A test of the SXD-6 corrosion/ acid fume inhibitor used in steel pickling SXD-6型钢铁酸洗缓蚀抑雾剂试验结果及分析
After roasted in the multi-hearth, Ge residue was followed by acid washing and precipitating germanium with tannin, then the washed residue was treated in fume-off furnace and germanium was recovered from fume gas by hydrometallurgy at last. 先将锗残渣经多膛炉焙烧,然后酸洗,单宁沉锗,烟化炉处理洗涤渣,最后用湿法从烟气中回收锗。
Application of PLC in Acid Making Process by Smelting fume 冶炼烟气制酸生产过程中PLC的应用
Besides SO2 and NOx, the atmospheric pollutions also contain acid fog, malodorous gas, H2S, hydrocarbon, HF, HCl, asphalt fume, automobile exhaust, heavy metal, indoor pollution and so on. 造成大气污染的污染物除影响面广、排量较大的SO2和NOx外,还包括酸雾、恶臭、硫化氢、碳氢化合物、HF、HCl、沥青烟、汽车尾气、重金属、室内污染物等。
In the sulfuric acid plant of Jiangxi Copper Company Guixi Smelter, sulfuric acid is made using smelting fume from the flash furnace and the convertor. 江西贵溪冶炼厂硫酸车间利用熔炼车间闪速炉、转炉的冶炼烟气生产硫酸。
The collection efficiency of acid fume is increased because the humid surface of fibres and water droplets provide more opportunity of inertia-impaction and interception of fume particles with it. 纤维过滤层用喷雾将其封闭,由于纤维的湿润表面和微细水雾滴为酸雾粒子与其碰撞和截留提供了更多的机会,因而提高了酸雾捕集效率。
Development of device disposing innocuously of the acid fume from battery 蓄电池酸雾的无害化处理设备
Sulfuric acid fume on gaseous pollutants are extracted by microwave and analyzed by ion chromatography. The extraction time is shorter while the extraction rate is higher. 建立了一种以微波提取气态污染物中的硫酸雾,用离子色谱仪进行分析的方法,微波提取效率高,提取时间短。
