Embodiment Construction
[0023] like figure 1 As shown, a novel cement kiln semi-dry desulfurization system of the present invention includes No. 1 cement kiln cyclone 22 and No. 2 cement kiln cyclone 1, which are arranged vertically in sequence and connected together through pipelines. The bottom of the kiln cyclone 1 is provided with a feeding pipe 2, and the lower part of the feeding pipe 2 is connected with a raw material bin 4, a lime slurry wet digester 5, a lime slurry storage tank 6, and a slaked lime water atomization injection system in turn through a pipeline 9 7. The end of the slaked lime water atomization injection system 7 is connected to the preheater 21 arranged on the upper part of the No. 1 cement kiln cyclone 22 through the pipeline 9 .
[0024] An air pump 3 is arranged on the pipeline 9 between the feeding pipe 2 and the raw material bin 4 .
[0025] The upper part of the raw material bin 4 is provided with a dust collector 8, the bottom side of the raw material bin 4 is connect...
