Research on Mercury Adsorption and Recovery Technology for Non-ferrous Metal Smelting Flue Gas
Nonferrous metal smelting flue gas mercury has the characteristics of high concentration and high content,and the traditional coal-fired flue gas mercury control technology can not meet the removal and recovery requirements.According to the zero-valent mercury in the flue gas of non-ferrous metal smelting,this paper analyzes and introduces the technology,proposes the system technology with mercury sulfate as the active absorption,and obtains the absorption efficiency of the mercury sulfate absorption system of up to 96.12％under the test of the fixed flue gas conditions.At the same time,the adsorption selectivity of heavy metal mercury ions in non-ferrous metal smelting was analyzed by using ZnS nano adsorbent,and the results of the technical application test showed that the application of ZnS nano adsorption technology can effectively remove mercury ions in the flue gas,and it has a higher value of application in the adsorption and recycling of the flue gas of non-ferrous metal smelting.
