粉體氣力輸送機工作原理及特點
隨著(zhu)*球氣候變暖、空氣污染加劇等環境問(wen)題，人們(men)對(dui)新能源的開(kai)(kai)發(fa)利用(yong)提出(chu)了越(yue)來越(yue)高的要(yao)求。粉(fen)體(ti)(ti)(ti)(ti)輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)機是一種新型低壓稀相氣力輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)設備(bei)，又稱(cheng)粉(fen)體(ti)(ti)(ti)(ti)輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)機或粉(fen)體(ti)(ti)(ti)(ti)物(wu)料輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)泵(beng)。但由(you)于其傳(chuan)輸(shu)(shu)(shu)距離的限(xian)制，制約了其在(zai)大型火電廠長距離傳(chuan)輸(shu)(shu)(shu)條(tiao)件下(xia)的發(fa)展。這個(ge)問(wen)題需要(yao)進(jin)(jin)一步研究和完善。現在(zai)粉(fen)體(ti)(ti)(ti)(ti)輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)機行業已經開(kai)(kai)始(shi)快速(su)(su)發(fa)展。對(dui)粉(fen)體(ti)(ti)(ti)(ti)輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)機的研究在(zai)**各*都非常重(zhong)要(yao)。新技術(shu)層出(chu)不窮，其用(yong)途也不斷被(bei)(bei)(bei)開(kai)(kai)發(fa)。粉(fen)末輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)泵(beng)采用(yong)氣動壓差原理(li)和射流(liu)(liu)技術(shu)。結合(he)流(liu)(liu)態化(hua)技術(shu)，充分吸收現代氣力輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)理(li)論，是針對(dui)粉(fen)體(ti)(ti)(ti)(ti)氣力輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)工(gong)藝系(xi)統中大量連續輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)要(yao)求而(er)開(kai)(kai)發(fa)的專用(yong)設備(bei)。由(you)于工(gong)藝系(xi)統簡單，所(suo)配置的控制系(xi)統邏輯(ji)關系(xi)也簡單，操作(zuo)維(wei)護簡單可靠(kao)。粉(fen)體(ti)(ti)(ti)(ti)輸(shu)(shu)(shu)送(song)(song)(song)(song)(song)機由(you)擴(kuo)散(san)(san)(san)室、泵(beng)體(ti)(ti)(ti)(ti)、活(huo)動風道(dao)、執(zhi)行機構等部(bu)件組(zu)成。低壓空氣通過(guo)進(jin)(jin)氣管(guan)和泵(beng)體(ti)(ti)(ti)(ti)進(jin)(jin)入擴(kuo)散(san)(san)(san)室。當高速(su)(su)氣流(liu)(liu)通過(guo)泵(beng)體(ti)(ti)(ti)(ti)時，噴嘴周圍的物(wu)料被(bei)(bei)(bei)汽(qi)化(hua)。流(liu)(liu)出(chu)噴嘴并進(jin)(jin)入擴(kuo)散(san)(san)(san)室的氣流(liu)(liu)在(zai)噴嘴和擴(kuo)散(san)(san)(san)室之間形成局部(bu)負壓。汽(qi)化(hua)后的物(wu)料被(bei)(bei)(bei)吸入進(jin)(jin)料管(guan)，并被(bei)(bei)(bei)高速(su)(su)氣流(liu)(liu)提升至(zhi)卸料點。
