Technical Problem
现有的脱硝设备中，催化剂大多采用网架的形式装配在烟气管道内，烟气通过网架时与内部的催化剂进行反应，但是上述的网架在使用的过程中容易对烟气内的灰尘过滤，使灰尘堆积在网架内，若是不能定期对灰尘进行处理，会影响烟气通过网架的通过效率，同时在对网架进行定期的更换与维护时，由于网架内堆积了较多的灰尘，在取出网架的过程中会造成灰尘向周围环境的溢散，从而对周围的环境以及相关的操作人员造成影响，容易危害操作人员的身体健康
Benefits of technology
[0008]与现有技术相比，本实用新型的有益效果是：一种干法脱硝设备内部清灰装置，与烟气管道内的催化方式相比，本实用新型将催化剂网架装配在装配机构内，在连接管道的底部设置有出灰斗，可以通过定期开启驱动组件，使装配机构带动催化剂网架在连接管道内进行往复动作，从而可以使网架内的灰尘进入到出灰斗内进行收集，减少灰尘对烟气通过率的影响，同时采用本实用新型可以在对催化剂网架进行更换前，对催化剂的网架进行除尘处理，使催化剂网架在移出连接管道时减少灰尘向周围环境中的溢散，避免灰尘影响到操作人员的身体健康。
