一、電解鋁耗電量如何

電(dian)(dian)(dian)(dian)解(jie)鋁行業屬于高(gao)耗能企業，生(sheng)產一(yi)噸(dun)電(dian)(dian)(dian)(dian)解(jie)鋁綜合(he)電(dian)(dian)(dian)(dian)耗13500度電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)解(jie)鋁對于電(dian)(dian)(dian)(dian)量需求十(shi)分高(gao)，因為電(dian)(dian)(dian)(dian)解(jie)鋁的(de)過程是(shi)冰(bing)晶石和(he)氧化鋁在900多度的(de)高(gao)溫中進行電(dian)(dian)(dian)(dian)解(jie)。

以2020年為例：2020年中國電解鋁產量(liang)(liang)為3731.7萬(wan)噸，占(zhan)全世界的57.18%，僅電(dian)(dian)解鋁一(yi)項耗(hao)電(dian)(dian)總量(liang)(liang)就(jiu)達到約4851.21億千(qian)瓦(wa)時。而2020年中(zhong)國全社(she)會用電(dian)(dian)量(liang)(liang)也只(zhi)有(you)75110億千(qian)瓦(wa)時，只(zhi)是電(dian)(dian)解鋁就(jiu)約占(zhan)全國用電(dian)(dian)量(liang)(liang)的6.46%。

二、電解鋁耗電量怎么算

電(dian)解(jie)鋁(lv)的耗電(dian)量是根據電(dian)流、時間(jian)、電(dian)壓(ya)和電(dian)解(jie)質濃(nong)度來計算的，具體方法如下：

1、確定電流大小

鋁制品供應總量、電(dian)(dian)(dian)解鋁的用途、原材料(liao)成本、發電(dian)(dian)(dian)機功率因數(shu)等眾多因素(su)決(jue)定了電(dian)(dian)(dian)解鋁過程中(zhong)的電(dian)(dian)(dian)流大(da)小。電(dian)(dian)(dian)流的單(dan)位為安培，電(dian)(dian)(dian)流越大(da)，耗(hao)電(dian)(dian)(dian)量就越大(da)。

2、確定電解質濃度

電(dian)解(jie)質(zhi)指在電(dian)解(jie)過(guo)程中起著導電(dian)和溶解(jie)氧化鋁的(de)(de)作用的(de)(de)化學物質(zhi)。電(dian)解(jie)質(zhi)的(de)(de)濃度(du)會影響電(dian)解(jie)過(guo)程的(de)(de)速率和耗電(dian)量。一般(ban)來說(shuo)，濃度(du)越大，電(dian)源電(dian)壓就越高，而電(dian)流(liu)就越小，反之亦(yi)然。

3、確定電壓大小

電(dian)(dian)壓(ya)指電(dian)(dian)解過程(cheng)中使用(yong)的(de)電(dian)(dian)源電(dian)(dian)壓(ya)。電(dian)(dian)解鋁(lv)過程(cheng)中的(de)電(dian)(dian)壓(ya)大(da)小(xiao)會影響電(dian)(dian)流的(de)大(da)小(xiao)和耗電(dian)(dian)量。電(dian)(dian)解鋁(lv)過程(cheng)中所用(yong)的(de)電(dian)(dian)源的(de)電(dian)(dian)壓(ya)通常與電(dian)(dian)解質的(de)濃(nong)度和電(dian)(dian)流的(de)大(da)小(xiao)有(you)關(guan)。

4、計算時間

時(shi)間(jian)是指電解鋁過(guo)程中電流通過(guo)的時(shi)間(jian)。時(shi)間(jian)的單位通常為(wei)秒、分鐘或小時(shi)。

5、計算電解鋁的耗電量

電(dian)解鋁(lv)耗電(dian)量的計(ji)算公式為：電(dian)解鋁(lv)的耗電(dian)量（度）=電(dian)功(gong)（千瓦時(shi)）x時(shi)間（小時(shi)）=電(dian)流（安培(pei)）x電(dian)壓（伏特）x時(shi)間（小時(shi)）/1000。
