Abstract

The invention discloses a high-efficiency and low-pollution rural garbage pyrolysis method and a device thereof. It includes an outer cylinder, a middle cylinder and an inner cylinder, which are set sequentially from outside to inside; the inner cylinder is used as the first flue gas channel, and the cavity formed between the inner cylinder and the middle cylinder is used as a garbage pyrolysis chamber. The cavity formed between them is used as the second flue gas channel; the outer peripheral wall of the inner cylinder is equipped with spiral blades for pushing garbage; The helical guide track of the guide vane flows. The high-temperature flue gas flows through two flue gas channels to transfer heat to the garbage pyrolysis chamber and heat the garbage in it; the garbage is pyrolyzed while moving forward in the garbage pyrolysis chamber under the push of the spiral blade. The waste pyrolysis product in the pyrolysis process of the present invention can be burned and reused. On the one hand, it is used to generate high-temperature flue gas to provide heat to the waste drying device and waste pyrolysis device, and on the other hand, it is used for residential life and industrial and agricultural production.

Description

technical field [0001] The invention relates to garbage treatment, in particular to a high-efficiency and low-pollution rural garbage pyrolysis method and device thereof. Background technique [0002] Disposal of domestic and production waste of rural residents has always been a difficult problem, and the direct incineration treatment method will even aggravate the smog situation in the north. Municipal solid waste treatment technologies mainly include landfill, composting, and heat treatment technologies. The treatment of rural garbage is still in the backward stage of scattered disposal or incineration. Some garbage is discarded on the roadside and directly exposed to the air, resulting in a messy environment; some garbage is incinerated, billowing black smoke and polluting the atmosphere. [0003] At present, the commonly used waste heat treatment technologies include direct incineration and pyrolysis gasification. Direct incineration is a solid-state heterogeneous comb...
