Mixing Device with Reversed Coiled Configuration and Use Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a tubular mixing device with a special coiled structure, where the coiling direction reverses after every one or two turns. Unlike traditional helical coils, this design maintains a straight coil axis but changes the direction of the coil at specific points, which creates strong mixing effects and improves heat transfer, all while keeping the pressure drop and manufacturing complexity low.

Use CasesContent extracted from patent full text and abstract with AI.

• Mixing of liquids or gases in industrial chemical processing applications
• Use in pharmaceutical manufacturing for better blending of active and inactive ingredients
• Wastewater treatment where thorough mixing is required before chemical treatments
• Food and beverage processing, such as in heat exchangers or flavor blending
• Microfluidic systems for lab-on-a-chip devices that require efficient, compact mixing
• Thermal homogenization in heat exchangers, especially under laminar flow conditions

BenefitsContent extracted from patent full text and abstract with AI.

• Significantly improved mixing performance, even at higher flow velocities (high Reynolds numbers)
• Superior heat transfer and thermal homogenization versus traditional coiled or straight tube mixers
• Compact and simple structure reduces manufacturing costs and complexity
• Minimal added pressure drop (only up to about 9%), making it energy efficient
• Eliminates the need for moving parts or complex internal geometries, leading to low maintenance
• Efficient mixing is less sensitive to the orientation of the fluids at the inlet, providing greater flexibility in use

Patent Abstract

The present invention relates to a tubular mixing device (6) with reversed coiled configuration (also referred to as "coiled flow reverser" CFR)) wherein after a number n of turns (2) with n=1; 2 the flow path is reverted to the opposite direction, and wherein the device (6) has an overall straight coil axis.
