摘　　要：开发了一种新型聚羧酸减水剂预处理系统。取消了传统高位钢平台,采用低位投料和热水溶解大单体的方式,有效防止大单体成团现象,溶解和均化程度提高,采用电热水器、太阳能热水器和空气源热泵等设备复合产生加热源,比单一的电加热模式节约成本61%,节约标煤约6 500 t/年,减少二氧化碳排放量1.6万t/年。该系统可缩短其生产周期,减少生产人员和劳动强度,提高生产效率。Developed a new polycarboxylate pretreatment system. Canceled the traditional high steel platform and used low feed and hot water to dissolve large single way to effectively prevent large monomer into a group phenomenon,improve the degree of dissolution and homogenization, using electric water heaters, solar water heaters and air source heat pumps and other equipment to produce compound heating source, saving more than the cost of a single electrical heating mode 61%, saving about 6 500 t/year of standard coal and reduce carbon dioxide emissions by 16 000 t/year.The system can shorten the production cycle,production personnel and reduce labor intensity and improve production efficiency.
