Description
Technical Field
The invention relates to a method and a device for uniformly distributing and arranging membrane filaments of a hollow fiber membrane component, in particular to a method and a device for uniformly distributing and arranging membrane filaments by using adhesive tapes, and belongs to the technical field of preparation of hollow fiber membrane components.
Background
Membrane modules are the core of membrane technology applications. In particular to a hollow fiber membrane component, the preparation technology is relatively simple, no support body is needed, the filling density is high, the efficiency is high, and the like, and the hollow fiber membrane component is widely applied to various fields of membrane separation. Most of ideal hollow fiber membrane components are membrane filaments which are arranged in parallel along the axial direction of the component, but the problem of uneven arrangement and distribution of the hollow fiber membrane filaments always exists in the process of actually manufacturing the membrane components, so that the distribution of the permeability coefficient of the membrane filaments is uneven, the three-dimensional unevenness of flux distribution is caused, the energy consumption of equipment is increased, and the efficiency of the component is reduced.
Particularly, in the hollow fiber membrane module for membrane distillation, the uneven arrangement and distribution of membrane filaments in the membrane module can cause uneven distribution of shell-side fluid, and the channeling effect, which is an undesirable behavior such as channeling, dead zones and the like, exists. The effect greatly reduces the mass transfer and heat transfer efficiency of the membrane component.
At present, most of adopted hollow fiber membrane component manufacturing methods have the game effect (sacrificing the uniform distribution of membrane filaments in the component, improving the production efficiency, or reducing the production efficiency and optimizing the distribution of the membrane filaments in the component). The existing methods for manufacturing hollow fiber membrane modules are method 1 and method 2.
The comparative example is a self-made PVDF hollow fiber membrane filament with self-support, the membrane filament is subjected to end capping treatment (preventing epoxy resin glue from entering from a membrane filament port) before casting, all the end capped membrane filaments are randomly placed in a membrane shell of a membrane component at one time, the epoxy resin glue is used as a binder, the hollow fiber membrane filament and an outer structural member are subjected to centrifugal or standing casting bonding together, the hollow fiber membrane filament and the outer structural member are cut after complete curing is required, the adhesion among the membrane filaments in the membrane component is serious, the distance distribution among the membrane filaments is extremely uneven, the membrane filaments in the component are in a loose state, the membrane filaments can swing in the fluid flowing process to cause damage to the root of the membrane filaments, and the filtering performance and the service life of the membrane component are influenced.
The comparative example is a self-made self-supporting PVDF hollow fiber membrane filament, the membrane filament is subjected to end sealing treatment before casting, all the end-sealed membrane filaments are divided into a plurality of bundles, then each bundle is sequentially inserted into a mould (petal) of the membrane component, epoxy resin is used as a binder, the hollow fiber membrane filament and an outer structural member are centrifuged or statically cast and bonded together, and cutting is carried out after complete curing is carried out to obtain the membrane component, wherein the distribution among the fiber filaments of each bundle is better, but serious adhesion exists among the membrane filaments of each bundle, and the filtering performance of the membrane component is seriously influenced. The number of petals in the mould is not too large, otherwise, the manufacturing process of the membrane component is more complicated, and the efficiency is reduced; petals in the die are not too few, otherwise, the number of membrane filaments in each bundle is more, and the phenomenon of adhesion among the membrane filaments is more serious.
