The size of each of the blocks 101 constituting the material 102 is determined such that in the stage of each material 102, joint surfaces 115 of the blocks 101 are biased between parallelly adjoining blocks 101 and also angularly spaced a predetermined angle, whereby the joint surfaces 115 of the blocks 101 are prevented from overlapping each other between adjoining materials 102.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a material and / or packing material for a heat exchange tower.

[0002]

2. Description of the Related Art Heretofore, packing materials for gas-liquid contact have been used in heat exchange towers and / or substances such as distillation towers, absorption towers, cooling towers used in the chemical industry. As shown in FIG. 4, for example, such a filler generally forms a sheet-like base material 10 creased with respect to the tower axis along the tower axis,
That is, they are stacked upright so that the folds are alternately crossed. When operating the exchange tower,
The liquid flows down from the top of the tower, the gas rises from the bottom, and the respective streams are brought into contact with each other in a state of being uniformly distributed over the entire cross-sectional area of the tower by the surface of the sheet-like base material. And exchange material.

When the exchange tower in which the filler is installed is relatively small, a plurality of sheet-like base materials are laminated and formed into a shape corresponding to the cross section (usually circular) of the exchange tower. To form a cylindrical laminated structure that can be inserted therein. When the tower is relatively large, first, a sheet-like base material 10 is laminated as shown in FIG. 4 to form a rectangular filler block 11, which is then exchanged as shown in FIG. It is often performed to arrange a plurality of such filters in a tower so as to be formed in a shape conforming to the cross section (usually circular) of the column. For example, in the embodiment shown in FIG. 5, two filler blocks 11 are arranged in a series direction and a plurality of the filler blocks 11 are arranged in a parallel direction, and are combined so as to have a cylindrical shape as a whole. Alternatively, if the tower is larger, for example, as shown in FIG.
May be combined in a row in the direction of three or more.

[0004] When the height of the tower is large, a plurality of structures 12 formed by a collection of such filler blocks 11 are often stacked in the vertical direction. In this case, as shown in FIG. 5 or FIG. 7, the arrangement of the filler blocks 11 is changed, for example, by 90
゜ It is preferable to rotate the joint so that the joints of the filler blocks in the structures do not match between the vertically stacked structures. This is because when the liquid flows down from above, the liquid easily flows along the seam of the filler block, and if the seam coincides between the upper and lower composite structures, the liquid flow will follow the seam. Because it flows preferentially, and a uniform liquid flow distribution over the entire cross-sectional area of the column is hindered.

[0005] This phenomenon of preferential flow of the liquid flow along the seam is more pronounced than the seam on the sheet surface of the filler block.
It becomes a big problem at the joint of the joint surface. In addition, in this specification, the "sheet surface of a filler block" means the surface in which the surface of the outermost sheet base material is arranged in the filler block, and "the joining surface of the filler block".
"" Means a surface on which the end of each sheet base constituting the filler block is arranged. That is, in FIG.
The surface indicated by 5 is the “joining surface of the filler block”,
The surface indicated by 16 is the “sheet surface of the filler block”. The above problem occurs because the surface of the sheet substrate (which is formed into a corrugated shape) is arranged on the sheet surface of the filler block, so that even if the liquid flow is collected on this surface, the sheet substrate On the other hand, at the joint surface of the filler block, the ends of the respective sheet bases constituting the block are arranged, so that the liquid flows along the edges. Is likely to flow down straight down.

[0006]

In view of this phenomenon,
As shown in FIG. 5, the aggregate 12 of the filler blocks 11
Are stacked with a rotation of, for example, 90 ° between the upper and lower assemblies. That is, the seam of the joint surface 15 of the filler block always has a portion overlapping between the upper and lower aggregates. This will be described with reference to FIG. FIG.
FIG. 3 is a conceptual diagram of the aggregate 12 of the filler blocks 11 as viewed from above, where a thick solid line represents a bonding surface 15 of each filler block, and a thin solid line represents a sheet surface 16 of each filler block. As shown in FIG. 6a, the upper and lower filler block assemblies 12 are
゜ When rotated and stacked, they are arranged as shown in FIG. 6b. Here, the solid line represents the seam of the filler block in the aggregate arranged above, and the broken line represents the seam of the filler block in the aggregate arranged below. From FIG. 6b,
It can be seen that the seam of the joint surface 15 of the filler block overlaps at one central point between the upper and lower assemblies (indicated by a circle 20 in the figure). As described above, if there is a portion where the seam of the joint surface of the filler block overlaps between the upper and lower aggregates, the liquid flow concentrated on this seam flows straight downward without being dispersed outside, and The uniform distribution of the liquid flow throughout is impaired.

[0007] This problem similarly exists in an aggregate in which three or more filler blocks are arranged in series as shown in FIG. FIG. 8 shows an arrangement of seams when the filler block aggregate as shown in FIG. 7 is rotated by 90 ° and stacked vertically. The thick line, the thin line, and the broken line have the same meaning as in FIG. From FIG. 8b, it can be seen that, in the filler block aggregate having such an arrangement, there are four portions where the joints of the joining surfaces of the filler blocks overlap each other between the upper and lower aggregates (circles in the figure). 20). FIG. 9 shows an arrangement of seams when the filler block aggregate as shown in FIG. 7 is rotated by 45 ° and stacked vertically. From FIG. 9b, it can be seen that even when rotated by 45 °, there are four portions where the joints of the joining surfaces of the filler blocks overlap (indicated by circles 20 in the figure).

