Description

Gas ion source device

The utility model relates to a kind of gas ion source apparatus that can produce ion stream in gas.

The application surface of gas ion source apparatus is very extensive, for example can be used for static elimination aspect, electric precipitation aspect, carries out the various aspects that intensive treatment or the like needs gas ion source to the adjusting aspect of air ion and to material surface.

In various equipment that need gas ion source such as present Xelminator, electric cleaner, anion generator and device, gas ion mainly relies on the corona discharge of sparking electrode or discharge corona wire directly to produce.

In ion stream Xelminator, its basic functional principle is: combine corona discharger by spray point electrode, electrode retaining collar (being battery lead plate with holes), after the spray point electrode applies high pressure, near the air generation ionization spray point electrode, air ion is just blowed away by the other compressed air of spray point electrode, produces the electric effect that disappears that neutralizes.Because the design of corona discharger has determined the electric usefulness that disappears to a great extent, if spray point electrode and electrode retaining collar distance are excessive, then the air ion of spray point electrode generation is few, and the electric current that disappears significantly reduces, and electric poor effect causes disappearing; If spray point electrode and electrode retaining collar distance is too small, then be easy to generate spark discharge between spray point electrode and the electrode retaining collar, cause in some places disappear the process of electricity, blasting, peril such as fire.Therefore, in ion stream Xelminator, be to regulate by the electrode resistance that is connected with electrode retaining collar, obviously, behind the adding electrode resistance, the electrical power of consumption can strengthen, thereby makes the decrease in efficiency of entire equipment, and this is a shortcoming.

In addition, in ion stream Xelminator, also need the supply air system that can produce certain blast, this has also strengthened the electric power consumption of equipment, and has increased production cost of products, and this is its another shortcoming.

In the electrostatic air anion generator, also be to have adopted and the similar operation principle of above-mentioned ion stream Xelminator.It is by adding negative high voltage on pointed electrode, produced a large amount of negative aeroions by the corona discharge of pointed electrode, be blown into the space of outside again by supply air system that obviously, this structure also has two shortcomings of above-mentioned ion stream Xelminator.

Conclude shortcomings such as existing gas ion source apparatus has poor safety performance, consumed power is big, ion generation efficient is low, cost height.

The purpose of this utility model is to provide a kind of ion to produce efficient height, safe and reliable, simple in structure, gas ion source apparatus that cost is low, and it can not need to set up supply air system.

The technical solution of the utility model is as follows: it is to be made of metal Jie plate (1), corona electrode (2), drive electrode (3) and high voltage source (4), wherein corona electrode (2) links to each other with high voltage source (4), drive electrode (3) but near ground connection and be placed on metal Jie plate (1), be enough to make metal Jie plate (1) to be activated the position of electrode (3) electrion effect, metal Jie plate (1) is placed on corona electrode (2) and connects within the corona zone (5) that high voltage source (4) back produced.Corona electrode wherein (2) can adopt ring-type or line corona silk, its number is more than one or one, and drive electrode (3) can adopt pointed electrode, and its number is more than one or one, metal Jie plate (1) be isolate, do not contact with other parts, and can support by insulator.The gas ion stream that utilizes the utility model to produce to have higher ionization level, two-forty.

The utility model also provides two embodiment of gas ion source apparatus.

A kind of is the gas ion source apparatus that can produce the pencil ion stream with consistent directionality, wherein metal Jie plate (1) is a kind of hollow cavity of ring-type, have annular notches one on the ring in it, ring-type corona electrode (2) can be placed in the hollow cavity of metal Jie plate (1), and pointed drive electrode (3) can be placed on the middle part of the interior ring of metal Jie plate (1).

Another kind is the gas ion source apparatus that can produce large-area gas ion stream, wherein metal Jie plate (1) be a kind ofly have "

" the strip frid of shape cross section, line corona electrode (2) can be placed in the middle along the be situated between length direction of plate (1) of metal, and pointed drive electrode (3) can be placed near the position in the face of the opening direction of metal Jie plate (1).

In the utility model, following condition is satisfied in the position of metal Jie plate (1): promptly under metal Jie plate (1) and the contacted situation of drive electrode (3), can not discharge or streamer-discahrge by flashing between metal Jie plate (1) and the corona electrode (2).Like this drive electrode (3) not with situation that electrode resistance links to each other under, also can make and the utlity model has higher safety performance, and the available power of whole device is increased.Satisfying under the above-mentioned locality condition of metal Jie plate (1) and corona electrode (2), improving the voltage on the corona electrode (2), can obtain the gas ion stream of higher rate, thereby not need supply air system.
