鍋爐啟動初期的油灰或冷態(tài)灰不適合設(shè)計的輸送工況。7.因雨水侵入或噴水沖洗等原因使粉煤灰受潮粘結(jié)、顆粒增大，輸送時摩擦阻力增加而引起堵管。8.輸灰管或空氣母管上的閥門未全開，造成局部阻力過高或供氣不足。9.灰斗氣化不良，造成物料的流動性差。10，青海負(fù)壓稀相氣力輸送系統(tǒng)價格.除灰管內(nèi)有異物或大塊物料堵塞。11.空壓機在卸荷狀態(tài)下開泵輸送，而空壓機重新升荷需要一定的時間，造成在這一段時間內(nèi)系統(tǒng)供氣不足，使輸灰管內(nèi)的物料流速下降沉積而堵塞。物料在負(fù)壓下輸送，水分易于蒸發(fā)，因此對水分較高的物料，比壓送式易于輸送。青海負(fù)壓稀相氣力輸送系統(tǒng)價格</p><div

style="text-indent:25px">氣力輸送堵管有什么原因：堵管經(jīng)常發(fā)生在倉泵等發(fā)送器出口不到150m的起始段內(nèi)，這是因為起始段的流速低、濃度高、流態(tài)較不穩(wěn)定，隨著輸送過程中摩擦阻力對壓縮空氣能量的消耗，管內(nèi)壓力逐漸降低，比容增加，使壓縮空氣體積膨脹，流速增高，就不容易發(fā)生堵塞了，后段管道就是堵塞了也會自動疏通，因為后段管道由于控制過高的流速以防止磨損，往往采用擴徑設(shè)計，使管徑增大、濃度降低，初速也較前段設(shè)計的高，因此大粒子趨向沉積于管底，當(dāng)流速在一定的范圍內(nèi)時，管底流仍能繼續(xù)輸送；萬一出現(xiàn)栓塞，由于大粒子間的縫隙大，中間可有氣流通過，同時在栓塞后堵塞位置前部的壓力會上升而增加推壓料栓的靜壓力，從而使料栓崩潰而疏通，使輸送繼續(xù)進行下去。當(dāng)然在料栓崩潰時會引起壓力波動，產(chǎn)生振動和響聲，行話叫“放炮”。因此一方面在設(shè)計時應(yīng)合理控制輸送流速，另一方面還應(yīng)注意后段管道支架的強度，控制滑動支架的間隙，以免“放炮”時損壞支架和管道而造成事故。設(shè)備的制造、維護要求低，工人的可操作性強: 可以長距離輸送。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="青海負(fù)壓稀相氣力輸送系統(tǒng)價格,氣力輸送"

style="text-indent:25px">固氣比：對于一定粒度的物料，固氣比有一個較佳值，此值既能保證物料的輸送，又要保證用氣量較少。若固氣比高于較佳值，物料雖被輸送出去，但用氣量大，物料在輸送管道內(nèi)的流速高，物料對管道的磨損就變大。倉泵壓力下限/上限值設(shè)定倉泵壓力下限值的設(shè)定較為重要，若該值設(shè)定過大，泵內(nèi)或管道內(nèi)的物料未輸送完畢，會影響第二次輸送。若該值設(shè)定過小，泵內(nèi)或管內(nèi)的物料早已輸送完畢，會造成壓縮空氣浪費，延長輸送時間，降低輸送效率。一般將倉泵壓力下限值設(shè)定為倉泵輸送壓力加上0.01～0.03ＭPa。倉泵壓力上限值設(shè)定為倉泵實際輸送過程中的壓力加上0.02～0.04ＭPa。在輸送過程中還可同時進行物料的加熱、冷卻、干燥和氣流分級等物理操作或某些化學(xué)操作。貴州正壓稀相氣流氣力輸送機</p><p
