Description

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 the dry / wet mixed type filler to the laminated film type filler of the closed type 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, the work of stacking the wet part and the dry part to produce a small filler is difficult to obtain an accurate stacked state even if an appropriate jig is used. 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 provides a manufacturing method of a cooling tower packing material block which can easily and inexpensively manufacture a small packing material such as a packing material for a closed cooling tower. It is an object.

[0006]

In order to achieve the above-mentioned object, the method for producing a cooling tower packing block of the present invention comprises:
After a tunnel-shaped dry portion having a size of a plurality of blocks and a plate-shaped wet portion having a size of a plurality of blocks are laminated and joined in a predetermined order, the laminated body is made into a size corresponding to each block. It is characterized by cutting into pieces.

[0007]

[Operation] According to the above configuration, since cutting is performed after stacking a plurality of blocks, the number of stacking steps when manufacturing one cooling tower can be significantly reduced, and since large materials are handled, handling is easy. It becomes easier and the dimensional accuracy can be improved.

First, an outline of the closed crossflow type cooling tower will be described with reference to FIG. In this closed cross-flow cooling tower, an exhaust port 3 having a fan 2 is provided at the center of the upper part of a main body 1, air intakes 4 are provided on both sides of the main body, and heat of process water flowing inside the air intake 4 is provided. An exchange coil 5 and a filler block 7 for cooling the sprayed water sprayed from the upper sprinkler 6 are alternately arranged in multiple stages. The sprayed water is supplied from the bottom of the tower to the top of the tower via a pump 8. The process water is circulated in the water sprinkling section 6 of the above, is introduced into each heat exchange coil 5 from the pipe 9, is cooled, and is then led out of the pipe 10.

Next, a procedure for manufacturing the filler block 7 will be described. First, in the manufacturing method shown in FIGS. 1 to 3, a plate-shaped wet part constituent member 11 having a size corresponding to a plurality of blocks and a dry part constituent member 12 provided with a tunnel-shaped dry part 12a corresponding to a plurality of blocks are provided. And are overlapped with each other in a predetermined order, and they are repeatedly bonded or welded to each other through the projections 13 for holding a gap, which are integrated,
The obtained laminate is cut along a cutting line C passing through between the dry parts 12a of the dry part constituting member 12, and as shown in FIG.
The filler block 7 is manufactured by laminating 1a and the dry part 12a at a predetermined interval and in a predetermined order. The space-holding projections 13 may be integrally formed, or separate members may be joined together.

The dry type component 12 in this embodiment is
As shown in FIG. 3, plate members formed in a predetermined corrugation for forming the dry portion 12a and the sealing portions 12b on both sides of the dry portion 12a are faced to each other and the sealing portions 12b are bonded to each other by adhesion or welding. By doing so, the dry type component member 12 can be handled in the same manner as the wet type component member 11, and the laminating process can be greatly simplified.

The manufacturing procedure shown in FIGS. 5 to 7 uses the dry type component member 21 having the shape shown in FIG. 7 as the dry type component member. The dry part forming member 21 is formed by bending a plate material having a predetermined shape from one sealing part 21b.
1a is formed, and the other overlapping portion 21c is joined as necessary, and when it is left as it is, the overlapping portion 21c is arranged so as to face a certain direction.

One of the wet parts uses a wet part constituting member 11 which is substantially the same as that of the above-mentioned embodiment. In this embodiment, similarly to the above, two wet part constituting members 11 are superposed and joined to each other, and then a predetermined part is formed.
