Chinese patent application numbers 201220188346.5 discloses a kind of " whirlwind-type biomass fluid bed gasification furnace ", in the vapourizing furnace bottom ash discharge chamber and burning chamber is arranged; By the some groups of reaction members of being made up of a stone or metal plate for standing a stove on as a precaution against fire and polylith spinning disk, coil pipe superheater and gas outlet are arranged at the top in combined reaction chamber in the combined reaction chamber in stage casing; There is inner core in centre at the vapourizing furnace inner chamber, and there is the awl of distribution the below of interior nozzle, and the hopper of spiral propeller is arranged in the top connects, and spinning disk is fixedly mounted on the outer wall of inner core with certain inclination angle; The body of heater side has fuel gas return-flow inlet pipe, many superheated vapour inlet pipe and Duo Gen thermometric to take over.
Chinese patent application 200420024372.X discloses a kind of " biomass gasifying furnace ", be that a kind of no tar produces, and technology is simple, can produce the biomass of high heating value gas and the vapourizing furnace that coal mixes.It is gasified raw material with biomass, two kinds of materials of coal, the discontinuous operation that fluidized-bed gasification furnace adopts the air feed burning and gasifies for steam; At the air feed combustion phases, coal supply and air feed are gone in the stove, and the coal charge of vapourizing furnace is burnt under fluidized state, emit heat; At gasifying stage, feed water vapour and biomass to vapourizing furnace, make the pyrocarbon bed of material issue the destructive distillation pyrolytic gasification reaction at high temperature of the reaction of unboiled water coal gas, biomass in fluidized state, the high heating value gas that produces enters gas cleaning system after the cooling dust removal process; It has given prominence to biomass volatile matter height, and fixed carbon is few, is easy to the high temperature carbonization pyrolysis, and coal fixed carbon height, the ash fusion point height, being easy to burn forms the advantage of high warm material layer, organically merges the fuel gas that can produce the high heating value that does not contain tar by the two.
Prior biological matter vapourizing furnace is the secondary reaction that satisfies wood gas, generally all the dilute phase section is superimposed upon close phase section top, and coal gas is discharged from the top of dilute phase section after entering dilute phase section continuation reaction from close phase section.So, biomass fluid bedly all design taller and biglyyer.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of biomass gasifying furnace that can effectively reduce vapourizing furnace height and cost of manufacture is provided.
Biomass gasifying furnace described in the utility model is made up of feed bin, dilute phase section, close phase section, blast pipe, scum pipe, fly-ash separator and gas exit, feed bin is communicated with the bottom of close phase section by the feed auger of its bottom, the top of close phase section is open state, the bottom is provided with blast pipe and scum pipe, the dilute phase section is sleeved on the close phase section, gas exit is positioned at the bottom of dilute phase section, is provided with unloading valve in the bottom of dilute phase section; Outer wall in dilute phase section and close section mutually has refractory materials.
The utility model arranges equal air compartment and air distribution plate between blast pipe and close phase section, make air intake even.
The utility model has adopted the dilute phase section has been sleeved on close phase section outside, and gas exit is arranged on the technical pattern of dilute phase pars infrasegmentalis, under the prerequisite that guarantees reaction compartment, can effectively reduce the height of vapourizing furnace, and can reduce the cost of manufacture of vapourizing furnace.Simultaneously, said structure makes the low flow velocity of dilute phase section and coal gas discharge from the bottom of dilute phase section from top to down, principle according to gravitational dust collection, under the situation that does not increase resistance, can remove the bigger dust of particle diameter, reduce the dust concentration of discharged producer gas, alleviate the burden of follow-up fly-ash separator, reduce the wearing and tearing of fly-ash separator.
The utility model is with biomass material process gasification reaction approach, produces wood gas, powdered carbon.Structurally cancelled material returning valve, the carbon dust that separates does not return and continues gasification in the stove, but the carbon dust of discharging is added the utilization of compressed with adhesive forming charcoal, and the economic worth of type charcoal, much larger than carbon dust being returned the economic worth that continues gasification in the stove.Structure can effectively reduce the height of vapourizing furnace cleverly simultaneously, and can reduce the cost of manufacture of vapourizing furnace.
