Corrosion Inhibitor (scale Inhibitor) Dosing Device

Process Principle

The working principle of corrosion inhibitor (scale inhibitor) dosing device: During natural operation, industrial circulating cooling systems are prone to scaling or corrosion due to the combined effects of factors such as hardness, alkalinity, pH value, concentration ratio, temperature, and ambient humidity. Both negatively impact the safety and operational efficiency of the circulating cooling system. To inhibit scaling or corrosion, corrosion inhibitors or scale inhibitors need to be artificially added to the water. Commonly used corrosion inhibitors and scale inhibitors include polyphosphates, zinc salts, polycarboxylate salts, and phosphonates , etc.

Process Overview

This device mainly consists of four parts: a drug solution preparation system, a metering and dosing system, a safety system, and a control system.

. Dosing control can be manual or automatic, based on control signals output from a higher-level system.

Application areas

Cooling circulating water treatment for thermal power generation or petrochemical plants
