对内回流循环流化床(RCFB)烟气脱硫系统二级电除尘器烟尘排放超标,改用高浓度布袋除尘器,运行后烟尘排放浓度小于50mg/m3(标准状态)。
2.
For this,the dust concentration in flue gas entering into the absorption tower has been decreased to 50 mg/m3,at the same time,the 50% dust removal efficiency of absorption tower isn\'t calculated again,this is reserved to treatment of the increased "spattered drops"of dust,to ensure the concentration of smoke emission to be less than 50 mg/m3.
对此,使进入吸收塔前烟气含尘浓度降低到50 mg/m3,同时不再计算吸收塔50%的除尘效率,而将其留给增加的"飞沫"粉尘的处理,以确保烟尘排放浓度小于50 mg/m3。

4)  Dust emission
烟尘排放
5)  smoke-density
排烟浓度,烟尘密度,排烟密度
6)  dust exhausting concentration
排尘浓度
1.
on the initial dust exhausting concentration of industrial boiler, and puts forward some corresponding methods and measures for reducing effectively the initial dust exhausting concentration of industrial boiler.
通过工业锅炉试验,分析研究了锅炉燃烧方式、煤种、锅炉负荷、过剩空气系数及运行操作等几种对工业锅炉初始排尘浓度有重要影响的因素,并有针对性地提出了一些能有效降低工业锅炉初始排尘浓度的方法和措施。
补充资料:林格曼烟尘浓度图
分子式:
CAS号:

性质:用比较法测定烟尘浓度时广泛使用的一种规格图。该图是由14cm×20cm,黑度不同的六小块图板组成,除全黑、全白外,其他四块是在白色背底上,涂上不同比例的黑色小格,使黑色小格占白色背色的百分比分别为20%,40%,60%,80%,由此把煤烟浓度相应地区别为6级,即0~5级。使用时将林格曼图板竖立在与观测者眼睛相同的高度上,然后在距离图板15m,距离烟囱40m处注视此板,与离烟囱口30~45cm处的烟尘浓度进行对比,即可得知烟尘浓度。使用时,观测者位置应与烟气流向成直角;不要面向太阳;烟气出口处的背景上不应有高大的树木和建筑物。级数烟气特点黑色小块占总面积/%烟尘量/(g/m3)0全白001微灰200.252灰400.703深灰601.204灰黑802.305全黑1004.0~5.0
