to increase the mass transfer efficiency of the filler, that is, to increase the specific surface area of the filler, to improve the wettability of the liquid on the surface of the filler, and to form an effective mass transfer liquid film.
To this end, the present applicant, in the invention patent application with application No. 201210367704.3, entitled "a composite corrugated structured packing with guide corrugations", filed on 28.9/2012, discloses a composite corrugated structured packing whose surface is machined with transverse and longitudinal small corrugations (the transverse small corrugations are not shown in the abstract drawing of the invention patent application or in fig. 1, but the longitudinal small corrugations are shown in a partial detail view circled by a dotted line, and the transverse and longitudinal small corrugations existing on the structured packing surface at the same time are shown in fig. 2 of the invention patent application), and is configured as a corrugated plate with oblique corrugations and edge guide corrugations. Wherein, the inclination angle between the oblique ripple and the horizontal direction is 45 degrees to 60 degrees, and the flow guide ripple is processed at the two sides of the ripple-shaped plate, the included angle between the flow guide ripple and the oblique ripple is 135 degrees to 175 degrees, and the section of the flow guide ripple is in a sine wave shape.
The technical scheme disclosed in the above patent application increases the specific surface area of the packing through the transverse and longitudinal small corrugations, and simultaneously reduces the flow resistance of the fluid between the packings by establishing continuous flow lines at the positions where one layer of the packing is transited to the other layer of the packing through the guide corrugations. However, the presence of the small transverse corrugations hinders the downward flow of liquid in the corrugations. Also, the guide corrugations of both sides of the corrugated plate and the corrugated body of the corrugated plate have different cross sections, which brings about processing complexity.
It is therefore desirable to provide a corrugated structured packing that not only achieves sufficient infiltration of the mass transfer fluid by increasing the specific surface area of the packing and improves the mass transfer efficiency, but also achieves convenient flow of the fluid between each layer of the installed corrugated structured packing in a structural form that facilitates simple processing.

It is understood that it is possible to design one portion of the fluid sink to be continuous and another portion of the fluid sink to be intermittent without departing from the spirit of the invention. The continuous liquid guide groove structure is beneficial to guiding the fluid and improving the flow speed. The discontinuous liquid guide groove structure is more beneficial to the distribution of the liquid than the continuous liquid guide groove structure and can further increase the specific surface area of the filler.
According to the utility model discloses an implementation form of corrugated structured packing, the degree of depth of liquid guide groove does 0.1 to 30 times of corrugated plate thickness. Preferably, the depth of the liquid guide groove is 5 to 15 times of the thickness of the corrugated plate.

Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings. In the drawings, identical reference numbers indicate identical or functionally similar features.
FIG. 1 schematically shows a front view of a corrugated structured packing according to an embodiment of the present invention. The corrugated regular packing comprises corrugated plates and liquid guide grooves distributed on the surfaces of the corrugated plates. The extending direction of the corrugated plate's corrugated bodies is oriented obliquely with respect to the height direction of the corrugated plate. The corrugated body has a corrugation pitch angle alpha and smoothly transitions to the corrugation height direction, i.e. the vertical direction in the figure, towards both height ends of the corrugated plate. The liquid guiding grooves are distributed over the surface of the corrugated plate, and only a part of the liquid guiding grooves is exemplarily shown in fig. 1 to illustrate the position relationship between the liquid guiding grooves and the corrugations. It will be appreciated that each channel of the corrugated plate has the same extent and that once the liquid enters the channels it is directed in a uniform direction. As shown in FIG. 1, the width of the liquid guiding groove is significantly smaller than the corrugation width of the corrugated plate, so that there can be a plurality of starting points of the liquid guiding groove in one corrugation.
FIG. 2 schematically shows a front view of another embodiment of a corrugated structured packing according to the present invention. The difference with the embodiment of fig. 1 is that the corrugations in fig. 2 do not smoothly transition into the corrugation height direction of the corrugated sheet at both ends of the height, but extend at the same corrugation angle as the corrugated body. Furthermore, the channels in fig. 2 are also angled differently with respect to the corrugations. It will be understood, however, that the angle between the channels and the corrugations is not strictly dependent on whether the corrugations smoothly transition into the direction of the height of the corrugations at both ends of the height, and it is obvious that they may be designed and combined differently in other embodiments not shown.
FIG. 3 schematically showsbase:Sub>A cross-sectional view along the line A-A of the corrugated structured packing of FIGS. 1 and 2, in which the corrugations are seen inbase:Sub>A zigzag pattern and the channels are seen inbase:Sub>A concave-convex pattern distributed over the surfaces of the corrugations. Of course, in a cross-sectional view in this direction, the angular relationship between the corrugations and the channels and the orientation of the corrugations and the channels in the direction of extension are not shown.
Fig. 4 to 6 show schematically in partial perspective views different embodiments of the corrugated structured packing according to the invention. The channels may extend in unison with the corrugation orientation (fig. 4) or may extend within the corrugation but at an alternating angle to the corrugation (fig. 5). When the channels have a larger angle to the corrugations, the channels extend across a plurality of corrugations (fig. 6). In fig. 6, the angle β between the direction of extension of the flow channels and the direction of extension of the corrugated body is particularly clearly shown.
Fig. 7 and 8 schematically show processing blanks of different embodiments of corrugated structured packings according to the invention, wherein the liquid guide channel has been processed but no corrugations have yet been processed. The fluid sink in FIG. 8 has a different orientation than the fluid sink shown in FIG. 7.
In use, a plurality of corrugated structured packings standing parallel to each other are stacked face to form a packing tray (or block), wherein the corrugated inclination angles α of adjacent corrugated structured packings are opposite (i.e., symmetrical with respect to the height direction of the corrugated plates). Multiple layers of packing trays formed in this way are stacked up and down, and two adjacent layers of packing trays (or packing blocks) are stacked up and down in a staggered manner (namely corrugated structured packing is crossed due to different orientations). It is also possible to punch a plurality of small holes through the front and back surfaces of the corrugated structured packing to increase the fluid passage and mixing capacity.
