采用均匀设计试验方法,研究了微波处理低含油乳化液的脱油率与微波辐射功率、脱油温度、油的质量分数之间的关系,并应用MATLAB编程拟合出相应的经验公式,回归效果显著。结果表明,脱油率随微波辐射功率的增大呈负指数规律增加,随脱油温度的升高呈线性增加,随油的质量分数的增加呈2次关系减小;脱油温度与油的质量分数存在交互效应,含油率的升高会减小脱油温度对脱油率的影响,而脱油温度的升高会增大油的质量分数对脱油率的影响;当微波辐射功率为247.0 W/(60 mL)、脱油温度为90.4℃、油的质量分数为5.0%时,根据拟合公式得到静置30 min乳化液的脱油率达到最大22.21%。
The uniform design test method was used to study the relationship between the dewetting rate, the microwave radiation power, the dewetting temperature and the mass fraction of oil in the processing of low oil-containing emulsion by microwave treatment. The corresponding empirical formula was fitted by MATLAB programming and the regression effect Significant. The results show that the oil removal rate increases negative exponentially with the increase of microwave radiation power, increases linearly with the increase of the oil temperature, decreases with the increase of oil mass fraction. The relationship between the oil removal temperature and oil The interaction of the mass fraction exists, the increase of the oil content will reduce the de-oiling temperature on the de-oiling rate, while the increase of the de-oiling temperature will increase the oil mass fraction of the de-oiling rate; when the microwave radiation power is 247.0 W / (60 mL), the de-oiling temperature was 90.4 ℃, and the oil mass fraction was 5.0%. According to the fitting formula, the dewaterability of the emulsion reached the maximum of 22.21% after 30 min.
