Design and Application of Structural Improvements in Composite Towers for Deep Desulfurization,Dust Removal and Fog Removal in the Ceramic Industry
摘要
Abstract
Ultra-net emission standards(particulate matter concentration below 5 mg/Nm3)for flue gases in the ceramic industry are implemented for the structural improvement of the interior components of deep desulfurization,dust removal and fog removal combination towers.The direct contact between flue gas and plasma is strengthened by the addition of a rotor coupling(turbulator)in the desulfurization system,accelerating the reaction rate of flue gas to plasma,and improving the desulfurizing capacity of the desulfurizer.Conventional dust and mist removal machines are replaced with piped dust and spray removal machines,rotor separators are added to the piped duty dust and air removal machines respectively.The speed increaser and the water retaining ring enhance the demisting and dust removal effect,further strengthen the flue gas sulfur removal efficiency of the desulfurization system,and reduce the concentration of the flue gas slurry droplets.The experimental data show that the improved system maintains the unit load unchanged at different cycle pump stations.The sulfur removal efficiency is improved by 2%,and the dust concentration in the flue gas is reduced to 2.10 mg/Nm3,which is much lower than the ultra-low emission standard of 5 mg/Nm3.The dust removal efficiency is improved by 11.31%,the outlet pressure difference of flue gas is increased by 1 040 Pa,and the total pressure difference of dust remover is increased by 11%.With the same operating conditions,the consumption of absorption plasma(apatite plasma)is reduced by 13.59%after the structural improvements.The dust concentration in the export flue gas is far below the ultra-low emission standard of 5mg/Nm3,and the removal efficiency of SO2 and dust has been significantly improved to meet the environmental requirements of ultra-clean emissions.It effectively reduces the pressure loss of the desulfurization system;great savings are made in desulfurization costs.关键词
