High concentrations of non-ferrous metal smelting flue gas desulfurization method research

在对高浓度有色金属冶炼过程中,烟气是重要的污染元素,为了达到环境保护和有用元素的循环利用要求,相关专家学者对高浓度有色金属冶炼过程中的烟气脱硫进行了研究。传统的脱硫方法使用的是臭氧氧化控制技术,只能脱去烟气中的硫元素,但是产生的二氧化硫和氧化氮无法消除,产生二次污染。为此,提出一种氨法烟气脱硫法,在对高浓度有色金属冶炼烟气脱硫过程中,结合臭氧氧化工艺,通过间歇式密闭均相反应装置对烟气氧化动力进行催化搅拌,采用鼓泡反应对催化氧化烟气进行脱硫,及确定操作参数。仿真实验表明,提出的氨法高浓度有色金属冶炼能够实现有效脱硫,达到环保和金属元素循环使用的双重要求。

In the high concentration of non-ferrous metal smelting process, the flue gas is an important pollution elements, in order to achieve environmental protection and recycling requirements of useful elements, relevant experts and scholars of high concentration of flue gas desulfurization in the process of smelting non-ferrous metal are studied.The traditional desulfurization method is using ozone oxidation control technology, can only remove sulfur in flue gas, but the sulfur dioxide and nitrogen oxide can't eliminate, produce secondary pollution.Therefore, in this paper, a method of ammonia flue gas desulfurization method, the high concentration of non-ferrous metal smelting flue gas desulfurization process, in combination with ozone oxidation process, through the intermittent airtight homogeneous reaction device for catalytic oxidation of flue gas power stirring, using bubbling reaction of catalytic oxidation of flue gas desulfurization, and operating parameters.Simulation results show that the proposed method of ammonia concentrations smelting non-ferrous metal can achieve effective desulfurization, meet the requirements of environmental protection and metal elements cycle using the double.
