Abstract

The invention discloses a multi-section spiral moving bed pyrolysis gasification device which comprises a dry-section reactor, a pyrolysis-section reactor and a gasification-section reactor. The dry-section reactor is used for drying materials, the pyrolysis-section reactor is used for pyrolyzing the materials, the gasification-section reactor is used for gasifying the materials, the dry-section reactor, the pyrolysis-section reactor and the gasification-section reactor are provided with feeding ports and discharging ports, the discharging port of the dry-section reactor is connected with thefeeding port of the pyrolysis-section reactor, and the discharging port of the pyrolysis-section reactor is connected with the feeding port of the gasification-section reactor. The device has the advantages that the standing time of the materials is controlled by adjusting the rotating speed of a motor, and matching amount of gasifying agents and the materials is manually and accurately controlledby combining the sectioned air supply speed of an air-distribution plate, so that physical and chemical properties of target products can be controlled.

Description

technical field [0001] The invention relates to the field of thermochemical conversion of biomass solid waste, in particular to a multi-stage spiral moving bed pyrolysis gasification device. Background technique [0002] As one of the technical approaches of biomass thermochemical conversion, biomass pyrolysis gasification technology is a conversion method that is cleaner and more efficient than direct combustion. Under the condition of high temperature and oxygen deficiency, biomass is converted into combustible gas, liquid mixture and Solid carbon, the product is determined by different process conditions, and the product can be used for power generation and heat supply, synthetic fuel and chemicals, etc. [0003] The core equipment of this technology is a pyrolysis gasification reactor. At present, the mainstream equipment for engineering application is fixed bed and fluidized bed, each of which includes different forms. The fixed bed has the advantages of simple structu...
