Description
Technical field
The present invention relates to water treatment field, specifically a kind of electrically driven (operated) film desalination unit and using the unit
Method for treating water.
Background technology
Electrodialysis, abbreviation ED methods, it is to be alternately arranged using anions and canons exchange membrane between positive and negative electrode, and with special
Dividing plate separated, composition desalination desalination and concentration two systems.After people's salt solution is led to compartment, acted in DC electric field
Under, cation migrates to negative pole, and can only migrate, can only be handed over by anion to positive pole by cation-exchange membrane, anion
Film is changed, and is desalinated the salt solution in light room, the salt solution in dense room is concentrated.But in the process of running, due to negative electrode and dense
Room is in alkaline, scale formation easily occurs on the film of negative electrode pole room and dense room both sides, so as to influence effluent quality, and shortens equipment
Service life.Subsequent frequently pole-reversing electroosmosis (abbreviation EDR) is born, and its appearance is the once great prominent of electrodialytic technique
It is broken., by switching polarity of electrode and coordinating the switching in water route, the water drainage-supply system for realizing light room and dense room is changed, and makes equipment for it
Call oneself and generate self-cleaning ability --- dense room and negative electrode are changed into acid being extremely changed into light room and anode, acid-base property afterwards from alkalescence
Property, the dirt tied is acid washed to come off to be gone out with current.The long-time stability of amberplex are so ensure that, in turn ensure that out
The stabilization of water water quality.
Current electric dialyzator main body forms by locking frame, water dispensing board (and battery lead plate), porous plate and membrane stack.Locking
Frame is welded by square steel tube or channel-section steel one kind.Water dispensing board is made using pvc plates, plays a part of to guide dense, fresh water disengaging membrane stack,
Battery lead plate is then for fixed electrode, and generally both plates can merge.Porous plate is equally made using pvc plates,
Play a part of to protect membrane stack, enclosed electrode room.Membrane stack is generally according to pole film (anode membrane) --- dividing plate --- cavity block --- every
--- --- dividing plate ... cavity block --- dividing plate --- pole film (anode membrane) arranges anode membrane plate.
At present, the problem of prior art is present be：
1. the control of falling pole of current frequently pole-reversing electroosmosis is not accurate enough.
2. lacking effective pressure protection measure, often occur due to intermembranous damaged drainage caused by hypertonia.
3. existing electric dialyzator locking frame directly clamps the water dispensing board of pvc materials, low intensity, easily there is asking for sheet material fatigue
Topic.
4. because water dispensing board and porous plate are made using pvc plates, and pvc plates belong to soft material, and the thickness of plate is uniform
Differ, plate face cut easily occurs in processing, if the cut of appearance is dealt with improperly, can destroy sealing surface, cause oozing for pole water
Leakage.
5. current vertical electrodialysis, the Inlet and outlet water of electrode hangs down using laterally leaking water with its water (flow) direction in a device
Directly, on the one hand it is unfavorable for excluding the gas in electrode chamber, being on the other hand unfavorable for the when of falling pole goes out the dirty body to come off in electrode chamber.
6. existing electric dialyzator membrane stack both sides film body is directly exposed, shortage is effectively protected.
7. lack traffic protection measure, membrane stack often occur due to block cause underfed and caused by burn film phenomenon.
8. existing frequently pole-reversing electroosmosis typically uses the form of one section of one-level, though control is simple, floor space is big, pipe
Road is complicated.
