分離器和其底部的集粉瓶是密封連接，能與外部連通的進(jìn)口只有取樣頭和取樣管。所以負(fù)壓的出現(xiàn)促使煤粉管中的煤粉沿取樣管進(jìn)入取樣裝置，煤粉在分離器中被一次分離，并進(jìn)入集粉瓶，而氣體及少許細(xì)粉從分離器的.上部出口經(jīng)出氣管內(nèi)的葉片作二次分離后，被壓縮空氣帶出，并重新送入煤粉管道，對(duì)工作場(chǎng)所不產(chǎn)生污染。增加吹掃閥的作用就在于煤粉取樣前和取樣后，關(guān)吹掃閥,開取樣閥又可以吹掃取樣管中的殘留在取樣管中的煤粉進(jìn)行吹掃，連云港取樣冷卻裝置品牌，以防取樣管被煤粉堵塞。并保證取樣準(zhǔn)確具有典型性。 </p> <p> 而固定式粉煤取樣裝置，主要用于直吹式制粉系統(tǒng)一-次風(fēng)煤粉管上定期煤粉取樣。由于磨煤機(jī)碾磨件的磨損、煤種、塊度的變化，煤粉細(xì)度將產(chǎn)生較大的變化，并直接影響鍋爐燃燒的效率，連云港取樣冷卻裝置品牌，因此定期對(duì)煤粉細(xì)度取樣檢測(cè)，當(dāng)煤粉的細(xì)度超過設(shè)計(jì)值時(shí)，及時(shí)調(diào)整分離器折向]開度，或更換碾磨部件是十分必要的，連云港取樣冷卻裝置品牌。取樣冷卻器可以將爐水、蒸汽冷卻到（20-40度），便于操作人員安全取樣及達(dá)到介質(zhì)冷卻溫度。連云港取樣冷卻裝置品牌</p><div

而離管的中心越近煤粉通過量就越小，停留時(shí)間越短，管中心煤粉通過量可視為零。實(shí)踐證明煤粉取樣按等圓環(huán)面積法，所獲得的樣品相當(dāng)有有典型性。如圖所示等圓環(huán)面積法。<p> （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。
