Abstract

The invention provides an air distributing and ash discharging device of an upward suction type gasifier. The air distributing and ash discharging device comprises enamel and a gasification bucket. A body of the gasification bucket is in the shape of a funnel with the upper portion larger than the lower portion, the inclination angle of the funnel is alpha, and alpha is smaller than or equal to 60 degrees. The enamel is arranged at the top of the body, and gasifier legs are arranged below the enamel. A slag smashing pipe is arranged in the middle of the gasification bucket, an electronic ignition pipe is arranged on the lower portion of the gasification bucket, an ash storage box body is arranged at the bottom of the gasification bucket, and an inner barrel communicated with the gasification bucket is arranged on the upper portion of an inner cavity of the ash storage box body. An air distributing plate is arranged at the top of the inner barrel, a plurality of small holes are evenly distributed in the center of the air distributing plate, the diameter of the small holes is zeta, and phi 3<=zeta<=phi 12. The sum of the areas of the small holes is equal to or smaller than the cross sectional area of an air inlet pipe. An ash control plate is arranged at the bottom of the inner barrel, the ash control plate and the air distributing plate are used in cooperation, the discharging amount of ash is controlled, the parallel distance between the ash control plate and the air distributing plate is xi, and 90 mm<=xi<=240 mm.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a gas distribution and ash discharge device for an updraft gasifier. Background technique [0002] The research on biomass gasification technology continues to deepen, and its application prospects in the fields of environmental protection and new energy are very broad. [0003] Biomass gasification is the conversion of hydrocarbons that make up biomass into CO, H 2 、CH 4 Process such as combustible gas. In order to provide the thermodynamic conditions for the reaction, the gasification process needs to supply air or oxygen to partially burn the raw materials. The difference between the gasification process and the common combustion process is that sufficient oxygen is supplied during the combustion process to fully burn the raw materials, the purpose is to directly obtain heat, and the product after combustion is CO 2 and water vapor and other non-recombustible flu...
