輸(shu)(shu)(shu)(shu)(shu)灰雙(shuang)套管(guan)規(gui)(gui)格(ge)濃相輸(shu)(shu)(shu)(shu)(shu)送(song)(song)系(xi)統(tong)(tong)(tong)(tong)(tong)采用較低(di)(di)的輸(shu)(shu)(shu)(shu)(shu)送(song)(song)速(su)(su)度(du)(du)(du)(du)，起始速(su)(su)度(du)(du)(du)(du)為(wei)4-6m/s，末速(su)(su)為(wei)10-12m/s。高速(su)(su)磨損是氣(qi)力輸(shu)(shu)(shu)(shu)(shu)送(song)(song)較難解(jie)決的一個難題。由于(yu)氣(qi)固兩相流(liu)的特(te)殊(shu)性，常(chang)規(gui)(gui)的系(xi)統(tong)(tong)(tong)(tong)(tong)計算流(liu)速(su)(su)是以(yi)空氣(qi)流(liu)速(su)(su)為(wei)依(yi)據，而無(wu)法(fa)真正(zheng)(zheng)確(que)定物(wu)(wu)料(liao)(liao)的流(liu)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)，但從(cong)系(xi)統(tong)(tong)(tong)(tong)(tong)輸(shu)(shu)(shu)(shu)(shu)送(song)(song)機(ji)理(li)可判斷(duan)其(qi)物(wu)(wu)料(liao)(liao)的運(yun)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)，常(chang)規(gui)(gui)的正(zheng)(zheng)壓(ya)(ya)輸(shu)(shu)(shu)(shu)(shu)送(song)(song)系(xi)統(tong)(tong)(tong)(tong)(tong)是懸(xuan)浮輸(shu)(shu)(shu)(shu)(shu)送(song)(song)機(ji)理(li)，物(wu)(wu)料(liao)(liao)以(yi)懸(xuan)浮速(su)(su)度(du)(du)(du)(du)于(yu)壓(ya)(ya)縮(suo)空氣(qi)中運(yun)動(dong)(dong)(dong)，因(yin)此(ci)其(qi)運(yun)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)接近氣(qi)體運(yun)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)；而輸(shu)(shu)(shu)(shu)(shu)灰雙(shuang)套管(guan)規(gui)(gui)格(ge)系(xi)統(tong)(tong)(tong)(tong)(tong)是靜(jing)壓(ya)(ya)輸(shu)(shu)(shu)(shu)(shu)送(song)(song)機(ji)理(li)，物(wu)(wu)料(liao)(liao)是以(yi)半栓塞狀運(yun)動(dong)(dong)(dong)，且上部又有內(nei)旁通管(guan)分(fen)流(liu)氣(qi)流(liu)，因(yin)此(ci)物(wu)(wu)料(liao)(liao)的運(yun)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)大大低(di)(di)于(yu)氣(qi)體運(yun)動(dong)(dong)(dong)速(su)(su)度(du)(du)(du)(du)，與常(chang)規(gui)(gui)正(zheng)(zheng)壓(ya)(ya)輸(shu)(shu)(shu)(shu)(shu)送(song)(song)系(xi)統(tong)(tong)(tong)(tong)(tong)相比，即使是同樣的系(xi)統(tong)(tong)(tong)(tong)(tong)計算流(liu)速(su)(su)，其(qi)物(wu)(wu)料(liao)(liao)的流(liu)速(su)(su)也遠低(di)(di)于(yu)常(chang)規(gui)(gui)正(zheng)(zheng)壓(ya)(ya)輸(shu)(shu)(shu)(shu)(shu)送(song)(song)系(xi)統(tong)(tong)(tong)(tong)(tong)。

眾所周(zhou)知，物料(liao)對(dui)其(qi)他物體的(de)(de)(de)磨(mo)損(sun)速度與該物料(liao)的(de)(de)(de)運(yun)動(dong)速度的(de)(de)(de)三次方成正比，輸(shu)灰雙套(tao)管(guan)規格濃(nong)相(xiang)輸(shu)送(song)(song)系統同(tong)常規系統相(xiang)比，物料(liao)的(de)(de)(de)輸(shu)送(song)(song)真正運(yun)行在低速狀態下，因此對(dui)管(guan)道和彎頭(tou)的(de)(de)(de)磨(mo)損(sun)可以降到很低。由于較低的(de)(de)(de)物料(liao)流(liu)動(dong)速度，極大的(de)(de)(de)降低了物料(liao)對(dui)管(guan)道及管(guan)件的(de)(de)(de)磨(mo)損(sun)，因此，可選用普通鋼管(guan)作輸(shu)送(song)(song)管(guan)道。

