Embodiment 1

[0021] Embodiment 1. Application in purification and concentration of liquid, such as desalination technology in seawater desalination. Let's take the separation of sodium chloride (NaCl) solution as an example to demonstrate seawater desalination:

[0022] The first step: as attached figure 1 As shown in the sodium chloride (NaCl) solution storage container 1 at this time, the concentration of the sodium chloride (NaCl) solution (brine) 2 is 10%, and when there is no electric field, it is injected into the container 7 through the liquid inlet pipe 3 Sodium Chloride (NaCl) Solution 2. At this time, the Cl in solution 2 - and Na + Ions are randomly distributed. That is, Cl - and Na + The ions are equally likely to appear in the container.

[0023] The second step: as attached figure 2 As shown, the two insulating separators 5 are raised. At this time, the solutions 2 in the three regions can communicate with each other; now, a 1KV DC voltage is applied to the plates 4 ...

Embodiment 2

[0029] Embodiment 2, the application in electrochemistry, such as splitting water, producing the application of hydrogen and oxygen.

[0030] Step 1: Because water itself can also be ionized into H+ and HO- ions, if attached Figure 7 The container 10 is shown containing water.

[0031] Step 2: Apply DC (preferably static electricity) high voltage to the outside of the container 10 to generate a strong electric field inside the container 10 . as attached Figure 8 As shown: when K2 is closed, the H+ ions and HO- ions in the water in the container 10 will also gather near the two polar plates 12 and 13.

[0032] The third step: as attached Figure 9 As shown, under the condition that the strong electric field is not cancelled, the solution in which H+ ions and HO- ions are distributed is isolated by a sealed partition 11 .

[0033] Step 4: As attached Figure 10 Shown: disconnect K1, K2, cancel the external electric field. In this way, the charged H+ and HO- ions gather n...

Abstract

A process for immobilizing ions by electric field to de-concentrate and concentrate solution of preparing hydrogen gas and oxygen gas from water includes such steps as loading the solution in a container with positive and negative plate electrodes on its external surface, applying a DC voltage across said positive and negative electrodes to generate an electric field for attracting the cations and anions to relative electrodes, isolating the central de-concentrated solution from the peripheral concentrated solution by a partition, and respectively taking the de-concentrated solution and concentrated solution.

Description

technical field [0001] The electric field immobilized ion separation method of the present invention relates to a method of using electric field immobilized ions to desalinate and concentrate the solution, and to separate water to generate hydrogen and oxygen. Background technique [0002] At present, relatively mature seawater desalination technologies at home and abroad include: 1. Reverse osmosis membrane seawater desalination technology; 2. Low-temperature multi-effect distillation seawater desalination technology; 3. Pressure steam distillation seawater desalination technology; 4. Multi-stage flash seawater desalination technology; 5. Electrodialysis; 6. Freezing, etc. However, current seawater desalination is limited by problems such as high cost, small scale and high energy consumption. [0003] At present, there are more deliberate technologies in the separation of water to produce hydrogen and oxygen at home and abroad: 1. Electrolysis of sodium hydroxide solution;...
