双回路烟气脱硫除尘装置的工业应用

Industrial Application of Double-cycle Flue Gas Desulphurization Device

文章介绍了双回路烟气脱硫除尘装置的工作机理,提出了双回路烟气脱硫除尘装置,并在20 t/h的供热锅炉房进行了烟气脱硫改造的工业应用。采用双回路烟气脱硫除尘装置,可实现脱硫除尘的灰水及碱液的分别独立循环,灰渣中不含脱硫剂,不影响灰渣的再利用。该系统不设沉降池,不增加占地面积,可以在原有锅炉房基础上实现烟气脱硫改造,特别适用于面积紧凑城区旧锅炉房烟气脱硫改造。

a double - cycle flue gas desulphurization device is introduced and flue gas desul- phurization transformation is done in the 20 t/h boiler in a heating boiler plant. The double - cycle flue gas desulphurization device can bring about separate dedust water and lye cycle. After desul- phurization, boiler ash residue contains no desulpburizer and can be reused. Flue gas desulphuriza-tion transformation can be done on the basis of the existing boiler room. Therefore, the double - cy-cle flue gas desulphurization device is particularly suitable to use in a small occupation area boiler room.
