Description of the Invention: [Technical Field of the Invention] The present invention relates to an electrolytic deionized water purification system, and more particularly to an electrolytic deionized water purification system capable of improving water purification effect. [Prior Art] Electro-deionization (EDI) technology is mainly used to remove charged ions in water. Its application fields include pure water production, wastewater recovery, and electroplating wastewater recovery/treatment. At present, the equipment for removing ions by electrolysis generally includes electro-dialysis ' ED, electro-dialysis reversal ' EDR, electro-deionization (EDI) and continuous electrolysis. Ion (c〇ntinuous eiectro_deionization, CEDI) system. In the case of a conventional electrodialysis (ED) or electrolytic deionization (EDI) system, it is only composed of a group of ion exchange membranes and a group of electrodes (an anode electrode and a cathode electrode) to form desalting. Structures such as chambers, concentrating chambers, and electrolysis chambers. Generally speaking, the water flowing through the electrolysis chamber and the concentrating chamber is the same water, and this month, the water can be used for a fixed time cycle, and another water will flow, and the wind will be removed. In the case of an inverted-electrode dialysis (EDR) system, it is based on the structure of an electric (I 〇) system, and the direct current and the negative electric current are fixed for a fixed period of time to δ weeks to improve the blockage of the anion-cation exchange membrane. The problem. In the case of continuous electrolytic deionization (CEDI) systems, it is mainly applied to the pure 200922881 treatment of ultrapure water. Since ultra-pure water has a poor electrical conductivity (resistance value of 18.2 Μ Ω), ion exchange resins must be filled in the desalination chamber of the continuous electrolytic deionization (CEDI) system to increase current efficiency to increase ion removal. In addition, the continuous electrolytic deionization (CEDI) system can also utilize the H+ and OH- produced by water electrolysis to continuously regenerate the ion exchange resin in the desalination chamber. In addition, regardless of the electrolytic deionization system, the driving force for removing water (charged) ions is electricity. The amount of ion migration in water can be detected from current efficiency performance, and the higher the current, the greater the amount of ion migration. That is to say, under the same operating conditions, the higher the voltage, the higher the current, and the better the desalination (or deionization) efficiency. However, increasing the voltage also means increasing the power consumption, thus increasing the operating cost. Referring to FIG. 1 , a conventional electrolytic deionization system 1 mainly includes an anode electrode 11 , a cathode electrode 12 , a first electrolysis chamber 21 , a second electrolysis chamber 22 , a first concentration chamber 31 , and a second unit .

The anode electrode 11 and the cathode electrode 12 are connected to a DC voltage source (not shown). The first electrolysis chamber 21, the first concentration chamber 31, the desalting chamber 40, the second concentration chamber 32, and the second electrolysis chamber 22 are sequentially disposed between the anode electrode 11 and the cathode electrode 12. The first electrolysis chamber 21 is connected to the anode electrode 11, and the second electrolysis chamber 22 is connected to the cathode electrode 12. In particular, the first concentrated 8 200922881 chamber 3] is blocked by the first cation exchange membrane (10) such as #-ne, CEM)ci and the - anion exchange membrane (four) (10) - mb brain, AEM) A1 Formed in the first electrolysis chamber u and between two to 40, and the second retraction chamber 32 is formed in the desalting chamber by a second cation exchange membrane C2 and a second anion exchange membrane VIII. Between the second transfer chamber 22 and the second transfer chamber 22, the transfer of the parent (4), the intermediate anion exchange membrane A1, the second cation exchange membrane C2, and the second anion exchange 2 A2 are sequentially disposed between the anode electrode u and the cathode electrode 12. The inlet passage 51 can be connected to the bottom of the desalination chamber 40, and the first 52 can be connected to the top of the desalination chamber 4〇. Incoming water pump 60 is Π / - MM51, which can transport the water to be treated to the desalination chamber 52. The water that has been treated in the Φ desalination chamber 4 is output through the first outlet pipe 52.卜吕第-= is connected to the first solution chamber 2, the first concentrating chamber 3, the Buer/Chen chamber 32, and the 筮-Thunder a between the circulation lines 7Π. The circulating pump 8 is the deflation chamber 31, the second two: this - the first electrolysis chamber 21' is first circulated twice; the water in the second and second electrolysis chambers 2 2 can be Constantly more frontal h hunter is discharged by a younger water outlet pipe 92.

