摘要/Abstract

摘要： 在一台自行设计并搭建的新型螺旋式流态冰制取装置上，以醇类、盐类为添加剂加入制冰溶液，通过理论分析和实验研究制冰溶液特性对装置性能及流态冰产物的影响. 结果表明，在该装置上螺旋式流态冰制取方法是可行的，所得流态冰分布均匀，具有良好的流动性，最大含冰率可达13.68%，流态冰中冰晶颗粒一般呈条状和扁圆状，平均冰晶颗粒面积为10^-8~10^-9 m²；流态冰出口温度与制冰溶液添加剂种类和浓度有关，实测温度接近同种溶液过冷相变阶跃终点温度；同种添加剂时提高制冰溶液浓度会延长装置流态冰产生时间并降低出口冰浆温度，促使其含冰率升高；溶液浓度对产物流态冰中冰晶粒度的影响则因溶液种类和浓度不同呈现不同规律.

Abstract: A new dynamic ice slurry making apparatus named spiral scraping ice slurry generation was designed and developed by the author, on which the influence of different solution properties was analyzed theoretically and studied experimentally. In the experiment, alcohols and salts were used as additives in order to improve the solution properties. The results showed that the new apparatus could run steadily and could be easily operated. The ice slurry as product has good flowability, with a maximum ice packing factor of 13.68%. The ice crystal particles in ice slurry distribute uniformly, and generally present as strip or oblate, with an average area of between 10^-8 and 10^-9 m². The outlet temperature of ice slurry in the apparatus would be influenced by the additives category and concentrations of the solution, and the actual measured temperature is numerically equal to the end temperature of similar solution’s supercooling degree. In terms of the same additives, increasing concentration of the solution would extend the initiation time of apparatus producing ice slurry, reduce the outlet temperature of ice slurry and increase the ice packing fraction of ice slurry. The effect of additive concentration on the size of the ice crystal particles in ice slurry would show different laws when using different kinds and different concentrations of additives.

Key words: ice slurry, spiral scrape, additives, ice crystal particles, performance
