2危險廢棄物(wu)處理流程和回轉窯焚燒爐簡介

2.1危險廢(fei)棄物處理流程(cheng)

焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)法因為(wei)(wei)其(qi)在廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理過(guo)程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)能夠大量(liang)處(chu)(chu)(chu)(chu)理廢(fei)(fei)(fei)棄產(chan)品而受到(dao)廣泛(fan)使(shi)用(yong)(yong)，在處(chu)(chu)(chu)(chu)理過(guo)程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)能夠減少廢(fei)(fei)(fei)棄物(wu)數量(liang)，同時(shi)(shi)不會造成二次污(wu)染(ran)，被認為(wei)(wei)是目前掌握的(de)有效的(de)一種危險(xian)(xian)廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理辦法。目前，我國所有的(de)危險(xian)(xian)廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理中(zhong)(zhong)(zhong)(zhong)心采用(yong)(yong)的(de)主要(yao)辦法也(ye)是通過(guo)焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)法進行(xing)廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理，該技(ji)術(shu)在西方(fang)國家(jia)(jia)已經有了長時(shi)(shi)間的(de)應用(yong)(yong)，達到(dao)了相當(dang)成熟(shu)的(de)水平，每年(nian)西方(fang)國家(jia)(jia)通過(guo)焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)法對(dui)廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理的(de)比率在60%以上。近幾(ji)年(nian)，危險(xian)(xian)廢(fei)(fei)(fei)棄物(wu)無害化(hua)處(chu)(chu)(chu)(chu)理要(yao)求越(yue)(yue)來越(yue)(yue)高(gao)，焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)法也(ye)會逐漸替(ti)代那些在處(chu)(chu)(chu)(chu)理過(guo)程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)可能產(chan)生二次污(wu)染(ran)的(de)處(chu)(chu)(chu)(chu)理辦法，焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)法對(dui)廢(fei)(fei)(fei)棄物(wu)處(chu)(chu)(chu)(chu)理的(de)比例(li)還會增加。目前，國內外常使(shi)用(yong)(yong)的(de)廢(fei)(fei)(fei)棄物(wu)焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐一共分為(wei)(wei)四種類(lei)型，分別為(wei)(wei)爐排焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐、爐床焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐、流(liu)化(hua)床焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐、回轉(zhuan)窯焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐。與(yu)其(qi)他幾(ji)種焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐相比，回轉(zhuan)窯焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐能夠進行(xing)更加廣泛(fan)的(de)廢(fei)(fei)(fei)物(wu)處(chu)(chu)(chu)(chu)理，適應性(xing)更強，能夠同時(shi)(shi)處(chu)(chu)(chu)(chu)理液(ye)態、固態、氣態的(de)廢(fei)(fei)(fei)棄物(wu)，對(dui)于(yu)處(chu)(chu)(chu)(chu)理對(dui)象的(de)寬容性(xing)也(ye)很高(gao)。正(zheng)是基于(yu)以上兩種特點(dian)，目前回轉(zhuan)窯焚(fen)(fen)(fen)(fen)燒(shao)(shao)(shao)爐污(wu)染(ran)物(wu)處(chu)(chu)(chu)(chu)理領(ling)域(yu)占有85%的(de)份額，是目前污(wu)染(ran)物(wu)處(chu)(chu)(chu)(chu)理過(guo)程(cheng)(cheng)中(zhong)(zhong)(zhong)(zhong)采用(yong)(yong)的(de)主要(yao)設備。

2.2回轉(zhuan)窯焚燒爐介(jie)紹

所謂回轉窯焚燒爐，指(zhi)的是(shi)本(ben)體(ti)內增設襯(chen)爐(lu)的焚燒爐(lu)，其(qi)中，本(ben)體(ti)材(cai)質為鋼板，本(ben)體(ti)形狀為圓(yuan)筒狀，襯(chen)爐(lu)具有良好的耐(nai)火效果。它主要有三種形式(shi)，第(di)(di)一(yi)種即(ji)熔融爐(lu)和非熔融爐(lu)，前(qian)者(zhe)焚燒溫度在1250℃左右(you)，它支持(chi)高分(fen)子(zi)化(hua)合物(wu)、有機物(wu)在同一(yi)時間進行處理，后(hou)者(zhe)燃(ran)燒溫度在1105℃左右(you)；第(di)(di)二種按照氣、固體(ti)在回(hui)轉(zhuan)窯內流(liu)動的方(fang)向(xiang)(xiang)，分(fen)為順流(liu)爐(lu)和逆流(liu)爐(lu)，前(qian)者(zhe)指(zhi)的是(shi)氣流(liu)方(fang)向(xiang)(xiang)與(yu)廢(fei)物(wu)流(liu)動方(fang)向(xiang)(xiang)一(yi)致，后(hou)者(zhe)指(zhi)的是(shi)氣流(liu)方(fang)向(xiang)(xiang)與(yu)廢(fei)物(wu)流(liu)動方(fang)向(xiang)(xiang)相反，利用廢(fei)棄(qi)物(wu)溫度差(cha)異顯著，能在短時間內完成水(shui)分(fen)蒸發；第(di)(di)三種是(shi)帶耐(nai)火材(cai)料(liao)或非耐(nai)火材(cai)料(liao)的回(hui)轉(zhuan)窯焚燒爐(lu)。

結語

隨(sui)著城市發展(zhan)，每天(tian)產(chan)生(sheng)的廢棄(qi)(qi)(qi)物(wu)數量居高不下(xia)，在這些(xie)廢棄(qi)(qi)(qi)物(wu)中，有(you)很多可能對(dui)環境造成(cheng)(cheng)嚴重污染，如醫療廢棄(qi)(qi)(qi)物(wu)和重金(jin)屬生(sheng)產(chan)產(chan)生(sheng)的廢棄(qi)(qi)(qi)物(wu)。如果不能及(ji)時處理這些(xie)廢棄(qi)(qi)(qi)物(wu)，它們就會對(dui)周圍環境造成(cheng)(cheng)嚴重的影響，有(you)的甚至會造成(cheng)(cheng)不可逆的影響。隨(sui)著相應經驗教訓的積累，回轉窯焚燒(shao)爐(lu)逐漸得(de)到推廣和應用，它是目前(qian)成(cheng)(cheng)熟的危(wei)險廢棄(qi)(qi)(qi)物(wu)處理方式(shi)
