石灰石——石膏法烟气脱硫工艺
石灰石——石膏法脱硫工艺是世界上应用最广泛的一种脱硫技术,日本、德国、美国的火力发电厂采用的烟气脱硫装置约90%采用此工艺.
它的工作原理是：将石灰石粉加水制成浆液作为吸收剂泵入吸收塔与烟气充分接触混合,烟气中的二氧化硫与浆液中的碳酸钙以及从塔下部鼓入的空气进行氧化反应生成硫酸钙,硫酸钙达到一定饱和度后,结晶形成二水石膏.经吸收塔排出的石膏浆液经浓缩、脱水,使其含水量小于10%,然后用输送机送至石膏贮仓堆放,脱硫后的烟气经过除雾器除去雾滴,再经过换热器加热升温后,由烟囱排入大气.由于吸收塔内吸收剂浆液通过循环泵反复循环与烟气接触,吸收剂利用率很高,钙硫比较低,脱硫效率可大于95%

Answer 1

Limestone -- gypsum flue gas desulfurization limestone -- gypsum FGD technology is the world's most widely used of a desulfurization Technology,Japan,Germany,the United States used the thermal power plant flue gas desulfurization device about 90% use of this technology.It is the working principle :limestone powder,add water as a slurry made of absorbent absorber pump into full contact with the gas mixture The sulfur dioxide gas and slurry of calcium carbonate from the tower and the lower part of the drum into the air for oxidation reactions that produce calcium sulfate,Calcium sulfate is up to a certain saturation,the crystallization of gypsum.By the absorber from the gypsum slurry by thickening,dewatering,it is less than 10% moisture content.then sent to the conveyor stacking gypsum silo,the flue gas desulfurization through mist eliminator to remove droplet,After heat exchanger warming,from the chimneys into the atmosphere.As absorber within the absorbent slurry pump through a revolving cycle repeated contacts with the flue gas and absorbent utilization high,Calcium relatively low sulfur,desulfurization efficiency of greater than 95%
