| 中文摘要 | An approach of deconvolution by the Fast Fourier Transform (FFT) is applied to analyze the tracer response for evaluation of residence time distribution (RTD) from the raw data obtained in a double run of tracer experiments. A novel intuitive technique of coordinated smoothing in the frequency and time domains is tested for its accuracy and compared with the literature-reported method of regularization for measurement noise filtering. Tracer experiments were performed in 75 mm I. D. trickle bed packed with 2.7 mm glass beads, and RTD charts sampled in the trickling flow regime indicate that serious maldistribution of liquid trickling flow and hydrodynamic multiplicity exists even for a trickle bed with the ratio of height to diameter being up to 10. Using FFT deconvolution with coordinated smoothing to remove the interference originated outside the packed section seems to be effective and necessary for analysis and interpretation of tracer experiments. |
