摘　　要：浮盘是覆盖在罐内储存介质上并随液面升降的盘状物结构,可以极大地减少罐内储存介质的挥发损耗,降低储罐发生火灾的风险。储罐不同收发油作业工况所引起的浮盘升降速度的变化会对浮盘运行的稳定性产生较大影响。文章通过利用两座工业尺寸储罐(容积300 m3,内径6500 mm)以及全浸液式浮盘,探究了不同升降速度条件下浮盘倾角的变化规律。实验发现在浮盘升降过程中,与储罐进出液口处于平行方向位置上浮盘的倾角较大,处于垂直方向位置处则几乎没有倾角,最大倾角出现在浮盘启停时。此外,浮盘升降过程中倾角的平均值与最大值的绝对值均与浮盘的升降速度呈现正相关关系。Floating plate refers to a disk that covers on the storage medium.It can significantly reduce the liquid volatilization loss and lower the fire risk of the storage tank.The rising and falling velocity of the floating plate varies at different operating conditions,causing the incline of the floating plate.In this study,the dip angle of the floating plate at different rising and falling velocities were investigated using two storage tanks(volume 300 m3,internal diameter 6500 mm)and a full contact type floating plate.It was found that the dip angles of the floating plate in the position parallel to the inlet/outlet pipe were relatively large while the dip angle in the position vertical to the inlet/outlet pipe were near to 0.The maximum dip angle occurred when the floating plate began to rise or fall.Besides,it was also found that the average and maximal dip angle of the floating plate were positively related to the rising and falling velocity of the floating plate.
