Injection Nozzle/Diffuser: Flow Rate Range 0.5-20 L/min CO₂

Component Specifications

Definition

The Injection Nozzle/Diffuser is a critical component in CO₂ Injection Systems designed to precisely meter and disperse carbon dioxide into liquids. It consists of a nozzle section for controlled injection and a diffuser section for uniform bubble distribution, ensuring consistent carbonation levels. Engineered for high-pressure operation, it maintains precise flow rates and prevents gas channeling or uneven dispersion.

Working Principle

Operates by receiving pressurized CO₂ from the supply line, accelerating it through a constricted nozzle orifice to create a high-velocity jet, then expanding through a diffuser section that breaks the gas stream into fine, uniform bubbles. The pressure differential between the nozzle inlet and the liquid medium drives injection, while the diffuser geometry controls bubble size and distribution pattern.

Materials

Stainless Steel 316L (primary), PTFE seals, Hastelloy C-276 for corrosive applications, Ceramic (Al₂O₃) for abrasive resistance. Surface finish: Ra ≤ 0.8 μm for fluid contact surfaces.

Frequently Asked Questions

What maintenance is required for injection nozzles?

Regular cleaning with food-grade sanitizers, inspection for orifice wear or clogging, and seal replacement every 6-12 months depending on usage.

How does nozzle orifice size affect carbonation?

Smaller orifices create finer bubbles and better dissolution but require higher pressure; larger orifices allow higher flow rates but may produce less uniform carbonation.
