Abstract

The utility model relates to a methyl alcohol vaporizing stove, which is the improvement of the existing of liquid vaporizing combustion device. The combustion device of the utility model is a cylindrical body which is composed of an inner and an outer casing; the center of the cylindrical body is a wind tunnel and a vaporizing chamber is arranged between the inner and the outer casing; the lower part of the inner casing is provided with capillary holes; the fuel can ooze to form a primary combustion zone; the fuel is heated and vaporized in the vaporizing chamber to spray from spray holes from top, forming a main combustion zone; air supply can be strengthened because of the existence of the central wind tunnel. Having the advantages of completeness of combustion, high flame temperature and convenient ignition, the utility model is especially suitable for alcohol water type methanol fuels.

Description

Methyl alcohol vaporizing stove

The utility model relates to a kind of methyl alcohol gasification burner, is a kind of liquid fuel evaporation burner.

Methyl alcohol more and more obtains people's attention as a kind of new domestic fuel.The quality of methyl alcohol stove performance has great importance to the popularization of methanol fuel.Alcohol water fuel cost is low, pollute little, yet this fuel is then higher to the requirement of kitchen range, generally adopts preheating vaporization combustion mode, spray combustion after liquid fuel is vaporized in preheating pipe, fuel tank needs pressurization usually, at preheating just, ignition phase, the burning of this kitchen range is also insufficient, the residual amount of methyl alcohol in the exhaust gas discharged, carbon monoxide and content of formaldehyde use also inconvenient than higher.

The purpose of this utility model is to disclose a kind of sufficient combustion, flame temperature height, easy to operate methyl alcohol gasification burner, is a kind of gasification burner of particularly suitable alcohol water type methanol fuel.

Task of the present utility model is to realize like this, the burner of described methyl alcohol gasification burner is the column that a central wind-tunnel that is made of the metal inner and outer cover and ring-type vaporization chamber combine, the bottom of inside and outside cover is connected with a pallet, seal on the top of inside and outside cover, be provided with spray-hole above, the bottom of described inner cover is provided with capillary seam or pore, and woven hose is introduced described pallet position.

Operation principle of the present utility model is different from existing preheating evaporation burner.At inner cover bottom and pallet connecting portion, because methanol fuel oozes out from capillary seam or pore, to light the back and form first combustion zone, its effect is heating inner cover and air inducing.The liquid fuel that is in ring-type vaporization chamber bottom from the ejection of top spray-hole, forms second combustion zone, promptly main combustion zone for metal cover body heating vaporization forms jet-stream wind.The existence of central authorities' wind-tunnel makes the central authorities of main combustion zone can obtain enough air, guarantees sufficient combustion.The main feature of this burner is to adopt unpressurized large tracts of land heat conduction preheating vaporization mode, so receiver need not pressurize, adopting capillary percolation is the fuel supply mode of combustion preheater, the exhaust airstream of first combustion zone enters main combustion zone, so the burning quality of first combustion zone does not influence the burning quality of whole burner; Adopting central wind-tunnel to strengthen air inducing mode guarantees sufficient combustion and improves flame temperature.This burner can directly use common pure water type methanol fuel, and for example moisture 15% thick methanol solution need not add other auxiliary agents, and main combustion zone flame temperature can be up to more than 1000 ℃, and the discharge capacity of oxious component is far below state health standards.

Below in conjunction with drawings and Examples, the utility model is specified.

Fig. 1 is a methyl alcohol gasification burner overall structure schematic diagram.

Fig. 2 is a burner assembled shaft mapping.

Body of heater 1 top is support 2 among Fig. 1, and the front portion is provided with fluid storage tank 3, and the middle part is a burner 4, and these burner 4 main bodys are the column 5 that a metal inner and outer cover constitutes, and is provided with a upward cover bucket 6.The drain pipe 7 of fluid storage tank 3 bottoms is connected with woven hose 9 through a needle valve switch 8, and this woven hose 9 is connected with column 5 bottoms.

Be respectively cover bucket 6, vaporization chamber loam cake 11, metal inner cover 12, metal housing 13, overflow coil pipe 14, woven hose 9 and pallet 15 among Fig. 2 from top to bottom.Metal inner and

outer cover

12,13 tops are connected with vaporization chamber loam cake 11 seals, and bottom and pallet 15 sockets form vaporization chamber.Loam cake 11 is provided with spray-hole 16.The central authorities of inner cover 12 are wind-tunnel.The bottom of inner cover 12 has some sealings 17, so that form a capillary seam endless belt at matching part when adorning with the inner ring sleeve of pallet 15, oozes out for liquid.This is a kind of simple and easy and practical scheme that capillary seam hole is set.The capillary seam also can substitute with the capillary aperture, and method is to bore some apertures in column inner chamber bottom, forms a pore endless belt.Outer cover 13 is tightly connected with pallet 15.Woven hose 9 has the overflow pipe 14 of one section extension at pallet after the sidepiece of pallet 15 is introduced, uniform spout hole 18 makes liquid flow out to pallet 15 on the pipe.This section overflow pipe 14 can save, and woven hose 9 is connected with pallet 15 sidepieces, and makes under the pipe port curvedly, and liquid that can not is flowed out from connecting portion.Also can establish an electronic ignition (not shown) in column central authorities wind-tunnel bottom.Last cover bucket 6 tops are provided with siderochrome aluminium net 19, and staving 20 is trapped among the periphery of outer cover 13.

Lighted the back from pallet 15 and the crevicular exudate fuel of inner cover 12 connecting portion capillarys during operation and form first combustion zone, heating inner cover 12 makes in the pallet 15 liquid fuels vaporize in vaporization chamber and spray from spray-hole 16.The fuel of ejection mixes the back by 19 after-combustions of siderochrome aluminium net with air, form main combustion zone.Central authorities' wind-tunnel is strengthened air inducing, for main combustion zone central authorities provide enough air.The discharging of first combustion zone is introduced main combustion zone through central wind-tunnel, so whether its sufficient combustion does not influence the burning quality of whole burner.Vaporization chamber has hot conducting surface of large tracts of land and bigger space, and vaporescence rise to conduct heat with air-flow and progressively strengthens, thus the pulse air pressure that is produced when not having the tubular preheater vaporization, thereby the storage liquid container does not need pressurization.

Do not use cover bucket 6, the key property of burner is constant, can improve burning quality but use upward behind the cover bucket 6, and avoid vaporization chamber loam cake 11 inner carbon distributions.The staving 20 of last cover bucket 6 can also play heat-blocking action.
