Embodiment Construction

[0021] Combine below Figure 1-2 The present invention will be further described with specific embodiments.

[0022] A sheet curtain membrane encapsulation and leak plugging process such as figure 1 , 2 shown, including the following steps:

[0023] 1) Pre-encapsulation: 180 hollow fiber membrane filaments 8 with a specification of 1.0m in length, 1.1mm in outer diameter, and 0.55mm in inner diameter are formed into membrane filament bundles, and 10 bundles are taken, and the upper end is used for conventional packaging and fixing. Cut the lower ends of the membrane filaments 8 evenly, plug the membrane filament holes with a conventional plugging process, clamp them with a clamp, hang the fixed ends of the 8 bundles of membrane filaments vertically on the packaging table, insert the lower ends vertically into the open packaging box 1, and pour the first The glue layer 2 is liquid epoxy resin with a height of 3 cm and a hardness of shoreD40, so that the outside of the lower ...

Abstract

The invention relates to the technical field of membrane separation and particularly relates to and discloses a flaky curtain type membrane packaging and leaking stoppage process. The flaky curtain type membrane packaging and leaking stoppage process includes the following steps of pre-packaging, wherein the lower ends of membrane filaments are cut to be flat, holes are blocked, the membrane filaments are vertically arranged in an open packaging box, first glue layer liquid is poured, and standing for curing is carried out; secondary packaging, wherein the membrane filament holes in the end face of the packaging box are cut open, the packaging box is inserted into a step inside a water collecting pipe and is sealed and bound, second glue layer liquid is poured on a first glue layer, and standing for curing is carried out; forming of a protective layer, wherein third glue layer liquid continues to be poured, and standing for curing is carried out; leaking stoppage, wherein gas leakage detection is carried out, cutting off is carried out at a leaking point, pyrocondensation materials are sleeved with the two ends, heating is carried out, leakage detection is carried out again till no abnormality exists, and a finished flaky curtain type membrane is prepared. According to the flaky curtain type membrane packaging and leaking stoppage process, through three times of glue layer pouring, packaging efficiency is guaranteed, the problem of leaking points caused by root filament breakage is effectively solved, packaging quality is guaranteed, packaging is attractive and free of flaws and knotting, cost is low, efficiency is high, and the process is suitable for volume production.

Description

technical field [0001] The invention relates to the technical field of membrane separation, in particular to a sheet curtain membrane encapsulation and plugging process. Background technique [0002] In the existing hollow fiber membrane module structure, in order to improve the packaging efficiency, a better method is to pour epoxy resin directly on the membrane module (including multiple or bundles of membrane filaments), and then pour a layer of silica gel on it ( or polyurethane), after standing for a period of time, the membrane silk hole is cut out, the water collecting pipe is bonded, and then the gas leak is detected directly. However, the current one-time pouring epoxy and silica gel production process has poor plugging quality, and still cannot solve the broken wire leakage caused by the root of the hollow fiber membrane when it is aerated and oscillated, and the effect of later rework is not obvious. [0003] For example: the patent "a casting method for polytetr...
