DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] Embodiment 1:

[0021] As Figure 1 and Figure 2 shown, where Figure 1 is a schematic diagram of the overall structure of the flow electrode capacitive deionization device, Figure 2 is a schematic diagram of the stirring blade 105. The present utility model provides a flow electrode capacitive deionization device: including an insulating partition 101 and an auxiliary component. The insulating partition 101 has a water inlet 102 and a water outlet 103. The auxiliary component includes a current collector 104, a stirring blade 105, a driving motor 106, and a DC power supply 107. The two sides of the insulating partition 101 are respectively connected to the current collector 104 through an anion exchange membrane 108 and a cation exchange membrane 109. A flow electrode 110 is provided at the electrode inlet and outlet of the current collector 104. A first automatic detector 111 is provided at the water inlet 102, and a second automatic detector 112 is provided at the water outlet 103. Through the foregoing solution, it is possible to solve the problem that in the prior art, due to the influence of the fluidity and viscosity of the flow electrode 110, when the loading amount of the electrode material reaches a certain value, it is difficult to further improve, and it is easy to cause the flow channel to be blocked, resulting in a decrease in the adsorption efficiency of the flow electrode 110 for capacitive deionization, seriously affecting the operation effect. It can be understood that the foregoing solution can reduce the blockage of the flow channel and improve the adsorption efficiency of the flow electrode capacitive deionization.

[0022] In this embodiment, the insulating partition 101 has a water inlet 102 and a water outlet 103. The water inlet 102 is used for inputting the water to be treated, and the water outlet 103 is used for discharging the treated water.

[0023] Wherein, current collectors 104 are respectively connected to both sides of the insulating partition 101 through an anion exchange membrane 108 and a cation exchange membrane 109. Flow electrodes 110 are arranged at the electrode inlets and outlets of the current collectors 104. The stirring blades 105 are located in the cavities of the current collectors 104. The drive motor 106 is fixedly connected to the housing of the current collector 104, and its output shaft is connected to the stirring blades 105. The DC power supply 107 is electrically connected to the current collector 104. Both sides of the insulating partition 101 are connected to the current collector 104 through the anion exchange membrane 108 and the cation exchange membrane 109 respectively. After connection, the current collectors 104 are located on both sides. Flow electrodes 110 are arranged at the electrode inlets and outlets of the current collectors 104. Before operation, the flow electrodes 110 can be introduced into the current collectors 104. After introduction, due to the arrangement of the anion exchange membrane 108 and the cation exchange membrane 109, the flow electrodes 110 will not enter the insulating partition 101. The drive motor 106 is installed on the housing of the current collector 104 by bolts, and its output shaft is connected to the stirring blades 105. The DC power supply 107 is respectively connected to the current collectors 104 on both sides.

[0024] A first automatic detector 111 is arranged on the water inlet 102. The first automatic detector 111 is used to detect the ion content in the water to be treated input.

[0025] A second automatic detector 112 is arranged on the water outlet 103. The second automatic detector 112 is used to detect the ion content in the treated water when output. After the system compares the detection data of the second automatic detector 112 with the data of the first automatic detector 111, it is convenient for the user to know in time whether the treatment is up to standard.

[0026] Secondly, the output shaft of the drive motor 106 is connected to the stirring blades 105 through a coupling. The connecting shaft of the stirring blades 105 is connected to the output shaft of the drive motor 106 through a coupling. When the drive motor 106 operates, it can drive the stirring blades 105 to rotate.

[0027] Then, the insulating partition 101 is a tubular structure that is connected up and down.

[0028] Finally, the current collector 104 on one side of the anion exchange membrane 108 is connected to the positive pole of the DC power supply 107; the current collector 104 on one side of the cation exchange membrane 109 is connected to the negative pole of the DC power supply 107.

[0029] When using the present utility model to solve the problem in the prior art that the flowing electrode 110 is affected by its fluidity and viscosity, etc., when the loading amount of the electrode material reaches a certain value, it is difficult to further increase, and it is easy to cause the flow channel to be blocked, resulting in a decrease in the adsorption efficiency of capacitive deionization of the flowing electrode 110 and seriously affecting the operation effect. Before work, the flowing electrode 110 can be introduced into the current collector 104. After being introduced, due to the provision of the anion exchange membrane 108 and the cation exchange membrane 109, the flowing electrode 110 will not enter the insulating partition 101. Then, control the driving motor 106 to act. At this time, under the action of the driving motor 106, the stirring blade 105 in the current collector 104 starts to rotate, driving the flowing electrode 110 to circulate between the flowing electrode tank and the current collector 104. Turn on the DC power supply 107 and input the rated voltage, which can be selected as 1.2V. However, at this time, since the raw water is not introduced, the current loop is not formed. Further, introduce the raw water to be treated. At this time, the current loop is formed. In the insulating partition 101, the anions in the raw water pass through the anion exchange membrane 108 and are then adsorbed by the flowing electrode 110 at the positive electrode. The cations in the raw water pass through the cation exchange membrane 109 and are then adsorbed by the flowing electrode 110 at the negative electrode. At this time, the raw water flows out from the water outlet 103, and the treatment is completed. Thus, the problem in the prior art that the flowing electrode 110 is affected by its fluidity and viscosity, etc., when the loading amount of the electrode material reaches a certain value, it is difficult to further increase, and it is easy to cause the flow channel to be blocked, resulting in a decrease in the adsorption efficiency of capacitive deionization of the flowing electrode and seriously affecting the operation effect is solved.

On the basis of the first embodiment, the present utility model provides a flowing electrode capacitive deionization device. The auxiliary component further includes a microfiltration member 201, and the microfiltration member 201 is arranged in the circulation loop of the flowing electrode 110.

[0032] In this embodiment, by arranging the microfiltration member 201 in the circulation loop of the flowing electrode 110, the electrode liquid can be filtered when it flows back to the electrode system.

[0033] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
