Time, the dense water outlet 52 on this big flow circulation variable frequency pump 50 is connected to high pressure by outlet conduit 521
The outlet of variable frequency pump 30 such that it is able to realize via this high-pressure frequency-conversion pump 30, this dense water is back to film group
On part 40, the most again it is back to big flow circulation variable frequency pump 50 via this membrane module 40, by that analogy.
Specifically, this outlet conduit 521 is provided with control valve (not shown), in order to control dense water at this outlet pipe
Current intelligence in road 521.And preferably, for the ease of controlling dense water in this outlet conduit 521
Flow velocity, this outlet conduit 521 is additionally provided with second gauge (not shown).
Specifically, when operating, after dense water is carried out supercharging via this booster pump 10, through ensuring public security
Filter 20 filters, after then flowing to this at least one membrane module 40 via this high-pressure frequency-conversion pump 30, now,
The dense water of a part is discharged respectively via dense water collection pipe and pure water collection pipe, and the dense water of another part
After being back to high-pressure frequency-conversion pump 30 by this concentrate recirculation pipe 511 via this big flow circulation variable frequency pump 50,
Again flow to this at least one membrane module 40, circulate with this.Due to this dense water again and again circulating reflux, because of
This, its response rate and the pollutant deposition on membrane module surface can be reduced.
The circulating anti-soil of big flow that this utility model embodiment provides blocks up membrane separation device 100, big by increasing
Flow circulation variable frequency pump 50, is connected to concentrate recirculation mouth 51 pipeline of big flow circulation variable frequency pump 50 at least
The outlet of one membrane module 40, is then connected to going out of high-pressure frequency-conversion pump 30 by dense water outlet 52 pipeline
The mouth of a river.After dense water flows to membrane module 40 via this high-pressure frequency-conversion pump 30, it is possible to by this concentrate recirculation
Mouth 51 carries out being back to the outlet of high-pressure frequency-conversion pump 30, the most again flows to this membrane module 40.Utilize
The backflow of big flow circulation variable frequency pump 50 is arranged, it is possible to increase while the response rate of dense water, additionally it is possible to film
The surface of assembly carries out washing away and cleaning, and prevents membrane module surface to be contaminated thing blocking, and then reduces film
Assembly carries out Chemical cleaning, cost-effective and extend service life of membrane module.
