Problems solved by technology

[0007] The pyrolysis method varies greatly depending on the pyrolysis reactor (pyrolysis furnace) technology. The "batch" pyrolysis furnace can feed materials once and discharge slag once, so it cannot be continuously produced, and the processing scale of the pyrolysis furnace is small; " The continuous type pyrolysis furnace has a small processing scale, and the continuous operability is not high due to various factors. At present, both "intermittent" and "continuous" pyrolysis furnaces use organic solid waste in the furnace, heat carrier (External heat supply) Outside the furnace, the "indirect" heat supply and pyrolysis method in which the organic solid waste in the jacket is in direct contact with the heat has low heat transfer efficiency and low heat absorption efficiency, resulting in low heat utilization efficiency and heat loss. Problems such as slow decomposition reaction speed, long reaction time, high energy consumption, pyrolysis solid residues cannot meet the requirements of ultra-clean emission environmental protection indicators, etc.
