Description
Technical field
The present invention relates to the low dirty burning of coal high-efficiency and utilize field, especially relate to separating and method for quantitatively determining of carbon black granules and residual Jiao in a kind of burned-coal fly ash.
Background technology
Coal is the most widely used one in numerous energy, for instance in the power generation of China, and the electric power of nearly 70% is produced by coal fired power generation. Along with socioeconomic development, Chinese energy consumption presents the trend risen year by year.
In actual boiler fired coal process, due to the imperfect combustion of coal dust, unburned carbon (including carbon black granules and residual Jiao) can be formed, and be finally mingled in flying dust, both cause the waste of fuel, the pollution of atmospheric environment can be brought again. In unburned carbon, carbon black granules is the rich soot particulate matter of a kind of reunion shape superfine by the particle diameter formed by a series of complex reaction containing hydrocarbon gas precursor, and general diameter is less than 0.1 micron. Carbon black granules is difficult to be trapped by traditional dust arrester, once be discharged in air, namely becomes air PM2.5Important component part, environmental and human health impacts can be produced serious influence. Research shows, carbon black has strong extinction characteristic, is the second largest reason causing greenhouse effect. It addition, carbon black granules has extremely strong surface activity, it is possible to health is had by absorption air the pollutant of very big threat, such as carcinogenic, teratogenesis, mutagenic matter etc. Residual Jiao is pulverized coal particle imperfect combustion and the carbonaceous products that left behind, generally has loose structure, and diameter is more than 1 micron. In burned-coal fly ash, the existence of residual Jiao not only can reduce the transformation efficiency of coal, also can affect the serviceability of burned-coal fly ash, as when utilizing burned-coal fly ash to make cement, the higher meeting of phosphorus content causes that strength of cement declines, thus being unsatisfactory for demand of industrial production.
Traditional separation about carbon black granules in burned-coal fly ash and residual Jiao and quantitative approach rarely have report.Paul etc. (Fuel, 1987,66:210-215) report the burning using thermogravimetric analyzer to study residual Jiao, the existence of carbon black granules detected in experiment. But this method is only when the amount of carbon black granules is relatively larger, thermogravimetric analyzer just can have obvious signal; When the amount of carbon black granules is less, the signal of carbon black granules cannot be detected. And this method can not realize physical separation and the quantitative study of carbon black granules and residual Jiao. It addition, thermogravimetric analyzer price general charged is costly, mostly use in institution of higher learning and scientific research institution, less for using coal-burning power plant. (the CombustionandFlame such as Sadakata, 1984,56:245-249) propose the Submicron Particles (including carbon black granules) collecting in coal-fired process first by Andersen particulate matter ram, then use carbon in elemental analyser detection Submicron Particles, hydrogen content so that it is determined that the quality of carbon black granules. This method has bigger difficulty for actual coal-burning power plant, because it needs to use special sampling instrument that particulate matter is carried out isokinetic sampling, Andersen particulate matter ram is expensive on the one hand, sampling process is extremely complex on the other hand, personal error is relatively big, and residual Jiao in flying dust cannot be carried out detection by quantitative by this method.
Therefore, for assessing the utilizability of the impact on environment of the efficiency of combustion of coal dust, particulate matter of black carbon and burned-coal fly ash, it is highly desirable to the carbon black granules in burned-coal fly ash and residual Jiao are effectively separated and quantitative assay.
