Background
In the cement production process, in order to improve the whiteness of cement, a cooling and bleaching process is adopted, namely, the produced high-temperature cement clinker is rapidly cooled to about 550 ℃ in a water cooling mode, so that most of liquid phase in the clinker is not crystallized to become a glass body, and meanwhile, the water vapor generated by cooling ensures that the existing low-valence iron minerals in the clinker are not oxidized, thereby achieving the bleaching effect.
When the existing technology is used for bleaching the clinker, cooling water cannot be fully and comprehensively sprayed to the surface of the cement clinker, so that the clinker at high temperature is not uniformly cooled, and the cement clinker is insufficiently bleached; meanwhile, in the prior art, the quality of the produced white cement cannot be guaranteed due to the fact that the water spraying quantity cannot be guaranteed when bleaching is carried out, namely, the strength of cement clinker is reduced due to excessive water spraying, and the improvement of the whiteness of the cement is affected due to the fact that the water spraying quantity is too small.
