The specific embodiment
As shown in Fig. 1,2a, 2b, 3,4: the integrated altar lamp of a kind of intelligent ignition, comprise: float electrode, mounting sleeve 5, altar lamp shower nozzle 1, mixing section 2, gas nozzle 3, be provided with float electrode, altar lamp shower nozzle 1, mixing section 2, gas nozzle 3 in described mounting sleeve 5, described altar lamp shower nozzle 1 is connected with gas nozzle 3 by mixing section 2, gas nozzle 3 other ends are connected with fuel gas entrance 6 by pipeline, elbow, wherein, be provided with three volume seat airports 4 dividing equally on gas nozzle 3, volume seat airport 4 is communicated with igniting air intake 9; Described float electrode is connected to form by ignitor 10, propeller 8, and wherein, ignitor 10 is electrically connected to control cabinet by cable connector 7.
Described altar lamp shower nozzle 1 one sides are respectively arranged with stable flame hole 11 and equal discharge orifice 12.
Be provided with perforation 13 in described mounting sleeve 5.
Described propeller is the magnetic no-rod cylinder propeller.
Described float electrode, ignitor is being lighted altar lamp backed off after random flame region in other words, is positioned at all the time the low-temperature region of circulation of air, thereby keeps very long service life.Propeller adopts magnetic no-rod cylinder, and dustproof, volume is little, and the life-span is long, and it is convenient to take over.Only electrode need be advanced to the altar lamp head while again lighting a fire can light a fire again, and electrode length can be according to operating mode demand type selecting between 0.5-15m.
Described ignitor adopts the semiconductor electric discharge, and arc energy is high, and igniting is reliable, the high energy semiconductor igniter adopts low-voltage, large electric current, and by special semi-conducting material electric discharge, arc energy is high, and be not subject to medium influence, can in water, ice and pitch, normally put arc;
Described ignitor has a style of one's own, with exterior insulation, can be because electric leakage causes the not starting the arc, and supporting control instrument is disturbed little, be applicable to being applied to Automatic thermal Control system.
The integrated altar lamp of this intelligent ignition adapts to the large 0.02～0.25MPa of gaseous-pressure fluctuation range (gauge pressure), and can bear heating furnace and keep flame stabilization up to the draft of the negative pressure of-500Pa.
Its blowing system is independent, forms autonomous blowing system, is not subject to the impact of burner and heating furnace load change, even air blast or air-introduced machine break down, also can maintain normal ignition, is a reliable incendiary source of burner.Its principle is: high-pressure gas can play the effect of entrainmenting to surrounding air when Nozzle sprays at a high speed, form combustion gas-air mixture after the air that the appropriate design assurance is involved in and combustion gas mixing, the impact that this ratio is changed by gaseous-pressure hardly: gaseous-pressure is high, its volume seat effect is strong, and the air capacity of suction is large; Gaseous-pressure is low, and a little less than its volume seat effect, the air capacity of suction is little, thereby can keep more stable gas/air ratio.The altar lamp structural design of appropriate design can guarantee to form appropriate gas/air ratio, after the ejection of altar lamp shower nozzle, is easy to be lighted by electric spark, and ignition success rate is high.
This altar lamp is divided into two kinds of forms according to air supply mode,
