Hollow fiber membrane assembly pouring device and method thereof

Abstract

The invention discloses a hollow fiber membrane assembly pouring device and a method thereof. The hollow fiber membrane assembly pouring device is composed of a flexible pad, a membrane assembly shell, a connecting piece, a pouring mould and an adhesive stirring tank, wherein hollow fiber membrane filaments are uniformly arranged by additionally arranging the flexible pad which is uniformly provided with holes, the roots of the membrane filaments are protected, an adhesive is prevented from entering the membrane filaments by blocking the two ends of the membrane filaments through a sealant, and an ultrasound defoaming device is additionally arranged in the adhesive stirring tank so that the defoaming efficiency can be improved, the components of the adhesive are also uniformly dispersed, and the mechanical strength of a membrane assembly is improved. The hollow fiber membrane assembly pouring device and the method thereof provided by the invention have the advantages that the pouring of a membrane assembly end socket is uniform, bubbles are not generated, glue leaking and cracking phenomena are avoided, meanwhile, the roots of the membrane filaments are effectively protected, a filament breaking phenomenon is prevented, the pouring quality of the hollow fiber membrane assembly is improved, the service life of the membrane assembly is prolonged, the equipment investment is small, the operation is convenient and rapid, and the hollow fiber membrane assembly pouring device can realize large-scale industrial application easily.

Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a hollow fiber membrane module pouring device and a method thereof. Background technique [0002] Membrane separation technology is a high-tech widely used in liquid or gas separation, purification or concentration. Due to its large specific surface area, high packing density, simple process, no support layer, and low production cost, hollow fiber membranes have become an important branch of membrane separation technology and are widely used in chemical, environmental protection, and pharmaceutical fields. The hollow fiber membrane usually uses the membrane module as the permeation unit, and the membrane module is composed of a large number of hollow fiber membrane filaments solidified in the membrane shell through an adhesive to form a relatively closed separation environment. The pouring quality of the membrane module has a great influence on the performance and ef...

Problems solved by technology

[0006] However, the above methods only change the shape of the mold and the way of glue feeding or impregnate the root of the membrane with a protective layer, without considering the influence of the impregnating liquid on the filter layer on the surface of the fiber membrane. The influence of water quality, the uniform distribution of membrane filaments and the degassing of adhesives, etc.

At present, the degassing of adhesives is mostly carried out by vacuuming, but this method takes a long time, has low efficiency, and has high requirements on the sealing and material of the equipment, and the degassing effect is not ideal.
