Micro-nano scale multiphase flow process enhanced reaction device

Abstract

A micro-nano scale multiphase flow process enhanced reaction device includes a compressor, a feed pump, a micro-nano multi-phase flow generation device, and a multi-phase flow process enhanced reactor. According to fluid flux or hydraulic loading in the micro-nano multi-phase flow generation device, the multi-phase flow process enhanced reactor can be composed of two or more micro-nano multi-phaseflow micro-element generators connected in parallel. A dispersion medium generator and a base are disposed inside the multi-phase flow process enhanced reactor. Compared with conventional bubbling towers, packed beds and stirred tank type gas-liquid reactors, multi-phase fluid produced by the device can make the gas-liquid two specific surface area increase by 1-2 orders of magnitude to 10<4>-10<5> m<2> / m<3>, a liquid side total volume mass transfer coefficient kL[alpha] value in a gas-liquid two-phase reaction controlled by a liquid film can be significantly increased to a range of 0.5-10 s<-1>, and the device has obvious competitive advantages in terms of phase microscopic transmission efficiency, molecular diffusion transfer rate, gas-liquid phase ratio interfacial area, specific energy input density, comprehensive energy efficiency, device operation stability, safety guarantee, and the like.

Problems solved by technology

[0004] Although some of the equipment and processes in the above-mentioned chemical process intensification technologies have been applied in actual industrial production and have achieved certain application effects, there are still problems in varying degrees such as insignificant improvement in process efficiency, complex equipment structures, high equipment investment, and technical problems. Low economic competitiveness, limited energy consumption reduction, narrow application technology field, obvious amplification effect, and relatively large transformation of existing chemical process, so it is urgent to develop a new type of high-efficiency chemical process intensification equipment and technology The method integration system can fundamentally solve the problems existing in the existing chemical process intensification technology equipment and processes, and from the structure optimization design of the process intensification reactor and the mixing at the microscopic level, the transfer process intensification and the reaction kinetics and thermodynamics. Starting from the structure-activity relationship, a new type of chemical transfer process intensification and intensification process technology system has been developed, which provides a basic guarantee for large-scale industrial applications
