Technical details and manufacturing context for Liquid Injection Nozzles

Definition
Liquid injection nozzles are critical components of Venturi scrubbers that atomize and distribute the scrubbing liquid (typically water or chemical solution) into the high-velocity gas stream. They create a fine mist that maximizes contact surface area between the liquid droplets and pollutant particles, facilitating efficient absorption and removal of contaminants from industrial exhaust gases.
Working Principle
The nozzles operate by forcing scrubbing liquid under pressure through small orifices, creating a spray pattern that intersects with the gas stream in the Venturi throat. The high-velocity gas shears the liquid into fine droplets, creating the turbulent mixing necessary for effective gas-liquid contact and pollutant removal.
Common Materials
Stainless Steel 316L, Hastelloy C-276, Ceramic, PTFE-coated Steel
Technical Parameters
  • Nozzle orifice diameter, typically ranging from 0.5mm to 5mm depending on required flow rate and droplet size (mm) Customizable
Components / BOM
  • Nozzle Body
    Main structural housing containing internal flow channels
    Material: Stainless Steel or Corrosion-resistant Alloy
  • Orifice Plate
    Creates the spray pattern through precisely sized openings
    Material: Hardened Steel or Ceramic
  • Swirl Chamber
    Imparts rotational motion to liquid for better atomization
    Material: Stainless Steel
  • Connection Fitting
    Secures nozzle to liquid supply line
    Material: Stainless Steel
Engineering Reasoning
3.5-10.5 bar (50-152 psi) at 15-45 L/min flow rate
Cavitation occurs at vapor pressure ≤0.023 bar absolute (0.33 psi) at 25°C, erosion failure at 12.5 bar (181 psi) differential pressure
Design Rationale: Cavitation-induced pitting from Bernoulli principle pressure drop below liquid vapor pressure, combined with abrasive wear from particulate-laden scrubbing liquid at velocities exceeding 25 m/s
Risk Mitigation (FMEA)
Trigger Calcium sulfate scaling from SO2 neutralization exceeding 2.5 mm thickness
Mode: Orifice blockage reducing flow by ≥85%, causing scrubber efficiency drop below 95% particulate removal
Strategy: 316L stainless steel construction with 0.8 μm surface finish, integrated ultrasonic cleaning at 40 kHz frequency
Trigger Thermal cycling between 20°C inlet and 180°C flue gas creating ΔT=160°C
Mode: Thermal fatigue cracking initiating at stress concentration points, propagating at 0.15 mm/1000 cycles
Strategy: Inconel 625 alloy with coefficient of thermal expansion 12.8 μm/m·°C, incorporating expansion bellows with 8 mm axial movement capacity

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive erosion
Cause: High-velocity flow of abrasive particles in the liquid stream gradually wears away the nozzle orifice and internal surfaces, leading to increased spray angle and reduced pressure.
Cavitation
Cause: Sudden pressure drop below the vapor pressure of the liquid at the nozzle orifice causes vapor bubble formation and collapse, creating micro-jet impacts that erode the nozzle material.
Maintenance Indicators
  • Irregular spray pattern or visible dripping from nozzle tip during operation
  • Audible hissing or sputtering sounds indicating inconsistent flow or partial blockage
Engineering Tips
  • Implement regular ultrasonic cleaning cycles to remove internal deposits without disassembly, maintaining optimal flow characteristics
  • Install dual-stage filtration upstream with progressively finer mesh sizes (e.g., 100μm then 25μm) to capture abrasive particles before they reach the nozzle
