摘要

Abstract

It is generally recognized that internal-loop reactors are well-developed mass and heat-transfer multiphase flow reactors. However

the internal flow field in the internal-loop reactor is influenced by the structure parameter of the reactor

which has a great effect on the reaction efficiency. In this study

the computational fluid dynamics simulation method was used to determine the influence of reactor structure on flow field

and a volume-offluid model was employed to simulate the gas-liquid

two-phase flow of the internal-loop micro-electrolysis reactor. Hydrodynamic factors were optimized when the height-to-diameter ratio was 4:1

diameter ratio was 9:1

draft-tube axial height was 90 mm. Three-dimensional simulations for the water distributor were carried out

and the results suggested that the optimal conditions are as follows:the number of water distribution pipes was four

and an inhomogeneous water distribution was used. According to the results of the simulation

the suitable structure can be used to achieve good fluid mechanical properties

such as the good liquid circulation velocity and gas holdup

which provides a good theoretical foundation for the application of the reactor.
