一、電解鋁耗電量如何

電(dian)解(jie)(jie)鋁行(xing)業屬于(yu)高耗能企業，生產(chan)一噸電(dian)解(jie)(jie)鋁綜(zong)合電(dian)耗13500度電(dian)，電(dian)解(jie)(jie)鋁對于(yu)電(dian)量需求十(shi)分(fen)高，因為(wei)電(dian)解(jie)(jie)鋁的(de)過程是冰(bing)晶石(shi)和(he)氧化(hua)鋁在(zai)900多度的(de)高溫中進行(xing)電(dian)解(jie)(jie)。

以2020年為例：2020年中國電解鋁產量(liang)為(wei)3731.7萬噸，占全(quan)世界的(de)57.18%，僅電(dian)(dian)解鋁一項耗電(dian)(dian)總(zong)量(liang)就達到約(yue)4851.21億千瓦時(shi)(shi)。而2020年(nian)中國全(quan)社(she)會(hui)用(yong)電(dian)(dian)量(liang)也只有75110億千瓦時(shi)(shi)，只是電(dian)(dian)解鋁就約(yue)占全(quan)國用(yong)電(dian)(dian)量(liang)的(de)6.46%。

二、電解鋁耗電量怎么算

電(dian)(dian)解鋁的耗電(dian)(dian)量是根據(ju)電(dian)(dian)流、時間、電(dian)(dian)壓和電(dian)(dian)解質(zhi)濃(nong)度(du)來計算的，具(ju)體方法如下：

1、確定電流大小

鋁(lv)制(zhi)品供(gong)應總量、電(dian)解鋁(lv)的用途、原材料成本、發(fa)電(dian)機功率(lv)因(yin)數等眾(zhong)多因(yin)素決定了電(dian)解鋁(lv)過程中的電(dian)流大(da)小。電(dian)流的單位為安培(pei)，電(dian)流越(yue)大(da)，耗(hao)電(dian)量就越(yue)大(da)。

2、確定電解質濃度

電(dian)解(jie)質(zhi)指在(zai)電(dian)解(jie)過程中(zhong)起著導(dao)電(dian)和溶解(jie)氧化鋁的(de)作用的(de)化學物(wu)質(zhi)。電(dian)解(jie)質(zhi)的(de)濃(nong)度會影響電(dian)解(jie)過程的(de)速率和耗電(dian)量。一般來(lai)說，濃(nong)度越(yue)大，電(dian)源電(dian)壓就越(yue)高(gao)，而電(dian)流(liu)就越(yue)小，反之亦然(ran)。

3、確定電壓大小

電(dian)(dian)(dian)(dian)壓(ya)指(zhi)電(dian)(dian)(dian)(dian)解過程中使用的(de)電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓(ya)。電(dian)(dian)(dian)(dian)解鋁過程中的(de)電(dian)(dian)(dian)(dian)壓(ya)大(da)小(xiao)會影響電(dian)(dian)(dian)(dian)流的(de)大(da)小(xiao)和耗電(dian)(dian)(dian)(dian)量。電(dian)(dian)(dian)(dian)解鋁過程中所用的(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)濃度和電(dian)(dian)(dian)(dian)流的(de)大(da)小(xiao)有關(guan)。

4、計算時間

時間是指(zhi)電解鋁過(guo)程中電流通過(guo)的(de)時間。時間的(de)單位通常為秒、分(fen)鐘(zhong)或(huo)小(xiao)時。

5、計算電解鋁的耗電量

電(dian)(dian)(dian)解鋁(lv)耗(hao)電(dian)(dian)(dian)量(liang)的(de)計算公(gong)式為：電(dian)(dian)(dian)解鋁(lv)的(de)耗(hao)電(dian)(dian)(dian)量(liang)（度）=電(dian)(dian)(dian)功（千瓦時(shi)）x時(shi)間(jian)（小時(shi)）=電(dian)(dian)(dian)流（安(an)培）x電(dian)(dian)(dian)壓(ya)（伏特）x時(shi)間(jian)（小時(shi)）/1000。
