河南電廠用氣力輸送泵-煤粉干粉輸送設備料封泵
在(zai)我*粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)運輸過程(cheng)中(zhong)，離不(bu)開氣力(li)(li)輸送設(she)備(bei)的(de)(de)參(can)與(yu)，而氣力(li)(li)輸送設(she)備(bei)的(de)(de)質量和技術含量也直接(jie)影響著(zhu)粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)的(de)(de)利用率。粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)是(shi)從煤(mei)(mei)炭燃燒后(hou)煙氣中(zhong)收集的(de)(de)細灰(hui)(hui)(hui)(hui)，是(shi)燃煤(mei)(mei)電廠排放的(de)(de)主要(yao)固體(ti)廢物。隨著(zhu)電力(li)(li)工業(ye)的(de)(de)發(fa)展，燃煤(mei)(mei)電廠粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)排放量逐(zhu)年增加。大(da)量的(de)(de)粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)如(ru)果(guo)不(bu)經處理，會產生(sheng)粉(fen)(fen)塵，污染大(da)氣，對人類和生(sheng)物體(ti)造(zao)成(cheng)危害(hai)。由于其特殊(shu)性能，粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)可在(zai)建材行業(ye)用作(zuo)混(hun)凝土的(de)(de)添(tian)加劑。正確(que)的(de)(de)應用不(bu)僅可以解決粉(fen)(fen)煤(mei)(mei)灰(hui)(hui)(hui)(hui)造(zao)成(cheng)的(de)(de)污染，而且也是(shi)另一(yi)個財(cai)富的(de)(de)來(lai)源。
新型粉體氣力輸送機是一種(zhong)利(li)用(yong)空(kong)氣(qi)輸(shu)送(song)(song)(song)(song)介(jie)質和動(dong)力(li)的(de)氣(qi)力(li)輸(shu)灰(hui)系(xi)(xi)統(tong)(tong)。可以使粉煤(mei)(mei)灰(hui)在輸(shu)送(song)(song)(song)(song)過程中保持干燥狀態，保持粉煤(mei)(mei)灰(hui)的(de)活(huo)性(xing)不變，有利(li)于粉煤(mei)(mei)灰(hui)的(de)合成。影響(xiang)。高(gao)(gao)壓低速流態化(hua)稀相氣(qi)力(li)輸(shu)送(song)(song)(song)(song)（固氣(qi)質量比大于10）飛灰(hui)系(xi)(xi)統(tong)(tong)突破(po)了(le)其他形式(shi)氣(qi)力(li)輸(shu)灰(hui)系(xi)(xi)統(tong)(tong)在輸(shu)送(song)(song)(song)(song)距(ju)離(li)、輸(shu)送(song)(song)(song)(song)濃(nong)(nong)度等(deng)方面的(de)限制.，氣(qi)源設(she)備簡(jian)單，輸(shu)送(song)(song)(song)(song)濃(nong)(nong)度高(gao)(gao)。高(gao)(gao)（固氣(qi)質量比可達30）、輸(shu)送(song)(song)(song)(song)速度低（約(yue)7rn/s）、輸(shu)送(song)(song)(song)(song)距(ju)離(li)長（可達1km以上）、輸(shu)送(song)(song)(song)(song)管徑(jing)小、投資成本(ben)低、運(yun)行成本(ben)低、操(cao)作維(wei)護簡(jian)單、操(cao)作方便、運(yun)行可靠(kao)等(deng)特點有利(li)于火(huo)電廠粉煤(mei)(mei)灰(hui)的(de)綜合應用(yong)。
粉體輸(shu)(shu)(shu)送(song)(song)料(liao)封泵是(shi)采用(yong)低(di)壓連(lian)續(xu)氣力(li)輸(shu)(shu)(shu)送(song)(song)方式輸(shu)(shu)(shu)送(song)(song)粉狀物(wu)料(liao)的(de)設備(bei)(bei)(bei)。它采用(yong)正(zheng)壓氣力(li)輸(shu)(shu)(shu)送(song)(song)來輸(shu)(shu)(shu)送(song)(song)粉狀物(wu)料(liao)。輸(shu)(shu)(shu)送(song)(song)管道(dao)(dao)可根據具體地形布置，實現集中、分(fen)散、高精度、長距離輸(shu)(shu)(shu)送(song)(song)。運(yun)輸(shu)(shu)(shu)過(guo)程中不受氣候條件影響，有利于生產和(he)環境保護。該設備(bei)(bei)(bei)配備(bei)(bei)(bei)自動化操(cao)作控(kong)(kong)制臺，可實現手動和(he)自動控(kong)(kong)制。自動控(kong)(kong)制采用(yong)繼電器或微機形式。該設備(bei)(bei)(bei)結(jie)構簡(jian)單(dan)，操(cao)作方便(bian)，所需操(cao)作量少，可連(lian)續(xu)給灰，并可自動調(diao)節產量，非常(chang)*。達到送(song)(song)灰的(de)效果。其(qi)特(te)點(dian)是(shi)輸(shu)(shu)(shu)灰介質壓力(li)較低(di)，設備(bei)(bei)(bei)管道(dao)(dao)閥門不易(yi)磨損，設備(bei)(bei)(bei)造價比(bi)其(qi)他輸(shu)(shu)(shu)送(song)(song)設備(bei)(bei)(bei)低(di)，后期(qi)運(yun)行(xing)基本不需要維護。另外，粉體氣力(li)輸(shu)(shu)(shu)送(song)(song)設備(bei)(bei)(bei)的(de)總體優點(dian)是(shi)結(jie)構簡(jian)單(dan)、運(yun)行(xing)可靠、性能穩定、耐磨性強(qiang)、運(yun)行(xing)成本低(di)。現已(yi)廣(guang)泛(fan)應(ying)用(yong)于電廠粉煤灰、水(shui)泥(ni)、水(shui)泥(ni)生料(liao)等粉體輸(shu)(shu)(shu)送(song)(song)領域。
