step two: heating a gasification reaction furnace (4), drying biomass fuel dropped on a drying layer supporting plate (7), reducing moisture in the biomass fuel, dropping the dried biomass fuel on a cracking layer supporting plate (8) under the action of gravity for combustion cracking, dropping the biomass fuel on a reduction layer supporting plate (9) for combustion reduction after cracking, dropping the biomass fuel on an oxide layer supporting plate (10) for continuous combustion after reduction, discharging the waste residue after combustion through a slag outlet, discharging the generated gas through a gas outlet, starting a rotating motor (15) during combustion, rotating an output shaft of the rotating motor (15) to drive a driving wheel (20) to rotate, driving a rotating shaft (16) to rotate through power transmission, so that a cam (17) fixedly connected with the rotating shaft (16) rotates, the connecting rod (18) moves along with the cam, and a roller arranged at the top end of the connecting rod (18) periodically contacts with one side of a cambered surface of a second connecting block (13), so that the dry layer supporting plate (7), the cracking layer supporting plate (8), the reduction layer supporting plate (9) and the oxidation layer supporting plate (10) vibrate under the action of the compression spring (12), and the materials on the supporting plates are transferred under the action of gravity;
step three: the gas that produces gets into the dust removal liquid in the first cavity among the gas purification device (5) through first connecting pipe in, gets rid of the dust through the dust removal liquid, and in the gas arrived the second cavity, carbon dioxide and hydrogen sulfide gas body in the gas were absorbed, further gets rid of the hydrogen sulfide gas body in the gas through iron oxide filter screen (22), gets rid of the moisture in the gas through dry lime filter layer (23) at last, utilizes in flowing into boiler (6) through the second connecting pipe.
