Segmented gasification principle of the present invention is such, solid part has gravity decline inertia, gas part has the flowing property of extending in all direction, stove tube 6 band gas port conical cap 9 are less in the vapourizing furnace I, gas part can go out from gas port on the interior stove tube 6, solid part can not be gone into from interior stove tube 6 band gas port conical cap 9 gas ports, can only descend from gravity between stove tube 6 in the vapourizing furnace I and the outer furnace tube 7, go into interior stove tube 6 from interior stove tube 6 material guide holes 5, appearance is filled by induced draft fan 14 active suction high temperature gas flows in interior stove tube 6 spaces of band gas port conical cap more than 9, the hot destructive distillation of high temperature gas flow heated drying of being risen of the space material of interior stove tube more than 6 becomes the gentle fraction of solid carbon part, whereabouts solid carbon part is risen from interior stove tube 6 material guide holes and is compiled hot gas and change into difficult gasification solid part and gasification part from the gas port of the interior stove tube 6 gas port conical cap 9 two strands of high temperature gas flows that come out to descend between interior stove tube 6 and the outer furnace tube 7, thereby produce hot destructive distillation, the complete separate process of hot gasization, hot destructive distillation, the complete separate process of hot gasization is to finish automatically in the body of heater, and Flow of Goods and Materials is simply smooth.
Cyclone bed combustion principle of the present invention is such, conical funnel shape cloth wind furnace bridge 4 cloth wind are used in invention, conical funnel columnar structure makes material compile the whereabouts automatically, conical funnel shape cone surface air guide duct horizontal direction and cone surface medial surface level are tangent, air-flow enters circular cone medial surface automatic horizontal and rotatablely moves, collide with the vertical whereabouts material that compiles, in air guide duct level under the air-flow effect, material pneumatic forms and mixes eddy flow recycle fluidized bed, under ignition conditions, form the cyclone bed burning, the cyclone bed burning has eddy flow and compiles flame, the flame temperature height, the material burning is complete, and oxygen combustion is complete, few with amount of oxygen, eddy flow compiles characteristics and advantages such as deslagging automatically simultaneously.
A gasify part high clean principle of the present invention is such, in the biomass thermal chemistry gasification, initial biomass ortho states material composition is the most complicated, the gas fraction composition that therefore generation of thermal evaporation thermo-cracking change procedure takes place when low temperature is the most complicated impure maximum, during opposite high temperature the thermal reduction change procedure taking place is charcoal part hot gasization that the ortho states material is converted into homogeneous, and the composition of generation is the hydrogen and the carbonic oxide of single cleaning.The present invention thermal evaporation thermo-cracking change procedure produces during with low temperature cooling of gas fraction and burning, make gas fraction impurity all be converted into simple carbonic acid gas, water vapour and as the high temperature gasification agent utilization, the big gas fraction of the complicated impurity level of composition does not exist, is the inorganic states small molecules such as hydrogen, carbonic oxide of single cleaning like this in gasification part.High-temperature flue gas is that the charcoal layer has filtered the dust that the power wind is raised, and has reduced the combustible gas dust content significantly by the gasification of charcoal layer simultaneously, so gained gasification part is high clean gas.
The present invention's part principle of high energy value that gasifies is such, and invention contains the maximum gas fraction of cold state water vapor and is cooled by gas fraction, a gasification part cooling heat transferring, cold state vapour content minimizing in water vapor removals of being condensed, gasification part; By with oxygenous vaporized chemical pre-heating temperature elevation, to reduce based on consumption behind the oxygenous vaporized chemical pre-heating temperature elevation of air, a nitrogen content reduces in gasification part; By containing the gas fraction burning of low heat value composition, reduced the low heat value composition; Device burns with cyclone bed, and the combustion flame temperature height produces the high-temperature flue-gas height, and carbonic acid gas, water vapor and charcoal can fully react and produce high energy value hydrogen and carbonic oxide; Installing gasification part mainly is to change with carbon heat reducing to obtain, and a nitrogen content is low in gasification part like this, and vapour content is low, and carbon dioxide content is low, and hydrogen and carbonic oxide content height are so calorific value is big.
