- 中文摘要: 根據多次的實驗本系設計並裝置了一套放射性廢水低溫吸附處理的前導工廠,包括三部份:(一)去除水氣:由改裝除濕機、化學柱及一低溫預冷器組成。(二)吸附床:包括一支主要活性炭吸附柱及一支二級活性炭吸附柱。(三)冷媒系統:包括兩個四公升迪化瓶,內裝液態氮,作為冷卻活性炭之用,一液面自動控制器,以維持液態氮液面高度;及一個五十公升液氮貯存槽,以供補液氮的消耗。 上述系統建立在金山核能一廠的廢氣取樣室中,做了一連串的實驗,測量其對廢氣的吸附量隨時間增長情形及穩定性。並測量不同溫度與流速對放射性惰氣在活性炭中的吸附情形,與穿透量。包括氪與氙各同位素的溫度與吸附係數的關係曲線及流速與吸附係數的關係曲線,結果並予以分析與討論。
- 英文摘要: Based on the cummulated experim-eatal experiences on the measurementsof the off gas adsorption on activecharacoal at low temperature, we havedesigned a pilot plant which containingthree parts: (1) Moisture remover: including dehumidifier, chemical column and a liquid nitrogen precooler. (2) Adsorption beds: including one main charcoal bed and one secondary charcoal bed. (3) Cryogenic system: including two small dewar containing liquid nitrogen to cool the adsorption beds, a level cont- roller to automatically supply liquid nitrogen from storagd tank. The system is set up in the off-gas chemistry sampling by pass roomof Chiu-Shan Nuclear Power Plant, asequence of experiments have beenmeasured including temprature andvelocity of off gas effective of theadsorption coefficient, and the amountof break through.
