- Materials of Construction: Stainless steel (304/316L standard), Hastelloy, Inconel, or carbon steel with corrosion-resistant linings (e.g., glass-lined for chemical resistance).
- Agitator Types: Propeller, turbine (radial/axial flow), pitched blade, anchor, helix, or electromagnetic induction for non-contact stirring.
- Heat Transfer Area: Jacketed (conventional, half-pipe, or dimpled) with areas up to 20 m²/m³ vessel volume; internal coils optional.
- Sealing System: Mechanical seals, magnetic couplings (for zero leakage in hazardous applications), or lip seals.
- Weight: 500 kg to 20,000 kg (varies by capacity and configuration).
These parameters ensure compliance with process requirements, such as Reynolds number for mixing efficiency and power consumption calculations.
Design and Construction Standards
AIXBOILER agitated pressure vessels are engineered in full compliance with national and international codes. Our manufacturing process includes advanced welding, non-destructive testing (NDT), and hydrostatic testing.
- Primary Standards: GB150/151 (Chinese Pressure Vessel Code), with options for ASME Section VIII Div. 1/2, PED (EU), and other certifications.
- Wall Thickness Calculation: Based on design pressure, temperature, material allowable stress, joint efficiency (typically 1.0 for full radiography), and corrosion allowance (3-6 mm standard).
- Nozzle and Connections: Custom flanges, sight glasses, and ports for inlets/outlets, sensors, and safety valves.
- Baffles and Internals: Integrated baffles to prevent vortex formation and enhance mixing patterns.
- Surface Finish: Internal polishing up to 0.4 Ra (electropolish) for sanitary applications; external finishes for corrosion protection.
Finite element analysis (FEA) is used for complex loads, including agitator-induced vibrations and external nozzle stresses per WRC bulletins.
Agitator System Details
The heart of our mixing equipment is the agitation system, designed for optimal flow patterns and energy efficiency.
- Impeller Selection: Axial-flow for suspension, radial-flow for dispersion; multi-layer options for complex fluids.
- Drive Mechanism: Top-mounted electric motor with gearbox; explosion-proof (ATEX) options available.
- Electromagnetic Agitation: Innovative non-contact stirring using induction principles, ideal for sterile or sealed processes (no shaft penetration, zero contamination risk).
- Power Requirements: Specific power input (P/V) from 0.5 to 5 kW/m³, optimized for just-off-bottom suspension (Njs).
- Monitoring: Integrated sensors for speed, torque, temperature, and pressure.
This system supports batch, semi-batch, or continuous operations, with minimal maintenance due to robust bearings and seals.
Applications
AIXBOILER agitated pressure vessels excel in:
- Chemical reactions (polymerization, hydrogenation).
- Pharmaceutical blending and fermentation.
- Food and beverage homogenization.
- Biomass processing and extraction.
