通風、空調設備防火防爆措施1、空氣中含有容易起火或爆炸物質的房間，其送、排風系統應采用防爆型的通風設備和不會產生火花的材料（如可采用有色金屬制造的風機葉片和防爆電動機）。當送風機布置在單獨分隔的通風機房內，且送風干管上設置防止回流設施時，防火閥批發可采用普通型通風設備。2、含有易燃、易爆粉塵（碎屑）的空氣，在進入排風機前應采用不產生火花的除塵器進行處理，涪陵防火閥以(yi)(yi)防止(zhi)(zhi)除塵(chen)器(qi)工作過程中產生火花引(yin)起(qi)粉(fen)塵(chen)、碎屑燃燒或(huo)爆(bao)(bao)(bao)炸(zha)。對(dui)于(yu)遇濕(shi)可(ke)能爆(bao)(bao)(bao)炸(zha)的(de)(de)(de)粉(fen)塵(chen)（如電石、鋅粉(fen)、鋁鎂合金粉(fen)等），嚴禁(jin)采用濕(shi)式除塵(chen)器(qi)。3、排除、輸送(song)有(you)燃燒、爆(bao)(bao)(bao)炸(zha)危險(xian)(xian)的(de)(de)(de)氣(qi)(qi)體(ti)、蒸氣(qi)(qi)和粉(fen)塵(chen)的(de)(de)(de)排風系(xi)統，應(ying)采用不燃材(cai)料并設(she)有(you)導(dao)除靜(jing)電的(de)(de)(de)接地裝置。其(qi)(qi)排風設(she)備不應(ying)布(bu)(bu)置在(zai)地下、半(ban)地下建(jian)筑(zhu)（室(shi)）內，以(yi)(yi)防止(zhi)(zhi)有(you)爆(bao)(bao)(bao)炸(zha)危險(xian)(xian)的(de)(de)(de)蒸氣(qi)(qi)和粉(fen)塵(chen)等物(wu)質(zhi)的(de)(de)(de)積聚。4、排除、輸送(song)溫度(du)超(chao)過80℃的(de)(de)(de)空氣(qi)(qi)或(huo)其(qi)(qi)他氣(qi)(qi)體(ti)以(yi)(yi)及容(rong)易起(qi)火的(de)(de)(de)碎屑的(de)(de)(de)管道，與可(ke)燃或(huo)難燃物(wu)體(ti)之間(jian)應(ying)保持不小(xiao)于(yu)150mm的(de)(de)(de)間(jian)隙，或(huo)采用厚(hou)度(du)不小(xiao)于(yu)50mm的(de)(de)(de)不燃材(cai)料隔熱(re)，以(yi)(yi)防止(zhi)(zhi)填塞(sai)物(wu)與構件因受這些(xie)高(gao)溫管道的(de)(de)(de)影響而導(dao)致火災。當管道互(hu)為(wei)上(shang)下布(bu)(bu)置時，表面溫度(du)較高(gao)者應(ying)布(bu)(bu)置在(zai)上(shang)面。
