Abstract

本实用新型提供一种结构简单、成本低廉、提高燃烧效率和燃尽率的硫磺回收尾气焚烧炉富氧助燃装置。其技术方案为：空心装置（1）通过管道连接缓冲分液罐（2），缓冲分液罐（2）通过管道连接尾气鼓风机（3），尾气鼓风机（3）连接尾气炉（4），尾气炉（4）连接尾气管（5）。本实用新型提高了尾气炉焚烧效果，提高了燃烧效率和燃尽率，减少了CO2、NOX排放量；减少了助燃空气中的N2含量，降低了鼓风量，同时助燃空气中的氧浓度提高，促进燃烧完全，提高了燃料和氧气的利用率，降低了燃料燃烧消耗的空气量，降低了过剩空气系数；减轻了尾气净化单元的负荷，减少了烟气排放量。

Description

硫磺回收尾气焚烧炉富氧助燃装置
技术领域
本实用新型涉及化工技术领域，尤其是硫磺回收尾气焚烧炉富氧助燃装置。
背景技术
目前单纯的依靠空气压缩机或鼓风机为尾气炉提供常规助燃空气，不仅量大而且对燃料的要求也较高。同时炉内火焰温度难以提高，燃烧效率低，CO2、NOX排放量也大。
发明内容
本实用新型的目的就是针对现有技术存在的缺陷，提供一种结构简单、成本低廉、提高燃烧效率和燃尽率的硫磺回收尾气焚烧炉富氧助燃装置。
其技术方案是：空心装置通过管道连接缓冲分液罐，缓冲分液罐通过管道连接尾气鼓风机，尾气鼓风机连接尾气炉，尾气炉连接尾气管。
本实用新型有益效果：采用上述结构后，在相同配风条件下，使尾气焚烧炉火焰温度升高，提高燃烧效率，提高炉膛温度，增加热量利用率；促进燃烧完全，提高了尾气炉焚烧效果，提高了燃烧效率和燃尽率，减少了CO2、NOX排放量；减少了助燃空气中的N2含量，降低了鼓风量，同时助燃空气中的氧浓度提高，促进燃烧完全，提高了燃料和氧气的利用率，降低了燃料燃烧消耗的空气量，降低了过剩空气系数；减轻了尾气净化单元的负荷，减少了烟气排放量。
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所示，硫磺回收尾气焚烧炉富氧助燃装置，主要由空心装置1、缓冲分液罐2、尾气鼓风机3、尾气炉4和尾气管5构成；空心装置1通过管道连接缓冲分液罐2，缓冲分液罐2通过管道连接尾气鼓风机3，尾气鼓风机3连接尾气炉4，尾气炉4连接尾气管5。
本实用新型工艺：利用空分装置1制富氧空气，把收集的富氧空气经过缓冲分液罐2进行分液、压缩处理，然后连续稳定的输送至尾气炉4，使入炉助燃空气的氧含量提高至26%左右，在通过尾气鼓风机3增加与富氧空气的接触面积，使尾气炉4温度提高20℃-30℃，提高了燃烧效率，节约了燃料消耗。在尾气炉炉温和供风量控制系统中设置供风和燃料气联锁装置机构，安装回火截止阀和紧急切断装置，确保系统安全平稳的运行。尾气炉4助燃空气加入富氧空气后，焚烧效果得到大幅度提升。
