Abstract
The invention belongs to combustor safety assurance devices, more particularly relates to a full automatic safety pilot burner used in combustors. The pilot burner is characterized in that an oblique channel is arranged inside a three-way connecting block and connected with an injection cylinder, through holes are arranged on the lateral surface of the injection cylinder, and a gas nozzle is connected under the through holes of the injection cylinder; a wind adjusting cylinder is sheathed outside the lower part of the injection cylinder, gaps are arranged between the wind adjusting cylinder and the injection cylinder and communicated with the through holes, and a wind adjusting nut is arranged under the wind adjusting cylinder on the gas nozzle. A nozzle injector leads gas overflowing from the through holes to be limited in the gaps between the wind adjusting cylinder and the injection cylinder and quickly led back by negative pressure inside the injection cylinder, thus avoiding gas leakage and improving safety. An ionization flame checking electrode is adopted for avoiding that the unexpected extinguishing of the pilot burner is hard to be found in time and improving safety. The wind adjusting nut can be used for controlling the mixture ratio between combustion air and gas and improving applicability.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description:
As depicted in figs. 1 and 2, a kind of burner is used full-automatic altar lamp, comprises the ignitor 1 that links to each other with igniter, also comprises tedge 5.To be arranged side by side, flange 4 is provided with the hold-down screw 30 that is used for fixing ignitor 1 through flange 4 for ignitor 1 and tedge 5.The outside, upper end at ignitor 1 and tedge 5 is welded with stable flame cylinder 6, and the lower end of tedge 5 is provided with three-way connecting block 3, along tedge 5 ionization fire inspection electrode 2 is installed; The upper end of tedge 5 is provided with fuel burner nozzle 7; The upper end of fuel burner nozzle 7 is higher than the upper end of ignitor 1, and the upper end of fuel burner nozzle 7 is higher than the upper end of ignitor 1, has guaranteed that like this ignitor 1 is lower than altar lamp flame; Flame does not contact ignitor 1 during altar lamp work, has prolonged the service life of ignitor 1.Fuel burner nozzle 7 is provided with side opening 31.Stretch out from three-way connecting block 3 lower end of ionization fire inspection electrode 2, and stretch out from the upper end of fuel burner nozzle 7 upper end of ionization fire inspection electrode 2.
Like Fig. 1, Fig. 3 and shown in Figure 4, three-way connecting block 3 tiltedly below also be provided with nozzle injector 32, nozzle injector 32 comprises injection tube 8, locking nut 11, transfers air duct 10 and transfers conch female 12.In three-way connecting block 3, be provided with ramp way 14; This ramp way 14 is threaded with injection tube 8; Injection tube 8 sides have through hole 26, and the cross-sectional shape of injection tube 8 upper ends is circular, and the cross-sectional shape of injection tube 8 bottoms is a hexagon; The gas nozzle 13 that below the through hole 26 of injection tube 8, has been threaded is provided with locking nut 11 in gas nozzle 13 outer rings; Be with in the outside, the bottom of injection tube 8 and transfer air duct 10, transfer between air duct 10 and the injection tube 8 and be provided with slit 29, slit 29 communicates with through hole 26, be positioned on the gas nozzle 13 transfer air duct 10 below also be provided with accent conch mother 12.
Gas nozzle 13 ejection high-speed fuel gas jets of the present invention, thus the injection effect produced, the through hole 26 of air from injection tube 8 sucked and the combustion gas blending, formed the premix gas of combustion gas and air.From fuel burner nozzle 7 ejections, partly-premixed gas sprays from the side opening 31 of fuel burner nozzle 7 premix gas, directly contacts with ignitor 1 and is lighted through tedge 5.When ignitor 1 quit work, stable flame cylinder 6 played the effect of incendiary source, guaranteed the continual and steady of burning.Ionization fire inspection electrode 2 is assemblied in altar lamp head center position.When altar lamp was worked, ionization fire inspection electrode 2 was in flame central position, obtains flare up fire.
Concrete use of the present invention can be adopted the known technology of this area; As shown in Figure 5, provided a concrete embodiment, open the power switch 25 of explosion-proof control cabinet 19 during work; Power supply indicator 23 is bright; Open transformer switch 24 and button ignition switch 21 again, ignition transformer 18 is started working, and altar lamp assembly 14 begins igniting.Altar lamp ignitor 1 sparking 15 seconds, the magnetic valve 16 of gas pipeline 17 is opened simultaneously.After 15 seconds, igniter quits work, and 2 pairs of altar lamp flames of ionization fire inspection electrode detect; If altar lamp has flame, then ionization fire inspection electrode 2 produces flare up fire, passes to explosion-proof control cabinet 19 through cable; Magnetic valve 16 is kept out, and flame indicator lamp 22 green lights are bright.If the altar lamp fray-out of flame, then the flare up fire of ionization fire inspection electrode 2 disappears, and magnetic valve 16 will cut out automatically, prevent gas leakage, and flame indicator lamp 22 extinguishes with the indication of reporting to the police simultaneously.For further improving security performance, fray-out of flame signal of the present invention can be delivered between control through flare up fire transmission cable 20, and interior operating personnel's altar lamp fray-out of flame between notice control is so that in time handle.
Scope disclosed by the invention comprises disclosed technology and significantly replacement, can replace with quadrangle, pentagon structure etc. like the cross-sectional shape of bottom of the present invention.
