Abstract

PURPOSE: To provide a simple ammonia stripping apparatus easy to maintain and check which apparatus is escapable from a clogging trouble even if cheap Ca(OH)2 is used as an alkali agent for double decomposition by feeding ammonia water to a plurality of reaction chambers in a horizontal type reaction vessel in order.
CONSTITUTION: Ammonia water is injected into first reaction chamber 161 from ammonia water injection pipe 17, and coal gas or the like is blown from gas blow pipe 13. By driving vapor-liquid contactor 12 free ammonia is stripped. The ammonia water is similarly treated in second reaction chamber 162 and fed into third reaction chamber 163, where an alkali agent for double decomposition, e.g. Ca(OH)2 is injected to double decompose fixed ammonia, which is stripped with contactor 12 and gas blow pipe 13. In fourth reaction chamber 164 ammonia is removed by similar treatment, and the treated water is fed to an ammonia water storage tank. The ammonia separated is gathered and recovered.
