The present invention is a device that is for cleaning a porous hollow fiber membrane by running the porous hollow fiber membrane through a cleaning tank containing a cleaning liquid, thus eliminating residual substances in the porous hollow fiber membrane, wherein the inside of the cleaning tank is provided with a duct structure having a hollow fiber membrane running path at which the porous hollow fiber membrane can be continuously run through from an entrance at one end towards an exit at the other end; the duct structure comprises at least two structures that can separate; the duct structure has a running groove, which is formed to at least one structure of the at least two structures, and a branched duct, which pumps or sucks the cleaning fluid to cause the cleaning fluid to flow through; and the branched duct is a duct that is connected to the running groove. By means of the present invention, it is possible to provide a device that is for cleaning a porous hollow fiber membrane and that is highly efficient, is able to be easily maintained, and can dispose the porous hollow fiber membrane easily and efficiently.
Description
technical field [0001] The invention relates to a cleaning device for a porous hollow fiber membrane. [0002] This application claims priority based on Japanese Patent Application No. 2011-098204 for which it applied in Japan on April 26, 2011, and Japanese Patent Application No. 2011-098205 for which it applied in Japan on April 26, 2011, and uses the content here. Background technique [0003] For the concentration and recovery of useful components in the food industry, medical or electronic industries, or the removal or distillation of unnecessary components, precision filtration membranes, superfiltration membranes or reverse osmosis filtration membranes are often used with acetate cellulose, polypropylene A porous hollow fiber membrane having a hollow porous layer made of nitrile, polysulfone, or fluorine-based resin, for example, produced by wet or dry-wet spinning. [0004] When producing a porous hollow fiber membrane by wet or dry-wet spinning, first, a membrane-f...
