不銹鋼(gang)反(fan)(fan)應(ying)(ying)器是實現化(hua)(hua)(hua)學反(fan)(fan)應(ying)(ying)過(guo)程的設(she)備，廣泛應(ying)(ying)用于(yu)化(hua)(hua)(hua)工(gong)(gong)(gong)、煉(lian)油、冶金、輕工(gong)(gong)(gong)等(deng)工(gong)(gong)(gong)業部(bu)門(men)。例(li)如，氨(an)的合(he)成(cheng)反(fan)(fan)應(ying)(ying)就是經(jing)過(guo)造(zao)氣、精致，得到一定比例(li)、合(he)格純度(du)的氮氫混合(he)氣后，在(zai)合(he)成(cheng)塔中(zhong)，在(zai)一定的壓力、溫(wen)度(du)及催化(hua)(hua)(hua)劑的存在(zai)下起化(hua)(hua)(hua)學反(fan)(fan)應(ying)(ying)得到氨(an)氣。其他如染料、油漆、農藥(yao)等(deng)工(gong)(gong)(gong)業也都(dou)有氧化(hua)(hua)(hua)，氯化(hua)(hua)(hua)、硫化(hua)(hua)(hua)、硝化(hua)(hua)(hua)等(deng)化(hua)(hua)(hua)學反(fan)(fan)應(ying)(ying)過(guo)程則更為普遍。因此，反(fan)(fan)應(ying)(ying)設(she)備在(zai)化(hua)(hua)(hua)工(gong)(gong)(gong)設(she)備中(zhong)是非常重要(yao)的。反(fan)(fan)應(ying)(ying)設(she)備大多是工(gong)(gong)(gong)業生(sheng)產中(zhong)的關(guan)鍵設(she)備，例(li)如，合(he)成(cheng)氨(an)裝置中(zhong)氨(an)合(he)成(cheng)塔、聚乙烯裝置中(zhong)的聚合(he)釜都(dou)是該生(sheng)產中(zhong)的關(guan)鍵設(she)備。

  不(bu)銹鋼(gang)反(fan)應(ying)器(qi)用(yong)于實現液(ye)(ye)相單相反(fan)應(ying)過(guo)程(cheng)和液(ye)(ye)-液(ye)(ye)、氣-液(ye)(ye)、液(ye)(ye)-固、氣-液(ye)(ye)-固等多相反(fan)應(ying)過(guo)程(cheng)。器(qi)內常設有攪拌（機械(xie)攪拌、氣流攪拌等）裝置(zhi)。在高徑比(bi)較大時，可用(yong)多層攪拌槳葉。在反(fan)應(ying)過(guo)程(cheng)中物(wu)料需(xu)加熱(re)或冷卻時，可在反(fan)應(ying)器(qi)壁處(chu)設置(zhi)夾套，或在器(qi)內設置(zhi)換(huan)熱(re)面，也(ye)可通過(guo)外(wai)循環(huan)進行換(huan)熱(re)。
