两段炉水煤气气化工艺含酚废水的处理

PROCESSING OF PHENOL DERIVED FROM TWO STAGE WATER GAS GASIFICATION PROCESS

两段炉水煤气气化工艺在上吹制气阶段产生含酚冷却（冷凝）水，下吹制气阶段，将脱除焦油、悬浮物、沉淀物并进一步过滤后的酚水加压、雾化、喷入燃烧蓄热室内与高温格子砖进行热交换，使之汽化并过热，然后与补充过热下吹蒸汽一起进入气化炉火层，酚在高温作用下分解成Ｈ２Ｏ和ＣＯ２，并进一步与炽热的炭发生反应，形成Ｈ２和ＣＯ．

Phenol derived from two stage water gas gasification is produced in upward, and in downward, after tar, suspension and sediment removed, phenol, which has been filtrated, pressurized and atomized, is sprayed into regenerative chamber where phenol and high temperature lattice bricks exchange heat each other and phenol get into superheated vapor, then phenol come into gasifier with making up steam and in fire layer phenol is decomposed into H 2O and CO 2 which will go on reacting with blazing carbon and form H 2 and CO finally.
