Cracking organics, biomass are produced the hydrocarbon fuel system
Technical field
The utility model discloses a kind of cracking organics matter, biomass are produced the hydrocarbon fuel system, belongs to organism, biomass energy transformation technology field.
Background technology
The organism that the utility model relates to comprises: fossil oils such as coal, coal gangue, resinous shale, chemical materialss such as waste or used plastics, rubber, biomass comprise crop material, timber wood chip, grass, etc. agriculture and forestry organic waste material, animal bone skin etc.Organism, biomass through pyrolysis liquefaction technology are the cutting edge technologies of the present research and development of biomass energy in the world.This technology can will be high-grade easy storage, easily transportation with the mode of production of successive technology and batch production based on the Wood Adhesives from Biomass of wood chip the like waste, energy density is high and substituted liquid fluid fuel (bio oil) easy to use, it not only can be directly used in the burning of equipment such as existing boiler and gas turbine, and can make the quality of the quality of liquid fuel by further modification refinement processing near fuel powered by conventional energy such as diesel oil or gasoline, can therefrom extract Chemicals in addition with commercial value.
In the various technologies of organism, biomass through pyrolysis liquefaction, exist multiple different testing apparatus and technological line, to reach the purpose that increases the bio oil productive rate and improve the energy utilization level.As quick cracking, hydrocracking, vacuum cracking, low temperature pyrolyzer, partial combustion cracking etc., produce the most economic method of liquid fuel with being cracked into fast under the normal pressure, 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 Fwente university etc. is typically arranged; The equipment scale of described reactor is comparatively huge, and mechanical contact is worn and torn severe and made operation expense also higher simultaneously, therefore will be restricted in mass-producing is used.
The utility model content
The utility model discloses a kind of cracking organics, biomass are produced the hydrocarbon fuel system, has overcome in existing organism, the biomass through pyrolysis liquefaction process that energy utilization rate is not high, energy consumption is big and shortcoming such as not classification of product liquid.
The technical solution adopted in the utility model is: by material-pulverizing device, material preheater, the caloic well heater, cracking reactor, the gas-liquid fractionator, fuel segregation device and corresponding transporting mechanism constitute, wherein, cracking reactor is the interlayer tank body of sealing, interlayer mechanism is connected with gas thermal cycling heating system, the top of cracking reactor is respectively equipped with caloic dog-house and material dog-house, the bottom is provided with fuel discharge outlet, the material whipping appts is installed in it, the caloic shredding unit is connected with the caloic dog-house of cracking reactor by transporting mechanism, the top that the discharge nozzle of scission reaction gas is located at cracking reactor is communicated with the gas-liquid fractionator, inflammable gas and liquid fuel are carried out gas-liquid separation, the gas delivery port of gas-liquid fractionator connects gas concentration unit or feeds back to the caloic well heater provides thermal source, the bottom of gas-liquid fractionator is provided with liquid fuel and reclaims mouth with the hydrocarbon fuel collection of producing, the fuel discharge outlet of cracking reactor bottom connects the fuel segregation device, by screening quartz sand is separated with solid fuel, heat conduction matter turns back to recycle in the caloic well heater once more through the transmission rig of its outlet, and solid fuel is discharged by the discharge port of fuel segregation device bottom and collected.
Transmission rig between described each device of native system adopts closed screw feeder structure for conveying.
Heat conduction matter comprises: quartz sand, silicon carbide, black silicon carbide, aluminium sesquioxide etc.
Native system is with the positively effect that pre-existing reactors equipment is compared: physical construction is simple, making full use of heat conduction matter solid phase conducts heat strong and advantage such as heat flow rate per unit area is big, realize the flash intensification of organism, biomass and separating out fast of fugitive constituent, inflammable gas is fed back to material preheater, caloic well heater carry out recirculation and recycle, thereby reduced the cost of extra source of the gas.