[0008] As described above, in the packing block assembly of the prior art, no attention is paid to the state of the overlap of the joints of the filler block joining surfaces between the upper and lower packing block assemblies. In the above operation, the liquid flow concentrates on the portion where the joint of the filler block joining surface overlaps, which may cause a situation in which uniform contact between gas and liquid cannot be achieved.

[0009]

As a result of repeated studies to solve such problems in the prior art, the present inventor has found that at each of the filler block aggregates, the joint surface of the filler blocks is formed. When the size of each filler block is appropriately selected so that the seam is deviated between the adjacent filler blocks in the parallel direction, the filler blocks are rotated to have a predetermined angle and stacked vertically. The inventors have found that it is possible to prevent a portion where the joint of the filler block joining surface overlaps from occurring between the aggregates, and have completed the present invention.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS That is, the present invention relates to a method of supplying a liquid from above and a gas from below, and bringing the gas and liquid into contact with each other so that the substance and / or heat exchange between the two substances can be performed inside the column. A tower packing structure to be installed, wherein the packing structure comprises a plurality of continuous creased sheet substrates inclined with respect to the axis of the tower such that the creases intersect each other. A plurality of filler blocks formed by stacking a plurality of filler blocks along the axis of the filler block arranged in series and in parallel, and stacked in a plurality of stages in the vertical direction. The steps of the filler block assembly are stacked one above the other by rotating them at a predetermined angle, and the size of each filler block constituting the filler block assembly is determined by the size of each filler block. At the stage of the assembly, the joints at the joint surfaces of the filler blocks are deviated between the adjacent filler blocks in the parallel direction, and the fillers are stacked vertically by rotating so as to have a predetermined angle. The present invention relates to a packing material for a tower, characterized in that it is determined that there is no place where the seams of the bonding surface of the packing material block overlap each other between the stages of the block assembly.

Hereinafter, the concept of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an example of an aggregate 102 of filler blocks 101 arranged according to the present invention. Each rectangular body represents a filler block 101 formed by laminating a plurality of sheet-like base materials as shown in FIG. The filler block aggregate 102 according to the present invention includes the filler blocks 1 that are arranged in series.
The size of each filler block is determined so that the seam of the joint surface 115 between the first and second filler blocks is displaced between the adjacent filler blocks in the parallel direction.
For example, in the embodiment shown in FIG. 1, it will be understood that the seams of the filler block joining surfaces are arranged stepwise in the parallel direction.

As shown in FIG. 1, the arrangement of joints when the filler block assembly 102 thus configured is rotated by a certain angle and stacked vertically is shown in FIGS. FIG. 2 shows the upper and lower filler block aggregates 102.
FIG. 3 shows the arrangement of the seams when they are stacked by rotating them 90 °, and FIG. 3 shows the arrangement of the seams when they are stacked by rotating the upper and lower filler block assemblies 102 by 45 °. In each figure, bold, thin and dashed lines
As in FIG. 6 and the like, the joining surface 1 of the filler block
15 represents the seam of the filler block, the seam of the sheet surface 116 of the filler block, and the seam of the filler block disposed below. From FIG. 2b, the joining surface 115 between the filler blocks
By appropriately selecting the deviation of the joints of the filler blocks, there is no place where the joints of the filler block joint surfaces overlap each other between the filler block assemblies 102 which are rotated 90 ° and stacked one above the other. We can see that we can do it. Further, referring to FIG. 9B, even when the filler block aggregate 102 is rotated by 45 ° and stacked vertically, the filler block joint surface 115 is formed between the vertically stacked filler block aggregates 102. It can be seen that there can be no overlapping portions of the seam.

The filler block assembly 102 according to the present invention
In the laminated structure of the above, the seam of the filler block joining surface 115 in each step does not overlap between the upper and lower aggregates 102, so that the filler block joining Even if the liquid flow concentrates on the seam of the surface 115, the concentrated liquid flow is guided immediately above the sheet-like base material constituting the filler block in the next step, so that the liquid flow along the surface of the sheet-like base material Dispersion, which eliminates non-uniform distribution of the liquid flow and achieves a uniform liquid flow distribution over the column cross section.

In the filler structure according to the present invention, the degree of deviation of the seam of the joint surface 115 of the filler blocks in each filler block assembly and the rotation angles of the upper and lower filler block assemblies are different. It can be appropriately determined that there is no place where the joints of the filler block joining surfaces 115 overlap each other between the filler block aggregates 102 stacked vertically.

[0016]

As is apparent from the above description, the present invention relates to a filler block joining between upper and lower filler block assemblies, which has been completely unattended in the prior art. It focuses on the state of overlap of the seam of the surface, and by eliminating the overlap of the seam of the joint surface of the filler block, during the operation of the exchange tower, the part where the seam of the joint surface of the filler block overlaps It is possible to prevent a situation in which the liquid flow is concentrated and uniform contact of gas and liquid cannot be achieved, and a very uniform liquid distribution can be achieved over the entire column.
