Abstract
The utility model relates to a small -size living beings direct combustion formula hot -blast furnace, including storage silo, combustion chamber, commentaries on classics smoke -box, heat exchanger. The stripping and slicing of biomass fuel such as straw, straw is smashed the back and is preheated through the flue gas at the storage silo, blows in the furnace burning by the automatic material machine that blows. The flue gas that generates gets into through furnace exit and changes the smoke -box, removes dust through many return strokes, and the ash content is by falling grey salty long -pending getting rid of dusting back flue gas entering heat exchanger. Discharge after air that the flue gas got into tobacco pipe and outside of tubes carries out the heat transfer, get into the new biomass fuel of storage silo heating through external commentariess on classics tobacco pipe, by the export discharge. The air carries out preliminary heat transfer with furnace got into spiral air duct by combustion chamber top entry in, gets into the heat exchanger by changeing smoke -box air connection, in the heat exchanger with the tobacco pipe in the flue gas carry out the heat transfer, discharge through the air outlet. Unique furnace structure, many return strokes heat exchanger structures and tail flue gas preheat fuel can effectual reduction exhaust gas temperature, improves the efficiency of hot -blast furnace.
Description
Technical field
The present invention relates to a kind of small-sized biomass direct combustion hotblast stove.
Background technology
Current various biomass thermal wind furnace is firing biomass fuel rod, needs purchase can not directly utilize raw material.
The raw materials such as rural area has substantial amounts of biomass straw, rice straw can not effectively utilize.
Greenhouse gardening, grain, seed agricultural byproducts are dried, and special livestock breeding etc. is required to warm-air supply.But it is above-mentioned various
Industry is positioned at rural area, more disperses, it is impossible to enough effectively provide centralizedly supply.
This programme one small-sized biomass direct combustion hotblast stove, it is possible to effectively utilize crops raw material, make a living efficiently
Producing lives provides hot blast, solves the demand to thermal source.
Summary of the invention
The present invention and a kind of small-sized biomass direct combustion hotblast stove.
The present invention is achieved in that
The biomass fuel such as Caulis et Folium Oryzae, straw, after preliminary stripping and slicing is pulverized, stores and the most pre-by flue gas in storage bin
Heat.Fallen into combustor blanking port by storage bin outlet, automatic blowing machine be blown in combustion chamber, fixed grate in burner hearth
On fully burn.Ash after incineration falls in ashcan, the flue gas of generation in burner hearth with in hearth wall outer helical passage
The preliminary heat exchange of air after by burner hearth exhanst gas outlet enter turn in smoke-box.
There is polylith to turn smoke-box smoke barrier in turning smoke-box and be separated into multiloop exhaust gases passes.Flue gas is in the channel through repeatedly turning
After natural dedusting, ash is deposited by ash port, ash door get rid of,
After ash disposal, flue gas is entered in heat exchanger by turning smoke-box outlet.
After air outside flue gas enters cigarette tube and tube in heat exchanger carries out many backhauls heat exchange, leave heat exchanger, through external turn
Smoke pipe enters in storage bin, after in storehouse, newborn substance fuel preheats, outlet discharges.
Air is entered in combustor spiral of air passage by combustor upper inlet, at the beginning of carrying out with hearth wall opposite side flue gas
Step heat exchange, enters in heat exchanger through turning the air connecting tube in smoke-box, carries out many times with the flue gas in smoke pipe in heat exchanger
Cheng Huanre, is discharged by air outlet slit.
Beneficial effect:
The present invention relates to a kind of small-sized biomass direct combustion hotblast stove, it is possible to efficiently utilize the biomass such as rural surplus straw
Raw material, for greenhouse gardening, grain, seed agricultural byproducts are dried, and special livestock breeding etc. provides thermal source.Can effectively reduce air stove
Heat loss in burner hearth, improves fuel availability, reduces flue gas loss, reduces pollutant emission.
