Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to an EDI (Electronic Diode) water inlet / outlet adapter. Background Technology

[0002] Electrodeionization (EDI) is a pure water preparation technology that combines ion exchange, ion exchange membrane, and ion electromigration technologies. It cleverly combines electrodialysis and ion exchange, using high voltage at both electrodes to move charged ions in the water, and employing ion exchange resins and selective resin membranes to accelerate ion removal, thereby achieving water purification.

[0003] EDI membrane stacks typically consist of a cathode plate, an anode plate, and multiple sets of alternately arranged filter membranes, forming a concentrate chamber and a dilute chamber. When the electrode water comes into contact with the anode plate, it generates corrosive gases. If these gases are discharged directly without proper treatment, they will contaminate the entire tank of water upon recirculation. Utility Model Content

[0004] Therefore, it is necessary to provide an EDI water inlet / outlet adapter that can effectively neutralize corrosive gases and other gases in water, addressing the aforementioned technical problems.

[0032] An EDI electrode water inlet and outlet adapter is described below in conjunction with FIGS. 1-7.

[0033] As shown in FIGS. 1, 2 and 3, in one embodiment, an EDI electrode water inlet and outlet adapter includes oppositely arranged anode multifunctional plate 100, cathode multifunctional plate 200, exchange membrane group 300 between anode multifunctional plate 100 and cathode multifunctional plate 200, and electrode water adapter 400 for distinguishing water paths.

[0034] Referring to FIG. 4, anode multifunctional plate 100 has water inlet hole 101, water outlet hole 102 and first groove 110, and second groove 120 is inwardly extended from the bottom of the groove of first groove 110, and water inlet hole 101 and water outlet hole 102 are respectively located at both ends of the groove wall of second groove 120 and penetrate through second groove 120.

[0035] Cathode multifunctional plate 200 is oppositely arranged with anode multifunctional plate 100; and cathode multifunctional plate 200 provides required electric energy for ion exchange in water after being electrified with anode multifunctional plate 100.

[0036] The exchange membrane group 300 includes a cation exchange membrane 310, an anion exchange membrane 320, a resin plate 330, and a diaphragm 340, the cation exchange membrane 310 and the anion exchange membrane 320 are respectively located on both sides of the resin plate 330, and the diaphragm 340 is located between the cation exchange membrane 310 and the anode multifunctional plate 100 and is embedded in the first groove 110.

[0037] The cation exchange membrane 310 does not allow anions and water to pass through, the anion exchange membrane 320 does not allow cations and water to pass through, and through the selective permeation of the cation exchange membrane 310 and the anion exchange membrane 320 and the ion exchange of the resin plate 330, under the action of a direct current electric field, the directional migration of ions is realized, thereby completing the deep desalination of water, and the hydrogen ions and hydroxyl ions generated by the electrolysis of water regenerate the resin plate 330.

[0038] The polar water adapter 400 is fixedly installed in the water inlet hole 101 and the water outlet hole 102 respectively, and the polar water adapter 400 is provided with a first channel 410 and a second channel 420, which will be described below Figure 2 , specifically, the first channel 410 and the second channel 420 are both provided with a one-way valve 430, and the conduction directions of the one-way valves 430 in the two channels are opposite. The adjacent second channels 420 are provided with a gas treatment device 500.

[0039] Because the surface of the anode multifunctional plate 100 is added with a rare metal coating, when electrified, it reacts with water to form hydrogen ions, oxygen, chlorine, and corrosive gases, among which hydrogen and oxygen will form bubbles, which will gradually accumulate in the closed EDI membrane stack to increase the internal pressure, and the corrosive gases will cause pollution to the water tank after backflowing with water, so the gas treatment device 500 is needed for comprehensive treatment, the gas treatment device 500 includes a degassing membrane device 510 and a dechlorination device 520, the degassing membrane device 510 is respectively communicated with the second channels 420 of the two polar water adapters 400, and the dechlorination device 520 is installed between the polar water adapter 400 in the water inlet hole 101 and the degassing membrane device 510, the oxygen, chlorine, and corrosive gases generated by the polar water passing through the anode multifunctional plate 100 are separated from the water by the degassing membrane device 510 using the osmotic pressure principle for further treatment and comprehensive treatment, and the degassed water passes through the dechlorination device 520 again and then returns between the anode multifunctional plate 100 and the cathode multifunctional plate 200 to complete the deep electrolysis of water.

