Gasifying biomass is produced the biomass energy thermochemistry transform mode that combustion gas is a kind of advanced person, and wherein, the gasification of biomass air-water vapor is that a kind of investment is relatively low, and the aerogenesis quality is gasification process preferably also.In this gasification, the needed heat of steam reformation can be supplied with by the partial combustion of air.But this gasification mode is not used widely, and reason is that water vapor adding point is too concentrated, makes water vapor incomplete with mixing of reactant; Cause reaction insufficient; The output capacity of the biological fuel gas that finally causes preparing is low, and calorific value is also low, can't heavy industrialization.The combustion technology of air-water vapor gasifier mainly is that the fire grate grate firing burns and fluidized bed combustion, and wherein, adopting the shortcoming of fire grate grate firing technology is that fuel combustion is incomplete, and excess air ratio is higher, causes thermo-efficiency on the low side; The person as adopting fluid-bed combustion furnace, generally is to be applied to large-sized boiler in addition, and its investment is huge, and production cost is high, can not in medium-sized and small enterprises, try hard to recommend application greatly.
The utility model content
In order to solve the problem that prior art exists, the utility model provides a kind of can prepare high heating value, gasifier that factor of created gase is high.
In order to realize above purpose, the technical scheme of the utility model is following: a kind of biomass Cyclonic air-water vapor gasifier, and it is by housing; Thermal insulation layer is formed, and thermal insulation layer is the hollow circle tube inner-cavity structure, and inner chamber is as the combustion chamber and have the air outlet; The combustion chamber is communicated with a feed-pipe; This feed-pipe inwall (axially) is tangent with combustion chamber inwall (xsect), and said combustion chamber offers at least one through hole and is communicated with the water vapor pipeline, and through-hole wall and combustion chamber inwall are tangent; Water vapor is participated in gasification reaction, calorific value biological fuel gas in preparing by the reactant that produces with the biomass fuel thermal decomposition burning in the input combustion chamber, through hole tangential.
Further, said through hole has two, and the steam port that goes out of each through hole is in different positions in the combustion chamber.
The inlet of said water vapor pipeline connects the water vapor divider, and the water vapor divider is evenly distributed to water vapor in the water vapor pipeline of every road.
Said water vapor divider connects the water vapor house steward.
Said every road water vapor pipeline is equipped with stopping valve.
Said every road water vapor pipeline is equipped with tensimeter.
Said water vapor house steward installs reducing valve, under meter and tensimeter.
Said water vapor divider connects water discharge valve, like drain valve.
Said air outlet sets out tracheae, and its transverse strands is located at the center of combustion chamber and the one of which end is positioned at the combustion chamber and the other end stretches out in outside the combustion chamber.
Compared with prior art, because water vapor is that the tangential is input in the combustion chamber, guarantee that the reactant that produces with the biomass pyrolytic burning carries out thorough mixing, the calorific value of the biological fuel gas behind the gasification reaction is higher, brings up to 1800～2000Kcal/N m
3, improving 30～40%, output capacity improves 20%.
In addition, in the combustion processes of gasifier, the biomass fuel of heat energy source in gasifier that gasification reaction is required realized autothermal equilibrium.Water vapor is input in the combustion chamber of gasifier by multichannel water vapor pipeline; Import water vapor with discrete form from different positions; Make and the internal reaction thing that burns (gas that biomass carbon and pyrolysis and combustion produce) thorough mixing, further gasification reaction reaches purpose more completely.
