Alkali decomposition reactor for producing zirconium chemical products by alkali fusion

The utility model relates to an alkali decomposition reactor for producing zirconium chemical products by an alkali fusion method. In the utility model, a bottom part forms an arc shape, and the ratio of the height H to the width S of the reactor is 1.0 < = H: S < = 1.5. The reactor with the structure has the advantages that distribution is uniform when a reaction occurs for the materials, the materials are agitated in a circulating manner, the decomposition rate of zircon is enhanced, material discharging intensity is reduced, and products of decomposition go into the water immersion process step without requirements for pulverization. The utility model overcomes waste of manpower and energy consumption, wherein, the waste of manpower and energy consumption is caused by that block shaped objects which are produced by the existing reactors require pulverization.
