Abstract
A novel hollow fiber membrane module having aeration function includes a housing (1), membrane fibers (2), and a central water collection pipe (3), wherein the membrane fibers (2) are installed via an epoxy tube plate sealing end (4) at one end, and an epoxy plug-up end (5) at the other end, a nozzle (6) is arranged on the epoxy plug-up end (5), the central water collection pipe (3) is arranged between two bundles of membrane fibers (2), a raw material inlet (9) is also arranged on the housing (1). The novel hollow fiber membrane module is characterized in that: the central water collection pipe (3) extends out of the two ends of the housing (1) to form an air inlet nozzle (7) and a water outlet (8). The novel hollow fiber membrane module having aeration function provided by the invention has the advantages of simple installation, convenient adjustment, and durability. The nozzle is located at the same side with the inlet of feed liquid, to realize convenient installation and use. By the adding of air, the impact strength of the feed liquid to the membrane surface is increased, to improve the flushing effect, and facilitate the recovery of the membrane flux. At the same time, the flow of cleaning can be properly reduced, and the cleaning effect for the membrane can be reached.
Description
Technical field
The present invention relates to a kind of polysulfone hollow fiber ultrafiltration membrane system, in the process that film is cleaned, add simultaneously air to strengthen the membrane washing effect, belong to the sewage treating material field.
Background technology
At present, hollow fiber ultrafiltration membrane is main mainly with pillar, namely the two ends of multi beam hollow fibre filament is poured into respectively in two terminations with epoxy, and then two ends get final product with public attention connection.There is following shortcoming in this form: film silk root is easily thrust by mass-flow when backwash; Simultaneously, owing to backwash intensity is difficult for strengthening so that the membrane washing poor effect is very easy to cause the dirt of film silk stifled, pollutant can flow to the film silk and block the minimizing that causes the membrane filtration area when serious, thus so that the disposal ability of membrane module reduction.
Summary of the invention
The present invention provide a kind of have install simply, easy to adjust, durable in use, strengthen the intensity of cleaning hollow fiber film thread, the filter efficiency of membrane module is promoted, prevent the Novel hollow cellulosic ultrafiltration membrane module that the film runner is blocked up by dirt.
The present invention is by the following technical solutions:
A kind of Novel hollow fiber membrane module with inflating function, comprise that shell body, film silk, center collector pipe, described film silk epoxy tube sheet end-blocking and the epoxy of the other end by end shut end and install, shut end at epoxy and be provided with valve, described center collector pipe is arranged between the two bundle film silks, also be provided with the feed(raw material)inlet on the described housing, the two ends that described center collector pipe stretches out housing form suction nozzle and delivery port.
The invention has the advantages that to have and install simply, easy to adjust, durable in use, valve and liquor inlet be in the same side, be installed on very easy to use, by the adding of air, so that feed liquid has improved developing result to the scouring intensity increase on film surface, helpful to the flux recovery of film; Simultaneously, can suitably reduce the flow of cleaning, just can reach the membrane washing effect.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, a kind of Novel hollow fiber membrane module with inflating function, comprise that shell body 1, film silk 2, center collector pipe 3, film silk 2 epoxy tube sheet end-blocking 4 and the epoxy of the other end by end shut end 5 and install, shut end 5 at epoxy and be provided with valve 6, described center collector pipe 3 is arranged between the two bundle film silks 2, also be provided with feed(raw material)inlet 9 on the housing 1, center collector pipe 3 stretches out the two ends of housing 1, forms suction nozzle 7 and delivery port 8.
Manufacture method according to hollow fiber film assembly is produced, just install ventilation nozzle 7 additional in the import department of feed liquid, when rinsing membrane module, pass into simultaneously like this compressed air, make air flow through the face of film silk 2 with feed liquid, utilize the souring of microbubble that the dirt on film surface is removed, the method is particularly useful for external pressure type hollow fiber membrane component.
Claims (1)
1. Novel hollow fiber membrane module with inflating function, comprise shell body (1), film silk (2), center collector pipe (3), described film silk (2) is by the epoxy tube sheet end-blocking (4) of end, shutting end (5) with the epoxy of the other end installs, shut end (5) at epoxy and be provided with valve (6), described center collector pipe (3) is arranged between the two bundle film silks (2), also be provided with feed(raw material)inlet (9) on the described housing (1), it is characterized in that: described center collector pipe (3) stretches out the two ends of housing (1), forms suction nozzle (7) and delivery port (8).
