我公司早期就进行工业窑炉烟气除尘技术的研究开发,因当时国内外缺少价格合理、耐高温、能适用于燃煤窑炉及其他烟气除尘的材料且外配设备质量不过关,特别是滤料质量,一直没有得到推广。近年来,滤料等配套件生产技术得到很大提高,布袋除尘器在窑炉除尘技术中的缺点已经克服;同时,国家环保标准日益提高,新标准的出台,电除尘器已不能满足窑炉烟气排放的处理要求,布袋除尘器代替电除尘器已成为必然趋势;为此,我公司研究开发出新一代FDYL型窑炉专用布袋除尘器。 相似文献

Smoke emission factors, (i.e., the mass of smoke per mass of fuel burned), were measured in 11 separate experiments. The size distribution of the smoke particles was determined using a cascade impactor. The percentages of “black” carbon (also called “graphitic” or “elemental” carbon) and organic carbon have been determined for all the experiments as a function of particle aerodynamic diameter. Values in the range of 0.1%–0.2% are reported for the smoke particle emission factors for Douglas fir whole wood and plywood burning under well-ventilated conditions. Approximately 65% of the particles have aerodynamic diameters less than 1 μm. Douglas fir whole wood gave smoke emission factors in the range of 2%–3.5% when burned under poorly ventilated conditions representative of a building fire that is limited by air entrainment. For this case the size distribution was much broader, with substantial quantities of particles up to 5-μm aerodynamic diameter. For all ex periments, the black carbon content represented between 50% and 75% of the total mass of the smoke particles. The smoke emission factor for burning asphalt roofing shingles is reported as 12.1% with a black carbon content greater than 70%. Over half of the mass consisted of particles of less than 1-μm aerodynamic diameter. 相似文献

A model for calculation of radiative transfer in a layer of particles on a fiber filter that takes into account multiple scattering has been developed. It was shown that the model describes calibration curves for the black smoke method. Multiple scattering and variations in the black carbon fraction are the main factors that control complex relationships between substrate loading and optical response. It was obtained that on average for the UK the fraction of the black carbon decreased from about 23% in the 1960s to about 10% in the 1990s. An approach has been suggested to convert black smoke data into PM 10 . A new method of measuring PM 10 based on measuring light reflectance of two filters containing the same aerosol but different surface mass concentrations is suggested. The model can be applied to the integrating plate and other optical methods. 相似文献

以EVA为高分子聚合物,采用不同级别的导电炭黑,研究了导电炭黑填充高分子聚合物的导电性,讨论了不同级别和不同用量的导电炭黑在聚合物中的分散性,以及对高分子聚合物导电性的影响。实验结果表明,导电炭黑高分子聚合物的导电性主要取决于不同级别的导电炭黑的表面积和结构等特性、炭黑的不同用量以及导电炭黑的聚集体在高分子聚合物的分散程度。 相似文献
