Description
Technical field
The present invention relates to a kind of water purifiers and a kind of cleaning method, specifically, are related to a kind of automatic cleaning of water purifier
Device and cleaning method.
Background technology
Ultrafiltration membrane water purifier can effectively cross the polluters such as colloid, iron rust, sandstone, red worm, the bacterium in drainage, use
A large amount of polluters are trapped on the outside of ultrafiltration membrane after a period of time, can influence the service life of water yield and film wire.And it cleans
Two ways is generally used when ultrafiltration membrane, one is chemical dosing cleanings, and one is physical cleanings.Chemical dosing cleaning is by film
Silk is immersed in chemical agent solution, and the polluter on film wire surface reacts the decomposition that falls off with chemical agent, to reach cleaning
Purpose.Chemical cleaning can effectively restore water yield, but the cleaning process is complicated, consume medicament, and chemical agent is to ultrafiltration
The service life of film also will produce influence.Physical cleaning generally has positive flushing and back flush, only relies on flushing, ultrafiltration membrane production
Water performance recovery is poor, and the key factor of physical cleaning is mechanical strength, and intensity is low, and degree of cleaning is inadequate, and intensity is excessively high can be broken
Bad film wire.Therefore improvement physical cleaning mode is the key that improve physical cleaning effect.

Mouth 8 and ultrafiltration membrane cylinder water inlet 7 enter ultrafiltration membrane cylinder 2, and accessing pending water reaches outside film wire 6, and filtration and infiltration enters inside film wire,
The mouth of a river 4, which is produced, by ultrafiltration membrane cylinder produces water for using.
When 6 surface contamination of film wire, into wash phase.Wash bowl inlet valve C1, ultrafiltration membrane cylinder drain valve C4 are closed, clearly
Washing cylinder upper inlet valve C3, wash bowl drain valve C2 are opened, and the water in wash bowl 9 is discharged, wash bowl upper inlet valve C3 is turned off,
Wash bowl drain valve C2, opens wash bowl inlet valve C1, ultrafiltration membrane cylinder drain valve C4, and water inlet passes through wash bowl by water inlet manifold 10
Inlet valve C1, into wash bowl 9, the gas in wash bowl 9 is pressed through wash bowl upper outlet 8 and ultrafiltration membrane cylinder water inlet 7
Into ultrafiltration membrane cylinder 2, gas generates pressure due to compression, can in the form of bubbles pour in ultrafiltration membrane cylinder 2, bubble is to film wire table
Face carries out mechanical disturbance and surface and cleans, the polluter on film wire surface fall off after as air-water mixture passes through ultrafiltration membrane together
Cylinder drain valve C4 and total drain valve C5 discharges, complete cleaning.
Wash bowl upper inlet valve C3 when production water uses again, wash bowl drain valve C2, ultrafiltration membrane cylinder drain valve C4 are closed, clearly
Washing cylinder inlet valve C1 is opened.
This technique is manually operable, and also can realize timing automatic cleaning by solenoid valve and automatic control system.
Compared with prior art, the present invention has the advantages that：
1. being not necessarily to dosing, physics cleaning is that can reach the effect of chemical cleaning.
2. using mixing wastewater with air disturbance cleaning, water is more saved in more currently used positive flushing, and effect becomes apparent from.
3. simple structure, easy to operate.
Description of the drawings
Fig. 1 embodies the structural schematic diagram of automatic flushing device.
