Problems solved by technology

In addition to the membrane flux related to the water quality of the membrane feed water and the performance of the membrane base material itself, another important factor affecting the membrane flux is the diversion net. Different structural forms and sizes of the diversion net will affect the membrane flux. If the selection of the diversion net is not suitable, the water production will be blocked and back pressure will be generated, which will cause damage to the diaphragm

Abstract

The invention relates to the technical field of flow guide net detection, in particular to a device for testing the performance of a membrane module flow guide net. The device comprises a supporting frame and a pressure-bearing testing mechanism. The device is designed aiming at the properties such as the net wire diameter, the aperture ratio, the weaving mode, the aperture and the like of a membrane flow guide net prepared by a membrane method water treatment; different flow guide nets are tested; water permeability of different flow guide nets, radial deformation of verification wires and strength of the flow guide nets can be screened out quickly and effectively, proper flow guide nets are selected for different working conditions, pressures (especially under high pressure and special working conditions) and membrane types, products meet customer requirements, the development period is shortened, and the development and operation cost is reduced. The device is novel in structure, easy to operate and efficient and rapid in testing process.

Description

technical field [0001] The invention relates to the technical field of diversion net detection, in particular to a performance testing device and a testing method for a diversion net of a membrane module. Background technique [0002] In recent years, membrane materials, as an emerging material, have been more and more widely used in environmental protection water treatment and clean production processes. In the application of membrane technology, the membrane flux (that is, the water flux per unit membrane area per unit time) is an important factor affecting the system investment. In addition to the membrane flux related to the water quality of the membrane feed water and the performance of the membrane base material itself, another important factor affecting the membrane flux is the diversion net. Different structural forms and sizes of the diversion net will affect the membrane flux. If the selection of the diversion net is inappropriate, the water production will be blo...
