AI Technical Summary
Technical Problem
目前，现有排风设备主要由进风管、过滤吸附箱、出风管和风机组成，由于过滤吸附箱处理通道单一，导致在过滤吸附部件达到饱和后，需要停机更换，如此不仅耽误处理效率，且直接更换安全性较差，存在非常大的辐射风险
Benefits of technology
[0016]1、该放射性废气排风系统，其一，通过多个过滤室并列设置，可以在不停机的情况下更换初效过滤板和活性炭过滤板。其二，对于雨天或潮湿地区来说，该环境容易使活性炭粘结而影响吸附效率和寿命，本申请通过在过滤室下方设置加热器，可以通过加热产生热气上升来使活性炭保持干燥，延长了过滤板使用寿命，而通过初效过滤板和活性炭过滤板配合，有效保证了活性炭过滤板的过滤效果，使其至少能保证90天(待处理放射性物质的衰变期)以上进行有效过滤，如此就可以先在衰变期满后安全更换过滤板，后切换过滤室持续处理放射性废气。其三，通过远程控制器来控制第一电动阀和第二电动阀切换，可以避免人员接近箱体，进而避免了被辐射风险，等到衰变期满后进行更换会更加安全，大大降低了更换人员被辐射风险。其四，本申请过滤板采用抽插定位方式，更换速度会非常快，缩减了更换人员接触箱体的时间，进而有助于进一步降低被辐射风险。
