Sunawa 15
, Hollow fiber IFJ The membrane filtration equipment is backwashed to regenerate its filtration capacity.Specifically, pressurized air is supplied from below the hollow fiber membrane module installed vertically in the line passage to create bubbling. By avoiding the vibration of the hollow fiber membrane filtration device by the door 19 where air bubbles collide with the air bubbles, the turbidity adhering to the surface is removed.During this backwashing operation, the hollow fiber membrane filtration device They are mutually spread out by the rising bubble flow and come into contact with adjacent hollow fiber membrane filtration devices irregularly, but their movement is restricted by the protective cylinder provided on the outer periphery, so that the hollow fiber membrane filters do not get entangled with each other.

Suspended matter also adheres to parts that come in contact with raw water, such as the protective tube and tube plate, and accumulates over time, so it is necessary to periodically remove them. Since this suspended matter is radioactive, if left untreated, the radiation level throughout the filter will rise and the working environment will deteriorate.

問題がある。(Problem to be Solved by the Invention) However, in the conventional breakthrough device, the protective tube installed vertically on the lower surface of the tube plate has its upper end firmly fixed to the tube plate by welding or the like. However, during the manufacturing process of the filtration device, disassembly was difficult. In addition, since a large number of protection tubes are arranged close to each other on the bottom surface of the tube plate, the distance between adjacent protection tubes is very poor, making it extremely difficult to work. It was difficult to reliably clean the surface.Therefore, the inner surface of the filter container body was cleaned during periodic overhaul and inspection.
Furthermore, even after removing the worn hollow fiber hood module from the protective tube and discarding it, and loading a new hollow fiber membrane module, the ability to release deposits remaining on the outer surface of the protective tube causes
There is a problem in that the radiation 'am' increases when the equipment is inactive for two hours, and contamination progresses.

た。For quick replacement work, first take out the used hollow fiber membrane module from the tube sheet and discard it, then take out the new hollow fiber membrane module from the transfer container, and remove the 1.410N1 of the tube sheet.
It consists of the process of inserting the In this case, a sealing mechanism is provided because the gap between the opening of the tube plate and the focusing block of the hollow fiber membrane module that fits into the opening needs to be kept liquid-tight while filtration pressure is applied. , the inner diameter of the frontage of the tube sheet and the outer diameter of the focusing block of the hollow fiber IIQ module form a tight fitting structure. Therefore, it is often difficult to attach and detach the two through the seal gate structure in a site where the working environment is poor. In addition, the work of removing the new hollow fiber membrane membrane from the transfer container, transferring it to the narrow opening of the tube plate, and then inserting it is carried out while preventing damage to the fragile hollow fiber membrane filtration device. It was extremely tedious work, and had the disadvantage of requiring advanced techniques and long working hours.

The protection gap 6 transferred to the site as a tube 111 container is fitted into the 17i10 portion of the tube sheet 4 as it is. After fitting, remove the closing +t [12, 13, screw the Mogicor retaining ring 9 onto the head of the M retention cylinder 6, fix the hollow fiber membrane module 8, and further place the retaining plate 10 on the tube plate 4. Tighten the fixing bolt 11 and fix the whole thing! , 1 constant. On the other hand, the protective cylinder 6 containing the used hollow fiber membrane modules 8 is pumped out from the tube plate 4, washed, and returned to the factory for reuse. In addition, the used hollow fiber rise Joule 8 is extracted from the protective space 6 and a! To be easted.

短縮される。In this way, the installation of the new hollow membrane module 8 is completed by fitting the protective tube 6 and the tube plate 4, which are used as transfer containers, in step 1). This replacement work is greatly simplified compared to the conventional replacement work in which the hollow fiber membrane filtration device, which is fragile, is attached to the tube plate in one place at sites with poor working conditions such as scaffolding and atmosphere. and the working time is significantly reduced.

空糸膜モジュールを損傷から効果的に保護する。As described above, according to the hollow fiber membrane filtration device of the present invention,
The protective tube that removably accommodates the hollow fiber membrane module is detachably attached to the tube plate, so the outer surface can be cleaned by removing the protective tube. Furthermore, since the radioactive suspended matter adhering to the inner surface of the attenuation container can be easily removed, the radiation exposure of the filtration device body can be reduced. Further, since the protection tube can also be used as a container for transporting the hollow fiber membrane module, the protection tube effectively protects the hollow fiber membrane module contained therein from damage even if J3 is in the middle of transfer or replacement work.

管理に大きな効用を発揮する。Furthermore, the hollow fiber membrane module can be replaced and the protector can be installed at the same time by simply fitting and fixing the protector, which accommodates the hollow fiber membrane module, onto the tube plate at the field site in advance at the factory. Therefore, the work process at the site where the work environment is poor is simplified, the work time is significantly shortened, and it is highly effective in the maintenance and management of line communication systems.
