Description

Waste-water heat cooling system

The present invention relates to a wastewater heat chiller for cooling high temperature wastewater, and more particularly, by forming a zigzag flow path and a spiral flow path so that the wastewater and cold water stay in the wastewater heat chiller for a long time, thereby enabling the wastewater heat to be activated. The present invention relates to a wastewater heat chiller that cools to an appropriate temperature and additionally obtains hot water.

In general, the wastewater heat cooling device is to heat the hot wastewater generated in a manufacturing plant equipped with a boiler, for example, a salt factory, a spirit factory, or a power plant, with heat exchanged with cold water to reduce the wastewater heat and additionally obtain hot water. An example of the conventional wastewater heat cooling apparatus will be briefly described with reference to FIG. 1.
