| Abstract: | This paper puts forward the new technology of making asymmetric ceramic composite film tube. First, materials including SiC and Al2O3 are fired into the porous ceramic substrate after static pressure molding. The asymmetric ceramic tube membrane is made by high temperature sintering after reaching the required film thickness by leaching pulp and drying for many times. The high temperature flue gas composite membrane filter can be applied to remove dust and gas in metallurgical processing. SEM and EDS are used to characterize the porous ceramics matrix and microporous composite membrane. The results show that they have good pore structure and physical properties. A set of cold model test devices for measuring dust filtration efficiency of asymmetric ceramic composite membrane is designed and reasonable parameters are determined through experiments. |
