A Static Mixer, such as the Coated Stainless Steel Mixing Element, is an efficient mixing device without moving parts. These mixers are widely used in the petroleum refining and chemical industries, as well as in sectors like medicine, food, mining, plastic extrusion, and environmental protection. The X Grid Static Mixer, for instance, is designed for high efficiency in various mixing applications. Compared with traditional mixing equipment such as mixers, colloid mills, homogenizers, and Venturi tubes, static mixers have the advantages of a simple process, compact structure, low energy consumption, low investment, high operational flexibility, no need for maintenance, and good mixing performance.
The static Mixer For Viscous Liquids is specifically designed to handle high viscosity fluids, ensuring thorough mixing even in challenging conditions. Stainless steel staic mixing elements are used in these mixers to provide durability and resistance to corrosion, which is crucial in many industrial processes.
Operational Principle: The mixing process of a static mixer is carried out by a series of mixing units of different specifications installed in a hollow pipeline. Due to the action of the mixing unit, the fluid sometimes rotates left and sometimes turns right, constantly changing the flow direction. This not only pushes the central fluid towards the periphery but also pushes the peripheral fluid towards the center, resulting in a good radial mixing effect. At the same time, the rotational action of the fluid itself also occurs at the interface of adjacent components, and this perfect radial circulation mixing effect achieves the goal of uniform mixing of materials. Any process involving the mixing, emulsification, neutralization, absorption, extraction, reaction, and enhanced heat transfer of liquid-liquid, liquid-gas, liquid-solid, and gas can benefit from the use of static mixers, replacing traditional related equipment with these more efficient and reliable alternatives.
Product advantages
Continuous process, the mixing process is not interrupted;
Minimal shear force does not damage the mixture, such as flocs;
The mixing effect is computationally controllable (CoV deviation), with a maximum CoV range of 5% according to customer requirements. The fluid concentration across the entire cross-section is continuous and balanced, so the measured values have high representativeness and can effectively control the device;
The mixing distance and installation space are very small, and the static mixer itself is a part of the pipeline, which can be regarded as a special pipeline, avoiding the shortcomings of traditional mixing tanks and so on;
High mass transfer efficiency, very low pressure drop and energy consumption;
No moving parts, no wear, and almost no maintenance costs;
It will not be blocked, and the installation method and material can be of any shape, size, and material;
Compulsory mixing of the entire process logistics can greatly reduce the volume of storage tanks, and static mixers can even eliminate the use of storage tanks.
Product pressure drop
The pressure drop calculation of the product is based on the hydraulic diameter and takes into account the influence of porosity and friction coefficient.
The static mixer is used in pipelines and does not produce a significant pressure drop. When the system pressure using a static mixer is relatively high, the pressure drop generated by the static mixer can be ignored. If the system pressure using a static mixer is relatively low, it is necessary to verify the pressure drop of the static mixer. The pressure drop calculation method for static mixers varies depending on the model of the mixer.
Static mixer installation model and installation form SV gas-liquid phase: vertical installation (parallel and reverse flow), liquid-gas phase: horizontal or vertical (bottom-up) installation, with similar device effects
Gas gas phase: horizontal or vertical (with small density difference in gas phase and unlimited direction) installation SX liquid liquid phase: horizontal or vertical (from bottom to top) installation, similar device effect SL liquid liquid phase: horizontal or vertical (from bottom to top) installation, similar device effect
Liquid solid phase: horizontal or vertical (bottom-up) installation of SH gas liquid phase: the flange size at both ends is determined by enlarging the nominal diameter of the product by one grid. Products using SL type installation form of SK active unit usually have one end without a positioning device as the inlet end.
