Fig. 1-Fig. 2 is a kind of mesh-type structured packing that the utility model embodiment provides, including 10 He of multiple filling layers layer
Fixing device 20, the distribution stacked on top of one another in the horizontal direction of multilayer described filler layer 10, the fixing device 20 will fill out described in multilayer
The bed of material 10 is fixed together, every layer of described filler layer 10 spliced by multiple packing elements 11 for being vertically arranged in same level and
Be inner hollow and the truncated cone-shaped of both ends open into, the packing element 11, and its outer diameter it is larger one end it is downward, every layer multiple
11 rectangular array of packing element distribution, and lower end 11 side of packing element adjacent thereto of each 11 side of packing element
Lower end it is circumscribed and be connected, form gap between four adjacent packing elements 11 of same layer, two layers of arbitrary neighborhood it is each
Described filler layer is staggered about 10.
In above-mentioned technical proposal, as shown in Fig. 2, by the way that packing element 11 is arranged to up-small and down-big truncated cone-shaped, then will be more
A packing element 11 is spliced into packing layer 10, can increase the specific surface area of packing layer 10, while reduces resistance；Multiple packing elements 11
Rectangular array is distributed, and lower end 11 side of packing element adjacent thereto of each 11 side of packing element lower end it is circumscribed and
It is fixedly connected, packing layer 10 can be used integrated molding and be made or when packing element 11 is metal material, using welding
Multiple packing elements 11 are fixedly connected by mode, and the vertex of such four packing elements 11 is located at a length of side and is equal to packing element 11 respectively
On four vertex of the square of radius, gap is formd between this four packing elements 11, then by two adjacent packing layers 10
It is staggered, you can the inner cavity connection of packing element 11 on the packing layer 10 for making the gap on arbitrary packing layer 10 adjacent thereto, greatly
The earth enhances turbulent flow of the gas-liquid two-phase logistics between packing layer 10 so that gas-liquid two-phase mixing is abundant, further promotes gas
The mass transfer and heat transfer efficiency of liquid two-phase, and pass through fixing device 20 and multiple filling layers layer 10 is fixed together.
As shown in figure 3, in the mesh-type structured packing, on the side wall of each packing element 11 interval be provided with it is more
A through hole 12.
In another technical solution, for the voidage of mesh-type structured packing, it is spaced apart on each packing element 11
There are multiple through holes 12, you can the voidage of enhancing mesh-type structured packing improves the mass-and heat-transfer efficiency of gas-liquid two-phase.
In the mesh-type structured packing, multiple through holes 12 on each packing element 11 circumferentially uniformly between
Every distribution.
In another technical solution, multiple through holes 12 are equidistantly arranged at intervals, can cause mesh-type structured packing

22, multilayer described filler layer 10 is fixed together.
In another technical solution, the fixing means of conventional packing layer 10 is monolithic filler by the way of flanging
It is fixed up, when a certain packing layer 10 damages, it is impossible to it is replaced, structured packing can only be given it up, and it is our
In case, by the more screw rods being vertically arranged 21, screw rod 21 is set through multiple filling layers layer 10, then is pacified respectively at 21 both ends of screw rod
Equipped with matched nut 22, by tightening nut 22, nut 22 and packing layer 10 are inconsistent, and multiple filling layers layer 10 is fixed on one
Rise, and need to a certain packing layer 10 carry out replace be, it is only necessary to nut 22 is unclamped, screw rod 21 is removed, damage is filled out
After the bed of material 10 is replaced, nut 22 is being tightened, multiple filling layers layer 10 is being fixed together.
As shown in Figs. 1-3, in the mesh-type structured packing, any one of sky in every layer of described filler layer 10
The central point of gap is located in one layer of described filler layer 10 adjacent thereto on the axis of the corresponding packing element 11, the screw rod
21 are set along the axis of any one packing element 11 of wherein one layer described filler layer 10.
In another technical solution, multiple filling layers layer 10 is staggered, adjacent two packing layers 10 are staggered,
Packing element 11 on two packing layers 10 at interval, which corresponds, to be set, in adjacent two packing layers 10, any one gap
Central point be located on packing layer 10 adjacent thereto on the axis of corresponding packing element 11, material is thus formed packing element 11-
The structure in gap-packing element 11- gaps forms connection, and is evenly distributed, and improves the stability of structured packing, further carries
The mass-and heat-transfer efficiency of high gas-liquid two-phase, and screw rod 21 is set along the axis of a certain packing element 11, i.e., it is empty through packing element 11-
The passage that the structure in gap-packing element 11- gaps is formed.
In the mesh-type structured packing, each circular ring shape is provided between the nut 22 and described filler layer 10
Gasket 23, the gasket 23 are set on the corresponding screw rod 21, and its outer diameter is more than the outer diameter of 11 upper end of packing element.
In another technical solution, in order to make the fixation between nut 22 and packing layer 10 more firm, in nut 22
The gasket 23 of circular ring shape is provided between packing layer 10, increases the contact area between nut 22 and packing layer 10, reduces pressure
Power protects nut 22 and packing layer 10, simultaneously because screw rod 21 is set along the axis of a certain packing element 11, needs through multiple
Packing element 11 and multiple gaps, needs are abutted with the upper end of the packing element 11 of the top, so needing the outer diameter of gasket 23
It is set greater than the outer diameter of 11 upper end of packing element.
