      原(yuan)料清(qing)(qing)液(ye)(ye)來自(zi)于純堿廠蒸氨廢液(ye)(ye)，將(jiang)這種(zhong)含鈣(gai)(gai)(gai)量能達(da)到(dao)(dao)15%的(de)清(qing)(qing)液(ye)(ye)壓濾液(ye)(ye)加酸降低其中(zhong)的(de)灰分(fen)，然(ran)后(hou)送(song)(song)(song)(song)(song)到(dao)(dao)蒸發系統進行(xing)(xing)提濃后(hou)送(song)(song)(song)(song)(song)到(dao)(dao)凈化(hua)崗(gang)位(wei)的(de)澄(cheng)清(qing)(qing)桶(tong)(tong)進行(xing)(xing)澄(cheng)清(qing)(qing)，回收固體鹽用于純堿生產，澄(cheng)清(qing)(qing)桶(tong)(tong)上層液(ye)(ye)溢(yi)流(liu)到(dao)(dao)鈣(gai)(gai)(gai)液(ye)(ye)桶(tong)(tong)中(zhong)，然(ran)后(hou)使用鈣(gai)(gai)(gai)液(ye)(ye)泵(beng)送(song)(song)(song)(song)(song)到(dao)(dao)蒸發系統再進一(yi)步提濃到(dao)(dao)40%，再送(song)(song)(song)(song)(song)到(dao)(dao)凈化(hua)崗(gang)位(wei)澄(cheng)清(qing)(qing)桶(tong)(tong)進行(xing)(xing)凈化(hua)，以(yi)除(chu)去鈣(gai)(gai)(gai)液(ye)(ye)中(zhong)的(de)雜(za)質。這種(zhong)成(cheng)品(pin)鈣(gai)(gai)(gai)液(ye)(ye)由(you)鈣(gai)(gai)(gai)液(ye)(ye)泵(beng)送(song)(song)(song)(song)(song)到(dao)(dao)片鈣(gai)(gai)(gai)崗(gang)位(wei)，經(jing)過第三次(ci)提濃到(dao)(dao)60%以(yi)上后(hou)，由(you)液(ye)(ye)下泵(beng)打到(dao)(dao)高塔造粒(li)機(ji)內進行(xing)(xing)噴灑造粒(li)，然(ran)后(hou)再由(you)傳送(song)(song)(song)(song)(song)帶將(jiang)成(cheng)型的(de)二水(shui)(shui)球狀(zhuang)氯化(hua)鈣(gai)(gai)(gai)輸送(song)(song)(song)(song)(song)至流(liu)化(hua)床內進行(xing)(xing)烘(hong)干，烘(hong)干后(hou)的(de)氯化(hua)鈣(gai)(gai)(gai)由(you)抖提機(ji)輸送(song)(song)(song)(song)(song)至篩分(fen)機(ji)進行(xing)(xing)篩分(fen)，這樣合格的(de)二水(shui)(shui)球狀(zhuang)氯化(hua)鈣(gai)(gai)(gai)就可以(yi)送(song)(song)(song)(song)(song)入成(cheng)品(pin)料倉(cang)進行(xing)(xing)包裝了。

