摘要
针对传统高COD含盐废水焚烧除盐冷却装置存在熔融盐析出堵塞换热器列管的问题,设计了刮板除盐方案,应用结果显示该技术解决了换热管堵塞问题,实现了高温烟气的快速降温,同时有效回收了高温烟气热量,副产蒸汽。
In order to solve the problem of blocking the heat exchanger tubes in the desalting cooling device of high COD salty wastewater combustion process,a scraper desalting scheme was designed.The results show that the application of this technology solves the problem of heat exchange tube blockage,realizes the rapid cooling of high-temperature flue gas,and effectively recovers the heat of high-temperature flue gas to produce steam.
