When the temperature of oxygen burning changes over slope less than 0, illustrate that anoxycausis carries out completely, bottom reaction member 20, form high-quality
Powdered carbon.Now blanking and powdered carbon recycling module 93 control action driver element 80 make second be connected with the first movable supporting plate 112
Drive shaft 82 and the 3rd drive shaft 83 action being connected with the second movable supporting plate 212, make the first movable supporting plate 112 and first solid
The first blade 113 and the first intercommunicating pore 114 of determining supporting plate 111 are the most corresponding overlapping, and the second movable supporting plate 212 and second is fixed
Second blade 213 of supporting plate 211 and the second intercommunicating pore 214 are the most corresponding overlapping, and biomass material passes through the first intercommunicating pore 114
Entering reaction member 20, powdered carbon enters powdered carbon recovery unit 30 by the second intercommunicating pore 214.Then, when biomass material and charcoal
After powder respectively enters reaction member 20 and powdered carbon recovery unit 30, blanking and powdered carbon recycling module 93 control action driver element
80 the 3rd drive shafts 83 times making the second drive shaft 82 and the second movable supporting plate 212 connection being connected with the first movable supporting plate 112
Double action is made, and the first blade 113 making the first movable supporting plate 112 and first fix supporting plate 111 is staggered, the second movable supporting plate
212 and second the second blades 213 fixing supporting plate 211 are staggered, and storing unit 10 and reaction member 20 are isolated, reaction
Unit 20 and powdered carbon recovery unit 30 are isolated, and enter subsequent cycle process.When powdered carbon enters in powdered carbon recovery unit 30, charcoal
The temperature of powder is higher, and cooling affects the quality of powdered carbon not in time.Now, blanking and powdered carbon recycling module 93 control air pump 72
Starting, owing to steam recovery unit 70 internal gas pressure reduces, air enters air torus 33 by the second through hole 331, and from
Third through-hole 332 enters steam recovery unit 70.Owing to the powdered carbon of falling to powdered carbon recovery unit 30 has higher temperature,
Air through the air torus 33 of powdered carbon recovery unit 30 sidewall also has higher temperature by heat exchange, is stored in heat
In gas recovery unit 70, and make the temperature of powdered carbon reduce, it is to avoid the high temperature impact on powdered carbon quality simultaneously.It is arranged at steam to reclaim
Hot-air in steam recovery unit 70 is delivered to reaction member 20 by fourth hole 71 and pushes up by the air pump 72 outside unit 70
The first through hole 25 on portion's sidewall, the baffle plate arranged at the first through hole 25, can effectively prevent biomass material from passing through the first through hole
25 enter in steam recovery approach.Owing to hot-air rises, when the first movable supporting plate 112 and first of the first supporting plate 11 is fixed
When first blade 113 of supporting plate 111 is staggered, hot-air enters storing unit 10 by the micropore on the first blade 113；
When the first blade 113 and the first intercommunicating pore 114 points of supporting plate 111 fixed by the first movable supporting plate 112 and first of the first supporting plate 11
During corresponding overlap, hot-air can enter storing unit 10 by the first intercommunicating pore 114 and micropore.Hot-air enters storing unit
After 10, carry out biomass material being dried except water, it is to avoid moisture is too high, reduced the calorific value of biomass material burning, and avoid
Enter with combustible gas in the equipment such as boiler after moisture heat absorption, reduce the efficiency of the equipment such as boiler.After the temperature of powdered carbon reduces,
Described powdered carbon output module 94 controls the frequency of delivery driving element of powdered carbon output unit 60, according to the demand control to powdered carbon
The frequency of delivery of conveyer 61 processed, thus the conveying capacity of powdered carbon is increased or decreased.
Relative to prior art, the biomass gasification device of the present invention, by control unit control feed unit, storing unit,
Reaction member, the operation of powdered carbon recovery unit, and utilize tar heat energy switch technology to give full play to utilize the heat energy of tar, fall
Low energy consumption；Accurately controlled the recovery time of powdered carbon by temperature measuring, improve the quality of powdered carbon；By setting of steam recovery unit
Setting high effect utilizes heat energy to be dried biomass material, improves energy utilization rate.
The invention is not limited in above-mentioned embodiment, if to the various changes of the present invention or deformation without departing from the spirit of the present invention
And scope, if within the scope of these are changed and deform claim and the equivalent technologies belonging to the present invention, then the present invention is also intended to
Comprise these to change and deformation.
