目前，粉體氣力輸送機料封泵在火(huo)電廠除灰設(she)計技術中應用Z為廣泛。

    火電廠除(chu)灰(hui)設計技術是目(mu)前料(liao)(liao)封(feng)(feng)泵(beng)應(ying)用中(zhong)(zhong)應(ying)用Z廣泛的(de)(de)(de)粉體輸(shu)(shu)(shu)送(song)形式。它(ta)根據輸(shu)(shu)(shu)送(song)壓(ya)(ya)力的(de)(de)(de)不同(tong)，將氣(qi)(qi)(qi)(qi)力清(qing)灰(hui)方式分(fen)為(wei)(wei)正(zheng)壓(ya)(ya)系(xi)統(tong)和負(fu)壓(ya)(ya)系(xi)統(tong)兩大(da)類(lei)。通(tong)過(guo)現(xian)(xian)場(chang)合理布置料(liao)(liao)封(feng)(feng)泵(beng)管道(dao)，可(ke)以實現(xian)(xian)良*效(xiao)率的(de)(de)(de)粉體輸(shu)(shu)(shu)送(song)。現(xian)(xian)場(chang)施工(gong)(gong)時，料(liao)(liao)封(feng)(feng)泵(beng)具有使物料(liao)(liao)進(jin)入流化狀態的(de)(de)(de)作用，使粉狀物料(liao)(liao)能(neng)夠在管道(dao)中(zhong)(zhong)輸(shu)(shu)(shu)送(song)。長距離輸(shu)(shu)(shu)送(song)，料(liao)(liao)封(feng)(feng)泵(beng)正(zheng)壓(ya)(ya)輸(shu)(shu)(shu)送(song)系(xi)統(tong)、鎖(suo)氣(qi)(qi)(qi)(qi)閥正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)動(dong)(dong)清(qing)灰(hui)系(xi)統(tong)、料(liao)(liao)封(feng)(feng)泵(beng)正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)動(dong)(dong)清(qing)灰(hui)系(xi)統(tong)、雙套管紊流正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)動(dong)(dong)清(qing)灰(hui)系(xi)統(tong)、脈(mo)沖氣(qi)(qi)(qi)(qi)動(dong)(dong)栓塞正(zheng)壓(ya)(ya)氣(qi)(qi)(qi)(qi)動(dong)(dong)除(chu)灰(hui)系(xi)統(tong)統(tong)稱為(wei)(wei)正(zheng)壓(ya)(ya)系(xi)統(tong)。利用抽氣(qi)(qi)(qi)(qi)設備的(de)(de)(de)抽吸作用，使除(chu)灰(hui)系(xi)統(tong)內(nei)產生一定的(de)(de)(de)負(fu)壓(ya)(ya)，使灰(hui)燼與空(kong)氣(qi)(qi)(qi)(qi)混(hun)合，一起(qi)被吸入管道(dao)。這種運輸(shu)(shu)(shu)方式屬于負(fu)壓(ya)(ya)系(xi)統(tong)。針(zhen)對不同(tong)的(de)(de)(de)交通(tong)系(xi)統(tong)，需要(yao)進(jin)行適當(dang)的(de)(de)(de)選擇。氣(qi)(qi)(qi)(qi)動(dong)(dong)方式輸(shu)(shu)(shu)送(song)粉體，通(tong)過(guo)料(liao)(liao)封(feng)(feng)泵(beng)的(de)(de)(de)合理構造(zao)，可(ke)以有效(xiao)降低料(liao)(liao)封(feng)(feng)泵(beng)的(de)(de)(de)能(neng)耗，從(cong)而達到工(gong)(gong)業環保所(suo)需的(de)(de)(de)節能(neng)減排效(xiao)果。
