The present invention provides a device for smelting and regenerating phosphogypsum using high-temperature ceramsite and method for using same, where a rotary kiln is used to accept high-temperature ceramic granules that have been calcined and formed. The residual heat of the high-temperature ceramic granules allows them to be fully mixed with the phosphogypsum. On one hand, the high temperature of the ceramic granules achieves high-temperature dehydration of the phosphogypsum. On the other hand, the porous adsorption property of the ceramic granules can facilitate full absorption of some harmful substances in the phosphogypsum, thereby realizing the purification of the phosphogypsum. In addition, because the dehydrated phosphogypsum is generally in a suspended state, the rotary kiln of the present invention is equipped with a discharge outlet at the end. The discharge outlet uses a combination of a cyclone dust aspirator and a baghouse dust collector, which can draw out the phosphogypsum that has been fully dehydrated and is suspended in the rotary kiln, thereby realizing its complete collection without any leakage and achieving zero pollution.
A device for smelting and regenerating phosphogypsum using high-temperature ceramsite, comprising a rotary kiln, a cyclone dust aspirator, and a baghouse dust collector, wherein the rotary kiln is equipped with a feed inlet for input of phosphogypsum and ceramic granules, the rotary kiln is arranged in a tilted position, and a driving wheel is provided outside the rotary kiln, wherein the driving wheel is connected to a motor to drive rotation of the rotary kiln, an inner cylindrical surface of the rotary kiln is equipped with a stirring scraper, the stirring scraper is evenly arranged spirally on the inner cylindrical surface of the rotary kiln, the rotary kiln is in communication with the cyclone dust aspirator through a conveying pipe, and a tail end of the cyclone dust aspirator is in communication with the baghouse dust collector.
