Embodiment Construction
[0037] The specific embodiments of the present invention will be further described below with reference to the drawings and technical solutions.
[0038] At the beginning of the work of the whole set of equipment, high-temperature air is introduced into the grate furnace combustion device 7, and the organic matter to be processed is put into the rotary kiln pyrolysis unit 5. The high-temperature air moves in the grate furnace combustion device 7 for combustion reaction. , The reaction produces high-temperature flue gas and ash. The high-temperature flue gas flows along the extended heating surface 42. During the flow, the high-temperature flue gas indirectly heats the organic materials in the rotary kiln pyrolysis device 5, and the rotary kiln pyrolysis device itself Continuous rotation ensures uniform heating, organic matter undergoes pyrolysis reaction, and pyrolysis volatile products and pyrolysis slag are produced. The heavy tar in the pyrolysis volatile product is condensed i...

The invention provides an outer heating pyrolysis and combustion integrated device and method, and belongs to the technical field of energy environment protection. The device comprises a raw material bin, a feeding device, a rotary kiln pyrolysis device, a grate furnace combustion device, a pyrolysis slag bin, an air preheater, a pyrolysis volatilization product recycling device and a smoke purifying device. Organic matter in the raw material bin is sent into the rotary kiln pyrolysis device through the feeding device, the organic matter in the rotary kiln pyrolysis device is subjected to the pyrolysis reaction, pyrolysis gas, pyrolysis oil and pyrolysis slag are generated, and high-quality pyrolysis gas and pyrolysis oil are sent into the pyrolysis volatilization product recycling device to be recycled; and the pyrolysis slag is sent into the grate furnace combustion device through the pyrolysis slag bin for combustion, high-temperature smoke generated in the combustion process indirectly heats the organic matter in the rotary kiln pyrolysis device in an outer heating form, the organic matter in the rotary kiln pyrolysis device is subjected to the pyrolysis reaction again, low-temperature smoke obtained after heat exchange is sent into the smoke purifying device, and the process is repeatedly conducted.
Description
Technical field [0001] The invention belongs to the technical field of energy and environmental protection, and relates to an external heat type pyrolysis and combustion integrated device and method, in particular to realize near-zero emission of organic matter for organic matter pyrolysis and combustion treatment, and recover the resources contained therein. Background technique [0002] With the development of industrial production and the improvement of human material life, a large amount of organic waste is produced, and the amount of production is increasing. The harmless treatment of organic waste is difficult and costly, and ordinary treatment methods will cause environmental pollution. Moreover, organic waste has great value in recycling, especially when energy is facing exhaustion worldwide, the significance is more profound. Summary of the invention [0003] The present invention provides an external heat type pyrolysis and combustion integrated device and method. The py...
