Description
Technical field
The invention belongs to the liquid super-fine atomization technology.Be specifically related to a kind of device that utilizes high-pressure electrostatic to realize liquid super-fine atomization.
Background technology
High-pressure electrostatic help the atomization of liquid and spray insecticide at electrostatic precipitation, electrostatic painting, static, field such as electrostatic dusting, the manufacturing of electrostatic atomization emulsion obtained extensive use.Electrostatic greasing device (ZL98232316.6) is exactly the oiling problem that preferably resolves steel plate, but also exists following problem in application: the holiday phenomenon is arranged in 1, the oiling process, only seriously influenced the quality of oiling; 2, mist droplet particle size is bigger in the oiling, and atomizing effect is poor; 3, oil atomization voltage is higher, and energy consumption is higher; 4,, make the cost of oiling station be difficult to reduce because oil spout uses the cutter beam to the processing request height.
Summary of the invention
The object of the invention provides that a kind of cost is low, atomizing effect good, energy consumption is low, can realize the device that multiple liquid atomizes under high-pressure electrostatic.This device can be applicable to the multiple occasion that needs the granule drop, and for example: high pressure electrostatic painting, the engine fuel atomizing is combustion-supporting.
For achieving the above object, the technical solution used in the present invention is: negative high-voltage generator connects with metal drum by high-tension cable, the suction side of measuring pump communicates with the bottom of liquid reserve tank by a transfusion catheter, an end of another root transfusion catheter and the top that the sucking-off end of measuring pump connects, its other end is arranged on metal drum; The bottom of metal drum is fixed with the needle-like nozzle, and the centre bore of needle-like nozzle communicates with the bottom of metal 3, ring-type filament secondary-atomizing electrode is housed below the needle-like nozzle, and ring-type filament secondary-atomizing electrode passes through resistance eutral grounding; The below of ring-type filament secondary-atomizing electrode is an earthing pole.Wherein:
The distance h of needle-like nozzle and ring-type filament secondary-atomizing electrode is 150～500mm, and the distance H of needle-like nozzle and earthing pole is 500～1000mm; The circle diameter D of ring-type filament secondary-atomizing electrode is 100～300mm, and the metal material cross-sectional diameter d that ring-type filament secondary-atomizing electrode is selected for use is 10～15mm.
Owing to adopt technique scheme, can be implemented in the atomizing of multiple liquid under certain negative high voltage, the needle-like nozzle can not only make the atomization of liquid, and less because of the nozzle form radius of curvature, can also reduce discharge inception voltage, energy consumption reduction; For electrostatic oiler, because the high cutter beam of the nozzle substituted processing request of needle-like, thereby can significantly reduce cost.
In the present invention, negative high-voltage generator can produce 10000 volts to 100000 volts negative high voltage, is connected with metal drum by high-tension cable, and the liquid in the metal drum is by charged with the metal drum contact that is connected high voltage source.Liquid after charged flows out through the needle-like nozzle, and the needle-like of nozzle produces the corona discharge phenomenon, can make drop charged once more.
The drop of a large amount of negative electrical charges of the same race has been gathered on the surface, and to the earthing pole motion, after the electrostatic repulsion of like charges on the drop surface surpassed the drip gauge surface tension, drop promptly produced atomizating phenomenon under the effect of electric field force and gravity.After drop passes through the secondary-atomizing electrode retaining collar, will produce the secondary-atomizing phenomenon.Form the primary atomization field between needle-like nozzle and the ring-type filament secondary-atomizing electrode, form the secondary-atomizing field between ring-type filament secondary-atomizing electrode and the earthing pole.This electrode significantly reduces the atomizing particle size under liquid the same terms of the same race, improves atomizing effect, and is better than the atomizing effect of traditional high-speed jet or high speed rotation and patented technology realization.For example: with 93# gasoline is that example experimentizes, and atomizing voltage is 50KV, and the atomized drop particle diameter that does not add secondary-atomizing electrode gained is 50um, add the secondary-atomizing electrode after, particle diameter can be reduced to 10um following (particle size values adopts laser particle analyzer to measure).
Therefore, this device can be realized the atomizing of multiple liquid under high-pressure electrostatic, has that cost is low, atomizing effect good, characteristic of low energy consumption.Can be widely used in high pressure electrostatic painting or the engine fuel atomizing multiple occasion that needs the granule drop such as combustion-supporting.
