new technology for the preparation of multilayered polymer mixed matrix membranes and membrane and device for distillation

摘要

the invention relates to a process for the manufacture of a mixed matrix membrane layer, which includes the use of a backing layer, a hydrophilic layer on the casting surface of the backing layer, a hydrophobic layer on the casting operation and the hydrophilic layer phenomenon to allow the layers to form a multilayer mixed matrix membrane.the invention also relates to a process for the manufacture of a composite membrane of hollow fiber as matrix, which includes the use of a first solution comprising a hydrophilic polymer.the use of a second solution comprising a hydrophobic polymer and extrusion of the first and second solutions to form a multilayered composite membrane matrix in the form of a hollow fiber. in addition, the invention relates to a membrane module in membrane distillation plate contact using a mixed matrix membrane layer.the membrane includes a module plate to distribute the power entry module process solution in the membrane to divide the entry process solution to permeate in the membrane module, an accelerator complex, multi. the flow out of feed and permeate outlet.
