A self-powered pyrolysis combustion time-sharing reaction device and method for organic matter

Abstract

A self-powered pyrolysis combustion time-sharing reaction device and method for organic matter, the device includes a pyrolysis combustion time-sharing reaction device, a feeding device, a pyrolysis volatile product recovery device and a flue gas purification device. The whole process is mainly composed of two time-sharing reaction stages of pyrolysis and combustion: the organic matter is sent into the pyrolysis and combustion time-sharing reaction device, and the thermosolid carrier heats it rapidly to cause a pyrolysis reaction, and the pyrolysis volatile products produced enter the thermal The pyrolysis volatile product recovery device is used to recover pyrolysis gas and pyrolysis oil; after the pyrolysis reaction is completed, air is introduced into the pyrolysis combustion time-sharing reaction device for combustion with the remaining pyrolysis volatile products and pyrolysis slag. The generated heat heats the thermosetting carrier, the flue gas is purified and discharged, and the heated thermosetting carrier stays in the pyrolysis combustion time-sharing reaction device to provide energy for the next pyrolysis of organic matter, and so on. The device has the advantages of energy cascade utilization, short pyrolysis reaction time, high heat transfer efficiency and the like.

Description

technical field [0001] The invention relates to a time-sharing reaction device and method for self-powered pyrolysis and combustion of organic matter, which belongs to the field of organic matter resource utilization and environmental technology, especially for the time-sharing treatment of organic matter pyrolysis and combustion to realize near-zero emission of organic matter and recover the resources contained therein . Background technique [0002] Low-rank coal accounts for a large proportion of the world's coal resources, but due to the relatively high gelling components in the low-rank coal components, the high volatile content in the industrial analysis composition, and the many side chains in its organic matter structure, direct combustion Or the gasification efficiency is low; on the other hand, the chemical reactivity is too high, and it is easily weathered and broken in the air, which is not suitable for long-distance transportation and long-term storage.

[0002] Low-rank coal accounts for a large proportion of the world's coal resources, but due to the relatively high gelling components in the low-rank coal components, the high volatile content in the industrial analysis composition, and the many side chains in its organic matter structure, direct combustion Or the gasification efficiency is low; on the other hand, the chemical reactivity is too high, and it is easily weathered and broken in the air, which is not suitable for long-distance transportation and long-term storage. Therefore, in-situ treatment, upgrading and modification are the key to the utilization of low-rank coal link

[0003] With the development of industrial production and the improvement of human material life, a large amount of organic waste has been produced, including waste tires, household garbage, oily sludge and other organic waste, and the amount of organic waste is increasing day by day. Organic waste should be treated in a harmless manner. Difficult and costly, common treatment methods will cause environmental pollution
