Functional principle of static mixers
static mixers are used in continuous processes where they homogenize fluids with no moving parts. Pumps or blowers are used to deliver the components to be mixed at the desired volumetric flow rates and to also supply the pressure energy required for mixing. Typical sizes of static mixers range from very small laboratory size units from DN8 (1/4'') up to DN300 (12'') or even larger on request.
a static mixer consists of individual mixing elements stacked in series. Each mixing element is oriented 90° relative to the adjacent mixing element to create homogeneous mixing in both the horizontal and vertical directions. The static mixing elements divide and recombine the feed materials so that the stream exiting the static mixer is homogeneous with regard to concentration, temperature and velocity which are equalized throughout the entire pipe cross-section.
The number of mixing elements required for a specific application is a function of the customer’s process and system requirements with consideration for the degree of mixing required, pressure ｄｒｏｐ limitations and fluid properties such as flow rate, viscosity, density, etc.
As with most process equipment, there are sometimes dramatic differences in performance between various designs. This statement also holds true for static mixers. For example, Figure #3 shows the homogeneity achieved with the HT helical static mixer which when compared to the performance of the GX static mixer , a dramatic difference in mixing quality is seen. Although the HT static mixer performance is dramatically lower than the GX static mixer , the HT static mixer is still used extensively because of its lower pressure ｄｒｏｐ and open non-fouling design.
