STATION FOR COMBINED UTILISATION OF SOLID WASTE AND SEWAGE CONTAMINATED BY RADIOACTIVE COMPONENTS Russian patent published in 2008 - IPC G21F9/00 

FIELD: physics, nuclear physics.

SUBSTANCE: invention concerns utilisation of organic-containing waste contaminated by radioactive components (overalls, filters, flush water etc.) obtained in technological processes. Station for combined utilisation of solid waste and sewage contaminated by radioactive components includes thermal reactor, cyclone furnace, catalytic afterburner, shell and tube heat exchanger, gas treatment system, and exhaust fan. Thermal reactor includes heating chamber with thermal destruction chamber positioned inside. Thermal destruction chamber features waste loading and coke ash content discharge devices. Cyclone furnace features burner. The station also includes gas distributor and horizontal evaporation pan. Gas distributor is positioned at the inlet of shell and tube heat exchanger. Evaporation pan bottom includes fumivorous channel system. Channels inlet is connected to gas distributor, while outlet is connected to gas treatment system inlet. Side walls of evaporation pan can feature overflow slits maintaining certain fluid level in the pan to meet requirements of nuclear safety.

EFFECT: combined utilisation of solid waste and sewage containing radioactive components without the use of additional thermal energy sources, and meeting nuclear safety requirements.
