用人工神经网络方法预测鼓泡塔气含率

A new correlation for the prediction of gas hod up in bubble columns was proposed based on an extensive experimental database set up from the literature published over last 30 years .The updated estimation method relying on artificial neural network,dimensional analysis and phenomenological approaches was used and the model prediction agreed with the experimental data with average relative error less than 10%.     

磷块岩浮选机的放大方法研究(Ⅰ)——实验室扩试确定放大准则

在12立升充气搅拌式磷块岩浮选机和12立升自吸搅拌式磷块岩浮选机的传递特性研究以及验证两区综合模型的合理性基础上,提出了磷块岩浮选机放大的准则是传质条件相似(k_La)_1=(k_La)_2和悬浮条件相似(W/V_F)=(W/V_F)_2。     

充填浮选柱捕集区气含率的试验研究

通过冷模试验方法考察了充填浮选柱捕集区的气含率，经试验数据回归分析，气含率εｇ＝０．０９６Ｊｇ０．９１（Ｈｃ／Ｄ）－０．１８。并结合漂移通量的理论，确定充填浮选柱的捕集区为近似均匀鼓泡流。     

秸秆蒸汽汽爆、固态发酵处理结合快速热解制液体燃料

为了改善生物质热解油的品质,引入了蒸汽汽爆、固态发酵对生物质进行了分级处理脱除其中半纤维素和纤维素,降低了生物质的羧基和羟基含量.研究了生化处理改变生物质组分对其快速热解及其热解产品的影响.结果表明,汽爆、发酵处理使得焦产率增加,油产率略有增加,热解气产率降低;除汽爆处理增加了CO2外,汽爆、发酵处理对热解气形成的规律影响较小;汽爆、发酵处理脱除半纤维素、纤维素后,醋酸降低了36%～49%,羟基丙酮减少了25.0%～38.5%,而酚类产物明显增加.油品的热值也由原麦秸的16～17MJ/kg增加到22～24MJ/kg.     

中空纤维超滤膜去除乳酸钙中蛋白质的研究

发酵法联合生产乳酸-乳酸钙工艺中,分离出的乳酸钙产品含有蛋白质、还原糖、重金属等杂质,影响产品的品质。本实验研究了中空纤维膜对乳酸钙中蛋白质的去除,并分析了压差、温度、浓度及pH值等因素的影响。得到了较好的工艺操作条件为Δp=0.05MPa,Δ=30g/L,30°C,pH=4。进一步提出用多步超滤能提高蛋白质的去除率15%～27%。     

着色塑料薄膜在蔬菜保护中的应用

介绍PVC黄色自粘薄膜和LKPE银色地膜在蔬菜，花卉和其他经济作物植物保护，虫情疫报中的应用，利用着色塑料薄膜产生的反应光，达到对害虫行为和生理的影响使害虫忌避并诱集杀灭。试验证明，这是一种无毒无害的植保方法。对保护环境，生产无公害蔬菜，大幅度降低农作物的生产成本将产生巨大的经济效益和社会效益。     

Flow of gas-liquid-solid system and its application in packed flotation column

A packed flotation column, which is packed with multiple board ripple packings, was described. Based on comprehensive steady state models, chemical reactor developed previously in chemical engineering subjects, have been extended to packed flotation column for mineral separation. The experimental results verify that tarts in series model is better than axially-dispersed plug flow model to describe flow pattern in the collection zone of column by RTD (residence time distribution), and the error of experimental data and calculated data of both models are 0. 07 % - 0. 1% and 0. 18 % - 0.45 % respectively. And, RTD of gas phase was also considered, results also show that gas in the whole column appears plug flow. The cleaning process through adding wash water in froth zone of column was described, and the effect of superficial air vdodty and superficial wash water vdocity on the cleaning action of froth zone were discussed. Flotation experiment for single column was conducted for phosphate ores. The recovery for P2Os was 85.8%, and the grade was 26.8%.
