Embodiment: the present invention will be further described in conjunction with the accompanying drawings.

Among Fig. 1-3, gasifier provided by the invention mainly comprises the gas producer body, parts such as cracking steam tank, vaporizer, fly-ash separator, and upper of furnace body has theloading hopper 1 of charging.Be designed to the through type flue in the body of heater, flameretardant coating 16 is arranged in the body of heater shell.Stoverod plate 9 is arranged at the flue bottom, and the stove rod plate bottom is connected withvaporizer 10, and thevapour pipe 17 of vaporizer is arranged on the inboard wall of furnace body, has the ash output hole that leads to the outside on body of heater one sidewall, opens sealed ash output hole and can remove lime-ash.Spirrillum whirlwind road 18 1 ends of arranging along the vapour pipe inboard connect oxygenenrichment blower fan 11, and the oxygen enrichment blower fan links to each other with body of heater littleback pressure engine 12 outward again.The other end in whirlwind road is connected to above the stove rod plate.Stove rod plate top iscatalyzer storehouse 2, is provided withfire brick layer 13 between the catalyzer storehouse in stove rod plate and stove, plays the effect of not only lowering the temperature but also waste heat being provided.Have a plurality of catalyzer mouths that communicate with the catalyzer storehouse on the furnace body outer wall, catalyzer can join in the catalyzer storehouse by the catalyzer mouth, then is vaporizer above the catalyzer storehouse.

Crackingsteam tank 14 is designed to automatic inlet type and places outside the body of heater, its top has water-in and running water pipe to connect supply cold water, can observe the water level of the inside from the safety level typotron, top is provided withsafety valve 15 simultaneously, and the water vapour output pipe valve of output hot water is arranged at the bottom.At the body of heater middle part sealed sight burner is arranged, can light a fire and remove the gred by this mouthful.

The water vapour output pipe valve of cracking steam tank bottom is communicated with the vapour pipe of vaporizer, water vapour at high temperature forms the pressure that is not less than 1MPa with hydroxide radical (HO) reaction, promote the work of little back pressure engine and drive the oxygen enrichment blower fan, be blown into a large amount of oxygen-enriched combustion-supportings to burner hearth.Water vapour is mixed into vaporized chemical with the oxygen enrichment that the oxygen enrichment blower fan is sent into again, is transported to vaporizer and fuel and continues reaction, so forms circulation, has realized not having the electricity running, increase fuel gasification efficiency, improved the combustion value, improved the output combustion gas quality.

Bell jar fly-ash separator 3 bottoms are connected with the catalyzer storehouse by pipe connecting, and top is communicated to byblast pipe 4 and cuts stream direct currenttornado dust collector 5, cut stream direct current tornado dust collector bottom and are communicated in the body of heater by air outlet tube 6.The bottom of two fly-ash separators has dust-exhausting port 7 to be connected withwater seal 8 respectively.

Working process of the present invention: fuel is added in the stove by loading hopper, light make the normal operation of this gasifier after, little back pressure engine drives the work of oxygen enrichment blower fan, and oxygen enrichment and vaporized chemical are blown into vaporizer and the elementary gas of fuel mix burning generation.Elementary gas enters the bell jar fly-ash separator via the pipeline that places catalyzer Cang Chu and carries out the dust removal and filtration first time, filtration has reduced particulate matter wherein, dust impurity and has removed part tar, can effectively reduce oxynitride, combustion gas after a dust removal by filtration enters again cuts stream direct current tornado dust collector and carries out final dusting, thoroughly pollutent such as dusting out.Gas after the dedusting carries out catalyzed reaction to the catalyzer storehouse again, generates the inflammable gas of high burning-value.

The water vapour that produces in the crackingsteam tank 14 feeds in thevapour pipe 17 ofvaporizer 10, inlet pipe by littleback pressure engine 12 1 sides after boosting enters in little back pressure engine, water vapour promotes to be installed inrotor 20 runnings on theaxis 21, just water vapour is changed into the interior energy of material by the mode of conducting heat,rotor 20 does work mutually withstator 19 and again heat energy is transformed into mechanical energy, and drive the work of whole little back pressure engine, drive the oxygen enrichment blower fan by theshaft coupling 22 that is installed on the axis again, the oxygen enrichment blower fan utilizes the infiltration rate difference when each component sees through oxygenpermeable membrane 23 in the air, under pressure difference drives, thereby make airborne oxygen preferentially obtain oxygen level greater than 20.93% gas by oxygenpermeable membrane 23, be oxygen enrichment, be blown into body of heater through the whirlwind road and make it continue reaction; Oxygen permeable membrane can be bought in market.The present invention adopts low temperature pyrolyzer, utilizes the waste heat in the burner hearth to meet the demands, and therefore the oxynitride that generates is very low, and environment is not almost polluted.High burning-value inflammable gas after catalyzed reaction enters the filtration and the cooling process of carrying out in the cracking steam tank again, and the combustion gas after the processing is delivered to user pipe by the combustion gas delivery port.

The integrated equipment of device provided by the invention, waste material such as the resistates of producing with grass, wood, bavin standing grain, stalk, agroforestry or brown coal, mud coal etc. are fuel, under 370 ℃-800 ℃, the organic matter in the fuel, charcoal and tar and main component have: O₂, H₂O, CO₂Deng vaporized chemical, main component have: CaCO₃, MnO₂, Ni, SO₂, SiO2, H₂Chemical reaction took place through 0.5～3 second and generates the inflammable gas that contains 40% methane, 11%～17% hydrogen, 10% carbon monoxide etc. greater than 20.93% oxygen rich gas in the catalyzer of O etc. and oxygen level.Decompose tar by cracking, waste oil is utilized effectively; Twice dedusting of bell jar and whirlwind makes combustion gas purer, and the inflammable gas of high burning-value takes place to become the more inflammable gas of high burning-value after the catalyzed reaction through the catalyzer storehouse, exceeds several times than the combustion value of traditional combustion, and for example, the fuel value of common fire coal is at 5000KJ/m³About, the fuel value of the high burning-value inflammable gas after pyrolysis gasification reaches 12000-20000KJ/m³More than.
