【摘要】：加壓是提高活性炭吸氡效率的有效途徑之一,但加壓又伴隨著不利于氡吸附的溫濕度變化。為此設(shè)計(jì)并構(gòu)建了消除這些不利變化的活性炭高壓吸附裝置,模擬了5種活性炭吸附環(huán)境,研究了動態(tài)吸附系數(shù)與壓力、溫度、濕度的關(guān)系。實(shí)驗(yàn)結(jié)果表明,增加系統(tǒng)壓力并降低相對濕度和吸附溫度,活性炭吸附氡氣的動態(tài)吸附系數(shù)得到成倍的提高,高壓低溫低濕狀態(tài)(0.6 MPa,0℃,20%~24%)的動態(tài)吸附系數(shù)是常壓常溫常濕狀態(tài)(0.1 MPa,28℃,54%~65%)的5倍。此研究為今后開展加壓吸氡技術(shù)相關(guān)影響因素的系統(tǒng)研究和高效除氡裝置的研制打下了基礎(chǔ)。
[Abstract]:Pressure is one of the effective ways to improve the radon absorption efficiency of activated carbon, but the pressure is accompanied by the change of temperature and humidity which is not conducive to the adsorption of radon. In order to eliminate these adverse changes, a high pressure adsorption device for activated carbon was designed and constructed. Five kinds of activated carbon adsorption environments were simulated, and the relationship between dynamic adsorption coefficient and pressure, temperature and humidity was studied. The experimental results show that the dynamic adsorption coefficient of radon adsorbed by activated carbon is increased exponentially by increasing the pressure of the system and lowering the relative humidity and adsorption temperature. The dynamic adsorption coefficients of 0 鈩，
