摘要
为实现航运业CO2的减排,探究了膜丝填充率、膜丝长度、膜丝数量、膜丝内径、膜丝壁厚、膜丝孔隙率和膜丝微孔孔径对船舶烟气脱碳效果的影响.实验表明:当膜丝填充率为60％、膜丝长度为700 mm、膜丝数量为700根、膜丝内径为0.52 mm、膜丝壁厚为0.25 mm、膜丝孔隙率为55％、微孔孔径为0.10 μm时,船舶烟气中CO2去除率最高,可以达到83.38％.并得出结论:膜丝内径、膜丝壁厚与脱碳效率成反比,膜丝填充率、膜丝长度、膜丝数量、膜丝孔隙率和膜丝微孔孔径与脱碳效率成正比.
Abstract
To achieve carbon dioxide reduction in the shipping industry,this paper explored the effects of factors such as membrane filaments filling rate,length of membrane filaments,number of membrane filaments,inner diameter of membrane filaments,thickness of membrane filaments,po-rosity of the membrane filaments and membrane filaments microporous aperture on the effect of de-carbonization of the flue gas of ships.The experiments showed that:when the membrane filaments filling rate was 60％,the length of the membrane filaments was 700 mm,the number of membrane filaments was 700,the inner diameter of the membrane filaments was 0.52 mm,the thickness of the membrane filaments was 0.25 mm,the porosity of the membrane filaments was 55％and the diameter of the micropore size was 0.10 μm,the highest removal rate of carbon dioxide in ship smoke could reach 83.38％.And came to a conclusion:the inner diameter and wall thickness of the membrane filaments were inversely proportional to the decarburization efficiency;membrane filaments filling ratio,filaments length,number of filaments,filaments porosity and filaments mi-croporous aperture were positively related to decarburization efficiency for the application of polytetrafluoroethylene hollow fiber membrane in the decarbonization of the flue gas of the ship.
