The specific embodiment

Below in conjunction with drawings and Examples, the utility model is elaborated.

Consult Fig. 1, Fig. 2 and Fig. 3, the utility model combustor comprises a combustion furnace 2, cooling device 3, a first air-flow delivery unit 4 to a dry drum 1, this combustor in order to supply heat energy, and a second air-flow delivery unit 5.

This combustion furnace 2 comprises that one is derived passage 22 around defining the heat energy that a ring wall 21 in order to the combustion chamber 20 of the wood chip that burns, one be arranged at leading section and be communicated with this combustion chamber 20 and this dry drum 1, and a plurality of refractory brick 23 that is arranged at this ring wall 21.This ring wall 21 has this combustion chamber 20 of a vicinity and the internal layer 211 that arranges for described refractory brick 23, one and this internal layer 211 are spaced outer 212, and a cooling chamber 213 that is formed on this

internal layer

211 and 212 of this skins and filling cooling fluid.In the present embodiment, this internal layer 211 is that steel plate is made.

This cooling device 3 is communicated with this cooling chamber 213 and in order to transmit cooling fluid to this cooling chamber 213, cooling fluid can be carried out heat exchange with this internal layer 211 and this skin 212.Whereby, reduce the temperature of this internal layer 211 and this skin 212, to avoid the temperature of described refractory brick 23 too high and produce be full of cracks.

This first air-flow delivery unit 4 is connected in the rearward end of this combustion furnace 2, and in order to the axial transmission air-flow along this combustion chamber 20 to this combustion chamber 20, the heat energy that burning wood chip is produced is along with air-flow is taken this combustion chamber 20 out of and sends in this dry drum 1 via this heat energy derivation passage 22, and this air flow energy of the heat energy of carrying under one's arms is broken through the solid heavy curtain that the heating object in this dry drum 1 forms in the middle of rotation rolling, and fully mixes and carry out heat exchange with heating object.In the present embodiment, this first air-flow delivery unit 4 is an air-blast device, and air-blast device has an outlet pipe 41, and it is 20 extend axially and be communicated with this combustion chamber 20 along combustion chamber.

This the first air-flow delivery unit 4 needs to draw outside air via sending into this combustion chamber 20 after pressurizeing to form air-flow, but because the air themperature of sending to is about 30 ℃ of temperature (being about 700 ℃ to 1200 ℃ under general fired state) that can reduce these combustion chamber 20 interior integral body, therefore, in the preferred embodiment of the utility model combustor, the air-blast device of this first air-flow delivery unit 4 has more an air inlet pipeline 42, be communicated with this dry drum 1, collect and utilize the waste hot gas producing in drying process, after pressurization, form again the air-flow that is sent to this combustion chamber 20, whereby, not only more can effectively maintain the condition of high temperature of this combustion chamber 20, and can be by the waste hot gas that carries out producing in drying process again after interior 700 ℃ to the 1200 ℃ high temperature secondary burning in this combustion chamber 20, effectively reduce soiling value and reduce stink amount.

This second air-flow delivery unit 5 is connected with this combustion furnace 2 and in order to transmit air-flow and wood chip to this combustion chamber 20.This second air-flow delivery unit 5 has an air blast 50 and a plurality of tangential direction along this combustion chamber 20 is connected in this combustion chamber 20 and in order to transmit the wind Pipe Cutting 51 of air-flow.Wherein at least one wind Pipe Cutting 51 is in order to transmit wood chip, and importantly wood chip also can be sent in this combustion chamber 20 via another feeding pipeline 52.

When wood chip is sent into this combustion chamber 20 by the described wind Pipe Cutting 51 of this second air-flow delivery unit 5, because air-flow is that tangential direction along this combustion chamber 20 enters, can make the air-flow of convolution be covered with whole combustion chamber 20, make to there is sufficient air in this combustion chamber 20 and circulation is fully burnt wood chip, to produce high temperature, and supply heat energy to this dry drum 1.

It is worth mentioning that, the utility model combustor, except in order to supply heat energy to above-mentioned dry drum, also can, in order to supply heat energy to other heaters, as boiler and heating furnace etc., and can reach above-mentioned identical effect.

The beneficial effects of the utility model are: the utility model combustor enters this combustion chamber 20 by this first air-flow delivery unit 4 in order to the axial transmission air-flow along this combustion chamber 20, the heat energy that burning wood chip is produced is along with air-flow is taken this combustion chamber 20 out of, and enter this dry drum 1, fully mix with heating object and carry out heat exchange, in addition, this the first air-flow delivery unit 4 can reclaim the waste hot gas producing in drying process and with formation, import the air-flow of this combustion chamber 20, can not only effectively maintain the condition of high temperature of this combustion chamber 20, can reach the environment protecting of recycling waste hot gas again, therefore really can reach the object of the utility model.
