Description
Technical field
The present invention relates to a kind of living beings filter material filter, relate in particular to a kind of filter that is used for system for rapidly pyrolysing and liquefying biomass.
Background technology
Along with the continuous development of World Economics, the energy and environmental problem become increasingly conspicuous.The human main energy sources of using at present has 3 kinds of oil, natural gas and coals.According to International Energy Agency statistics, on the earth these 3 kinds of energy for time limits of human exploitation have only 40 years respectively, 50 years and 240 years.Tap a new source of energy and become to concern the key subjects of human social.
Biomass energy is the solar energy that is stored in by the photosynthesis of plant and solar energy in the plant.According to estimates, the annual energy of storing of plant is equivalent to 10 times that world's main fuel consumes, and is less than 1% of its total amount as the utilization of the energy.By the biomass energy switch technology, can utilize biomass energy efficiently, produce various clean fuels, substitute fuel such as coal, oil and natural gas.
At present, countries in the world, especially developed country all are being devoted to develop efficient, free of contamination biomass energy utilization technologies, to reach the protection mineral resources, ensure energy security, realize CO
2Reduce discharging, promote sustainable economic and social development.Biomass energy will become the future source of energy important component part, and the expert estimates that global total energy consumption in 2015 will have 40% from biomass energy, and mainly the industrialized development by biomass power generation and biomass liquid fuel realizes.
At present, changing living beings into liquid fuel (bio oil) by the high temperature fast pyrogenation is to realize one of efficient important channel that utilizes of biomass energy.According to the heat transfer type difference, the biomass through pyrolysis liquefaction process generally can be divided into 3 classes: (1) wall indirect heating type reactor.It mainly contacts with living beings by scorching hot reactor surface, thereby being delivered to living beings, heat it is rapidly heated reach fast pyrolysis, as the rotation awl biomass through pyrolysis to-oil reactor of the heat of ablation cracking reactor of Britain Aston university, Vortex reactor that NREL proposes and the design of Dutch Twente university etc.; (2) radiation heat transfer formula reactor, the principal character of this class reactor are to provide biomass through pyrolysis required heat by the surface of a high temperature or thermal source, and it mainly carries out the heat transmission by heat radiation, as the heat radiation reactor of U.S. Washington university; (3) gas-solid mixing direct-heating type reactor, it mainly is by thermal current or Dual-Phrase Distribution of Gas olid living beings to be carried out Fast Heating, it can provide the high rate of heat addition and uniform relatively reaction temperature, the carrier gas of flowing simultaneously fast is convenient to product of thermal cracking and is in time separated out, as the fluid bed heat cracking system of Canadian Waterloo university, circulating fluid bed reactor that Canadian Ensyn proposes and the quick flow type pump with injection reactor of GTFJ etc.The equipment scale of wall indirect heating type reactor is comparatively huge, and simultaneously mechanical contact wear is severe and make operation expense also higher, therefore will be restricted in scale is used, and this type of reactor is general main to provide the mechanism test required.And radiation recuperator heat exchange effect is relatively poor, and energy consumption is difficult to scale greatly.Than preceding two types, abroad developed and the biomass through pyrolysis liquefaction reaction device side of attempting scale overweights the 3rd class.Fluid bed (or recirculating fluidized bed) pyrolysis liquefaction technology makes it become the technology that the thermal cracking that development potentiality is arranged is at present most produced liquid fuel because of realizing the high rate of heat addition, short gas residence time, simple and direct temperature control, charcoal recovery easily, lower investment and ripe method for designing.
The process and the double tower apparatus system thereof of a kind of biomass pyrolysis liquefaction that is disclosed for CN200510057215.8 number as Chinese patent.Its process comprises biological material sent into allows high-temperature stream gasification and heating medium for high temperature mix with biological material living beings are carried out the step of thermal cracking in the pyrolytic reaction tower, in separator, pyrolysis gas and carbon residue, ash are carried out the step of gas solid separation, and the step of bio oil etc. of in condenser, pyrolysis air cooling being congealed into.Wherein, thermophore is exported the circulatory system with pyrolysis gas, carbon residue etc. in the pyrolytic reaction tower; Carbon residue is used to thermophore is preheated.Its apparatus system also comprises the thermophore separator that thermophore-waste gas-ash content that thermophore and carbon residue are separated the thermophore heating tower of once initial separator, burning carbon residue earlier and be used for coming out in the thermophore heating tower with other materials together separates.But, as can be seen from the above description, the CN200510057215.8 patent has following weak point: incondensable gas that comes out from condenser and carrier gas are as reclaiming gas, directly be recycled a part of fluidized gas as the pyrolytic reaction tower, the combustion-supporting gas of thermophore heating tower's a part, and a part of cycling hot carrier gas in the feed mechanism, therefore, on the one hand, the incondensable gas that can be used as gaseous fuel does not have to form the fuel gas product that can carry to the external world, this has caused Value Loss, on the other hand, contain a large amount of moisture and tar in the recovery gas of this mixing, yet but just be not directly used in follow-up flow process, cause vicious circle, not only cause the biomass energy conversion ratio to reduce through abundant processing, but also will cause device damage, even security incident takes place.
Therefore, provide a kind of and change conveniently, the decoking filter that is used for system for rapidly pyrolysing and liquefying biomass simple in structure, cheap, clean environment firendly becomes urgent problem.
Summary of the invention
