Structure using acid to generate electricity

The present invention is to provide a structure for generating electricity using acid liquid, especially a structure with simple structure, low material cost, recoverable waste acid liquid, and reducing acid strength of waste acid liquid to generate electricity.

According to the theory, the voltaic pile often talked about in theory is to use two different metal electrodes in contact with the electrolyte to generate a voltaic source. The original voltaic battery used silver and zinc metal electrodes, and there will be Corrosion of metal electrodes is lost to produce electrical energy. The structure of the battery needs to be continuously improved with the times, such as lead-acid batteries, dry batteries, mercury batteries, and now commonly used lithium batteries, etc., but these batteries need to use the corrosion loss of the electrode and the reaction using the electrolyte, not only the material acquisition cost is higher , And all are the loss of limited earth resources, and cause environmental pollution in exchange for electrical energy.

Fruit battery is a technology that uses the redox reaction of fruit to generate potential difference to generate electricity. Generally speaking, fruits are rich in vitamin C and appear acidic. The principle of the fruit battery is to use the hydrogen ions of the acidic substances in the juice to be reduced to hydrogen gas at the positive electrode (the standard electrode potential of hydrogen is 0.00V), and the zinc of the negative electrode Easily oxidized (standard oxidation potential of zinc is 0.74V). Therefore, when the copper sheet is used as the positive electrode and the zinc sheet is used as the negative electrode, the potential difference generated is 0.74V. However, the current of the fruit battery is too small, usually only a few microamperes, and the electrolyte and tissue state in the fruit cannot make the transmission of ions and electrons work under high current operation. In addition, the fruit with higher safety In addition to the small current, the main disadvantage of the battery is that the hydrogen produced by the negative electrode will still accumulate on the surface of the electrode, and the metal of the positive electrode will be corroded by hydrogen ions. Therefore, the fruit tissue cannot effectively eliminate the problem of hydrogen and metal corrosion. , Will affect the battery's long-term performance and cause potential danger.

Therefore, when using the above battery, the following problems and deficiencies still need to be improved:

First, the cost of materials is high, and they are all expendable batteries. Whether they consume electrolytes, catalysts, or other earth resources, they are not enough to be called environmentally friendly batteries.

Second, the current of the fruit battery is too small to be practically used, and the hydrogen generated by the negative electrode is not properly excluded from the pipeline, and the metal of the positive electrode is also susceptible to acid corrosion, which affects the power generation effect.

Therefore, how to solve the above-mentioned problems and deficiencies in practice is the one where the creators of this new type and related manufacturers engaged in this industry are desperate to study the direction of improvement.

Therefore, in view of the above-mentioned deficiencies, the creator of this new model has collected relevant data, evaluated and considered through multiple parties, and based on years of experience accumulated in this industry, through continuous trial work and modification, he has designed such a simple structure and material cost.

Using the principle that the acidic liquid will spontaneously react to the metal, the metal parts are immersed in the waste acidic liquid to generate electricity. Among them, the recovery of the waste acidic liquid is a low-cost material, and the positive electrode of the power supply is chemically inactive graphite After the reaction, the hydrogen ions in the waste acidic liquid become hydrogen and disperse in the air. The metal elements of the metal parts are dissolved in the waste acidic liquid. Therefore, it does not corrode the graphite parts of the power supply positive electrode, and can also reduce The acid strength of the waste acid liquid has a long service life, which is beneficial to reduce environmental pollution, and the whole is modularized by the containing tank, and the current and voltage strength can be adjusted freely, which is very convenient to use.

Through the above description, the structure of this technology can be understood, and according to the corresponding coordination of this structure, it can achieve advantages such as simple structure, low material cost, recyclable waste acid liquid 2, and reduced acid strength of waste acid liquid 2. And the detailed explanation will be explained below.

Please also refer to the first picture to the third picture, which are the perspective view to the use state diagram of the preferred embodiment of the new model. When the above components are configured, it can be clearly seen from the figure that the new model uses acid The principle that the liquid will react to the metal spontaneously. Immerse the metal part 4 in the waste acidic liquid 2 to generate electricity, and connect one end of the power output component 5 to the graphite part 3 and the metal part 4, and the other end to the power storage device 6. It can be charged. Taking the metal part 4 as zinc as an example, the reaction formula is:

The positive electrode ^{reaction: 2H + (aq) + 2e} - → H 2 (g) E = 0.00V

Negative electrode reaction: Zn(s)→Zn ²⁺ (aq)+2e ^- E=+0.74V

Total reaction: Zn(s)+2H ⁺ (aq)→Zn ²⁺ (aq)+H ₂ (g) E=+0.74V, where H ⁺ (aq) is hydrogen ion solution, H ₂ (g) is hydrogen, Zn(s) is solid zinc and Zn ²⁺ (aq) is zinc ion solution.

