Gas cyclone-liquid jet absorption separator used for treatment of tail gas containing HCl in titanium dioxide industry
文献摘要：
In the titanium dioxide industry,there is a lack of a low-cost and high-efficiency treatment method for chloride containing tail gas.In this paper,the removal of HCl from the titanium dioxide industry by gas cyclone-liquid jet separator was studied,while Ca(OH)2,Na2CO33,NaOH solution,and water were used as absorbents.This paper investigated the influence of gas cyclone-liquid jet separator's various process parameters on the removal rate of hydrogen chloride gas.The mechanism of mass transfer in the process of removing hydrogen chloride was discussed,and the effect and feasibility of HCl gas removal in the gas cyclone-liquid jet absorption separator were studied.The results showd that the removal efficiency of hydrogen chloride maintained above 95％,up to 99.9％,and the total mass transfer coefficient reached 0.28 mol·m-3·s-1·kPa-1.Under the same conditions,the absorption effect and total mass transfer coeffi-cient of weak basic absorption liquid can be greatly improved by increasing the flow rate of absorption liquid,but the absorption effect and total mass transfer coefficient of strong alkaline absorption liquid can't be improved obviously.The larger the inlet gas volume,the higher the gas concentration,the lower the absorption efficiency and the lower the total volumetric mass transfer coefficient.
