Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling tower for efficiently cooling hot water discharged from factory equipment, air conditioning equipment and the like.

[0002]

2. Description of the Related Art Conventionally, a cooling tower used to cool and circulate hot water discharged from factory equipment, air-conditioning equipment such as buildings, and the like has been used for cooling hot water. From the viewpoint of the method, there are a so-called "cross flow method" in which hot water and a cooling air flow intersect at a right angle, and a so-called "counter flow method" in which hot water and a cooling air flow face each other. The structure of the louver partitioning part can be applied to any type of cooling tower. Therefore, in order to facilitate understanding of the present invention, as an example, FIG. 4 shows a schematic configuration of a cross-flow type cooling tower. In the figure, filler blocks 2 and 2 are installed on both sides of a ventilation space 1, and a cooling fan 3 is provided above the ventilation space 1.
Is attached and a hot water distribution tank 4 is provided above each filler block 2, and hot water is supplied to the hot water distribution tank 4 from a hot water supply pipe 5 through a sprinkler box 6. A large number of small holes 7 are formed on the bottom surface of each hot water distribution tank 4, and hot water is supplied to the filler block 2 through the small holes 7, and the supplied hot water flows down through the filler block 2. . On the other hand, the louver 8 on the side of the filler block 2 is cooled by the cooling fan 3.
A flow F of air is generated toward the ventilation space 1 through the filling material block 2, and the hot water flowing down in the filling material block 2 is cooled by the air flow F. Then, the air after heat exchange with the hot water is separated into water droplets by the eliminator 9,
It is released to the outside. As described above, in the cross-flow type cooling tower, the warm water flowing down is cooled by the airflow supplied from the lateral direction. Thus, the hot water that has passed through the filler block 2 becomes cold water and is stored in the cold water tank 10.

As described above, the cross-flow type cooling tower is
The hot water flowing down through the packing material block is cooled by the air sucked from the louvers on the side of the tower, and this cooling tower is generally composed of a plurality of chambers (cells). The cooling tower shown consists of 5 cells, 3a
Indicates a fan stack. The boundaries of the cells in the cooling tower are often partitioned by partition walls, and at that time, it is customary to partition the louvers 8 on the sides to prevent the movement of water between the cells. This is because if there is water movement between cells via the louver part, the water surface level of the cold water tank 10 cannot be controlled, and in the cell in which water flows out, depending on the amount of water flowing out, cold water will be sent. This is because it may interfere with the operation of the circulating pump that supplies water, and in the cell into which water flows in, there is a problem that the inside of the tower cannot be cleaned even when the operation of the cell is stopped. Therefore, as shown in FIGS. 6 to 8, the conventional louver partition portion is welded to the partition column 11 by welding the arm 1
2 is attached, the partition plate 13 is interposed between the arms 12 which are vertically adjacent to each other, and the louver 14 is placed on the arms 12.
The insert 15 is arranged so as to sandwich the louver 14, and the insert 15 is pressed by one side 16b of the mountain-shaped pressing plate 16 in which one side 16a is attached to the partition plate 13, and the one side 16b of the pressing plate 16 by the fastening member 17. Tighten the insert 15, the louver 14 and the arm 12 so that the insert 15 and the arm 12 are in close contact with each other.
8 has a structure in which the movement of water between cells in the louver portion can be eliminated.

The conventional method for constructing the louver partition of the above-mentioned structure is that only the welding of the arm bar 12 to the partition column 11 is prefabricated in the factory, and all the other structural members are attached by on-site assembly work. It is being appreciated. Therefore, the number of man-hours for mounting the partition plate on the site where the cooling tower is installed is large, and the structure is complicated, so that the finish condition is easily influenced by the skill level of the operator. Further, depending on the finished state, it may not be possible to prevent the movement of water between the cells of the louver portion.

The present invention has been made in view of the above problems of the prior art, and an object thereof is a structure capable of reliably preventing the movement of water between cells in the louver portion, and the on-site. It is an object of the present invention to provide a cooling tower having a louver partitioning structure whose construction is relatively simple and whose finished state is not affected by the skill level of a worker.

[0006]

To achieve the above object, a cooling tower of the present invention comprises a hot water distribution tank for supplying hot water above a packing material block, and a cold water tank below the packing material block. In a cooling tower composed of a plurality of cells for cooling hot water flowing down in a material block by an air flow passing through a louver provided on a side, a partition part for partitioning the louver at the boundary of each cell has the following structure. . That is, in the cooling tower according to the present invention, the partition plates and the arms are alternately attached to the partition columns in the longitudinal direction of the column so that the partition plates and the arms are protruded, and the louver ends and the arms mounted on the arms are fastened. The louver partition has a structure in which it is fastened by members.

[0007]

[Operation] A simple structure in which partition plates and arms are alternately attached along the longitudinal direction of the partition column, the louver end is placed on the arms, and the arm members are fastened to the arms by fastening members, so that the factory If the partition plate and arms are attached to the partition pillar by welding, etc., the assembly work of the louver partition part where the cooling tower is actually installed is done by mounting the louver end on the arm bar of the partition pillar fixed in place. All you have to do is put it on and tighten it.

[0008]

EXAMPLES Examples of the present invention will be described below. Since the cross section of the cooling tower body is the same as that shown in FIG. 4, the description thereof is omitted, and the structure of the louver partition section will be described below with reference to FIGS.
Will be described with reference to. 1 is a perspective view of a louver partition, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a view taken along the line III-III of FIG. As shown in the figure, in the longitudinal direction of the partition column 11, the arms 12 and the partition plate 13 are alternately attached by welding so that the arms 12 and the partition plate 13 are projected, and the end of the louver 14 is placed on the arm 12 and the end of the louver 14 is attached. This is a structure in which the arms 12 are fastened by fastening members 17. In addition, the welding of the partition 11 and the arm 12 and the partition plate 13 is performed in the factory, and the construction on site is
Only the fastening work with the fastening member 17 was performed.

Although the present embodiment is applied to the cross-flow type cooling tower, the present invention is not limited to this type, and as described above, can be applied to the counter-flow type cooling tower.

[0010]

Since the present invention is configured as described above, it has the following effects. Installation work of the louver partition in the field where the cooling tower is installed becomes simple. Therefore, the finished state of the louver partition section is less likely to be affected by the skill level of the operator. As a result, there is no movement of water between cells in the louver partition.
