Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Like Fig. 1, shown in 2, a kind of liquid-fuel burner comprises the feed pipe 6 of fuel supplying; And the nozzle 5 that burns of ejection fuel; Feed pipe 6 connects propellant gasifier, and the outlet 7 of gasifier connects gas-liquid separator, and the exhaust outlet of gas-liquid separator connects nozzle 5.Certainly, also be connected with mechanisms such as valve even dehvery pump on the feed pipe 6, and interconnection technique of each parts, technique for fixing etc. belong to known technology, repeat no more.

The improvement of the utility model is to use the mode of gasification, and combustion, simultaneously for guaranteeing that the gasification reliability is provided with gas-liquid separator; Both act synergistically and guarantee gasification result and efficiency of combustion.As for described nozzle 5 can be the nozzle that sprays combustion gas in the prior art arbitrarily, and the nozzle that perhaps plays spraying, hydrojet effect can; Gasifier also has a lot of concrete embodiments, by the device that principle divides for example heating to make fuel gasification, perhaps heats the device of the spray that pressurizes simultaneously etc.; Just more as for concrete structure, as long as can play the effect of vaporising fuel.As for gas-liquid separator a lot of embodiments are arranged also,, for example divide from principle: gravity separator, deflection separator, separator using centrifugal force, silk screen separator etc. as long as play the effect that separates gas-liquid two-phase.

For practicing thrift cost and simplified structure, the utility model further improves and is:

Described gasifier is positioned at around the flame of burner.The scope of flame scope shown in double dot dash line among Fig. 1 of burner, fuel flows to shown in arrow among Fig. 1.Gasifier just can utilize the heat of flame to carry out fuel gasification to heating around being positioned at flame.In other words the gasifier that is exactly the utility model is the heating and gasifying device.Gasifier had both formed around flame and had gone along with sb. to guard him, and intercepted cool ambient air, avoided thermal loss, and energy-conserving and environment-protective have gasification result reliably simultaneously again.

Certainly, above-mentioned gasifier can be the several separate split-type structural, also can be an integral body, and for example: described gasifier comprises the passage that supplies the fuel circulation, and passage is evenly distributed on around the flame of burner.Just gasifier is all-in-one-piece, and the inner chamber by metal shell constitutes passage usually, is heated gasification in the process that fuel circulates in passage, and more a plurality of so split type gasifiers are simple in structure, reduces attaching parts, and guarantees the gasification result homogeneous.Then have a variety ofly as for equally distributed mode, for example the circuitous bending of passage is arranged in around the flame, just be similar to hedge around appearance.Perhaps passage is made up of the inner chamber of body 2, and the body coiling is straight-tube shape and is positioned at the flame outside; Be more preferably: described passage is made up of the tube chamber of body 2, and body 2 helical forms are coiled in around the flame of burner and wholely constitute bell mouth shape, bell-mouthed towards with flame towards consistent.Just body 2 is coiled in the flame outside, but integral body is not straight-tube shape, but bell mouth shape, common burner all is that level is installed, upwards burning of flame so, and gasifier is also with regard to horn mouth for example shown in Figure 1 up.Body 2 coiled coils had both guaranteed time and the heating surface area that fuel is heated, and guaranteed the gasification result of gasifier; Because the shape and the heat distribution of such shape and flame are the most identical; Do not influence simultaneously flame again and disperse, give the heating of pot body better on burner top.

The utility model also provides the structure of preferred gas-liquid separator.Specifically: described gas-liquid separator comprises the cavity 1 of sealing, and the exhaust outlet 9 of described gas-liquid separator is positioned at cavity 1 top.Such gas-liquid separator structure is the simplest, in fact is exactly to utilize the phenomenon of density difference and the layering of gas-liquid two-phase to realize gas-liquid separation, and reliable operation, apparatus structure is the simplest simultaneously, and cost is minimum.

Certainly cavity 1 can be an Any shape, and cavity 1 also can be a plurality of independently cavitys 1, and the outlet 7 of gasifier is communicated with cavity 1 respectively then.Be more preferably: described cavity 1 is looped around gasifier 2 outsides.Gas-liquid separator just as shown in the figure is that cross section is an annular housing 1 of rectangle, and is simple in structure like this, and attaching parts reduce.The most important thing is, be positioned at the outside of gasifier, must receive the heat radiation of flame, not vaporized liquid fuel also can continue to be gasified under the situation of being heated in the separator, and the whole efficiency of burner further improves.The prior advantage of this structure is: under the prerequisite of the heat of the flame that utilizes burner itself, solved arranging between gas-liquid separator and the gasifier again cleverly relation is set, guaranteed that both can both be heated reliably.Cross section is that the overall loop of rectangle is maximum around the gas-liquid separator heating surface area of gasifier; Simultaneously can also be with gas-liquid separator rough and uneven in surface towards the Surface Machining of flame for increasing heating surface area; Further increase heating surface area; Solve its difficult problem far away from flame, as need reliably to be heated again simultaneously.

