【摘要】：加压是提高活性炭吸氡效率的有效途径之一,但加压又伴随着不利于氡吸附的温湿度变化。为此设计并构建了消除这些不利变化的活性炭高压吸附装置,模拟了5种活性炭吸附环境,研究了动态吸附系数与压力、温度、湿度的关系。实验结果表明,增加系统压力并降低相对湿度和吸附温度,活性炭吸附氡气的动态吸附系数得到成倍的提高,高压低温低湿状态(0.6 MPa,0℃,20%~24%)的动态吸附系数是常压常温常湿状态(0.1 MPa,28℃,54%~65%)的5倍。此研究为今后开展加压吸氡技术相关影响因素的系统研究和高效除氡装置的研制打下了基础。
[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，
