摘要
针对城镇集中供热锅炉房的特点,提出使用钙基脱硫剂的双液位喷射鼓泡烟气脱硫除尘装置。介绍了双液位喷射鼓泡烟气脱硫除尘装置的脱硫机理,实验分析了脱硫剂pH值对脱硫效率的影响、冲击管出口烟气流速对烟气压力降的影响,探讨了该脱硫装置的工业应用。使用钙基为脱硫剂的双液位喷射鼓泡烟气脱硫除尘装置,可减缓设备结垢,降低脱硫除尘成本,实现脱硫产物随灰渣一同处理。
Aimed at the characteristics of centralized heat-supply boiler room in cities and towns, a double liquid-level jet bubbling flue gas desulfurization and dust removal device using calcium-based desulfurizer is presented. The desulfurization mechanism of this device is introduced. The effect of pH value of desulfurizer on desulfurization efficiency as well as the effect of flue gas velocity at the outlet of impact tube on flue gas pressure drop are experimentally analyzed. The industrial applications of this device are discussed. This device can ease device scaling and reduce cost and achieve simultaneous treatment of desulfurization product and ash.
