Biomass gasifying machine

Abstract

The invention discloses a biomass gasification machine and belongs to the technical field of a biomass gasification device. The biomass gasification machine comprises a furnace body with a furnace cover, wherein an inner chamber of the furnace body is divided into a furnace hearth and an ash chamber by an annular gasifying agent preheating chamber on the lower end of the furnace body; the lower end of the furnace body is provided with a gearbox; an output shaft of the gear box is a central shaft of the furnace body; the central shaft is connected with a furnace base plate through a dynamic sealing device; the upper end of the central shaft is fixedly connected with a bracket in the furnace hearth; an inner ring bracket of the gasifying agent preheating chamber is fixedly connected with a steam generator; the gasifying agent preheating chamber is communicated with a gas outlet pipe of the steam generator; the gasifying agent preheating chamber is communicated with a gasifying agent input pipe along the tangential direction; a plurality of jet nozzles are arranged on an inner ring of the gasifying agent preheating chamber; the central shaft is fixedly connected with an wind distribution furnace disc and a pressure stirring arm of an eccentric tower; and the upper end of the furnace body is provided with a fuel gas port. The biomass gasification machine has the advantages of long gas production time, stable and continuous operation, no flameout in midway, environmental protection, energy conservation, explosiveness prevention, and high thermal mass.

Description

technical field [0001] The invention relates to a gasification device, in particular to a crop straw or other biomass gasification device. Background technique [0002] The current so-called straw gasifiers or biomass gasifiers generally have some serious performance problems, such as: fire layer perforation, fire layer bridging and fire layer inclination will lead to qualitative changes in gasification products, resulting in non-combustible smoke, resulting in The gas production time is short, the continuity and stability are poor, the fuel cannot be fully burned, and the waste is large, making it unable to operate normally. Contents of the invention [0003] Based on the defects of the prior art, the purpose of the present invention is to: provide an automatic control fire layer change, long gas production time, fuel can be fully burned, stable and continuous work, not extinguishing halfway, and environmental protection, energy saving, explosion-proof and high heat High...

[0002] The current so-called straw gasifiers or biomass gasifiers generally have some serious performance problems, such as: fire layer perforation, fire layer bridging and fire layer inclination will lead to qualitative changes in gasification products, resulting in non-combustible smoke, resulting in The gas production time is short, the continuity and stability are poor, the fuel cannot be fully burned, and the waste is large, making it unable to operate normally. The product is only an experimental phenomenon of gas generation due to thermal solution, which has no practicality and promotion value.
