Embodiment
The technique means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
During concrete enforcement, composition graphs 1, wherein solid arrow direction indication is air-flow direction, and dotted arrow direction indication is the flow direction that vapourizing furnace produces gas.A kind of stalk gasifier, comprises body of heater 1 and gas tank 2.Body of heater 1 is connected with gas tank 2 by tracheae 5.Gas tank 2 is designed to innermost layer hot gas path 7, center air passage 9, outermost layer hot gas path 10.Be provided with strainer 8 in innermost layer hot gas path 7, strainer 8 filters the tar in the gas after burning and impurity.Gas in innermost layer hot gas path 7 enters outermost layer hot gas path 10 after passing through strainer 8, and the gas in outermost layer hot gas path 10, through tracheae 13, pond 14, is discharged from escape pipe 15.Pond 14 is to cooling further through air cooled gas and removing impurity.Center air passage 9 is connected with gas blower 3 by inlet pipe 19, and center air passage 9 is connected with body of heater 1 by tracheae 11.Body of heater and gas tank can be cylindrical.
During specific works, stalk is put into body of heater, light stalk, utilize sealing cover by gasification furnace sealing.Gas after body of heater combustion enters the innermost layer hot gas path of gas tank by tracheae, and the gas in innermost layer hot gas path, from top to bottom after the tar in metre filter gas and impurity, enters the outermost layer hot gas path of gas tank.Open gas blower, gas blower blasts air by inlet pipe in the center air passage of gas tank, gas in air in middle layer and innermost layer hot gas path, outermost layer hot gas path carries out heat exchange, make the gas cooling in outermost layer hot gas path, cooled gas enters pond by tracheae and cools further, discharges from escape pipe.Air in air passageways after heat exchange enters body of heater by tracheae, in body of heater, straw burning provides oxygen, makes the stalk Thorough combustion in body of heater.
