It is common comprising in more ultrafiltration membrane parallel connection water purification systems, the parallel connection of ultrafiltration membrane is positive rinse when, washing water quantity meeting
One point to be several, i.e. the water flow that every film rinses is divided equally, backwash rate decline, be will lead to ultrafiltration membrane flushing and is not enough, influences
Ultrafiltration membrane flux cleans recovery rate, to achieve the effect that needs, will increase washing time, the dosage for increasing flushing water.
The utility model point of the utility model is: utilizing technological means, realizes that the ultrafiltration system of water processed in parallel can connect
It rinses, increases backwash rate, save washing time and rinse water.
The technical effect that the utility model reaches: in the ultrafiltration system of water processed in parallel, increase backwash rate, save and rinse
Time and rinse water.
In the common water purification system comprising more ultrafiltration membrane parallel connections, ultrafiltration membrane it is positive rinse all be film in parallel simultaneously
Punching, in this case, washing water quantity can one point to be several, i.e. the water flow that every film rinses is divided equally, and backwash rate decline will lead to
Ultrafiltration membrane flushing is not enough, and influences ultrafiltration membrane flux cleaning recovery rate, therefore this backwashing manner is not optimal.
The utility model operates normally two ultrafiltration membrane parallel connections by technological means, when rinsing by two ultrafiltration membrane strings
Connection gets up, and allows all flushing water energys followed by two ultrafiltration membranes, increases the backwash rate of every film, improves ultrafiltration membrane flux
Recovery rate is cleaned, the flow chart of the program is shown in Fig. 1.Concrete operations mode is, when ultrafiltration membrane operates normally, the first on-off control valve
51 is in the open state, and the second on-off control valve 52, third on-off control valve 53 are in closed state；Ultrafiltration film cascade rinses
When, the first on-off control valve 51 is in close state, and the second on-off control valve 52, third on-off control valve 53 are opened, and is rushed in this way
Wash water is first all introduced into the second filter element 22, is fully entered again in the first filter element 21 later, realizes two ultrafiltration
The purpose that film cascade rinses.
But when ultrafiltration membrane in parallel is more than two, and using the flushing of same method, three ultrafiltration membrane parallel-connection flow figures
See Fig. 2, when ultrafiltration membrane operates normally, two the first on-off control valves 51 are in the open state, the 4th on-off control valve 54, third
On-off control valve 53, the second on-off control valve 52 are in close state；When ultrafiltration film cascade rinses, two the first on-off control valves
51 are in closed state, and the 4th on-off control valve 54, third on-off control valve 53, the second on-off control valve 52 are opened, ultrafiltration
Film can connect flushing.
When more ultrafiltration membrane parallel connections, and using the flushing of same process.
In a specific embodiment, ultrafiltration membrane always rinses in a fixed order, if to realize, first rushes ultrafiltration
Film one, backlash ultrafiltration membrane two and first rush ultrafiltration membrane two, backlash ultrafiltration membrane one can be alternately.Then need the process using Fig. 3.
Concrete operations mode is that when ultrafiltration membrane operates normally, the first on-off control valve 51, the 8th on-off control valve 58 are in
Opening state, the 9th on-off control valve 59, the 6th on-off control valve 56, third on-off control valve 53, the 5th on-off control valve 55,
7th on-off control valve 57, the second on-off control valve 52 are closed；Ultrafiltration film cascade rinses, and flush sequence is first to rinse the first filter house
When part 21, the second filter element 22 of backlash, the first on-off control valve 51, the 6th on-off control valve 56, the 5th on-off control valve 55,
7th on-off control valve 57 is in the open state, the 9th on-off control valve 59, third on-off control valve 53, the 8th on-off control valve
58, the second on-off control valve 52 is in close state, and such flushing water is introduced into the first filter element 21, enters back into the second mistake
It filters in component 22；Flush sequence is the 9th on-off control valve when first rinsing the second filter element 22, the first filter element 21 of backlash
59, third on-off control valve 53, the 8th on-off control valve 58, the second on-off control valve 52 are in the open state, the first on-off control
Valve 51 processed, the 6th on-off control valve 56, the 5th on-off control valve 55, the 7th on-off control valve 57 are in close state.Using this
The mode of kind is, it can be achieved that replace the purpose of two ultrafiltration membranes of high flux flushing.
The ultrafiltration membrane parallel connection more than two, and when need to change the sequence of water inlet, and rinsed using this process.
