Abstract
The invention discloses a deslagging method and a deslagging device for a biomass gasifier. The invention is characterized in that a deslagging device is arranged at the bottom of a hearth (1); the deslagging device consists of an annular sieve plate (14) and an annular air duct (18); under the vibration of the annular sieve plate (14), slag enters the annular air duct (18) through the annular sieve plate (14); a deslagging air inlet (8) is connected in one tangent direction of the annular air duct (18) and is used for blowing air into the annular air duct (18); a deslagging opening (4) is connected in another tangent direction of the annular air duct (18) and is used for deslagging outwards; after the slag enters the annular air duct (18), air is blown into the deslagging air inlet (8) and the slag is discharged from the deslagging opening (4) under the action of a blowing force. Through vibration of a vibrating sieve, small ash and the slag enter the annular air duct through big sieve pores and small sieve pores and are easily discharged from the deslagging opening, thus a complicated deslagging mechanical device is eliminated.
