冲天炉消烟除尘及脱S设备工作原理

Working Principle of Cupola Smoke Dust Removal and De-sulphur Equipment

介绍了冲天炉熔炼铁液所排放污染物的含量,详细阐述了冲天炉消烟除尘脱S系统的组成及工作原理,包括:(1)捕集吸风口;(2)扰流式旋风冷却器;(3)高压脉冲袋式除尘器;(4)湿式脱S装置;(5)系统的远程控制。列举了国内一些工厂消烟除尘及脱S系统的使用效果,环保部门现场检测结果为:烟尘排放浓度均<40 mg/m^3;SO2排放浓度均<143 mg/m^3;氮氧化物排放浓度<150 mg/m^3。经治理后,在整个冲天炉熔炼过程中火花捕捉器无黑黄烟尘外溢现象,各项排放数据达标。

The content of pollutants discharged during cupola melting iron liquid was introduced.The constitution and working principle of cupola smoke dust removal and de-sulphur system was described in detail,including:(1)Capture suction vents.(2)Spoiler cyclone cooler.(3)High pressure pulse bag dust collector.(4)Wet de-sulphur device.(5)Remote control of the system.The application effect of smoke dust removal system and de-sulphur system in some factories in China was listed.The field test results of environmental protection department were as follows:smoke and dust emission concentrations were all less than 40 mg/m^3,SO2 emission concentrations were all less than 143 mg/m^3,nitride oxide emission concentration<150 mg/m^3.After governance,in the whole cupola melting process,there was no black and yellow smoke and dust overflow phenomenon in the spark catcher,all emission data were up to standard.
