Abstract
The invention discloses an ultrafiltration membrane cleaning machine with recyclable cleaning fluid. The ultrafiltration membrane cleaning machine comprises a storage container for containing the cleaning fluid. The cleaning fluid goes through a first filter, a booster pump and a disk type filter in sequence and then enters an ultrafiltration component; effluent fluid of the ultrafiltration component returns to the storage container after filtration by a second filter; and both the filter mediums of the first filter and the second filter are gravel particle filter material. Clotted protein and colloid substance cleaned away from an ultrafiltration membrane are filtered out of the ultrafiltration membrane cleaning fluid by the filter material of the first filter and the second filter, so that the cleaning fluid is always kept clean as before and the purpose of repeated use is achieved.
Description
Technical field
The present invention relates to a kind of milipore filter cleaning machine, be specifically related to be applicable to the film cleaning machine of tubular membrane, rolled film, hollow-fibre membrane.
Background technology
Milipore filter (like tubular membrane, rolled film, hollow-fibre membrane) is widely used in the separation, degerming, removal of impurities in fields such as medicine, food, fine chemistry industry etc.This kind film is because filter material is special and accurate, and manufacturing process is complicated, causes price comparison expensive; Therefore how to clean and can satisfy technological requirement; Improve the service life of this film to greatest extent, energy-saving and emission-reduction are problems that numerous use milipore filter producer is being explored always.
The producer of existing domestic use milipore filter, employing be the film system back on-line cleaning technology that stops production, promptly former machine stops charging earlier, changes cleaning fluid and directly cleans.Because this equipment does not have special cleaning fluid to filter and retracting device; The former stagnant materials of depositing such as having the interior coagulated protein of film, colloid class that stagnates under filtering is pointedly cleaned; A large amount of cleaning fluids can not be recycled, can only directly discharge, increased wastewater treatment expense and environmental pollution.
In addition; In the former on-line cleaning technology; Media flow in the membrane module is inhomogeneous, and cleaning fluid can only inertia according to former material charging path flows, can not comprehensively clean milipore filter; Cause the film heart to be detained the coagulated protein and the colloid class material of some, the milipore filter after the cleaning does not reach the original performance of this film, has shortened service life of this film greatly.
