Ejector is an important component of pneumatic conveying system and has important influence on the performance of pneumatic conveying system. For the design of the ejector, the system back pressure is generally calculated according to the layout of the pipeline, thus the ejector structure is pushed. On the basis of the comprehensive analysis of current injector theory and design method, the authors put forward a reverse design method of ejector. According to the actual system requirements, the design of the main structure of the injector was calculated by optimizing the structural design method. A 3d modeling tool was used to model the injector, FLUENT software, Euler model and discrete model were used to simulate the internal flow. Considering the influence of different structural parameters on the air transport injector, the static pressure cloud diagram and velocity cloud diagram of solid particles were obtained. The study indicates that the injector designed by the reverse design can meet the requirements of the pneumatic conveying system, and it can promote the application of the ejector in engineering.
