新一代硫酸装置干吸塔除雾器的选择

Next generation mist eliminator selection in sulphuric acid plant drying and absorption towers

介绍了在当前技术上作了重大改进的3种新型除雾器的开发。DEMISTER型713丝网除雾器，在干燥塔中使用可提高效率且具有较低的压力降；FLEXIFIBER BD-LdP布朗扩散型烛式除雾器，在吸收塔中使用可减小压力降且无效率损失；FLEXIFIBER ICK-LF碰撞型烛式除雾器，在干燥塔和二吸塔中使用可延长使用寿命且无效率损失。讨论了每一种类型除雾器的优点和局限性，以帮助管理者作出明智的决策，针对他们的具体要求选择最好的技术，同时也将比较不同选择所预期的安装、检修和操作费用。

Three newly introduced mist eliminators that offer significant improvements over current technology are described. DEMISTER style 713 knitted mesh mist eliminator provides increased efficiency with low pressure drop in drying towers, FLEXIFIBER BD-LdP Brownian Diffusion candle mist eliminator provides reduced pressure drop with no loss in efficiency in absorption towers and FLEXIFIBER ICK-LF impaction candle mist eliminator provides increased service life with no loss in efficiency in drying and final absorption towers. The benefits and limitations of each type are discussed to assist managers in making informed decisions about the best technology for their specific needs. It also compares the installation, maintenance and operating costs that should be anticipated for the various options.
