Description
Technical field
The invention belongs to water-treatment technology field, relate to current bufferings and water purification backwashing technology, relate in particular to for the air bag of water treatment and with the purifier of air bag.
Background technology
The membrane separation technology be take pressure as impellent, the physics material sieving technology that utilizes the aperture of filter membrane that liquid is separated, applicable to from the inorganics to the organism, from bacterium to virus, from the particulate to the molecule, the extensive separation of ion.
Membrane separation technique belongs to physical process, need not add chemical agent, can not produce secondary pollution, belongs to " green " water conditioning technology, is widely used in the purifying treatment of water quality.
In the process of membrane separation, there is the problem of following two aspects:
1, owing to the crown_interception of filter membrane, part is trapped thing and can be attached to the filter membrane surface, and fenestra also can be stopped up by the more tiny thing that is trapped, and causes the membrane flux of filter membrane to descend;
2, intake pressure rises too fastly, can damage filter membrane, presses hollow fiber ultrafiltration membrane in particularly, and rising water pressure is too fast, can break through, thrust hollow fiber film thread, and former water directly enters in the water purification by the film silk of breakage, affects the water purification quality.
In order to keep the good membrane flux of filter membrane, need regularly filter membrane to be cleaned.The method of cleaning comprises surface washing, back flushing, matting etc.
Surface washing refers to allow former water wash away fast the filter membrane surface, washes out and take away the dirt that is attached to the filter membrane surface.
Back flushing refers to allow current see through filter membrane by the opposite direction of normal filtration, washes out and take away the dirt that is blocked in the dirt in the fenestra and is attached to the film surface.
The surface washing of filter membrane, as long as just can realize that at sewage draining exit of filter housing increase and wash water valve that filter membrane is installed the tiny dirt that is blocked in the fenestra can't is washed off in punching, effect is limited.Use a plurality of valves or multiway valve to carry out back flushing with former water, not only pipeline is complicated, also can the water purification side of filter membrane be polluted.
Chinese patent literature [publication number: CN1147971] disclosed " water-purification plant " adopts at a water purification storage of the water pipeline connection pressure device of purifier and has realized the water purification back flushing.This water purification storage pressure device is a built-in water pocket, the seal closure of filling non-active gas, water purification in conduit enters the water pocket of water purification storage pressure device, the non-active gas in the compression seal cover simultaneously.As required, in the water pocket under the extruding of water purification non-active gas in seal closure of storage, can adverse current to filtering material, filtering material is washed.

(2) volume of water purification storage pressure device, pressure water storage tank is large, cost is high, is not suitable for adopting in the limited purifier of volume, cost.
Chinese patent literature [publication number: CN102247722A] disclosed " a kind of air type permanent backwash filter that do not dissolve ", the air bag that usefulness places filter core to purify the chamber has been realized the water purification back flushing to filter core.This technical scheme " for allowing back flushing reach preferably effect, resistance to air loss elastic diaphragm vapour barrier layer preferably adopts the high-quality resilient materials such as silica gel, also can adopt other nontoxic or food grade elastic caoutchoucs, also can adopt other elasticity airtight materials such as plastics etc. ".
In fact, the air bag that adopts rubber, plastics film to make, the gas in the air bag can see through film to exosmosis, and the gas barrier properties of food grade rubber (such as silica gel), elastic plastic film is all very poor, elasticity is better, pressure is larger, and gas-permeable ease mistake rate is just higher.The air bag that adopts above-mentioned patent [publication number: CN102247722A] technical scheme to make, place the water 3 months of 0.2～0.3MPa, gas in the air bag can permeate ease and lose about half, do not reach the beneficial effect of " can overcome tradition utilizes air to carry out the deficiency of back flushing; air and water purification are separated; do not allow water and air contact to avoid air dissolves in water purification; to reach the permanent preservation of air " that this patent specification writes, although can reduce " number of times of periodic replacement filter core " and " trouble of manual backwashing ", increase number of times and the cost of periodic replacement air bag.
Than the less reverse osmosis membrane in ultra-filtration membrane aperture, the easier obstruction that is subjected to dirt.In the process of reverse osmosis membrane work, can produce a large amount of condensed water, immediately take away separated solute, prevent that separated concentrated solute is in the fouling of reverse osmosis membrane surface deposition.Behind reverse osmosis water end of processing processed, the condensed water in the reverse osmosis membrane if can not in time wash discharge, also can in the fouling of reverse osmosis membrane surface deposition, affect membrane flux and the work-ing life of reverse osmosis membrane.
