一、電解鋁耗電量如何

電解鋁(lv)(lv)行業屬于高(gao)耗能(neng)企(qi)業，生產一(yi)噸電解鋁(lv)(lv)綜合電耗13500度(du)電，電解鋁(lv)(lv)對于電量需求(qiu)十分高(gao)，因(yin)為(wei)電解鋁(lv)(lv)的(de)過程是冰(bing)晶石和氧化鋁(lv)(lv)在900多(duo)度(du)的(de)高(gao)溫中進(jin)行電解。

以2020年為例：2020年中國電解鋁產量為3731.7萬噸(dun)，占全(quan)世界的(de)57.18%，僅電(dian)解(jie)鋁(lv)一項耗電(dian)總量就(jiu)達到約4851.21億(yi)千瓦時(shi)。而2020年中國(guo)全(quan)社會(hui)用電(dian)量也(ye)只有75110億(yi)千瓦時(shi)，只是電(dian)解(jie)鋁(lv)就(jiu)約占全(quan)國(guo)用電(dian)量的(de)6.46%。

二、電解鋁耗電量怎么算

電解(jie)鋁的耗電量是根據(ju)電流、時間、電壓和(he)電解(jie)質濃度來計算的，具(ju)體方法如(ru)下：

1、確定電流大小

鋁制品供應總(zong)量、電解鋁的用途、原材料成本、發電機功率(lv)因數等(deng)眾多(duo)因素決定了電解鋁過程中的電流大小。電流的單位為安培(pei)，電流越大，耗電量就越大。

2、確定電解質濃度

電(dian)(dian)(dian)(dian)解(jie)(jie)質指在電(dian)(dian)(dian)(dian)解(jie)(jie)過程(cheng)中起(qi)著導(dao)電(dian)(dian)(dian)(dian)和溶解(jie)(jie)氧化鋁(lv)的(de)(de)(de)作用(yong)的(de)(de)(de)化學物質。電(dian)(dian)(dian)(dian)解(jie)(jie)質的(de)(de)(de)濃度會影響電(dian)(dian)(dian)(dian)解(jie)(jie)過程(cheng)的(de)(de)(de)速率和耗(hao)電(dian)(dian)(dian)(dian)量(liang)。一般來說(shuo)，濃度越大，電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)壓就越高，而電(dian)(dian)(dian)(dian)流(liu)就越小，反之(zhi)亦然。

3、確定電壓大小

電(dian)(dian)(dian)(dian)壓指電(dian)(dian)(dian)(dian)解過(guo)程中使(shi)用(yong)的電(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)壓。電(dian)(dian)(dian)(dian)解鋁(lv)過(guo)程中的電(dian)(dian)(dian)(dian)壓大(da)小會影響電(dian)(dian)(dian)(dian)流的大(da)小和耗電(dian)(dian)(dian)(dian)量(liang)。電(dian)(dian)(dian)(dian)解鋁(lv)過(guo)程中所用(yong)的電(dian)(dian)(dian)(dian)源(yuan)的電(dian)(dian)(dian)(dian)壓通(tong)常(chang)與電(dian)(dian)(dian)(dian)解質的濃(nong)度和電(dian)(dian)(dian)(dian)流的大(da)小有(you)關。

4、計算時間

時(shi)間是(shi)指電解鋁過程中電流通過的時(shi)間。時(shi)間的單位(wei)通常為秒(miao)、分鐘或小時(shi)。

5、計算電解鋁的耗電量

電解鋁(lv)耗(hao)電量的計算公式為：電解鋁(lv)的耗(hao)電量（度）=電功（千瓦時(shi)）x時(shi)間（小(xiao)時(shi)）=電流（安培(pei)）x電壓（伏(fu)特）x時(shi)間（小(xiao)時(shi)）/1000。
