臭氧發生器用于水處理消毒系統設計注意事項
臭(chou)氧(yang)發(fa)生(sheng)器應用(yong)于水(shui)處理工程等場合時,有很多因(yin)素可(ke)能影響發(fa)生(sheng)器的(de)效率及(ji)其(qi)可(ke)靠性(xing),因(yin)此在(zai)設(she)計臭(chou)氧(yang)發(fa)生(sheng)器應用(yong)系(xi)統(tong)時必須注意的(de)事項你知(zhi)道有哪些嗎?
1、發生器原料氣體不得含烴類、腐蝕性氣體和任何其他能在氧/臭氧/電暈環境內發生反應,從而對設備安全造成危害或損壞的物質。從所周知,爆炸的三要素是 燃料、氧化劑和火種,而臭氧發生器的電暈環境中已存在兩項,即氧化劑和火種。因此必須防止在原料氣體中含有烴類燃料物質;如果有可能存在烴類物質,必須安 裝烴類分析儀,以便當烴類濃度接近爆炸下限(LEl)的25%時切斷電源碳氟化合物,如特氟隆或冷卻劑都可在電暈中分解形成氟,后者能侵蝕玻璃介電材料,可加速介電體損壞。圍繞在電暈室外面的循環冷卻流體有可能通過密封泄漏 并進入電暈空間,結果在介電體表面形成一層漆類,涂層。當發生這種情況時,由于這種涂層降低臭氧生產的效率,介電體必須定期予以清洗。另外,原料氣還應濾 除5μm左右的顆粒,以防止小的干燥劑粉末或其他微粒進入發生器電暈區。以免影響電暈效率。
2、供氣(qi)壓力不能無控制地改變,由于(yu)氣(qi)壓影響電(dian)(dian)暈功率誘導和跨越介電(dian)(dian)體(ti)所加(jia)電(dian)(dian)壓,大(da)范圍壓力變化會使(shi)發生器(qi)運(yun)行不可靠。超出電(dian)(dian)暈功率范圍可造(zao)成熔(rong)斷(duan)器(qi)或(huo)自(zi)動斷(duan)電(dian)(dian)器(qi)斷(duan)開。超出外加(jia)電(dian)(dian)壓峰值(zhi)還能造(zao)成介電(dian)(dian)體(ti)過(guo)早失(shi)效。
3、臭(chou)(chou)氧(yang)發生(sheng)(sheng)(sheng)器(qi)(qi)系統設計(ji)(ji)時,必須(xu)(xu)能防止(zhi)大(da)量(liang)水進入到發生(sheng)(sheng)(sheng)器(qi)(qi)內(nei)。水封供氣(qi)(qi)壓縮機用的(de)浮閥(fa)或空氣(qi)(qi)干燥器(qi)(qi)上的(de)凝結(jie)水閥(fa)阻(zu)(zu)塞卡(ka)住,都會(hui)造成(cheng)發生(sheng)(sheng)(sheng)器(qi)(qi)電(dian)(dian)暈室(shi)內(nei)灌(guan)水。電(dian)(dian)暈室(shi) 內(nei)大(da)量(liang)進水可導致電(dian)(dian)暈集中、高電(dian)(dian)流密度和(he)局部電(dian)(dian)介(jie)體(ti)發熱,造成(cheng)介(jie)電(dian)(dian)體(ti)過早失效。即使檢測裝置(zhi)在(zai)水進入電(dian)(dian)暈室(shi)之前切(qie)斷電(dian)(dian)暈電(dian)(dian)源,水中所含雜(za)質(zhi)也會(hui)沉積(ji)在(zai)元件 表面上,這些雜(za)質(zhi)必須(xu)(xu)在(zai)繼續運(yun)行(xing)之前予(yu)以清除。運(yun)行(xing)故障(zhang)或操(cao)作錯誤都能迫使處理(li)出水從(cong)臭(chou)(chou)氧(yang)接觸池(chi)到流發生(sheng)(sheng)(sheng)器(qi)(qi)內(nei),少會(hui)造成(cheng)電(dian)(dian)暈元件污染(ran)或者介(jie)電(dian)(dian)體(ti)損壞(huai)。此外,系統設計(ji)(ji)和(he)操(cao)作規程(cheng)必須(xu)(xu)阻(zu)(zu)止(zhi)易燃的(de)腐蝕性氣(qi)(qi)體(ti)及從(cong)臭(chou)(chou)氧(yang)接觸池(chi)回流的(de)水蒸(zheng)氣(qi)(qi)進入發生(sheng)(sheng)(sheng)器(qi)(qi)內(nei)。
