style="text-indent:25px">間接冷卻式汽水取樣冷卻裝置的應(yīng)用：小型火力發(fā)電廠經(jīng)常采用一種簡(jiǎn)易的汽水取樣冷卻裝置,直接用循環(huán)水或工業(yè)水作為冷卻介質(zhì),用作鍋爐爐水,過熱蒸汽和飽和蒸汽等取樣器的冷卻.往往由于循環(huán)水或工業(yè)水水質(zhì)較差,很容易導(dǎo)致取樣冷卻器冷卻管結(jié)垢,堵塞,嚴(yán)重影響使用壽命,從而也影響到水質(zhì)化驗(yàn)結(jié)果,給鍋爐運(yùn)行埋下安全事故隱患,為了解決這一問題,本文介紹一種間接冷卻式取樣冷卻裝置,從而保證了取樣冷卻裝置內(nèi)部冷卻管可以**結(jié)垢,保證了它的可靠使用.連云港鍋爐取樣冷卻裝置廠家電動(dòng)操作，在外部備有電動(dòng)執(zhí)行機(jī)構(gòu)，并備有手動(dòng)機(jī)構(gòu)，有定時(shí)、點(diǎn)操、手動(dòng)三種功能。</p><div

（2）靜壓平衡型：靜壓平衡型等速取樣管由采樣管人口配置的專門采樣嘴(在嘴內(nèi)外壁上分別開有測(cè)量靜壓的條縫)，調(diào)節(jié)采樣流量使采樣嘴內(nèi)、外條縫處?kù)o壓相等，達(dá)到等速采樣條件，采樣孔插入流場(chǎng)中，使采樣嘴置于測(cè)點(diǎn)上，正對(duì)氣流，抽取一定量的氣體。根據(jù)采樣管濾筒上所捕集到的顆粒物量和同時(shí)抽取的氣體量，計(jì)算出其中的粉塵含量。當(dāng)被測(cè)煙道濕度大、煙塵濃度高時(shí)，靜壓孔容易被粘堵，影響等速采樣。 </p> <p> （3）動(dòng)壓平衡型：采樣的同時(shí)實(shí)時(shí)測(cè)量流場(chǎng)中的動(dòng)壓和采樣管內(nèi)氣流動(dòng)壓，調(diào)節(jié)控制采樣管內(nèi)外動(dòng)壓相等（即速度相等），達(dá)到等速取樣的目的。 </p> <p> 比較以上幾種原理可以看出，動(dòng)壓平衡型從原理上比較可靠，但結(jié)構(gòu)也比較復(fù)雜。它需要測(cè)管內(nèi)外動(dòng)壓，并進(jìn)行比較平衡，調(diào)整操作難度大。 </p> <p> 在動(dòng)壓平衡型等速采樣管原理基礎(chǔ)上，采用不會(huì)被粉塵堵塞的大口徑靠背管測(cè)量流場(chǎng)動(dòng)壓，算出流速，用流量計(jì)控制采樣管流速與流場(chǎng)速度相等，簡(jiǎn)化了操作。動(dòng)壓的測(cè)量采用了差壓變送器和計(jì)算機(jī)數(shù)據(jù)采集系統(tǒng)，流速和流量的測(cè)量采用計(jì)算機(jī)計(jì)算和顯示，采樣流量的控制采用手動(dòng)調(diào)節(jié)，實(shí)現(xiàn)了半自動(dòng)化取樣采集。
