For saving cost and simplified structure, the present invention 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 be exactly gasifier of the present invention be 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 that passage is evenly distributed on around the flame of burner for the passage of fuel circulation.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 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 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 it is the most identical that the shape of such shape and flame and heat distribute; Do not influence simultaneously flame again and disperse, give the heating of pot body better on burner top.
The present invention 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 density difference of gas-liquid two-phase and the phenomenon of layering realizes 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.Just gas-liquid separator is that cross section is an annular housing 1 of rectangle as shown in the figure, and is simple in structure like this, and attaching parts reduce.The most important thing is, be positioned at the outside of gasifier, must be subjected to 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 the gas-liquid separator heating surface area maximum of the integral loop of rectangle around 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 that it is far away from flame, need a difficult problem of reliably being heated simultaneously again.
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 pressure drainage gas-liquid separator after the lower fuel gas of density is gasified from the upper strata, enter 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 be 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, has not needed to 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, fuel after the gasification sprays into distributor 3 inner chambers by nozzle 5, 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 enters 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 more mate with gasifier of the present invention and gas-liquid separator.
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 uniform a plurality of boccas 10 of along continuous straight runs just; 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 using method of the present invention: before the igniting, in igniting food tray 4, add an amount of liquid alcohol-group fuel earlier, fuel in the firing point kerosene dish 4, give cavity 1 heating of the body 2 and the gas-liquid separator of gasifier, connect outside dehvery pump immediately, alcohol-group fuel enters the body 2 of coiled coil flame by feed pipe 6, heated body 2 carries out heating and gasifying with the fuel that enters, form the cavity 1 that gas-liquid mixture feeds gas-liquid separator at last, not vaporized liquid fuel been separated in cavity 1 bottom, vaporized fuel gas enters nozzle 5 and distributor 3 by the exhaust outlet 9 that is positioned at cavity 1 top through blast pipe 8, from nozzle 5 at a high speed the fuel gas of ejection carry the air that enters from wind distributing hole 11 and form of bocca 10 ejections of gas oxygen gas mixture by distributor 3 tops.
So far, the once natural air distribution mixing of burner finishes, and by 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, trace liquid fuel mixing high temperature and high pressure gas is discharged into the cavity 1 of gas-liquid separator, liquid fuel in cavity 1 bottom is also gasified rapidly by the hyperthermia radiation of body 2 outer walls, the fuel that enters 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.
