INDUSTRY COMPONENT

Feed Inlet Nozzles

Feed inlet nozzles are precision-engineered components that control the introduction of reactants into neutralization reactors for safe and efficient chemical processing.

Component Specifications

Definition
Feed inlet nozzles are specialized fittings installed on neutralization reactors designed to precisely meter and direct the flow of acidic or basic reactants into the reaction vessel. These components ensure proper mixing, prevent backflow, and maintain process safety by controlling entry velocity and dispersion patterns. They are engineered to handle corrosive chemicals, high temperatures, and varying pressures while maintaining structural integrity and leak-proof operation throughout the neutralization process.
Working Principle
Feed inlet nozzles operate by creating a controlled entry point for reactants into the reactor vessel. They utilize engineered geometries (such as tapered orifices, diffusers, or spray patterns) to regulate flow velocity, promote turbulent mixing with existing contents, and prevent splashing or localized concentration buildup. The nozzle design ensures reactants enter at optimal positions relative to agitators or mixing elements, facilitating rapid and complete neutralization reactions while minimizing thermal or chemical gradients.
Materials
Stainless steel (316L, 304), Hastelloy C-276, titanium, PTFE-lined carbon steel, or ceramic composites depending on chemical compatibility requirements. Materials must resist corrosion from acids (e.g., sulfuric, hydrochloric) and bases (e.g., sodium hydroxide) at operating temperatures up to 200°C and pressures up to 10 bar.
Technical Parameters
  • Flow Capacity 0.5-50 m³/h
  • Surface Finish Ra ≤ 0.8 μm for sanitary applications
  • Connection Type Flanged (ANSI/ASME B16.5), threaded (NPT), or welded
  • Pressure Rating Up to 10 bar
  • Orifice Diameter 10-100 mm
  • Temperature Range -20°C to 200°C
Standards
ISO 2852, DIN 11851, ASME B31.3
