Stainless Steel Reactor
1. Product Overview
The stainless steel reactor is the core vessel for physical and chemical processes in the chemical, pharmaceutical and food industries. It combines a vessel body with an agitation system, drive unit, sealing system, heating/cooling jacket and electrical control system. Heating or cooling is supplied through external media and combined with agitation to deliver homogeneous mixing and a controlled reaction process.
Typical applications include fine chemical synthesis, pharmaceutical intermediate production, food additive preparation, resin polymerization and new energy material synthesis.
Key characteristics: strong corrosion resistance, high heat-transfer efficiency, reliable sealing, a wide choice of impeller types, and suitability for high-temperature and high-pressure duty.
2. Working Principle
Once the materials are charged into the vessel, the agitator driven by the motor creates both macro-mixing and micro-dispersion. Heating or cooling media — steam, thermal oil or cooling water — circulate through the jacket or internal coil to hold the process temperature. Gases generated during the reaction can be vented through the top nozzle or routed to a condensate-reflux system. Based on feedback from temperature and pressure sensors, the intelligent control system automatically adjusts the heating/cooling valve opening and agitator speed to keep process parameters constant.
3. System Classification
By Structural Form
| Type | Features | Application Scenarios |
|---|---|---|
| Open flat cover | Cover and body connected by flange, can be opened | Atmospheric or low-pressure reaction, manual material feeding |
| Closed welded | Body and cover integrally welded | Medium-high pressure reaction, high sealing requirements |
| Closed flanged | Cover and body connected by flange, detachable | Medium-low pressure reaction, requires regular cleaning |
By Agitator Type
| Type | Features | Application Scenarios |
|---|---|---|
