Industrial Circulating Cooling Water Online Monitoring System —— pH, Conductivity, ORP Intelligent Control Solution

Introduction

Industrial circulating cooling water system is one of the auxiliary systems with the highest energy consumption and maintenance costs in factory production. Unstable water quality can easily cause scaling, corrosion, and microbial slime problems in pipelines and heat exchangers, leading to a 20%-40% decrease in heat exchange efficiency, significantly shortened equipment life, and high annual costs for acid washing, downtime maintenance, and chemical agents.

Industry Pain Points

Traditional manual periodic dosing and sampling detection methods have strong hysteresis and cannot grasp real-time water quality dynamic changes. pH fluctuations, excessive conductivity, and abnormal ORP oxidation-reduction potential often lead to severe corrosion or scaling, especially prominent during summer high temperatures or working condition changes. Enterprises face multiple problems such as frequent equipment failures, increased energy consumption, safety hazards, and environmental protection pressure.

Why Online Monitoring is Needed?

Real-time continuous monitoring and automatic control systems can dynamically adjust dosing amounts according to water quality parameters, achieve precise dosing, maintain water quality in the optimal range, and significantly improve system operation efficiency.

Industrial Circulating Cooling Water Online Monitoring System Architecture

The system adopts a layered IoT architecture:

Sensor layer (installed in cooling water bypass pipeline) → Data acquisition and control layer (RTU local processing and linkage) → Transmission layer (4G/LoRa) → Cloud platform layer (data analysis, visualization, remote control) → Application layer (enterprise monitoring center and mobile terminal).

Working Principle: Sensors collect key parameters of circulating water in real time, process them through the collector, upload to the cloud platform and compare with set thresholds. The system automatically controls the dosing device addition amount according to pH, ORP, and conductivity to maintain water quality stability, forming an intelligent closed loop of “monitoring—analysis—control—optimization”.
