一、電解鋁耗電量如何

電(dian)(dian)解(jie)(jie)鋁(lv)(lv)行業(ye)屬于高(gao)耗能企(qi)業(ye)，生產一噸電(dian)(dian)解(jie)(jie)鋁(lv)(lv)綜合(he)電(dian)(dian)耗13500度(du)電(dian)(dian)，電(dian)(dian)解(jie)(jie)鋁(lv)(lv)對于電(dian)(dian)量需求(qiu)十分高(gao)，因為電(dian)(dian)解(jie)(jie)鋁(lv)(lv)的過程(cheng)是冰晶(jing)石和氧化鋁(lv)(lv)在900多度(du)的高(gao)溫中進行電(dian)(dian)解(jie)(jie)。

以2020年為例：2020年中國電解鋁產量為3731.7萬(wan)噸，占(zhan)全世界的57.18%，僅電(dian)(dian)解(jie)鋁一項(xiang)耗電(dian)(dian)總量就達(da)到約4851.21億千(qian)瓦(wa)時。而2020年中(zhong)國(guo)全社會用電(dian)(dian)量也只(zhi)有(you)75110億千(qian)瓦(wa)時，只(zhi)是電(dian)(dian)解(jie)鋁就約占(zhan)全國(guo)用電(dian)(dian)量的6.46%。

二、電解鋁耗電量怎么算

電(dian)解鋁(lv)的(de)耗(hao)電(dian)量(liang)是根據電(dian)流、時間、電(dian)壓和(he)電(dian)解質(zhi)濃度來計(ji)算的(de)，具體方法如(ru)下：

1、確定電流大小

鋁(lv)(lv)制品供(gong)應總量、電解鋁(lv)(lv)的(de)用途、原材料成本、發(fa)電機(ji)功(gong)率(lv)因數等(deng)眾(zhong)多因素決定了電解鋁(lv)(lv)過(guo)程中的(de)電流(liu)大(da)小。電流(liu)的(de)單位為安培，電流(liu)越大(da)，耗電量就越大(da)。

2、確定電解質濃度

電(dian)(dian)解(jie)(jie)(jie)質(zhi)指在電(dian)(dian)解(jie)(jie)(jie)過程(cheng)中起(qi)著導電(dian)(dian)和溶(rong)解(jie)(jie)(jie)氧(yang)化鋁的作用的化學物質(zhi)。電(dian)(dian)解(jie)(jie)(jie)質(zhi)的濃(nong)度會影響電(dian)(dian)解(jie)(jie)(jie)過程(cheng)的速率和耗電(dian)(dian)量。一般來說，濃(nong)度越(yue)(yue)大，電(dian)(dian)源電(dian)(dian)壓就越(yue)(yue)高(gao)，而電(dian)(dian)流(liu)就越(yue)(yue)小，反之亦然。

3、確定電壓大小

電(dian)(dian)(dian)壓指(zhi)電(dian)(dian)(dian)解過(guo)(guo)程中使用(yong)的(de)(de)(de)電(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)壓。電(dian)(dian)(dian)解鋁過(guo)(guo)程中的(de)(de)(de)電(dian)(dian)(dian)壓大(da)(da)小會影(ying)響電(dian)(dian)(dian)流的(de)(de)(de)大(da)(da)小和(he)耗電(dian)(dian)(dian)量(liang)。電(dian)(dian)(dian)解鋁過(guo)(guo)程中所用(yong)的(de)(de)(de)電(dian)(dian)(dian)源(yuan)的(de)(de)(de)電(dian)(dian)(dian)壓通常(chang)與電(dian)(dian)(dian)解質的(de)(de)(de)濃度和(he)電(dian)(dian)(dian)流的(de)(de)(de)大(da)(da)小有(you)關。

4、計算時間

時(shi)(shi)間(jian)是指電解鋁過(guo)程中(zhong)電流通(tong)過(guo)的(de)時(shi)(shi)間(jian)。時(shi)(shi)間(jian)的(de)單(dan)位(wei)通(tong)常為(wei)秒、分鐘或(huo)小時(shi)(shi)。

5、計算電解鋁的耗電量

電(dian)(dian)解鋁耗(hao)電(dian)(dian)量(liang)(liang)的計(ji)算公式為：電(dian)(dian)解鋁的耗(hao)電(dian)(dian)量(liang)(liang)（度(du)）=電(dian)(dian)功(gong)（千瓦時(shi)(shi)）x時(shi)(shi)間（小時(shi)(shi)）=電(dian)(dian)流（安培）x電(dian)(dian)壓（伏特）x時(shi)(shi)間（小時(shi)(shi)）/1000。
