Title:
CRYSTALLIZATION REACTOR AND CRYSTALLIZATION REACTION METHOD
Document Type and Number:
Japanese Patent JP2009119382
Kind Code:
A
Abstract:
To provide a crystallization reactor which can reduce the level of ions contained in a recovered crystal of a hardly soluble salt.
This crystallization reactor is designed for producing the crystal of the hardly soluble salt by adding a crystallization agent to untreated water containing a substance to be crystallized. In addition, this reactor includes a crystallization reaction tank for producing the crystal of the hardly soluble salt by adding the crystallization agent to the untreated water, an extraction means for extracting at least, a part of slurry containing the crystal produced in the crystallization reaction tank, a dehydration means for dehydrating the extracted slurry, and a cleaning means for cleaning the dehydrated crystal.
