Miniature movable type agricultural and forest biomass fast pyrolysis device

The invention discloses a miniature movable type agricultural and forest biomass fast pyrolysis device. The device comprises a traveling mechanism (25), a combustion furnace (18), a feeder (21), a fast pyrolysis reactor (22), a gas solid separator (23), a gas condenser (11), a non-condensable gas purifier (24), a fan (16), a gas buffer tank (17) and a gas preheater (19); the height of the fast pyrolysis reactor (22) can be adjusted, the device can be suitable for various agricultural and forest biomass raw materials, and the fluidization quality in the reactor is better due to the arrangementof an inverted-cone-shaped gas flow stabilizer in a top cover of the reactor; the non-condensable gas is taken as gas sources of spouting gas and fluidized gas and heat supply fuel, the entire deviceis simple in structure, small in volume and stable in running, can be hauled to the agricultural and forest biomass for production intensively and has lower production cost; the small-scale movable type operating mode also avo
