Brief description
Fig. 1 is the structural representation for one embodiment of the utility model is described；
In figure, 1 be first-stage reverse osmosis unit, 2 be edi unit, 21 be freshwater room, 22 be concentrated water room, 3 be inlet channel, 4
For the first pipeline, 5 be intake pump, 6 be second pipe, 7 be mixed bed unit, 8 be outlet conduit, 9 be first-stage reverse osmosis product water tank,
10 is reverse osmosis concentrated water discharge tube, 11 is edi concentrated water discharge pipeline.
Specific embodiment
The concrete effect of the unit that the utility model system is formed, with the ultra-pure water system used in prior art
Standby device is essentially identical, particularly as follows:
Reverse osmosis technology is to rely on reverse osmosis membrane to make the solvent in solution carry out detached process with solute under stress.?
In this technique, as the processing equipment before edi, remove in eliminating water the strong zwitterions of great majority and partly weak zwitterion.
Edi technology is to pass through effect and ion exchange resin by anions and canons exchange membrane to the selectivity of anions and canons
Exchange interaction to ion, realizes the directional migration of ion in the presence of DC electric field, thus completing the deep desalting of water.?
While carrying out desalination, the hydrogen ion that water power dissociation produces and hydroxide ion regenerate to ion exchange resin, therefore not
Soda acid chemical regeneration is needed can continuously to produce ultra-pure water.In the art, as the processing equipment before mixed bed, continue in removing water
Zwitterion, reduce mixed bed load, extend mixed bed the cycle of operation.
Mixed bed technology is that a certain proportion of cationic, anionic exchange resin is mixed loaded in same switch, convection current
Ion in body swaps, removes, and reaches the purpose of deep desalting.
Below in conjunction with the accompanying drawings the utility model is further elaborated
With reference to shown in Fig. 1, an embodiment of the present utility model is a kind of ultrapure water process deep desalting system, and existing
Ultra-pure-water treatment system in technology is similar, needs including first-stage reverse osmosis unit 1 and edi unit 2 in this system, and one-level
Reverse osmosis units 1 are connected with inlet channel 3；What is more important, aforementioned first-stage reverse osmosis unit 1 need to pass through the first pipeline 4
Be connected with edi unit 2, and also need to set up intake pump 5 on the first pipeline 4, simultaneously edi unit 2 also by second pipe 6 with
Mixed bed unit 7 is connected, then this mixed bed unit 7 is connected with outlet conduit 8, consequently, it is possible to then by first-stage reverse osmosis unit
1st, edi unit 2 and mixed bed unit 7 are serially connected in same system operation successively.
