style="text-indent:25px">氣力輸送技術(shù)在玻璃廠原料系統(tǒng)中的應(yīng)用：氣力輸送是一種借助空氣（或其它氣體）在密封的管道內(nèi)的流動來輸送固體物料的技術(shù)。隨著國家和企業(yè)對節(jié)能、環(huán)保、人員安全等方面的重視，氣力輸送技術(shù)在眾多行業(yè)的生產(chǎn)工藝過程都得到了普遍的應(yīng)用，國外玻璃行業(yè)原料系統(tǒng)已經(jīng)普遍采用氣力輸送技術(shù)，國內(nèi)玻璃行業(yè)氣力輸送的原料主要是純堿、芒硝等幾種輕質(zhì)原料，礦物原料采用氣力輸送的相對較少，相信隨著國產(chǎn)裝備水平的不斷進(jìn)步，氣力輸送技術(shù)將會逐漸取代傳統(tǒng)輸送設(shè)備如帶式輸送機(jī)、刮板輸送機(jī)、鏈?zhǔn)捷斔蜋C(jī)、螺旋輸送機(jī)等傳統(tǒng)的機(jī)械輸送系統(tǒng)。</p><p style="text-indent:25px">正壓密相氣力輸送系統(tǒng)介紹:該系統(tǒng)采用壓縮空氣源作為輸送介質(zhì)。物料在管道內(nèi)以較低速度、沙丘狀態(tài)、流態(tài)化或團(tuán)聚狀態(tài)輸送的方式稱為正壓密相輸送。一般采用的氣源為空氣壓縮機(jī)，也可采用高壓羅茨風(fēng)機(jī)，輸送壓力根據(jù)工況不同可0.1MPa～1.0MPa。根據(jù)輸送特性，系統(tǒng)也可分為正壓密相動壓式輸送和正壓密相栓塞輸送兩種方式。物料以中低速度沙丘狀態(tài)或流態(tài)化在管道中輸送的方式稱為密相動壓式輸送; 物料以較低速度以團(tuán)聚狀態(tài)在管道中輸送的方式稱為密相栓塞輸送。但對粒徑有一定分布的物料，沉積速度將是噎塞速度的2～6倍。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">密相輸送通常有如下組合：根據(jù)輸送物料的不同，和布置形式的不同，需進(jìn)行嚴(yán)格的氣力輸送計算。正壓系統(tǒng)有多種不同形式的輸送方式。其方式為：通過星形鎖氣器的給料方式，將排入管道中的物料輸入儲料庫。通過鎖氣器的給料方式，將排入管道中的物料輸入儲料庫。組合的負(fù)壓正壓輸送系統(tǒng)由負(fù)壓系統(tǒng)將近距離的多點(diǎn)物料輸送到集料斗中，再由集料斗下部設(shè)置的倉泵將物料輸入儲料庫或其它接收點(diǎn)。連續(xù)密相：多點(diǎn)供料，單點(diǎn)出料的輸送方式。物料在管線中輸送速度低于懸浮速度，是和輸送粉末和小顆粒的物料。在顆粒輸送量恒定時，降低氣速，管道中固體含量隨之增高。河北氣流氣力輸送系統(tǒng)銷售</p><p style="text-indent:25px">當(dāng)氣速降低到某一臨界值時，氣流已不能使密集的顆粒均勻分散。河南管道輸送氣力輸送系統(tǒng)設(shè)計</p><p style="text-indent:25px">輸送氣流速度對磨損的影響：輸送時氣流速度對管壁磨損的影響較大。如果其它條件相同。降低物料碰撞壁面速度或改變物料撞擊角，都能在很大程度上減少壁面磨損。由于磨損是粒子與管道內(nèi)壁的撞擊或摩擦造成的。因此，粒子的速度越大。撞擊或摩擦的能量就越大。磨損越嚴(yán)重。通常，磨損量可表示為輸送氣流速度的n次正比例增長關(guān)系。如果氣流的速度太低，則被輸送的物料就會沉積在管道中，堵塞管道。因此合理選擇氣流速度是保證系統(tǒng)正常工作的關(guān)鍵。在氣力輸送中，磨損量可大致考慮為與輸送氣流速度的3次方成正比。即：物料與管壁接觸時的相對速度越大。形成的接觸壓力越大．產(chǎn)生的接觸頻率越高，彎管管壁的磨損速度就越快。圖2表示了輸送粉煤灰時的氣流速度與磨損量關(guān)系。河南管道輸送氣力輸送系統(tǒng)設(shè)計</p></p><br
