Detachable hollow fiber membrane module and assembling method thereof

Abstract

The invention relates to a detachable hollow fiber membrane module. The detachable hollow fiber membrane module comprises a hollow fiber membrane fiber and a membrane shell used for mounting the membrane fiber as well as two end covers, wherein a water producing hole is formed in the membrane shell; one needle is inserted into each of the two ends of the membrane fiber, and one clamping ring is arranged at a position corresponding to the needles outside the membrane fiber; the membrane fiber is put into the membrane shell, and the two ends of the membrane fiber and the clamping ring are exposed outside the membrane shell; the two end covers are respectively used for being connected with the two ends of the membrane shell, and one inner hole is formed in the middle of one end of each end cover; and when the end covers are connected with the end part of the membrane shell, the hole wall of the inner hole of each end cover compresses the clamping ring to hoop the membrane fiber and the needles, and the outer ends of the needless pass through the end covers. By adopting the detachable hollow fiber membrane module structure provided by the invention, epoxy resin adhesive sealing does not need to be adopted, and the membrane shell, the end covers and the like are recyclable, so that efficiency is improved, and material waste is reduced.

Description

technical field [0001] The invention belongs to a hollow fiber membrane module. More specifically, the present invention relates to a detachable hollow fiber membrane module structure. Background technique [0002] Hollow fiber membrane (hollow fiber membrane) looks like a fiber. The outer diameter of the hollow fiber is 0.4-2.0mm, and the inner diameter is 0.3-1.4mm. The wall of the hollow fiber tube is covered with micropores. The types of hollow fiber membranes include mixed cellulose ester microporous membranes, nitrocellulose membranes, polyvinylidene fluoride membranes, cellulose acetate membranes, regenerated cellulose membranes, polyamide membranes, and polytetrafluoroethylene membranes. and polyvinyl chloride membranes. Hollow fiber membranes are often used for water treatment, and are used in the fields of pharmaceutical, brewing, catering, chemical industry, municipal sewage reuse, hospital, residential sewage reuse, papermaking and other production and domesti...

AI Technical Summary

Problems solved by technology

However, since the hollow fiber membrane is a polymer material, it does not have rigid characteristics, so it cannot be sealed by rigid thread, hoop and other connection methods.

However, in the process of encapsulating the film wire with epoxy resin glue, it takes several days for the epoxy resin to dry completely, which consumes man-hours

When the membrane is fouled or broken and cannot be used, the entire membrane module including the membrane shell, interface, etc. has to be scrapped.

The membrane shell and interface are reusable engineering materials, scrapping means waste of these materials and may cause environmental pollution
