一、電解鋁耗電量如何

電(dian)(dian)解鋁行業屬于高(gao)耗能企業，生產一噸電(dian)(dian)解鋁綜合電(dian)(dian)耗13500度電(dian)(dian)，電(dian)(dian)解鋁對于電(dian)(dian)量需求十分高(gao)，因為電(dian)(dian)解鋁的(de)過程是冰晶(jing)石和(he)氧(yang)化鋁在(zai)900多度的(de)高(gao)溫中進行電(dian)(dian)解。

以2020年為例：2020年中國電解鋁產量為(wei)3731.7萬噸，占(zhan)全世界的57.18%，僅(jin)電(dian)解(jie)鋁一項耗電(dian)總(zong)量就(jiu)達(da)到約4851.21億千瓦時(shi)。而2020年中國(guo)全社會用電(dian)量也(ye)只(zhi)有(you)75110億千瓦時(shi)，只(zhi)是電(dian)解(jie)鋁就(jiu)約占(zhan)全國(guo)用電(dian)量的6.46%。

二、電解鋁耗電量怎么算

電(dian)(dian)解鋁的(de)耗電(dian)(dian)量是(shi)根據電(dian)(dian)流(liu)、時間、電(dian)(dian)壓(ya)和(he)電(dian)(dian)解質濃度來計算(suan)的(de)，具體方法如下：

1、確定電流大小

鋁(lv)制品供應總(zong)量(liang)、電(dian)解(jie)(jie)鋁(lv)的(de)用途、原材料(liao)成本、發電(dian)機功率(lv)因數等眾多因素(su)決定(ding)了(le)電(dian)解(jie)(jie)鋁(lv)過(guo)程中(zhong)的(de)電(dian)流(liu)(liu)大(da)小。電(dian)流(liu)(liu)的(de)單位為安培(pei)，電(dian)流(liu)(liu)越(yue)大(da)，耗電(dian)量(liang)就越(yue)大(da)。

2、確定電解質濃度

電(dian)解(jie)質指在電(dian)解(jie)過程中起著導電(dian)和溶解(jie)氧化(hua)鋁(lv)的作用的化(hua)學物質。電(dian)解(jie)質的濃度(du)會影(ying)響電(dian)解(jie)過程的速率和耗(hao)電(dian)量。一般來(lai)說，濃度(du)越(yue)大，電(dian)源電(dian)壓(ya)就越(yue)高，而電(dian)流(liu)就越(yue)小，反(fan)之亦然。

3、確定電壓大小

電(dian)(dian)(dian)壓指電(dian)(dian)(dian)解過(guo)程中使用的電(dian)(dian)(dian)源電(dian)(dian)(dian)壓。電(dian)(dian)(dian)解鋁(lv)過(guo)程中的電(dian)(dian)(dian)壓大小會影響(xiang)電(dian)(dian)(dian)流(liu)的大小和耗(hao)電(dian)(dian)(dian)量(liang)。電(dian)(dian)(dian)解鋁(lv)過(guo)程中所用的電(dian)(dian)(dian)源的電(dian)(dian)(dian)壓通(tong)常與電(dian)(dian)(dian)解質的濃度和電(dian)(dian)(dian)流(liu)的大小有(you)關(guan)。

4、計算時間

時(shi)間是(shi)指(zhi)電解鋁過(guo)程中電流通(tong)過(guo)的(de)時(shi)間。時(shi)間的(de)單位通(tong)常為(wei)秒(miao)、分鐘或小時(shi)。

5、計算電解鋁的耗電量

電(dian)(dian)解鋁(lv)耗(hao)電(dian)(dian)量的計算公式為：電(dian)(dian)解鋁(lv)的耗(hao)電(dian)(dian)量（度）=電(dian)(dian)功(gong)（千瓦時）x時間（小(xiao)時）=電(dian)(dian)流（安培）x電(dian)(dian)壓（伏特）x時間（小(xiao)時）/1000。
