脱硫吸收塔除雾器喷淋优化

Spray Optimization of Mist Eliminator for Desulfurization Absorber

吸收塔除雾器是脱硫系统重要部件。除雾器的功能是把在喷雾吸收过程中,烟气夹带的雾粒、浆液滴捕集下来。除雾器的效率不仅与它自身的结构有关而且与雾粒的重度和粒径有关,喷嘴雾化粒径与吸收液黏度、喷雾爪力和喷嘴结构有关。把除雾器性能和雾粒直径配好,才能取得好的除雾效果。本研究从除雾器喷淋控制方面进行了讨论,结合实例,提升除雾器效率,减少设备结垢和堵塞风险,优化除雾器用水量以及在配置控制系统时的选择提供了一些建议。

Absorber demister is an important parts of desulfurization systems.The function of the demister is to capture the fog particles and slurry droplets enlivened by the smoke in the process of spray absorption.The efficiency of the demister is not only related to its structure but also to the weight and particle size of the fog particles.The nozzle atomization particle size is related to the viscosity of the absorber,the spray claw force,and the nozzle structure.When the performance of the demister and the diameter of the fog particle are well matched,can a good demister effect be achieved.In this study,the spray control of the mist eliminator is discussed,and some suggestions are provided for improving the efficiency of the mist eliminator,reducing the risk of fouling and clogging of the equipment,optimizing the water consumption of the mist eliminator and selecting the control system configuration.
