Combined solid waste gasifier

Abstract

The invention provides a combined solid waste gasifier with a plurality of single furnaces, which can meet the requirement of solid waste treatment on a larger scale. The combined solid waste gasifier is provided with a gasifier body and gasifier legs for supporting the gasifier body. The top of the gasifier body is provided with a waste feed inlet and a pyrolysis gas outlet. The bottom of the gasifier body is provided with a grate and a bottom gas inlet pipe. The gasifier body is composed of at least two single furnaces, and the single furnaces are provided with shared walls, shared wall gas inlet pipes and shared wall gas inlet holes. The combined solid waste gasifier has the advantages that the gasifier body is composed of the single furnaces, and accordingly, independent waste gasification in each small furnace cavity is guaranteed, investment is saved, and waste treatment amount is enlarged; and the small furnace cavities share the walls, the area of heat emitted out from the walls is half reduced at least, and accordingly compared with a simply combined single gasifier, the combined solid waste gasifier is lower in heat loss and higher in gas yield.

Description

technical field [0001] The invention relates to a garbage treatment device, in particular to a garbage pyrolysis gasification device. Background technique [0002] With the continuous progress of the society, the continuous improvement of the level of civilization, and the continuous strengthening of people's awareness of environmental protection, the requirements for urban sanitation equipment are also getting higher and higher. Garbage is an object of urban cleanup. Whether it is properly disposed of is not only directly related to people's living environment, but also has a potential impact on natural ecosystems. At present, a large amount of urban waste is disposed of through large-scale landfills. The landfilled waste can be decomposed naturally, but the land consumption is large, and it is easy to cause groundwater pollution; the modern new and more environmentally friendly method is to use high-temperature incineration or pyrolysis gas It is not only cleaner, but als...

AI Technical Summary

Problems solved by technology

In this way, every additional gasifier needs to add a set of auxiliary facilities, such as pipelines, feeding mechanisms and fire grates, etc., which requires a large investment in equipment, complicated management, and a single furnace with large heat loss and low efficiency.
