Title:
APPARATUS FOR DISPOSING OF WASTE LIQUID GENERATED IN LOW/INTERMEDIATE-LEVEL RADIOACTIVE WASTE CARBONIZATION SYSTEM USING LOW-PRESSURE SUPERHEATED STEAM
Document Type and Number:
WIPO Patent Application WO/2019/004630
Kind Code:
A1
Abstract:
The present invention relates to a system for carbonizing low/intermediate-level radioactive wastes by using low-pressure superheated steam so as to reduce the volume thereof, and provides a low/intermediate-level radioactive waste carbonization system using low-pressure superheated steam, the system comprising: supply equipment for crushing, by means of a crusher, the low/intermediate-level radioactive wastes generated in a nuclear power plant and then supplying the same to a carbonization furnace; carbonization equipment for directly spraying the low-pressure superheated steam to the low/intermediate-level radioactive wastes so as to carbonize the same, then separate the same into carbonization byproducts and carbonized gas, and respectively discharge the same to a carbonization byproduct tank and a blower; heat source equipment having a saturated steam generator for producing the superheated steam and supplying the same to the carbonization furnace and a reheated steam generator, the multi-stage reheated steam generator for reheating the saturated steam generated in the saturated steam generator, so as to produce reheated steam of the predetermined temperature, and supply the same to the carbonization furnace, and the blower for supplying, to the reheated steam generator, circulating steam discharged from the carbonization furnace and the saturated steam produced in the saturated steam generator; cooling equipment for cooling, by means of air-cooled heat exchange, the high-temperature carbonized gas which has been generated and separated in the carbonization furnace; cleaning equipment for spraying cleaning liquid to the carbonized gas cooled in the cooling equipment, so as to separate, by means of droplets, liquid membranes, and bubbles, dust contained in the cooling equipment and collect the same; dehumidification equipment for removing moisture which is included in the carbonized gas having passed through the cleaning equipment and the heat generated in the cooling equipment due to heat exchange; and white smoke reduction equipment for removing, by means of HEPA filters provided in multiple stages, particulate matters and radioactive substances included in the carbonized gas from which the moisture has been removed in the dehumidification equipment, mixing the gas having passed through the cooling equipment and the gas having passed through the HEPA filters, and finally discharging the mixture thereof into the atmosphere.
