摘　　要：利用碱回收白泥制备轻质碳酸钙可以有效减少碳酸钙资源的浪费和环境的二次污染,但此项目的主要外购原料二氧化碳,因受市场因素的影响严重制约着该项目的正常运行。为此,在河南省龙泉集团实业有限公司的技术支持下,提出了对碱回收炉排放烟气中二氧化碳进行回收利用的方案,并将其运用到碱回收白泥制备轻质碳酸钙项目上,碱回收炉排放烟气中二氧化碳的含量在20左右,对其进行合理的回收利用,可减少资源的浪费和环境的污染。It can effectively reduce the waste of resources and secondary environment pollution to make precipitated calcium carbonate （PCC） using white mud from alkali recovery. However, carbon dioxide, the main outsourcing materials of this project, seriously restrict the normal operation of the project due to market factors, This paper proposed a scheme of recycling the alkali recovery furnace gas emissions of carbon dioxide. And it was applied to the preparation of PCC project using white mud. About 20% of the recovery boiler flue gas emission composition is carbon dioxide, reasonable recycling of it can effectively reduce the waste of resources and environmental pollution.
