为了减少工业用衣物烘干机的能耗,对现有烘干机存在结构不合理、能源利用不充分等问题进行了研究。为了提高烘干机工作效率,分别在烘干机入口、底部回流区以及出口添加挡板和遮板。选取出入口挡板角度和遮板高度为优化参数,分别改变入口挡板角度、遮板高度以及出口挡板角度,对相同入口条件下烘干机内部流场进行仿真,研究了不同参数下的流场特性。最后以烘干机内筒空气流通最快为目标,筛选出了最优的参数组合,优化后的烘干机流场结构趋于合理,烘干机内的空气平均流通速度提升了69%。分别对优化前和优化后的烘干机的烘干性能进行实验比较研究,结果表明,优化后烘干机内部流场结构趋于合理,在能耗不变的前提下,大大提高了烘干效率。
In order to reduce the energy consumption of the industrial clothes dryer, the problems of the existing dryer such as unreasonable structure and insufficient energy utilization have been studied. In order to improve the working efficiency of the dryer, the baffle and the shutter are respectively added at the dryer inlet, the bottom reflux zone and the outlet. The baffle angle and shutter height were selected as the optimization parameters. The baffle angle, shutter height and exit baffle angle were changed respectively. The flow field inside the dryer under the same inlet condition was simulated. The flow under different parameters Field characteristics. Finally, with the goal of maximizing the circulation of air in the dryer inner cylinder, the optimal combination of parameters was screened. The optimized dryer flow field structure tended to be reasonable, and the average air circulation speed in the dryer increased by 69%. The drying performance of the dryer before and after optimization was compared with the experimental results. The results show that the flow field structure in the optimized dryer tends to be reasonable, and under the premise of constant energy consumption, the drying performance is greatly improved effectiveness.
