Background
Electrolysis is an important industrial production method that uses electrochemical reactions occurring at the interface between an electrode as an electron conductor and an electrolyte as an ion conductor to perform synthesis of chemicals, production of high-purity substances, and treatment of the material surface. When the power is on, cations in the electrolyte move to the cathode to absorb electrons, and a reduction reaction is carried out to generate new substances; the anions in the electrolyte move to the anode to release electrons, and oxidation reaction occurs to generate new substances.
Common electrolytic processes include water electrolysis for hydrogen production, oxygen production, brine electrolysis for alkali production, electrolytic purification in the metallurgical industry, surface processing electroplating and the like.

The existing method for reducing the electrolysis energy consumption comprises the following steps: cooling, reducing the distance between the positive electrode and the negative electrode, increasing the conductivity of the electrolyte and the like. However, these methods are still not ideal for reducing energy consumption, and thus the reduction of energy consumption is still a significant problem to be solved in the field of electrolytic processes.

Detailed Description
Example 1
The embodiment provides an electrolytic device with an ion trap, as shown in fig. 1, the electrolytic device comprises an electrolytic tank 1, an anode 2 and a cathode 5, an auxiliary electrode 4 is further arranged in the electrolytic tank 1, the auxiliary electrode 4 comprises a conductor part 6, an insulating shell 7 is wrapped outside the conductor part 6, and the insulating shell 7 can completely insulate the conductor part 6 from an electrolytic system. The conductor portion 6 communicates with a power source to which a voltage is applied via a wire. The auxiliary electrode 4 is located between the anode 2 and the cathode 5.
When the electrolytic device works, cations in the electrolyte 3 move to the cathode 5, anions move to the anode 2, electrons are stripped from the anions on the surface of the anode 2 to form a new substance, and cations with missing electrons are generated, so that at the moment, the anions and the cations on the surface of the anode are rich in substances which are generated by newly losing electrons, and the substances are easily recombined into stable substances to release a large amount of heat, so that electric energy is consumed. When the auxiliary electrode is applied with a voltage having a lower potential than that of the anode 2, the electric field formed between the auxiliary electrode 4 and the anode 2 rapidly drives the cations generated on the surface of the anode 2 to the vicinity of the auxiliary electrode 4, thereby greatly reducing the heat generated in the vicinity of the anode 2. When the cations near the auxiliary electrode 4 reach saturation, a voltage higher than the potential of the cathode 5 is loaded on the auxiliary electrode 4, and at the moment, the cations near the auxiliary electrode 4 rapidly move towards the cathode under the drive of an electric field between the auxiliary electrode and the cathode, and meanwhile, the anions near the cathode 5 are also driven near the auxiliary electrode 4, so that the temperature and energy consumption of the cathode 5 area are reduced.
Example 2
This example was modified on the basis of example 1 for a diaphragm-free electrolyzed water system, as shown in FIG. 2. Specifically, a partition plate 8 is arranged between the anode 2 and the cathode 5, the upper space of the electrolytic tank 1 is divided into an anode gas collecting space 9 and a cathode gas collecting space 10, and a communicated space is arranged below the partition plate 8, so that electrolyte 3, anions and cations can pass through freely. The auxiliary electrode 4 is disposed in the communication space below the separator 8.
The device of this embodiment works: a voltage is applied between the anode 2 and the cathode 5, the anode 5 is applied with a positive voltage, the cathode 5 is applied with a negative voltage, and the electrolysis phenomenon occurs. When hydroxide ions generated by nascent oxygen are produced in a large quantity in the area of the anode 2, the voltage is applied between the anode 2 and the cathode 5, and a potential lower than that of the anode 2 is immediately applied to the auxiliary electrode 4, at this time, the hydroxide ions are gathered to the auxiliary electrode 4, after the gathering is completed, the auxiliary electrode 4 is disconnected from the applied potential to release the hydroxide ions, and then the voltage is applied between the anode 2 and the cathode 5 again, and the above-mentioned processes are repeated continuously.
The voltage control process is shown in fig. 3, wherein curve a is a voltage curve applied between the anode and the cathode, and curve b is a potential curve applied to the auxiliary electrode 4 lower than that applied to the anode.
In the figure, a voltage is alternately applied between the anode 2 and the cathode 5 and between the auxiliary electrode 4 and the anode 2. Since the auxiliary electrode is insulated from the electrolyte, its voltage curve is not a square wave. In the curve a, the electrolytic tank 1 is in an electrolytic oxygen production state at the peak part moment, the area near the anode 2 is enriched with nascent oxygen and hydroxyl ions, when the curve b is in a valley state, the curve b is in a peak value, the auxiliary electrode 4 is loaded with a potential lower than that of the anode, and the hydroxyl ions in the area near the anode are driven to the vicinity of the auxiliary electrode 4 by an electric field, so that the concentration of the hydroxyl ions near the anode is reduced, a low hydroxyl concentration environment is provided for increasing the electrolytic efficiency for the next voltage loading between the anode and the cathode, and the heating value near the anode is reduced.
Example 3
At present, the application of electrolyzed water to oxygen production is mainly concentrated in the field of space stations and manned aerospace. The space station is in a weightlessness state, so that the electrolysis system is added with complicated parts such as gas-water separation, heat control and the like, and natural energy consumption and emission quality are increased.
