Temperature is promoted, and the Main change of the biomass in first order reaction kettle 28 is: in the room temperature~150 DEG C stage, biomass dehydration；In
In 150~240 DEG C of temperature, the part glucose in cellulose macromolecule in biomass starts to be dehydrated, all kinds of in biomass to wave
It sends out object to be precipitated, biggish mass loss occurs for biomass material；Although biomass itself reaches ignition point, due to anoxic ring
Border can not burn, and can not generate gas phase flame；In 240~400 DEG C of temperature, glycosidic bond, the part carbon oxygen of glucose
And carbon-carbon bond starts to be broken, and generates new low molecular weight volatile compound；
(5) biomass is delivered in second order reaction kettle 33 by the second auger conveyor 29 of starting；
(6) first rotating shaft 9, arch agitating roller 10 and the blanking revolving fragment 11 persistently rotated is quantitative defeated downwards by biomass
It send, biomass stacks on third butterfly plate 7；At the same time, the electric hot plate 15 at 7 back side of third butterfly plate constantly generates heat, heat
Constantly be communicated up by stratobios matter material, formed in third-order reaction kettle 1 and second order reaction kettle 33 from the bottom to top temperature by
The temperature layer gradually reduced；
(7) in different temperature layers different variations, In occur for the biomass in second order reaction kettle 33 and third-order reaction kettle 1
In 150~240 DEG C of temperature, the part glucose in cellulose macromolecule in biomass starts to be dehydrated, all kinds of in biomass to wave
It sends out object to be precipitated, biggish mass loss occurs for biomass material；Although biomass itself reaches ignition point, due to anoxic ring
Border can not burn, and can not generate gas phase flame；In 240~400 DEG C of temperature, glycosidic bond, the part carbon oxygen of glucose
And carbon-carbon bond starts to be broken, and generates new low molecular weight volatile compound；Under 400 DEG C or more of temperature environment, cellulose
The nubbin progress of macromolecular is aromatic ring, gradually forms graphite-structure, ultimately forms charcoal；
(8) charcoal is fallen into hollow screw conveyer 8, forms layer of charcoal；
(9) it is located at the fever pipeline 13 in hollow screw conveyer 8 and heats layer of charcoal to 1050 DEG C or more；
(10) when close with feeding chamber pressure in first order reaction kettle 28, second order reaction kettle 33 and third-order reaction kettle 1, first
Air extractor starts, and the gas in first order reaction kettle 28, second order reaction kettle 33 and third-order reaction kettle 1 is along hollow screw conveyer
8 and its internal layer of charcoal flowed into gas wash tower 23, second pyrolysis occurs in layer of charcoal for gas；

Blade 25 and its airflow-resistive generated；Upper choked flow blade 26 generates upward air-flow, lower choked flow blade 25 and upper choked flow blade
The metastable area Jing Wen of air-flow is formed between 26, the little particle powdered carbon for having passed through lower choked flow blade 25 can be because certainly in the area Jing Wen
It settles again；Smaller charcoal powder particles continue during further up by upper choked flow blade 26 and its air-flow generated
Blocking；The air-flow for leaving gas wash tower 23 enters horizontal multi-layer bubble deduster 32, and charcoal powder particles are further by horizontal multi-layer water
The clear water stored in deduster 32 is steeped to absorb；
(12) with the effect of hollow screw conveyer 8, charcoal enters row's charcoal pipe 18 by expansion joint 17, shown in figure
The piston rod of first hydraulic cylinder 27 is constantly to left translation charcoal, and by the ponding of left end row's charcoal threeway 19, charcoal is being arranged
It constantly accumulates and is extruded closely knit in charcoal pipe 18；At the same time, coolant liquid is constantly flowed through between row's charcoal pipe 18 and shell 22,
Cool down to charcoal；Coolant liquid guide pin 31 makes coolant liquid, and spirally path is transported between shell 22 and row's charcoal pipe 18
It is dynamic, increase stroke of the coolant liquid between shell 22 and row's charcoal pipe 18, improves the cooling effect of coolant liquid；
(13) when arrange accumulate enough charcoals in charcoal pipe 18 after, open third valve 21, arrange the in charcoal threeway 19
The piston rod of two hydraulic cylinders 20 executes primary row's charcoal movement, and one section of charcoal is discharged；During third valve 21 is opened, keep
The piston rod of first hydraulic cylinder 27 is in extended state, blocks expansion joint 17 using the piston rod of first hydraulic cylinder 27, avoids shadow
Ring the vacuum state in third-order reaction kettle 1.
It will be apparent that the feeding device of the present embodiment continuous biomass apparatus for thermal cleavage and row's charcoal device are independent part
