Einsatz und Auslegung statischer Mischer

Abstract

Abstract Application and design of static mixers . Static mixers are units without, or only with fixed, internal fittings which effect the mixing of flowing materials with the aid of their kinetic energy. They are used for continuous homogenization and dispersion, for limitation of the residence time spectrum, and for raising heat and mass transfer in all areas of chemical engineering. Over 20 static mixers are presented, and compared with regard to pressure drop, mixing quality, energy consumption, and residence time and heat transfer behaviour. Important selection criteria are reported. Static mixers have the following advantages over dynamic mixers: use for a wide range of viscosities, narrow residence time spectrum, readily adaptable to existing pipe systems, frequently require no extra space (in‐line mixers), negligible maintainance and wear, low investment and operating costs.
