AI Technical Summary

Technical Problem

When traditional cooling systems change factors such as process material flow, temperature and dirt thickness, it is difficult to accurately control the cooling water temperature, affecting the cooling effect and energy utilization efficiency.

Method used

The circulating cooling water control system and method based on dirt thickness detection is adopted. By monitoring the inlet/output temperature, heat exchanger inlet/output water temperature, cooling water flow and other data, combined with dirt thickness detection, the target flow rate and temperature difference of cooling water are calculated, and the speed and flow rate of the fan and circulation pump are adjusted through the intelligent control unit.

Benefits of technology

Accurate control of the temperature of circulating cooling water is achieved, ensuring that the materials are cooled to a suitable temperature, improving energy utilization efficiency, reducing operating costs, meeting the strict temperature requirements of the production process, and improving product quality and production stability.