At the same time, the anion V θ is permeable to the anion exchange membrane A1 and enters the first concentration : ' and the anion Β - cannot penetrate the first cation exchange 臈 c to stay in the first concentrating compartment 31. As described above, due to the desalination chamber, the anions and cations (Β_, Α+) in the water are respectively moved into the first concentrating chamber 31 and the concentrating chamber 32. Therefore, the water in the desalting chamber 40 can achieve the effect of desalination or water purification. . That is, the water output from the desalination chamber 40 via the first outlet pipe 52 has good water quality. The value of s 4 is that the main driving force of the electrolytic deionization system 1 is the power 'and thus must continue to consume electricity to achieve desalination (or water purification). In more detail, the amount of migration of anions and cations (B_, A+) in water ^ 10 200922881 is known from the current value. The larger the current value, the more representative of the anion and cation (the larger the migration amount of b_. In other words, the greater the DC current in the electrolytic deionization system 1 under the same operating conditions, the higher the current value is, the better the mouth can be. Desalination (or water purification) effect. However, the two-current voltage represents an increase in electrical energy consumption, which increases the overall operating cost of electrolysis away from 1. In addition, it is more important that the water itself is at $=body.

(not shown = electrode Π 0 and cathode electrode 12 〇 is connected to the DC voltage source. The reaction tank body 130 has a first electrolysis chamber 13 - a 132, a desalting chamber 133, a first -, and a condensed palace n - / , a hundred to a fine to 34, a second electrolysis chamber] 35, 13 200922881 an anion exchange membrane 136, a cation exchange membrane 137, a first barrier membrane 138 and a second barrier membrane 139. The electrolysis chamber 131, the first concentrating chamber 132, the desalting chamber 133, the second concentrating chamber 134, and the second electrolysis chamber 135 are sequentially disposed between the anode electrode n〇 and the cathode electrode 〇2〇, and the first electrolysis chamber (3), - Concentration chamber 132, demineralization chamber 133, second concentration chamber 134 ^ The second electrolysis chamber 135 contains water. The first electrolysis chamber 131 is connected to the anode electrode 110' and the second electrolysis chamber 135 is connected to the cathode electrode 12 The anion exchange membrane 136 is disposed between the first concentration chamber 132 and the desalting chamber 133 =, the cation exchange membrane 137 is disposed between the second concentrated crucible 134 and the desalting f 132, and the first barrier membrane 138 is disposed in the first electrolysis Between chamber 131 and first concentrating chamber 132, and second barrier membrane 139 is disposed at ^ = Between 135 and the second concentrating chamber 134. That is, the first concentrating chamber 132 is blocked by the anion exchange membrane 136 and the first barrier membrane 138: forming: between the desalting chamber 133 and the first electrolysis chamber 131, The second concentrating chamber 134 is separated between the secrude desalination chamber 133 and the second electrolysis chamber 135 by the cation exchange membrane 137 and the second barrier membrane 139. In the present embodiment, the first barrier membrane 138 and the first The second barrier film 139 may be ion exchanged, or the first barrier 138 and the second barrier 139 may be a cation exchange membrane and an anion exchange membrane, respectively. Further, in particular, the desalting compartment 133 is filled with a plurality of The first electric conductor D can be selectively filled with a plurality of second guides, and the body D2 and the __concentrating chamber can be selectively filled with a plurality of third electric conductors. 3. The first conductor m, the second conductor, and the third conductor D3 may be made of activated carbon, carbon nanotubes, graphite or metal material 14 200922881, etc. In addition, the first concentrating chamber 132 and the second The concentrating chamber 134 can also be selectively filled with a plurality of ion exchanges The ion exchange resin E may be an anion exchange resin (RQH.) and a cationic cross-linking grease (Rh+). ^ The first water inlet pipe 140 is connected to the desalination chamber 133. In more detail, the first The water line 140 is connected to the bottom of the desalination chamber 133, and the water inlet pump 145 is connected to the first water inlet line 140, which can transport the water to be treated into the desalination chamber 〖33. 