Abstract

Pneumatic conveying systems are widely used in the chemical and energy industries because they are highly efficient and environmentally friendly. However, issues such as pipeline blockages, high energy consumption, and wear on the pipeline walls continue to hinder their development. This paper provides a systematic review of research progress on pneumatic conveying systems for particles in pipelines. First, it introduces the flow field characteristics of dilute-phase and dense-phase pneumatic conveying, as well as the mechanisms of particle flow in pipelines. Then, it focuses on analyzing the coupled influence mechanisms of multiple factors, including solid conveying gas velocity, particle size distribution, moisture content, temperature, and pipeline parameters, on conveying efficiency and stability. To address issues such as particle deposition and blockage during conveying, the paper reviews solutions like double-tube-socket, optimized auxiliary air intake, and active flow field control. Based on these solutions, the paper proposes that future research should focus on dynamic coupling models of multi-physics fields and the analogies and extensions of gas-solid and gas-liquid models to promote the development of high-efficiency, low-energy pneumatic conveying systems. The paper provides a theoretical foundation for a deeper understanding of pneumatic conveying mechanisms and for optimizing engineering applications.

细、密相颗粒管道气力输送特点及影响因素综述

气动输送系统由于其高效、环保的特点，在化工和能源行业得到了广泛的应用。然而，管道堵塞、高能耗、管壁磨损等问题继续阻碍着其发展。本文系统地综述了颗粒在管道中的气力输送系统的研究进展。首先介绍了稀相和密相气力输送的流场特性，以及颗粒在管道中的流动机理。然后重点分析了固体输送气速、粒度分布、含水率、温度、管道参数等多因素对输送效率和稳定性的耦合影响机理。针对输送过程中颗粒淤积、堵塞等问题，本文综述了双管插座、优化辅助进气口、主动流场控制等解决方案。基于这些解决方案，本文提出未来应重点研究多物理场动态耦合模型以及气固、气液模型的类比和扩展，以促进高效、低能气动输送系统的发展。为深入了解气力输送机理和优化工程应用提供了理论基础。

期刊介绍： The word ‘particuology’ was coined to parallel the discipline for the science and technology of particles. Particuology is an interdisciplinary journal that publishes frontier research articles and critical reviews on the discovery, formulation and engineering of particulate materials, processes and systems. It especially welcomes contributions utilising advanced theoretical, modelling and measurement methods to enable the discovery and creation of new particulate materials, and the manufacturing of functional particulate-based products, such as sensors. Papers are handled by Thematic Editors who oversee contributions from specific subject fields. These fields are classified into: Particle Synthesis and Modification; Particle Characterization and Measurement; Granular Systems and Bulk Solids Technology; Fluidization and Particle-Fluid Systems; Aerosols; and Applications of Particle Technology. Key topics concerning the creation and processing of particulates include: -Modelling and simulation of particle formation, collective behaviour of particles and systems for particle production over a broad spectrum of length scales -Mining of experimental data for particle synthesis and surface properties to facilitate the creation of new materials and processes -Particle design and preparation including controlled response and sensing functionalities in formation, delivery systems and biological systems, etc. -Experimental and computational methods for visualization and analysis of particulate system. These topics are broadly relevant to the production of materials, pharmaceuticals and food, and to the conversion of energy resources to fuels and protection of the environment.
