Description

A kind of miniature movable type agricultural and forest biomass fast pyrolysis device
Technical field
The present invention relates to a kind of miniature movable type agricultural and forest biomass fast pyrolysis device, belong to the agricultural-forestry biomass utilization, especially the recovery energy field.
Background technology
Agricultural and forest biomass fast pyrolysis is meant under the anoxybiotic condition, with the agricultural-forestry biomass Pintsch process is gas and solid carbon, the cracked gas that to remove solid carbon afterwards again cools off the process that obtains bio oil and non-condensable gases rapidly, its principal product is a bio oil, and by product is solid carbon and non-condensable gases.Agricultural and forest biomass fast pyrolysis must satisfy three primary conditions: medium thermo-cracking temperature (450~650 ), higher biological particles temperature rise rate (10 2~10 4K/s) and short gas residence time (0.2~3s).
The agricultural-forestry biomass resource distribution relatively disperses, need carry out thermo-cracking from collecting and transport to factory vegetatively, and agricultural-forestry biomass---especially agricultural wastes (as stalk, rice husk etc.) energy density is low, therefore need to collect, transport, store the raw material supply of a large amount of raw materials when satisfying continuous production, and plant size is big more, it is big more that raw material is collected radius, and raw material is collected, trucking costs is high more.WIPO PCT patent (WO2006/117006A1) discloses a kind of mobile biomass pyrolysis installation, this device comprises biomass through pyrolysis unit and travel mechanism, can haul scattered biomass concentration point by tow tractor and carry out the thermo-cracking processing, having reduced raw material collects and transportation cost, but the pyrolysis reactor that this pyrolysis plant adopts is a kind of centrifugal ablation reactor, belong to the direct contact reactor of mechanical movement formula, be characterized in to use the raw material (2~6mm) of greater particle size, need not use heat-transfer medium and assist gas, but in its reactor moving parts is arranged, structure is relatively complicated, the moving parts of equipment breaks down easily under thermo-cracking high temperature, and working reliability and operation life are difficult to be guaranteed.Chinese invention patent (CN200510137.7) discloses a kind of mobile biomass liquefaction system, its equipment all can be delivered by transportation means such as automobiles, carry out biomass liquefying than being easier to transport scattered biomass concentration point to, can reduce raw material equally collects and trucking costs, but the reactor that this system adopts is the normal flow fluidized bed reactor, and need to dismantle, transport and reinstall debugging in new grown place when changeing factory, therefore changeing factory's cycle can be long.
Prior biological matter rapid pyrolysis reactor mainly contains fluidized bed reactor (mainly comprising fluidized-bed, spouted bed, circulating fluidized bed, spouted fluidized bed etc.) and mechanical movement formula reactor (mainly comprising rotation awl, moving-bed, vacuum bed, ablation reactor etc.), and wherein fluidized bed reactor is the main both at home and abroad at present agricultural and forest biomass fast pyrolysis reactor that adopts.Yet up to the present yet there are some problems in fluidized bed reactor, has the bed material problem that horizontal mixed effect is undesirable, heat transfer efficiency is not high such as the normal flow fluidized bed reactor; Spouted bed bioreactor is prone to problems such as dead band, fluctuation of service; Circulating fluidized bed needs the fluidal texture of additional designs bed material and the volume that seems is bigger, and its thermo-efficiency is lower when using on a large scale; Though spouted fluidized bed combines the advantage of spouted bed and fluidized-bed, but still need design spouted gas and fluidized gas air flue respectively, still need the spouted gas and the fluidized gas source of the gas that provide extra respectively, therefore also have device structure complexity, working cost problem of higher.Therefore we have applied for utility model patent (ZL 2007201519336), a kind of spouted fluidized bed bioreactor is disclosed, by the design of tabular air distribution plate, will be divided into spouted gas and fluidized gas by the gas of same source of the gas supply, structure of reactor is simplified; Simultaneously, this system uses the not condensable gases that produces behind the biomass through pyrolysis as described spouted gas and fluidized gas, has avoided using extra spouted gas and fluidized gas source of the gas, has reduced running cost.But yet there are some imperfection parts in this utility model, at first, owing to comprise impurity such as tar, powdered carbon in the not condensable gases that biomass through pyrolysis produces, so use the not condensable gases circulation after the cracking to cause the pipeline (comprising blower fan, valve, under meter etc.) of its process to stop up through regular meeting because of the alluvial of tar and powdered carbon as source of the gas, equipment continous-stable service ability is not good enough; Secondly, the extra source of the gas that not condensable gases after the use cracking replaces stability of flow causes the fluctuation of air-flow in the reactor easily as spouted gas and fluidized gas, and reactor fluidised form difficult quality is guaranteed, carry out to such an extent as to influence the continous-stable of heat scission reaction, the bio oil productive rate is lower.
In addition, the problem that prior art is amplified difficulty for the fluidized bed reactor industrialization also is not well solved, the production of difficult realization large-scale industrialization.
In the agricultural and forestry biomass fast pyrogenation process,, generally need regulate processing parameter (mainly comprising inlet amount, fluidizing gas velocity, bed material amount and thermo-cracking temperature etc.) according to feedstock property and reactor size in order to satisfy three primary conditions.Because the agricultural-forestry biomass resource is of a great variety, character is different, for raw material of different nature, same reactor is difficult to satisfy simultaneously by the adjusting processing parameter these three primary conditions of fast pyrolysis, and the bigger change of processing parameter also can influence the serviceability of other link of complete assembly, and therefore same set of fast pyrolysis device is difficult to be applicable to the fast pyrolysis of multiple different properties agricultural-forestry biomass raw material.If the reactor that adopts size to regulate at raw material of different nature, by conditioned reaction device size, be aided with the adjusting of processing parameter again, will be easy to satisfy three primary conditions of fast pyrolysis, thereby make complete assembly be applicable to plurality of raw materials.
