Reactor vessel
Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries to perform processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation. Examples include reaction vessels, reaction kettles, decomposition kettles, and polymerization reactors. Common materials include carbon-manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials.

Classification of Reactors
Reactors can be categorized by structure into three types:
Each design has specific applications, advantages, and limitations. Additionally, reactors are classified by material and purpose:
- Components**: Vessel body, lid, jacket, stirrer, transmission system, shaft seal, and support.
- Materials: Carbon-manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel), or composites.
- Structural Types: Open flat head, open butt-welded flange, or closed.
- Stirring Mechanisms: Anchor, paddle, turbine, propeller, or frame-style blades. Multi-layer impellers are used for reactors with high height-to-diameter ratios.
- Sealing Types: Packing seal, mechanical seal, or magnetic seal.
- Heating/Cooling Methods:
- Heating: Electric, hot water, thermal oil circulation, or external/internal coil heating.
- Cooling: Jacket cooling or internal coil cooling.
- Structure: A steel container lined with high-silica glass fused to its inner surface at high temperatures.
- Advantages: Combines the chemical stability of glass with the mechanical strength of steel, making it ideal for highly corrosive environments.
- Design: Utilizes a magnetic coupling system to connect the stirrer and motor, replacing dynamic seals with static seals.
- Advantages: Leak-proof, suitable for handling flammable, explosive, toxic, or highly permeable substances.
- Applications: Essential for processes like sulfonation, fluorination, hydrogenation, and oxidation in petroleum, chemical synthesis, polymer production, and food industries.
