摘要
介绍了新型燃煤烟气干法脱硫并回收硫技术的工艺流程概念。其特点是利用可再生煤基脱硫剂细粉进行干法连续脱硫， 脱硫过程在下喷式气流床中完成； 采用间接换热式脱硫剂热再生， 生成含高浓度二氧化硫的再生气体； 加压、冷却再生尾气， 其中的二氧化硫液化并与其它气体组分相分离， 进而生产液体二氧化硫副产品； 并介绍了烟气脱硫、脱硫炭再生和再生尾气液化的单元试验研究结果。
A new technical process concept is introduced by using dry flue gas desulfurization and recovery the sulfur. Its feature as follows; the dry desulfurization process can be conducted continuously by using the coal based fine sorbent that it can be regeneration; desulfurization process is completed at the down spurt type entrained bed reactor; indirect heat exchanger was adopted; desulfurization sorbent regeneration and to produce a tail gas which The sulfur dioxide content is higher; the sulfur dioxide can be liquefied and separated with other gases through compressing and cooling down the regeneration tail gas and to produced liquid SO 2 as by product. The unit experiment results as mentioned above are also introduced.
