Description

Filter structure for reducing liquid conductivity and hydrogen production device thereof and filtration method using the same

The present invention relates to a filter structure, and more particularly to a filter structure capable of reducing liquid conductivity, and to a hydrogen production facility and a filtration method using the same.

According to the academic literature, hydrogen has been applied to humans, animals, plants and the like to have a considerable degree of health care or curative effect, and the research of hydrogen applied to medicine has flourished. In recent years, it has been found that hydrogen and hydrogen water not only have health effects for human health, but also have significant effects on agriculture or even aquaculture.

There are many ways to produce hydrogen, but the small amount of hydrogen production technology applied in hydrogen health care can be roughly divided into three types: 1. In the hydrogen production mode of magnesium metal, metal magnesium rod or magnesium powder is in contact with water. Hydrogen is produced by chemical reaction, but the hydrogen produced is low in purity and easily accumulates excessive magnesium in the human body, causing problems such as physical burden or injury; 2. In the traditional water electrolysis method, as shown in Figure 1. It is shown that the conventional electrolysis device (F) uses liquid electrolyte to electrolyze water to generate hydrogen gas, but in this way, since the water body which is a hydrogen-producing raw material needs to have a good conductivity, the electrolysis efficiency can be improved, so The raw material water used (as shown in the figure is tap water) is generally a relatively pure, highly conductive water that is sent directly to the electrolysis equipment; however, the metal ions in the liquid electrolyte used are easier to electrolyze. The medium is brought to the hydrogen end, causing it to have the liquid electrolyte to pollute the hydrogen. If it is used for a long time, the damage to the health will be difficult to evaluate. 3. The hydrogen production method of the proton exchange membrane: use Proton Exchange Membrane (PEM) electrolysis, which produces the purity of hydrogen required to meet the recommendations of the Food and Drug Administration (FDA) for hydrogen as a food additive, ie Purity needs to be greater than 99.995%, and because it uses solid electrolytes, it also avoids the doubt that hydrogen is easily caused by traditional electrolysis. However, this method is not only costly, but also has a high technical threshold. There are not many products that are applied to the technology and applied to the product.

Furthermore, since pure water cannot conduct electricity, various ions are required to dissolve in water to help conduct electricity, but this is accompanied by many harmful by-products, such as conventional electrolyzed water, which produce chlorine by-products due to chloride ions in the water. Harm to the body. The proton exchange membrane hydrogen production method uses a high-molecular proton exchange membrane as a solid electrolyte, and does not require liquid ions in water. On the contrary, the higher the purity of the water, the better, the protection of the core battery, and thus the super high Purity of hydrogen without accompanying other by-products. High-purity hydrogen can be obtained by proton exchange membrane electrolysis hydrogen production, but the purity of the raw material water used for the proton exchange membrane needs to be quite high. Basically, the conductivity is required to be < 1~2 uS/cm, which is already pure water grade. . This is because the proton exchange membrane hydrogen production module has a key component: the proton exchange membrane, which uses a carbon material as the substrate, and then coats the precious metal catalyst (generally platinum (Pt)-based). On the other hand, the noble metal catalyst is relatively easy to bond with the metal anion and cation in the pure water of the raw material, thereby deteriorating or even poisoning the catalytic performance.

However, the pure water required for the proton exchange membrane hydrogen production module is not only difficult to obtain, but also expensive, and since the pure water is exposed to the air, the carbon dioxide (CO2) in the air is rapidly dissolved into the pure water, resulting in its The conductivity rises rapidly, so it is relatively difficult to store pure water. Therefore, how to develop a filter structure for reducing liquid conductivity and a hydrogen production device thereof and a filtration method using the same, can reduce the conductivity of the water body after filtering the water body, and provide the proton exchange membrane hydrogen production module after the filtered water body The use of this, in order to produce a large amount of high-purity hydrogen, hydrogen water, is the subject of active research and development by various industry players.
