Description

The novel biomass gasifying stove

Technical field

The present invention relates to a kind of improvement of cooking stove, particularly a kind of novel biomass gasifying stove.

Background technology

At present, vast rural area, particularly mountain area and upper level rural area; Domestic energy, remaining with the bavin firewood is master's the traditional life energy, because the still traditional life cooking stove that uses mostly; Backward in technique, extensive, the inefficiency of operation; And now general straw gasification stove, because technical deficiency, the gasification of suitable bavin firewood is not used.So every year is not only wasted a large amount of renewable sources of energy in vast rural area, and living environment and ecological environment are had a strong impact on generation, also the healthy generation to people necessarily endangers.

Summary of the invention

The object of the invention will provide a kind of novel biomass gasifying stove exactly, and its can suit gasification of bavin firewood is used, and can not impact living environment and ecological environment.

The objective of the invention is to realize like this: a kind of novel biomass gasifying stove, comprise kitchen range, bell, furnace wall, flue and raw material lowering or hoisting gear, kitchen range is arranged at the bell top, and upper furnace is set in the bell; The burning cover is arranged at the flue top, and the upper end, furnace wall has fresh air inlet, and fresh air inlet ring oven wall is offered, and the fresh air inlet periphery is provided with air bells cap; The furnace wall middle position is provided with flue, is concentric circles and is connected with the bottom, furnace wall, and several pieces conducting strips that are being equally spaced around the flue are radial with flue and are connected; The flue middle part has the ring-type gas outlet, in the following flue of gas outlet grate is arranged, and the bottom of flue is provided with air door; Grate is the combustion chamber with top in the flue, and flue is outer to be that bearing material chamber, middle part are that vaporizer, bottom are material storing room to top between the furnace wall, and is logical in the last middle and lower part; The raw material lowering or hoisting gear comprises discoid care feed tray, pallet connecting rod, pallet shadoof and shadoof jump ring, and care feed tray is positioned at material storing room, and the position of corresponding conducting strip has breach on the care feed tray; Be convenient to conducting strip and pass through, care feed tray can be upper and lower mobile in material storing room, and the care feed tray both sides are symmetrical set the pallet connecting rod; The pallet connecting rod passes the furnace wall and is connected with the pallet shadoof, and pallet shadoof and contact position, furnace wall have vertical breach, and the pallet shadoof can be moved up and down; The pallet shadoof is with sleeve pipe outward, is connected the sleeve pipe lower end closed with the furnace wall; The shadoof jump ring is settled in the upper end, and the one side of pallet shadoof is designed with a plurality of equidistance teeth, is used for shadoof jump ring location.

Owing to adopt said structure, so the gasification of suitable especially bavin firewood is used, burning is used, and firepower is powerful, the smokeless and dust free odorlessness.And the product after the material gasification burning is a charcoal, and the use of can burning once more is energy-efficient.

The specific embodiment

As shown in Figure 1, a kind of novel biomass gasifying stove comprises kitchen range 1, bell 3, furnace wall 16, flue 4 and raw material lowering or hoisting gear, and kitchen range 1 is arranged at bell 3 tops; Upper furnace 4 is set in the bell 3, and burning cover 2 is arranged at flue 4 tops, and 16 upper ends, furnace wall have fresh air inlet 5; Fresh air inlet 5 ring oven walls 16 are offered, and fresh air inlet 5 peripheries are provided with air bells cap 7, and furnace wall 16 middle positions are provided with flue 4; Be concentric circles and be connected with 16 bottoms, furnace wall, several pieces conducting strips 6 that are being equally spaced around the flue 4 are radial with flue 4 and are connected; Flue 4 middle parts have ring-type gas outlet 8, in the following flue 4 of gas outlet 8 grate 10 are arranged, and the bottom of flue 4 is provided with air door 15; Grate 10 is the combustion chamber with top in the flue 4, and flue 4 is outer to be that bearing material chamber, middle part are that vaporizer, bottom are material storing room to top between the furnace wall 16, leads in the last middle and lower part; The raw material lowering or hoisting gear comprises discoid care feed tray 13, pallet connecting rod 14, pallet shadoof 11 and shadoof jump ring 9, and care feed tray 13 is positioned at material storing room, and the position of corresponding conducting strip 6 has breach on the care feed tray 13; Be convenient to conducting strip 6 and pass through, care feed tray 13 can be upper and lower mobile in material storing room, and care feed tray 13 both sides are symmetrical set pallet connecting rod 14; Pallet connecting rod 14 passes furnace wall 16 and is connected with pallet shadoof 11, and pallet shadoof 11 has vertical breach with 16 contact positions, furnace wall, and pallet shadoof 11 can be moved up and down; Be with sleeve pipe 12 outside the pallet shadoof 11, be connected sleeve pipe 12 lower end closed with furnace wall 16; Shadoof jump ring 9 is settled in the upper end, and the one side of pallet shadoof 11 is designed with a plurality of equidistance teeth, is used for shadoof jump ring 9 location.

The present invention is according to macromolecule long-chain solid hydrocarbons such as celluloses, 500 ⁰C-800 ⁰During C, the anoxybiotic cracking is that the principle research and development of the gaseous hydrocarbon of short chain form.

The concrete step of using is:

One, charging

Take off bell 3, Rotary tray shadoof 11 is reduced to the bottom with care feed tray 13, will be sawn into isometric firewood (firewood length can not surpass vaporizer) vertically pack into material storing room and vaporizer in the stove then, fills bell 3 on the bonnet, checks whether bell 3 covers reality completely.

Two, igniting

Open air door 15, a small amount of charcoal (this stove and accessory itself has the function of system charcoal) or firewood are put into the combustion chamber, and light, by charcoal heating flue 4 and conducting strip 6, make heat pass to firewood rapidly, after a few minutes, firewood just gasifies.

Three, burning is used

Gas after the gasification is derived by gas outlet 8, is gone into combustion chambers burn by suction, and second gasification.Combustion gas is internal combustion in the combustion chamber, and on be drawn to 2 burnings of burning cover.After this no longer need add charcoal.Damper 15 sizes make flame become optimum state.Along with the gasification of vaporizer firewood, progressively promote pallet shadoof 11, material storing room's firewood is risen, satisfy the requirement of sustained combustion.Also the firepower size is regulated in the up-down of scalable pallet shadoof 11.

Four, flame-out

Before flame-out, pallet shadoof 11 is transferred to decline, close air door 15, the sealing fire door gets final product.

Five, discharging

The firewood gasification finishes in the stove, after cooling, takes off bell 3, takes out charcoal.
