Agroforestrial biomass gasification furnace adapted to multiple raw materials

Abstract

The invention discloses an agroforestrial biomass gasifying furnace adapted to multiple raw materials, which comprises a rotary poking device, a hydraulic poking elevator and a feeding inlet which are arranged on the top part of a gasifying furnace, wherein a gasifying reaction chamber is arranged in the cavity of the gasifying furnace; the gasifying reaction chamber is divided downwards into a preheating dry chamber, an oxidizing reaction chamber, and a reducing reaction; the middle-lower part of a furnace body is provided with an automatically-overturned grate which is transmitted on the exterior of the furnace body; and the bottom part of the furnace body is provided with a continuously rotary carbon discharging device. The gasifying furnace disclosed by The invention has advantages that hub-shaped material is reacted in the gasifying furnace so as to discharge the carbon continuously; the grate is rotated so that all casting-iron finned tubes are arranged horizontally; rice-hull-shaped light-small material is reacted in the gasifying furnace; casting-iron tubes are rotated timely so as to discharge material discontinuously; the bottom of the gasifying furnace is provided with a conically rotary device with a pocking sheet and a pocking nail; in a rotating procedure, the poking sheet is rotated so that the gasifying furnace discharges the material evenly; the poking nail prevents the gasifying furnace from being bridged in a cone shape; the gasifying furnace realizes a purpose that multiple raw materials use a same type of furnaces; the furnace body can be enlarged through measure disclosed by The invention; gas production quantity of the single furnace is increased; and the agroforestrial biomass gasifying furnace is adapted to multiple raw materials and realizes industrialization and scale production.

Description

technical field [0001] The invention relates to an agricultural and forestry biomass gasifier adapted to various raw materials, belonging to the field of agricultural and forestry biomass energy. Background technique [0002] For example, the existing invention titled "Agricultural and Forestry Biomass Secondary Process Reaction Gasifier and Its Application" patent application number 201110259407.2 is only applicable to wood chip biomass. For biomass like rice husks in the gasification process The gas outlet is sucked out in large quantities; the following problems exist in the operation process of the current fixed-bed gasifier: 1. The types of the currently used agricultural and forestry biomass gasifiers are all different types of gas designed for different characteristics of raw materials. In the production process, the raw materials of agricultural and forestry organisms cannot be strictly distinguished, and can only be roughly screened according to their size; second, ...
