Theory and practice all proves, small particle diameter anion is also light ion or small ion, is a kind of negative aeroion (being also called ecological anion) being equal to the Nature, has migration distance high feature far away, active.Therefore, small particle diameter anion is not that Dan Zhiqi particle diameter is little, and small particle diameter anion defines according to migration distance, and migration distance is far only the definition standard of small particle diameter anion.
The radius of oxygen atom is 0.074 nanometer, and when not considering atom bonding gap, the diameter of an oxygen molecule is 0.3 ran (0.346 nanometer); And hydrogen atom radius is 0.1 nanometer, the diameter of a hydrogen molecule is 0.289 nanometer; The diameter of hydrone is then about 0.4 nanometer.
Therefore, after having carried out long-term further investigation and experimental evaluation, the present invention has selected hydrogen molecule or hydrogen ion as the carrier of small particle diameter anion.
Analyze the operation principle of apparatus of the present invention below further:
Carboxylic acids organic acid itself under field conditions (factors), just has and ionization dehydrogenation reaction occurs, thus show certain acidity, after obtaining certain electric field energy, can further enhance the desorption process of hydrogen.We know, molecular acid formula is C2H4O2 (CH3COOH), because acetic acid is the main component of vinegar, also known as acetic acid, itself has bactericidal effect.Saturated carboxylic acid containing two carbon atoms in molecular acid, be the important containing oxygen derivative of hydrocarbon, functional group is carboxyl, and the carboxyl hydrogen atom of acetic acid partial ionization can become hydrogen ion (or proton) and discharge.In water, add acetic acid (there is the material of carboxyl structure), hydrogen ion is easily departed from.
In like manner, citric acid (molecular formula C6H8O7) is a kind of stronger organic acid, has 3 hydrogen cation H
+can ionize, citric acid colorless and odorless, be safe food additives, easily buy.
In apparatus of the present invention, first, based on metal tube 2(stainless steel tube in water container 1) in be located at two-port encapsulation anion generator 3 negative high voltage discharge most advanced and sophisticated 4(high-pressure anionic transmitting terminal) and ground connection tip 5(earth terminal carbon nanofiber bundle), to metal tube 2(stainless steel tube) in atmospherical discharges make it ionize.Due to metal tube 2(stainless steel tube) two-port is water-tight, therefore completely not by external environment influence, works very reliable and stable.At metal tube 2(stainless steel tube) pipe inner high voltage electric discharge effect under, metal tube 2(stainless steel tube) exterior face gathers has suitable negative electric field energy and the acetic acid aqueous solution passed in water container 1, and accelerate carboxyl hydrogen atom ionization in acetic acid and become hydrionic certain embodiments.Meanwhile, at hydrogen ion further combined with in the process becoming hydrogen release to escape, negative electric field is to negative electrical charge on its lotus, and the water smoke being attached to the atomization of micropore ultrasonic atomizatio assembly 6 is outwards discharged into and needs in better purifying space, or is outwards discharged by air-supply arrangement (as fan 7).Due to, hydrogen has extremely strong penetrability and relative oxygen has less particle diameter, and the anion therefore produced than traditional method has stronger activity.
Be attached to the hydrogen that water smoke molecule permeates in air, may with electronegative hydrogen molecule H
