Description
Technical field
The utility model relates to a kind of filter, relates in particular to a kind of gas-solid separating device that is used for the biomass energy converting system.
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, the short gas phase time of staying, simple and direct temperature control, charcoal recovery easily, lower investment and ripe method for designing.
