摘　　要：本文描述了城市生活垃圾与煤混烧后烟气利用流态化吸收式净化装置净化的试验研究结果。当吸收剂为石灰石浆液，浆液浓度１％，循环倍率为３，喷射速度为５～１５ ｍ／ｓ；鼓泡管插入深度１４０ ｍｍ时，流态化吸收式垃圾焚烧烟气净化装置的脱硫效率大于９０％，脱硝效率为２０～３０％之间，脱氯效率大于８０％，除尘效率大于９９％，重金属净化效率大于９８．６％，二恶英净化效率９９．３５％。This paper describes the result of experimental study of fluidized absorption process for flue gas purification in co-combustion of municipal solid waste (MSW) and coal. When the sorbent is limestone slurry, the concentration of slurry is 1%, the circulating rate is 3, the jet rate is 5-15 m/s and the immerged depth of bubbling pipe Under the slurry is 140 mm, in fluidized absorption facility for flue gas purification in MSW incineration, the desulfurization efficiency is > 90%, the deintrification efficiency is 20 - 30%, the dechlorination efficiency is > 80%, the removal efficiency of dust, heavy metal and dioxions are > 99%, > 98.6% and 99.35% respectively.
