粉體氣力輸送從工作(zuo)原理(li)上主要分為(wei)(wei)(wei)動壓(ya)(ya)輸送(song)(song)和(he)靜(jing)壓(ya)(ya)輸送(song)(song)；動壓(ya)(ya)輸送(song)(song)是將(jiang)氣(qi)(qi)體的壓(ya)(ya)力能轉化為(wei)(wei)(wei)做(zuo)功(gong)的動能，稱為(wei)(wei)(wei)懸(xuan)浮輸送(song)(song)，灰氣(qi)(qi)比(bi)小(xiao)于(yu)40，屬(shu)于(yu)稀相輸送(song)(song)。靜(jing)壓(ya)(ya)輸送(song)(song)是將(jiang)氣(qi)(qi)體的壓(ya)(ya)力能轉變(bian)為(wei)(wei)(wei)推力來做(zuo)功(gong)，稱為(wei)(wei)(wei)活塞流輸送(song)(song)或柱塞輸送(song)(song)。灰氣(qi)(qi)比(bi)大于(yu)40，屬(shu)于(yu)密相輸送(song)(song)。

       正壓(ya)稀(xi)相(xiang)氣(qi)力(li)輸(shu)送系(xi)統的(de)優點：1）整個輸(shu)送過程(cheng)密閉(bi)，受氣(qi)候和(he)環境條件影響較(jiao)(jiao)小，不僅改善了(le)工(gong)作環境，而且防止了(le)被輸(shu)送物料吸潮、結(jie)(jie)垢或混入其(qi)他雜質，從(cong)而保證輸(shu)送物料的(de)質量；2）設(she)備(bei)簡單(dan)，結(jie)(jie)構(gou)緊湊，工(gong)藝(yi)布置(zhi)靈活，占地面(mian)積小，輸(shu)送線選(xuan)型方便；3）輸(shu)送過程(cheng)中(zhong)可同時進(jin)行混合(he)、破碎、分級、干燥等，還可進(jin)行一定(ding)的(de)化學(xue)反應(ying)；4）系(xi)統內部處于(yu)正壓(ya)狀態，物料易于(yu)從(cong)排料口排出；5）易于(yu)實現整個系(xi)統的(de)集中(zhong)控(kong)制(zhi)和(he)自(zi)動化；6）由于(yu)含塵氣(qi)體不經(jing)過羅(luo)茨鼓(gu)風機(ji)，對風機(ji)的(de)磨損(sun)較(jiao)(jiao)小，設(she)備(bei)使(shi)用(yong)壽命更長。7）適用(yong)于(yu)物料從(cong)一點到多點的(de)分散輸(shu)送。
