基于谓词逻辑的应急指挥系统的设计研究

世界各国在“9．11”事件以后都开始了应急指挥系统的设计和建设,我国也建立了不少的应急指挥系统,但是从近几年紧急事件的处理情况来看,这些系统有一共同的缺陷：对应急指挥系统的设计理论没有深入的分析,系统的设计没有明确的方向,也缺乏对应急流程的分析思考,忽视计算机的智能处理能力,造成应急指挥系统的使用低效。针对这两个问题,先阐述了应急指挥系统设计通用的理论原则,之后着重分析了应急流程的数字化问题,提出了一种以谓词逻辑为核心构建应急指挥系统的设计方法,解决了智能分析辅助指挥的关键问题。     

蒸汽抑制熄灭酒精池火有效性的模拟实验研究

蒸汽灭火系统在酒类作业场所有着广阔的应用前景.通过全淹没和局部保护实验对蒸汽抑制熄灭酒精池火的有效性进行了研究.实验结果表明,全淹方式难以有效控火,但是布局合理的局部保护方式能够有效熄灭酒精池火.蒸汽灭火过程中稀释O2浓度的灭火机理起到的作用较小,蒸汽的火焰拉伸效果是其主导灭火机理.     

Experimental study on flue gas purifying of MSW incineration using in-pipe jet adsorption techniques

This paper presents the experimental research process and results about flue gas purifying of municipal solid wastes (MSW) incineration using in-pipe jet adsorption techniques. MSW incineration was carried out in a fluidized bed test rig, and the flue gas purifying was carried out in an in-pipe jet adsorption test rig. The experimental results are as follows: when the feedstock of activated carbon is 1.6g/Nm(3), the desulfurization efficiency is 83%, the denitrification efficiency is 41%, and the dechlorination efficiency is 27%. The order of purifying effect of the three kinds of adsorbents on acidic gases from MSW incineration is activated carbon>activated bauxite>kaolin. Comparison of adsorption capabilities of the three kinds of adsorbents to heavy metals shows that activated carbon is the best additive to remove Cd, Pb and Cu, kaolin is inferior, and activated bauxite is the worst one. However, activated bauxite is the best additive to remove Hg, and it can remove Cd effectively. PAHs in fly ash are dominated by three-, four-, and five-ringed PAHs, and PAHs in the flue gas mainly include three- and four-ringed PAHs. When the injected quantity of additive is constant, the order of cleaning effect on PAHs is kaolin>activated carbon>activated bauxite. These three kinds of adsorbents have different purifying effects on acidic gases, heavy metals and PAHs in the flue gas from MSW incineration. In general, activated carbon has a better adsorption capability.     

Sorbents for CO2 capture from high carbon fly ashes

Fly ashes with high-unburned-carbon content, referred to as fly ash carbons, are an increasing problem for the utility industry, since they cannot be marketed as a cement extender and, therefore, have to be disposed. Previous work has explored the potential development of amine-enriched fly ash carbons for CO(2) capture. However, their performance was lower than that of commercially available sorbents, probably because the samples investigated were not activated prior to impregnation and, therefore, had a very low surface area. Accordingly, the work described here focuses on the development of activated fly ash derived sorbents for CO(2) capture. The samples were steam activated at 850 degrees C, resulting in a significant increase of the surface area (1075m(2)/g). The activated samples were impregnated with different amine compounds, and the resultant samples were tested for CO(2) capture at different temperatures. The CO(2) adsorption of the parent and activated samples is typical of a physical adsorption process. The impregnation process results in a decrease of the surface areas, indicating a blocking of the porosity. The highest adsorption capacity at 30 and 70 degrees C for the amine impregnated activated carbons was probably due to a combination of physical adsorption inherent from the parent sample and chemical adsorption of the loaded amine groups. The CO(2) adsorption capacities for the activated amine impregnated samples are higher than those previously published for fly ash carbons without activation (68.6 vs. 45mg CO(2)/g sorbent).
