Water is supplied to a wet part 5 in which a large number of fillers 4 such as baffles are arranged and formed into a film-shaped water film or fine water drops by a corrugated plate or a baffle plate. Two
Is cooled by the fan 6 located above the cold water tower body 3.
Is cooled by being in direct contact with the outside air 8 sucked from the outside air intake section 7 (at this time, a part of the water 2 is evaporated and the latent heat of evaporation is removed from the water 2), and flows down or falls from the wet section 5. Then, the water is temporarily stored in the water receiving portion 9 below the cold water tower body 3, sucked by the pump 10 from the water receiving portion 9 and circulated to the heat source 1.

1 is discharged from an air discharge port 12 provided in the fan 6 installation portion above the cold water tower body 3. At this time, the air outlet 1
The air 11 discharged from 2 has a very high humidity because it contains a large amount of water vapor due to being in direct contact with the water 2 in the wet portion 5, and therefore the temperature of the outside air 8 such as in winter is high. When the temperature is low, the air 11 discharged from the air discharge port 12 is exposed to the cold outside air 8 and becomes low temperature, and the water vapor contained in the air 11 is condensed to form white smoke, which may cause white smoke pollution. There is. Therefore, a heat exchanger 13 that can warm the outside air 8 without contacting the water 2 by passing the water 2 through the finned tube is provided on the upper side of the packing 4 to connect the wet portion 5 and the air outlet 12. A dry type portion 14 is formed therebetween, and the water 2 discharged from the heat source 1 is first passed through the heat exchanger 13 above the packing 4 to generate dry air 15 having a relatively high temperature and low humidity, and the wet type portion 5 is used. The dry air 15 is mixed with the high-humidity air 11 that has passed through immediately before being discharged from the air discharge port 12, and the relative humidity of the air 16 discharged from the air discharge port 12 is reduced, whereby the outside air 8 Even if the temperature is low, the pollution of white smoke can be prevented.

However, the heat exchanger 13 of the dry type portion 14 is Since the water 2 which is not so high in temperature of 30 to 50 degrees and which is heated by cooling the heat source 1 is used,
A large heat exchanger 13 was required to secure the dry air 15 necessary to prevent white smoke pollution.

Since the process of cooling by using and the process of preventing the generation of white smoke by the dry air 15 are the same as those in FIG. 10, their description will be omitted.

へ直接導入するようにしている。In the present invention, the surplus steam 19 generated in a factory or plant is supplied to the heat exchanger 18 through the steam supply passage 20 to dry air 15 for preventing white smoke.
And the water 2 warmed by cooling the heat source 1 is placed below the heat exchanger 18 of the dry section 14
I am trying to introduce it directly to.

３よりも数メートルも小さくすることができる。As described above, when the excess steam 19 generated in a factory or plant is used, the steam 19 usually has a relatively high calorific value at a temperature of about 150 to 200 ° C., and therefore FIG. As compared with the case of using the water 2 warmed by cooling the heat source 1 as described above, it is possible to obtain the dry air 15 having a higher temperature, and therefore, to secure the dry air 15 necessary for preventing white smoke. The heat transfer area of the heat exchanger 18 can be reduced to reduce the amount of dry air 15 generated, and as a result, the heat exchanger 18 can be made much smaller than the heat exchanger 13 of FIG. For example, in the case of large-scale cold water or the like, the height dimension of the heat exchanger 18 is set to the heat exchanger 1 of FIG.
It can be smaller than 3 by several meters.
