链条炉中硫烟煤烟气除尘脱硫工艺设计

链条炉中硫烟煤烟气除尘脱硫工艺设计摘要这次的毕业设计是针对链条炉中的硫烟煤烟气除尘脱硫技术的研究，在了解和比较了不同的工艺过程后，根据不同的烟气脱硫技术，结合我国的排放标准，确定了相应的工艺方案。这次设计的工艺是通过布袋除尘器进行除尘和通过石灰石石膏法将烟气中的二氧化硫进行脱除，废气处理后，使其达到污染物的排放标准。按照给定的数据，算出各个设备的尺寸，再依据尺寸完成工艺流程图。关键词：锅炉；烟气除尘脱硫：袋式除尘；石灰石-石膏法脱硫AbstractThe graduation thesis design this time is the design of the sulfur bituminous coalflue gas dust removal and desulfurization process in the chain furnace,and theappropriate process is selected in accordance with the relevant national emissionstandards through the comparison of various flue gas desulfurization processes in thedesign of coal-fired boilers.In this design,the bag filter dust collector and lime gypsummethod desulfurization were selected,and the exhaust gas was treated to meet thepollutant emission standards.According to the given data,the size of each equipment iscalculated and the process flow diagram is completed.Key words:boiler;Flue gas desulfurization;bag dedusting;limestone-gypsum desulfurization2目录一.前言二.设计内容21.设计任务及要求22.设计原始数据23.设计主要内容三.烟气除尘技术41.湿式除尘42.袋式除尘3.静电式除尘54.烟气除尘新技术5四.烟气脱硫技术61.干法脱硫….62.氨法脱硫.…063.湿法烟气脱硫6五.选取除尘脱硫技术.…8六.物料平衡计算91.烟气量的计算92.烟气流量10七.除尘系统121.除尘系统的计算.121.除尘器的除尘效率122.除尘器的脱硫效率123.除尘器的烟气流量.122.除尘器的设计与计算…131.清灰方式的选择.132.滤袋面积143.滤袋数量.…144.滤室设计.145.进排气总管…146.进风口位置157.灰斗…158.除尘器高度159.脉冲阀163.管道直径及烟气流速.164.烟气系统..…161.烟囱几何高度…162.烟囱出口直径163.烟囱底部直径174.烟囱抽力设计.175.烟气的热释放率186.烟气抬升高度…187.烟囱高度188.烟囱位置185.压力损失的计算191.圆管摩擦压力损失192.局部阻力损失..193.烟囱阻力损失194.压力损失205.系统总损失….23八.脱硫系统.241.石灰石-石膏法脱硫原理..242。设计参数计算.243.脱硫效率...261.净烟气中S02的浓度.262.石灰石粉消耗量..264.烟气系统.27
