Description

烟气强化脱硫塔
技术领域
本实用新型属于环保设备，涉及一种用于燃煤锅炉烟气净化的烟气强化脱硫塔。
背景技术
目前，对燃煤锅炉烟气主要采用脱硫塔作为净化设备，脱硫塔内一般设置有多级吸收处理段，为了保证脱硫效果，往往需要设置的净化级数较多，使得整个脱硫设备的占地面积和高度较大，不仅施工不便，并且设备成本较高。
发明内容
本实用新型所要解决的技术问题是，提供一种结构紧凑、体积小，同时能够保证脱硫净化效果的烟气强化脱硫塔。
本实用新型的烟气强化脱硫塔包括有一个多级的主脱硫塔及主脱硫塔前级的进气管道，该进气管道位于烟气进口和主脱硫塔进气口之间，它被分为管径依次变化的若干段，它们由前至后依次为加速管、等速管、减速管和连接管，所述加速管的管径由前至后逐渐减小，所速等速管为一段管径不变化的管道，所述减速管的管径由前至后逐渐增大，所述连接管是一段连接在减速段和主脱硫塔进气口之间的等径管道，在所述加速管后段设置有用来喷洒脱硫反应溶液的喷嘴。
本实用新型由于在主脱硫塔的进气管道上设置了预处理装置，使得烟气在进入主脱硫塔之前得到一定程度的脱硫处理，因而减小了主脱硫塔脱硫净化的工作量，因而可减少主脱硫塔的级数，减小设备的体积、降低设备成本。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图所示，该烟气强化脱硫塔的主脱硫塔1的进气管道2被分为多段，它们由前至后依次为管径由大变小的加速管3、保持较小管径不变化的等速管4、管径由小变大的减速管5以及保持较大管径不变化的连接管6。所述加速管3的后段设置有喷嘴7，它用来喷洒脱硫反应溶液。由烟气进口8进入的烟气经过各段管道，气速反复变化，使烟气与脱硫反应溶液能够更充分地接触和反应，进行初步脱硫后再由主脱硫塔进气口9进入主塔，减小了由主脱硫塔的工作量。
