Title:
BIOMASS CONVERSION SYSTEM AND METHOD BASED ON GASIFICATION
Document Type and Number:
WIPO Patent Application WO/2021/185223
Kind Code:
A1
Abstract:
The present invention provides a biomass conversion system based on gasification, comprising: a baking furnace, a gas-solid separation device, a gasification furnace, and a combustion furnace, wherein the baking furnace is communicated with external waste heat flue gas and the gas-solid separation device, the gas-solid separation device is further communicated with the combustion furnace and the gasification furnace, and the combustion furnace is further communicated with the outside. The present invention further provides a biomass conversion method based on gasification, comprising the steps that: the baking furnace bakes a biomass raw material by using waste heat flue gas; gas and a solid generated by baking are separated by the gas-solid separation device; a gas product obtained by separation is conveyed to the combustion furnace, and the obtained solid is conveyed to the gasification furnace; and the gasification furnace gasifies and decomposes the solid under the action of high-temperature flue gas, a generated volatile component is conveyed to the combustion furnace, and generated gasified coke serves as a final product. The biomass conversion system and method based on gasification of the present invention have the characteristics such as low energy consumption, low costs, high cleanliness, better product quality, and can be widely applied to the field of biomass conversion.
