摘要
化工行业废气、废液综合治理的行业需求巨大。以某石化项目为例,结合该司锅炉设计运行经验,提出并设计了一种利用废气、废液焚烧产生的高温烟气加热多种介质的化工废气、废液焚烧余热炉。该余热炉根据传热特性合理布设多级受热面,实现对烟气热量的回收,提高了换热效率;针对废气与废液不同的处理温度,焚烧段设计了废气焚烧段与废液焚烧段,炉膛内设置浇注料隔墙与棋盘墙,可通过合理选取焚烧温度及烟气停留时间,保证废气和废液的焚毁去除率;烟气预热器为管箱式结构并在入口设置调温风,以控制废气出口温度。该设计思路可为其他废气、废液净化处理及焚烧炉设计提供借鉴及参考。
The demand for comprehensive treatment of waste gas and liquid in the chemical industry is enormous.Taking a petrochemical project as an example,combined with the company’s boiler design and operation experience,a chemical waste gas and waste liquid incineration waste heat furnace is proposed and designed to use high-temperature flue gas generated from waste gas and waste liquid incineration to heat multiple media.The incineration waste heat furnace is equipped with multi-stage heating surfaces based on its heat transfer characteristics,achieving the recovery of heat from flue gas and improving heat transfer efficiency;In response to the different treatment temperatures of exhaust gas and waste liquid,the incinerator is designed with an exhaust gas incineration section and a waste liquid incineration section.The furnace is equipped with castable partition walls and checkerboard walls,which can ensure the incineration removal rate of exhaust gas and waste liquid by selecting the appropriate incineration temperature and flue gas residence time;The flue gas preheater is a tube box structure and a temperature regulating air is installed at the inlet to control the outlet temperature of the exhaust gas.This design concept can provide reference and guidance for the purification and treatment of other waste gases and liquids,as well as the design of incinerators.
