Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

As shown in figure 1, the biomass hot blast stove comprises a stove body 1, wherein an ash pit 2, a first hearth 3, a second hearth 4 and a third hearth 5 which are communicated with each other are arranged in the stove body 1 from bottom to top. The ash pit 2 and the first hearth 3 are separated by a grate 19. A feeding hole 6 is formed in one side of the second hearth 4, the side wall of the second hearth 4 is communicated with a plurality of air inlets 7, and the air inlets 7 are communicated with an air blower 8. The top of the furnace body 1 is provided with an air outlet 20. An ash outlet 9 is arranged at the bottom of the ash pit 2, the ash outlet 9 is communicated with a screw conveyer 10, and the discharge end of the screw conveyer 10 is also connected with a cooling conveyer 11. The utility model discloses the use: the fuel enters the furnace body 1 through the feeding hole 6 and then falls and burns, falls into the first hearth 3 to continue burning, and then the fuel and the generated smoke and dust enter the second hearth 4 and the third hearth 5 to continue burning, so that the burning is more sufficient, and the generated harmful waste smoke and dust are less. The produced furnace ash can be directly conveyed to a cooling conveyor 11 through a screw conveyor 10 for cooling treatment and then conveyed to other devices, and the cooled furnace ash is directly operated next step, so that the purposes of waste utilization, energy conservation and emission reduction are achieved, and the emission index specified by environmental protection is achieved.

A flue pipe is arranged in the hearth III 5, the flue pipe comprises a straight-tube smoke pipe 12 and a plurality of radiating pipes 13 arranged on the side wall of the straight-tube smoke pipe 12, and one end of the straight-tube smoke pipe 12 penetrates through the top of the furnace body 1. The air in the hearth III 5 exchanges heat with the high-temperature flue gas in the flue pipe, so that the air in the hearth III 5 is heated and is discharged from the air outlet 20 for use in drying places and the like. Because the flue pipe comprises straight section of thick bamboo tobacco pipe 12 and a plurality of cooling tube 13, increased heat transfer area, improved the heat exchange efficiency of living beings hot-blast furnace.
