Field of the Invention The present invention relates to a method of bringing water into contact with air and cooling the water by the heat of vaporization of the water, using the cooled water directly, or using a pipeline system other than this.

The cooling tower 1 has a base 3, on which a packing material 5, which will be described in more detail later, is supported. A louver 7 is provided on the outer side of the filling material 5 so that air is taken in from the outside through the louver and passes through the filling material into the space inside the filling material sandwiched between the filling materials. This space extends longitudinally and is provided at one of the spaces with an air drive which causes an upward flow of air. In this example, the air drive is a blower 11 of the type having rotating vanes. As can be understood from the above description, air passages are formed on the base 3 through the louvers 7, the fillers 5, the spaces between the fillers, and the spaces extending upward from there.

Hot water with a raised temperature is supplied. The warm water is poured into the filling material 5 through the fin tube 17 described later. Fillers are well known in the art, for example, in the form of a mesh-like material that forms a film of water over a wide area to provide a large contact area between the water and the air passing through it. Due to the action of the blower 11, the outside air A 1 is louvered.
The air enters the filling material 5 through, and cools the hot water by coming into contact therewith, and at the same time, the temperature rises and becomes the saturated air containing the steam to become the saturated air B.

Is provided. This is in mechanical contact with a large water drop to prevent it from proceeding further. The water, which has been deprived of the heat of evaporation by contact with air and cooled, falls from the filler 5 and the eliminator 19 to the bottom of the base 3
The water is collected in a water tank (not shown) provided in the tank, and then supplied again to a required place through a cooling water passage (not shown).

求される。The air B containing water vapor is driven upward by the blower 11 and discharged from the outlet 21. At this time, since it is cooled by the outside air, minute drops of water are generated from the air B and become white smoke. This tendency becomes more remarkable as the temperature of the outside air becomes lower, and it becomes a particularly remarkable phenomenon in winter. Since this white smoke is a water droplet formed by condensing evaporated water, it is not harmful in itself, but it is likely that it causes a bad view, is misunderstood as a fire at night, and is a source of pollution. Since it is received, it is required to prevent its occurrence as much as possible.

ることが意図されている。Therefore, conventionally, means for preventing white smoke has been taken, and in the example of FIG. 5, the method of mixing the air B with the heated outside air is adopted. That is, as described above, the hot water supply pipe 15 communicates with the fin tube 17. A damper 22 is provided outside the fin tube,
Open air A through the combination of damper and fin tube
1 can be taken into the air passage 13. The outside air cools the hot water as it passes through the fin tubes 17, and itself is heated to become air A 2 having a low water vapor saturation and enters the passage 13 and is mixed with the air B. As a result, mixed air C
Is intended to keep its water vapor content below the saturation curve so that white smoke does not occur when cooled by the outside air.

Further, increasing the size of the heat exchanger such as the fin tube in order to obtain a better result causes a large increase in cost.

A water drain ring 69 is provided. This guides the water from the inner wall of the water collecting electrode to the outer wall by going around the upper end, and is fixed to the upper end of the water collecting electrode at an appropriate position in the circumferential direction. Provides a space that extends around the upper end of the collector electrode as shown and guides water to the outer wall of the collector electrode.

大部分が回収され補充水の大巾な節約となる。A potential of (-) is applied to the discharge electrode, and a potential of (+) is applied to the water collecting electrode, and the potential difference is a value sufficient to cause corona discharge. When the air-fuel mixture D containing water drops is driven upward by the action of the blower 11 and enters the cylindrical water collecting electrode, the water drops therein are instantly charged by the action of corona discharge and are almost completely collected. Adsorbed on the inner wall of a cylinder. The adsorbed water flows down along the inner wall, passes through the space outside the guide portion 73, and is stored in the tray 71. This water is taken out through the plug 75, returned to the water tank (not shown) existing in the base 3, and joins the cooled water flowing down from the filler. This prevents the consumption of cooling water. In the filler, a large amount of water evaporates due to contact with air, which is about 1% at a cooling temperature difference of 6 ° C.
However, if this water is discharged from the cooling tower as it is, the amount of water required for replenishment becomes large, and there are problems of water resources and cost. In the present invention, most of the evaporated water is recovered, which greatly saves the replenishment water.

Water flows to the outer wall of the water collecting electrode through the space between the upper end of the water collecting electrode and the water cutting ring, and is received by the support member 65a. The water thus collected flows through the drainage ports 77, 79 provided in the support members 65a, 65b to the tray.

It is also possible to use a combination of the above-mentioned poles, a combination of a plate-shaped pole and a linear pole, a combination of a plate-shaped pole and a plate-shaped pole, and the like. However, in the embodiment shown in the drawing, the water collecting electrode having a large area exists at the same distance from the linear discharge electrode, and a large water drop charging effect can be obtained with a compact configuration.

Further, water drops can be removed more effectively by providing an arbitrary means so that the air-fuel mixture does not flow upward through a portion other than the inside of the cylindrical water collecting electrode.
