注射碱性干粉吸附剂脱除SO_3技术

Removal of SO_3 by injection of alkaline dry powder adsorbent

燃煤机组加装SCR脱硝装置后,烟气中SO_3浓度增加,引起空预器堵塞、烟道腐蚀、硫酸氢铵粘结除尘设备、烟囱蓝羽等问题。为了解决上述问题,并应对未来严格的SO_3排放标准,本文重点讨论了碱性干粉吸附剂注射技术。结果表明,该项技术是解决SO_3污染及相关问题的有效方法。

After the SCR denitration unit is installed in the coal-fred unit, the concentration of SO3 in the fue gas increases, causing problems such as air pre-blocking, fue corrosion, ammonium bisulfate bonded dust removal equipment, and chimney blue feather. In order to solve the above problems and deal with the strict SO3 emission standards in the future, this paper focuses on the alkaline dry powder adsorbent injection technology. The results show that this technology is an effective way to solve SO3 pollution and related problems.
