Membrane separation device and method

Abstract

The invention provides a membrane separation device which comprises a bearing table, a separation mechanism and a collection mechanism. The bearing table comprises a bearing surface, wherein the bearing surface is used for adsorbing a substrate of a diaphragm, and the collecting mechanism comprises a collecting surface; the bearing surface and the collecting surface are arranged on the two sides of the separating mechanism correspondingly. The bearing surface is opposite to the separation mechanism; the collecting surface is opposite to the separating mechanism, the separating mechanism comprises a separating roller, the separating roller can rotate around the axis of the separating roller and can move relative to the bearing table at the same time, a plurality of first outer air holes areformed in the outer surface of the separating roller, and the multiple first outer air holes can suck air or spray air respectively. The invention further provides a membrane separation method. According to the membrane separation device, the functional layer of the body of the membrane can be prevented from being damaged or polluted in the separation process.

Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a membrane separation device and a membrane separation method performed by the membrane separation device. Background technique [0002] At present, related diaphragm separation technologies include mechanical stripping, laser stripping, and wet etching stripping. In the wet etching stripping technology, the main body of the diaphragm needs to be separated from the substrate of the diaphragm after the wet stripping. In the prior art, there is a problem that the functional layer of the main body of the diaphragm is damaged or polluted during the separation process of the main body of the diaphragm and the substrate of the diaphragm. [0003] Therefore, how to design a membrane separation mechanism to avoid damage or contamination of the functional layer of the membrane body during the separation process of the membrane body and the membrane substrate has become an urg...
