Detailed description of the invention
Fig. 1 is gasification of biomass process flow chart of the invention.
Fig. 2 is the schematic diagram of fixed-bed gasification furnace of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of biomass gasification device, including fixed-bed gasification furnace, and be arranged in fixed-bed gasification furnace one The feed device at end, and the cyclone dust collectors of the fixed-bed gasification furnace other end are set, and are arranged in fixed-bed gasification furnace lower end The first air blower;The feed device includes the feeder for conveying biomass, and connect with feeder, for that will give birth to The bucket elevator that substance is lifted up, and the feed auger being arranged between bucket elevator and fixed-bed gasification furnace.The cyclone dust removal The device other end is connected with high-temperature blower, and high-temperature blower, which can form very big suction biomass gasification burning is drawn into whirlwind, to be removed Dirt device is separated, and the high-temperature blower is connected with moushroom valve by a gas pipeline, and moushroom valve is connected with combustion by a gas pipeline Burner, burner are connected with the boiler for generating steam;The burner is also connected with reserve fuel system.The boiler and burning The second air blower is provided between device.The boiler is also connected with economizer, and air-introduced machine is provided between economizer and boiler, draws Blower is connected with chimney.
A kind of biomass gasification method, comprising the following steps: biomass solid waste is via feeder → bucket elevator → charging spiral shell Rotation enters fixed-bed gasification furnace by top, and gasifying medium blasts fixed-bed gasification furnace by the first air blower, makees in gasifying medium Under, biomass generates biomass gasification burning through drying, pyrolysis, oxidation, reduction process in fixed-bed gasification furnace, from gasification The discharge of furnace top-side, under high-temperature blower effect, combustion gas is conveyed after cyclone dust collectors high temperature purification dedusting by gas pipeline To burner, biomass gasification burning and combustion air, to boiler, generate steam through burner mixing after-combustion heat supply.In this reality It applies in example, the gasifying medium is air.
Wherein, as shown in Fig. 2, fixed-bed gasification furnace working principle:
Gasification of biomass is under gasifying agent existence condition, and the hydrocarbon for forming biomass is converted into fuel gas Process.Gasification of biomass generally undergoes following several stages:
1. drying process: after reactor is added in biomass material, being initially heated, moisture contained by biomass is precipitated.
2. pyrolytic process: when temperature rises to 200~250 DEG C, thermal decomposition, the carbon of macromolecular takes place in biomass components The chain of hydrogen compound is broken, and the volatile matter of biomass is precipitated.It leaves carbon residue and ash constitutes the bed further reflected.Pyrolysis Process is an extremely complex physical and chemical process, with the rate of heat addition, temperature and pyrolysis atmosphere difference, the difference of thermal decomposition product It is very not big.
3. combustion process: in the gasification for thering is oxygen (or air) to participate in, oxygen and pyrogenous origin volatile matter and Combustion reaction occurs for carbon residue, releases heat to maintain pyrolytic process and reduction reaction institute calorific requirement.
4. reduction reaction: reduction reaction occurs mainly between water vapour and carbon dioxide and carbon after burning, by also Original reaction, carbon are further converted to the fuel gas such as carbon monoxide and methane.Reduction reaction is the endothermic reaction, and temperature gets over Gao Yueyou Conducive to reduction reaction progress.
Experimental example;
The main environmental protection index of combustion gas
Biomass gasification fired technique for applying, SO2, NOx, soot emissions etc. will be better than fuel oil, close to natural gas discharge Standard.The discharge expectation index of gasification, and combustion should be better than light oil.Following table is biomass burning combustion gas and other fuel atmosphere pollution The data of object discharge:
Boiler combustion biomass gasification burning has apparent price advantage compared with conventional fuel heat supply.It is natural with using Gas saves fuel cost 36% compared to fuel cost 24% is saved compared with diesel oil, and fuel cost 21% is saved compared with heavy oil. Biomass gasification burning is compared as follows with other fuel costs:
Successful case:
It burns natural gas (calorific value 8000);Day air consumption: 12 bottles of 768 cubes of (50kg/ bottles) 50 × 12 × 1.28 ≈;Cost: 250 yuan/bottle=3000 yuan/day;(being free of the artificial electricity charge)
Gasification, and combustion (calorific value 3600~4000);Day air consumption: about 3 tons of leftover pieces (1kg leftover pieces produce 2 cubes of gas) 3000 × 2=6000 cubes;Cost: being then 0 yuan/day if it is own biomass solid waste;If 450 yuan/ton of waste material purchase price, About 1350 yuan/day (are free of the artificial electricity charge)
By comparison it is found that the cost of biomass gasification burning of the invention is significantly lower than natural gas.
The present invention provides a kind of biomass gasification device and methods, have the advantages that
The main source of biomass energy has fuel wood, wood wastes, agricultural stalk, excrement of animals, sugaring crop waste residue, city City's rubbish and sewage, water plant etc..Biomass solid waste or petrochemical industry class byproduct such as cloth waste material are carried out gasification process, then The combustible gas for using processing to generate fuel as needed for producing, reaches the requirement of environmental protection, had both avoided the high cost using natural gas Puzzlement, and solve waste problems.For example, the leftover pieces of wood-working factory, cloth waste material of clothing factory etc..
The above are merely the preferred embodiment of the present invention, it is noted that for those skilled in the art, not Under the premise of being detached from present inventive concept, several modifications and improvements can also be made, these also should be considered as protection model of the invention It encloses, these all will not influence the effect and patent practicability that the present invention is implemented.
