為你的生產操作選擇(ze)恰當的噴(pen)嘴是至(zhi)關重要的!

除此之外，配(pei)套的設施(shi)也是同樣重要(yao)！一般情況(kuang)下(xia)，一根(gen)簡單(dan)的管路(lu)就能(neng)(neng)滿(man)足你(ni)的應用。但在多數的情況(kuang)里，如果能(neng)(neng)選擇恰當的管路(lu)配(pei)套設施(shi)，可(ke)顯(xian)著提高噴嘴性(xing)能(neng)(neng)，減少維護成本！

- 我們將噴(pen)霧知識應用(yong)在每一個歧管、噴(pen)槍和集管上， 所以我們能確保(bao)給噴(pen)嘴提供適當的液體和/或(huo)氣

體流(liu)量， 達(da)到預期的效果。另(ling)外(wai)， 我們確保(bao)了連接與材料的兼容(rong)， 簡化安裝， 并提(ti)供長(chang)久持續的性能。

- 在很多操(cao)作過(guo)程中， 我們協助確(que)定設(she)備的(de)噴嘴布置(zhi)和位置(zhi)， 并確(que)定設(she)備的(de)操(cao)作位置(zhi)。

- 對于關鍵的應(ying)用(yong)， 如煙氣冷卻和化工(gong)加工(gong)， 我們能滿足大多數嚴(yan)格的需求––特殊材料和涂層， 符合B31.1、

B31.3、cGMP及更(geng)多規范要求。

- 所有供料(liao)設備， 我們都是為(wei)簡單(dan)安裝(zhuang)和(he)維護而設計制造的。

脫硝、冷卻噴槍好在哪里？

濰坊北科環保設備(bei)有(you)限公(gong)司生產的(de)煙(yan)氣(qi)冷卻(que)、脫硫(liu)噴槍主要用(yong)在(zai)煙(yan)氣(qi)在(zai)經過除塵器前都必須進行有(you)效的(de)降溫和(he)調(diao)質，噴霧(wu)技術仍(reng)然是(shi)容(rong)易(yi)和(he)有(you)效的(de)方案，主要部分還是(shi)節能(neng)噴嘴

1、霧化顆粒細小、均勻、確保液體(ti)能與氣體(ti)更好的結合而(er)達到完全(quan)蒸(zheng)發。

2、噴(pen)槍噴(pen)霧角(jiao)度大，而(er)使(shi)得霧化(hua)水霧覆蓋面(mian)積比較(jiao)大。氣(qi)液霧化(hua)噴(pen)槍的霧化(hua)直徑可達3um-4um，能(neng)與煙(yan)氣(qi)混(hun)合充分，有(you)利于煙(yan)氣(qi)降溫(wen)調量，而(er)在整(zheng)個水量變化(hua)范圍內(nei)，霧化(hua)顆粒基本(ben)保持不(bu)變。

3、節能，高(gao)霧化的(de)條(tiao)件(jian)下只(zhi)需(xu)要2-3公斤的(de)水、氣壓力。除噴槍使用氣，水都為低(di)壓，能源消耗(hao)低(di)以外，由于氣液霧化噴槍可(ke)在保證不濕底的(de)條(tiao)件(jian)下將煙氣溫度(du)調到設定值。使進(jin)入除塵器的(de)煙氣量相對減(jian)少，風機電耗(hao)相應(ying)降低(di)。
