Described carboxylic acid compound is citric acid or acetic acid.
The negative high voltage of described anion generator discharges most advanced and sophisticated and the ground connection tip axially arranges with one heart along metal tube.
Described output precision is air blast class air-supply arrangement.
Described output precision is micropore ultrasonic atomizatio assembly.
According to claim 1, the method for generation of small particle diameter anion comprise following concrete steps:
(1) anion generator is converted to input current negative direct current high voltage, is connected to negative high voltage release tip, and the negative high voltage that arranges in pairs discharges tip and the ground connection tip produces high corona, discharges a large amount of electronics e-;
(2) electronics e-is caught, produces negative aeroion by the air in metal tube, and metal pipe internal surface and negative aeroion react, make its outer surface to produce negative electric field;
(3) negative electric field of outer surface of metal pipe makes the carboxyl hydrogen atom dehydrogenation of the carboxylic acid compound in the aqueous solution of carboxylic acid compound and makes the hydrogen cation of deviating from load negative electrical charge, thereby generates the hydride ion of small particle diameter;
(4) the output precision hydride ion that will overflow the small particle diameter of the aqueous solution is delivered in external environment.
In described step (1), the negative high voltage that can only insert anion generator in metal tube discharges tip, does not insert the ground connection tip, and during anion generator work, negative high voltage discharges most advanced and sophisticated a large amount of electronics e-that can work alone, discharge.
The beneficial effect that the present invention brings is:
Adopt generating means and the method for generation thereof of small particle diameter anion of the present invention, the small particle diameter anion that produces is active by force, migration distance is far away, the adsorption particle ability is strong, the sterilization performance is good, to the good purification of air, can not produce simultaneously the material that is detrimental to health, thoroughly stop ozone and occur, can not produce electrostatic interference yet.The generating means of small particle diameter anion of the present invention is the present anion air-cleaning facility of first item take hydride ion as medium in the world, it is simple in structure, can make the micro device that is beneficial to portable mobile, and only improve a little on the basis of existing commercially available anion generator just can make, with low cost, can with any miscellaneous equipment (as air-conditioning, refrigerator, fan etc.) grafting, and operate simple and easy, easy to use, reliable and secure, be beneficial to and use on a large scale and promote.

Theory and practice all proves, the small particle diameter anion also is light ion or small ion, is a kind of negative aeroion (also being called the ecological anion) that is equal to the Nature, has migration distance high characteristics far away, active.Therefore, the small particle diameter anion is not that the Dan Zhiqi particle diameter is little, and the small particle diameter anion defines according to migration distance, and migration distance far is only the definition standard of small particle diameter anion.
The radius of oxygen atom is 0.074 nanometer, in the situation that do not consider the atom bonding gap, the diameter of an oxygen molecule is 0.3 nanometer left and right (0.346 nanometer); And the hydrogen atom radius is 0.1 nanometer, and the diameter of a hydrogen molecule is 0.289 nanometer; The diameter of hydrone is about 0.4 nanometer.
Therefore, after having carried out long-term further investigation and experimental evaluation, the present invention selects hydrogen molecule or the hydrogen ion carrier as the small particle diameter anion.
Below further analyze the operation principle of apparatus of the present invention:
Carboxylic acids organic acid itself under field conditions (factors), just has the ionization of generation dehydrogenation reaction, thereby shows certain acidity, after obtaining certain electric field energy, can further strengthen the desorption process of hydrogen.We know, the molecular acid formula is C2H4O2 (CH3COOH),, because acetic acid is the main component of vinegar, claims again acetic acid, and itself has bactericidal effect.The saturated carboxylic acid that contains two carbon atoms in molecular acid, be the important containing oxygen derivative of hydrocarbon, and functional group is carboxyl, and the carboxyl hydrogen atom of acetic acid can partial ionization become hydrogen ion (or proton) and discharge.Add acetic acid (material with carboxyl structure) in water, make hydrogen ion easily break away from.
In like manner, citric acid (molecular formula C6H8O7) is a kind of stronger organic acid, and 3 hydrogen cation H are arranged
+Can ionize, the citric acid colorless and odorless, be safe food additives, easily buys.
In apparatus of the present invention, at 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 the most advanced and sophisticated 5(earth terminal of ground connection carbon nano-fiber bundle), to metal tube 2(stainless steel tube) interior atmospherical discharges makes its ionization.Due to metal tube 2(stainless steel tube) two-port is water-tight, therefore is not subjected to external environment influence fully, work very reliable and stable.At metal tube 2(stainless steel tube) manage under the effect of inner high voltage discharge, metal tube 2(stainless steel tube) exterior face gathers has suitable negative electric field energy and passes to acetic acid aqueous solution in water container 1, accelerates carboxyl hydrogen atom ionization in acetic acid and becomes hydrionic certain embodiments.Simultaneously, in hydrogen ion discharged the process of escaping further combined with one-tenth hydrogen, negative electric field was to negative electrical charge on its lotus, and the water smoke that is attached to 6 atomizations of micropore ultrasonic atomizatio assembly outwards is discharged into and needs in better purifying space, or by outwards release of air-supply arrangement (as fan 7).Due to, hydrogen has extremely strong penetrability and relative oxygen has less particle diameter, and the anion that therefore than traditional method, produces has stronger activity.
Be attached to the water smoke molecule airborne hydrogen that permeates, may be with electronegative hydrogen molecule H
2 -, hydride ion H
-, hydrogen cation H
+Variform coexists, and, also there is hydride ion H in the mechanism that purifies air except aforementioned routine
-, hydrogen cation H
+Cluster ion and airborne germ bump, and virus is surrounded, and at virus surface, react and make its deactivation.
