3, negative electrode is led cap upper edge circumferential edges and is evenly offered spacer.
Advantage of the present invention is: the invention solves ignition burner under the high voltage operation state, reliably insulate and the problem of stable diesel oil atomization, and because the fuel supply mode is special, make improve greatly the service life of generator.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the object of the invention and technical problem solution adopt following technical scheme to realize.A kind of High-Voltage Insulation diesel oil atomization ignition burner according to the present invention proposes is characterized in that it by mount pad, insulator, and the cathode insulation pottery, negative electrode is led cap, compositions such as backstay, cyclone and nozzle.Its technical characterstic is the special construction through insulating ceramics, and diesel oil is introduced negative electrode, produces atomizing effect through cyclone and nozzle; Insulating ceramics can be realized high-tension insulation simultaneously, guarantees the igniting reliably working, and since ceramic, can under the condition of high temperature, continue to work reliably; Because the diesel oil supply pressure is high, the contact-making surface of insulating ceramics and mount pad all is provided with graphite gasket and seals.
The present invention adopts above technical scheme to can be implemented under the high-tension igniton duty, and reliably insulation, diesel oil atomization spray and well do not reveal between ignitor.
The present invention includes ceramic mount pad 3, graphite grazing pad 2, cathode insulation pottery 5, negative electrode is led cap 1, backstay 4, integrated cyclone-nozzle-anode 6, compressor arm 7.
Mount pad 3 top connections are provided with hickey and link to each other with high-voltage ignition cable, and negative electrode is led cap 1, backstay 4, cyclone, nozzle and negative electrode 6 through screw thread and insulating ceramics 5 close proximity, and mount pad 3 is connected through screw rod with anode and communicates with the earth.
Cathode insulation pottery 5 adopts the high-temperature insulation ceramic material, and mount pad 3 and the reliable insulated separation of negative electrode are opened to avoid the short circuit sparking, can the 30KV of anti-the DC voltage according to the present embodiment design.
Cathode insulation pottery 5 sides offer pod apertures, and the diesel oil of being imported by mount pad 3 interfaces injects negative electrode inside thus.
Negative electrode is led cap 1 upper edge circumferential edges and is evenly offered spacer, can after 5 tight connections the spacer bending prevented the screw thread slippage with the cathode insulation pottery.
Symmetry offers 45 ° inclination eddy flow groove on the cyclone, can make diesel oil under high pressure, produce rotation at a high speed.Nozzle and cyclone are combined closely, and the nozzle bottom center offers small spray orifice, and be corresponding with the eddy flow groove center, rotates diesel oil spray orifice ejection generation atomizing thus at a high speed.
Negative electrode adopts 45 ° of opening designs, and is consistent with the nozzle atomization angle.
The form assembling axisymmetricly of negative electrode and anode produces electric spark and lights atomized diesel fuel in the middle of the two annular gap.
