HN3的安全性测试

利用一套安全测试系统,实验研究了电火花、加热和可见光照射作用下HN3的稳定性,结果表明HN3对电火花非常敏感,而对可见光很稳定,并且至少对小于530K的热作用具有很高的稳定性.     

基于物元模型的煤自燃危险性分析

为探索判断煤自燃的危险性新方法,在煤低温氧化试验的基础上,基于可拓理论构建了煤自燃危险性熵权和经验权的物元综合分析模型。采用该方法对4个不同煤样低温氧化试验数据进行自燃危险性分析,得出各煤样自燃危险性的等级及差异程度,并提出相应的防范对策。结果表明:4号煤样比其他煤样更具自燃危险性,需要重点防范。该方法的预测结果与实际情况相吻合。     

企业安全法规符合性评估方法

在安全法制建设逐步完善,安全法规数量逐年增多的背景下,为能有效落实企业安全生产主体责任,系统提出一种企业安全法规符合性评估方法:通过安全法规适用性辨识明确企业应满足的法规清单,对法规要求归纳汇总形成安全法规符合性定量评估指标体系,并以体系为依据对企业落实安全法规的程度进行科学评估、做好符合性保持.以某专业测井公司为例,构建了符合其生产经营特点的安全法规符合性评估体系,开发了基于B/S构架的辅助评估软件,并已应用于企业日常安全管理.结果表明:通过对安全法规要求分类归纳汇总形成的符合性评估指标体系,可有效评估企业安全法规落实程度,提高企业安全法规符合性评估效率.     

基于功率流的水泵隔振研究与控制

以某小区水泵隔振治理为例,应用功率流理论对水泵隔振系统中的参数对基础振动的影响进行研究.将水泵隔振系统简化为单层隔振系统的功率流隔振模型,依据电-力类比的方法,通过编写的Matlab应用程序,计算并绘制了质量块有无、质量块质量变化和基础区域面密度对传递到基础的功率流和振动速度的影响曲线.研究表明,质量块对基座的速度和功率流有明显的降低,增加质量块质量对幅值降低的影响不明显,增加基础区域面密度有利于隔振.     

NOx reburning in oxy-fuel combustion: A comparison between solid and gaseous fuels

In the development of oxy-fuel combustion, reburning of nitrogen oxides, recycled with the flue gases, has been investigated for primary NO_x control. Reduction of between 50 and 80% of the recycled nitrogen oxides has been measured. The present work evaluates the performance of gaseous and solid fuels as agents for reduction of nitrogen oxides by comparing experimental and modelling work performed at Chalmers University of Technology with different fuels. It is shown that the reduction is similar during propane and lignite firing, but that the lignite has slightly higher reduction efficiency. Differences in combustion temperature and heterogeneous effects are possible explanations.     

A New Approach of BioCO2 Fixation by Thermoplastic Processing of Microalgae

Effective sequestration of carbon dioxide (CO₂) by algae reduces greenhouse gases effect on global warming. Algae biomass or residual such as biomeal from algae biofuel processing can be judiciously used for industrial applications such as fertilizer, animal feed, and plastics. Conversion of algae into useful plastic materials can be accomplished by extrusion technology. During algal plastic manufacturing, up to 20% thermoplastic algal blends can be fixated into or encapsulated by a non-biodegradable polymer such as polyolefin, which is known to be resistant to abiotic or biotic degradation. As a result, CO₂ that is captured by algae through photosynthesis is permanently stored in a form of biomass and will not be released back into the atmosphere. The extrusion of microalgae reported in this article is a novel process to sequester CO₂ and at the same time it makes a good use of the algae biomass in plastic manufacturing. Mechanical properties of the thin plastic films containing microalgae are comparable to the neat polyurethane or polyethylene films. Injection molded articles containing microalgae are dimensionally stable. However, a lower tensile strength, especially elongation at break, is observed in comparison to the neat polypropylene.     

浅析报废汽车拆解厂废水循环处理技术的应用现状

报废汽车的回收拆解处理在我国已经逐渐兴起，但由于该产业尚处于发展初期，环保技术手段和可持续性发展意识还不够，因此在回收拆解过程中会产生大量的废水和其他污液。针对某汽车回收拆解厂的废水特性进行实验研究，形成“电荷凝集过滤一活性炭吸附”组合工艺，对报废汽车回收拆解企业的废水处理提供了一定的参考价值。
