摘　　要：干法制粉是陶瓷行业重要的节能减排技术之一,但目前并未得到广泛应用。文中以南、北方各一家代表企业作为案例,针对干法制粉开展减污降碳协同增效评估。通过文献调研和实地考证,采用产排污系数法计算了干、湿法制粉技术大气污染物和CO_(2)减排量,并进行了对比分析。结果表明,与湿法制粉工艺(天然气)相比,同样生产1 t粉料,干法制粉可以减少51%的CO_(2)排放;同时大气污染物明显下降,其中颗粒物降低了42%,NO_(X)下降了45%,SO_(2)降低了42%。协同控制交叉弹性分析结果进一步表明干法制粉在减排大气污染物的同时可以实现较好的温室气体减排效果。由于南、北方原料含水率的差异,北方干法制粉能耗与南方相比下降51%,在原料含水率较低的北方应用干法制粉减污降碳效果更好。The dry-milling process is an important part of energy conservation and emission reduction technology in ceramic industry.However,it has not been widely applied.This paper evaluates the synergy between pollution reduction and carbon reduction of dry-milling process in the two representative enterprises in the south and the north of China.Through literature research and field research,the emission reductions of air pollutants and CO_(2)in dry and wet milling technology were calculated by product coefficient method.Compared with the wet-milling process,the same production of 1 t powder can reduce the CO_(2)emission by 51%of the dry milling technology.At the same time,the air pollutants can be significantly reduced,such as PM is reduced by 42%,NO_(X)is reduced by 45%,and SO_(2)is reduced by 42%.The cross elasticity of dry powder collaborative control is positive,which shows that dry milling can realize the synergistic emission reduction of air pollutants and CO_(2).Due to the difference in the moisture content of raw materials between the south and the north of China,the energy consumption of dry milling in the north decreased by 51%.The effect of reducing pollution and carbon by dry milling is better in the north with low moisture content of raw materials.
