JPS599682Y2 - Filling plate for gas-liquid contact - Google Patents

Description

[Detailed description of the invention] The present invention relates to a packing plate for gas-liquid contact, commonly known as a liquid film type, which distributes liquid in a thin film form and brings it into contact with gas, and relates to a packing plate with good contact efficiency and high strength. .

In recent years, the quality of water used in gas-liquid contact devices such as cooling towers has deteriorated due to atmospheric pollution, etc., and the filling plates for gas-liquid contact used in these devices tend to have a large amount of scale, sludge, etc. attached, and are subject to heavy loads.

For this reason, there are many cases where the secondary rice filler plate buckles, reducing the area through which air passes, and reducing the gas-liquid contact efficiency.

Various studies have been made to increase the strength of the filling plate, but on the other hand, there are problems such as the need to increase the contact efficiency of the filling plate and the manufacturing and cost of the filling plate. A filled plate with high strength was not obtained.

The present invention solves the above problem, and consists of truncated pyramids formed in a plurality of vertical rows in each row on a plate material in which truncated cone-shaped convex parts and concave parts are alternately formed. It is characterized by slightly shifting the positions of the convex part and the four parts of the shape for each row, and forcing the neutral planes corresponding to the connection parts of the respective convex slopes and concave slopes to be pressed against each other, creating a discontinuous state. shall be.

The present invention will be explained below with reference to an example of implementation shown in FIGS. 1 to 3.

1 is a front view of the plate material according to the present invention, FIG. 2 is a right side view of FIG. 1, and FIG. 3 is a top plan view of FIG. 1.

In each figure, 1 is a plate material, 2 is a truncated pyramidal convex part, 3 is a concave part, 2' is a slope of the convex part 2, and 3' is a slope of the concave part 3, and these slopes 2', 3' is continuous and the boundary part corresponds to the original plate surface of the plate material 1, so the straight line part corresponding to this boundary part is assumed to be the neutral plane.

A matrix in which the convex portions 2 and concave portions 3 are vertically continuous is designated as A, B, C, and D columns in FIG. ′ and the neutral plane 4 a , 4 b , 4 C , 4 between the recessed slope 3 ′
Let d be mutually discontinuous.

In addition, in FIGS. 2 and 3, the convex part 2 and the concave part 3 are A2, A3 in A row, B2, B3 in B row, C2, C2 in C row,
Columns C3 and D are shown as D2 and D3.

Although the convex portions 2 and the recessed portions 3 illustrated above are only in the shape of a truncated quadrangular pyramid, a truncated pyramid shape or a truncated cone shape other than the quadrangular pyramid shape is also effective.

In the present invention, as described above, a plurality of plates are assembled into a multilayer structure, and the neutral plane of each plate, which corresponds to the boundary line between the convex portion and the concave portion of each row, does not continue in a horizontal straight line, but extends vertically #i. Since it is extremely discontinuous, when a load is applied, the parts where the load is concentrated are dispersed, so there is no concentrated load, and there is no risk of buckling due to concentrated loads, resulting in good ventilation. It can withstand use and is suitable as a gas-liquid contact filling material for cooling towers, gas absorption towers, dehumidification towers, gas generation towers, etc., and also as a filling material for wastewater treatment such as sprinkler beds, fixed filter beds, and rotating disks. It is also applicable as
