在φ500mm×8000mm的大型单射流半圆形流化床中，采用内径为42mm的半圆形射流管，以小米为实验物料，利用摄像法研究了射流气速、静床高度与射流深度的关系，得出了射流深度的定量关联式．藉PC—4光导纤维测浓仪，研究了大型射流流化床径向、轴向空隙率分布规律，最后得出了射流区各点空隙率分布的定量关系式．
In a large single-jet semicircular fluidized bed of φ500 mm × 8000 mm, a semi-circular jet pipe with an inner diameter of 42 mm was used to study the relationship between the jet velocity, the height of the static bed and the jet depth , Obtained a quantitative correlation of jet depth. By means of PC-4 optical fiber profilometer, the distribution law of radial and axial voidage of large-scale jet fluidized bed was studied. Finally, the quantitative relationship of voidage distribution at each point in jet zone was obtained.
