Embodiment Construction
[0043] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.
[0044] A method for continuous pyrolysis combustion of organic matter, comprising the following steps:
[0045] Ⅰ Preheating stage: before the device starts to work, high-temperature air is used to preheat the thermosolid carrier 21 in the rotary pyrolysis device 5 until the temperature is 800°C;
[0046] Ⅱ Feeding stage: the low-viscosity organic matter in the low-viscosity organic matter raw material bin 2 is sent to the rotary pyrolysis device 5 through the screw feeding device 4; the high-viscosity organic matter in the high-viscosity organic matter raw material bin 1 is heated and melted by the pusher The feeding device 3 is sent into the rotary pyrolysis device 5 in a jet form to prevent the accumulation of high-viscosity organic matter;
[0047] Stage III of pyrolysis: Under the condition that the r...

The invention discloses a continuous organic matter pyrolysis and combustion integrated device and method, and belongs to the technical field of environmental protection on energy sources. The continuous organic matter pyrolysis and combustion integrated device comprises a raw material bin, a feeding device, a rotary pyrolysis device, a grate combustion device, a bell-type transmitting device, a blanking device, an air preheater, a pyrolysis devolatilization product recovery device and a flue gas cleaning device. The method comprises the following steps that organic matter and thermosetting carriers are mixed fully and evenly under rotation of the rotary pyrolysis device, quick pyrolytic reaction is conducted, pyrolysis gas, pyrolysis oil and pyrolysis residue are produced, the pyrolysis gas and the pyrolysis oil are sent into the pyrolysis devolatilization product recovery device for recovery, the pyrolysis residue passes through the blanking device and is sent into the grate combustion device, high temperature slag produced by combustion of the pyrolysis residue in the grate combustion device is used as supplementary heat source, passes through the bell-type transmitting device and is sent into the rotary pyrolysis device, the original thermosetting carriers in the rotary pyrolysis device are heated, and the high temperature thermosetting carriers after heat exchanging are used for pyrolysis of next batch organic matter. The continuous organic matter pyrolysis and combustion integrated device has the advantageous that the application range of organic matter is wide, and cascaded utilization of energy is achieved.
Description
technical field [0001] The invention belongs to the technical field of energy and environmental protection, and relates to a continuous pyrolysis and combustion device and method for organic matter, in particular to realizing near-zero emission of organic matter and recovering the resources contained therein for the pyrolysis and combustion treatment of organic matter. Background technique [0002] With the development of industrial production and the improvement of human material life, a large amount of organic waste has been produced, including domestic garbage, dewatered sludge, oily sludge and other organic waste, and the production volume is increasing day by day. Organic waste should be treated in a harmless manner. It is difficult and costly, and ordinary treatment methods will cause environmental pollution. Moreover, organic waste has great value in recycling, especially in the context of energy depletion worldwide. Contents of the invention [0003] The present i...
