Embodiment

[0209] In a specific embodiment, according to the volume of the pyrolysis furnace, the amount of wood required for the low-temperature pyrolysis method of the present invention using wood as the first energy source and the verification of using corundum mullite as the heat storage material are further calculated. The pyrolysis can be carried out continuously in the absence of external energy.

[0210] Furnace shape and volume

[0211] The lower furnace body is a cylinder with an inner diameter of 1800mm and a net height of 1300mm. It is used as a pyrolysis reaction chamber for domestic waste organic matter, with an effective volume of 3.0m 3 ;The top of the furnace is a circular platform, which is used as a pyrolysis gas chamber after the reaction; the outlet is a flue with a diameter of 600mm, which is connected to the electric tar catcher and the corona plasma purification exhaust gas device through the flange.

Abstract

The invention relates to a domestic garbage low-temperature pyrolysis treatment method. Low-temperature pyrolysis is used, and heat which is stored in heat storage materials and generated in the garbage pyrolysis process is adopted and used for continuing to treat new garbage, so that the purpose of continuous garbage pyrolysis is achieved without the need for continuous adding of external energy. In addition, secondary pollutants generated by pyrolysis are treated by combining electrical tar precipitator technology and corona plasma air purification technology, and direct smokeless peculiar-smell-free discharge of domestic garbage pyrolysis is achieved.

Description

technical field [0001] The invention relates to the technical field of low-temperature pyrolysis treatment of domestic garbage, and more particularly, relates to a method for low-temperature pyrolysis of thermal storage type smokeless direct discharge domestic garbage. Background technique [0002] Garbage is solid waste generated in human daily life and production. Garbage disposal is to quickly remove garbage, and conduct harmless treatment, and finally make reasonable use of it. [0003] At present, the commonly used waste disposal methods in the world mainly include landfill, high-temperature composting, and incineration. The proportions of these three main waste disposal methods vary due to factors such as geographical environment, waste composition, and economic development level. [0004] Landfill will cause serious geological water and soil pollution. Because human domestic waste includes many toxic and harmful substances, germs, viruses and various heavy metal ele...
