Description
Why Plastic Static Mixer
For corrosive liquids like acids alkalis and aggressive chemicals stainless steel mixers are expensive and still susceptible to corrosion over time. DAGYEE Plastic Static Mixer made from PVC or PP offers excellent chemical resistance at a fraction of the cost. Lightweight easy to install and maintenance free.
Model
Applicability
Re SD
Often suitable for mixing, reaction and extraction of low and medium viscosity fluids. Solid-liquid mixing and gas-liquid mixing are also applicable. Medium viscosity ≤ 10⁵ cP, can be accompanied by less impurities.
Re SK
Often suitable for various viscosity liquids or liquid-solid and liquid-gas mixing, reaction, extraction, absorption, injection molding, heat transfer and more. Viscous media with small flow rate and impurities are especially suitable. Medium viscosity ≤ 10⁶ cP.
Re SL
Often suitable for heat exchangers with viscosity ≤ 10⁶ cP or for polymer media mixing, heat transfer, mixing and thermal reaction simultaneously.
Re SY
Often suitable for mixing, reaction, heat transfer and other processes of medium and low viscosity. Medium viscosity ≤ 10⁶ cP.
How does a Static Mixer work?
A static mixer works by using fixed internal elements to continuously blend two or more fluid streams as they flow through the mixer. Unlike dynamic mixers which use moving parts or motors a static mixer has no moving components. The fluid passes through specially designed helical or corrugated elements which divide recombine and rotate the flow creating radial mixing and uniform dispersion. The result is consistent homogeneous output regardless of flow rate variations. The DAGYEE SK Series uses a single helical twist element that operates efficiently at low pressure drop and low shear making it ideal for high viscosity and shear sensitive fluids.
Flow Regimes:
-
Laminar Flow Mixing (Low Reynolds Number): Achieved through flow division and radial redistribution.
-
Turbulent Flow Mixing (High Reynolds Number): Enhanced by eddy formation and chaotic advection.
-
The degree of mixing depends on the number of elements and the mixer’s geometric design.
