摘　　要：引言我国拥有世界上最为丰富的磷矿资源,黄磷的储量、产量和市场占有率均位居世界第一位[1]。黄磷冶炼过程会产生大量尾气,这些尾气富含一氧化碳,如能充分利用将是很好的化工原料。但由于黄磷尾气成分复杂、回收利用难度大且投资多,The recycling of yellow phosphorous tail gas rich in carbon monoxide is related to energy conservation and environment protection.Based on the analysis of existing technologies for the recycling of yellow phosphorous tail gas,a novel continuous process was developed by combining the resources recycling of yellow phosphorous tail gas with formic acid production,which made phosphoric acid acidification method as the core and could produce formic acid with high quality and low cost on the basis of considering the high and variable viscosity of system and the rationality of energy utilization.At the same time,a multilevel acidification reactor was also designed by integrating the reaction,heating and condensation reflux,which was divided into several reaction regions and equipped with different stirrers.The novel acidification reactor as the core equipment had the advantages of compact structure,energy conservation and wide adaptability.
