Wet-type deslagging device of biomass gasifier

Abstract

The invention relates to the technical field of biomass energy, and discloses a wet-type slag discharging device of a biomass gasifier, the wet-type slag discharging device comprises a furnace body, the interior of the furnace body is divided into five areas from top to bottom, and the five areas specifically are a drying area, a cracking area, an oxidation area, a reduction area and an ash discharging hopper; one side of the furnace body positioned in the oxidation area is fixedly sleeved with an air inlet piece, the other side of the furnace body positioned in the reduction area is fixedly sleeved with an air outlet piece, the outer wall of the furnace body positioned below the ash discharge hopper is fixedly sleeved with a water tank, and the water tank is filled with liquid water. The fixing columns are arranged in the water tank, the blocking plate and components of the blocking plate can move up and down in the water tank through the side grooves in the outer sides of the fixing columns, ash falls into the top end of the blocking plate before falling into water through blocking of the blocking plate, heat of the ash is transmitted into the water storage part through the conduction part, the initial temperature of the ash is effectively reduced, and the ash can be prevented from falling into the water storage part. And the water impact phenomenon is reduced.

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to a wet slagging device of a biomass gasifier. Background technique [0002] Biomass gasifier is a new type of gas production equipment. It uses biomass particles as raw materials, and performs a series of gasification operations on the raw materials under high temperature conditions to convert them into combustible gases. The gasification process is divided into biomass raw materials. The four processes of oxidation reaction, reduction reaction, cracking reaction and drying, the combustible gas produced by it is green energy, which is conducive to maintaining the balance of atmospheric carbon dioxide and reducing the greenhouse effect. [0003] After the existing biomass gasification furnace is gasified, ash will be generated at the bottom of the furnace, and the device for cleaning the ash and slag often adopts a wet slagging device with a water seal structure, which can e...