      氯(lv)化(hua)(hua)(hua)(hua)鈣(gai)為(wei)(wei)無機化(hua)(hua)(hua)(hua)合物，是一種由氯(lv)元素和鈣(gai)元素構成的(de)鹽，化(hua)(hua)(hua)(hua)學式為(wei)(wei)CaCl2。它是典型(xing)的(de)離子型(xing)鹵(lu)化(hua)(hua)(hua)(hua)物，微(wei)毒、無臭、味微(wei)苦(ku)。室溫(wen)下為(wei)(wei)白色、硬質碎塊(kuai)或顆粒。吸濕性強(qiang)，二水(shui)(shui)氯(lv)化(hua)(hua)(hua)(hua)鈣(gai)，在空(kong)氣中極易(yi)潮解。易(yi)溶(rong)(rong)(rong)于水(shui)(shui)，氯(lv)化(hua)(hua)(hua)(hua)鈣(gai)，同時放出大量(liang)的(de)熱(re)（其水(shui)(shui)溶(rong)(rong)(rong)液呈微(wei)堿性。）低(di)溫(wen)下溶(rong)(rong)(rong)液結晶(jing)而析出的(de)為(wei)(wei)六水(shui)(shui)物，無水(shui)(shui)氯(lv)化(hua)(hua)(hua)(hua)鈣(gai)，逐漸加(jia)熱(re)至(zhi)(zhi)30℃時則(ze)溶(rong)(rong)(rong)解在自身(shen)的(de)結晶(jing)水(shui)(shui)中，繼續加(jia)熱(re)逐漸失(shi)水(shui)(shui)，至(zhi)(zhi)200℃時變為(wei)(wei)二水(shui)(shui)物，再加(jia)熱(re)至(zhi)(zhi)260℃則(ze)變為(wei)(wei)白色多孔(kong)狀的(de)無水(shui)(shui)氯(lv)化(hua)(hua)(hua)(hua)鈣(gai)。

      我公(gong)司采用(yong)流(liu)化床噴霧造粒干(gan)燥系(xi)統設備生產氯化鈣(gai)優勢(shi):

（1）系統整體熱，系統中所有(you)能夠利用的熱量均采用合(he)理的熱量回收工藝，從(cong)而(er)節(jie)能環保

（2）通過改變(bian)，可(ke)以(yi)實現噴霧干燥法生產(chan)，根據(ju)需要生產(chan)粉末(mo)狀氯化鈣。

（3）采用大口徑噴嘴，確(que)保噴嘴霧化的通暢性，可以連續運行(xing)。

（4）物(wu)料在干(gan)燥(zao)過程中干(gan)燥(zao)品質穩(wen)(wen)定均勻，具有極(ji)大的操(cao)作穩(wen)(wen)定性。

      氯化鈣是應用比(bi)較(jiao)廣泛的(de)(de)(de)防(fang)(fang)凍(dong)(dong)劑(ji)。因(yin)(yin)為氯化鈣溶于(yu)水后的(de)(de)(de)冰(bing)點在(zai)-30℃左(zuo)右，其冰(bing)點比(bi)水的(de)(de)(de)冰(bing)點（0℃）低(di)，因(yin)(yin)此在(zai)水中溶解了氯化鈣之后就會(hui)降低(di)冰(bing)點就難以再結(jie)冰(bing)。即使在(zai)更低(di)的(de)(de)(de)溫(wen)度下結(jie)了冰(bing)，其冰(bing)晶(jing)結(jie)構(gou)也發生變(bian)化，凍(dong)(dong)冰(bing)強(qiang)度減弱，用較(jiao)小外力就能夠使冰(bing)凍(dong)(dong)物(wu)破碎(sui)，達到防(fang)(fang)凍(dong)(dong)、解凍(dong)(dong)的(de)(de)(de)目(mu)的(de)(de)(de)。這就是氯化鈣可以用作防(fang)(fang)凍(dong)(dong)劑(ji)跟融雪劑(ji)的(de)(de)(de)原理(li)。

      氯化鈣(gai)（CaCl2）一(yi)種(zhong)由氯元素(su)和(he)鈣(gai)元素(su)組成的鹽，氯化鈣(gai)產品主(zhu)要有液體氯化鈣(gai)和(he)固體氯化鈣(gai)，因(yin)固體氯化鈣(gai)含量高、儲運方(fang)便，所以(yi)市售(shou)的氯化鈣(gai)大部分以(yi)固體為(wei)主(zhu)，外觀為(wei)白色(se)結晶(jing)體，為(wei)片(pian)狀、球狀、粉(fen)狀無水(shui)物和(he)二水(shui)物兩種(zhong)含量規格。
