Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a filler block for a cooling tower, and more particularly to a filler block used in a crossflow closed white smoke prevention type cooling tower having a dry section for preventing white smoke. Manufacturing method.

[0002]

2. Description of the Related Art Cooling towers, which are operated in the winter when white smoke is likely to be generated, are often used in important facilities such as computer rooms. Therefore, circulating water may be contaminated by direct contact with air. The adoption of no closed cooling towers is increasing. As this closed cooling tower, heat exchange coils forming a closed circuit for flowing cooling water (process water) are arranged in multiple stages, and a laminated film type for cooling spray water between the heat exchange coils. A method of arranging a filler is often used.

On the other hand, when white smoke is generated from the exhaust port of the cooling tower, it may be mistaken for the outside air to be contaminated or may be mistaken for a fire. There has been proposed a structure for preventing the generation of white smoke by using a dry-wet mixing type filler in which a passage for exclusive use of air, a so-called dry type portion is provided in a part of the laminated type wet filler.
-75459). Therefore, by applying this dry / wet mixed type filler to the laminated film type filler of the closed cooling tower, it is possible to prevent the generation of white smoke by lowering the humidity of the discharged air even in the winter operation.

[0004]

However, the dry-wet mixing type filler has a substantially flat plate-shaped wet portion for each filler block, that is, a portion where the cooling water flowing down and the cooling air directly contact each other. A tunnel-shaped dry type part, that is, an air-only passage in which air from the air inlet flows without contact with cooling water,
It is manufactured by repeatedly laminating and adhering or welding in a predetermined order. For this reason, when the height of the filler block needs to be about 100 mm, and sometimes about 50 mm, such as the filler for the hermetic cooling tower inserted between the heat exchange coils, its manufacture is extremely difficult. It was troublesome. That is, as described above, in the work of stacking the wet part and the dry part to manufacture a small filler, it is difficult to obtain an accurate stacked state even if an appropriate jig is used, and the entire cooling tower is also manufactured. The number of times of stacking the filler to be filled in was considerably large, and the labor was also great.

Therefore, the present invention is directed to a crossflow closed cooling tower.
A small filler with a height of 100 mm or less can be easily and
An object of the present invention is to provide a manufacturing method of a cooling tower filler block that can be manufactured at low cost.
