9、630.73GB 5832.2-86 氣體中微量水分的測(cè)定-露點(diǎn)法i 適用范圍本標(biāo)準(zhǔn)適用于氧、氮、氫、氦、氖、氬、氪、氙、二氧化碳等氣體中微量水分露點(diǎn)的測(cè)定。其測(cè)量范圍 0C? -70C原理術(shù)語說明水分露點(diǎn)一一在恒定的壓力下，氣體中的水蒸氣達(dá)到飽和時(shí)的溫度。方法原理本法用露點(diǎn)儀進(jìn)行測(cè)定。使被測(cè)氣體在恒定壓力下，以一定的流量流經(jīng)露點(diǎn)儀濺定室中的拋光金屬鏡面。該鏡面的溫度可人為地降低并可精確 地測(cè)量。當(dāng)氣體中的水蒸氣隨著鏡面溫度的逐漸降低而達(dá)到飽和時(shí)，鏡面上開始出現(xiàn)露，此時(shí)所測(cè)量到的鏡面溫度即為露點(diǎn)。 （ 由露點(diǎn)和氣體中水分含量的換算式或查表，即可得到氣體中微量水分含量。 ）儀器概述儀器可以用不同

10、的方法設(shè)計(jì)，主要的不同在于金屬鏡面的性質(zhì)、用于冷卻鏡面的方法、如何控制鏡面的溫度、測(cè)定溫 度的方法以及檢測(cè)出露的方法。鏡子和它的附件通常安放在氣體樣品流經(jīng)的測(cè)定室中。儀器的一般要求提供下述裝置、滿足基本要求的任何露點(diǎn)儀都可以使用。當(dāng)儀器溫度高于氣體中水分露點(diǎn)至少2C 時(shí)，可以控制氣體進(jìn)出儀器的流量。把流動(dòng)的樣品氣冷到足夠低的溫度，使得水蒸氣能凝結(jié)，冷卻的速度可調(diào)。能觀察露的出現(xiàn)和準(zhǔn)確地測(cè)量露點(diǎn)。氣路系統(tǒng)死體積小且氣密性好，露點(diǎn)室內(nèi)氣壓應(yīng)接近大氣壓力。用標(biāo)準(zhǔn)樣衡量儀器是否符合要求，按GB 4471-84 化工產(chǎn)品試驗(yàn)方法精密度室間試驗(yàn)重復(fù)性和再現(xiàn)性的確定第 4.3 條進(jìn)行。目視和光電露點(diǎn)儀簡單的

11、露點(diǎn)儀以手動(dòng)調(diào)節(jié)冷量，控制鏡面降溫速度，用目視法觀察露的生成。該法憑經(jīng)驗(yàn)操作，人為誤差較大。采用 光電系統(tǒng)確定露生成的光電露點(diǎn)儀有相當(dāng)高的準(zhǔn)確度和精密度；用戶按需要和可能進(jìn)行選擇。露的觀察目視露點(diǎn)儀用肉眼觀察露的出現(xiàn)。光電露點(diǎn)儀是采用裝在測(cè)定室的光源照射鏡面，光源和光電池能以各種方式排列， 當(dāng)鏡面未結(jié)露時(shí)，無散射發(fā)生，硅光電池上沒有光照，鏡面上結(jié)露后，入射光在鏡面發(fā)生散射，一部分光照射到硅光電池上 從而產(chǎn)生光生電壓，給出出露信號(hào)。鏡面制冷方法用下述方法來降低和調(diào)節(jié)鏡子溫度，其中 3.5.1 和 3.5.2 所介紹的方法要求操作人員注意觀察而不適用于自動(dòng)裝置。對(duì)自動(dòng)裝置，使用兩種方法制冷： 3.

12、5.3 和 3.5.4 所介紹的液化氣體制冷及熱電效應(yīng)制冷。溶劑蒸發(fā)制冷用一種揮發(fā)性液體與鏡子背面接觸，用通入低壓空氣或其他壓縮氣體鼓泡的辦法使液體氣化而制冷。絕熱膨脹法制冷讓一種氣體通過噴嘴后流過鏡子背面，由于氣體發(fā)生膨脹而使鏡面冷卻，這種氣體通常用鋼瓶裝壓縮二氯化碳，也可 以使用壓縮空氣和壓縮氮?dú)獾取１痉ㄖ辽倌苁圭R面溫度下降40C。液化氣體制冷目前廣泛使用液化氣體作冷卻劑。如用液氮可獲得-80C或更低的溫度。當(dāng)用液化氣體制冷時(shí)，可以使和鏡子背面相接觸的銅棒與液化氣體直接接觸、或通過電熱方法使液化氣體氣化來制冷，也可以使壓縮氣體通過液氮浸泡著的盤管冷卻后制 冷。用熱電 （ 珀?duì)柼?） 效應(yīng)制

13、冷該法也就是半導(dǎo)體制冷，采用多級(jí)串聯(lián)獲得不同的低溫。溫度測(cè)量應(yīng)盡可能準(zhǔn)確地測(cè)量出露時(shí)鏡面的溫度，為了避免鏡面上的溫度差異，應(yīng)使用高熱導(dǎo)性的鏡子，一般采用金、銅、不銹鋼和銠合金。測(cè)量露點(diǎn)溫度，使用精密水銀溫度計(jì)、熱電偶、熱敏電阻或鉑電阻感溫元件。目前，高精度測(cè)量都采用鉑電阻感溫元件。分析前的準(zhǔn)備試漏測(cè)試系統(tǒng)所有接頭處應(yīng)無泄漏，否則會(huì)由于空氣中水分的滲入而使測(cè)量結(jié)果偏高。簡單的試漏方法如下：將盛有水的 u 型壓力計(jì)接在儀器的氣體出口處，調(diào)節(jié)氣路壓力，使u 型管內(nèi)壓差為 1000mm 2O ，關(guān)閉氣源，經(jīng)5min 水柱下降不超過5mm 說明系統(tǒng)氣密性良好。必要時(shí)，應(yīng)升高壓力試漏。若發(fā)現(xiàn)系統(tǒng)漏氣，則應(yīng)

