Denitration device for lime shaft kiln and lime shaft kiln

The utility model relates to a denitration device for lime shaft kiln and the lime shaft kiln, wherein the denitration device comprises a catalytic module arranged between a feed pipe and a kiln body of the lime shaft kiln, and an injection part arranged between the feed pipe and the kiln body, and the injection part is configured to be capable of injecting received denitration agent onto the catalytic module. And the flue gas generated in the lime shaft kiln can be subjected to selective catalytic reduction reaction with the denitration agent on the catalysis module before being discharged. Compared with the prior art, the denitration device and the lime shaft kiln are lower in construction and use cost. 本实用新型涉及一种用于石灰竖窑的脱硝装置及石灰竖窑，其中脱硝装置包括设在石灰竖窑的喂料管和窑体之间的催化模块，以及设在喂料管和窑体之间的喷射部件，其中喷射部件构造成能够将接收的脱硝剂喷射到催化模块上，以使得石灰竖窑内产生的烟气能在被排出之前在催化模块上与脱硝剂进行选择性催化还原反应。与现有技术相比，上述脱硝装置及石灰竖窑在建设和使用时所需的成本更低。
