一、電解鋁耗電量如何
電解鋁(lv)行業屬于高(gao)耗能(neng)企業,生(sheng)產(chan)一(yi)噸(dun)電解鋁(lv)綜合電耗13500度電,電解鋁(lv)對于電量需求十分(fen)高(gao),因為電解鋁(lv)的過程是(shi)冰晶(jing)石和氧化鋁(lv)在900多(duo)度的高(gao)溫中進行電解。
以2020年為例:2020年中國電解鋁產量為3731.7萬噸,占全(quan)世(shi)界的57.18%,僅電解(jie)鋁(lv)一項耗電總(zong)量就達到約4851.21億千瓦時。而(er)2020年(nian)中國(guo)全(quan)社會用(yong)電量也只有75110億千瓦時,只是電解(jie)鋁(lv)就約占全(quan)國(guo)用(yong)電量的6.46%。
二、電解鋁耗電量怎么算
電(dian)解鋁的(de)(de)耗電(dian)量是根(gen)據電(dian)流(liu)、時(shi)間(jian)、電(dian)壓(ya)和(he)電(dian)解質濃度來計算的(de)(de),具體方法如下:
1、確定電流大小
鋁制品供應總量、電(dian)(dian)解(jie)(jie)鋁的用途、原(yuan)材料成本、發電(dian)(dian)機功率(lv)因(yin)數等眾多因(yin)素(su)決定了電(dian)(dian)解(jie)(jie)鋁過程(cheng)中的電(dian)(dian)流大(da)小。電(dian)(dian)流的單位為安培,電(dian)(dian)流越大(da),耗電(dian)(dian)量就(jiu)越大(da)。
2、確定電解質濃度
電(dian)(dian)(dian)解(jie)(jie)質(zhi)指(zhi)在電(dian)(dian)(dian)解(jie)(jie)過程(cheng)中起著導電(dian)(dian)(dian)和(he)溶解(jie)(jie)氧化鋁的作用的化學物質(zhi)。電(dian)(dian)(dian)解(jie)(jie)質(zhi)的濃度(du)會影響(xiang)電(dian)(dian)(dian)解(jie)(jie)過程(cheng)的速率和(he)耗電(dian)(dian)(dian)量。一般來說,濃度(du)越(yue)(yue)大,電(dian)(dian)(dian)源電(dian)(dian)(dian)壓就(jiu)越(yue)(yue)高(gao),而電(dian)(dian)(dian)流就(jiu)越(yue)(yue)小,反之亦然(ran)。
3、確定電壓大小
電(dian)(dian)壓(ya)指電(dian)(dian)解(jie)過程(cheng)(cheng)(cheng)中(zhong)使(shi)用(yong)的電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)。電(dian)(dian)解(jie)鋁(lv)過程(cheng)(cheng)(cheng)中(zhong)的電(dian)(dian)壓(ya)大(da)小會影(ying)響電(dian)(dian)流的大(da)小和(he)耗電(dian)(dian)量。電(dian)(dian)解(jie)鋁(lv)過程(cheng)(cheng)(cheng)中(zhong)所用(yong)的電(dian)(dian)源(yuan)的電(dian)(dian)壓(ya)通常與電(dian)(dian)解(jie)質的濃度和(he)電(dian)(dian)流的大(da)小有關(guan)。
4、計算時間
時間(jian)是指電(dian)解鋁過(guo)(guo)程中電(dian)流通過(guo)(guo)的時間(jian)。時間(jian)的單位通常為秒、分(fen)鐘或小時。
5、計算電解鋁的耗電量
電解鋁(lv)耗電量(liang)的計算公式為:電解鋁(lv)的耗電量(liang)(度)=電功(千(qian)瓦時)x時間(jian)(小時)=電流(liu)(安培)x電壓(伏特(te))x時間(jian)(小時)/1000。
