Description
Technical field
The utility model relates to a kind of purging system, especially relates to a kind of milipore filter purging system.
Background technology
Because the function of milipore filter is to remove the contained impurity of former water, the various impurity that the film surface can be retained down covers, and fenestra can be stopped up by more tiny impurity, thereby reduces the strainability of milipore filter.The quality of former water pretreatment can only determine the speed that ultrafiltration membrane elements is stained, and can't fundamentally solve the dirty stifled problem of ultrafiltration membrane elements, is absolute so the dirt of ultrafiltration membrane elements is blocked up, and therefore general ultrafiltration system is equipped with physical cleaning and Chemical cleaning.Physical cleaning comprises waterpower backwash, waterpower square impact and air bump rinse operation; Chemical cleaning comprises that maintainability cleans and restorative cleaning.Chinese patent discloses a kind of ultrafiltration device purifier (Granted publication number: CN2848344), the outlet of its transfer groove uses the pipeline with valve and pump to be connected with the import of ultrafiltration apparatus, and pump and valve are followed successively by the first valve, pump, the second valve, the 3rd valve by the order that pure water flows to; The outlet of ultrafiltration apparatus uses the pipeline with the first valve to be connected with transfer groove; Connect with pipeline and the 4th a valve place pipeline with the 5th valve between the second valve and the 3rd valve, contact is in the outlet direction of the 4th valve.But this purging system can't clean acid solution, the alkali lye that remains in the female pipe of milipore filter cleaning, therefore can cause wastage of material, and more unholiness in the pipeline.
The utility model content
The utility model provides a kind of milipore filter purging system, it mainly is to solve the existing purging system of prior art can't acid solution, the alkali lye that remain in the female pipe of milipore filter cleaning be cleaned, therefore can cause wastage of material, and more unholiness etc. technical problem in the pipeline.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of milipore filter purging system of the present utility model, comprise ultrafiltration apparatus, described ultrafiltration apparatus is connected with ultrafiltration by pipeline and cleans cartridge filter, ultrafiltration is cleaned cartridge filter and is connected respectively ultrafiltration alkali flushing water pump, ultrafiltration acid flushing water pump, ultrafiltration alkali flushing water pump, ultrafiltration acid flushing water pump connects respectively ultrafiltration alkali and cleans water tank, water tank is cleaned in ultrafiltration acid, ultrafiltration alkali flushing water pump, also be connected with the hyperfiltration rinsing water case by pipeline between the ultrafiltration acid flushing water pump, ultrafiltration alkali cleans water tank, water tank is cleaned in ultrafiltration acid, the exit of hyperfiltration rinsing water case and ultrafiltration alkali clean water tank, water tank is cleaned in ultrafiltration acid, the hyperfiltration rinsing water case interconnects pipeline and is provided with automatic valve.
When recovering cleaning process owing to the ultrafiltration apparatus film, pickling, alkali cleaning one after the other are carried out, and such as untimely flushing, milipore filter cleans female pipe meeting residual fraction acid solution, alkali lye, and a part of liquid will certainly neutralize.The utility model increases by two milipore filters and cleans water tank, after pickling, alkali cleaning, use clear water flushing ultrafiltration membrane elements, the acid-base solution flushing that pipe interior is residual enters ultrafiltration membrane elements, stop the neutralization that milipore filter cleans female pipe meeting residual fraction acid solution, alkali lye, improve the utilization rate of acid-base solution; And cleaning water tank, ultrafiltration acid at ultrafiltration alkali cleans the exit of water tank, hyperfiltration rinsing water case and ultrafiltration alkali and cleans that water tank, ultrafiltration acid clean water tank, the hyperfiltration rinsing water case interconnects pipeline and is provided with automatic valve, can automatically switch by programme-control automatic valve, flushing water pump after ultrafiltration pickling, the alkali cleaning and open immediately ultrafiltration and clean water tank and ultrafiltration membrane elements, milipore filter are cleaned female pipe carry out hydrodynamic cleaning, can effectively save the ultrafiltration apparatus film and recover scavenging period, simple and reasonable for structure.
