利用袋式除尘器处理含湿量大或粘性较大的含尘气体,粉尘易粘附布袋一直是令除尘界头痛难题。国外曾尝试试用覆膜滤袋和对滤材表面进行防水处理解决防结露和布袋糊袋的难题,取得了明显的效果。

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明,烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的,当其浓度大于50×10^(-6)时,需要进行烟气脱硫或控制培养液pH变化来消除其影响;烟气中NO浓度不高于300×10^(-6)时,不影响ZY-1的生长及其对CO2的固定,反而可作为氮源供ZY-1生长用;对经过一般除尘处理的烟气来说,在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。

The finer sizes have lower minimum explosible concentrations and higher explosion intensity. When particle sizes of coal dust are less than 75 μm,minimum explosible concentrations and explosion intensity approach a limiting value. In the concentration range measured ( less than 700 g/m3), maximum explosion pressures, maximum rates of pressure rise and explosion indices increase along with the increase of coal dust concentrations. Explosion intensity rapidly enhances along with ignition energy augmenting. Explosion reaction is weak while ignition energy is less than 1 kJ.

煤粉越细,其爆炸下限越低,爆炸烈度越大,但煤粉细到75 μm以下后,这种变化趋势趋缓;在所测浓度范围内(小于700 g/m3),最大爆压、最大压力上升速率和爆炸指数均随煤粉浓度增大而增大;爆炸烈度随点火能增大而迅速增强,点火能小于1 kJ时各煤样在不同浓度的爆炸都很微弱。

Regardless to the research development or industrial application, nano metal powders are extensively discussed. Within these powders, the flammable and explosible nano aluminum, titanium and iron powders produce a great amount production and apply widely. Meanwhile, the surface/volume ratio of powders is increased significantly under nano scale, in which to enhance the ignition opportunity. Thus, the dust explosion hazard risk of nano powders could remarkable rise. In addition, the comparison of explosion phenomenon, test methods and quantification parameters between nano and micro scale is necessary to deeply investigate further. So that this project operates the explosion characteristic experiments to measure and determine such the maximum explosion pressure, minimum explosion concentration and explosion characteristic Kst value on above mentioned three nano metal powders. Expectantly, to provide the appropriate recommendations of safety prevention for nano dust explosion based on the experimental results.

奈米金属粉末无论是研究发展或是工业界应用,目前皆是广泛讨论研究之材料,其中,奈米铝粉、奈米钛粉以及奈米铁粉等可燃、爆性粉末,均有高额产量及大量应用领域,与此同时,在粉末粒径进入奈米尺度的情况下,粉尘比表面积大幅提升,增加此三种粉尘可被点燃的机会,因此,潜在的粉尘爆炸危害风险将广幅增加,另外,微米尺度粉尘爆炸的现象、测试方法以及量化参数是否具有相同的实验尺度基点,也需要深入探讨,故本次计画针对上述三种奈米金属粉末,进行三种不同粒径的爆炸特性参数实验,如最大爆炸压力、最低爆炸浓度以及爆炸特性参数Kst值之量测与计算,期能量化其粉尘爆炸特性,并据此提出适当的安全防护建议。
