粉體氣力輸送機輸送系統的原理、區別及應用領域
首先(xian)，正壓輸送(song)系(xi)統和負壓輸送(song)系(xi)統有兩個區(qu)別:**是輸送(song)原(yuan)理；第(di)二:適用范圍。
粉體氣力輸送機輸送(song)原(yuan)理: 負壓(ya)輸送(song)系統主要是通過輸送(song)系統末端的(de)引(yin)風裝置在運行過程中(zhong)形成負壓(ya)，這種負壓(ya)與外界的(de)壓(ya)力差一(yi)起(qi)成為輸送(song)的(de)動力。因為壓(ya)力差，外界的(de)空氣被(bei)吸入(ru)管道(dao)，我(wo)們(men)放進去的(de)物質隨(sui)著(zhu)空氣的(de)運動被(bei)帶入(ru)管道(dao)。同時，到(dao)達目(mu)的(de)地(di)后，將物質從(cong)空氣中(zhong)分離(li)收集，凈(jing)化(hua)空氣后排(pai)入(ru)大氣或(huo)回收利用。
正壓(ya)(ya)輸送(song)(song)(song)是輸送(song)(song)(song)系統(tong)(tong)前端風機(ji)的使用，也可以說(shuo)是起點。這種風機(ji)將(jiang)壓(ya)(ya)縮空(kong)氣(qi)(qi)引入輸送(song)(song)(song)管道，利用管道起點和終點的壓(ya)(ya)力(li)(li)差，使空(kong)氣(qi)(qi)在管道內(nei)流動，帶動物(wu)料運動。在正壓(ya)(ya)輸送(song)(song)(song)系統(tong)(tong)中，物(wu)料由進料裝(zhuang)置送(song)(song)(song)入輸送(song)(song)(song)系統(tong)(tong)，在輸送(song)(song)(song)端，物(wu)料與空(kong)氣(qi)(qi)分離。與負壓(ya)(ya)氣(qi)(qi)力(li)(li)輸送(song)(song)(song)系統(tong)(tong)相比，正壓(ya)(ya)輸送(song)(song)(song)系統(tong)(tong)比正壓(ya)(ya)輸送(song)(song)(song)系統(tong)(tong)具有更長(chang)的輸送(song)(song)(song)距離。
氣力輸送機適用(yong)范(fan)圍:負(fu)(fu)壓(ya)(ya)輸(shu)送(song)(song)(song)(song)主要用(yong)于集中輸(shu)送(song)(song)(song)(song)，即點(dian)對(dui)點(dian)輸(shu)送(song)(song)(song)(song)，如車間除塵、儲糧(liang)等優點(dian)。負(fu)(fu)壓(ya)(ya)輸(shu)送(song)(song)(song)(song)可以有效收集物(wu)(wu)料(liao)，物(wu)(wu)料(liao)不會進(jin)入(ru)大氣。這對(dui)于有毒材(cai)料(liao)的氣動輸(shu)送(song)(song)(song)(song)尤為(wei)重要。但由于真(zhen)空的影響，物(wu)(wu)料(liao)的距(ju)離受到限制(zhi)，壓(ya)(ya)降(jiang)的*限為(wei)0.044mpaf71。正壓(ya)(ya)輸(shu)送(song)(song)(song)(song)系(xi)統適用(yong)于分(fen)(fen)散輸(shu)送(song)(song)(song)(song)，即一點(dian)多(duo)點(dian)輸(shu)送(song)(song)(song)(song)。在管道中，物(wu)(wu)料(liao)可以在任意卸載點(dian)通(tong)過物(wu)(wu)料(liao)和輸(shu)送(song)(song)(song)(song)介質的重力進(jin)行分(fen)(fen)離。