7 &amp; Connected to desalting to 1: ^. In more detail, the 'first-water outlet line 150 is connected to the top of the desalting f 133, ' to transport the treated water from the desorption i 133 to the outside of the reaction tank . The %-passage line 160 is connected to the first electrolysis chamber 131, =, the second: the agricultural shrinkage chamber (9) and the second electrolysis chamber 135. The circulation pump = Γ A is above the 16% official road to drive the first electrolysis chamber 131, the first to 132, the second concentration t 134 and the second electrolysis $ 135 to circulate. The supplementary read 17G is connected to the circulation line I6G, and the second inlet pipe (10) is connected to the supplementary water tank no. The circulation line 16 is provided with a second water outlet line 19G. As described above, the external water can be sent to the replenishing water tank 170 via the second water inlet wheel, and thus can be replenished into the circulation pipe_, or the water in the circulation line 160 can be passed through a valve member (not shown). The second system is selected to be discharged through the second water outlet pipe 19, thereby achieving the purpose of water-saving = and thus avoiding the first electrolysis chamber 131, the first concentration to 132, the second concentration crucible 134, and the second electrolysis chamber. The fouling produced in 135 is now 200922881 ^ (that is, the fouling blockage phenomenon on the anion exchange membrane 136, the cation exchange membrane 37, the first barrier membrane 38) and the second barrier membrane 139 can be avoided. When the anode electrode 110 and the cathode electrode 12 are applied with a DC voltage or current, the anode electrode 110 and the cathode electrode 120 pass through the first electrolysis chamber first concentration chamber 132, the desalting chamber 133, the second concentration chamber 134, and the second electrolysis. The water in chamber 135 is turned on. The cation A in the water in the desalting compartment 133 is attracted by the cathode electrode 12 而 and moved toward it, and the anion B- in the water in the desalting compartment I% is attracted by the anode electrode 11 而 and moved toward it. At this time, the cation A+ penetrates the cation exchange membrane 137 and enters the first, concentrating chamber 134, and can be adsorbed by the ion exchange resin E in the second concentrating chamber 134 (for example, the cation A+ can be combined with the cation exchange resinist +) The reaction produces RA+ and H+). At the same time, the anion B- will penetrate the anion exchange membrane 136 and enter the first concentration chamber 132, and may be adsorbed by the ion exchange resin E in the first concentration chamber (3) (for example, the anion B· can be combined with the anion exchange resin The (ROH-) reaction produces RB- and 〇H-). As described above, since the anions and cations (β·, α+) in the water in the 133 are moved to the first 钿 to 132 and the second concentrating chamber 134, respectively, the water in the desalting chamber can be To achieve desalination (or water f purification) m on μ 1 (four) to 133,. The water produced by 帛$水营路15〇 will have good water quality. As described above, since the first conductor D, the second conductor D2, and the third conductor D3' are filled in the desalination chamber 133, the first concentrating chamber 132, and the second condensing chamber 134, respectively, the entire reaction tank (10) The conductivity will increase. In more detail, even if the water itself is a poor conductor, due to the presence of the first conductor D1, the second conductor D2, and the third conductor D3, 200922881 = current in the deionized water quality system 2 (8) Efficiency will be greatly improved. In other words, the overall resistance value in the reaction tank body 13G is greatly reduced, so that the current value conducted to the reaction tank body 13 (4) is greatly increased, and the anion and cation in the water in the desalination chamber 133 (B., A+) are caused. ) respectively, the number and speed of migration from the first/next I_132 and the second concentrating chamber 134 are increased, and the anion and cation in the water of desalting t 133 β (B-, eight scoops = the number of shifts and the speed increase) In this case, the effect of desalting and massification of the water in the desalination chamber 133 is improved. That is to say, the electrolysis deionized water f purification system (10) can be produced without increasing the application of the direct pressure (4), thereby reducing the electric energy and lowering the operating cost. In addition, when the first conductive material filled in the desalination chamber 133 is activated carbon, in addition to increasing the overall guide body of the reaction tank m, the organic matter in the water can be simultaneously removed, thereby further improving the water purification. effect. Furthermore, although the electrolytic deionized water purification system of the present embodiment is desalted, the first concentrating chamber 132 and the second concentrating chamber 134 are actually filled with the first conductor D1 and the second conductor D2. The third electrical conductor can be filled with the first electrical conductor m only in the desalting chamber 133, or the second electrical conductor is filled into the second electrical conductor and the third electrical conductor D3 also enhances the overall penability of the reaction tank 13G. In addition, the electrolytic deionized water purification system 100 of the present embodiment is not.
