Preferably, a fuel guide pipe and a fuel gas guide pipe are fixedly arranged on one side of the combustion chamber, a smoke exhaust pipe is fixedly arranged on the other side of the combustion chamber, and the smoke exhaust pipe penetrates out of the hot blast stove and is fixedly connected with the filtering and collecting device.

Preferably, the cold air pipe, the air outlet pipe, the fuel conduit and the fuel gas conduit respectively penetrate out of the hot blast stove.

Preferably, the cross section of the heat exchange conduit is elliptical.

Preferably, the filtering and collecting device comprises a collecting tank and a filter screen, the collecting tank is fixedly arranged at the lower end of the smoke exhaust pipe, and the filter screen is obliquely fixed in the smoke exhaust pipe and arranged on one side of the upper end of the collecting tank.

The utility model has the advantages that: through filtering collection device, can filter the collection by the flue gas that produces in the hot-blast furnace use, realize reuse waste material once more, improve the utilization ratio of the energy, reduce consumption, also can effectual reduction realize certain cleaner production to the pollution of environment.

Description of the drawings:

in order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the embodiments or the prior art descriptions will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings can be obtained by those skilled in the art without creative efforts.

FIG. 1 is a schematic view of the structure of the present invention;

fig. 2 is a schematic view of the structure of the hot blast stove according to the present invention.

In the figure: the device comprises a hot blast stove 1, a filtering and collecting device 2, a storage tank 3, a conveying device 4, a combustion chamber 5, a cold air pipe 6, a heat exchange conduit 7, an air outlet pipe 8, a smoke exhaust pipe 9, a collecting tank 10 and a filter screen 11.

The specific implementation mode is as follows:

the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

As shown in fig. 1 and 2, the present invention provides the following technical solutions: the utility model provides a blue charcoal is dried and is used hot-blast furnace device, includes hot-blast furnace 1, be fixed with on hot-blast furnace 1's the pipe of discharging fume and filter collection device 2, fixedly connected with storage jar 3 on the 2 output of filter collection device, fixed connection conveyor 4 on the 3 output of storage jar, the fuel input fixed connection of 4 output of conveyor and hot-blast furnace 1.

The hot-blast furnace 1 internal fixation is equipped with combustion chamber 5, spiral winding has heat transfer pipe 7 on the 5 lateral walls of combustion chamber, heat transfer pipe 7 input end fixedly connected with cold wind pipe 6, heat transfer pipe 7 output end fixedly connected with goes out tuber pipe 8.

And a fuel guide pipe and a fuel gas guide pipe are fixedly arranged on one side of the combustion chamber 5, a smoke exhaust pipe 9 is fixedly arranged on the other side of the combustion chamber, and the smoke exhaust pipe 9 penetrates out of the hot blast stove 1 and is fixedly connected with the filtering and collecting device 2.

The cold air pipe 6, the air outlet pipe 8, the fuel guide pipe and the fuel gas guide pipe respectively penetrate out of the hot blast stove 1.

The cross section of the heat exchange conduit 7 is oval.

The filtering and collecting device 2 comprises a collecting tank 10 and a filter screen 11, the collecting tank 10 is fixedly arranged at the lower end of the smoke exhaust pipe 9, and the filter screen 11 is obliquely fixed in the smoke exhaust pipe 9 and arranged on one side of the upper end of the collecting tank 10.

The working principle and the using process of the utility model are as follows:
