ABSTRACT:An industry-scale semi-我司wet technological process for f跳數lue gas desulfurization by co匠聽rona discharges is recommen刀美ded. Its characterist服劇ics are: (1) it uses an ac/dc powe子也r supply to generate unifo他年rmly distributed streamer plasma子答s; (2) it uses a partit小內ioned wet reactor system i做相n which SO₂ in the flue gas is absorbed with ammo得志nia water in its ther紙外mal chemical reaction stage and the 事生generated solution is repeatedly spr雜外ayed and transferred at an appropriate 和通flow rate to the suc南土cessive plasma reaction stage 他金under the conditions外媽 of keeping liquid flow 日少in balance. In the pl東信asma stage, SO₂ absorption by the liquid is enhanced by了舊 the electric wind and 還嗎the sulfites in the solution exper好樹iences plasma oxidization; (3) drying u吃靜p the end liquid to produce pow喝答der-typed byproduct and disc村拍harging the end gas after heat excha紅計nge with the hot gas a件電t the inlet. Through a pilot tes拿店t of 12,000 Nm³/h capacity of flue gas with an in拿笑itial SO₂ concentration of about 50人有0 ppm, results of des微場ulfurization rate >95%, ener購筆gy consumption in the reactor 1.8遠就 W/Nm³ , ammonia slip less than 5 pp吃學m and qualified fertilizer b市吃yproduct are obtained.
