研究建立了中国实验快堆钠火气溶胶的去除方法。方法采用湿式除尘器与干式过滤器相结合的方法,建立了一套实验装置。当钠气溶胶入口浓度大于7mg/L时,湿式除尘器的净化效率大于85%,而总的净化效率为96%±2%;当钠气溶胶的入口浓度大于1mg/L而小于7mg/L时,湿式除尘器的净化效率大于74%,而总净化效率为87%±2%;当入口气溶胶浓度小于1 mg/L时,湿式除尘器的净化效率为40%,而总的净化效率只有50%左右。气溶胶经过净化后,通风系统的出口气溶胶浓度小于0.5 mg/L。文章还对气溶胶的行为做了一些初步的研究。
Study to establish China Experimental Fast Reactor sodium fire aerosol removal method. Methods A set of experimental device was established by combining the wet filter and the dry filter. When the sodium aerosol inlet concentration is more than 7mg / L, the purification efficiency of the wet-type precipitator is more than 85% while the total purification efficiency is 96% ± 2%. When the sodium aerosol inlet concentration is more than 1mg / L and less than 7mg / L , The wet cleaning efficiency is above 74% and the total cleaning efficiency is 87% ± 2%. When the inlet aerosol concentration is less than 1 mg / L, the wet cleaning efficiency is 40%, while the total cleaning efficiency Only about 50%. After the aerosol has been purified, the ventilation system outlet aerosol concentration is less than 0.5 mg / L. The article also made some preliminary research on aerosol behavior.
