廢(fei)棄氫氧化鉀(jia)溶(rong)液(ye)回收(shou)的好處(chu)有哪些

　　氫氧化鉀外觀為白色片狀或粉狀，具有強烈腐蝕性和強堿性。氫(qing)(qing)(qing)氧(yang)(yang)化(hua)(hua)鉀(jia)暴露在空氣中時(shi)(shi)，極易(yi)被空氣中的(de)(de)水(shui)分而潮解(jie)，并吸收二氧(yang)(yang)化(hua)(hua)碳(tan)而成(cheng)碳(tan)酸鉀(jia)。氫(qing)(qing)(qing)氧(yang)(yang)化(hua)(hua)鉀(jia)易(yi)溶(rong)(rong)(rong)(rong)于水(shui)、乙(yi)醇(chun)或酸時(shi)(shi)，會釋放大量的(de)(de)熱量。但氫(qing)(qing)(qing)氧(yang)(yang)化(hua)(hua)鉀(jia)溶(rong)(rong)(rong)(rong)于乙(yi)醇(chun)溶(rong)(rong)(rong)(rong)液(ye)時(shi)(shi)，氫(qing)(qing)(qing)氧(yang)(yang)化(hua)(hua)鉀(jia)溶(rong)(rong)(rong)(rong)解(jie)慢不可以加熱助溶(rong)(rong)(rong)(rong)。因(yin)為氫(qing)(qing)(qing)氧(yang)(yang)化(hua)(hua)鉀(jia)和乙(yi)醇(chun)溶(rong)(rong)(rong)(rong)液(ye)可以在加熱條件(jian)下會反(fan)應生(sheng)成(cheng)乙(yi)醇(chun)鉀(jia)。在加熱時(shi)(shi)，同(tong)時(shi)(shi)在堿性條件(jian)下，乙(yi)醇(chun)容易(yi)被空氣中的(de)(de)氧(yang)(yang)氣氧(yang)(yang)化(hua)(hua)成(cheng)醛了。

　　氫氧化鉀生產中(zhong)液態廢堿(jian)(jian)主要(yao)指的是在開停(ting)車時的熔融(rong)堿(jian)(jian)，停(ting)車時清洗(xi)設備所形(xing)成的廢堿(jian)(jian)液。

　　采用(yong)增(zeng)加廢(fei)(fei)棄氫(qing)氧化鉀溶液(ye)回(hui)收的(de)(de)方法，能(neng)達(da)(da)到(dao)廢(fei)(fei)堿(jian)(jian)回(hui)收利用(yong)的(de)(de)效果(guo)，就是增(zeng)大廢(fei)(fei)堿(jian)(jian)排(pai)放管(guan)(guan)的(de)(de)垂直度，縮(suo)短管(guan)(guan)道的(de)(de)長度，將(jiang)廢(fei)(fei)堿(jian)(jian)排(pai)放管(guan)(guan)引入(ru)廢(fei)(fei)堿(jian)(jian)槽(cao)(cao)(cao)，廢(fei)(fei)堿(jian)(jian)槽(cao)(cao)(cao)所(suo)配(pei)有(you)的(de)(de)純水(shui)管(guan)(guan)線(xian)(xian)，用(yong)來稀釋(shi)廢(fei)(fei)堿(jian)(jian)的(de)(de)濃度。廢(fei)(fei)堿(jian)(jian)槽(cao)(cao)(cao)出口(kou)管(guan)(guan)線(xian)(xian)引入(ru)到(dao)除塵(chen)系統(tong)的(de)(de)廢(fei)(fei)氣(qi)洗滌(di)(di)泵(beng)進口(kou)管(guan)(guan)線(xian)(xian)，增(zeng)加的(de)(de)廢(fei)(fei)堿(jian)(jian)回(hui)收槽(cao)(cao)(cao)與堿(jian)(jian)塵(chen)除塵(chen)系統(tong)的(de)(de)廢(fei)(fei)氣(qi)洗滌(di)(di)槽(cao)(cao)(cao)之間能(neng)夠(gou)自如互相切換(huan)(huan)。在開車停車的(de)(de)過程中，將(jiang)廢(fei)(fei)氣(qi)洗滌(di)(di)液(ye)循環(huan)切換(huan)(huan)至(zhi)廢(fei)(fei)堿(jian)(jian)槽(cao)(cao)(cao)循環(huan)，當(dang)廢(fei)(fei)堿(jian)(jian)濃度達(da)(da)到(dao)5%時，將(jiang)堿(jian)(jian)液(ye)輸送至(zhi)一次鹽水(shui)工(gong)序配(pei)水(shui)槽(cao)(cao)(cao)，可作為部(bu)分(fen)化鹽水(shui)。
