DEVICE FOR CONDENSING AND CLEANING STEAM-GAS MIXTURE PRIMARILY DURING ACCIDENTS AT NUCLEAR POWER PLANTS Russian patent published in 2004 - IPC

FIELD: nuclear power engineering; chemical, metallurgical, petrochemical, gas, and other industries. SUBSTANCE: device intended for cleaning steam or gas and also their mixtures has thin-walled vertical ferrule in the form of body of revolution disposed in drain tank yoke with water- and gas-outlet pipes, its hollow incorporating tangential steam-gas mixture inlet. The latter is made in the form of tangential scroll case enclosing external part of ferrule with perforated holes. Ferrule is installed in a spaced relation to tank bottom and drain tank is provided with means for condensate storage whose free surface level is above upper level of ferrule perforated holes and below its upper end. EFFECT: augmented steam condensation, enhanced amount of radionuclides and foreign inclusions entrapped, extended operating range and facilitated manufacture of device. 5 cl, 2 dwg
