FIG. 1 shows the structure of a general mechanical ventilation cooling water tower. Briefly explaining this, hot water a is sent to a water spray header 1 by a pump and sprayed from a top to a packed bed 3 by a nozzle 2. There, the bottom water tank 6 is cooled by being countercurrently contacted with the rising outside air sucked into the tower 5 by the blower 4 and cooled.
It is designed to be stored in.

ことが望ましい。
By the way, the outside air sucked and rising in the tower 5 is
In order to improve the contact efficiency with water, it is desirable to guide the particles uniformly to the packed bed 3.

However, since the intake air distribution to the cold water tower 5 is based only on the rectifying action by the louver 7, it is not sufficient to evenly distribute the air to the packed bed 3 horizontally arranged on the upper surface of the louver 7, and especially on the outer wall side. In the filling layer 3, there is a dead area D in which the outside air b cannot be taken in at all, as indicated by the shaded area in the figure. This dead area D becomes more remarkable as the cooling tower becomes larger, which causes the cooling capacity of the tower to be insufficiently exhibited.

In order to achieve the above-mentioned object, the present invention is to spray hot water from the upper part to the packed bed and bring it into countercurrent contact with the outside air introduced from the lower side wall and sucked up in the packed bed to cool the warm water and store it in the bottom part. In the cold water tower, the packed bed is partitioned in the radial direction and divided into a plurality of packing chambers, and the outside air introduced from the lower side wall is distributed and guided into these packing chambers and descends from the packed bed. It is characterized in that a guide plate which allows passage of water is provided. This allows outside air to be taken into the packed bed in a uniform state,
This is to prevent the uniform air distribution in the packed bed from becoming insufficient and from causing a dead area.

On the other hand, in order to make the air distribution in each of the filling chambers 8 uniform in the space formed between the bottom water tank 6 of the packed bed 3 and each of the filling from the louver 7 surface provided on the outer wall of the lower part of the tower. Room 8
The guide plates 10 reaching the lower part are provided in multiple stages to guide the outside air sucked from the louver 7 into each filling chamber 8. The guide plate 10 is composed of an inclined portion 11 and a vertical portion 12 continuous with the inclined portion 11, and the vertical portion 12 is the airflow partition plate 9
The inclined portion 11 is adapted to allow the water falling from the packed bed 3 to pass therethrough. As the means for allowing water to pass, the example shown in FIG. 3 shows the simplest and surest method of forming a large number of water passage holes 13 in the inclined portion 11 of the guide plate 10. Similarly, in the example shown in FIG.
Instead of providing

The operation of the present embodiment having the above-described configuration will be described. The outside air b sucked into the tower 5 from the louver 7 by the blower 4 is first divided by the plurality of guide plates 10 facing the louver 7 surface and separated from each guide plate 10. It is guided inward in the radial direction along the inclined portion 11 and air is distributed in the radial direction. Then, the outside air distributed in the radial direction hits the vertical portion 12 of the guide plate 10 to change its course and rises, and is guided into each filling chamber 8 connected to each vertical portion 12. Then, the hot water is countercurrently contacted with the hot water that is sprayed from the nozzles 2 and drops in each filling chamber 8, and the hot water is cooled and then discharged from the air outlet of the blower 4. In this case, the guide plate 10 and the filling chamber 8
Since the air flow partition plate 9 forming the above forms an independent outside air passage and restricts the entry into the adjacent passages, the Since there is a large deviation from the axial center of the blower 4, there is a large tendency for the external airflow to become lean, but even in that case, air can be evenly distributed to each filling chamber 8. Therefore, the gas-liquid contact in the packed bed 3 can be enhanced and the cooling efficiency of the hot water can be improved.

On the other hand, the water cooled by gas-liquid contact in each filling chamber 8 passes through the filling layer 3 and drops onto the inclined portion 11 of the guide plate 10, but the inclined portion 11 has a water passage hole 13 or a gap. Since the guide plate 10 is provided, the inclined portion 11 is not blocked by the guide plate 10.
Water is allowed to pass through the water passage holes 13 or the gaps 14 in the process of fluidizing and is stored in the bottom water tank 6. In this case, the water descending across the guide plate 10 again comes into gas-liquid contact with the outside air which is directed radially inward along the guide plate 10, so that the cooling capacity of the hot water can be enhanced. Therefore, the guide plate 10 does not hinder the fall of the water cooled in the packed bed 3, and on the contrary, the presence thereof increases the gas-liquid contact area.

As described above, according to the above-described embodiment, since the dead area can be eliminated and the air distribution to the packed bed 3 can be made uniform, the cooling capacity of the large cold water tower can be sufficiently exerted. Since the gas-liquid contact after passing through the packed bed 3 can be enhanced, the cooling capacity of the entire tower can be greatly improved.
