[0015] The following will be further described in combination with the drawings of the utility model: Figures 1-2 The utility model is further illustrated:

[0016] The utility model provides a novel portable combustion particle hot blast furnace, including the furnace body 1, be provided with the combustion chamber 2 and the heat exchange chamber 10 that communicate with each other in furnace body 1, be provided with hearth 3 in combustion chamber 2, be provided with combustor 4 in hearth 3, be provided with multiple oxygen distribution pipes 6 that communicate with combustion chamber 2 on hearth 3, the top of furnace body 1 is fixedly provided with hopper 5, the bottom of hopper 5 is through furnace body 1 and is communicated with the top of hearth 3, be fixedly provided with multiple back-and-forth heat exchanger 11 in heat exchange chamber 10, one end of multiple back-and-forth heat exchanger 11 is communicated with the middle part of hearth 3 through the communicating pipe 12, the outside of furnace body 1 is fixedly provided with smoke extractor 13, the other end of multiple back-and-forth heat exchanger 11 is communicated with the smoke inlet end of smoke extractor 13, the outside of furnace body 1 below smoke extractor 13 is fixedly provided with air blower 14, the air outlet end of air blower 14 is communicated with heat exchange chamber 10, the side of furnace body 1 away from air blower 14 is provided with air outlet 16, the top of furnace body 1 is provided with controller 17, and controller 17 is electrically connected with combustor 4, smoke extractor 13 and air blower 14.

[0017] In the embodiment, the fuel used by the novel portable combustion particle hot blast furnace is biomass fuel. The furnace body 1, the hearth 3, the hopper 5 and the multiple back-and-forth heat exchanger 11 are all made of stainless steel, which increases the service life, reduces the weight and the volume, and facilitates transportation.

[0018] The combustor 4, the smoke extractor 13 and the air blower 14 can be controlled by the controller 17. The combustor 4 ignites the biomass fuel in the hearth 3, and the biomass fuel combustion heats the hearth 3 and the combustion chamber 2. Under the action of the smoke extractor 13, the flue gas containing heat generated by the biomass fuel combustion enters the multiple back-and-forth heat exchanger 11 through the communicating pipe 12, and then is discharged from the smoke extractor 13. The multiple back-and-forth heat exchanger 11 heats the heat exchange chamber 10. The air blower 14 introduces the external air into the heat exchange chamber 10. The air absorbs the heat of the heat exchange chamber 10, the multiple back-and-forth heat exchanger 11, the combustion chamber 2 and the hearth 3, and then forms hot air which is discharged from the air outlet 16.

[0019] In the embodiment, under the action of the smoke extractor 13, the hearth 3 forms a negative pressure natural combustion, the biomass particle combustion is more complete, and the biomass particle with poor quality does not coke when burning. The combustion is stable for a long time, and is not easy to extinguish. The negative pressure in the hearth 3 can suck the part of air blown by the air blower 14 into the combustion chamber 2 into the hearth 3 through the oxygen distribution pipe 6, and supplement oxygen for the biomass particle combustion.

[0020] The heat exchange chamber 10 is provided with multiple wind baffles 15 matched with the multiple back-and-forth heat exchanger 11.

[0021] In the embodiment, the wind baffles 15 block the air blown by the air blower 14 into the heat exchange chamber 10, so that the air can more fully absorb the heat of the heat exchange chamber 10 and the multiple back-and-forth heat exchanger 11, and improve the heat exchange efficiency.

[0022] The bottom of the furnace body 1 is rotatably provided with a plurality of moving wheels 9.

[0023] In the embodiment, the moving wheels 9 are provided, and the unloading and installation of the furnace body 1 are convenient.

[0024] The furnace body 1 is provided with a furnace door 7 connected with the lower part of the hearth 3.

[0025] In the embodiment, the furnace door 7 can be used to clean the slag produced by the combustion of the biomass particles in the hearth 3.

[0026] The furnace body 1 is provided with an external heat preservation layer 8.

[0027] In the embodiment, the heat preservation layer 8 can reduce the loss of heat in the combustion chamber 2 and the heat exchange chamber 10.

[0028] In summary, the utility model is not limited to the above specific embodiments. Those skilled in the art can make some changes and modifications without departing from the spirit and scope of the utility model. The protection scope of the utility model should be subject to the claims of the utility model.
