Description

technical field [0001] The invention relates to the engineering fields of petrochemical industry, biological reaction, environmental protection, etc., and is a liquid-liquid helical tube swirl reactor integrated with mixing, reaction and separation for liquid-liquid heterogeneous reaction. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The immiscible liquid-liquid heterogeneous reaction process widely exists in petrochemical, biological reaction, environmental protection and other engineering fields. The key to liquid-liquid heterogeneous reaction is to realize the efficient mixing and full contact of the liquid-liquid two phases. In order to increase the reaction rate, the contact and mixing between the phases is dispersed in the continuous phase in the form of droplets through the dispersed phase, and the dispersion process of the dispersed phas...

AI Technical Summary

Problems solved by technology

The microreactor can reduce the dispersed phase droplets to the nanometer level, but the output is small; the mixing conditions at different positions in the stirred tank reactor are different, the degree of turbulence near the stirring paddle or impeller is relatively high, and the flow out of the wall is relatively smooth, which is easy It causes uneven mixing of the reaction materials. For some fast reactions with a short reaction time, a large amount of heat will be released during the reaction. A coil must be installed in the stirring tank to release the heat generated by the reaction; the static mixer can be used in a wide Reynolds It can be used within a certain range and has no moving parts, but due to its complex internal structure, cleaning and maintenance inside the reactor is a big problem

Moreover, the above-mentioned reactors are purely used as mixing reaction equipment, and a separation module must be added in the subsequent process to complete the entire process flow. Therefore, in addition to improving the mixing level for heterogeneous reactions with short reaction times, how to achieve timely separation of products to avoid The occurrence of side reactions is also a key issue in improving product yields
