To understand the situation of the increasingly serious situation, master and management of industrial flue gas is imminent. How to stop the economic and efficient desulfurization and denitrification is a worldwide problem, at present alone desulfurization denitration technique is mature. Desulfurization techniques according to the classification of the important wet, dry, dry, semi dry process, more than two of the technology to establish a large number of desulfurization techniques, dividends paragraph, which set up in the process of the basic SCR is currently the mainstream techniques. Because the dry process has the advantages of high pollution, low energy consumption, small footprint, no two clean, easy operation and other characteristics are considered to be the most potential in the future of pollution technology. Dry desulfurization agent is an important activated carbon (coke), activated carbon (coke) pollution data in the industrial flue gas desulfurization and denitrification has a significant advantage, can be combined with the removal of pollutants, the application of low temperature, the air is less, but also to complete the use of sulfur and nitrate. At present, activated carbon in the country has been put into use, but its equipment investment and pollution costs are high. As for our country, different kind of activated coke is better than outside the area is big, the hydrogen and oxygen elements, pore structure and other characteristics of rich, for the desulfurization and denitrification supply beneficial premise, and the absolute carbon is cheaper, the activated coke to stop the implementation of more practical in our country. In order to obtain some new and Cheng Xinyi test results, we have to take the active coke to replace the active carbon materials to stop the desulfurization and denitrification. This paper has stopped the following research tasks: This paper discusses the technology of desulfurization and denitrification research background and the status quo, combined with the study of desulfurization and denitrification, the technology of desulfurization and denitrification technology to stop the test and analysis. The active coke was prepared by grinding, selection, activation, carbonization and other steps in the process of grinding, selection, activation and carbonization of Jincheng Shanxi anthracite and Eastern Yunnan. Through the process of flue gas desulfurization test to imitate two kinds of atmosphere, a self activated coke and activated coke desulfurization assessment is to stop trade. Research shows that two kinds of self activated coke S02 removal effect and the sulfur content in absolute trade activated coke is low, in the range of 100min, the trade of active coke desulfurization effect is higher than 55%. Through a selection of the desulfurization agent, the choice of the trade activity of Jiaozuo as the carrier to stop two times to improve the desulfurization and denitrification performance and the feasibility of combined desulfurization and denitrification. In the imitation of flue gas atmosphere, the KOH oxidation of the modified activated coke to stop desulfurization test. Research Notes: after KOH boiling 1H disposal, the active coke outside the functional group content, the effect of the desulfurization progress again, other, access to literature material, through the KOH oxidation, as well as the load of the amount of