Ultrafiltration membrane cleaning machine

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 [0001] The invention relates to an ultrafiltration membrane cleaning machine, in particular to a membrane cleaning machine suitable for tubular membranes, roll membranes and hollow fiber membranes. Background technique [0002] Ultrafiltration membranes (such as tubular membranes, roll membranes, and hollow fiber membranes) are widely used in separation, sterilization, and impurity removal in the fields of medicine, food, and fine chemicals. Due to the special and precise filter material and the complicated manufacturing process of this kind of membrane, the price is relatively expensive. Therefore, how to clean and meet the process requirements, maximize the service life of the membrane, save energy and reduce emissions, is a constant issue for many ultrafiltration membrane manufacturers. The question being explored. [0003] At present, manufacturers using ultrafiltration membranes in China adopt the online cleaning process after the membrane system is shu...

AI Technical Summary

Problems solved by technology

Since the equipment does not have a special cleaning liquid filtration and recovery device, it cannot filter out the stagnant substances such as coagulated protein and colloid that are originally stagnant in the membrane after cleaning, so that a large amount of cleaning liquid cannot be recycled and can only be used. Direct discharge increases wastewater treatment costs and environmental pollution

[0004] In addition, in the original online cleaning process, the medium in the membrane module flows unevenly, and the cleaning solution can only flow inertially according to the raw material feeding route, and cannot fully clean the ultrafiltration membrane, resulting in a certain amount of coagulated protein and Colloidal substances, the ultrafiltration membrane after cleaning can not reach the original performance of the membrane, which greatly shortens the service life of the membrane
