Glass-lined Reactor
Reaction Equipment
Glass-Lined Reactor
1. Product Overview
The glass-lined reactor is made by applying a high-silicon glass enamel to the inner surface of a steel vessel and firing it at high temperature, producing composite equipment that combines the mechanical strength of steel with the corrosion resistance of glass. Each unit consists of the glass-lined body, agitator, drive, seal, jacket and control system.
Typical applications: chemical synthesis, pesticide production, dye intermediates, pharmaceutical APIs, food processing and other corrosive duties.
Key features: resistance to most inorganic and organic acids and organic solvents, a smooth non-stick surface, good thermal-shock resistance, and a lower cost than special-alloy reactors.
2. Working Principle
Once the materials are charged into the glass-lined body, the agitator rotates to blend them evenly. Steam or thermal oil circulates through the jacket for heating, or cooling water for cooling. The glass lining keeps corrosive media away from the steel substrate so the vessel itself is not attacked, while the control system automatically regulates the jacket medium flow from temperature-sensor feedback to hold a stable process temperature.
3. Classification
By Structural Form
| Type | Features | Typical Applications |
|---|---|---|

| Closed type | Cover and body connected by flange | Medium-low pressure reaction, high sealing requirements |
| K-type (with manhole) | Manhole on cover, easy maintenance | Large reactors, requires internal entry |
By Agitator Type
| Type | Features | Typical Applications |
|---|---|---|
| Anchor stirrer | Wipes the wall to prevent build-up on the glass lining | High viscosity materials |
| Frame stirrer | Combines axial and radial flow | Medium viscosity materials |
| Paddle stirrer | Simple structure | Low viscosity general mixing |
