Embodiment
The utility model is not limited by following embodiments, can according to the technical solution of the utility model and actual conditions come
Determine specific embodiment.
In the utility model, for the ease of description, the description of the relative position relation of each part is according to specification
The Butut mode of accompanying drawing 1 is described, such as：The position relationship of upper and lower, left and right etc. is the Butut according to Figure of description
Direction determines.
The utility model is further described with reference to embodiment and accompanying drawing：
Embodiment 1, as shown in Figure 1, this is dried using the device of boiler afterheat drying wood powder based on boiler afterheat is utilized
The device of wood powder realizes that the device of wood powder is dried using boiler afterheat includes boiler 1, flue 2, economizer 3, flame trap 4, insulation
Pipe 5, centrifugal induced draught fan 6, tube auger 7, wood powder feed bin 8 and cyclone separator 9；The exhaust opening of boiler 1 and the entrance point of flue 2
It is fixedly installed togather, economizer 3 is installed with the vertical section of flue 2, it is also solid on the flue 2 after economizer 3
Dingan County is equipped with flame trap 4, and the port of export and the entrance point of insulating tube 5 of flue 2 are fixedly installed togather, consolidated at the middle part of insulating tube 5
Dingan County is equipped with centrifugal induced draught fan 6, and material outlet end and the insulating tube 5 before centrifugal induced draught fan 6 of tube auger 7 are fixedly mounted on
Together and connecting, the material inlet end of tube auger 7 is fixedly installed togather and connected with the material outlet end of wood powder feed bin 8,
The import of the port of export of insulating tube 5 and cyclone separator 9 is fixedly installed togather.
The device that wood powder is dried using boiler afterheat using this realizes that the method for wood powder drying is carried out in the steps below：Start
Centrifugal induced draught fan 6, centrifugal induced draught fan 6 make to produce negative pressure in the insulating tube 5 before it, the high-temperature flue gas in the burner hearth of boiler 1 are inhaled
Go out, high-temperature flue gas flows through flue 2, and heat tentatively passes through the recycling of economizer 3, and then high-temperature flue gas continues through flame trap
Introduced after 4 and high thermal current is formed in insulating tube 5, high thermal current forms malleation air-flow, malleation air-flow after centrifugal induced draught fan 6
It is flow to along the insulating tube 5 after centrifugal induced draught fan 6 in cyclone separator 9, finally by the emptying tubes rows of cyclone separator 9
