Biomass gasifier with V-shaped ash discharge port

Abstract

The invention relates to the technical field of biomass gasification furnaces, and discloses a biomass gasifier with a V-shaped ash discharge port. The biomass gasifier comprises a furnace body, the interior of the furnace body is divided into a drying zone, a cracking zone, a reduction zone, an oxidation zone and an ash discharge zone from top to bottom, the side wall of the furnace body located at the junction of the oxidation zone and the ash discharge zone is fixedly sleeved with a fixing plate, a hole is formed in the middle of the fixing plate, and the fixing plate is movably connected with a transmission assembly in a sleeving mode through the hole. The fixing plate and a rotating blade are arranged between the V-shaped ash discharge area and the oxidation area, and the rotating blade rotates and is matched with the fixing plate for use, so that the falling direction of slag is uniform and symmetrical effectively, the one-time falling amount of the slag is 1 / 2 of the original falling amount, and the blockage of an ash discharge port caused by excessive one-time falling of the slag is prevented; and meanwhile, the rotation of the rotating blade pushes the slag at the bottom layer of the oxidation area to fall down, so that the original slag discharging mode of automatic falling is changed, the pushing force for guiding out the slag is increased, and the guiding-out rate of the slag is improved.

Description

technical field [0001] The invention relates to the technical field of biomass gasification furnaces, in particular to a biomass gasification furnace with a V-shaped ash outlet. Background technique [0002] Gasification technology is a technology of thermochemical conversion of biomass, that is, under the condition of incomplete combustion of biomass fuel, the organic hydrocarbon chains with higher molecular weight are cracked and turned into flammable gases with lower molecular weight. The equipment of chemical technology is called biomass gasifier, which is equipped with drying area, cracking area, reduction area, oxidation area and V-shaped ash discharge area from top to bottom. The materials in the oxidation area and the air blown in Mixed combustion, the gas produced in this process reacts upwards through the reduction zone, cracking zone, and drying zone, and finally generates flammable gas. It has the advantages of wide application, low pollution, cleanliness and hig...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing biomass gasification furnace proposed in the background technology, the present invention provides a biomass gasification furnace with a V-shaped ash discharge port, which can improve the export rate of slag and prevent the discharge of ash. The clogging of the ash port prevents the accumulation of materials, increases the contact area between materials and air, and improves the gasification rate, which solves the technical problems raised in the above-mentioned background technology
