AI Technical Summary

Technical Problem

Existing cooling tower systems lead to water waste and water quality deterioration during evaporation and dispersion, and the equipment is unstable, making it difficult to achieve effective water quality management and water conservation.

Method used

A heat exchanger is used to recover water vapor from the exhaust gas of the cooling tower and use it as makeup water. Combined with water quality sensors and control mechanisms, the amount of makeup water and water discharge is controlled by detecting parameters such as the conductivity of the cooling water, thereby achieving water quality management and water conservation.

Benefits of technology

It achieves water-saving effects in the cooling tower system and prevents scale formation through stable water quality management, thereby reducing equipment maintenance costs and power consumption.

Abstract

A cooling tower (1) has: a tower body (2) having louvers (3) on the side, an exhaust fan (8) on the top, and a lower water tank (4) on the lower portion; a filler material (5) disposed in the tower body (2) and poured with water from above; and a controller (17) that controls a make-up water valve (15) based on a detected electric conductivity of an electric conductivity sensor (16). Condensed water generated from a heat exchanger (22) for cooling exhaust air from the exhaust fan (8) is used as make-up water.
