Description
Technical field
The present invention relates to employed electrostatic atomiser in the system that needs atomizing of liquids arbitrarily.The system that for example, can be used for fuel service system, the solution that transmits medicine, injection family expenses skin lotion and other synthetic solvents.The application is defined in these special applications, and it can be used for any nozzle in the application's claim protection domain.
Background technology
The present invention is by using and reaching the pulverability that the diverse method of prior art described herein is improved electrostatic atomiser known to the applicant.
General nozzle of the prior art comprises a central electrode, one external electrode around the line electrode in above-mentioned, and they have enough distances to form a passage each other, and fluid particles this passage of flowing through is gone out from outlet then.In this structure, usually central electrode is high potential and external electrode ground connection.It is unpractical that these voltages are just led to high voltage on the external electrode conversely, because in this case, if the operator has unexpectedly touched external electrode the danger of being electrocuted is so just arranged, perhaps need to use for example ceramic package of additional insulating barrier, the unnecessary complexity that this just increases.Therefore, prior art system all is with high potential backbone electrode rather than external electrode.
Fig. 1 has represented some constraintss in the time of the nozzle operation of prior art.Spraying is a kind of balance between ceiling voltage, the percentage of discharging voltage residual in the liquid and electrode spacing (distance between the electrode).In prior art system, along with electrode spacing increases, ceiling voltage also increases, but residual critical voltage has but reduced in getting rid of liquid, so just causes the spraying deterioration above the given electrode spacing of specific nozzle.
One object of the present invention just provides a kind of diverse nozzle, and it can eliminate design limitation very harsh in the prior art systems to greatest extent.
In content of the present invention, relate to a lot of special systems of the prior art, will describe in detail below.
A kind of prior art is to use single central electrode in spraying system, and a cusp place stops on its liquid surface, just can produce very high electric field at this point like this.U.S. Pat 6,206,307 (Arnold J Kelly) disclose such system, and one of them electrode is cone tip shape and is inserted in the fluid of flowing through.The disclosed awl point that is described in detail to of this patent is made with fibrous material, and conductive fiber extends axially along electrode and body, and each such fiber all has a small point, and these points have constituted the surface of awl point together.The surface of outlet is without any fiber, and is and preferably smooth.The common end of this special nozzle has a point, can accurately aim at outlet 22.Therefore, in its manufacture process, just need point-device concentric tolerance.And, for various reasons, can't avoid in the use of nozzle, awl point and outlet to changing.
It is top that another piece U.S. Pat 4,627,903 (Alan T Chapman) discloses another kind of fiber, and its cusp at electrode uses composite sheet, and this composite sheet is included in evenly distributed ultra micro metallic fiber in non-conductive (insulation) matrix.
It is bell (having circular edge) that another kind of prior art systems discloses electrode tip.This structure normally is used to have the nozzle of circumferential outlet.The accompanying drawing 2 that has the paper that this example of structure can deliver in July, 1998 referring to A.J.Kelly in DOE (diesel engine emissions factory).Another example of electrode discloses among 151 (the Robert Hetrick) at US 5,725 like this.
Each so bell electrode is with all exigent concentric tolerance of above-mentioned conical electrode.
The all exigent tolerance of above-mentioned every kind of structure of the prior art and very accurate electrode tip shape will be arranged according to export structure.
An object of the present invention is to provide a kind of nozzle, its electrode shape can be widely used in various export structures.Therefore the present invention is desirable to provide a kind of more flexible system, and tolerance and top shape are not had strict especially requirement.
Another target of the present invention provides a kind of nozzle, and its design and manufacturing all have the very high free degree, is fit to very much produce in batches.
Another target of the present invention provides a kind of nozzle, still is single outlet nozzle for the multiple exit nozzle no matter, and its pulverability all increases.
Summary of the invention
According to a first aspect of the invention, the present invention relates to a kind of electrostatic atomiser, it comprises a pipeline, when in use, and liquid this pipeline of flowing through; One or more outlets can make the liquid mass flowing nozzle; At least two in the time of nozzle operation and the liquid electrodes in contact, when a suitable voltage was fed into above-mentioned electrode, liquid particle just was discharged away like this; It is characterized in that in the above-mentioned electrode at least one has a liquid contact region territory, this zone comprises the compact arranged non-fiber conducting element of a row, they, just can be concentrated at the electric field that the electrode points nozzle is produced so that form the independent electrode points of a row basically from the electrode upper process.
The advantage of this structure is that it can save complicated requirement that is too complicated, that electrode tip will be alignd with specific outlet.And the jet rose of this structure can have the very end of long radius, rather than resembles that electrode tip all is the sharp edges that cusp is maybe had when having bell-shaped end the prior art.This structure can also obtain spraying uniformly in its exit.Its manufacturing is compared also with above-mentioned prior art system and has been simplified greatly.
