The biomass enters the pyrolysis chamber from the feeding opening and is discharged from the discharging opening after being cracked in the pyrolysis chamber. The whole process is continuous. The pyrolysis time of the biomass is controlled by adjusting the rotating speed of the pyrolysis chamber hinge. The sealing of the pyrolysis chamber is realized by the feeding hinge, the pyrolysis chamber hinge and the discharging hinge. The gas matter generated during pyrolysis orderly enters the first condensation tower and the second condensation tower through the gas conveying pipeline above the pyrolysis chamber. The tar and the wood vinegar are obtained by separating. The rest gas enters the gas cleaning system. A part of the combustible gas discharged from the gas cleaning system enters the burner for recycling, and the rest combustible gas is output through the combustible gas outlet for other use.
