摘要: 为分析实际生产中陶瓷滤管断裂的原因,利用电涡流位移传感器测定了陶瓷滤管在气体反吹时的振动,并测量了操作参数对陶瓷滤管振动的影响. 结果表明,陶瓷滤管在反吹时会产生径向位移,由于陶瓷滤管抗形变能力弱,可能会导致滤管发生断裂;另外,改变反吹压力对滤管振幅影响较大,反吹压力从0.3 MPa升至0.5 MPa时,滤管的振幅增加约40%;而改变过滤速度、脉冲宽度对滤管振幅影响较小,但会影响滤管振动的持续时间.

Abstract: In order to analyze the reason of rupture deformation of ceramic filter element, the vibration amplitude of ceramic filter element was measured by eddy current displacement sensor, and the influences of operational parameters on its vibration amplitude were measured. The experimental results showed that gas blowback would lead to radial displacement for the ceramic filter element, which maybe cause rupture deformation for ceramic filter element. In addition to, the influence of pressure of gas blowback on the vibration amplitude of ceramic filter element was obvious, if the pressure increased from 0.3 to 0.5 MPa, the displacement increase would reach 40%. However, the influence of filtration rate and pulse width on vibration amplitude can be ignored.

Key words: ceramic filter element, pulse cleaning, vibration amplitude
