摘要
在增压气力输送系统试验装置上,对影响收缩型气固喷射器的工作特性的关键因素做了较详细的研究.试验研究结果表明,气体喷嘴位置和收缩段的收缩角对气固喷射器的最大固体输送量均有较大的影响.此外,气体喷嘴位置以及收缩段的收缩角对收缩型气固喷射器内的静压分布也均有一定的影响.
On the testing equipment of a pressurized pneumatic conveying system, a detailed investigation of an important parameter, the location of driving nozzle, which can affect the conveying characteristics of the convergent gas-solid injector was performed. The experimental results indicate that the location of the driving nozzle and the convergent section angle has an obvious influence on the maximal mass flow rate of the conveyed material, and this effect has relation to the back pressure of the pneumatic conveying system. In addition, the location of the driving nozzle and the convergent section angle still affect on the static pressure distribution in the convergent gas-solid injector.
