| 英文摘要 | In order to improve the liquid center aggregation of bubble-cap typed gas-liquid distributor in trickle bed reactor and investigate the relationship between structural parameters and performance of liquid distribution, a new gas-liquid distributor with the Venturi downcomer was designed while the effect of its structure parameters on the distribution quality was explored. A cold experimental bench was established, and the performance of the new gas-liquid distributor was verified. Euler-Euler-PBE mathematical model was built up and validated to simulate the gas-liquid flow in the new gas-liquid distributor. Combining the experimental and numerical data, the effect of the structure parameters on pressure drop, liquid distribution, and spray area was analyzed systematically. The results show that the use of a Venturi with a shrink-and-expansion structure as a downcomer can effectively improve the distribution uniformity and spray radius of the entrainment type distributor, and significantly reduce the pressure drop. Based on the orthogonal cases numerically, the significance of main structure parameters was clarified, and empirical correlations of the distribution performance with structural parameters were obtained. The expansion section of the downcomer is a key structure to improve the liquid distribution performance, and the liquid distribution performance is the best when the expansion angle is 30掳. 漏 2021, Editorial Board of CIESC Journal.
