Rotating cross-flow flat ceramic membrane separation turntable

The invention relates to a rotating cross-flow flat ceramic membrane separation turntable, which comprises a hollow central shaft, a support component fixedly arranged on the hollow central shaft, a plurality of flat ceramic membrane components supported by the support component and a driving mechanism for driving the hollow central shaft to rotate, wherein each flat ceramic membrane component comprises a hollow cavity type flat ceramic membrane; each hollow cavity type flat ceramic membrane comprises two separated surface membrane layers; a plurality of liquid collection accommodation cavities and liquid outlets are formed around the hollow cavity type flat ceramic membranes; a plurality of cavities are formed in the hollow cavity type flat ceramic membranes. According to the turntable, a flat ceramic membrane filtering technology is adopted, the characteristics of strong strength, convenience in high-pressure back washing and the like of the ceramic membranes are fully utilized, and the application fields of a rotating cross-flow membrane separation technology are well extended.
