东南大学热能工程研究所建立了我国目前最大的循环流化床烟气脱硫试验装置 ,脱硫塔直径 6 0 0mm ,处理烟气量达 2 0 0 0Nm3/h。文章在此试验台上进行了循环流化床烟气脱硫多层喷水的试验研究。试验表明多层喷水条件下 ,趋近饱和温度△T有较大降低 ,脱硫效率明显提高 ,提高了Ca的利用率 ,降低运行费用。
The Institute of Thermal Energy Engineering of Southeast University has established the largest circulating fluidized bed flue gas desulfurization test device in our country. The diameter of the desulfurization tower is 600 mm and the treatment flue gas volume is 20000 Nm3 / h. The article has carried on the experimental research on the circulating fluidized bed flue gas desulfurization multi-layer water spray on this test bench. Experiments show that the multi-layer water spray conditions, the approach temperature saturation △ T have greatly reduced, desulfurization efficiency was significantly improved, increasing the utilization of Ca, reducing operating costs.
