废气处理装置
摘要：
本发明提供一种废气处理装置(10)是对来自锅炉(11)的废气(12)中所包含的NOx、Hg进行除去的废气处理装置，在锅炉(11)的下游的烟道(13)内具有：NH4Cl溶液供给机构(16)，其利用喷雾喷嘴(15)来喷雾NH4Cl溶液(14)；混合器(17)，其设置在NH4Cl气化的区域的下游侧，并促进NH4Cl气化所生成的HCl、NH3与废气(12)混合；还原脱硝装置(18)，其具有脱硝催化剂，该脱硝催化剂利用NH3将废气(12)中的NOx还原，并且在HCl共存下将Hg氧化；湿式脱硫装置(22)，其使用石灰石膏浆料(21)将在还原脱硝装置(18)中被氧化后的Hg除去。
摘要（英）：

The disclosed device for treating exhaust gas (10) eliminates NOx and Hg contained in exhaust gas (12) from a boiler (11), and has a NH4Cl solution supply means (16) that is in the downstream flue (13) of the boiler (11) and that mists a NH4Cl solution (14) by means of a misting nozzle (15); a mixer (17) that is provided downstream from the region wherein NH4Cl vaporizes and that promotes mixing of HCl and NH3, which are generated by the vaporization of NH4Cl; a reductive denitrification device (18) that has a denitrification catalyst that reduces NOx in the exhaust gas (12) using NH3 and oxidizes Hg in the presence of HCl; and a wet desulfurization device (22) that eliminates the Hg that had been oxidized by the reductive denitrification device (18) using a lime gypsum slurry (21).
