基于主成分分析法的筛板式喷淋塔阻力特性影响因素研究

喷淋塔是石灰石-石膏湿法烟气脱硫装置的主要设备之一,对喷淋塔内部结构的优化研究一直是研究者们感兴趣的课题。为了探索筛板式喷淋塔内部的气液两相接触状态,采用空气-水作为介质,对孔径为6～30mm,开孔率为16%～48%的筛板进行了气液两相流动特性测试实验。利用SPSS软件,通过主成分分析法对筛板式喷淋塔的脱硫特性进行研究。主要针对筛板式喷淋塔的烟气流速、喷淋量、筛板孔径、开孔率等对阻力特性的影响进行研究。依据主成分分析法得出烟气流速、喷淋量和筛板孔径是影响筛板式喷淋塔阻力特性的最主要因素。

The study for influence factors of plate-type spray tower impact resistance properties based on principal component analysis

Spray tower is one of the main equipment of limestone-gypsum wet flue gas desulfurization devices.Researchers have been interested in the topic of the optimization of the internal structure for spray tower.In order to explore gas-liquid two-phase within the contact state for the plate-type spray tower,using air-water as a medium,the plate with aperture range of 6～30 mm,hole rate range of 16%～48% was tested in the gas-liquid two-phase flow characteristics.Using SPSS software,desulfurization characteristics of plate-type spray tower were studied through the principal component analysis.The impact of the plate-type spray tower＇s flue gas flow rate,spray volume,aperture plate,opening rate on resistance characteristics was studied.Based on principal component analysis,it was found that flue gas flow rate,spray volume and the aperture plate were the most important factors influencing resistance properties of a plate-type spray tower.
