Description
Technical field
The present invention relates to a kind of continuous biomass pyrolysis device, be meant a kind of continuous biomass pyrolysis device that has spring feed appliance and reduction of speed air outlet especially.
Background technology
Biomass energy is after fossil energies such as oil, coal, Sweet natural gas, the current global the fourth-largest energy, China's biomass resource is abundant, the various parts of having utilized of biomass deduction such as the annual agricultural crop straw of producing, cereal shell skin, still there are the biomass that are equivalent to hundred million tons of standard coals of 2-2.5 to wait to develop, forestry abandoned biomass resource has 3700 ten thousand steres every year approximately, is equivalent to 2,000 ten thousand tons of standard coals.In addition, China's cities and towns organic waste biomass resource of being equivalent to 200,000,000 tons of standard coals every year in addition has pending and development and use.Mode of biomass energy utilization is more, wherein in biomass thermal chemical transformation technology, because pyrolysis can directly obtain charcoal, liquid state and gaseous product and more and more be subjected to people's attention.
Chinese patent ZL, 00263035.4, a kind of shell and tube moving-bed continuous carbonization method for pyrolysis has been proposed.It is characterized in that: the pyrolysis combustion gas that carbonizing zone produces is passed through the bed of material with raw material adverse current or cross-flow from bottom to top, discharges from the top at last and enters condenser system, and bio oil is separated with not condensing combustion gas; Calcining zone in stove controlledly imports the gas fuel burning that air is emitted carbonization process from the outside, the high-temperature gas heating bed of generation makes calcining temperature reach 700～1100 ℃; Move down gradually and carry out indirect heat exchange along cooling duct at the cooling zone charcoal, do not reduce to and can take out after the temperature of spontaneous combustion with heat-eliminating medium.The deficiency of this method is that the air capacity that calcining enters the time in the wood vinegar is wayward, may make the charcoal calcining excessive or insufficient.
Patent ZL, 200620135129.4, a kind of closed biomass dry distillation charring gasification installation that stir-fries has continuously been proposed.Its characteristics are: be provided with spiral pushing device on dry distillation carbonization bed, be communicated with the combustion chamber between the dry distillation carbonization bed outer shell.The retainer cross section of dry distillation carbonization bed is circular-arc, and each dry distillation carbonization bed axially parallel is arranged, and its end face structure is rectangular and arranges.The spiral flood dragon plate of spiral pushing device is the shovel board shape, and distributes along section between the hand of spiral.The charcoal material is effectively advanced in the destructive distillation that evenly stir-fries, realize the charing of each layer dry distillation carbonization bed sealing anoxic.But the shortcoming of this technology is: material will could be discharged through twice commutation in reactor during dry distillation charring, causes mechanism's complexity, the transmission complexity of device, system's dismounting difficulty that in a single day goes wrong; Induced draft fan is directly extracted flue gas out, easily fine particle is taken out of, causes escape pipe to stop up; Reactor is by the automatic gas-producing combustion heat supplying, and the difficult control of temperature when aerogenesis is inhomogeneous in the dry distillation carbonization bed, variation of temperature will cause producing the charcoal streaking.
Patent day spy opens 2001-131562 and has proposed a kind of tubular type charring furnace, its charring furnace is the long straight tube of a traverse, the high-temperature flue gas that utilizes roasting kiln to produce during destructive distillation carries out outer heating to long straight tube, raw material by hopper to the charring furnace feed, feed end at charring furnace has air inlet port, rare gas element enters in the charring furnace by this pore during destructive distillation, the one side of charing on one side terminad under the effect of strength moved after material entered charring furnace, the carbonizing tube end is connected to condensing works, after charing finished, solid carbon was after cooling off outside the vent pipe.Advantage is that charring furnace is simple in structure, and shortcoming is that the speed that material moves should not be controlled, and causes the charing inequality easily.
Summary of the invention
