淬火油劣化变质后排放处理难度大,一般通过再生处理延长使用期。对劣化淬火油进行两次混凝-活性炭吸附辅助再生处理,帮助降低劣化油中的杂质,并通过实验找到二次混凝-吸附的药剂配方及其最佳反应条件。实验得出,二次混凝的最佳工况条件为:最佳投药量2%和10%,最佳反应温度75℃和80℃,最佳搅拌时间8min和10min;吸附的最佳工况条件为:最佳投药量10%~14%,最佳反应温度100~110℃;最佳反应时间45min。再生处理后,油品的吸光度显著下降。
Quench oil deterioration metamorphic discharge treatment difficult, generally through the regeneration process to extend the service life. The coagulation-activated carbon adsorption-assisted regeneration process was applied to the degraded quenching oil to help reduce the impurities in the degraded oil. The secondary coagulation-adsorption formulation and the optimal reaction conditions were found through experiments. The experimental results showed that the optimum conditions of secondary coagulation were as follows: the optimal dosage was 2% and 10%, the optimal reaction temperature was 75 ℃ and 80 ℃, the optimum mixing time was 8min and 10min, respectively; The conditions are as follows: the best dosage is 10% ~ 14%, the best reaction temperature is 100 ~ 110 ℃; the best reaction time is 45min. After regeneration treatment, the absorbance of the oil decreased significantly.
