一、電解鋁耗電量如何
電(dian)解鋁行(xing)業屬于(yu)高耗能企(qi)業,生產一(yi)噸電(dian)解鋁綜合電(dian)耗13500度電(dian),電(dian)解鋁對于(yu)電(dian)量(liang)需(xu)求十分高,因為電(dian)解鋁的過程是冰晶石和氧化鋁在900多(duo)度的高溫(wen)中進行(xing)電(dian)解。
以2020年為例:2020年中國電解鋁產量(liang)為3731.7萬(wan)噸,占全世界的(de)57.18%,僅電(dian)解(jie)鋁(lv)一項耗電(dian)總量(liang)就(jiu)達到約4851.21億(yi)千瓦(wa)時。而2020年中國全社會用(yong)電(dian)量(liang)也(ye)只有75110億(yi)千瓦(wa)時,只是電(dian)解(jie)鋁(lv)就(jiu)約占全國用(yong)電(dian)量(liang)的(de)6.46%。
二、電解鋁耗電量怎么算
電(dian)解鋁的耗電(dian)量(liang)是根據電(dian)流、時(shi)間、電(dian)壓(ya)和電(dian)解質(zhi)濃度來計算(suan)的,具(ju)體方(fang)法如下:
1、確定電流大小
鋁制品供應總量、電(dian)(dian)(dian)解鋁的用途(tu)、原材(cai)料(liao)成本、發(fa)電(dian)(dian)(dian)機功率因(yin)數等眾多因(yin)素決定了電(dian)(dian)(dian)解鋁過程中的電(dian)(dian)(dian)流(liu)大(da)(da)小。電(dian)(dian)(dian)流(liu)的單位為安培,電(dian)(dian)(dian)流(liu)越(yue)大(da)(da),耗(hao)電(dian)(dian)(dian)量就越(yue)大(da)(da)。
2、確定電解質濃度
電(dian)(dian)解質(zhi)指(zhi)在電(dian)(dian)解過程中(zhong)起著(zhu)導電(dian)(dian)和(he)溶(rong)解氧化(hua)鋁(lv)的作用的化(hua)學物質(zhi)。電(dian)(dian)解質(zhi)的濃度(du)會影(ying)響電(dian)(dian)解過程的速率和(he)耗電(dian)(dian)量。一般(ban)來說,濃度(du)越大,電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)就越高,而電(dian)(dian)流就越小,反(fan)之亦然。
3、確定電壓大小
電(dian)壓指電(dian)解(jie)過(guo)程(cheng)中(zhong)(zhong)使用(yong)的(de)(de)電(dian)源電(dian)壓。電(dian)解(jie)鋁過(guo)程(cheng)中(zhong)(zhong)的(de)(de)電(dian)壓大小(xiao)會影(ying)響電(dian)流的(de)(de)大小(xiao)和耗電(dian)量。電(dian)解(jie)鋁過(guo)程(cheng)中(zhong)(zhong)所用(yong)的(de)(de)電(dian)源的(de)(de)電(dian)壓通常(chang)與電(dian)解(jie)質(zhi)的(de)(de)濃度和電(dian)流的(de)(de)大小(xiao)有關(guan)。
4、計算時間
時(shi)間是指電解鋁過(guo)程中電流通過(guo)的時(shi)間。時(shi)間的單(dan)位通常為秒、分(fen)鐘或小時(shi)。
5、計算電解鋁的耗電量
電(dian)解鋁(lv)耗電(dian)量(liang)的計算公式(shi)為(wei):電(dian)解鋁(lv)的耗電(dian)量(liang)(度)=電(dian)功(千瓦(wa)時)x時間(jian)(小(xiao)時)=電(dian)流(安(an)培(pei))x電(dian)壓(伏特)x時間(jian)(小(xiao)時)/1000。
