Description

一种带可调式文丘里洗涤器的脱硫除尘装置
                         技术领域
本实用新型涉及一种脱硫除尘装置,尤其是涉及一种带可调式文丘里洗涤器的脱硫除尘装置。
                         背景技术
目前采用的文丘里洗涤器和脱硫除尘塔串联的烟气脱硫除尘装置,文丘里洗涤器和脱硫除尘塔的结构设计为固定结构,处理的烟气量为一定值,操作弹性小。而实际处理过程中,由于锅炉等运行状况的不同,产生的烟气量不同,选用恒定处理量的脱硫除尘装置,当需处理的烟气量小时,由于气速达不到设计要求,处理后的烟气达不到排放标准,而当需处理的烟气量大时,文丘里气速太大造成系统阻力降大大增加,使整个系统无法运行。
                         发明内容
本实用新型提供了一种带可调式文丘里洗涤器的脱硫除尘装置,操作弹性大,可处理不同量的烟气,使烟气处理能力与运行成本最优化配置。
本实用新型的技术方案为:一种带可调式文丘里洗涤器的脱硫除尘装置,由文丘里洗涤器和脱硫除尘塔串接而成,文丘里洗涤器的喉部通过隔板分隔成二个大小不同的腔室,大小腔室分别由两蝶阀控制,并分别带有进液管,脱硫除尘塔的塔内排列不同开孔率的塔板,分别带有相应的供液系统。
所述的文丘里洗涤器的大小腔室的截面积比例为1.1~3∶1。
所述的脱硫除尘塔内不同开孔率的塔板交错排列。
本实用新型将文丘里洗涤器隔开形成大小两个文丘里洗涤器,脱硫除尘塔与文丘里洗涤器相匹配设计不同开孔率的塔板,通过操作组合,使整个脱硫除尘装置处理不同的烟气量时可调节,节省运行成本,效能达到最优化。当使用本脱硫除尘装置处理烟气时,烟气量大小变化范围可达30%~100%,即为普通脱硫除尘器的3倍;而同时保持99%以上的除尘效率和85%以上的脱硫效率。
                         附图说明
图1为本实用新型的结构示意图。
                       具体实施方式
如图1,一种带可调式文丘里洗涤器的脱硫除尘装置,由文丘里洗涤器1和脱硫除尘塔16组成,文丘里洗涤器1的扩散段9与脱硫除尘塔16的烟气入口10连通,文丘里洗涤器1的喉部通过隔板8分隔成二个大小不同的腔室,大小腔室的截面积比例按不同的塔及烟气处理量可设计为1.1~3∶1,该隔板8既可水平设置,也可垂直设置。大小腔室前分别设有蝶阀2和蝶阀5,蝶阀2和蝶阀5控制大小腔室通道的开闭。
大小腔室分别带有进液管3和进液管6,形成大文丘里洗涤器4和小文丘里洗涤器7二套装置。
脱硫除尘塔的塔板交错排列大开孔率的塔板13和小开孔率的塔板14,分别带有相应的供液系统11和12。处理少量烟气时,蝶阀2关闭,蝶阀5开启,烟气通过小文丘里洗涤器7初步净化后进入脱硫除尘塔16,此时开启小开孔率的塔板14的供液系统12,关闭大开孔率的塔板13的供液系统11,使整个工艺操作在低处理量下运行,节省运行成本、并保证高脱硫除尘效率。处理中等量烟气时,蝶阀2开启,蝶阀5关闭,烟气通过大文丘里洗涤器4初步净化后进入脱硫除尘塔,此时开启大开孔率的塔板13的供液系统11,关闭或开启小开孔率的塔板14的供液系统12,使整个工艺操作能满足处理要求,当需处理大量烟气时,蝶阀2、蝶阀5均开启,大文丘里洗涤器4、小文丘里洗涤器7同时对烟气初步净化后进入脱硫除尘塔,此时开启大开孔率的塔板13的供液系统11,关闭小开孔率的塔板14的供液系统12,使大开孔率的塔板13处于工作状态,而小开孔率的塔板14仅作为通道使用。
本实用新型可在处理烟气量为设计量的30%-100%时调节使用,使设备投资、运行成本匹配最优化,同时保证高脱硫除尘效率。
