Device and method for clean incineration of solid waste organic matter

Abstract

The invention belongs to the technical field of energy conversion of solid materials containing organic matter, and relates to a device and method for clean incineration of solid waste organic matter. , flue gas purification and other components; through the thermal decomposition of solid waste organic matter in an oxygen-free atmosphere, it is converted into combustible gas and biochar, and then the combustible gas is aerobically cleanly burned to provide heat energy for the pyrolysis and drying of system materials to achieve solid waste The purpose of clean incineration of organic matter and energy self-sufficiency; the present invention prolongs the time and space between the two stages of pyrolysis and combustion in the pyrolysis combustion process, and realizes that only the volatile gas produced by the thermal decomposition of solid waste organic matter is burned in the combustion stage as itself or Heat is provided from the outside, and solid-phase materials are mainly thermally decomposed, rather than directly burned, thereby reducing secondary pollution and waste gas purification costs caused by direct solid incineration, and achieving the goal of clean incineration of solid waste and organic matter as resources.

Description

technical field [0001] The invention belongs to the technical field of energy conversion of solid waste containing organic matter, and in particular relates to a device and method for clean incineration of solid waste organic matter. Background technique [0002] The incineration of solid waste organic substances such as urban sludge and urban garbage is now a resource-based treatment method recognized by foreign countries. At the same time, the solid waste incineration process produces a large amount of flue gas and many harmful components, and the equipment investment and operating costs required for its purification are relatively large, which has become a bottleneck in the development of engineering applications. The resource utilization of solid waste organic matter is mainly the organic matter in it, and the organic matter can be easily converted into clean liquid or gas phase fuel under the condition of anaerobic low-temperature pyrolysis. This process can effectively...

Problems solved by technology

However, this combination mainly divides pyrolysis and combustion machinery into two processes in isolation, and separates pyrolysis and combustion machinery in isolation, resulting in a greatly reduced thermal efficiency of the system, increased operating costs, and the acidic viscous liquid phase produced in the system Tar is very easy to adhere to the inner wall of pipelines and equipment, causing pipeline blockage and equipment corrosion, affecting the normal operation of the system, and it is difficult to carry out engineering promotion and application