The exhaust outlet 9 of described gas-liquid separator is an end mouth of pipe of blast pipe 8, and the other end of blast pipe 8 connects nozzle 5.Like this both guarantee the pressure drainage gas-liquid separator after the lower fuel gas of density is gasified from the upper strata, get into nozzle 5 and burn, structure is simple again simultaneously.Also utilize in the gas-liquid separator heat of itself to give pipe insulation, avoid blast pipe 8 oversize and condensation of gas influences efficiency of combustion.

Be more preferably: described gasifier and/or gas-liquid separator below are provided with the igniting food tray 4 of an annular.In fact just the groove of an annular gets final product; The inside can be added small amount of fuel and lighted; The part of fuel no matter heating and gasifying device or gas-liquid separator can both gasify, burner is kept burning with regard to the heat that relies on flame itself then, need not re-use the igniting food tray.Give gasifier or gas-liquid separator preheating when being convenient to first the igniting like this, guarantee just can use burner immediately when needed.And preheating is convenient, does not need other preheating device.

Further, described nozzle 5 connects distributor 3.Just as shown in Figure 1, the fuel after the gasification sprays into distributor 3 inner chambers by nozzle 5, and the fuel gas that sprays at a high speed from nozzle 5 carries an air distribution formation of the air gas oxygen gas mixture that gets into from wind distributing hole 11; The volume of distributor 3 is greater than nozzle 5; The bocca 10 on its top, the puff prot that just sprays fuel gas can disperse to be provided with a plurality of, are more conducive to fuel gas like this and fully contact with air, form another air distribution; Feasible burning is more abundant, and the flame scope is bigger; Also gasifier and the gas-liquid separator with the utility model more matees.

For fuel gas is sprayed more dispersedly, burning more fully.The bocca 10 of described distributor 3 circumferentially is provided with a plurality of and is positioned at the forward side, centre of gasifier along burner.As Fig. 1 just along continuous straight runs be uniformly distributed with a plurality of boccas 10; Fuel gas sprays to such an extent that more disperse like this, and the air-flow that sprays generation negative pressure can contact more abundant from attracting air on four sides with air.

Below in conjunction with Fig. 1,2; To use liquid alcohol base fuel to be example; Specifically introduce the method for using of the utility model: before the igniting, in igniting food tray 4, add an amount of liquid alcohol-group fuel, the fuel in the firing point kerosene dish 4 earlier; Give cavity 1 heating of the body 2 and the gas-liquid separator of gasifier; Connect outside dehvery pump immediately, alcohol-group fuel is through the body 2 of feed pipe 6 entering coiled coil flames, and heated body 2 carries out heating and gasifying with the fuel that gets into; Form the cavity 1 that gas-liquid mixture feeds gas-liquid separator at last; Not vaporized liquid fuel been separated in cavity 1 bottom, and the exhaust outlet 9 of vaporized fuel gas through being positioned at cavity 1 top gets into nozzles 5 and distributor 3 through blast pipe 8, from nozzle 5 at a high speed the fuel gas of ejection carry the air that gets into from wind distributing hole 11 and form of bocca 10 ejections of gas oxygen gas mixture through distributor 3 tops.

So far, the once natural air distribution mixing of burner finishes, and through regulating the degree of depth of nozzle 5 insertion distributor 3, can control the air distribution amount of air distribution for the first time, thereby satisfy the requirement of different fuel type to the air distribution amount.After bocca 10 ejections of gas oxygen gas mixture by distributor; 4 flame or igniter are lighted the back and are produced violent the burning in the quilt igniting food tray; And heat for body 2 and cavity 1 rapidly; Violent flame is gasificated into high temperature and high pressure gas rapidly with the liquid fuel in the body 2, and micro-liquid fuel mixing high temperature and high pressure gas is discharged into the cavity 1 of gas-liquid separator, and the liquid fuel in cavity 1 bottom is also gasified rapidly by the hyperthermia radiation of body 2 outer walls; The fuel that gets into thus in the energy-conservation distributor 3 remains the HTHP gaseous state, has kept the combustion stability of whole combustion system and powerful firepower.Under the situation that the body 2 that powerful flame coils in helical form centers on, be the horn-like the bottom of a pan that is ejected into.Behind the small amount of fuel all burnt in the igniting food tray 4, extinguish naturally.Heating finishes to close down outside dehvery pump and valve can stop heating.
