High-strength hollow fiber membrane module and preparation method thereof

Abstract

The invention relates to a high-strength hollow fiber membrane module and a preparation method thereof. The high-strength hollow fiber membrane module at least comprises an outer membrane cavity and an inner membrane core which is assembled inside the outer membrane cavity, wherein one end part of the inner membrane core is taken as an epoxy resin polystyrene sealing end, and the other end part of the inner membrane core is taken as an epoxy polystyrene resin casting end; two sides of the outer membrane cavity are provided with a left end part gland and a right end part gland respectively; the left end part gland is assembled on one side of the epoxy resin sealing end; an epoxy resin flexible glue protection layer is arranged beside the epoxy resin polystyrene sealing end; an outlet end epoxy resin flexible glue protection layer is cast beside the epoxy resin polystyrene casting end. By adopting the high-strength hollow fiber membrane module, hollow fiber membrane filaments beside the casting end can be effectively prevented from being damaged, and the service life of the hollow fiber membrane module is prolonged; the airtightness of the hollow fiber membrane module, particularly on sealing parts at two ends of the membrane filaments is enhanced, the requirement on separation at a high temperature is met, and the separation efficiency is increased. At the same time, the invention further provides a preparation method of the hollow fiber membrane module.

Description

technical field [0001] The invention relates to the technical field of hollow fiber membranes, in particular to a high-strength hollow fiber membrane module and a preparation method thereof. Background technique [0002] Hollow fiber membrane separation technology is widely used in food, medicine, chemical industry, water treatment and other fields. Studies have shown that the separation efficiency of hollow fiber membranes increases as the temperature increases. However, due to design defects in existing hollow fiber membrane modules, their airtightness and service life are easily affected in high temperature environments. The sealing part is easy to fall off, and there are serious process defects; at the same time, the existing hollow fiber membrane module is easy to cause membrane blockage and membrane damage during the water treatment process, especially when the water treatment contains high concentration of metal pollutants. It accelerates the early scrapping of hollo...

Studies have shown that the separation efficiency of hollow fiber membranes increases as the temperature increases. However, due to design defects in existing hollow fiber membrane modules, their airtightness and service life are easily affected in high temperature environments. The sealing part is easy to fall off, and there are serious process defects; at the same time, the existing hollow fiber membrane module is easy to cause membrane blockage and membrane damage during the water treatment process, especially when the water treatment contains high concentration of metal pollutants. It accelerates the early scrapping of hollow fiber membrane modules; more importantly, due to design defects of the existing hollow fiber membrane modules, after the epoxy resin hard glue is cast on both ends of the existing hollow fiber membrane modules, due to the capillary action of the epoxy resin, the casting The hollow fiber membranes on the side of the end are easily damaged, which greatly reduces the service life of hollow fiber membrane modules based on hollow fiber membranes
