Ginseng Fig. 1 or shown in Figure 2, premixed dual-segment fire energy-saving combustion engine showerhead 100 of the present invention mainly includes as the lower part:
(1) is arranged on the shower nozzle wall 200 of shower nozzle periphery.
In the present invention, the shower nozzle wall 200 that is adopted must adopt refractory material to make.Preferred embodiment is fire-resistant metal material, comprises alloy material, and its machine-shaping etc. is all compared convenient; Secondly, can also adopt refractory ceramic material to realize.
(2) surrounded by shower nozzle wall 200, comprise just mixed chamber 810, be gathering chamber 820 of drawing structure in and the premix chamber 800 that is the expansion cavity 830 of expansion structure with respect to gathering chamber 820 with respect to the aperture of just mixing the chamber.
Premix chamber 800 purpose is set, be for the combustion gas of air and big fire section can fully be mixed before burning, thereby reach abundant burning, reduce the purpose of waste gas, energy savings.In the present invention, in order to realize the premix purpose better, this premix chamber 800 has been divided into three parts.
First mixed chamber 810 wherein is to be used to the cavity part that realizes that the combustion gas of big fire section mixed with the air initial stage of carrying out.Big fire section combustion gas wherein comes from big fire section gas nozzle 610; Air comes from the gas outlet on the premix dish 300.Corresponding opposite side at premix dish 300 can be provided with structures such as air blast.In the present invention, just mixing chamber 810 is empty column structures.
Gathering chamber 820 wherein is the cavity parts of dwindling with respect to the aperture of just mixing chamber 810.Shown in the ginseng figure, drawing chamber 820 parts in, the aperture is significantly contraction-like with respect to the aperture size of just mixing chamber 810.The effect of She Zhiing is like this: combustion gas and Air mixing gas can be realized the immixture of pressurizeing herein.
The outside drawing chamber 820 in is provided with expansion cavity 830.The aperture of expansion cavity 830 is progressively expansion structure with respect to drawing chamber 820 in.The effect of She Zhiing is like this: combustion gas and Air mixing gas, and after gathering chamber 820 is pressurizeed, concentrated, in expansion cavity 830, can discharge rapidly, expand, thus the mixability of the air that can accelerate significantly and combustion gas.
(3) be arranged on just mixed chamber 810 opening parts, have the premix dish 300 of air inlet 310.
Described premix dish 300 is and the corresponding disk-like structure of combustion gas fan interface case.The air inlet 310 that is provided with on premix dish 300 can import to the wind that blower fan roused just and mix in the chamber 810.Further, in order to add the mixed effect of strong wind, can between the axis with the passage of air inlet 310 and premix dish 300 inclination angle be set to combustion gas.This setup can make to enter just mixed chamber 810 with the rotating shaft state by the wind that air inlet 310 is advanced, and realizes better premixing effect.The inclination angle effect of set air inlet both can be the clockwise air inlet that clockwise direction is provided with the inclination angle; It also can be the counterclockwise air inlet that the inclination angle counterclockwise is set.
(4) be arranged on expansion cavity 830 exits, have the tray for combustion 400 of pre-mixing gas combustion outlet 410.
Described tray for combustion 400 is provided with pre-mixing gas combustion outlet 410, is encapsulated in the exit of expansion cavity 830, the combustion gas and the air Mixture of carrying out abundant premix in the expansion cavity 830 can be derived, and burns.Further, in order to strengthen combusting firepower, pre-mixing gas combustion can be exported between the axis of 410 passage and tray for combustion 400 inclination angle is set.After being provided with like this, fuel gas mixture can rotated derivation tray for combustion 400, thereby realize more sufficient combustion efficiency.Set inclination angle effect both can be that the inclination angle counterclockwise is set, corresponding pre-mixing gas combustion outlet counterclockwise; Also can be that clockwise direction is provided with the inclination angle, corresponding pre-mixing gas combustion outlet clockwise.
(5) aforesaid big fire section gas nozzle 610, it nestles up premix dish 300, is arranged on the big fire section air pipe outlet place of just mixing in the chamber 810.
Set big fire section gas nozzle 610 mainly is to be used for combustion gas is imported to just mixed chamber 810 from big fire section blast tube 600.In the present embodiment, big fire section gas nozzle 610 nestles up premix dish 300 and is provided with.
(6) shower nozzle combustion gas shunt 500, corresponding the position of big fire section gas nozzle 600 is arranged on premix dish 300 outsides, includes big fire section blast tube 600 and little fire section blast tube 700.
(7) be nested in big fire section gas nozzle 610 inboards, the little fire section Gas Pipe 710 that is connected with little fire section blast tube 700 in the shower nozzle combustion gas shunt 500.
Shown in the ginseng figure, in whole premix chamber 800, little fire section Gas Pipe 710 is not provided with any gas outlet.Corresponding big fire section gas nozzle 610, a little fire section Gas Pipe 710 is nested in big fire section gas nozzle 610 inboards.This structure can be strengthened the compact of big fire section, little fire section gas outlet effectively.
In addition, corresponding between the little fire section Gas Pipe 710 of big fire section gas nozzle 610 and inboard intussusception, be provided with the little fire section tracheae fixed seal ring 711 of fixedly big fire section gas nozzle 610 usefulness, can limit the position of big fire section gas nozzle 610 effectively.
(8) aforesaid little fire section gas nozzle 730 is arranged on the little fire section Gas Pipe exit that extends tray for combustion 400 outsides.
Shown in the ginseng figure, little fire section gas nozzle 730 is arranged on the outside of tray for combustion 400.Common operating position is such: utilize ignitor 900, can easily the combustion gas that is discharged in the little fire section gas nozzle 730 be lighted, further, when the pairing fuel gas mixture of big fire section is derived from tray for combustion 400, it can be lighted rapidly.In combustion process, the combustion flame of little fire section gas nozzle 730 is an ever-burning flame; But do not limit yet.
When the calory burning of needs is lower, just can close the fuel gas mixture of big fire section, allow combustion gas directly from little fire section gas nozzle 730, derive and burn.This setup helps conserve energy.
In addition, between described tray for combustion 400 and little fire section gas nozzle 730, be provided with the little fire section nozzle duct 720 that is used for the combustion gas of the little fire section of conducting.A little fire section nozzle duct 720 is a hollow structure, is installed in the circular hole position of tray for combustion 400 centres during use.
(9) the correspondence little section gas nozzle 730 that catch fire is arranged on the ignitor 900 in tray for combustion 400 outsides.
Ignitor 900, can provide suitable ignition voltage by ignition transformer, by accepting to come from the ignition control signal in the supporting combustor, after discharge, light the combustion gas of deriving, or light the premixed gas of deriving through tray for combustion 400 through too small fire section gas nozzle 730.
(10) ion probe 910 that is provided with of the combustion zone in corresponding tray for combustion 400 outsides.
Ion probe 910 can be checked the flame burning state.When flame is in fired state, can make big fire section gas electromagnetic valve and little fire section gas electromagnetic valve in the supporting combustor be in open mode as required; When flame is not in fired state, just can directly closes big fire section gas electromagnetic valve or little fire section gas electromagnetic valve, thereby extinguish protection function is provided.
More than be the description of this invention, and unrestricted, based on other embodiment of inventive concept, also within protection scope of the present invention.