The waste acid liquid 2 of the new type is recovered from waste acid, waste water, or acid rain, and is a liquid that is not practical and even harmful to the environment. Therefore, the recovery of waste acid liquid 2 is a low cost The material, the part of the metal part 4, according to the hydrogen ion of the above reaction formula, the selection condition is only that the standard electrode potential is less than 0, for example, the standard electrode potential of ferrous iron is -0.441V, the standard electrode potential of nickel is -0.250V, two The standard electrode potential of valence chromium is -0.56V, the standard electrode potential of trivalent chromium is -0.74V, etc. are commonly used metals, so scrap metal containing iron, zinc, nickel, chromium and other metal materials can be recycled as this new The use of metal parts 4 can further reduce the overall material cost.

In addition, the power output component 5 can be connected and fixed to the graphite member 3 and the metal member 4, respectively, or can be coupled to the metal through a conductive medium 51 (such as a metal plate or graphite plate) provided in the accommodating groove 1 4, and in this embodiment, the conductive medium 51 is connected to the outside by way of the receiving groove 1, and at least one sealing portion 52 (such as waterproof glue) is provided between the conductive medium 51 and the receiving groove 1, In order to avoid the leakage of the waste acid liquid 2 and the power output unit 5 from being affected by the waste acid liquid 2.

In addition, the material characteristics of graphite itself include strong corrosion resistance, so it can be placed in waste acidic liquid 2 for a long time without corrosion. The material characteristics of graphite itself also include chemical inactivity, making graphite 3 as When the positive electrode of the power supply is used, there is almost no need to replace it, and it does not affect the reaction effect. Similarly, when the hydrogen ion reacts at the positive electrode of the power supply where the graphite member 3 is located, it also directly reacts as gaseous hydrogen in the air and does not adhere to the graphite. The surface of the piece 3 further reduces the concentration of hydrogen ions in the waste acid liquid 2, which means that the acid strength of the waste acid liquid 2 can be reduced, and the metal element generated after the reaction of the metal piece 4 is dissolved in the waste acid liquid 2, due to the waste The acidic liquid 2 will be transferred to the sewage treatment plant, etc., so even if the metal element that is not originally added is added, it will not cause an impact.

Assuming that the reaction current generated by a single graphite piece 3a is 0.3A, as long as ten graphite pieces 3a are connected in series with each other, a current of 3A can be generated, and the reaction voltage generated by a single accommodating tank 1a is 0.74V, as long as the series four Each accommodating tank 1a can generate a voltage close to 3V. In addition, a single metal part 4a can maintain a reaction time of 60 minutes. As long as three metal parts 4a are placed at the same time, it can be maintained for 180 minutes. In this way, as long as the power output unit 5a is directly connected to a power consumption device 7a that can be supplied and operated by a general battery, the waste acidic liquid 2a can be used to directly generate power and supplied to the power consumption device 7a for operation.

Please also refer to the fifth figure at the same time, which is a perspective view of another preferred embodiment of the present invention. It can be clearly seen from the figure that this embodiment is similar to the above embodiment, only on the side of the conductive medium 51b A coupling portion 53b extending outside the waste acidic liquid 2b is provided so that the power output module 5b can complete the power output without contacting the waste acidic liquid 2b in a manner that does not damage the accommodating tank 1b. In this embodiment, the conductive medium 51b is exemplified by an L-shaped configuration, and the coupling portion 53b is an L-shaped vertical edge, or the bottom edge of the conductive medium 51b can be further changed into a whole piece, and the tile is fully covered The groove 1b increases the contact area with the metal piece 4b, thereby explaining the variability of the new power output method of the present invention.

However, the above is only the preferred embodiment of the new model, otherwise the new model is limited The scope of the patent of the type, therefore, any simple modification and equivalent structural change caused by the use of the description and drawings of the new model should be included in the patent scope of the new model in the same way, and it should be Chen Ming.

First, both the electrolyte and the negative electrode of the power supply can use low-cost recycled materials, so the use cost can be greatly reduced.

Second, the positive pole of the power supply uses graphite 3, so it can use its inertness and corrosion resistance to effectively improve the stability of power generation and the service life of the new model.

Third, when the waste acid is used as the electrolyte, the acid strength of the waste acid liquid 2 can be further reduced after the reaction, thereby reducing environmental pollution or shortening the working hours of sewage treatment.

Fourthly, by increasing or decreasing the number of graphite parts 3, accommodating tanks 1 and metal parts 4, the reaction current, the reaction voltage and the reaction maintenance time can be freely controlled for use in different situations, and the degree of freedom of use is high.
