Description

Technical Field

[0001] The utility model relates to the field of low-temperature pyrolysis of organic solid waste, and more specifically, to a self-heating low-temperature pyrolysis device for organic solid waste. Background Art

[0002] Low-temperature magnetized pyrolysis furnace is an energy-saving and environmentally friendly equipment for rapid reduction and harmless treatment of organic waste. Its working principle is: the equipment first generates magnetized wind, i.e. magnetized air, through an energy conversion device, and then uses high-energy magnetized air to dry, carbonize and pyrolyze the organic waste in the equipment. After magnetization, the material is first dried and pyrolyzed, and then the harmful gases generated by pyrolysis and gasification are reduced by reducing the amount of magnetized air entering. In addition, under the condition of lack of oxygen, the organic waste is first carbonized and releases a large amount of heat. Under the condition of high heat, the organic matter is continuously pyrolyzed and finally decomposed into small molecules such as carbon dioxide and water vapor and a small amount of residual ash. The low-temperature magnetized pyrolysis furnace uses magnetized air to make gasification and pyrolysis at a low temperature below 350°C, thereby basically eliminating the generation of dioxins. At the same time, it makes full use of the high heat generated by spontaneous combustion of the material, making the energy consumption of the equipment extremely low, and truly realizing the rapid reduction and harmless treatment of garbage.
