A PRECIPITATING RETRIEVAL AND DISSOLVING RECYCLE APPARATUS FOR EXCESS IODINE USED FOR THE PROCESS FOR THE PRODUCTION OF HYDROGEN USING SULFUR-IODINE PROCESS CONNECTED WITH VERY HIGH TEMPERATURE REACTOR(VHTR)

摘要

The present invention provides an excess iodine precipitation recovery and dissolution recycle apparatus including a cold precipitation crystallizer and a solid-liquid separator used in a sulfur-iodine thermochemical hydrogen production process associated with an ultra high temperature gas furnace (VHTR), and an excess iodine precipitation using the same. A recovery and dissolution recycle method. The device according to the invention is characterized in that two or more solid-liquid separators are capable of recovering and recycling the excess iodine contained in the process during continuous operation. According to the present invention, the fluid flow can be prevented from being disturbed by the iodine which is inevitably oversupplied for phase separation, and the energy consumption can be reduced during the distillation / concentration of the iodide solution.
