A biomass gasifier with a V-shaped ash outlet

Abstract

The invention relates to the technical field of biomass gasification furnaces, and discloses a biomass gasification furnace with a V-shaped ash discharge port, which includes a furnace body, and the interior of the furnace body is divided into a drying area from top to bottom, Cracking area, reduction area, oxidation area, ash discharge area, the side wall of the furnace body located at the junction of the oxidation area and the ash discharge area is fixedly sleeved with a fixed plate, the middle part of the fixed plate is provided with a hole, and the fixed plate passes through the hole Actively socketed with the transmission assembly. The invention arranges a fixed plate and a rotating blade between the V-shaped ash discharge area and the oxidation area, and the rotating blade rotates and cooperates with the fixed plate to effectively make the falling direction of the slag uniform and symmetrical, and the falling amount of the slag at one time is The original one-half prevents the slag from falling too much at one time and causes the ash discharge port to be blocked. At the same time, the rotation of the rotating blade pushes the slag at the bottom of the oxidation zone to fall down, which changes the original slag discharge method that automatically falls off. The driving force for slag export increases the export rate of slag.

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
