AI Technical Summary
The existing bypass filter discharges water directly into the cooling tower, causing the water temperature to rise. In addition, during sandstorms, sediment enters the circulating water pipeline, affecting water quality.
A spray pipe and water-blocking and sand-removing equipment, including a water curtain and a sand removal box, are installed downstream of the side filter. The spray pipe sprays the water from the side filter onto the air inlet of the cooling tower. The water curtain prevents mud and sand from entering, and the sand removal box separates particles. The separation efficiency is improved by using buffer floats and a self-lubricating layer.
It effectively prevents sediment from entering the cooling tower, reduces the outlet water temperature, ensures the quality of circulating water, and improves the reliability and practicality of the circulating water system.
