Abstract
The utility model discloses an environmentally-friendly and energy-saving fluidized-bed oxidation reactor. Flue gas exhausted from a flue gas outlet undergoes heat exchange with cold compressed air through a flue gas heat exchanger, and heated compressed air enters a tower body for participating in a reaction, so that energy can be saved, and the temperature of potassium hydroxide entering from a feeding hole is between 350 DEG C and 400 DEG C. If compressed air is added into the tower body, the temperature difference between two materials is large, internal pressure of the tower body is high, reaction is drastic, and material impact and the like occur easily. In the environmentally-friendly and energy-saving fluidized-bed oxidation reactor, the compressor air is heated by the flue gas, so that the temperature difference between a material on a feeding hole and the compressed air is reduced, the internal pressure of the tower is lowered, and a reaction is uniform. Waste gas with high water vapor content is mixed with heat-exchanged flue gas in a waste gas and flue gas mixing tower, so that dust in the flue gas is washed off, sulfur dioxide in the flue gas can be washed off, and waste residues are collected into a waste residue collecting tank for centralized treatment.
