(DAP/NPK)装置尾气洗涤系统改造

Renovation of Tail Gas Washing System of DAP/NPK Device

磷铵装置尾气主要成分为水蒸气,冬天形成大量"白雾"不易扩散,为满足国家日趋严格的环保排放标准,保证云南云天股份有限公司的可持续发展,对30万t/a磷铵装置进行技改,技改后,降低了尾气湿含量,消除了"白雾"现象。

The main component of the tail gas of the ammonium phosphate plant is steam,forming a large number of"white mist"in winter,which is not easy to diffuse.In order to meet the increasingly strict national environmental protection emission standards and ensure the sustainable development of the company,the branch company carried out technical transformation of 300000 tons of ammonium phosphate plant.After the technical transformation,the wet content of tail gas was reduced and the phenomenon of"white mist"was eliminated.
