style="text-indent:25px">根據(jù)顆粒在輸送管道中的密集程度，氣力輸送分為：負(fù)壓輸送：管道內(nèi)壓力低于大氣壓，自吸進(jìn)料，但須在負(fù)壓下卸料，能夠輸送的距離較短；優(yōu)點(diǎn)：設(shè)備投資、負(fù)荷較小。缺點(diǎn)：運(yùn)行流速高，管道磨損嚴(yán)重，磨損出現(xiàn)漏洞無法察覺。在水平管道中進(jìn)行稀相輸送時(shí)，氣速應(yīng)較高，使顆粒分散懸浮于氣流中。氣速減小到某一臨界值時(shí)，顆粒將開始在管壁下部沉積。此臨界氣速稱為沉積速度。這是稀相水平輸送時(shí)氣速的下限。操作氣速低于此值時(shí)，管內(nèi)出現(xiàn)沉積層，流道截面減少，在沉積層上方氣流仍按沉積速度運(yùn)行。，剩余的氣流及時(shí)排出室外，也避免現(xiàn)場(chǎng)產(chǎn)生太多的粉塵。</p><div
