ABS呢頻TRACT:An industry-scale semi-wet te這商chnological process for flue gas de動到sulfurization by corona disc山黑harges is recommended. It農照s characteristics are: (1) it 師山uses an ac/dc power supply to ge上些nerate uniformly dist日年ributed streamer plasma得通s; (2) it uses a partitioned弟這 wet reactor system in which SO₂ in the flue gas is absorbed with ammo信低nia water in its thermal 說又chemical reaction st跳筆age and the generated solution is re高電peatedly sprayed and transferred at a書也n appropriate flow rate to t時下he successive plasma reaction數我 stage under the conditions of子森 keeping liquid flow飛司 in balance. In the pla友市sma stage, SO₂ absorption by the liquid is enhanc得店ed by the electric wi冷分nd and the sulfites in t微山he solution experiences pla去師sma oxidization; (3) dryi媽空ng up the end liquid to produce powd和東er-typed byproduct an姐裡d discharging the end gas a微樹fter heat exchange with呢習 the hot gas at the inlet. Thr個多ough a pilot test of 12空短,000 Nm³/h capacity of flue gas with an initial腦長 SO₂ concentration of about 500 ppm, results下城 of desulfurization rate >95%, ene用金rgy consumption in the男鄉 reactor 1.8 W/Nm³ , ammonia slip less than 體水5 ppm and qualified ferti商開lizer byproduct are obtained.
