1. Product Introduction
1.1 Product Description
The Ion Exchange Teaching Experiment Device is a teaching device used to demonstrate the principles of ion exchange in water treatment. This device visually demonstrates the softening (removal of calcium and magnesium ions), dealkalization (removal of bicarbonate ions), and complete desalination (deep removal of cations and anions) processes of water using cation exchangers, anion exchangers, and their combinations. Simultaneously, the device supports chemical regeneration of depleted ion exchangers, fully presenting the working cycle of ion exchange technology. The device integrates functions such as flow regulation and real-time conductivity monitoring, making it suitable for principle teaching and experimental operation in higher education institutions and vocational training in fields such as chemical engineering and environmental engineering.
1.2 Product Features
Modular Process: Cation and anion exchange processes can be run independently or in series, flexibly demonstrating different water treatment objectives.
Visual Design: Transparent exchange column design allows direct observation of the ion exchanger state and liquid flow.
Real-time Monitoring: Integrated flow meter and handheld portable conductivity meter, enabling continuous monitoring and recording of changes in flow rate and water conductivity.
Integrated Supply: Equipped with a four-chamber liquid storage tank, it can simultaneously hold raw water, rinsing water, dilute hydrochloric acid, and sodium hydroxide, eliminating the need for an external water source; the experiment is self-contained.
Safe Teaching: The design fully considers teaching safety, clearly marking operational risk points and providing necessary personal protective equipment.
Complete Experiment Cycle: Includes not only ion exchange experiments but also exchange resin regeneration experiments, forming a complete learning loop
