流动结构对化学反应速率的影响
Impact of flow structure on reaction rate
摘要
Abstract
This paper introduces the concept of “cavitation impinging stream” with novel flow field structure and its background,describes the three features of “cavitation impinging stream”and analyzes its promotion of reaction kinetics. In order to verify the influence of flow field on chemical reaction rate,contrast experiments were conducted by using ordinary nozzle impinging stream reaction device,self-excited pulsed nozzle of cavitation reaction device,low-speed mixing device and high-speed stirring reaction device. When using cavitation impinging stream reactor, reaction rate constants were 13.42%,27.46%and 33.82%higher respectively than those of impinging stream reactor , high-speed stirring reactor and low-speed mixing reactor. Furthermore , energy consumption of the cavitation impinging stream reactor was lower. Cavitation impinging stream technology could effectively increase chemical reaction rate.关键词
