| titleOfInvention | Multi-channel tubular ceramic membrane element |
| abstract | The invention discloses a multi-channel tubular ceramic membrane element which comprises a porous support layer and a top-layer membrane layer coating the surface of the porous support body, wherein the top-layer membrane layer is prepared by adopting a method comprising the following steps: (1) preparing a powder body I with a diameter of about 200-300nm; (2) preparing a powder body II with a particle size of 1-2 micrometers; and (3) mixing the powder body I and the powder body II, adding a dispersing agent in the mixed powder body, ball-grinding and mixing to obtain a uniform and stable top-layer membrane suspension slurry, and sintering at a temperature of 1200-1300 DEG C. According to the multi-channel tubular ceramic membrane element, the property of a coating slurry can not be influenced, the continuity of the surface of the membrane can not be damaged and the permeability is not reduced; the multi-channel tubular ceramic membrane element has a function of only forming mutually-discontinuous bulges, and a turbulent flow caused by the bulges ensures that the permeation flow around the turbulent flow is remarkably increased and kept not being attenuated. |
