一、電解鋁耗電量如何
電(dian)(dian)(dian)(dian)解(jie)鋁(lv)(lv)行(xing)業屬(shu)于高耗能企業,生產一(yi)噸電(dian)(dian)(dian)(dian)解(jie)鋁(lv)(lv)綜合(he)電(dian)(dian)(dian)(dian)耗13500度電(dian)(dian)(dian)(dian),電(dian)(dian)(dian)(dian)解(jie)鋁(lv)(lv)對于電(dian)(dian)(dian)(dian)量需求十分高,因為電(dian)(dian)(dian)(dian)解(jie)鋁(lv)(lv)的過程是冰晶石(shi)和(he)氧(yang)化鋁(lv)(lv)在900多度的高溫(wen)中(zhong)進行(xing)電(dian)(dian)(dian)(dian)解(jie)。
以2020年為例:2020年中國電解鋁產(chan)量為3731.7萬噸(dun),占全世界(jie)的57.18%,僅電(dian)(dian)(dian)(dian)解鋁一項耗電(dian)(dian)(dian)(dian)總量就達到約4851.21億(yi)千瓦時。而2020年中國(guo)全社(she)會(hui)用(yong)電(dian)(dian)(dian)(dian)量也(ye)只有75110億(yi)千瓦時,只是電(dian)(dian)(dian)(dian)解鋁就約占全國(guo)用(yong)電(dian)(dian)(dian)(dian)量的6.46%。
二、電解鋁耗電量怎么算
電(dian)(dian)解鋁(lv)的耗電(dian)(dian)量(liang)是(shi)根據電(dian)(dian)流、時間、電(dian)(dian)壓(ya)和電(dian)(dian)解質濃度來(lai)計算的,具(ju)體方法如(ru)下(xia):
1、確定電流大小
鋁制品供應總(zong)量、電解(jie)鋁的(de)(de)用(yong)途、原(yuan)材(cai)料成本、發電機功率因數等眾多因素決定了電解(jie)鋁過程中的(de)(de)電流(liu)(liu)(liu)大小(xiao)。電流(liu)(liu)(liu)的(de)(de)單位為安培,電流(liu)(liu)(liu)越大,耗電量就越大。
2、確定電解質濃度
電(dian)解(jie)(jie)(jie)質(zhi)(zhi)指在電(dian)解(jie)(jie)(jie)過程中起著(zhu)導電(dian)和溶解(jie)(jie)(jie)氧化鋁的(de)(de)作用(yong)的(de)(de)化學物(wu)質(zhi)(zhi)。電(dian)解(jie)(jie)(jie)質(zhi)(zhi)的(de)(de)濃(nong)度會(hui)影響(xiang)電(dian)解(jie)(jie)(jie)過程的(de)(de)速率和耗電(dian)量。一般來說,濃(nong)度越(yue)大,電(dian)源(yuan)電(dian)壓就越(yue)高(gao),而電(dian)流就越(yue)小(xiao),反之亦(yi)然。
3、確定電壓大小
電(dian)壓(ya)指電(dian)解過程中(zhong)使用的(de)(de)電(dian)源電(dian)壓(ya)。電(dian)解鋁(lv)(lv)過程中(zhong)的(de)(de)電(dian)壓(ya)大小(xiao)會影響電(dian)流(liu)的(de)(de)大小(xiao)和(he)耗電(dian)量。電(dian)解鋁(lv)(lv)過程中(zhong)所用的(de)(de)電(dian)源的(de)(de)電(dian)壓(ya)通常與電(dian)解質的(de)(de)濃度和(he)電(dian)流(liu)的(de)(de)大小(xiao)有關。
4、計算時間
時(shi)間是指電解鋁過程(cheng)中電流(liu)通過的時(shi)間。時(shi)間的單位通常為秒、分鐘或小時(shi)。
5、計算電解鋁的耗電量
電(dian)解鋁(lv)耗電(dian)量(liang)的計算(suan)公式為:電(dian)解鋁(lv)的耗電(dian)量(liang)(度(du))=電(dian)功(千瓦(wa)時(shi)(shi))x時(shi)(shi)間(小時(shi)(shi))=電(dian)流(安(an)培)x電(dian)壓(伏特)x時(shi)(shi)間(小時(shi)(shi))/1000。
