一、電解鋁耗電量如何

電(dian)(dian)(dian)解(jie)鋁(lv)行(xing)業屬于高耗能(neng)企業，生產一噸(dun)電(dian)(dian)(dian)解(jie)鋁(lv)綜(zong)合電(dian)(dian)(dian)耗13500度電(dian)(dian)(dian)，電(dian)(dian)(dian)解(jie)鋁(lv)對(dui)于電(dian)(dian)(dian)量需求十分高，因為電(dian)(dian)(dian)解(jie)鋁(lv)的(de)過程是冰(bing)晶石和氧化鋁(lv)在900多度的(de)高溫中進行(xing)電(dian)(dian)(dian)解(jie)。

以2020年為例：2020年中國電解鋁產量為3731.7萬(wan)噸，占全(quan)世(shi)界(jie)的(de)57.18%，僅電解鋁一(yi)項耗電總量就達到約4851.21億(yi)千瓦(wa)時。而2020年(nian)中國(guo)全(quan)社會用電量也只有75110億(yi)千瓦(wa)時，只是(shi)電解鋁就約占全(quan)國(guo)用電量的(de)6.46%。

二、電解鋁耗電量怎么算

電解(jie)鋁的耗(hao)電量是根據電流、時(shi)間、電壓和電解(jie)質濃(nong)度來計算的，具體(ti)方法如(ru)下：

1、確定電流大小

鋁(lv)制品供應總量(liang)、電(dian)(dian)解鋁(lv)的(de)(de)用途(tu)、原材料成本、發(fa)電(dian)(dian)機功率因數等眾(zhong)多因素決定了電(dian)(dian)解鋁(lv)過(guo)程(cheng)中的(de)(de)電(dian)(dian)流(liu)(liu)大小。電(dian)(dian)流(liu)(liu)的(de)(de)單(dan)位為安培，電(dian)(dian)流(liu)(liu)越(yue)大，耗電(dian)(dian)量(liang)就越(yue)大。

2、確定電解質濃度

電(dian)解質(zhi)(zhi)指在電(dian)解過程中起(qi)著(zhu)導電(dian)和溶(rong)解氧化鋁(lv)的(de)作用的(de)化學物(wu)質(zhi)(zhi)。電(dian)解質(zhi)(zhi)的(de)濃(nong)度會(hui)影響電(dian)解過程的(de)速率和耗電(dian)量。一般來說，濃(nong)度越大，電(dian)源電(dian)壓就越高，而(er)電(dian)流就越小，反(fan)之亦(yi)然(ran)。

3、確定電壓大小

電(dian)(dian)(dian)(dian)壓(ya)指電(dian)(dian)(dian)(dian)解過程(cheng)中使用(yong)的(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)。電(dian)(dian)(dian)(dian)解鋁(lv)過程(cheng)中的(de)電(dian)(dian)(dian)(dian)壓(ya)大小會影響(xiang)電(dian)(dian)(dian)(dian)流(liu)的(de)大小和(he)耗電(dian)(dian)(dian)(dian)量。電(dian)(dian)(dian)(dian)解鋁(lv)過程(cheng)中所用(yong)的(de)電(dian)(dian)(dian)(dian)源的(de)電(dian)(dian)(dian)(dian)壓(ya)通常與電(dian)(dian)(dian)(dian)解質的(de)濃度和(he)電(dian)(dian)(dian)(dian)流(liu)的(de)大小有(you)關。

4、計算時間

時(shi)間(jian)是(shi)指電(dian)解鋁過程中電(dian)流(liu)通過的(de)時(shi)間(jian)。時(shi)間(jian)的(de)單(dan)位通常為秒、分鐘或小時(shi)。

5、計算電解鋁的耗電量

電(dian)解鋁耗(hao)電(dian)量的(de)計算(suan)公式(shi)為：電(dian)解鋁的(de)耗(hao)電(dian)量（度）=電(dian)功（千(qian)瓦(wa)時）x時間（小時）=電(dian)流（安培）x電(dian)壓(ya)（伏特(te)）x時間（小時）/1000。
