通过实验发现不同直径的磁铁磁化铁丝后,在反应器内形成的特殊的磁场会对HCFC-141b制冷剂气体水合物的生成过程产生显著的影响.没有磁场作用时,水合物只在水相中生成.在磁场影响下,水合物的生长方向发生改变,可以先优先向水相或制冷剂相分别生长;在特殊情况下,水合物可以在制冷剂相的底部先生成;水合物的生长区域可以扩展为在水与制冷剂两相中生长.同时在磁场影响下,引导时间极大地缩短,可由9 h减小到最小40 min左右;生成质量显著增多,许多情况下水合率可以达到100％.此外,测出了磁场强度与引导时间和水合率的关系,初步得到了一些规律.
Through the experiments, it is found that the special magnetic field formed in the reactor after magnetized iron wire with different diameters can have a significant effect on the gas hydrate formation process of HCFC-141b refrigerant. In the absence of magnetic field, the hydrate is only in the aqueous phase Generated under the influence of the magnetic field, the hydrate growth direction changes, you can give priority to the water phase or refrigerant phase growth respectively; in special cases, the hydrate can be formed at the bottom of the refrigerant phase first; hydrate growth area Can be extended to grow in both water and refrigerant phases.At the same time, under the influence of magnetic field, the guiding time is greatly shortened from 9 h to a minimum of 40 min, and the mass of formation is significantly increased, and in many cases the hydration rate can reach 100% In addition, the relationship between the magnetic field strength and the lead time and the hydration rate was measured, and some laws were initially obtained.