14、分段檢查解決。取樣設(shè)備取樣閥：用死體積小的調(diào)節(jié)閥，如針形閥。取樣管：原則上采用盡可能短的小口徑管子，一般使用長度不超過2m, 內(nèi)徑不大于4mm 勺不銹鋼管或壁厚不小于 1mm 的聚四氟乙烯管，使用前洗凈，再吹干或烘干。不允許用橡皮管。取樣閥的吹洗徽開取樣閥，開啟鋼瓶頂閥后立刻關(guān)閉。開大取樣閥待放出的氣流變小時(shí)關(guān)小取樣閥，再開啟鋼瓶頂閥后立刻關(guān)閉， 如此反復(fù)三次，再 進(jìn)行測(cè)定。流量計(jì)的標(biāo)定應(yīng)針對(duì)不同氣樣，用皂膜流量計(jì)標(biāo)定樣品氣的測(cè)試流量。一般操作步驟用氣體吹洗管道和測(cè)定室。對(duì)放置后剛啟用的儀器，當(dāng)待測(cè)氣體中水分露點(diǎn)約為 -60 C 時(shí)，應(yīng)吹洗2h 后才能進(jìn)行測(cè)定。調(diào)節(jié)樣品氣流量至規(guī)定范圍內(nèi)。開始

15、制冷，當(dāng)鏡面溫度離露點(diǎn)約 5C 時(shí)，降溫速度應(yīng)不超過5C/min ，對(duì)不知道露點(diǎn)范圈的樣品氣，可先進(jìn)行一次粗測(cè)。停機(jī)后，樣品氣的進(jìn)出口擰上密封螺母。6.1 干擾物質(zhì)概述當(dāng)固體顆粒或灰塵等進(jìn)入儀器并附著在鏡面上時(shí)，用光電法測(cè)得的露點(diǎn)值將偏離I 除水蒸氣外的其他蒸氣也可能在鏡面上冷凝，使得所觀察到的露點(diǎn)不同于相應(yīng)的水蒸氣含量的露點(diǎn)。固體雜質(zhì)及油污如果固體雜質(zhì)絕對(duì)不溶于水，它們就不會(huì)改變露點(diǎn)，但是會(huì)妨礙出露的觀察。在自動(dòng)裝置中，對(duì)固體雜質(zhì)如果沒有采用補(bǔ)償裝置，在低露點(diǎn)測(cè)量時(shí)，有時(shí)會(huì)因鏡面上附著固體雜質(zhì)使測(cè)得的露點(diǎn)值偏高，這時(shí)應(yīng)該用脫脂棉蘸上無水乙醇或四氯化碳清洗鏡面。為了防止固體雜質(zhì)的干擾，儀器入口

16、要設(shè)置過濾器，而過濾器對(duì)氣體中水分應(yīng)無吸附。如果被測(cè)氣體中有油污，在氣體進(jìn)入測(cè)定室前應(yīng)該除去。以蒸氣形式存在的雜質(zhì)烴能在鏡面上冷凝，如果烴類露點(diǎn)低于水蒸氣露點(diǎn)，不會(huì)影響測(cè)定。在相反的情況下，會(huì)先于水蒸氣而結(jié)露，因此水蒸氣冷凝前必須分離出烴的冷凝物。如果被測(cè)氣體中含有甲醇，它將與水一起在鏡面上凝結(jié)，。這時(shí)得到的是甲醇和水的共同露點(diǎn)。冷壁效應(yīng)除鏡子外，儀器其余部分和管道的溫度應(yīng)高于氣體中水分露點(diǎn)至少2C,否則，水蒸氣將在最冷點(diǎn)凝結(jié)，改變了氣體樣品中水分含量。降溫速度如果氣體樣品中水分含量較低，冷卻鏡子時(shí)應(yīng)盡可能的慢。因?yàn)檫@時(shí)冰的結(jié)晶過程比較緩慢，若以不適當(dāng)?shù)乃俣冉禍?，在冰層生長和達(dá)到穩(wěn)定之前，還沒

17、有觀察到出露，溫度已大大超過了露點(diǎn)，這就是過冷現(xiàn)象。通常肉眼能觀察到的露大約是10-5 g/cm 2，用靈敏的光電露點(diǎn)儀，可檢測(cè)出很低的水分含量。用目視露點(diǎn)儀測(cè)定較低的水分含量時(shí)，應(yīng)采取下述措施t接近露點(diǎn)時(shí)，冷卻鏡子的速度應(yīng)盡可能慢。使用放大鏡觀察露的出現(xiàn)。當(dāng)鏡子溫度慢慢地降低，露剛出現(xiàn)時(shí)測(cè)得的溫度與鏡子溫度慢慢上升而露消失時(shí)測(cè)得的溫度之平均值作為露點(diǎn)。結(jié)果處理兩次露點(diǎn)測(cè)定結(jié)果的算術(shù)平均值為露點(diǎn)值，兩次露點(diǎn)溯定結(jié)果之差應(yīng)小于第 8 章中對(duì)重復(fù)性的規(guī)定。露點(diǎn)換算為 ppm （V/V） 按附錄 A （補(bǔ)充件 ） 中 A.1 計(jì)算或查表。露點(diǎn)換算為絕對(duì)濕度g/m3（20 C， 101.3kPa 下）
