摘　　要：在可视化低温实验台上研究了超声波对 HCFC- 14 1b(1,1- dichloro- 1fluoroethane)水合物结晶过程的影响 ,并对实验结果进行了分析讨论。结果表明 ,功率 116～ 80 0 W的超声波可促进面积为 19.6 cm2反应器中的水合物生成。在反应器面积增大至 38.5 cm2时 ,水合物结晶引导时间随超声波功率的升高而缩短 ,二者近似成对数关系 ,水合物结晶过冷度 Tf 从 7.9℃降低到 3.9℃。Crystallization characteristic of HCFC 141b hydrate under the effect of ultrasonic were studied in the video low temperature experimental system, and the results were analyzed and discussed. Results showed that ultrasonic of 116～800 W could speed hydrating process in the reactor with 19.6 cm 2 area. Induction times for crystallizing of hydrate shortened with the increase of ultrasonic power and there were approximately logarithm relation between them when area of the reactor increased to 38.5 cm 2. And the degree of supercooling ( T f ) decreased from 7.9 ℃ to 3.9 ℃.