metal oxide activity in the middle. In order to further progress of active coke desulfurization denitration feasibility and function, in this study, the activated coke activated by KOH loaded on different metal oxides (Fe2O3, CuO, MnO2, CoO) and rare earth elements (Ce, La), the application of fixed bed flue gas separation system to stop pollution imitation desulfurization denitration evaluation results of comments: in the 2000ppm SO2; 5%O2 8000h-1, space velocity, reaction temperature of 120 DEG C under the premise of load 5%Fe2O3 and the activated coke load 5%CeO2 (Fe/ACKOH, Ce/ACKOH) has good de the space velocity 8000h-1, oxygen concentration 5%, NO concentration of 1000ppm, temperature of 80 DEG C, load 5%CuO and the activated coke load 5%Ce (Cu/ACkOH, Ce/ACKOH) show the best denitrification effect. Through the process of post test, using Fe/ACKOH and Cu/ACkOH to stop with desulfurization denitration test evaluation results, Cu/ACKOH notes, has the advantages of simultaneous desulfurization and denitrification effect, the space velocity of 4000h-1, flow rate 200ml/min, S02 concentration 2000ppm, NO concentration 1000ppm, the oxygen concentration of 5%, the premise reaction temperature of 80 DEG C, the desulfurization effect did effect in 99% of the pollution. In 45mmin, the removal rate of NO can be maintained at 40% above, through the process of reading the literature, SO2 has a restraint to the NO, and NO has an effect on SO2. The effects of Cu/ACKOH and Fe/ACKOH on the regeneration of active coke and the regeneration of water by ultrasonic wave were all maintained in the 20mmin, but the effect of Fe/ACKOH on 100min was 95%, and the removal efficiency of Cu/ACkOH was 35%. The recovery of active coke can be well, and has certain function of regeneration.目录:摘要4-6ABSTRACT6-8目录9-12第一章 绪论12-28&&&&1.1 研究背景12-13&&&&1.2 工业烟气脱硫技术13-20&&&&&&&&1.2.1 工业烟气湿法脱硫技术13-15&&&&&&&&1.2.2 工业烟气氨法脱硫技术15-16&&&&&&&&1.2.3 工业烟气循环流化床脱硫技术16-19&&&&&&&&1.2.4 工业烟气活性炭(焦)脱硫技术19-20&&&&1.3 工业烟气脱硝技术20-21&&&&1.4 工业烟气脱硫脱硝技术21-22&&&&1.5 工业烟气脱硫脱硝技术拓展22-24&&&&1.6 活性炭(焦)材料联合脱硫脱硝及再生24-26&&&&&&&&1.6.1 活性炭24-25&&&&&&&&1.6.2 活性焦25-26&&&&1.7 研究依据、内容26-28&&&&&&&&1.7.1 研究依据26&&&&&&&&1.7.2 研究内容26-28第二章 实验系统28-33&&&&2.1 实验原料、试剂及设备28-29&&&&2.2 技术路线29-30&&&&2.3 活性评价装置30-32&&&&2.4 气体配制及反应条件32-33&&&&&&&&2.4.1 气体配制32&&&&&&&&2.4.2 反应条件32-33第三章 自制及改性活性焦制备33-35&&&&3.1 自制活性焦33&&&&3.2 活性焦改性制备33-35&&&&&&&&3.2.1 KOH改性方法及步骤33-34&&&&&&&&3.2.2 负载金属及稀土元素方法及步骤34-35第四章 脱硫活性评价35-43&&&&4.1 实验原理35-36&&&&4.2 脱硫评价指标36&&&&4.3 结果与讨论36-41&&&&&&&&4.3.1 自制活性焦与商业活性焦脱硫评价36-37&&&&&&&&4.3.2 负载金属氧化物对活性焦脱硫效率的影响37-38&&&&&&&&4.3.3 负载稀土元素对活性焦脱硫效率的影响38-39&&&&&&&&4.3.4 Fe_2O_3负载量对活性焦脱硫效率的影响39-40&&&&&&&&4.3.5 反应温度对活性焦脱硫效率的影响40-41&&&&4.4 本章小结41-43第五章 脱硝活性评价43-50&&&&5.1 实验原理43&&&&5.2 脱硝评价指标43-44&&&&5.3 结果与讨论44-49&&&&&&&&5.3.1 KOH改性对活性焦脱硫的影响44&&&&&&&&5.3.2 负载金属氧化物对活性焦脱硝的影响44-45&&&&&&&&5.3.3 金属氧化物负载量对活性焦脱硝的影响45-46&&&&&&&&5.3.4 负载稀土元素对活性焦脱硝的影响46&&&&&&&&5.3.5 反应温度对活性焦脱硝的影响46-47&&&&&&&&5.3.6 氧含量对活性焦脱硝的影响47-48&&&&&&&&5.3.7 改性活性焦同时脱硫脱硝活性评价48-49&&&&5.4 本章小结49-50第六章 再生活性焦脱硫脱硝研究50-54&&&&6.1 加热实验条件50&&&&6.2 水洗超声脱附实验条件50&&&&6.3 结果与讨论50-53&&&&&&&&6.3.1 再生方法对Fe/AC_(KOH)脱硫脱硝效率的影响50-51&&&&&&&&6.3.2 再生方法对Cu/AC_(KOH)脱硫脱硝效率的影响51-53&&&&6.4 本章小结53-54第七章 总结与建议54-57&&&&7.1 总结54-56&&&&&&&&7.1.1 活性焦脱硫活性评价54-55&&&&&&&&7.1.2 活性焦脱硝活性评价55&&&&&&&&7.1.3 活性焦再生活性评价55-56&&&&7.2 建议56-57参考文献57-64致谢64-65附录A 攻读硕士期间的研究成果65-66附录B 攻读硕士期间参加的项目66-68原价：￥20.00元折价：￥5.00元分享到：相关文献|氨法脱硫技术运行总结_论文_百度文库
