摘要

滚筒式、转鼓式、带式和流化床干燥机是常用的生物质干燥机，但由于其传热传质率低，能耗高。因此，喷泉床干燥机已在文献中提出，这已被证明是有效的干燥粗和细木屑。此外，干燥的木屑在炉中燃烧，废气被送入喷泉床干燥器，为干燥室和预热室提供热量。然而，操作参数和几何参数对喷泉床干燥机性能的影响至今尚未确定。因此，本研究建立了一个数学模型，解决了固体、废气和空气的非稳态质量和能量平衡。废气流量是影响最大的参数，其次是空气流量，锥角是影响最小的参数。

A model for predicting the performance and maximizing the drying efficiency of an innovative fountain bed dryer

Tumble, rotary drum, belt and fluidized bed dryers are commonly used for the drying of biomass, but their energy consumption is high due to their low heat and mass transfer rates. Thus, fountain bed dryers have been proposed in the literature, which have proven effective in the drying of coarse and fine sawdust. Furthermore, dried sawdust is burned in a furnace, and the exhaust gases are fed in the fountain bed dryer to provide heat to both drying and preheating chambers. However, the influence of operating and geometric parameters on the performance of fountain bed dryer has not been ascertained to date. Accordingly, a mathematical model has been developed in this study, which solves the unsteady state mass and energy balances for the solid, exhaust gases and air. The exhaust gases flow rate is the most influential parameter, followed by the air flow rate, whereas the cone angle is the least influential one.

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.
