Description

Novel light oil gasification burner

The utility model relates to a kind of novel light oil gasification burner.

The light oil that is in a liquid state under normal temperature and pressure conditions, its Main Ingredients and Appearance are that (molecular formula is C to carbon five ₅H ₁₂), be the accessory substance of petrochemical industry department at present, have advantages such as resource is sufficient, calorific value is high, nontoxic, it is little, inexpensive to pollute, accumulating convenient, the fast province that builds a station, DEVELOPMENT PROSPECT is arranged very much.For this reason, scientific and technical personnel have done many useful exploration and practices, but up to the present, the cooking stove of exploitation is still far from perfect, mostly not proper because of selected gasification method, so that have one or more of following drawback: 1, residual liquid is too much, 2, fume pollution is overweight, 3, noise jamming is too strong, 4, need manually inflate, 5, the restriction that is subjected to have a power failure, 6, cause the full mixing chamber of spray lighter hydrocarbons fuel oil earlier as the maloperation meeting, even overflow, because of its flash-point low, volatile, thus the hidden danger of fire hazardous is arranged, so that it is applied still and is obstructed.

Task of the present utility model is: provide a kind of safe, do not cause the hidden danger of fire because of maloperation, gasification method is reliable and practical, sufficient combustion, thermal efficiency height, pollute little, no raffinate, noiselessness, need not manually inflate, not be subjected to the restriction that has a power failure, the novel light oil gasification burner that is easy to promote.

Task of the present utility model is achieved in that novel light oil gasification burner is by can anti-misoperation causing that the rotary switch interlock of fire, the burner with straight shape generating tube, the autoelectrinic igniting air supply system that is used for the preheating generating tube and auto-supply system four parts of fuel gasification form.

One of its feature is: the straight shape generating tube 5 of dress minute hand valve 6 in pipe tail dress spray vapour lock 14 and the pipe is radially passed under the outer annular distance fire lid 8 of mixing chamber 7 and the inferior high-temperature region on the interior annular distance fire lid 9, allow the flame space on it utilize best well, and be difficult for carbon distribution, also improved the thermal efficiency of cooking stove, overcome in the past straight shape generating tube is placed drawback on the whole fire lid.

Two of its feature is: the pipe tail of gooseneck 15 tangentially communicates with the mixing chamber 7 of shell like round cup shape, its mouth of pipe is corresponding with the spray vapour lock 14 floating Kongxiangs of generating tube, sky is divided into outer annular distance 11, interior annular distance 12 and centre bore 13 3 parts in its mixing chamber, approximate 20: 4: 1 of the optimal proportion of three's area, outer annular distance fire of aspect ratio lid 8 of annular distance fire lid 9 is low in it, so its wind loading rating extra-heavy.

Three of its feature is: its air nozzle 16 and spray point 17 are suspended in the bottom of center fire hole 13 rightly, preheated fuel gas is sprayed after electric spark is lighted from air nozzle 16, be flushed to 10 fully burnings of far infrared energy-saving net at its top, its heat energy width of cloth is up and down penetrated, and both the preheating generating tube 5, and also hot object is desired in heating, its advantage promptly is equivalent to the without preheating time, both do not had fume pollution, noiselessness disturbs again, also is not subjected to the restriction that has a power failure.

Four of its feature is: between air valve knob 1 and needle-valve knob 2, is provided with and do not turn on earlier as the air valve knob 1 that is used for preheating, and the rotary switch interlock that can't turn on of needle-valve knob 2 then, thus eliminated the hidden danger that causes fire because of maloperation.

The rotary switch interlock comprises air valve knob 1, needle-valve knob 2, bayonet lock 23, spring 24, needle-valve knob 2 are sleeved on outside the air valve knob 1, with one heart disalignment, when original shut state, bayonet lock 23 snaps in the needle-valve knob 2 from air valve knob 1 under the effect of spring 24, and only in air valve knob 1 axial advance and after forward valve is driven in rotation, needle-valve knob 2 could counter-rotating be driven valve.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of the utility model burner.

Fig. 3 is the utility model rotary switch interlock figure.

Before the use, it earlier is 4/5ths light oil of oil tank total measurement (volume) to the oil tank input capacity, by gas valve 19 an amount of liquefied gas of input or manually squeeze into an amount of air automatically, the Pressure gauge 20 of oil tank is indicated between 0.05-0.2MPa all the time again by refueling the port lid breather cheek valve 21 of holding concurrently.

The blow-on program: (1) opens gas tank angle valve 18 and oil tank angle valve 22 earlier, again air valve knob 1 is advanced and the dextrorotation certain angle, after being pushed into interlock and being triggered to electric spark on the spray point 17 and lighting from the liquefied gas of air nozzle 16 ejection, therefrom the bottom in internal heat hole 13 is flushed to 10 completing combustions of far infrared energy-saving net on it, preheating is carried out in stage casing to generating tube 5, simultaneously also heating the desire hot object, at this moment, the rotary switch interlock is untied.

(2) open oil pipe fuel tap 4 again, the fuel oil that has certain pressure in the oil tank flows into generating tube automatically, because of its boiling point is low, promptly is vaporized in hot 1-2 minute so only need give.

(3) anticlockwise needle-valve knob 2 slowly, gas promptly sprays in a steady stream from spray vapour lock 14, through gooseneck 15 injections to mixing chamber 7 and air after best the mixing, promptly respectively inside and outside it ring fire lid go out and run into just completing combustion behind the flame of preheating, be flushed to the heat energy radiation up and down of 10 burnings of far infrared energy-saving net from interior ring fire lid 9, main effect is that the fuel oil in the generating tube 5 is carried out self-preheating, forms the benign circulation process of limit preheating, limit vaporization, limit burning, limit preheating.

(4) at this moment gasification burner has entered normal operating conditions, then air valve knob 1 left-handed resetting promptly can be closed preheating air valve 3.

The angle of control needle-valve knob rotation, the size that can at random regulate flame, because of the air pressure in the oil tank more stable, so that its flame does not have view is big or turn down and can both guarantee normally smooth combustion for a long time.

When closing stove, close oil pipe fuel tap 4 earlier, again 2 dextrorotation of needle-valve knob are resetted, make bayonet lock 23 under the effect of spring 24, snap in the needle-valve knob 2, allow its two knob return to chain state, with anti-misoperation from air valve knob 1.As no longer blow-on on the same day, for the purpose of safer, should close gas tank angle valve 18 and oil tank angle valve 22 again.

Comprehensively it seems, the utlity model has safe and reliable, economical and practical and clear The advantages such as clean health are easy to promote, and are particularly suitable for dining room, hotel and town-dweller-rural-family Use, to alleviating the cooking fatigue, environmental contamination reduction is alleviated supplying gaseous fuel Nervous situation will be brought into play positive facilitation, have very big economy, society And environmental benefit.
