Raw water is loaded in water tower 110, raw water flows valve 114 and flow by raw water water inlet pipe 112 and by a weighing apparatus
Meter 116 enters device for ultrafiltration membrane 120.After 120 separating and filtering of device for ultrafiltration membrane, membrane module pure water pipe is passed through in the water purification of generation
121 enter with intermediate water purification pipeline 123 in intermediate water tank 130, and the water in intermediate water tank 130 passes through water tank water pipe 132 and flows into storage
In pond 150, the water in tank 150 is sent into user family for users to use by water pipeline 152.
After 120 separating and filtering of device for ultrafiltration membrane, the sewage of generation passes through membrane module sewage pipe 122 and intermediate waste pipe
Road 124 enters cleaning device 140, and sewage drainage pipe 125 is connected on the bottom of the cleaning device 140.Since weighing apparatus flows valve 114
Current stabilization acts on and Water level trend pressure keeps weighing apparatus effect, and the wastewater level in external pipe 141, which will be located to keep at a of Hengshui position, to be carried out
It floats.
When the membrane module of device for ultrafiltration membrane 120 is blocked by dirt, the cleaning device course of work is as follows：
For device for ultrafiltration membrane 120 using after long-time, the pollutant in membrane module is excessive, and film wire hole is blocked, concentration of wastewater
It increases, the reading of flowmeter 116 is decreased obviously at this time, and water yield is reduced.Membrane module sewage pipe 122 and intermediate waste pipeline 124
In pressure increase, the water level in cleaning device 140 is gradually increasing, from when keeping Hengshui position a and rising to from water level line b, water level line b
It is aligned with the top end opening of air water suction generator tube 147；Pressure in 140 top chamber A of cleaning device increases, and forms one
0.5 kilogram or more of baric area.It is risen to due to water level at the top end opening of air water suction generator tube 147, water can enter air water
Suction generator tube 147, and flow downward, This move has broken the balance of sealing space gas and water, and flowing water is mingled with
Air forms air-water mixture.Air-water mixture in air water suction generator tube 147 finally flows into auxiliary water tank 143, auxiliary
Help progress aqueous vapor separation in water tank 143.
Since the balance in top chamber A is destroyed, air drag is reduced, and water level rapidly rises, when water level reaches water
When at bit line c, the hanging of water level line c and internal pipeline 142, water level reach the top of internal pipeline 142, top chamber A
In air under the drive of water, formed air-water mixture, flowed rapidly into auxiliary water tank 143 from internal pipeline 142, auxiliary
Help progress aqueous vapor separation in water tank 143.
Air pressure in top chamber A continuously decreases, and water level continues rapid increase, until the air pressure in top chamber A becomes
Negative pressure stops supplying water to tank 150, assists bucket at this point, the on-off valve on intermediate water tank 130 is controlled by a controller closing
Water in 144 is inhaled into vacuum breaking pipe 145, and the gas in 145 pipeline of vacuum breaking pipe is squeezed into top chamber A, into
The air entered in top chamber A continues as flow is discharged into auxiliary water tank 143.After the air of vacuum breaking pipe 145 is drained,
Siphonage is formed, gravity and it is totally-enclosed under the action of, the gravity of flow can be accelerated to accelerate in about 3-5 seconds time
Degree, under the action of powerful suction force, the dirt in the membrane module of device for ultrafiltration membrane 120 can be quick along water (flow) direction
It goes out, this is along washed journey.It is as follows with along the synchronous backwash process of washed journey：While along washed Cheng Jinhang, intermediate water tank 130
In water pass through intermediate water purification pipeline 123 and membrane module pure water pipe 121, be reverse flowed to membrane module, membrane module reversely rushed
It washes.
The end of flushing process：Water in intermediate water tank 130 because backwash process gradually decreases, water level gradually decrease to it is auxiliary
Help the top surface of bucket 144 parallel, the water in intermediate water tank 130 is separated with the water in auxiliary bucket 144, and siphon is divided into two portions
Point, a part is：Water in intermediate water tank 130 is reverse flowed to membrane module；Another part is：Assist bucket 144 in water along
Vacuum breaking pipe 145 enters cleaning device, and after assisting the water in bucket 144 to be sucked, vacuum breaking pipe 145 starts to inhale therewith
Enter air, air enters in top chamber A, and confined space siphon jet is caused to interrupt.Water in internal pipeline 142 is quickly fallen to auxiliary
Water tank 143 is helped, water level, which is restored to, keeps at a of Hengshui position.
So far, the dirt in membrane module is eliminated, and water flux is restored to original big flux state.
Each technical characteristic of embodiment described above can be combined arbitrarily, to keep description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
