Exchanger（3）The port of export enter dust pelletizing system, housing（1）Upper and snake bend shape heat exchanger（3）The port of export connection set
There is air exhauster（5）, in hot blast furnace shell（1）The other end be provided with cleaning cool air inlet（6）, burner hearth fuel inlet（4）Side
Clean energy resource is provided with above housing to export（7）.
Described biomass thermal wind furnace, snake bend shape heat exchanger（3）Each self-forming of upper and lower end join one it is empty
Chamber, heat exchanger（3）Entrance point upper cavity be designed with deashing chamber（8）, heat exchanger（3）Port of export lower cavity set
In respect of lower deashing chamber（9）.
Described biomass thermal wind furnace, snake bend shape heat exchanger（3）Straight length part by a number of heat conduction
Pipe composition tube bank, the upper end entrance of each heat conducting pipe and lower end outlet and the upper and lower end join of snake bend shape heat exchanger
Integral cavity connection, thermal medium are circulated by restraining in heat exchanger.
The beneficial effects of the utility model：
1st, the utility model biomass thermal wind furnace, on the basis of old-fashioned hot-blast stove, from thermodynamics, materialogy, mechanics
Etc. technique, material, equipment have been done it is detailed improve lifting, devise most reasonable most practical biomass thermal wind furnace, reach
Energy-conservation, efficiently, good drying effect, long lifespan the advantages that.
2nd, the utility model biomass thermal wind furnace, simple in construction, design science is reasonable, safe and reliable.Use boiler
Pipe makes heat exchanger, allows hot blast caused by burning not enter dryer, but passes through filtering heel row and go out stove.Pass through pipe simultaneously
The heat of wall, clean air is heated, form hot blast and enter dryer.By heat exchanger, the thermal source cleaned, ensure that
Grain is non-discolouring after the drying, not taint of odour.Flare is prevented into dryer so as to trigger the danger of fire.
3rd, the utility model biomass thermal wind furnace, temperature are allowed to be adapted to drying grain, add cleaning up and down than relatively low
Mouthful, facilitate client's internal cleaning.It is easy to operate.Fuel not only can be with burning coal, and can also burn branch, rice chaff, stalk, jade
Rice fringe etc..

Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1
Referring to Fig. 1, the utility model biomass thermal wind furnace, containing housing 1, burner hearth 2, heat exchanger 3, burner hearth 2 is arranged on
One end in housing 1, the bottom of side body 1 connects with burner hearth 2 is provided with fuel inlet 4, the generally snake bend shape of heat exchanger 3
（" ∪ " shape, " ∩ " shape hollow-core construction body are connected successively）, thermal medium is at the top of burner hearth 2 into snake bend shape heat exchanger 3
Entrance point, it is roundabout through 2 to 3 times or 4 complications, enter dust pelletizing system, housing 1 from the port of export of snake bend shape heat exchanger 3
Upper and snake bend shape heat exchanger（3）The port of export be connected with air exhauster 5, be provided with the other end of hot blast furnace shell 1 clear
Clean cool air inlet 6, the housing top of the side of burner hearth fuel inlet 4 are provided with clean energy resource outlet 7.
Embodiment 2
Referring to Fig. 1, the biomass thermal wind furnace of the present embodiment, it is with the difference of embodiment 1：Snake bend shape heat is handed over
Each self-forming one cavity of upper and lower end join of parallel operation 3（" ∪ " shape, the top of " ∩ " shape hollow-core construction body join are with
Portion）, the entrance point upper cavity of heat exchanger 3 is designed with deashing chamber 8, and the port of export lower cavity of heat exchanger 3 is designed with
Lower deashing chamber 9（At least under the import top of first " ∪ " hollow-core construction bodily form and last " ∪ " hollow-core construction body
Portion respectively sets one）.
Embodiment 3
Referring to Fig. 1, the biomass thermal wind furnace of the present embodiment, it is with the difference of embodiment 1 or embodiment 2：It is snakelike
