Absorption tower with emergent spraying system

The invention relates to an absorption tower (1) with an emergent spraying system (8), wherein the emergent spraying system (8) comprises a high-position water tank (8a) positioned in a high position,a spraying pipeline (8b) and an emergent spraying close valve (8c); one end of the spraying pipeline (8b) communicates with the high-position water tank (8a); the other end of the spraying pipeline (8b) communicates with a flue inlet (6) of the absorption tower (1); the emergent spraying close valve (8c) is arranged to be near the flue inlet (6). The emergent spraying system (8) can obviously reduce the pipeline vibration and can prevent an interface flange from generating a water leakage phenomenon; in addition, the pipeline corrosion is limited in an extremely small region. 本发明涉及种设有紧急喷淋系统(8)的吸收塔(1)，该紧急喷淋系统(8)包括：位于高位的高位水箱(8a)；喷淋管路(8b)，该喷淋管路(8b)的端与高位水箱(8a)连通，另端与吸收塔(1)的烟道入口(6)连通；以及紧急喷淋关断阀(8c)，其中，紧急喷淋关断阀(8c)设置成靠近烟道入口(6)。该紧急喷淋系统(8)能够明显减少管道的振动、防止接口法兰出现漏水现象，并且将管道腐蚀限制在很小区域内。
