摘要

研究分别以砂子和煤灰为床料

含盐废液在流化床中焚烧

添加剂CaO、Fe2O3、A12O3对阻止床料结焦的作用机理.结果表明

当砂子或煤灰中形成Na2CO3时

CaO、Fe2O3能够解决床料的结焦问题

而Al2O3却促进砂子的结焦.当砂子中含有NaCl时

A12O3能很好地解决砂子的结焦问题

而CaO、Fe2O3虽然对防止结焦有效果

但不能根本解决砂子的结焦问题.当煤灰中含有NaCl时

CaO、Fe2O3对于防止床料的结焦效果较好

而A12O3反而造成严重结焦.研究结果为含盐有机废液在流化床中焚烧时防止床料结焦选择合适的添加剂提供理论依据.

Abstract

Experiments were conducted to investigate the influence of additives CaO

Fe2O3 and Al2O3 on bed sintering

while waste salty liquids are treated in fluidized bed with sand or coal ash as bed material. The results show that CaO and Fe2O3 can solve successfully bed sintering problems

provided Na2CO3 is formed in sand or coal ash bed

however

Al2O3 can cause serious bed sintering at bed temperature. If NaCl is formed in the sand bed

Al2O3 can solve successfully the bed sintering

CaO and Fe2O3 have some effect on preventing bed from sintering

but these two additives can’t solve the problem completely. If NaCl is formed in coal ash bed

CaO and Fe2O3 can solve successfully the bed sintering

however

Al2O3 can cause bad bed sintering. These results provide the base for the design and operation of fluidized bed incinerator for treating waste salty liquids.
