Separation Technology and Application of Evaporation Tower in Boron Recycle System of Nuclear Power Plant
To realize independent design of evaporation tower of boron recycle system of nuclear power plant,theoretical calculation model of evaporation tower tray separation was established based on separa-tion theory,evaporator separation level of boron water of boron acid solution was analyzed,and small scale experimental device was used for test verification and analysis.Meanwhile,the calculation method of entrainment rate of entrainment of evaporation chamber in evaporation tower bottom was analyzed and given.The proposed theoretical calculation model was used for the design of evaporation equipment in bo-ron recycle system.The results show that the numerical results agrees well with the experimental result,indicating the correctness of seperation method adopted by theoretical analysis and calculation model.The designed boron recycle system can satisfy the field operation requirement of nuclear power plant with a high safety margin.
