This study investigates the size distribution of nano/ultrafine particle-bound PAHs (polycyclic aromatic hydrocarbons)
and the PAH-associated carcinogenic potency/cytotoxicity of the exhaust from a g...
柴油发电机驱动的热泵干燥系统开发与优化(Development and Optimization of a Heat Pump Drying System Driven by a Diesel Generator)
热泵干燥 柴油发电机 流化床
2009/11/3
设计了柴油发电机驱动的移动式热泵干燥系统,该系统由蒸汽压缩式热泵(热泵工质为R134a)提供热量,以卧式多室流化床为干燥室。在风道中设置换热器回收柴油机冷却水和烟气余热,以提高系统一次能源利用率。针对该系统建立了流化床、热泵、柴油发电机组耦合为一体的综合数学模型。数学模型计算结果表明:干燥室入口空气温度在60~90℃时,干燥系统的除湿能耗比先升后降,在70 ℃附近存在一个最大值。样机实验表明:设备...
