[0040] An air extraction component 8 is arranged on the purification cylinder 2, and one end of the air extraction component 8 is connected to the purification cylinder 2;

[0041] A purification component 9 is arranged inside the air extraction component 8.

[0042] For a purification device for biomass gas production provided by the present utility model, during use, the air extraction component 8 is started, so that the air extraction component 8 can extract the air on the inner wall of the purification cylinder 2, and then the gas on the inner wall of the biomass gasifier body 1 can quickly enter the connecting cylinder 4 from the connecting pipe 3.
