本技術(shu)涉及化工設備(bei)，具體涉及一種(zhong)萘法制苯酐生產中(zhong)的蒸汽裝置。

背景技術：

1、目前，利(li)用萘法制苯酐的(de)生(sheng)產(chan)中(zhong)，蒸(zheng)(zheng)(zheng)(zheng)汽(qi)系(xi)統主(zhu)要采(cai)用在生(sheng)產(chan)開始時輸入(ru)4.4mpa(450℃)過熱(re)蒸(zheng)(zheng)(zheng)(zheng)汽(qi)，然后利(li)用生(sheng)產(chan)過程(cheng)中(zhong)的(de)熱(re)量(liang)相(xiang)互轉化(hua)實現(xian)(xian)蒸(zheng)(zheng)(zheng)(zheng)汽(qi)的(de)利(li)用，但(dan)是發現(xian)(xian)現(xian)(xian)有(you)的(de)生(sheng)產(chan)工藝中(zhong)，產(chan)生(sheng)的(de)低(di)壓(ya)(ya)蒸(zheng)(zheng)(zheng)(zheng)汽(qi)因為沒(mei)(mei)有(you)足夠(gou)多(duo)的(de)裝置可以利(li)用，也(ye)沒(mei)(mei)有(you)外(wai)來用戶可以輸出，只(zhi)能(neng)通過閃蒸(zheng)(zheng)(zheng)(zheng)后變(bian)成低(di)低(di)壓(ya)(ya)蒸(zheng)(zheng)(zheng)(zheng)汽(qi)進行(xing)排放，造成蒸(zheng)(zheng)(zheng)(zheng)汽(qi)的(de)浪(lang)費，同時也(ye)逼迫增(zeng)加生(sheng)產(chan)開始時輸入(ru)的(de)過熱(re)蒸(zheng)(zheng)(zheng)(zheng)汽(qi)的(de)量(liang)，因此造成能(neng)源的(de)浪(lang)費。
