移動式粉煤(mei)取樣(yang)器概述
?

連云港靈動機電設備有限公司所生產制造的手動移動式粉煤取樣器也可稱為便攜式煤(mei)粉取樣器主要用于正壓直吹式制粉系統-次風煤粉管上定期煤粉取樣。

由于磨煤機碾磨件的磨損、煤種、塊度的變化，煤粉細度將產生較大的變化，并直接影響鍋爐燃燒的-率，因此定期對煤粉細度取樣-測，當煤粉的細度遙遙過設計值時，及時調整分離器折向門開度，或-換碾磨部件是十分-要的。

移動式粉(fen)煤(mei)取(qu)(qu)樣器(qi)采(cai)用以(yi)壓(ya)(ya)(ya)縮空(kong)(kong)氣(qi)為(wei)動力(li)-，用射氣(qi)抽(chou)氣(qi)器(qi)將分離器(qi)內(nei)抽(chou)吸成負壓(ya)(ya)(ya)原(yuan)理(li)取(qu)(qu)樣，同時還具(ju)有反吹掃功能，避-了取(qu)(qu)樣口堵塞問(wen)題的(de)出(chu)現，且易(yi)于(yu)取(qu)(qu)樣。取(qu)(qu)樣的(de)速(su)度通過調整壓(ya)(ya)(ya)縮空(kong)(kong)氣(qi)壓(ya)(ya)(ya)力(li)、流量而得(de)到控(kong)(kong)制。一般壓(ya)(ya)(ya)力(li)控(kong)(kong)制在0.05-0.1Mpa,這樣取(qu)(qu)樣才會(hui)具(ju)有代表(biao)-，能夠(gou)得(de)到較(jiao)遙遙的(de)煤(mei)粉(fen)細度值。

移動(dong)(dong)式粉煤取樣器(qi)(qi)在壓縮(suo)(suo)空(kong)氣閥(fa)后加裝調(diao)壓閥(fa)。因一般電廠提供(gong)的(de)壓縮(suo)(suo)空(kong)氣的(de)壓力在4~6Kg左右，單(dan)靠(kao)壓縮(suo)(suo)空(kong)氣閥(fa)來調(diao)節很難(nan)達到(dao)移動(dong)(dong)式粉煤取樣器(qi)(qi)所需的(de)工作(zuo)壓力，往往因壓力過(guo)大而取樣失真，沒有(you)代表-。

移動(dong)式(shi)粉(fen)(fen)(fen)(fen)煤(mei)(mei)取(qu)樣(yang)(yang)器工作(zuo)原理：移動(dong)式(shi)粉(fen)(fen)(fen)(fen)煤(mei)(mei)取(qu)樣(yang)(yang)器是利用(yong)壓(ya)(ya)縮(suo)空(kong)(kong)氣(qi)抽吸，是設備(bei)內部形(xing)成(cheng)負(fu)壓(ya)(ya)的(de)(de)原理，將煤(mei)(mei)粉(fen)(fen)(fen)(fen)從(cong)煤(mei)(mei)粉(fen)(fen)(fen)(fen)管(guan)(guan)(guan)道(dao)-吸出(chu)(chu)(chu)(chu)并進行固(gu)、氣(qi)分(fen)(fen)離而研制遙遙的(de)(de)。現(xian)(xian)結合煤(mei)(mei)粉(fen)(fen)(fen)(fen)取(qu)樣(yang)(yang)過程加以說(shuo)明。煤(mei)(mei)粉(fen)(fen)(fen)(fen)取(qu)樣(yang)(yang)過程-，所(suo)有閥門為開啟狀態，當壓(ya)(ya)縮(suo)空(kong)(kong)氣(qi)從(cong)出(chu)(chu)(chu)(chu)氣(qi)管(guan)(guan)(guan)噴出(chu)(chu)(chu)(chu)時，其射流作(zuo)用(yong)-然(ran)導致與(yu)取(qu)樣(yang)(yang)閥連通(tong)的(de)(de)管(guan)(guan)(guan)道(dao)處(chu)出(chu)(chu)(chu)(chu)現(xian)(xian)負(fu)壓(ya)(ya)，管(guan)(guan)(guan)內氣(qi)體被(bei)帶出(chu)(chu)(chu)(chu)。分(fen)(fen)離器和其底部的(de)(de)集粉(fen)(fen)(fen)(fen)瓶(ping)是-封(feng)連接，能(neng)與(yu)外(wai)部連通(tong)的(de)(de)唯--只有取(qu)樣(yang)(yang)頭和取(qu)樣(yang)(yang)管(guan)(guan)(guan)。所(suo)以負(fu)壓(ya)(ya)的(de)(de)出(chu)(chu)(chu)(chu)現(xian)(xian)促使煤(mei)(mei)粉(fen)(fen)(fen)(fen)管(guan)(guan)(guan)中的(de)(de)煤(mei)(mei)粉(fen)(fen)(fen)(fen)沿(yan)取(qu)樣(yang)(yang)管(guan)(guan)(guan)進入(ru)取(qu)樣(yang)(yang)裝置，煤(mei)(mei)粉(fen)(fen)(fen)(fen)在分(fen)(fen)離器-被(bei)-次分(fen)(fen)離，并進入(ru)集粉(fen)(fen)(fen)(fen)瓶(ping)，而氣(qi)體及少許(xu)細粉(fen)(fen)(fen)(fen)從(cong)分(fen)(fen)離器的(de)(de)上部出(chu)(chu)(chu)(chu)口(kou)經出(chu)(chu)(chu)(chu)氣(qi)管(guan)(guan)(guan)內的(de)(de)葉片作(zuo)二次分(fen)(fen)離后，被(bei)壓(ya)(ya)縮(suo)空(kong)(kong)氣(qi)帶出(chu)(chu)(chu)(chu)，并--送入(ru)煤(mei)(mei)粉(fen)(fen)(fen)(fen)管(guan)(guan)(guan)道(dao)，對(dui)工作(zuo)場所(suo)不產生污(wu)染。

增加吹掃閥的(de)作用是：在煤(mei)粉取(qu)(qu)(qu)樣(yang)(yang)(yang)-和(he)取(qu)(qu)(qu)樣(yang)(yang)(yang)后，關吹掃閥，開取(qu)(qu)(qu)樣(yang)(yang)(yang)閥又可以吹掃取(qu)(qu)(qu)樣(yang)(yang)(yang)管(guan)中的(de)殘(can)留(liu)在取(qu)(qu)(qu)樣(yang)(yang)(yang)管(guan)中的(de)煤(mei)粉進行吹掃，以防(fang)取(qu)(qu)(qu)樣(yang)(yang)(yang)管(guan)被煤(mei)粉堵塞。并保了取(qu)(qu)(qu)樣(yang)(yang)(yang)遙遙。
