摘要
甲醛生产过程中,氧化后的甲醛气体经吸收塔吸收后,排放的尾气至尾气燃烧炉进行燃烧处理,普遍存在热效率较低的问题.本文通过对改变尾气燃烧炉结构形式及增加换热段换热面积的分析,提出了尾气燃烧系统的设计方案,同时对设备选型提出了相关要求,提升了甲醛尾气燃烧系统的热利用率.
Abstract
In the production process of methanol,the oxidized formaldehyde gas is absorbed by the absorption tower and the exhaust gas is discharged to the exhaust gas combustion furnace for combustion treatment,which generally has the problem of low thermal efficiency.This article proposes a design scheme for the exhaust gas combustion system by analyzing the changes in the structural form of the exhaust gas combustion furnace and the increase in the heat exchange area of the heat exchange section.At the same time,relevant requirements for equipment selection are put forward to improve the thermal utilization rate of the formaldehyde exhaust gas combustion system.
