Abstract
The invention relates to a small biomass direct burning type hot-blast stove.The small biomass direct burning type hot-blast stove comprises a storage bin, a burning chamber, a smoke transfer chamber and a heat exchanger.Halm, straw and other biomass fuel are diced and smashed, then preheated with smoke in the storage bin and blown to a hearth through an automatic blower for burning.The generated smoke enters the smoke transfer chamber from an outlet of the hearth, through multi-return-stroke dust removal, ash settles and is discharged from an ash fall opening, and the smoke enters the heat exchanger after ash removal.The smoke enters a smoke pipe, conducts heat exchange with air outside the pipe and then is exhausted, and the smoke enters the storage bin through an externally-arranged smoke transfer pipe to heat new biomass fuel and is exhausted from an outlet.The air enters a spiral air channel from an inlet in the burning chamber, conducts preliminary heat exchange with the hearth, enters the heat exchanger through an air connecting pipe of the smoke transfer chamber, conducts heat exchange with the smoke in the smoke pipe in the heat exchanger and is exhausted from an air outlet.Through the special hearth structure, the special multi-return-stroke heat exchanger structure and the special mode that the fuel is preheated with the tail smoke, the smoke exhaust temperature can be effectively reduced, and the efficiency of the hot-blast stove can be improved.
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, it is necessary to buys and 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 dry, and special livestock breeding etc. all needs warm-air supply.But above-mentioned various industry is positioned at rural area, comparatively 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, provides hot blast for productive life efficiently, 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 in storage bin and is tentatively preheated by flue gas.Fallen into combustor blanking port by storage bin outlet, automatic blowing machine be blown in combustion chamber, in burner hearth, fixed grate fully burn.Ash after incineration falls in ashcan, and the flue gas of generation is turned in smoke-box by the entrance of burner hearth exhanst gas outlet with after the preliminary heat exchange of air in hearth wall outer helical passage in burner hearth.
Turning has polylith to turn smoke-box smoke barrier to be separated into multiloop exhaust gases passes in smoke-box.Flue gas is in the channel after repeatedly turning to nature dedusting, and 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 the air outside flue gas entrance cigarette tube and tube carries out many backhauls heat exchange in heat exchanger, leave heat exchanger, enter in storage bin through the external smoke pipe that turns, after newborn substance fuel preheats in storehouse, outlet discharge.
Air is entered in combustor spiral of air passage by combustor upper inlet, preliminary heat exchange is carried out with hearth wall opposite side flue gas, enter in heat exchanger through turning the air connecting tube in smoke-box, in heat exchanger, carry out many backhauls heat exchange with the flue gas in smoke pipe, 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 utilizing the biomass materials such as rural surplus straw, for greenhouse gardening, grain, seed agricultural byproducts dry, special livestock breeding etc. provides thermal source.Can effectively reduce the heat loss in hearth of hot-blast stove, improve fuel availability, reduce flue gas loss, reduce pollutant emission.
