烘干固化設備主要由烘干室體、加熱系統及溫度控制等部分組成。烘干室體有通過式、通道式;加熱系統的加熱方式有燃油式(重油、輕油)、燃氣式(天然氣、液化氣)、電加熱(遠紅外、電熱式)、蒸氣式等。

       烘干固(gu)化設備相對而言問題較少，但在保溫節能和安全性方面仍(reng)應引起(qi)注(zhu)意。

一、烘干室體外表面溫度過高

       室(shi)(shi)體保溫(wen)(wen)(wen)(wen)材(cai)料選用(yong)不(bu)(bu)(bu)當是造成(cheng)隔熱(re)效果較差、表面(mian)溫(wen)(wen)(wen)(wen)度超標(biao)(biao)和保溫(wen)(wen)(wen)(wen)性達不(bu)(bu)(bu)到要(yao)求(qiu)的主要(yao)原因(yin)。這不(bu)(bu)(bu)僅(jin)造成(cheng)能耗增加，也不(bu)(bu)(bu)符(fu)合國家標(biao)(biao)準GB1444321993《涂(tu)裝作業安全規程涂(tu)層烘(hong)干(gan)室(shi)(shi)安全技術規定》第(di)5.9.2條(tiao)要(yao)求(qiu)：烘(hong)干(gan)室(shi)(shi)應有(you)良好的保溫(wen)(wen)(wen)(wen)，外壁(bi)表面(mian)溫(wen)(wen)(wen)(wen)度不(bu)(bu)(bu)應高(gao)于室(shi)(shi)溫(wen)(wen)(wen)(wen)15℃。

二、廢氣排放管道設置不當或沒有設置

       有(you)(you)的涂(tu)裝線烘(hong)(hong)干(gan)固化室(shi)(shi)(shi)的廢(fei)(fei)(fei)氣(qi)(qi)排放管口(kou)沒(mei)有(you)(you)接到室(shi)(shi)(shi)外，而在(zai)車間內，廢(fei)(fei)(fei)氣(qi)(qi)直接排入車間里(li)，造成(cheng)車間內空氣(qi)(qi)污染;有(you)(you)的涂(tu)裝線烘(hong)(hong)干(gan)固化室(shi)(shi)(shi)的廢(fei)(fei)(fei)氣(qi)(qi)排放口(kou)沒(mei)有(you)(you)設置在(zai)廢(fei)(fei)(fei)氣(qi)(qi)濃(nong)度(du)最高的部位(wei)，不(bu)利于廢(fei)(fei)(fei)氣(qi)(qi)快速(su)排出，防止(zhi)積聚(ju)，也不(bu)符(fu)合國家(jia)標(biao)準GB1444321993第5.1.6條要求：烘(hong)(hong)干(gan)室(shi)(shi)(shi)內排氣(qi)(qi)口(kou)位(wei)置應設置在(zai)可燃氣(qi)(qi)體濃(nong)度(du)最高的區域。噴涂(tu)后(hou)的工件進入烘(hong)(hong)干(gan)固化室(shi)(shi)(shi)，由(you)于涂(tu)料不(bu)同程度(du)地含有(you)(you)機(ji)(ji)溶(rong)劑(ji)，烘(hong)(hong)干(gan)固化過程中(zhong)會產生有(you)(you)機(ji)(ji)溶(rong)劑(ji)廢(fei)(fei)(fei)氣(qi)(qi)，有(you)(you)機(ji)(ji)溶(rong)劑(ji)廢(fei)(fei)(fei)氣(qi)(qi)具有(you)(you)可燃性，如(ru)果廢(fei)(fei)(fei)氣(qi)(qi)未及時排出烘(hong)(hong)干(gan)室(shi)(shi)(shi)而積聚(ju)在(zai)烘(hong)(hong)干(gan)室(shi)(shi)(shi)內，一旦濃(nong)度(du)過高會造成(cheng)安全隱患(huan)。
