[0004] CN104560072B introduces a pyrolysis system for organic waste, which uses a rotary bed pyrolysis furnace, and performs cooling and purification treatment on the pyrolysis gas to obtain pyrolysis gas, pyrolysis oil and pyrolysis slag, but the whole process is carried out manually operation, and the invention does not provide the principle of temperature selection for different waste pyrolysis media; CN1175429C introduces a kind of organic waste decomposition device and method, including two stages containing partial oxidation series reactors, and the partial oxidation heat medium part can be combined with organic waste Oxidation reaction occurs, self-compensating heat supply, but the device also lacks an intelligent control system, and cannot control the pyrolysis temperature according to different waste sources; CN105509062B introduces a full-scale continuous pyrolysis and incineration device for electronic and electrical waste. It can carry out integrated treatment of electronic and electrical waste, complete the integrated process of pyrolysis, premixing and combustion, and realize the green disposal of electronic and electrical waste
However, the device is highly targeted and does not have universal applicability to various organic solid wastes; in summary, there is no intelligent automatic pyrolysis device for various organic solid wastes on the market. Based on this, the present invention develops an intelligent Slagging solid waste thermal cracking treatment device

The invention belongs to the technical field related to solid waste treatment, and particularly discloses an intelligent thermal cracking treatment method and system for slag-state solid waste. The treatment method comprises the steps that S1, the solid waste to be treated is dried and crushed to obtain a to-be-thermally cracked material, the water content and the heat value in the to-be-thermallycracked material are monitored correspondingly, and thus the drying temperature and the thermal cracking reaction temperature are controlled; a thermal cracking reaction is conducted, and the mass ofobtained thermal cracking slag or thermal cracking oil is measured and recorded; and S2, the particle size of the thermal cracking material is changed, the step S1 is repeated for multiple times, therelation between the particle size of the to-be-thermally cracked material and the mass of the thermal cracking slag or the thermal cracking oil is established, the particle size is adjusted till themass of the thermal cracking slag or the thermal cracking oil obtained for multiple times under a certain particle size is within a preset acceptable floating range, thus the particle size of the to-be-thermally cracked material before thermal cracking is determined, and online intelligent control and adjustment are achieved. Through the intelligent thermal cracking treatment method and system for the slag-state solid waste, the purpose that one device contains multiple solid waste is achieved, robustness is good, and the guidance direction is provided for the solid waste treatment industry.
Description
technical field [0001] The invention belongs to the technical field related to solid waste treatment, and more specifically relates to an intelligent thermal cracking treatment method and system for slag-state solid waste. Background technique [0002] In recent years, with the continuous advancement of science and technology, the production and manufacturing capabilities of enterprises have been continuously improved, and the modernization process of our country has been accelerating, but it has also brought many environmental problems. Among them, solid waste has always been a hot research topic at home and abroad because of its various characteristics and complex composition. [0003] At present, the treatment methods for solid waste mainly include landfill treatment, incineration treatment, pyrolysis treatment, biocomposting and so on. Among them, pyrolysis treatment is favored by the scientific and industrial circles due to its obvious reduction, less pollutant dischar...
