一、電解鋁耗電量如何

電(dian)解(jie)鋁(lv)行(xing)業屬于高耗(hao)(hao)能企業，生產一噸電(dian)解(jie)鋁(lv)綜合電(dian)耗(hao)(hao)13500度(du)電(dian)，電(dian)解(jie)鋁(lv)對于電(dian)量需求十分高，因為電(dian)解(jie)鋁(lv)的過(guo)程是冰(bing)晶石和氧(yang)化鋁(lv)在900多度(du)的高溫中(zhong)進行(xing)電(dian)解(jie)。

以2020年為例：2020年中國電解鋁產量為3731.7萬噸(dun)，占全世界(jie)的(de)57.18%，僅電(dian)解鋁(lv)一項耗電(dian)總量就達到約4851.21億千瓦(wa)時(shi)。而(er)2020年中國全社會用(yong)電(dian)量也只有(you)75110億千瓦(wa)時(shi)，只是電(dian)解鋁(lv)就約占全國用(yong)電(dian)量的(de)6.46%。

二、電解鋁耗電量怎么算

電(dian)解鋁的耗電(dian)量是根據電(dian)流、時(shi)間、電(dian)壓和電(dian)解質濃度來計算的，具(ju)體(ti)方法如下：

1、確定電流大小

鋁(lv)制品供(gong)應總量、電(dian)解(jie)(jie)鋁(lv)的用途(tu)、原材料成本、發(fa)電(dian)機(ji)功率因(yin)數等(deng)眾多(duo)因(yin)素決定了電(dian)解(jie)(jie)鋁(lv)過程中的電(dian)流(liu)大小。電(dian)流(liu)的單位(wei)為安培(pei)，電(dian)流(liu)越大，耗電(dian)量就(jiu)越大。

2、確定電解質濃度

電(dian)(dian)(dian)(dian)解(jie)質指在電(dian)(dian)(dian)(dian)解(jie)過程(cheng)中起(qi)著導電(dian)(dian)(dian)(dian)和(he)溶(rong)解(jie)氧化鋁的(de)作(zuo)用(yong)的(de)化學物質。電(dian)(dian)(dian)(dian)解(jie)質的(de)濃度(du)會影響電(dian)(dian)(dian)(dian)解(jie)過程(cheng)的(de)速率(lv)和(he)耗電(dian)(dian)(dian)(dian)量。一(yi)般來(lai)說(shuo)，濃度(du)越(yue)大，電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓就越(yue)高，而(er)電(dian)(dian)(dian)(dian)流就越(yue)小(xiao)，反之亦然。

3、確定電壓大小

電(dian)(dian)壓(ya)(ya)指電(dian)(dian)解(jie)過程中使用的電(dian)(dian)源(yuan)電(dian)(dian)壓(ya)(ya)。電(dian)(dian)解(jie)鋁過程中的電(dian)(dian)壓(ya)(ya)大(da)小(xiao)會影響電(dian)(dian)流的大(da)小(xiao)和耗(hao)電(dian)(dian)量。電(dian)(dian)解(jie)鋁過程中所(suo)用的電(dian)(dian)源(yuan)的電(dian)(dian)壓(ya)(ya)通(tong)常與電(dian)(dian)解(jie)質的濃(nong)度和電(dian)(dian)流的大(da)小(xiao)有關。

4、計算時間

時(shi)(shi)間是指電解鋁過程(cheng)中電流通(tong)過的(de)時(shi)(shi)間。時(shi)(shi)間的(de)單位通(tong)常為秒(miao)、分(fen)鐘(zhong)或小時(shi)(shi)。

5、計算電解鋁的耗電量

電(dian)解鋁耗電(dian)量的計算(suan)公式為：電(dian)解鋁的耗電(dian)量（度(du)）=電(dian)功(gong)（千瓦時(shi)）x時(shi)間（小時(shi)）=電(dian)流（安培）x電(dian)壓（伏特(te)）x時(shi)間（小時(shi)）/1000。
