一种Y型SCR系统催化剂在线连续再生装置
摘要：
本发明提供一种Y型SCR系统催化剂在线连续再生装置，包括：一第一SCR反应器及一第二SCR反应器；一烟气入口管道；一烟道切换结构，具有一第一工位及一第二工位；处于第一工位时，烟气入口管道与第一SCR反应器连通；处于第二工位时，烟气入口管道与第二SCR反应器连通；连接第一SCR反应器的第一催化剂再生系统；连接第二SCR反应器的第二催化剂再生系统。能够在机组不停机的前提下，实现脱硝催化剂的在线再生，减少机组因SCR催化剂活性下降导致的被迫停机，提高机组的经济安全运行水平。从而节省SCR系统的运行成本。
摘要（英）：

The invention provides a Y-shaped SCR system catalyst online continuous regenerating device. The Y-shaped SCR system catalyst online continuous regenerating device comprises one first SCR reactor and one second SCR reactor, one smoke inlet pipeline, one flue switching structure provided with one first station and one second station, a first catalyst regeneration system connected with the first SCR reactor and a second catalyst regeneration system connected with the second SCR reactor, wherein the smoke inlet pipeline is communicated with the first SCR reactor when the flue switching structure is at the first station, and the smoke inlet pipeline is communicated with the second SCR reactor when the flue switching structure is at the second station. The Y-shaped SCR system catalyst online continuous regenerating device provided by the invention has the advantages that online regeneration of a denitration catalyst can be realized without halting a machine set, forced halt of the machine set due to SCR catalyst activity decrease is reduced, and economic security and operation level of the machine set are improved, so that operation cost of an SCR system is saved.
