  • VACUUM DEHYDRATING SYSTEM AND DEHYDRATING METHOD FOR GYPSUM SLURRY
    Publication number: 20110024363
    Abstract: The invention provides a vacuum dehydrating system for gypsum slurry, comprising a vacuum dehydrating apparatus, a first water supply apparatus for supplying filter cake washing water to the vacuum dehydrating apparatus, and a water heating apparatus for heating the filter cake washing water. The invention also provides a vacuum dehydrating method, comprising the following steps: 1) heating the filter cake washing water by the water heating apparatus; 2) supplying the heated filter cake washing water to a vacuum dehydrating apparatus during dehydrating the gypsum slurry by the vacuum dehydrating apparatus. In the invention, the filter cake washing water is heated. Due to the higher temperature of filter cake washing water, the dehydration rate of gypsum slurry is improved so that water content of gypsum filter cake after dehydration is decreased.
