Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling tower that increases the cooling capacity per unit installation area and reduces the installation area.

Cooling towers used to cool heat source water for air conditioning and circulating water for chemical plants are particularly large in size and are subject to constraints on installation space, so it is desirable to increase the cooling capacity per unit area as much as possible. It will be done.

However, in cooling towers that bring sprayed water into contact with outside air, there is a natural limit to the cooling capacity per unit, and it is difficult to expect a dramatic increase in capacity.

The present invention attempts to solve such problems by using a multilayered structure in which cooling towers are stacked.

However, simply stacking cooling towers will cause problems with the exhaust gas treatment on the lower floors and the outside air intake treatment on the upper floors, making it impossible to perform effective cooling operations on each floor.

Therefore, the present invention arranges at least four cooling towers 1 on lower floors in parallel, as shown in the stacked structure of FIGS. 1 and 2,
The exhaust air from the cooling tower 1 is handled by an exhaust pipe 3 (shorter than the area of the ceiling face 2) extending vertically upward from the ceiling surface 2. 4 will be installed.

In FIG. 1, four rectangular parallelepiped-shaped low-story cooling towers 1 are arranged side by side with two walls touching each other, and are placed in a space 5 surrounded by four exhaust stacks 3, which matches the shape of this space 5. It shows an exploded view of a high-story cooling tower 4 that has an external shape.
FIG. 2 schematically shows a state in which the upper floor cooling tower 4 is housed in the space 5.

The lower floor cooling tower 1 and the upper floor cooling tower 4 each have an independent and complete cooling tower structure that performs its own cooling tower function, and the internal structure thereof is a counterflow type that can be made symmetrical. Cooling towers are the most useful in practice.

When this symmetrical countercurrent type cooling tower is used in the lower floor cooling tower 1, it is not limited to the structure in which four units are arranged side by side as shown in Figs. High-rise cooling towers 4 (countercurrent cooling towers) of the same shape can be placed one after another in the dead space 5 in the upper space of these cooling towers 1 to form a cooling tower assembly with a multilayer structure.

3 and 4 are cross-sectional views showing an example of a multilayer structure using a countercurrent cooling tower, and FIG. 3 is an exploded view of the structure, and FIG.
The figures represent installation diagrams, each with an external shape corresponding to FIGS. 1 and 2.

In FIGS. 3 and 4, in the counterflow type cooling tower 1 on the lower floor, an axial flow blower 7 is driven by a motor 6 attached to each tower.
Due to the independent operation of the outside air, the outside air is forcibly drawn into the tower from the outside air intake port 8, and when the sprinkled water to be cooled falls from the sprinkler device 9 to the water tank 10, the above-mentioned outside air contacts the outside air in the packing layer 11 in a countercurrent manner. After passing through the eliminator 12, the exhaust gas is discharged from the long exhaust pipe 3 to the outside of the tower.

On the other hand, the countercurrent type cooling tower 4 on the upper floor operates independently and on exactly the same principle as the one on the lower floor.

That is, by driving the axial blower 14 driven by the motor 13, outside air is forcibly drawn into the tower from the outside air intake ports 15 installed on all sides, and when the water to be cooled falls from the sprinkler device 16 into the water tank 1γ, it is mixed with the outside air. They contact each other in a countercurrent manner in the packed bed 18, and the exhaust gas is discharged to the outside of the column after passing through an eliminator 19.

The height of the exhaust stack 3 of the countercurrent cooling tower 1 on the lower floors extends to the extent that it is approximately equal to the tower length l of the countercurrent cooling tower 4 on the upper floors. Humid air is not drawn into each outside air intake port 15 of the countercurrent cooling tower 4 on the upper floors.

Furthermore, since the exhaust stack 3 is in contact with the counterflow type cooling tower 4 on the upper floor, they support each other, resulting in an extremely stable structure.

As described above, according to the present invention, the top of the cooling tower on the lower floor is treated so that the cooling tower can be loaded.
It becomes possible to combine cooling towers in a multilayered structure in a very compact manner, and the installation area can be reduced by, for example, 20 to 25% when installing a cooling tower of a required capacity.

In addition, even in a cooling tower on a high floor, outside air intakes can be provided on all sides, allowing sufficient outside air to be drawn in for effective cooling operation, and since it is supported by exhaust stacks on all sides, it can be installed extremely stably. be.
