Description

[Detailed Description of the Invention] The present invention relates to a so-called droplet-type lattice-shaped filler that makes liquid droplets come into contact with gas.

Conventionally, as a lattice-shaped packing material used in gas-liquid contact devices, a rectangular lattice-like packing material in which vertical members T and horizontal members Y are arranged roughly, as shown in Fig. 5, or vertical members T and horizontal members Y as shown in Fig. 6, has been used. A square lattice structure in which the materials Y are combined in a square shape is used, but these have the following drawbacks.

That is, regardless of whether it is rectangular or square, since the grid portion is linear, the surface area that droplets hit is small, and the formation of droplets is not sufficiently achieved, resulting in poor gas-liquid contact efficiency.

For this reason, for example, as shown in JP-A-51-126970, a filling material is constructed by making horizontal cuts in a flat plate and folding them alternately in a zigzag pattern to form a contact surface, and then assembling this into a frame plate. There are known products with enhanced gas-liquid contact effects.

However, even in this filling material, the contact efficiency is not sufficient because the liquid extraction contact surface is only one surface in each stage.

In order to eliminate the above-mentioned drawbacks, the present invention uses a large number of vertical lattice materials whose contact surfaces are alternately bent in the horizontal plane, alternately inclined in the vertical direction, and vertically symmetrical about the horizontal central axis. This relates to a lattice-shaped packing material arranged in parallel, which increases the dispersion of droplets and the contact area of the droplets, thereby increasing the efficiency of gas-liquid contact.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a perspective view of a lattice-shaped filling material according to the present invention, where 1 is a vertical lattice material and 2 is a horizontal lattice material.

FIG. 2 is a partially enlarged perspective view of the vertical lattice material 1 in FIG. slope 1a
, lb, and are vertically symmetrical about the horizontal central axis CL. Therefore, the bends of the upper edge 1C and the lower edge 1d are alternately shifted, resulting in a significantly wider contact area.

3 and 4 are end views showing another embodiment of the bending mechanism of the present invention, and the slope of the contact surface is similar to the embodiment shown in FIGS. 1 and 2, and the upper and lower edges are Fig. 3 shows an embodiment in which the vertical lattice members 1 are bent in a sine curve shape, and Fig. 4 shows an embodiment in which the vertical lattice members 1 and the horizontal lattice plates 2 are bent in a sine curve shape. An example of bending in a curved shape is shown.

Note that the method for manufacturing the lattice filling material is to assemble it by making notches in a bent plate-shaped body, or to assemble
It is integrally formed using a thermoplastic resin such as VC by means such as injection molding.

Since the present invention is a lattice-like filling material having the structure as described above, it has the following advantages.

That is, in the present invention, a large number of vertical lattice members are arranged side by side, the contact surfaces of which are alternately bent in the horizontal plane and alternately inclined in the vertical direction, and which are vertically symmetrical about the horizontal central axis. Each stage has sloped surfaces in multiple directions, so the area that falling water droplets come into contact with increases significantly, resulting in more collisions of water droplets and further promoting the formation of droplets.The sloped surfaces also disrupt the gas flow. There are various advantages such as further increasing the efficiency of gas-liquid contact.