控制輸送用氣量：

輸(shu)灰雙套管(guan)規(gui)格(ge)系(xi)統在供氣(qi)(qi)管(guan)上設(she)(she)有(you)調(diao)壓和節(jie)流裝置，以保(bao)證輸(shu)送(song)系(xi)統在設(she)(she)計(ji)要求的工(gong)況下運(yun)(yun)(yun)(yun)行(xing)(xing)，從而(er)保(bao)證輸(shu)送(song)系(xi)統各單(dan)元同時(shi)運(yun)(yun)(yun)(yun)行(xing)(xing)時(shi)用氣(qi)(qi)量穩定。一方(fang)面可改善供氣(qi)(qi)系(xi)統和設(she)(she)備的運(yun)(yun)(yun)(yun)行(xing)(xing)工(gong)況，同時(shi)也防止各單(dan)元在運(yun)(yun)(yun)(yun)行(xing)(xing)過程中因工(gong)況不同互(hu)相(xiang)“搶”氣(qi)(qi)而(er)引(yin)起(qi)堵管(guan)。

自動調節輸送工況：

在每根輸(shu)灰(hui)(hui)雙套管規(gui)格的(de)始端配置(zhi)有混灰(hui)(hui)器（即(ji)輸(shu)灰(hui)(hui)濃度(du)(du)自動調(diao)節裝置(zhi)），當(dang)系(xi)(xi)統(tong)異常輸(shu)灰(hui)(hui)濃度(du)(du)過高，輸(shu)送壓力升高至設計預定(ding)值時，混灰(hui)(hui)系(xi)(xi)統(tong)自動開啟氣旁路，增加輸(shu)送氣量，調(diao)節灰(hui)(hui)氣至適當(dang)的(de)濃度(du)(du)比，提高輸(shu)送能力，將“堵管”消滅在萌芽狀態。

1.輸灰雙套管規格氣力輸送設(she)備在(zai)操(cao)作使用定(ding)要先檢查(cha)電源是(shi)否(fou)插好(hao)，線路(lu)是(shi)否(fou)安全，如果無誤，在(zai)進行下一步操(cao)作。

2.啟(qi)動庫頂脈沖(chong)除塵器，空氣壓縮機，打開氣力輸送設備上部閘板(ban)閥(fa)，進行下料，待小(xiao)料倉有一定物料后，啟(qi)動羅茨(ci)風機。

3.開(kai)啟進氣(qi)閥門，空載試機(ji)5-10分鐘，將輸灰雙套管規格(ge)中的(de)雜物及(ji)焊接時(shi)的(de)熔(rong)渣吹凈。檢查(cha)輸送管路各連接部(bu)位(wei)是否漏(lou)氣(qi)，除塵(chen)器工作是否正常，壓力(li)表是否能正常顯示，如果一切顯示正常，方可繼(ji)續操作。

4.檢查庫頂(ding)除(chu)塵器(qi)應(ying)工(gong)作(zuo)正常，運行阻力(li)＜1500Pa。檢查透氣層是(shi)否損(sun)壞(huai)。安(an)裝時應(ying)特別注意熔渣(zha)燒壞(huai)泵(beng)體底部透氣層。

5.后(hou)結束運(yun)行(xing)時，一定要(yao)檢查電源(yuan)是否切(qie)斷，把執行(xing)機構關閉至零(ling)位將管道送空(kong)后(hou)關停(ting)風機。

當(dang)發(fa)送(song)(song)器(qi)內壓(ya)(ya)力(li)到達必(bi)定(ding)(ding)值時(shi)，壓(ya)(ya)力(li)傳感器(qi)宣布(bu)(bu)信號，出料(liao)閥(fa)主動敞開，流化(hua)床(chuang)上(shang)的物料(liao)流化(hua)加強，輸送(song)(song)開始(shi)，發(fa)送(song)(song)器(qi)物料(liao)逐步削減(jian)，此進(jin)(jin)程(cheng)中流化(hua)床(chuang)上(shang)的物料(liao)，一直處于邊流化(hua)邊輸送(song)(song)。當(dang)發(fa)送(song)(song)器(qi)物料(liao)輸送(song)(song)結(jie)束，輸灰雙套管(guan)(guan)規格(ge)，壓(ya)(ya)力(li)下降到管(guan)(guan)道(dao)阻力(li)時(shi)，指示燈宣布(bu)(bu)信號，通氣連續必(bi)定(ding)(ding)時(shi)刻(ke)，壓(ya)(ya)縮(suo)空氣打掃管(guan)(guan)路，然(ran)后進(jin)(jin)氣閥(fa)封(feng)閉，間(jian)隔必(bi)定(ding)(ding)時(shi)刻(ke)，封(feng)閉出料(liao)閥(fa)，翻開進(jin)(jin)料(liao)閥(fa)。

以上就(jiu)是輸灰(hui)(hui)雙(shuang)套管規格除灰(hui)(hui)系統的(de)基本操作。
