The spray water, which indirectly cools the treated water flowing through the inside and sprays the heated water itself, comes into the cooling tower A0 from the outside air intake A3 and comes into contact with the rising outside airflow in countercurrent, causing the latent heat of vaporization. After being cooled by the action, the treated water is sequentially contacted with the heat exchange coil to cool the treated water. The spray water that undergoes heat exchange between the outside air stream and the treated water as described above is finally dropped and collected in the lower water tank A4, is again pumped by the pump P, and is sprayed by the spray device A2.
It is returned to 0 and sprayed on the heat exchange coil 10.
