化工进展Chemical Industry and Engineering Progress2021年第40卷第12期涡轮自吸桨强化气液混合及氧化反应速率刘银领1,范兵强2,3,张喆1,郑诗礼2,3,张洋2,3(1天津大学化工学院,天津300354;2中国科学院过程工程研究所绿色过程与工程重点实验室,北京100190;3中国科学院过程工程研究所湿法冶金清洁生产技术国家工程实验室,北京100190)摘要:自吸式搅拌桨具有强化多相及均相体系混合的特性,被广泛应用于化工冶金等领域。
本文提出了一种新型涡轮自吸桨,并对其在混合及氧化还原过程中的强化作用进行了研究。
以电导率法作为测定方法,以混合均匀时间作为表征参数,对搅拌转速、搅拌输入功率、示踪剂添加位置、吸气和吸液混合等影响因素进行了系统研究。
研究结果表明,混合均匀时间随搅拌转速增加而降低,且存在临界转速,即为200r/min ,当搅拌转速大于临界转速200r/min 后,混合均匀时间基本维持稳定;当搅拌桨以吸气形式运转时,其他条件相同的情况下,自吸桨200r/min 转速的混合效果与常规搅拌桨350r/min 的混合效果相当;当搅拌桨以吸液形式运转时,自吸桨在0.27kW/m 3输入功率下可达到常规搅拌桨1kW/m 3以上输入功率的搅拌混合效果。
同时,本文以水杨酸为活性氧捕集剂,初步探究了自吸式搅拌桨在强化氧化还原过程的机理,研究结果表明自吸式搅拌桨在吸气运转过程中,混合搅拌体系产生了羟基自由基,对应羟基化产物在120min 后积累浓度为73.47μmol/L 。
此外,以二价铁为氧化剂受体,以二价铁的氧化效率为表征参数,对自吸式搅拌桨实际应用效果进行了系统研究,研究结果表明,在氧化二价铁的过程中,当pH 为5.0时,自吸桨氧化优于曝气氧化效果;在pH=4.0、常温条件下,相较于普通搅拌桨,自吸式搅拌桨对应体系的氧化效率达到30%,是常规搅拌桨的10倍;当转速大于300r/min 时,转速增加对氧化平衡终点影响较小,对氧化速率影响较大,即转速为400r/min 的氧化效率比300r/min 的氧化效率高30%。

在新型材料以及材料耐热性技术未能取得重大突破的情况下,冷却叶片技术成为解决高温问题的主要途径,冷却涡轮叶片结构也随着不同的要求变得越来越复杂[1-6]。
叶片结构参数化设计是涡轮冷却叶片自动化设计分析及优化的前提和基础[7-10]。
变壁厚气冷叶片结构设计比等壁厚叶片的更具有研究及应用价值。
虞跨海等[2]提出3次样条构造插值函数方法,以叶身外型构造函数建立叶型内外截面;宋玉旺等[5]提出基于离散数据点变壁厚直线插值方法,进行叶片变壁厚结构设计。
在应用变壁厚线性插值方法进行叶片变壁厚设计时,在叶型最大壁厚点处会出现拐点,即局部呈凹凸状,本文基于叶型离散数据点,提出1种变壁厚抛物线插值法,实现变壁厚气冷涡轮叶片参数化设计。
涡轮叶片叶型截面线和中弧线[11-12]如图1所示。
