Problems solved by technology
Since pyrolysis is an endothermic reaction, external heating needs to be provided during the start-up stage, so the pyrolysis and combustion treatment of domestic waste requires considerable fuel consumption, resulting in high operating costs;
[0005] Secondly, the problem of energy waste is prominent
Due to the small scale of disposal, the total investment in thermal power generation is large, and there is no advantage in economies of scale. Therefore, the energy of general waste heat treatment is mainly discarded, resulting in energy waste

The invention relates to the technical field of household garbage treatment, in particular to a heat accumulating type miniaturized household garbage heat treatment system. The heat accumulating typeminiaturized household garbage heat treatment system comprises a pyrolysis system, a combustion system, a heat accumulating system and a heat conduction system which are connected through pipelines, wherein the pyrolysis system is correspondingly connected with the combustion system and the heat accumulating system, and the heat conduction system is arranged between the pyrolysis system and the heat accumulating system; and a heat accumulating part is arranged in the heat accumulating system and is made of a heat accumulating material. According to the system, flue gas waste heat is recoveredand stored through the heat accumulating system, and heat is provided in the waste pyrolysis combustion furnace starting stage, so that on one hand, energy recycling is realized, and on the other hand, fuel required by operation is reduced, thereby improving the comprehensive energy utilization efficiency and reducing the operation cost; and great significance is achieved for popularization and application of the current small-scale household garbage disposal technology and equipment.
Description
technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a thermal storage type miniaturized domestic waste heat treatment system. Background technique [0002] Garbage pyrolysis and re-combustion refers to the process of breaking the macromolecules of organic components in garbage under anaerobic conditions to produce small molecular gases, tar and residues. Small molecular combustible gases are fully mixed with air in the secondary combustion chamber. Homogeneous reaction, thus replacing the heterogeneous reaction of direct incineration. Compared with direct incineration, it is more suitable for small-scale harmless treatment of combustible solid waste. [0003] However, the thermal treatment of small-scale domestic waste still faces some bottleneck problems: [0004] First, the running cost is high. Since pyrolysis is an endothermic reaction, external heating needs to be provided during the start-up stage, so the...
