Abstract

Te utility model provides a taper surrounding air inlet type straw gasification furnace, relating to a furnace taking straws as fuel to generate combustible gas. The furnace body consisting of two taper bodies is provided with a feeding port, an air outlet hole and a taper surrounding air inlet ring connected with an ash cabin; the taper surrounding air inlet ring is provided with an air inlet hole; the furnace body is provided with an air outlet hole, a material stirring and pressing bar extends into the furnace body, the ash cabin is provided with an ash outlet, the bottom of the taper surrounding air inlet ring is provided with an air inlet hole and an ash removing hole, and the ash cabin is provided with a tar reclaiming hole. When the taper surrounding air inlet type straw gasification furnace is used, various plant straws are put into the furnace body, a blast blower blows wind to the taper surrounding air inlet ring through the air inlet hole, the wind is blown to various ignited plant straws through a plurality of rows of air inlet holes of the taper surrounding air inlet ring, various plant straws generate combustible gas inside the high temperature and oxygen-deficient furnace body, and the combustible gas is outputted from the air outlet. The taper surrounding air inlet type straw gasification furnace adopts the taper surrounding air inlet ring, is not easy to plug the air inlet, and has large and even heating area of raw materials, long time of banking the fire, sufficiency burning and convenient ash outputting; and the raw materials can automatically fall down in the burning process and does not pollute the environment.

Description

Conical ring is around the air intake stalk gasifier

Technical field

It is the stove that fuel produces imflammable gas with stalk that the utility model relates to a kind of.

Background technology

Existing gasification furnace has a lot, and its structure is different, the effect difference.A kind of stalk infrared gasification stove that existing Beijing clear mahatma section produces, its feed bin is a cylinder, and the side air admission mouth is established in the cylinder bottom, and raw material is packed into behind the feed bin, easily stops up air inlet, makes the raw material heating surface area little, easily burns, fire-sealing time is short; , there is certain expansive force in raw material compacting when burning in the storehouse between raw material and the bulkhead, fuel is difficult in combustion process from falling; Ash discharge is young, the ash discharge difficulty; Do not have the tar recvery facility, can cause environmental pollution.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, and it is big and evenly, fire-sealing time is long, sufficient combustion to aim to provide a kind of heating surface area, can fall certainly in the burning, and ash discharge is easy, and the little conical ring of environmental pollution is around the air intake stalk gasifier.

The implementation of the utility model purpose is, conical ring is around the air intake stalk gasifier, on the body of heater of forming by two bullets 5 charging aperture 4 is arranged, venthole 16, the bottom has the conical ring that links to each other with the grey storehouse 9 that falls to move into solar or lunar halo 7, conical ring moves into solar or lunar halo 7 many row's fresh air inlets 8, refractory insulating layer 6 is arranged in the body of heater, venthole 16 is arranged at top, outside the charging aperture 4 seal groove 3 is arranged, and feed cap 14 is arranged on the seal groove 3, stirring compressing rod 1 stretches in the body of heater by the hole on the feed cap 14 15, there is ash hole 12 in the grey storehouse 9 that falls, and ash hole 12 is outer seal groove 13, and seal cover 11 is arranged on the seal groove, conical ring moves into solar or lunar halo 7 bottoms fresh air inlet 17, ash disposal hole 19, there is tar recovery holes 18 in the grey storehouse 9 that falls.

When using the utility model, various straws are put into body of heater 5, cover feed cap 14, move into after solar or lunar halo 7 places light at conical ring, light the various straws on it, air blast moves into the solar or lunar halo air blast by fresh air inlet 17 to conical ring, wind blows to the various straws of having lighted through many rows fresh air inlet 8 that conical ring moves into solar or lunar halo 7, various straws produce imflammable gas in the body of heater of high temperature anoxic, imflammable gas is by venthole 16 outputs, the combustion ash material falls into grey storehouse 9, discharges from ash hole 12.

The utility model adopts conical ring to move into solar or lunar halo 7, and conical ring moves into solar or lunar halo to arrange fresh air inlets 8 more, and wind enters in the body of heater from a plurality of fresh air inlets 8, and fresh air inlet is difficult for stopping up, and the raw material heating surface area is big and even, fire-sealing time length, sufficient combustion; There is ash hole 12 in the grey storehouse 9 that falls, and ash hole 12 is outer seal groove 13, and the ash discharge sealing is convenient; Body of heater 5 is made up of two bullets, can fall certainly in the material combusting; There is tar recovery holes 18 in the grey storehouse 9 that falls, and tar reclaims, environmentally safe.
