摘要
为提高活性炭的氡吸附效率以及为降低氡净化成本提供参考,研究了在主动吸附模式下,设置活性炭在不同气流比速的条件下进行氡吸附实验,测量活性炭的氡吸附量。杏壳活性炭与煤质活性炭的氡吸附量随气流比速度的增加,没有较大变化;气流比速在0.9~2.0 cm/s依次增大时,椰壳活性炭的氡吸附量没有较大变化。气流比速在2.0~3.1 cm/s依次增大时,椰壳活性炭的氡吸附量呈先增加后降低的趋势,当气流比速为2.7 cm/s左右时,椰壳活性炭氡吸附量达到峰值,可选取2.7 cm/s作为椰壳活性炭氡吸附的最佳气流比速。
In order to improve the radon adsorption efficiency of activated carbon and to reduce the purification cost of radon,this paper studied the radon adsorption experiment of activated carbon at different gas velocity under active adsorption mode,and measured the radon adsorption amount of activated carbon which was at different gas velocity.There was no significant change in the radon adsorption amount of apricot shell activated carbon and coal activated carbon with the increase of the gas velocity.When the gas velocity increased from 0.9 cm/s to 2.0 cm/s,there was no significant change in the radon adsorption amount of coconut shell activated carbon.When the gas velocity increases from2.0 cm/s to 3.1 cm/s,the radon adsorption by coconut shell activated carbon first increased and then decreased.When the gas velocity is about 2.7 cm/s,the radon adsorption amount of coconut shell activated carbon reaches a peak value.2.7 cm/s can be selected as the optimum gas velocity for the adsorption of radon from coconut shell activated carbon.
