Preparation and application of composite raw material melting accelerant
The invention discloses preparation and application of a composite raw material melting accelerator, and relates to the technical field of composite raw material melting accelerators, and the preparation specifically comprises the following steps: preparing a dispersion-assisting component, preparing a decomposition-promoting component, preparing a mineralizing component, preparing an air-entraining component, and preparing the composite raw material melting accelerator. Through introduction of the decomposition promoting component and the mineralization component, the surface structure of carbonate is destroyed, decomposition of carbonate is promoted, the carbonate and reactants form a solid solution and a eutectic mixture in the high-temperature calcination process, a liquid phase appears in the material at a low temperature, cement clinker sintering is promoted, and production energy consumption is reduced. Secondly, the gas-solid phase surface tension of gaps of the pulverized coal is reduced through an air entraining component, so that the pulverized coal diffuses and exchanges heat with the carbonate raw material in the spraying process, and the calcining atmosphere in a decomposing furnace and a rotary kiln is improved; and thirdly, the adding position of the admixture is optimized, and the acting effect of the admixture is improved.
本发明公开了一种复合生料熔解促进剂的制备及其应用,涉及复合生料熔解促进剂的技术领域，具体包括如下步骤：制备助分散组分、制备促分解组分、制备矿化组分、制备引气组分及制备复合生料熔解促进剂，本申请通过促分解组分和矿化组分的引入，破坏碳酸盐表面结构，促进碳酸盐分解，并在高温煅烧过程中与反应物形成固溶体，形成低共熔物，使物料在较低温度下出现液相，促进水泥熟料烧成，降低生产能耗。二是通过引气组分来降低煤粉间隙的气‑固相表面张力，使得在煤粉喷淋过程扩散与碳酸盐生料的换热，改善分解炉内与回转窑内煅烧气氛；三是优化外加剂添加位置，提高外加剂作用效果。
