选用规整填料作为气液接触介质,以40%的LiCl-H2O溶液作为除湿溶液,通过数值模拟得到了填料塔尺寸(宽、高、厚)改变和保持填料体积不变的情况下填料尺寸(宽、高、厚)改变对除湿器性能的影响规律。理论分析表明,分别增加填料高度、宽度和厚度时,高度和厚度对除湿器性能影响较明显,而在保持填料厚度不变的情况下,高宽比大的填料塔性能要优于高宽比小的填料塔,高宽比为1.1~1.2时,除湿器性能处于较优的状况。
The structured packing was selected as the gas-liquid contact medium and the 40% LiCl-H2O solution was used as the dehumidification solution. The packing dimensions (width, height and thickness) were changed by numerical simulation and the packing size , High, thick) changes in the dehumidifier performance of the law. The theoretical analysis shows that the height and thickness of the packed dehumidifier significantly affect the performance of the dehumidifier when the height, width and thickness of the packed decks increase, respectively. However, when the packing thickness is kept constant, the performance of the packed tower with higher aspect ratio is better than the aspect ratio Small packing tower, aspect ratio of 1.1 to 1.2, dehumidifier performance in better condition.
