The invention pertains to the technical field of biomass energy utilization and particularly relates to a device which adopts biomass for preparing gas and comprises a lower furnace door, an ash discharging mouth, an ash bin, a grate, a combustion chamber, a thermal insulation bin, a gas inlet, a storage bin, a feed inlet, a furnace cover, a gas pipe, a gas outlet, a porous medium, an air secondary inlet, an air primary inlet and an air pipe; the cracking type biomass gasifier is characterized in that: a gas primary outlet, the porous medium, the gas pipe and the gas outlet form a gas transmission pipeline which is arranged in the storage bin; the gas transmission pipeline is a U-shaped pipe or a spiral coil; and the porous medium is thermal storage ceramic material or tar catalyst material such as dolomite, olivine, clay ore, charcoal, alkali metal compound, nickel base, etc. When going through a combustion area through the gas pipe, the gas is not mixed and burned with the air in the combustion area, therefore, the difficult technical problem that the air and the gas in the existing down-draft biomass gasifier are easy to be burnt out; and the gas can be heated in the combustion area through the gas pipe, and the tar contained in the gas is further converted through the thermal storage, filtering and catalysis of the porous medium, thus reducing the tar content of the biomass gas, and simultaneously improving the conversion rate and the thermal value of gas.
Description
Technical field:
The invention belongs to the biomass energy utilization technologies field, particularly adopt biomass to prepare the device of combustion gas.
Background technology:
Biomass gasification technology can solve the problem of environmental pollution that the rural energy utilising efficiency is low, the improper disposal of residue stalk causes to a great extent.At present, biomass gasifying furnace has two types of fixed bed, fluidized-beds.Wherein, fixed-bed gasification furnace because of its have simple in structure, make easy, cheap, processing ease, be applicable to advantages such as bulk and macrobead raw material.Fixed-bed gasification furnace mainly contains two kinds of updraft type and downdrafts.For the updraft type vapourizing furnace, it is slow to have an aerogenesis, and the tar of generation is many, burn easily empty, built on stilts, filler shortcoming such as waste time and energy.The existence of tar has many-sided disadvantageous effect to gasification, at first it has reduced gasification efficiency, the energy of coal-tar middle oil product of gasifying generally accounts for 5～15% of total energy, this part energy is to be difficult to be utilized with inflammable gas when low temperature, major part is wasted, and secondly tar is condensed into liquid state when low temperature, and easy and water, coke etc. combine, stifled air duct makes the equipment for gasification operation that difficulty take place.In addition, the tar that is condensed into fine drop is difficult to after-flame than gas, is easy to generate particles such as carbon black when burning, utilizes equipment damage quite serious to combustion gas.So, take way usually: add refining plant at the tar that gasification produces; Or adopt the downdraft vapourizing furnace, and make combustion gas that pyrolysis produces and tar by high temperature combustion zone and reduction zone, make tar cracking under hot conditions, become inflammable gas.Yet the updraft type vapourizing furnace adds refining plant and has caused manufacturing cost to improve relatively.The downdraft vapourizing furnace, because of the combustion gas that produces will be passed through laryngeal structure, simultaneously produce a large amount of gases in this zone, gas flow rate increases, and has solid materials in the passage, and the gas flow resistance increases, consumed power increases, and causing pyrolysis zone pressure to increase, top opening for feed sealing difficulty is easily smoldered; And because of the inflammable gas that generates by the combustion zone, to conditional request harshnesses such as furnace binding design and air distribution, material performances.
Summary of the invention:
In order to overcome present the problems referred to above, the present invention changes the structure of existing fixed bed updraft type and downdraft vapourizing furnace, design a kind of novel updraft type biomass gasifying furnace, when having both the advantage of updraft type and downdraft vapourizing furnace, can effectively reduce the problem that both exist.Cracking type biomass gasifier in tar furnace of the present invention comprises lower furnace door, ash discharging hole, grey storehouse, fire grate, combustion chamber, the insulation storehouse, fuel gas inlet, feed bin, opening for feed, bell, gas pipeline, gas outlet, porous medium, air secondary import, an import of air, air line; Feature is that combustion gas once exports, porous medium, and gas pipeline, gas outlet is formed fuel gas transportation pipeline, is installed in the feed bin; Fuel gas transportation pipeline is U type pipe or spiral pipe; Porous medium is thermal storage ceramic material or rhombspar, peridotites, clay ore, charcoal, alkali metal compound, tar catalystic material such as Ni-based.
The invention has the beneficial effects as follows: because of combustion gas by gas pipeline through the combustion zone, can with the burning of the air mixed of combustion zone, solved the technical barrier that present downdraft is easily grilled thoroughly; And the combustion zone can heat combustion gas by gas pipeline, and the accumulation of heat of porous medium, filtration, katalysis can make the tar that contains in the combustion gas further transform, and have reduced the coal-tar middle oil content of biological fuel gas, have improved transformation efficiency and fuel gases calorific value simultaneously.Cracking type biomass gasifier in tar furnace of the present invention possesses advantages such as transformation efficiency height, aerogenesis is easy, tar content is low.
