火力發電廠SCR法煙氣脫硝技術

(典型應用項目:株洲攸縣煤電一體化項目一期工程2×600MW超臨界機組煙氣脫硝工程)

 

    公司科技人員自行研發的脫硝催化劑前端煙氣與氨均混技術突破了西方發達國家對煙氣脫硝技術的壟斷,該技術于2008年12月通過湖南省科技成果鑒定,以各項技術指標達到或超越引進技術而處于國際先進水平。具下列特點:

  ◆  基于FLUENT軟件平臺流體流場模擬,研究流體通過SCR反應器前的速度分布偏差、氨濃度分布偏差、溫度分布偏差、飛灰分布偏差來窺視煙氣與氨混合的均勻度以及飛灰的沉降規律;

  ◆  基于數值模擬結果,將煙道和SCR反應器按一定比例制成縮小的物理實物模型,進一步驗證數值模擬的準確度;

  ◆  基于流體數值模擬和實物模擬相互耦合驗證,優化SCR反應器核心部位煙道、噴氨柵格、導流板布置,以此指導和優化脫硝工程設計。使煙氣與氨混合達到最佳狀態;同步提高NOX的轉化率,降低氨的逃逸率;

  ◆  基于平衡SCR反應器熱脹冷縮對鋼結構產生的巨大推力,SCR反應器擬采用新型懸掛式結構;

  ◆  基于懸掛式結構選擇,用于制作和支撐SCR反應器鋼結構的鋼材量將同比下降10%;

  ◆  基于設煙氣旁路要求,采用防飛灰沉積的煙道和旁路擋板組合結構設計技術;
 
  ◆  基于準確煙溫檢測,以適時調節噴氨或停止噴氨來防止過量氨逃逸,降低脫硝過程的氨耗; 
 

  ◆  基于作業環境考慮,生產過程完全采用計算機自動控制。
