摘要
以工业硫铁矿烧渣为原料,通过硫酸—盐酸混酸对硫铁矿烧渣中的铁进行提取,并选择合适的制备工艺,成功制备了高效的氧化铁脱硫剂。针对该型高效脱硫剂在工业有机废水脱硫工艺中的应用,重点考察了温度、水分、硫化氢浓度以及空速等工艺参数对脱硫剂活性的影响,并对脱硫工艺条件进行了优化。实验结果表明:温度对脱硫剂的硫容存在最佳值;在一定的湿度范围内,增大进气中水蒸气的含量,有利于脱硫剂硫容的提高;进气口中硫化氢浓度对硫容的影响不大,但会影响脱硫剂的使用时间;空速对脱硫剂硫容影响显著,空速越大,硫容越小。将制备的脱硫剂采用通入少量水蒸汽和稀氨水方式进行间接再生,累积硫容接近70%。
Extraction of iron from industrial pyrite cinder by using mixed acid was studied in past work. An efficient desulfurizer has been successfully prepared by choosing appropriate preparation technology. In this work, the technological parameters(temperature, moisture content, the concentration of hydrogen sulfide,space velocity)affecting the activity of desulfurizer were investigated for the application of the efficient desulfurizer in the biogas desulfurization process. The results show that: 1) space velocity has an obvious effect on the activity of desulfurizer and the sulfur capacity decreased sharply with the increase of space velocity. 2) the desulfurization increased along with the increasing moisture content within the scope of the inlet relative humidity less than 100%, and the sulfur capacity reached more than 35% when the vapor was close to saturation, therefore there existed an optimal moisture content. Besides, the sulfur capacity decreased as the moisture content reached supersaturation. 3) the sulfur capacity first increased then decreased as the temperature rises, and there existed an optimal temperature range.4) the sulfur capacity slightly increased following the concentration of hydrogen sulfide increased within a certain range. 5) the desulfurizer was indirectly regenerated by passing into air under the inlet condition that had water vapor and diluent ammonia,the accumulation of sulfur capacity was close to70%.
