The invention relates to a spouting-cyclone overlapping multi-point material feeding recycling type decomposing furnace. The spouting-cyclone overlapping multi-point material feeding recycling type decomposing furnace comprises a decomposing furnace body (1), a gooseneck (2) and a material separation and circulation device (3) which are connected in sequence; the material separation and circulation device is further connected with the decomposing furnace body; and the gooseneck is connected with a cyclone (CN). Through arrangement of three smoke throats and wind and coal in three tangential directions, smoke, material powder and coal powder form three times of spouting effects and three cyclone effects inside the furnace and an overlapping effect of spouting and cyclone, the concentration of the material powder in airflow inside the furnace is far higher than the inlet or outlet concentration, the material-gas ratio inside the furnace is improved, the stay time of the material powder and coal powder inside the furnace is greatly prolonged, the heat exchange efficiency is further improved, and the burnout rate of the coal powder is improved. The spouting-cyclone overlapping multi-point material feeding recycling type decomposing furnace is suitable for new construction and improvement of an existing cement preheating pre-decomposing system, and can also be applied to a powdery material heat exchange system in metallurgy and chemical industries.
