摘要： In a process for preparing granular calcium hypochlorite particles, wherein hydrated triple salt crystals of calcium hypochlorite, sodium hypochlorite, and sodium chloride are reacted with a chlorinated lime slurry to form particles of calcium hypochlorite dihydrate, the resulting slurry is processed to separate the calcium hypochlorite dihydrate particles and the resulting particles are dried to form granular calcium hypochlorite particles, the improvement which comprises:a. continuously feeding triple salt crystals and a chlorinated lime slurry to a paste reactor containing an aqueous paste slurry of calcium hypochlorite dihydrate particles to form additional aqueous paste slurry of calcium hypochlorite dihydrate particles,b. continuously removing a portion of the paste slurry from the paste reactor,c. continuously dividing the removed portion of paste slurry into a first part and a second part,d. continuously recycling said first part of the paste slurry to the paste reactor,e. separating said second part into particles of calcium hypochlorite in the form of a wet cake and a resulting clarified mother liquor, andf. drying said wet cake to form granular particles of calcium hypochlorite.
