<p>The present utility model discloses a hot-air heating type biomass pyrolysis machine comprising a pyrolysis cabin. The pyrolysis cabin mainly comprises a housing and a charging barrel disposed in the housing. A gap is reserved between the periphery of the wall of the charging barrel and the housing. A hot-air inlet pipe that is close to one end of the charging barrel and is in communication with the gap is disposed on the housing. A hot-air outlet pipe that is close to the other end of the charging barrel and is in communication with the gap is disposed on the housing. The hot-air outlet pipe is provided with an exhaust fan. A spiral hot-air channel is disposed in the gap along the axis direction of the charging barrel, and two ends of the spiral hot-air channel are in communication with the hot-air inlet pipe and the hot-air outlet pipe separately, so that the stay time of hot air in the housing is extended, so as to achieve the objective of sufficiently exchanging heat. Because the hot-air heating structure form is used, the energy consumption is reduced, so that the hot-air heating type biomass pyrolysis machine has the characteristics of energy saving and environment friendliness; in addition, biomasses are more uniformly heated, so that the hot-air heating type biomass pyrolysis machine also has the characteristic of good pyrolysis effect.</p> |
