Abstract

The invention provides a gasification device for producing synthesis gas from a high-moisture organic material, and belongs to the field of gasification devices. The gasification device for producingsynthesis gas from a high-moisture organic material comprises: a feeding device, 1-3 pyrolysis reactors, a gasification reactor, a solid particle separator, a residual coke box, a gas purification device and a combustion device. The pyrolysis reactor is vertically arranged and the gasification reactor is horizontally arranged, so that the pyrolysis reactor and the gasification reactor are arrangedin an L shape. According to the invention, the problem of unstable system operation caused by aging and failure of the catalyst is avoided; meanwhile, latent heat and volatile matter of water vapor and sensible heat and chemical heat of pyrolytic carbon are fully utilized, so that energy consumption is reduced, economical efficiency is improved, cheap activating agents such as dolomite can be conveniently added into materials with high moisture content to serve as catalysts under the necessary condition, and an expensive reactor for containing the catalysts does not need to be specially arranged.

Description

technical field [0001] The invention relates to a gasification device, in particular to a gasification device for generating syngas from high-moisture organic materials, and belongs to the field of gasification devices. Background technique [0002] Due to low economic benefits and strict environmental protection regulations, the current disposal methods for garbage, sludge, and agricultural waste (such as straw, rice husk, etc.) are generally such as landfill, composting, and incineration, but these traditional methods are not Clean energy conversion from waste has not been realized. [0003] Currently, pyrolysis and gasification are considered as waste clean energy technologies. These technologies can reduce the volume of flue gas and fix heavy metals in solid residues, while producing valuable oil and syngas products, which have great advantages in terms of reduction, harmlessness and resource utilization. Ordinary gasification technology and devices use air as the gasi...