This example was modified on the basis of example 1 to produce an electrolytic water oxygen plant capable of producing oxygen in a weightless environment, as shown in fig. 5.
An anode 2 is arranged on one side in the electrolytic tank 1, a cathode 5 is arranged on the other side, hydrogel 12 is filled between the anode 2 and the cathode 5, an auxiliary electrode 4 is inserted into the middle part of the hydrogel 12, an anode gas collecting space 9 is formed between the anode 2 and the side wall of the electrolytic tank 1, and an oxygen outlet 11 is arranged on the side wall of the electrolytic tank 1 on the side of the anode gas collecting space 9; a cathode gas collecting space 10 is formed between the cathode 5 and the side wall of the electrolytic cell, a hydrogen gas outlet 13 is arranged on the side wall of the electrolytic cell 1 at the side of the cathode gas collecting space 10, and a water supplementing port 14 is arranged at the contact wall of the electrolytic cell and the hydrogel 12.
When the device works, the technical process is similar to the application scheme. Here in particular: the electrolyte 3 of the above application scheme is replaced with hydrogel 12. Since the hydrogel 12 is a large amount of water which is adsorbed and restrained by the gel, the water does not float, overflow and spill in the weightless state, so that the anode 2, the cathode 5 and the water (electrolyte) in the hydrogel are in a stable state with each other, thereby ensuring the continuous electrolysis. In the electrolysis process, oxygen generated at the anode is collected in the anode gas collecting space 9 and then discharged through an oxygen outlet, hydrogen generated at the cathode is collected in the cathode gas collecting space 10 and then discharged through a hydrogen outlet 13, and clean water is introduced into a water supplementing port 14 to supplement water consumed by electrolysis.
The auxiliary electrode is woven by polytetrafluoroethylene insulated wires. The voltage peak applied between the auxiliary electrode and the anode is 1 to 4 kilovolts.
The electrolysis device of this embodiment can guarantee under weightlessness, violent rocking, upset condition that electrolysis process is effective continuously, and electrolysis process calorific capacity is little, and electrolysis power consumption is little.
Example 4
This example is directed to an electroplating system, and the structure of example 1 is shown in FIG. 6. It differs from example 1 in that the metal to be electroplated is taken as anode 2 and the workpiece to be electroplated is taken as cathode 5.
In operation of the apparatus, metal ions in the electrolyte, which serves as a plating solution, move from the anode 2 to the cathode of the workpiece being plated and deposit on the surface of the cathode 5 of the workpiece being plated. When the auxiliary electrode 4 is charged with a high voltage, the metal ions are driven by the electric field of the auxiliary electrode 4, stagnate near the auxiliary electrode 4, and only a small amount of the metal ions reach and adhere to the surface of the cathode 5 of the workpiece to be plated, at which time the plating layer is dense. When the auxiliary electrode 4 is charged with a low voltage or a negative voltage, the metal ions are driven by the electric field of the auxiliary electrode 4, rapidly leave the vicinity of the auxiliary electrode, and a large amount of metal ions reach and adhere to the cathode surface of the workpiece to be plated even in a pulse state, at which time the plating layer is loose. Thus, the state of the electroplated layer can be precisely controlled by loading the voltage of the auxiliary electrode, and the control can form multiple layers of different density layers on one electroplated surface, so that the precision can reach the nanometer level.
Multiple layers of electroplated layers of different densities offer more possibilities for the development of new materials and equipment.
The application of the device of this embodiment is as follows: firstly plating a compact layer on the surface of the metal substrate, then plating a loose layer, and then plating the compact layer on the final surface (the compact layer and the loose layer can be further alternately repeated for multiple layers, so that the plating layer is thickened). The thermal conductivity of the surface plating layer thus obtained is greatly reduced from that of the metal base material. When the coating structure is applied to the turbine blade of a high-power jet engine, the coating on the surface of the blade is in a semi-molten state under the high-temperature and high-pressure condition, and the surface of the blade contains loose coating, so that the thermal conductivity is low, and the blade substrate can still be effectively cooled and maintain the basic mechanical strength.
Example 5
This example was modified on the basis of example 4 with respect to the plating system, and its structure is shown in FIG. 7.
The anode 2 (metal to be electroplated) and the auxiliary electrode 4 are cylindrical in shape, the anode 2 is sleeved outside the auxiliary electrode 4, and the cathode 5 (workpiece to be electroplated) is located inside the auxiliary electrode 4.
It can be seen from the above examples that the present invention provides a new electrolysis apparatus comprising an auxiliary electrode insulated from the electrolysis (or electroplating) system, wherein the movement speed of ions in the electrolysis system can be regulated by applying a voltage to the auxiliary electrode, thereby reducing the heat generation in the vicinity of the electrode and thus reducing the energy consumption of the electrolysis process. The electrolytic device is applied to an electroplating system, and the speed of metal ions reaching a workpiece can be accurately regulated at low speed, so that multiple layers of electroplated layers with different densities can be prepared, and more possibilities are provided for developing new materials and equipment. Therefore, the invention has good application prospect.
