The invention relates to a multipoint-type catalytic
biomass gasification
machine which includes a fuel bin, a material adding opening arranged on a side surface of the fuel bin, a
mixed gas bin arranged under the fuel bin and an automatically residue-discharging
machine arranged between the fuel bin and the
mixed gas bin. The multipoint-type catalytic
biomass gasification
machine is characterized in that a material-pressing
system is disposed on the top of the fuel bin. An
internal temperature-decreasing gas bin is disposed in the middle of the fuel bin and two external temperature-decreasing gas bins are respectively arranged on the two sides of the fuel bin. A trapezoid
combustion chamber is disposed on the middle of the bottom of the fuel bin. Eight column-type
oxygen homogenizing and distributing disks are arranged around the
combustion chamber. An ignition hole is disposed above a gas inlet
pipe. A gas outlet is disposed on a side surface above the
mixed gas bin. A
pyroligneous acid discharging outlet is disposed under the gas outlet. A
sewage discharging hole and a
tar discharging hole are arranged on the top of the mixed gas bin. By means of the eight column-type
oxygen homogenizing and distributing disks,
oxygen is fed into the fuel bin uniformly. By means of multipoint-type
catalysis, a gas output speed is increased and a gas production amount is increased so that a
biomass fuel is saved. The invention can satisfy a production requirement of a large-scale gasification machine. By means of quick temperature decrease,
sedimentation speed of
tar and dust can be increased so that
fuel gas is more pure.
