摘要：在鼓泡塔内的热模实验表明,塔内存在一个适宜的液汽比。比较鼓泡塔和填料塔得出,完成相近的传热和传质负荷,鼓泡塔传热传质效率不及填料塔、鼓泡塔的蒸汽利用程度比填料塔高;鼓泡塔的操作弹性、设备堵塞等问题优于填料塔。故鼓泡塔亦是较理想的热水塔塔型,可用于水煤浆气化系统。
Thermal model research on heat and mass concurrent transfer process was made in a bubble column. The result shows that a suitable liquid-vapor ratio range is existed. In addition, bubble column was compared with packed column in some aspects. The result indicates that under the same operating condition, the heat and mass transfer efficiency of bubble column is not as well as that of packed column; the steam-utilized efficiency in bubble column is 15 percent more than that of in packed column; bubble column has better operation flexibility than that of packed column. Therefore, for the gray water recovery system in coal gasification process,bubble column is also a suitable type for hot water tower.
