活性炭变压吸附法降低空气中的氡气

Reducing Radon in Air with Pressure Swing Adsorption of Activated Carbon

为解决活性炭连续降氡过程中的在线再生问题,建立了降低空气中氡气的活性炭变压吸附法。该方法通过两个活性炭床变换吸附与解吸的角色,实现了持续输出低氡空气的目的。利用该方法分别在解吸气流比(λ)值为30%、53%、75%的条件下,测量装置输出口的浓度随时间的变化,结果表明在λ值为75%时,活性炭实现了再生且系统达到了循环稳态。

Within the framework of EPICS （ Experimental Physics and Industrial Control System）, a heat loss software for the TMSR Molten - salt loop is developed. Using the real - time temperature measurement of the sectionalized Molten - salt loop, and the interface developed by CSS （ Control System Studio）, the heat loss software has been successfully run on the TMSR test loop. Besides, the real - time signal processing and moni- toring functions are accompanied. The heat loss software, together with the real - time signal processing and monitoring functions, supports the future development of the TMSR monitoring system and the safety operation of TMSR.
