Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary packing connected to a grid-like packing (hereinafter simply referred to as "grid") used in a gas-liquid contact tower such as a cooling tower or an absorption tower, and particularly relates to The aim is to improve heat or mass transfer performance by increasing the

BACKGROUND ART Conventionally, injection molded products made of synthetic resin as shown in FIGS. 1 and 2 have been known as grids.

When these grids are packed into the column body of a gas-liquid contact tower, the above required performance is achieved by changing the gas-liquid contact area, pressure loss, etc. in order to satisfy the required heat or mass transfer performance. Various filling methods are used.

In other words, in order to maximize the heat or mass transfer performance, as shown in Figure 3, if the single grids are stacked and packed in multiple stages with no spacing between them, and are alternately shifted by 90 degrees, the The gas-liquid contact area becomes maximum.

In addition, when filling is carried out by placing the column on the support part B protruding from the inner circumferential wall of the tower body A at a required interval as shown in Fig. 4, the larger the interval, the more gas and liquid per unit volume. Although the contact area is reduced, the pressure drop is also reduced.

In this case, since a support part was required, the manufacturing cost was high and the filling operation was also very troublesome.

For this reason, when it is necessary to further improve the heat or mass transfer performance of the conventional grid, it must be replaced with a new grid with a larger gas-liquid contact area, which is extremely wasteful.

This invention eliminates such waste, and without discarding conventional products, it is possible to create a large number of cross-shaped, square-shaped, etc. projections on both or one side of the lattice surface, that is, the upper and lower end surfaces of the lattice. The gas-liquid contact area can be increased with a very simple operation by appropriately connecting the auxiliary packing formed with the auxiliary packing, and the desired heat or mass transfer performance can be obtained.

The present invention will be explained below with reference to examples shown in the accompanying drawings.

In Figures 5, 6 and 7, reference numeral 1 is an auxiliary filling made of synthetic resin, etc., for example, horizontal bones 2 are arranged parallel to each other at equal intervals, and vertical bones 2 are arranged in parallel at right angles to the horizontal bones 2. Bone 3 is integrally connected.

Protrusions 4, 4l having a cross-shaped cross section as shown in the figure are formed on both the upper and lower parts of the orthogonal part between each horizontal bone 2 and the vertical bone 3, that is, on the lattice surface side, and around each protrusion 4, 4', a normal simple Notches 5 and 5l are provided so as to be able to engage and connect to one grid, and the outline of its structure is most clearly seen from the perspective view shown in FIG.

However, the auxiliary filler is not limited to such a structure; the cross-shaped protrusion may be provided only on one side, or the protrusion may be formed into a cross-sectional shape such as a square cross-section. The key is to be able to connect to a single regular grid.

9 and 10 show a plan view and a side view of a single grid 10 connected to each other by an auxiliary filler having cross-shaped projections on both sides of the grid surfaces shown in FIG. 8.

In this case, as is clear from FIG. 10, the relationship between the depth of the cuts made on both the upper and lower sides from the end face of the grid surface of the auxiliary filling and the height of the bone plate of a normal single grid is t1≦t4, t3
It is necessary to satisfy the condition ≦t5, and there is no particular restriction on t2.

11 Furthermore, if t1≦/2t4, 13≦/2t5, it becomes possible to alternately stack and connect the single grid and the auxiliary grid.

Further, when 73=0, the protrusion is formed only on one side of the grid surface, which is suitable for connecting to the bottom grid or the top grid.

According to the present invention configured as described above, an auxiliary grid having a large gas-liquid contact area can be extremely easily connected to a single ordinary grid, and the gas-liquid contact efficiency can be improved.

Furthermore, by connecting the auxiliary filler, the strength against loads such as lateral or compressive loads is greatly increased.

Furthermore, the grid supporting part, which was conventionally provided protruding from the inner peripheral wall of the tower body, is no longer required, making manufacturing and filling operations easier.
