Abstract

The invention relates to an urban garbage gasification and energy utilization system and method, specifically to a garbage material gasification and energy utilization system composed of a garbage gasification reaction device, a gasifying agent generation device, a fuel gas purification treatment device, a garbage crushing, drying and airtight feeding device, an airtight deslagging device, an oxidizing agent input device and the like, and an urban garbage gasification and energy utilization method. The system is characterized in that the gasifying agent generation device generates a hypoxic high-temperature gasifying agent which is required by garbage gasification and of which the temperature can be effectively controlled according to garbage materials and process requirements, garbage materials are directly contacted and acted with the hypoxic high-temperature gasifying agent to generate a gasification reaction, and the garbage gasification reaction device provides a space structure and reaction conditions of the gasification reaction. According to the gasification and energy utilization requirements, while the gasification reaction is maintained and the fuel gas is generated andoutput, the hypoxia high-temperature gasifying agent can be output as high-temperature heat energy, so that clean and efficient gasification and energy utilization are realized; and the system and themethod have the characteristics of high gasification and energy efficiency, no dioxin generation, suitability for urban garbage containing hydrocarbon components and the like.

Description

technical field [0001] The invention relates to a clean and efficient garbage gasification system and method, and a garbage energy clean utilization system and method, in particular to a garbage gasification system, an energy utilization system, a garbage gasification method and an energy utilization method. Background technique [0002] The large amount of garbage produced by cities of all sizes leads to increasingly serious environmental problems, and there are serious pollution discharge problems in the existing garbage disposal methods and processes. Due to the complex sources and components of various types of urban waste and the huge quantity, it has caused increasingly serious "garbage siege" phenomenon and environmental protection problems to cities and towns of various sizes. For a long time, the final disposal methods of urban waste are landfill and waste incineration: the former needs to occupy a large amount of land, and at the same time cause serious or even per...