[0040] The EDI electrode water adapter of the embodiment pumps the electrode water between the anode multifunctional plate 100 and the diaphragm 340 through the first channel 410 of the electrode water adapter 400 in the water inlet hole 101. The electrode water first reacts with the anode multifunctional plate 100 to generate hydrogen ions, oxygen, chlorine and corrosive gas, and enters the gas treatment device 500 through the second channel 420 of the electrode water adapter 400 in the water outlet hole 102 under the action of pressure for comprehensive treatment. The degassed electrode water enters between the cation exchange membrane 310 and the anion exchange membrane 320 through the second channel 420 of the electrode water adapter 400 in the water inlet hole 101 after the resin plate 330, and then flows out from the first channel 410 of the electrode water adapter 400 in the water outlet hole 102, so as to meet the requirement of high-purity water.

[0041] On the other hand, the anode multifunctional plate 100 generates a large amount of heat energy during work. The electrode water first contacts the anode multifunctional plate 100, which effectively plays a role of heat dissipation.

[0042] As shown in FIG. 4, in an embodiment, the groove wall of the second groove 120 is equally provided with a water distribution strip 121. The water inlet hole 101, the water outlet hole 102 and the water distribution strip 121 are provided with a water guide strip 122.

[0043] The electrode water between the anode multifunctional plate 100 and the diaphragm 340 is guided once by the water distribution strip 121, and can be uniformly distributed on the water guide strip 122. The water guide strip 122 divides the water flow to improve the use performance of the device.

[0044] As shown in FIG. 5 and FIG. 6, in an embodiment, the resin plate 330 includes a plate body 331 and a resin film 332. The resin film 332 is tensioned in the plate body 331. The upper and lower ends of the plate body 331 are both provided with through holes 333, which correspond to the electrode water adapter 400.

[0045] The diaphragm 340 is provided with a mounting hole 341 corresponding to the electrode water adapter 400. A waterproof gasket 342 is arranged between the inner wall of the mounting hole 341 and the electrode water adapter 400.

[0046] The groove wall of the first groove 110 is provided with a convex rib 111. When the diaphragm 340 is placed in the first groove 110, the convex rib 111 abuts against the diaphragm 340.

[0047] When the EDI module is running, the first groove 110 limits the position of the diaphragm 340, and functions as a fixing part to avoid the diaphragm 340 from moving on the anode multifunctional plate 100, the convex rib 111 and the waterproof gasket 342 can abut against the diaphragm 340, thereby improving the sealing property of the diaphragm 340 and preventing water from seeping out from the edge gap of the diaphragm 340. In actual application, the second channel 420 of the inner pole water connector 400 in the water inlet hole 101 and the first channel 410 of the inner pole water connector 400 in the water outlet hole 102 are slightly protruded from the surface of the inner pole water connector 400, so that the second channel 420 of the inner pole water connector 400 in the water inlet hole 101 and the first channel 410 of the inner pole water connector 400 in the water outlet hole 102 can extend into the through hole 333 of the plate body 331, thereby realizing the transmission of water flow.

[0048] As shown in Fig. 7, in one embodiment, the first channel 410 and the second channel 420 of the inner pole water connector 400 in the water inlet hole 101 are provided with an inclined angle α, 30°<α<45°, preferably, α is 35°, so that the water inlet can increase some water inlet force and help to control the flow.

[0049] The technical features of the above-described embodiments can be combined arbitrarily, and for the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not contradict, they should be considered as the scope of the present disclosure.

[0050] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
