Embodiment approach 1
[0057] figure 1 Showing the first embodiment of the manufacturing apparatus of cement clinker of the present invention, figure 2 Indicates its modified example.
[0058] Such as figure 1 As shown, the first embodiment has a rotary kiln 1 for firing cement raw materials, and a preheater 3 for preheating cement raw materials is arranged in series at the kiln tail 2 on the left side of the figure of the rotary kiln 1 , the kiln front 24 on the right side of the figure is used to heat the main burner 19 inside, and the kiln front 24 is used to cool the clinker cooler 20 of the fired cement clinker. The chute 5 of the cyclone separator 4 of the lower section takes out the take-out pipeline 6 of the cement raw material, the firing furnace 8 connected with the take-off pipeline 6, and the above-mentioned cement raw material fired in the firing furnace 8 is returned to the rotary The return pipeline 9 of the kiln tail 2 of the kiln 1 is roughly constituted.
[0059] Among them, t...
Embodiment approach 2
[0074] image 3 Shows the second embodiment of the manufacturing apparatus of cement clinker of the present invention, for the figure 1 The same structural parts shown are similarly attached with the same symbols and their descriptions are simplified.
[0075] Such as image 3 As shown, in the second embodiment, in a cement clinker manufacturing apparatus having a rotary kiln 1, a preheater 3 including a four-stage cyclone separator 4, a calciner 21, etc., as a firing facility 7, a A waste fuelization system for pre-treating chlorine-containing combustible plastic waste and introducing it into the rotary kiln 1.
[0076] The sorting device 25 provided on the most upstream side of the waste fuelization system is installed in the waste fuelization system. The sorting device 25 separates the combustible plastic wastes to be processed into wastes with a high chlorine content such as polyvinyl chloride and polyvinylidene chloride (hereinafter referred to as chlorine-containing p...
