摘要

目的为解决我国港口散粮旋流气力输送中现有装置能耗高、旋流衰减快、颗粒沉积等问题,本研究以小麦颗粒为输送对象,围绕涡流喷气式起旋装置的侧补气槽入口速度展开优化分析。方法基于建模软件SolidWorks构建涡流喷气式起旋装置三维模型,采用CFD-DEM双相耦合方法,在侧补气槽入口速度20⁓60 m/s范围内,分析管道内颗粒流动状态、旋流数以及压降特性。结果在侧补气槽入口速度为20⁓25 m/s范围内时颗粒动力不足导致沉降明显,在50⁓60 m/s 速度范围内时会由于速度冲击过大导致颗粒过度贴壁从而引发管壁磨损与颗粒破碎;而在侧补气槽的入口速度为30⁓45 m/s时颗粒分布较为均匀,旋流数下降幅度最小,此时起旋稳定,且压降梯度与能耗呈平衡状态。结论本研究明确了侧补气槽最优入口速度范围,为散粮旋流气力输送装置的结构优化与长距离输送能耗控制提供数据支撑。

Abstract

The work aims to analyze the optimization analysis of the inlet velocity of the side air-supplying slot of Vortex Jet-Type swirl generators with wheat particles as the conveying object to solve the problems of high energy consumption, rapid cyclone attenuation, and particle deposition of existing devices in the cyclonic pneumatic conveying of bulk grain at China's ports. After establishing the model of the Vortex Jet-Type swirl generator using the 3D modeling software SolidWorks, the CFD-DEM coupling method was adopted to analyze the particle flow pattern, swirl number, and pressure drop characteristics in the pipeline within the inlet velocity range of 20-60 m/s for the side air-supplying slot. When the inlet velocity was 20-25 m/s, insufficient particle kinetic energy led to significant sedimentation; when the velocity was in the range of 50-60 m/s, excessive velocity impact caused particles to adhere to the pipe wall excessively, thereby resulting in pipe wall abrasion and particle breakage. However, when the inlet velocity of the side air-supplying slot was 30-45 m/s, the particle distribution was relatively uniform, the swirl number showed the smallest decrease amplitude, and at this point, the swirl generation was stable, with the pressure drop gradient and energy consumption in a balanced state. This study identifies the optimal inlet velocity range of the side air-supplying slot, providing data support for the structural optimization of bulk grain cyclonic pneumatic conveying devices and energy consumption control in long-distance conveying.
