水覆蓋了地球2/3的表面，水構(gòu)成了人類身體的75%，水是生命之源。但是，我們的地球上還有不少地方嚴(yán)重缺乏甚至完全沒有飲用水。ABB水處理行業(yè)解決方案正在幫助改變這一現(xiàn)狀。
電費(fèi)是海水淡化最大開支之一，所以在生產(chǎn)流程實(shí)現(xiàn)增效節(jié)能就意味著讓飲用水變得更加經(jīng)濟(jì)實(shí)惠。?
電費(fèi)是海水淡化過程最大的單項(xiàng)開支之一，所以ABB解決方案的能源效率對該項(xiàng)目至關(guān)重要。提高流程能源效率可以讓飲用水變得更加經(jīng)濟(jì)。
阿爾及利亞全國基本都可以用“干旱貧瘠”來形容，其80%的土地都被沙漠覆蓋，降雨量幾乎為零。然而，可靠且高性價(jià)比的海水淡化工藝和地中海卻能夠?yàn)榘柤袄麃喬峁┏渥愕娘嬘盟?/div>
2011年投入運(yùn)營后，馬格塔（Magtaa）海水淡化廠每天將可以生產(chǎn)50萬立方米飲用水，能夠滿足約500萬人的需求。
完整的電氣解決方案
ABB為整座工廠提供了完整的電氣解決方案，包括電力變壓器、一系列中壓和低壓開關(guān)以及一個(gè)220千伏戶外變電站，以保證淡化流程獲得穩(wěn)定充足的電力供應(yīng)，同時(shí)避免對阿爾及利亞電網(wǎng)的干擾。
ABB還為淡化流程提供了33個(gè)中壓變頻器。與依靠閥門進(jìn)行控制的傳統(tǒng)方法相比，這種智能化電機(jī)控制系統(tǒng)可以顯著減少海水淡化廠驅(qū)動(dòng)水泵及其它設(shè)備的電機(jī)能耗。
在這座海水淡化廠里，變頻器可以把電能損耗從標(biāo)準(zhǔn)的5%降低到3%，相對于目前公認(rèn)的行業(yè)標(biāo)準(zhǔn)，這是個(gè)巨大的進(jìn)步。
ABB中壓變頻器可以根據(jù)實(shí)際需要調(diào)節(jié)電機(jī)轉(zhuǎn)速，優(yōu)化能耗。
這一點(diǎn)十分重要，因?yàn)樵诘鞒汤锩婺芎恼紦?jù)了生產(chǎn)總成本的20%-60%。通過改善能效，降低能耗成本，飲用水價(jià)格更為經(jīng)濟(jì)，可以被更多人所接受。
ABB變頻器還可以減少工廠例行檢修的停機(jī)時(shí)間，減輕水泵承受的
機(jī)械壓力和電機(jī)承受的電壓，并且延長反滲透淡化流程核心設(shè)備——半透膜的壽命。
ABB是水處理行業(yè)領(lǐng)先的電力和自動(dòng)化解決方案供應(yīng)商，可以提供全套集成與優(yōu)化的儀表、控制和電氣系統(tǒng)，以及一系列用于提高生產(chǎn)設(shè)備能源效率、生產(chǎn)率和穩(wěn)定性的自動(dòng)化產(chǎn)品。
戰(zhàn)略合作伙伴
馬格塔海水淡化廠由專注于膜應(yīng)用的亞洲領(lǐng)先水處理公司新加坡凱發(fā)集團(tuán)（Hyflux Ltd.）承建。ABB已經(jīng)與凱發(fā)集團(tuán)簽署戰(zhàn)略合作協(xié)議，共同開發(fā)針對反滲透膜優(yōu)化與監(jiān)控，以及水泵效率管理的增效節(jié)能技術(shù)和解決方案。
