Static Mixer |
| The static mixer is designed to stir and mix fluids (gas/liquid). The fluids and injected into the static mixer under pressure, the elements are rectangular square plated twisted at 180°. According to the direction of the twist, One can distinguish a right element and a left element. Flow regimes of division, rotation and flow reversal are mixing principles of the static mixer producing the number of striations as flow travels through the mixing chamber. The static mixer is economical from the point of view of maintenance costs, energy consumption and installation space. |

Typical Application
• Blending and mixing of fluids (gas/liquid)
• Mixing of high viscosity (500,000 cp.)
• Dispersing immiscible liquids
• Dilution of fluids
• Homogenization of liquids.
• Contracting of gas/liquid
• Heating and cooling of fluids
• Adjustment and control of pH
• Neutralization of liquids

The Minimum Number of Elements
• Reynolds number should be determined to specify the required number of elements. The Reynolds number can be calculated namely;
Where
Q = fluid flow rate, m3 /sec
ρ = fluid density, kg/ m3
µ = viscosity, kg/m-sec
d = inside diameter of pipe, m.
The number of elements recommended are as follows:
