Abstract
The present invention relates to a kind of small-sized biomass direct combustion hotblast stove, including storage bin, combustion chamber, turn smoke-box, heat exchanger.Hearth combustion is blown by automatic blowing machine through smoke pre-heating in storage bin after the biomass fuels stripping and slicing such as straw, stalk crushing.The flue gas of generation enters through furnace outlet turns smoke-box, and through more backhaul dedustings, ash content is deposited by ash port and excluded, and flue gas enters heat exchanger after ash disposal.Flue gas, which enters after smoke pipe is exchanged heat with the air outside pipe, to be discharged, and is entered storage bin heating newborn substance fuel through the external smoke pipe that turns, is discharged by outlet.Air is entered in volute type air channel by combustion chamber upper inlet, is tentatively exchanged heat with burner hearth, is entered heat exchanger by turning smoke-box air connecting tube, is exchanged heat in heat exchanger with the flue gas in smoke pipe, be discharged by air outlet slit.Unique chamber structure, more backhaul heat exchanger structures and tail flue gas pre-heating fuel can effectively reduce exhaust gas temperature, improve the efficiency of hot-blast stove.
Description
Technical field
The present invention relates to a kind of small-sized biomass direct combustion hotblast stoves.
Background technique
Current various biomass thermal wind furnaces are firing biomass fuel stick, and raw material can not directly be utilized by needing to buy.
Rural area has a large amount of biomass straw, and the raw materials such as rice straw cannot efficiently use.
Greenhouse gardening, grain, seed agricultural and sideline product are dry, and special livestock breeding etc. is required to warm-air supply.But it is above-mentioned various
Industry is located at rural area, more dispersed, can not effectively provide centralizedly supply.
A kind of small-sized biomass direct combustion hotblast stove of this programme can effectively utilize farming raw material, efficiently make a living
Generate the demand living that hot wind is provided, solves to heat source.
Summary of the invention
Of the invention and a kind of small-sized biomass direct combustion hotblast stove.
The present invention is implemented as follows:
The biomass fuels such as straw, stalk store and tentatively pre- by flue gas after preliminary stripping and slicing crushing in storage bin
Heat.Combustion chamber blanking port is fallen by storage bin outlet, is blown into combustion chamber by automatic blowing machine, the fixed grate in burner hearth
Upper carry out full combustion.Ash after incineration is fallen into ashcan, and the flue gas of generation is in burner hearth and in hearth wall outer helical channel
Air tentatively exchange heat after by burner hearth exhanst gas outlet enter turn in smoke-box.
Turning has muti-piece to turn smoke-box smoke barrier in smoke-box is separated into multiloop exhaust gases passes.Flue gas is in the channel by repeatedly turning
To after natural dedusting, ash content is deposited by ash port, is excluded by ash door,
Flue gas is entered in heat exchanger by turning smoke-box outlet after ash disposal.
After flue gas enters the more backhaul heat exchange of air progress outside smoke pipe and pipe in heat exchanger, heat exchanger is left, through external turn
Smoke pipe enters in storage bin, after newborn substance fuel preheats in storehouse, is discharged by outlet.
Air is entered in the spiral of air channel of combustion chamber by combustion chamber upper inlet, is carried out just with hearth wall other side flue gas
Step heat exchange, enters in heat exchanger by turning the indoor air connecting tube of cigarette, carries out more times in heat exchanger with the flue gas in smoke pipe
Cheng Huanre is discharged by air outlet slit.
The utility model has the advantages that
The present invention relates to a kind of small-sized biomass direct combustion hotblast stoves, can efficiently utilize the biomass such as rural surplus stalk
Raw material is greenhouse gardening, and grain, seed agricultural and sideline product are dry, and special livestock breeding etc. provides heat source.It can be effectively reduced hot-blast stove
Heat loss in burner hearth improves fuel availability, reduces flue gas loss, reduces pollutant emission.
